How to improve the manufacturing technology of the connector

The connector is one of the most popular and most used components in the electronics industry. The product quality and productivity of the connector have always been an important parameter in the fierce competition in the connector industry. So how to improve the connector manufacturing level is a problem that manufacturers need to consider. Connector manufacturing process technology innovation is the driving force for the development of the connector industry today, and connector technology innovation is to have bold thinking, the courage to try to prove the results, and the reverse thinking skills.

In fact, not only in the connector industry, it can be said that in all industries, innovative thinking practice and development can be carried out from several aspects such as manufacturing process and product materials. For example, many connector manufacturers now encounter bottlenecks in the efficiency of connector plating process. Therefore, improving the plating efficiency of products is an important issue in the connector plating process. What kind of material is used in the manufacture of the product is also a major factor affecting the quality of the connector.

Nowadays, some large connector manufacturers in the world have already adopted fully automatic electroplating production line processes. Nowadays, the production lines for connector electroplating processes include: vibrating electroplating production line, strip (wire) production line and barrel plating production line; With the development of technological innovation in the industry, connector products have different types of connector product types when application objects, frequencies, powers, and application environments are different. For example, the connector on the communication device acts as a physical layer device, which affects the reliability and performance of the transmission system to some extent.

Today, there are nearly 1,000 manufacturers engaged in connector manufacturing in China, which improves the innovative process and connection technology of connectors, simplifies terminal connection and maintenance services, reduces the need for hard-wired connections, and enables design and production. The process is more convenient and flexible, reducing production and maintenance costs. Experts in the industry also said that new product materials, new technologies and new processes will continue to penetrate into the product manufacturing field of connectors, and improving the manufacturing level of domestic connectors is a problem that all connector manufacturers need to care about.

Some knowledge about electronic connectors

In the electrical and mechanical industry and manufacturing, each of a pair of mating connectors or fasteners is typically designated as male or female. A "female" connector is typically a socket that houses and holds a "male" connector. Sometimes the connector pairing terms "male" and "female" are called the end of A and B respectively, and some standard names also conflict with this because they contain the letters A or B in the name; but it is rare, the term includes Plugins and sockets or jacks, although this can be confusing when used in everyday sessions.

In some cases, the electrical flow of an electronic connector from one device to another will select the gender of the connector according to strict rules to enforce a one-way sense of direction. This gender distinction is implemented to enhance security or ensure proper functionality by preventing unsafe or non-functional configurations from being set up. In the case of mathematical graph theory, the power distribution network consisting of a plug and a socket is a directed tree, and the directional arrows correspond to the electrical conversion of the electrical to the mother through each mating connection. Male and female connectors are deliberately designed and distributed to physically implement a secure network topology without forcing a one-way flow through connector gender assignment. The flow through the pipeline network can be bidirectional, as in a groundwater distribution network with design redundancy. It is desirable in the case of a one-way flow conduit, which is achieved by other means, such as gravity flow, one-way check valves, rather than through a male-female gender regime. Let's talk about the sex of the connector's mechanical fasteners and the gender choice in the electronic connector design!

Connector mechanical fastener gender

In the mechanical design of the connector, the prototype "convex" component is a threaded bolt, but the alignment post, mounting boss or sheet metal joint connector can also be considered convex. Accordingly, the nut, the alignment hole, the mounting groove or the metal plate slot connector are considered to be negative. While the mechanical design of some connectors is a "one-off" custom setup and is not intended to be repeated, the entire fastener industry is dedicated to manufacturing mass-produced or semi-custom components. To avoid unnecessary confusion, the traditional definition of fastener gender has been defined and agreed upon.

Gender selection in electronic connector design

Electronic connector designers often choose female jack connectors to be fixedly mounted on the electronics they design. This is usually because the female connector is more resistant to damage or contamination due to its hidden or recessed electrical contacts. Damaged motherboard connectors can result in the disposal of expensive electronic equipment. The risk of costly damage can be reduced by downgrading more exposed male contacts to the connecting cable, which can be repaired or replaced at a lower cost.

