What constitutes RF coaxial connector reliability

Reliability refers to receiving the expected levels of performance from a cable assembly every time it is used, without degradation or loss in performance for the full lifetime of the application. Failure of a cable assembly can be expected when it exceeds the mechanical or electrical or environmental limits set for it, such as forming a flexible cable into a bend radius smaller than the recommended minimum or applying RF/microwave power levels higher than the rated maximum or operating the cable assembly at temperatures exceeding the specified operating temperature range. The definition of reliability becomes more complex when limits are set for performance degradation that is acceptable over time, and the performance of a coaxial cable assembly can be described by many different parameters, such as insertion loss, VSWR, and phase stability.
What constitutes RF coaxial connector reliability

The reliability of a cable assembly may be linked to maintaining tight control on just one or two performance parameters or on a full set of parameters. The required tolerances for what describes a hi-rel cable assembly can differ from one application to another. For example, a variation of ±2 dB in insertion loss over certain temperature and frequency ranges may constitute excellent reliability for a system requiring ±3 dB insertion-loss stability but may result in the failure of a system requiring ±0.5 dB insertion-loss stability. The reliability of a coaxial cable assembly is very much a function of an application and its operating environment.
The reliability of cables and connectors for military and aerospace applications is guided by many different military standards, such as MIL-DTL-17 coaxial cables and MIL-PRF-39012 RF coaxial connectors. MIL-DTL-17 covers many different applications, operating environments, and sets of performance specifications for different coaxial cables, with a great deal of attention paid to the center conductor dimensions and the materials chosen for the center conductor, such as tin, silver-coated copper, and copper-clad steel conductors.
Coaxial connectors for military and aerospace applications must often meet the standards contained within MIL-PRF-39012, which is used by all departments and agencies of the U. S. Department of Defense (DoD). It covers general requirements and test methods for characterizing RF connectors used with flexible and semirigid coaxial cables for military applications, and applies to many different types of connectors, including field-serviceable and non-field-serviceable connectors.

What should I pay attention to when designing USB Type-C?

Today's USB type-c standard has gradually become the mainstream of USB connector interface. The production design and development of smarter connectors, plug interfaces and USB cables are the issues and development directions that connector manufacturers need to pay attention to. USB type-c The range of applications that the standard can provide is also increasing, and the rules of this series are continuing to evolve. Such a solution can be connected without separate power adapter data and power transmission, and is widely used in portable devices, data centers, infotainment systems, and outdoor LED display devices. Therefore, engineers need to pay attention to three key design points when designing USB Type-C connectors.
What should I pay attention to when designing USB Type-C?

power supply
It is critical that the USB Type-C connector cable sends and receives the right amount of power and requires the correct components. A suitable resistor and a system for leveling power will ensure that the cable consumes only the same amount as the host device. Electrical energy.
Multi-function signal transmission
The USB Type-C standard also requires cables to use precise wire sizes and the correct connector construction. Proper signal integrity, as well as protection against RF and electromagnetic interference, allow the multifunction signal to work effectively. Vendors with some USB Type-C connector solutions can provide a shield design on the back of the socket housing to help eliminate unwanted electromagnetic interference (EMI) leakage.
Sturdy structure
Enhanced retention and splash-proof options should be provided during product design to ensure that USB Type-C connectors can operate in harsh industrial environments, which requires enhanced environmental sealing and mechanical strength. For beginners, the IEC-60529-IP67 specification ensures a joint seal to prevent ingress of dust and is protected by high pressure water jets. It also supports immersion in water for a limited time.
On the other hand, the rugged construction of the USB Type-C connector can be done with upgraded materials such as gold-plated and nickel-plated contacts to prevent corrosion. Design features such as conductive silicone rubber gaskets and threaded panel connection points also allow the connector to operate in extreme environments, and the USB Type-C connector also features through-hole mounting for a mechanically robust PCB connection.

What are the advantages of the circular connector

In the process of production of circular connectors, after repeated research by technicians, the production process has been gradually improved, and in the process of assembly, the device process of electronic products has been gradually simplified, and the batch production process is also Continuous simplification. In addition, when the device is in use, there is an accident or some kind of electronic component failure, if the device uses the connector, the component of the component can be replaced relatively quickly, and thus the advantages of the circular connector are also It is easier to repair. 

What are the advantages of the circular connector


With the continuous development of modern technology, the components of the equipment are relatively easy to fall behind. If the device is installed with a connector, the update of the device is more convenient, which is of great help to maintain our equipment and production. 

When designing and manufacturing new products, professional engineers can use the latest system of component parts. At this time, the flexibility of the connector can be realized, and the flexibility of product design can be effectively improved. In short, it is precisely because of the obvious advantages of the circular connector, therefore, in the construction machinery industry, the concept of this circular connector has been widely used, automotive parts production lines, electrical and electrical systems, instrumentation, minerals, Oil and gas drilling and anti-corrosion engineering wind energy and solar energy, etc., as well as automated substations and other fields have been widely used, more and more meet customer needs, and have been loved by customers.

Improve the durability of fiber optic connectors

The horizontal fiber optic splice connector is an indispensable part of the optical fiber communication line. Its main function is to realize the connection of the optical fiber cable. At the same time, in order to ensure the grounding function of the optical fiber connector, the internal grounding device and the grounding portion of the optical cable should be electrically connected, and the optical fiber. The metal parts of the connector and the grounding device should be electrically connected. In order to avoid adverse effects on the cable joint closures, it is important that they are insulated from one another and that the pressure resistance of the fiber connector joints is improved.

Improve the durability of fiber optic connectors


In order to prevent lightning strikes or other factors, the fiber splice connector must meet the standard application of 15 VDC for 1 minute without breakdown and no arcing. Therefore, high requirements are placed on the fixing and grounding of the fiber splice connector and the design of the insulating material used. Reasonable and sturdy insulation is the fundamental guarantee for high voltage DC breakdown. There are many insulating materials on the market today, but we need to make appropriate choices based on the standard requirements, combined with the dielectric properties and plasticity of the material itself.

Therefore, the structure and material of the insulation as well as the surface condition also have a great influence on the withstand voltage strength performance of the fiber splice case. If you want to improve the withstand voltage performance of fiber splice connectors, you must use a better insulating material, such as Teflon, to increase the surface finish and reduce the curvature between the insulators and between the poles. Insulating gaskets commonly used in fiber optic splice closures typically consist of two upper and lower spacers, the upper washer being a recessed washer and the lower washer being a male washer.

2019年7月24日星期三

Prospects for FPC connectors

FPC connector This type of connector, in addition to some electronic engineers, many of us may not have a specific understanding of the concept. So we often come into contact with connectors. For example, we often use computers, cars, mobile phones and important components that are indispensable in all kinds of home appliances. Connectors are an important bridge for communication and communication between various parts, and they are widely used in real life. After social and economic development, China has become the world's largest connector production base, and the FPC connector is a type of connector, which is now mainly used in mobile phone.

Prospects for FPC connectors

So what is the FPC connector? The FPC connector is a PCB made of soft material that can be used on a mobile phone for a simple circuit link, which is known as a cable, and it can also be used as a complex circuit. With the increasing use of mobile phone applications, the application of FPC connectors will be more and more, and the types of FPC connectors are also various. For example, LED display screens need to be connected to the PCB to the FPC connector, although the 0.3mm pitch FPC connector products have been put into use. However, with the continuous development of technology, it is gradually developing towards 0.4. In the future, the number of pins of the FPC will be reduced, and the components of other mobile phones will be placed together in the frame of the LED, so the FPC connector is oriented toward precision, Simple, convenient and miniaturized.
The development of board-to-board connectors is also evolving, and will become smaller and smaller in the future. The height of the pins and the pitch of the pins will become smaller. Although it is still dominated by 0.4mm, it is moving toward 0.35. Direction development. Reducing the volume is bound to be the development trend of FPC connectors, and the visual effects and waterproof functions are also the future development trend. The connector for the battery, as one of the FPC connectors, will be further miniaturized, enabling low contact resistance and improving connection reliability.