Board-to-board connector application requirements

According to the current status of the connector market, the development trend of the board-to-board connector is very rapid, and the application is more and more extensive. The design of the board-to-board connector is smaller, and the lighter and cheaper price drives the rapid development of the wireless device market. The application requirements for board-to-board connectors are also worthy of attention.

The scale of the board-to-board connector in the wireless device market will be smaller and the price will be lower. Reducing the size of the device means saving space, reducing weight, and leaving more room for other system designs. The size of the device is steadily decreasing, and the size of the integration and equipment required is getting smaller and smaller.

For example, it is widely used in distributed base station system RRH (Remote Radio Head), which can be easily, conveniently and reliably installed in the top of the tower and in dense urban environments. The design must be very compact and control the coaxial interconnection that requires RF signal transmission. The size of the system must be more compact. Traditional and complex cable assemblies are being replaced by board-to-board coaxial connectors that are simple, compact, reliable and capable of carrying more than 100W of RF signals.

Nowadays, connector designers are getting more and more understanding of the board, and the design technology is getting higher and higher. More and more, the board-type board-to-board connector is used, which allows designers to consider more design costs. And the demand for board-to-board connector solutions on the market is simple design and lower cost.

On the other hand, as connector sizes become smaller, mechanical structural design faces two major challenges. First, small-sized connectors are more difficult to align with each other than large-sized connectors. Second, the small size connector has low mechanical strength and can be easily damaged if used improperly. Typically, large connectors can withstand large mechanical forces during assembly without damage, but smaller connectors require more precision when used in combination.

Common wiring methods for the quick connectors

There are many factors to consider when designing a quick connector. The current load condition of the connector, the strength of the external relay, the durability of the life cycle used, and the safety performance standards are extremely important. In order to ensure the safety and quality of the quick connector. Work efficiency and quick connector wiring are extremely critical. The following sections describe some common quick connector wiring methods.

Quick connector twisted connection

Stranded connection refers to the direct twisting of the core wires to be connected to the wires. Generally, the copper wires are often connected by twisted wires, and the single-strand copper wires are directly connected.

When the small-section single-strand copper wire is connected, the core wires of the two wires are first X-shaped, and then they are wound for 2 to 3 turns, then the two wires are straightened, and then each wire is tight on the other core wire. After 5 to 6 turns around the tape, cut off the excess thread.

When connecting large-section single-strand copper wires, first fill a core wire of the same diameter at the overlap of the core wires of the two wires, and then tightly wrap a bare copper wire with a cross-section of about 1.5 mm2, and the winding length is a wire. 10 times the diameter, then the core wire ends of the connected wires are folded back, and the wound bare copper wires at both ends are further wound for 5-6 turns, and then the excess wire ends can be cut.

When connecting single-strand copper wires with different cross-sections, firstly wind the core wire of the thin wire tightly on the core wire of the thick wire for 5-6 turns, then fold the wire end of the thick wire core wire back to the wound layer, and then use the thin wire. After the core wire continues to be wound for 3 to 4 turns, the excess thread can be cut off.

Quick connector branch connection

The T-branch connection of the single-strand copper wire is to tightly wind the wire end of the branch core wire on the trunk core wire for 5 to 8 turns and then cut off the excess wire end. For the core wire with a small cross section, firstly, the wire core of the branch core wire is wound around the core wire of the trunk wire, and then the wire is tightly wound for 5 to 8 turns and the excess wire head is cut.

Quick connector short connection

When the short connection is made, the connector can be wired faster, pressed directly with pliers, and insulated, and can effectively prevent contact failure. Short-circuit screw cap can also short-circuit the wire, and the two wires Screw it on one piece and screw it on with a shorting screw cap. It is also very strong.

Of course, the quickest method is to open the connector wire head, screw the two wire ends together, and wrap the insulation tape. However, this method is too risky to be used as a bad contact, and the safety hazard is high. Tin on the root line, directly soldering the two wires with a soldering iron, is the safest method, but it is a bit of a hassle. Generally, the wiring is used for wiring, which not only improves safety, but also facilitates subsequent disassembly.

the performance characteristics of the shell type

There are many types of connectors, and different connector models have different sizes and shapes. Rectangular connectors are widely used in electronic devices such as computers, printers, stereos, and mobile phones. Everywhere, how much do you know about the performance characteristics of a rectangular connector? The following is a description of the performance characteristics of the shell type.

In addition, the rectangular connector also has a key component called an elastic contact wire. The structural quality of the elastic contact wire greatly affects the contact performance of the rectangular connector. Because if the elastic contact line has good elasticity and considerable impact resistance, it can greatly improve the efficiency of our work in the actual production and life, and ensure that the work is better and well-organized.

Rectangular connectors can be classified into the following types depending on the housing:

1. Aluminum cold machine shell: This kind of rectangular connector has a wide range of products. The common specifications are 9.15mm and 1.27mm pitch.

2. Full speed housing: The rectangular connector of this housing is also available in a variety of spacing options.

3. Extended shell: The rectangular connector of this kind of shell not only has a variety of specifications and spacing, but also can be developed according to the needs of customers, providing customers with considerable convenience.

Read more about the connectors(Four design ideas for connectors in harsh environments).

Four design ideas for connectors in harsh environments

The trend in connector technology is to require applications that can withstand harsh environments involving exposure to dust, splashing water or cleaning solutions over their useful life. They usually have a housing that protects internal components from risk. However, designing an application and selecting components that meet these criteria is often not easy. When choosing a connector, the designer must consider many factors such as temperature, humidity, solvents, icing, corrosion, fungi, salt exposure, and the like. Incorrect selection can affect the integrity, performance, and longevity of your application.

Connector communication protocol

One of the main considerations is determining the type of communication or using the application. Each connector can be used to carry different types of signals, such as RS232 or I2C serial interfaces, RF transmission, audio and video signals, power or high-speed data communication. In addition to this, the level of data rate and characteristics should also be considered. In some cases, a single connector can use more than one communication protocol. In terms of power requirements, designers must check voltage and current requirements. In addition, the selected connector should meet certain criteria to ensure it fits the desired application. Amphenol ICC offers a range of harsh environment connectors for a variety of applications.

Connector space requirements

This is the era of miniaturization, with all modern applications turning to chips and technology to provide advanced features in a small size. Design engineers should be cautious because they should choose the connector that fits the space they need. There are options such as nesting and linkage scheduling, or they can even combine functionality with a reduced number of interfaces. You can also look for designs that seal the connector into the panel or placed in front of or behind the enclosure.

Connector termination style

Once the communication protocol and connector form factor are fixed, we can consider the termination style. The harsh environmental connectors provide a metal seal and provide an electrical connection. This electrical connection is made by soldering the connector directly to the board or through a cable termination. If we choose to solder directly, we can choose a vertical or right angle PCB solder termination. In the case of cable termination, there are several options, such as solder cup termination, which is a popular choice. Crimp termination is another option and is usually labor intensive. Xinpengbo offers demanding connectors mounted on the interposer card, offering a wide range of termination types and great flexibility.

Connector EMI protection

In addition to water and dust, connectors in harsh environments should be able to protect components from electromagnetic interference (EMI) radiation. EMI radiation can enter the box and interfere with the function of the device or exit the box and interfere with other devices. To ensure the best EMI performance for connectors in harsh environments, choose a connector with an electroplated metal casing and conductive washers.

Talking about the influence of mobile phone industry in Taiwan connector manufacturer

In recent years, the connector industry has penetrated into the mobile phone manufacturing industry. It is believed that the industry is growing, market demand is gradually increasing, and the mobile phone industry is eager to become a market opportunity. Strictly speaking, Taiwan connector manufacturers entering the mobile phone connector manufacturing industry have become More disadvantageous to the advantage.

When comparing Taiwan's mobile phone industry with the personal computer industry, it is not difficult to see that Taiwan connector manufacturers have entered the mobile phone industry quite late, and the market has entered a mature stage. Due to the saturation of Taiwan's PC industry, most Taiwanese companies have poured into the mobile phone industry, which makes them vulnerable and inexperienced. It is not easy to enter the mobile phone industry at this time.