Increase the life of connector electronics

The useful life of connector electronics can often determine the life of an electronic connection system in the industry, from manufacturing to automation. When troubleshooting after a machine or connection system failure, the failure may be related to a failure of the connector electronics of the critical system. What problems should we pay attention to in order to prevent this from happening?

Increase the life of connector electronics

Heat is the number one enemy of electronic components and one of the main reasons for the failure of early manufacturing products. Thermal damage is caused by improper cooling, which greatly reduces the reliability of the components. Every electronic component should be manufactured with the ideal operating temperature in mind, and if you exceed the operating temperature limit, you should be aware of this.
When an electronically connected device uses an open loop cooling system, ambient air is blown through the electronic components to remove the operating heat of the connector. For example: add a blower, fan or electric impeller. They can be mounted at or around hot spots to prevent thermal damage to the connector electronics. But the open loop system can only achieve so much, if the surrounding air is very hot, it can only reduce a certain amount of heat.
A closed loop cooling system reduces temperature while keeping ambient air unaffected by the system. Air or water and air heat exchangers are examples of closed loop systems,whice is an ideal solution when the ambient temperature is too high for the open loop system, or if the air is highly contaminated and the filtration system is not sufficient for disinfection.

Connector manufacturer's development difficulties

Connectors provide a reliable interconnection for a wide variety of electronic devices, thus attracting a lot of people to invest in them. During the years of connector product innovation design exhibitions, many small and medium-sized connector manufacturers expressed their development difficulties in the connector industry. So what is the reason why many small and medium-sized connector manufacturers have developed so difficult? The following is the reason for everyone to analyze.

Connector manufacturer's development difficulties

Foreign connector manufacturers have greater capital and advanced technology. With the advancement of mobile phone technology, they have conducted more in-depth research on connectors, which has gradually widened the gap between Chinese manufacturers and them. Even if we can extend the life of the connector to 5ys, the quality of foreign connectors still exceeds that of our Chinese manufacturers.
Small and medium-sized connector manufacturers lack some of the necessary materials, so we have to import most of the materials, and our industry does not have a solid brand chain to attract more customers.
Because of these shortcomings, we need to create an advantage for us. Now our manufacturer has the advantage over foreign products is faster delivery cycle and lower price, and we can completely design our own mold according to customer needs, these foreign companies can not keep up. Due to the financial crisis, our domestic products can lower prices and put more pressure on foreign companies.

what is a dual DVI interface connector

Dual DVI is a digital video interface connector with 24 pins arranged in a grid-like rectangular format on the right side. A dual DVI interface connector, also known as a dual link, can be used as a connector on an electronic device such as a personal computer or a high definition television (HDTV). The fllowing is mainly introduce you to what is a dual DVI interface connector.

what is a dual DVI interface connector

The DVI connector is replacing the video graphics array VGA connector. The VGA connector is still commonly used in 2011 to connect a display to a desktop PC or as an external display connector for a laptop. A properly named DVI is used for digital video display compared to a VGA that transmits an analog video signal.
The dual DVI pins are responsible for the passage of digital video signals. The dual DVI has six pins more than a single DVI, and the number of pins in a single-link DVI connector is 18. The additional pins on the dual-link DVI connector increase the bandwidth, which is the frequency range required to transmit the video signal.
Therefore, dual-link DVI allows for higher graphics display resolution than single-link DVI. The graphic display resolution represents the number of pixels that can be placed on the display. A single DVI can manage resolutions up to 1,920 x 1,200 pixels. The dual DVI goes beyond a single DVI with a maximum display quality of 2,560 x 1,600 pixels.
Another result of dual-link DVI increasing bandwidth is the ability of the signal to travel farther than a single DVI. The maximum cable length for established DVI cables is approximately 16 feet (5 meters). Dual DVI interface connectors can not only transmit digital video signals, they can also accommodate analog mono, which is the same as the VGA connector. The two types of dual-link connectors are: DVI-integrated (DVI-I) and DVI-Digital (DVI-D), and DVI-I includes digital and analog video pins to accommodate any type of computer monitor. DVI-D is only used for digital visual display.