The mobile phone industry lacks an assembly market, and Taiwanese mobile phones are sold as products to end users, meaning that there is neither an assembly market nor production and processing capabilities. Compared with the PC industry, there is no pressure in building brand and retail systems. Small and medium-sized connector manufacturers can be boldly involved in operations, and the mobile phone industry clearly has greater obstacles in this regard. The lack of flexibility in parts and components is also a major drawback in the mobile phone industry. Mobile phone component manufacturers use different soldering techniques and splicing methods, and even solder the internal components of the phone, making maintenance very difficult.

In addition, the PC system is relatively independent and consists of many modular products, such as motherboards, expansion slots, etc., which are of a high standard. These components are flexible and have convenient benefits for connector manufacturers and consumers. Manufacturers can reasonably replace parts according to different consumer needs, and consumers can also obtain more reliable protection in product maintenance.

The inconsistency of the mobile phone architecture is the same as the inelasticity of the parts, and the mobile phone is a closed system. If the architecture is inconsistent, there is no single design, which poses a greater obstacle for Taiwan connector manufacturers. Early entry into the reserve price period has become a major challenge for product development. For the PC industry that has entered saturation, entering the low price period is necessary to ease the pressure, and the low price prompts the PC industry to re-examine itself and continue to develop and innovate.

However, for the increasingly mature mobile phone industry, low price is a kind of pressure. It will not only affect the external market, but also limit its own ability. For Taiwan connector manufacturers who have just joined the mobile phone industry, the trend of low prices is low. Not only is it synonymous with throwing wet blankets, but it can also lead to downfall. This is precisely because of the rapid development of the mobile phone industry, the competition in Taiwan and other regions has intensified, and it has brought enormous challenges to enterprises that are changing the mobile phone industry. To make enterprises gain advantages, it is not enough to obtain funds.

​How to design a safe auto connector

Connector, also known as plug in China, whice mainly used in electronic, electrical and other products, connectors are required in most industries. Divided by the application market of connectors, the largest connector application market lies in electrical, telecommunications, digital electronic products, followed by industrial automation equipment in automobiles and instruments, and finally in medical, aviation, railway, transportation, etc. Important on large equipment.

In our daily life, the car is very close to our lives. Car travel has become an important part of people's lives, and with the development of the traditional automobile industry, cars are one of the important reasons for climate warming and urban pollution. Also, due to the depletion of petroleum resources and the huge increase in oil prices, the automobile manufacturing industries in various countries are undergoing changes. Therefore, new energy vehicles with low emissions and low pollution have gradually become the mainstream development direction of the automobile market.

And because of the rise of hybrid and electric vehicles, automotive connectors have become a new hotspot for connector applications, so the difference between automotive connectors and common connectors is more focused on the safety of connector products, after all, this is directly related to Personal safety. In fact, not only the car, but for any device connection system, the key safety features of the connector are in the first place. Therefore, in some fields that have higher requirements on safety performance, such as medical electronics, testing instruments, industrial automation, electronic communication and other industries, the first choice of connectors must be considered for their safety performance, thus ensuring the connection service. The safety and reliability of the connector products have a greater significance.

The necessary way for connector manufacturers to develop correctly

Connectors are not emerging industries, but they are growing steadily. Due to its stable market and relatively small risks, more and more people are joining the connector manufacturing industry, which undoubtedly increases competition among connector manufacturers. Nonetheless, as a connector supplier, the following guidelines must be followed to ensure the right path to development and success.

First, connector manufacturers need to be aware that there are still some fluctuations in even the most stable market. For example, connector production declined a few years ago. At that time, many people were involved in the production of connectors, but the number was quite large, and there was no innovation in technology, so demand fell. However, many manufacturers quickly adjusted their business plans. Some people added technical content to their connector products, while others chose to make custom connectors for electronics companies. In general, everyone has a solution to the crisis.

In addition, connector manufacturers can not only follow the development pace and path of others, but should develop their own unique product features. As far as connector technology is concerned, it is not particularly complicated, and many connector vendors do not have significant differences in the technical aspects of the business. Therefore, everyone needs to compete in other areas to find another “spring” for their connector business. For example, in the case of electronic products with a focus on sales plans, it is obviously key to strengthen their own hardware. What is hardware? Hardware is a component that increases the value of a connector. The functionality of the connector does not change, but is only enhanced, that is, just changing a material or adding a small portion to convert and enhance the functionality of the hardware.