Industrial connector core advantages

Industrial connectors are electronic products that are often touched by engineers and technicians. They act as connections in the circuit to allow current to flow. The arrival of the smart industrial era has also brought springs of opportunities for industrial connectors, especially in the fields of industrial automation, robotics and motor control, which are promoting the development of the connector industry.

Industrial connector core advantages

An important core advantage of industrial connectors is the ability to provide solutions for distributed control systems. So-called distributed control systems typically have a human-machine interface for human body control and system monitoring, and are connected to a programmable controller via a communication network connection. These controllers are then connected via fieldbus to the different units involved in the automation operation, such as actuators, motors, sensors, switches and valves.
The development of industrial connectors will be a major reform and advancement of connectors in industrial applications, laying a good foundation for our industrial development and providing great convenience for our lives. Nowadays, industrial connectors are advancing with the times, and they are constantly becoming humanized and technological.
The main function of the industrial connector is the connection between the industrial liquid containers so that the various parts can be connected together. This new design not only changes the status quo of industrial connector consumables, but also solves the problem of inconvenient installation of industrial connectors, and lays a new monument for the development of industrial connectors.

Refinement is the future trend of connectors

With the continuous development and advancement of multimedia and other technologies, connectors are also adapting to the constant changes of their subjects. In view of this, with the USB connector, the USB connector used in the original MP3 player is not rough, and the overall connection line is too long and cumbersome for better carrying and saving.

Refinement is the future trend of connectors

Now that it has evolved into the MP5, its USB connector has been streamlined in appearance and more durable. With the development of science and technology, a good connector not only has a more beautiful appearance, but also has more and more durable materials. More importantly, the design of the card slot connection at the core is more and more refined. And precision. In this way, the data connector will not be used for a long time, the card slot will be loose or the data transmission of the connector will be interrupted, which will greatly hurt the customer's purchasing confidence in the main product.
Although the connector is not so important compared to the core part of the product, it lacks its connection, and I am afraid that the actual role of the core will be greatly limited. It's like a ribbon connector in a computer case. If the high-current connector does not have its current data transmission function, at the current state of the art, I am afraid that the high-end PC will become complicated. Today's connectors are not the best, and the continuous development of science and technology has provided better technical support for connectors of various purposes. These advanced technologies are not only reflected in the green durability of the connector, but also in the more convenient, economical and flexible. Now the future development trend of connectors will also be toward the direction of refinement.

Sealing scheme for electrical connectors

Low-frequency unsealed electrical connectors are widely used in military electronic equipment, and their reliability directly affects the normal operation of equipment. When the ambient air humidity is close to saturation, or because the metal exchanges heat with a low temperature object in the environment, the metal surface is prone to condensation, resulting in a decrease in insulation of the electrical connector. Nitrogen and sulfide in the atmosphere combine with water vapor to form a salt solution to form electrolytic corrosion on the metal surface. When the density of the metal surface coating is not high, the micro-battery is provided for the electrolytic solution of the salt solution. The greater the potential difference between the gold plating layer and the intermediate plating layer, the more serious the electrolytic corrosion. The working environment of military electronic equipment is complex and changeable. The low-frequency unsealed electrical connector has a low sealing level. The high temperature, damp heat, salt spray and other harsh factors cause frequent failure of the electrical connector.

Sealing scheme for electrical connectors

At present, some electrical connectors are designed with a sealed structure to improve the reliability of the electrical connector in a humid environment. For equipment, the replacement and replacement of electrical connector seals involves a wide range and is difficult. In order to explore the sealing technology of unsealed electrical connectors, this paper takes the low-frequency circular electrical connector as an example to study the sealing process of the electrical connector tail and the sealing process of the mating surface. The sealing effect is tested by environmental test and electrical insulation performance test. The verification was carried out, and the recommended method for electrical connector sealing protection was proposed for different working conditions.
The contact of moisture, salt spray, etc. with the inner conductor of the electrical connector is the main cause of failure of the electrical connector. The typical structure of the low-frequency unsealed electrical connector is shown in Fig. 1. According to the analysis of the structure, the external water vapor and salt mist mainly enter the casing through the two paths of the electrical connector tail and the mating surface, and are attached to the inner conductor surface. The rear end of the electrical connector has a large gap, and the inner conductor and the cable core of the electrical connector are barely exposed in the external environment; the gap of the connector surface of the electrical connector is not obvious, and the moisture is not easily dissipated once it enters, causing long-term instability to the electrical connector. hurt.
At present, the low-frequency unsealed electrical connector seal protection is mainly composed of two-component adhesive agent in the tail. Different glues need to be matched according to the ratio. The external field operation is difficult, and the tail glue can not solve the sealing problem of the plug surface. The salt mist still enters the electrical connector housing path through the mating face. The sealing process used in this paper is divided into two parts: the tail seal and the insert face seal. The tail seal adopts one-component and two-component glue filling processes to cope with different working environments; the insert face seal adopts the tape wrapping process to ensure Improves productivity and operability in the case of a sealing effect.

2019年7月8日星期一

Why does the connector cause bad phenomena

Regardless of the product being manufactured, as long as the quality of the product is not enough, it will cause a variety of problems, and even more serious threats to the personal safety of people when using the product. For example, the connectors and junction boxes in photovoltaic modules are small and precise small parts, but these two small parts will be a huge safety hazard if they are not in quality! Up to now, there have been too many fires in our country due to overheating of connectors, which has brought huge economic losses to the power station.

Why does the connector cause bad phenomena

After investigation, the root cause of the fire is that the resistance of the connector increases under the condition of the flow, which causes the temperature rise to increase and exceed the temperature range that the plastic casing and the metal parts can withstand, thereby causing a fire. Therefore, the failure of the connector and the fire caused by the combination of the plastic casing and the metal parts, the following three failure analysis may help you understand the knowledge.
the failure analysis of the resistor Rco
The resistor Rco is the resistance of the connector to the overlapped part of the metal piece. If the Rco is abnormally increased, the temperature rises, which may cause a fire in the middle of the connector. The crimping resistor Rcr is mainly related to the crimping quality and the crimping process. We can judge the quality of the crimping by the compression ratio and the crimping profile. A good crimping requirement requires that the profile be tight without gaps and that the shape is regular. For the commonly used 4mm2 cable crimping, the contact resistance at the crimping point, the standard IEC2742/05 also proposes a requirement of less than 0.2mΩ, while the IEC60352-2 specifies that the pull-out force of the crimping end is greater than 310N.
the failure analysis caused by sealing performance
Because the connectors in the PV modules are outdoors, there are strict requirements for sealing performance. For example, some connectors have achieved IP65 and IP68 protection levels. Since the connector is mated to the cable, the choice of cable becomes very important when it comes to sealing. In general, different connector models will correspond to different cable ODs, the purpose is to ensure sealing performance. In order to verify the compatibility of the cable, the connector should be tested after it is assembled, such as IP test, wet insulation test and withstand voltage test. In another case, it is difficult to ensure the sealing property of the connector. Therefore, in outdoor applications, it is possible to inject water into the dust, thereby damaging the insulation performance and causing a fire.
the failure analysis caused by insulation materials
In the manufacturing process, the choice of insulation material directly determines the quality of the connector. A good connector needs to select a suitable insulation material, and whether it is suitable is mainly determined by the connector use requirements. For example, weather resistance, heat resistance, flame retardancy, mechanical properties, insulation properties of materials, etc., and the choice of connector insulation materials in photovoltaic modules is the result of comprehensive consideration of these properties. Some manufacturers use recycled materials to reduce the cost of product materials, but they increase the probability of failure of the product at the use end, so choosing the right material can reduce the probability of fire at higher temperature rise. Therefore, customers should eliminate the use of recycled materials for manufacturing when selecting the connector manufacturers.