Finally, as a connector manufacturer, it must have ambitious development goals. Although the connector seems to be a very simple component, it is indispensable in many fields. Therefore, regardless of the current market situation, connector manufacturers should be full of confidence. In addition, the connector market is also very important, that is to say, some large companies already have their own exclusive market. If you try to compete with them as a new connector manufacturer, it is undoubtedly very difficult. Therefore, the focus is to pay more attention to the continuous expansion of the market, to find new markets, and to avoid competition with large connector manufacturers.

The function properties of USB connector

Holding power

Unlike other older connectors, the USB is held in place on the peripherals and cables by the clamping force from the socket. There is no thumb rotation, screw or clip to keep it in place.

durability

The USB has an improved design that is more rugged and durable than previous connectors. This is because it is hot-swappable and this property allows the USB connector to be added to a running computer system without significantly interrupting the operation (ie, shutting down or restarting the computer).

Service life

To extend the life of standard USB, designers have modified their designs. Move from the jack, the leaf spring to the plug. A locking device is also added to keep the connector in place. With these improvements, standard USB can now withstand up to 1,500 repetitive insertions and removals. On the other hand, the Mini B connector can last up to 5,000 insertion and removal cycles after further improvements.

Micro connectors have proven to be the most durable. They are designed to withstand up to 10,000 repetitive insertions and removals. To achieve this goal, a flexible contact is mounted on an easily replaceable cable, and on the other hand, the container is a container that houses a more durable rigid contact.

Protection performance

A closer look at the USB connector reveals that the adjacent plastic tongue and another closed metal plate protect the entire connection assembly and provide additional protection for the USB. In addition to this, the USB plug also has a housing that first contacts the socket before it is connected to the host. In order to shield the wires inside the connector, the case is grounded, which also helps to eliminate static electricity.

Length limit

Although USB has these positive features and enhancements, the functionality of this data transfer interface still has limitations. First, the USB cable cannot connect peripherals and computers that are more than 5 meters (or 16 feet 5 inches). USB connectors are limited in length because they are designed to connect devices on a single desktop, not devices or structures between rooms. However, this can be solved by using a self-powered USB hub or an active (repeater) cable. The length of the USB cable can also be extended by using USB over Ethernet or by building a USB bridge.

The connector manufacturers' market trends

Connector manufacturers from China and Taiwan occupy almost the dominant position in the Asian connector market. In recent years, multimedia and AV connectors have driven the connector market, resulting in a rapid increase in connector production. In addition, connector suppliers in China and Taiwan have increased their investment in production and technology innovation, and have further expanded their connector applications, focusing on the integration of new connectors and multi-device interfaces. However, the market development trend of connector manufacturers in China and Taiwan varies from region to region.

China has already controlled the low-end connector market, however, it has gradually entered the mid-range market and carried out technological reforms to increase its competitiveness in Asia while ensuring quality and lowering prices. China Electronics Components Association Connector Branch estimates that global demand for connectors will reach 33%, an increase of 5% year-on-year. The significant development of connectors is closely related to the increase in electronic devices in China. The vast market for mainstream Chinese computers, telecommunications and fiber optic models has also contributed to the simultaneous development of the connector industry. Currently, China has a full range of connectors.

The connector industry is one of Taiwan's major industries. According to the report of the Taiwan Industrial Technology Research Institute, the total output value of connectors reached 3.7 billion US dollars in 2006, an annual increase of 500 million US dollars, which played an important role in Taiwan's economic development. . At present, Taiwan's connector manufacturers focus on developing and manufacturing high-end products such as RF, HDMI and memory cards. They choose to produce low-end connectors in factories in China, and carry out strict product testing and quality control processes different from China. In addition, many major Taiwanese companies have invested heavily in test equipment and even used the same method to maintain RoHS-compliant equipment. As a result, Taiwan connector suppliers have obtained international quality certification, and their brands are recognized worldwide. They are able to gain market share.