Historical perspective of industrial connector design

Whether it is a professional electronic product user or a data center support technician or engineer, the appearance and operation of the connectors and cables used are similar, but there are many considerations for the design of industrial connectors. Connector manufacturers are mainly for the historical view of industrial connector design for many years.

Historical perspective of industrial connector design

As early as the 1970s, connector plugs were macroscopic in size because they were filled with large and medium palms and most of the fingers were used for gripping. People with smaller hands and fingers sometimes need to connect or disconnect the I/O interface copper cable assembly with both hands. It seems that most connector plugs and cables are too large for the average person, especially in the manufacturing industry.
At that time, the large gray thick metal back shell of the industrial connector assembly used a metal jack fastener of 6-60 size or larger. Cables and wires are also very large in diameter, usually between 18-22 AWG. This causes the cable assembly to be very heavy and difficult to align with the interface, pushing the plug into its mating receptacle connector. Because the connector plug is rectangular or block-shaped, it has a huge rib grip function. It also appears to have 25 gray overmolded plugs, usually with a smooth matte finish and cable jacket. Even some of the original cables have linear ribbed jackets. Industrial design specifications have been developed for testing, measurement and telephone equipment.
By the 1980s, connector plug sizes were often referred to as miniatures, sometimes ultra-small, and typically reduced overall size by about one-third. This new size range makes the connection easier. The metal backshell seems to have disappeared, and overmolded plugs with internal thin metal shields are the most common. Molded 4-40 molded thumbscrews are easier to use and take less time to fix. Typical wire gauge sizes are reduced to approximately 24 AWG, but the number of circuits is typically higher, so the cable diameter is still large, which leads to clumsiness in cable handling and wiring. It seems that 25 kinds of beige overmolded connector plugs have been developed in the past ten years, but everything seems to be the same, people are tired of it.
In the 1990s, connector plug sizes were again reduced, mostly called ultra-small, with some miniatures. This again reduces the average size by about 30%. The average wire diameter is reduced to 26-28 AWG. Overmolded connector plug plastic rear case with metal sprayed inside for shielding. Finally, the average cable diameter began to shrink over the decade, while the average connector component and cable assembly weight was also decreasing. The overall design is more in line with people's love, and the air flow in the equipment rack is better. Fasteners are typically latched or push-pull for more efficient link times.
Today's industrial connector plug housings, rear and overmolded parts, and cable jackets are almost all black, because grit and film protect the environment of these connectors and cables, so they look cleaner. Some devices are difficult to find the correct cable plug to disconnect or connect it because everything in the rack is black.

What the medical connector should have

Connectors are a small component in the ambitious design of medical devices, and some may think that connectors are a negligible part of medical devices. However, it is important to know that the connector plays a huge role in the normal functioning of the device. With the advancement of medical technology, medical connectors are increasingly demanding safety, reliability, shape and speed of receiving the signal.

What the medical connector should have

Medical connector security
When patients receive treatment, the last thing they want to touch is danger. Although the dangers are not common, it is reported that some cases of contact with medical connector conductors that cause serious injury or even casualties are commonplace. In the resolution, the IEC proposed a standard that requires connectors used in medical applications to contain an insulated form that prevents people from being shocked during contact, further enhancing the safety of modern medical devices.
Medical connector reliability
As medical technology advances, the equipment used is constantly evolving, and the professionals we rely on rely on the perfect operation of their equipment. While connectors look like a trivial component in this complex device, they play a key role in the reliability of medical devices. When the connector is used as a connection between the probe and its medical device during operation, the connector is expected to function perfectly, because the reliability of the connector can directly affect the success or failure of the surgery, which is related to the patient's life. This is why the medical industry continues to invest in connectors that have proven to provide reliable performance over the life of the device.
Medical connector components
Similar to smartphones, medical devices also have form factors. Due to recent medical advances, surgeons can perform certain procedures. Some medical devices allow surgeons to perform their complex operations, such as heart bypass surgery, which requires the creation of a small incision and the insertion of a laparoscopic camera. The success of these types of operations also depends on the complex components within the medical device, such as connectors, and the functional capabilities of the surgical system to perform and optimize the device.
The speed at which the medical connector 
To ensure the success of this minimally invasive medical procedure, previous surgeons monitored images that facilitated these types of operations from images transmitted in real time from laparoscopic cameras in the patient's body. Modern connector technology allows these large amounts of data to be transmitted at high speeds with high integrity, which greatly facilitates the success of these operations.

the performance of Medical connector

Just as doctors need to pass medical boards, medical connectors need to pass many tests to ensure they meet the stringent safety, performance and reliability standards required to work in the medical field. In addition, medical connectors must also undergo routine disinfection and abide by a series of strict regulations. The following mainly introduce 10 performance characteristics to ensure the safety of medical connectors!

the performance of Medical connector

For proper operation in a medical environment, the medical connector should meet the following 10 performance characteristics:
1. Ensure medical connector signal integrity (using leading connector technology).
2. The medical connector is to achieve a completely secure connection.
3. The medical connector needs to be sealed and sterilized.
4. Make sure the medical connector is free of electromagnetic interference.
5. Medical connectors need to be durable and durable.
6. Medical connectors are subject to RoHS and REACH requirements.
7. The medical connector design is easy to operate.
8. Medical connectors must have a safe and easy mating procedure.
9. Medical connectors are preferably streamlined, color coded product designs.
10. The shape of the medical connector is light and compact.
These connectors are used in a variety of medical applications such as diagnostic equipment, medical imaging, therapy, surgical instruments and cardiac assistive devices. They must be consistent and trustworthy so that doctors, nurses and other medical staff can rely on them in demanding situations. If the connector is not designed properly, its use may result in injury or death to the patient. To prevent this from happening, the connectors are rigorously tested before use and it is recommended to test them periodically afterwards to ensure they still operate at optimum performance levels.

Connector's knowledge

After years of development and advancement of electronic information technology, connectors have become the key components of current or signal connection. Although the connector products are small in size, simple in function and structure, but the connectors are numerous, large in number, and most of the electronic connectors. Engineers often face the following dilemmas:

Connector's knowledge

1. Electronic connector engineers will be confused in the design of problems and treatment methods that need to be considered in addition to functions.
2. Reasonable selection of product routine experimental items, analysis of test results and response methods are not well understood.
3. It is difficult to give a targeted solution to the failure analysis that occurs in the application of the product.
In addition to the key technical difficulties of the connector, on the other hand, the reliability of the product can not be ignored, including the reliability design, evaluation and testing of the product. Many times people are discussing the importance of quality or reliability in connector products, while others believe that good quality connector products represent a high reliability of the connector. This view is wrong. The reason why people have this view is that there is no overall understanding and understanding of the connector. In fact, 90% of the connector technology requirements are the same or figured out. The technical division of the connector products is to master the connector technology. Effective means.
The birth of new connector products requires two types of technologies: design technology and manufacturing technology, where the manufacturing technology is not unique to the connector, but part of all the manufacturing techniques required for connector manufacturing. The expertise and technology of the connector itself is applied to the connector design, so mastering the expertise of the connector is a must for the design engineer. New energy vehicle connectors, rail transit connectors, aerospace connectors, etc., which we commonly see, are divided from a market perspective.
On the other hand, from a technical point of view, connectors should be divided into two categories: high-current high-voltage power connectors and low-current low-voltage signal connectors; from the design goal, the connectors can be divided into functional design and Reliability design. Therefore, the above said: the technical division of the connector is an effective means to master the connector technology, the basic rules of the connector technology can be combed and mastered in a short time, but the reliability design requires more energy to Research and promotion.
