Cars have a huge demand for cable

The variation in automotive wiring harnesses is extremely vast; it’s not just the low cost, the heavy duty, or the luxury platforms. There are certainly optimized architectures, and especially for cost and weight. The sheer physical limitation of packaging space and volume demands the latter. But many different architectures have arisen to meet the needs of individual vehicle designs and are going to continue to evolve as automobiles continue to leverage new, next-generation technologies. For example, autonomous vehicles will have to implement centralized data storage and scalable, modular system architectures, and the wiring and networking components will have to evolve to support them. The question is whether the solution to next-generation wiring challenges is optical or wireless instead of just copper. There are a huge variety of parameters that will factor into these decisions, extending from vehicle’s network and software considerations to their physical wiring and electrical performance specifications.

Right now, there is a big push toward automotive Ethernet. Ethernet solves a lot of problems in terms of speed and reliability, but it hasn’t kept up with vehicle’s high-speed network needs. In addition, the Ethernet route also won’t offer standardized products that OEMs can employ as one-size-fits-all solutions. There are sure to be some standard CAN, LIN, and Ethernet approaches, but on top of that there are always going to be proprietary and application-specific protocols because they are technically required. So, there is still no real standardized answer for OEMs to fall back on there.

In the past, if you added a feature like power windows to a vehicle, you also added a power window module to its wiring harness. When you look at the current architectural approach, engineers now have to implement functions such as “window up.” Today’s automotive engineers have to account for features that can be implemented with a soft switch on the center console, a hard switch on the door, or even voice activation. This means that more features have to be implemented using software solutions, which should support more standardized automotive architectures for individual OEMs. This approach to automotive architectures will also result in more component reuse, which will mean fewer but larger component applications with redundant software modules and even more diagnostics.

As vehicles become more software-driven, there will be a greater need for diagnostics that can help ensure the functional performance of critical systems. Connector and header products will require finer-pitch data and power communications, back-up or fail-safe mechanisms, and robust diagnostic capabilities, in addition to an ever-expanding suite of core functionality.

The benefits of GPS to the car

The use of satellites for navigation becomes more and more popular among car owners, and those who have big automobile businesses. The statistics shows that the market grows constantly, in the United States the GPS equipment sales in the commercial segment amounted to 1.909 million units in 2005, and in 2010 7.74 million devices were sold.

Usually vehicle GPS tracking system is complemented by the features of anti-theft system. When user receives an alarm, he can remotely send a command to the GPS receiver (built-in auto unit) — to turn off the engine or to turn on the siren. As we see this monitoring system is fully justified.

It looks like there is only one “con”, which GPS navigation system has — it uses GSM technology. If there is no connection then for a period of time car control will be lost. But, even when GSM connection is unavailable, all information will be saved on the memory of the GPS electronic unit. As a result, after signal restoration device will operate in a normal mode.

GPS system that is placed on a vehicle must consistently and reliably transmit all the information to carry out GPS monitoring process. Here are some benefits that company can get from using a GPS system:

Reducing the repair expenditures;

Slowing the depreciation processes;

Increasing the cargo volume due to reducing of a fuel consumption costs;

Increasing the responsibility of the employees;

Rapid response to various abnormal situations;

Reducing the cost of communication model “driver–company”.

So I think many car companies will choose to install a GPS, which will make their car better. Our yeahui Electronics Co., Ltd. is a manufacturer of connectors and cables. With 11 years of history and a team of professionals, we can manufacture the connectors needed to install GPS. Of course, I can also manufacture obd connectors, circular connector, marine connector and others. We can also provide customized services to provide different types of connectors according to your needs.

Why connectors have advantages over hardwiring

Nowadays most people like to use connectors instead of hard wires, so why is this happening? What are the advantages of connectors?

1. Installation time

Hardwired control cabinets in a row or larger switchgears must be disassembled to transportable sizes before they can be sent out to customers in the supply chain or directly to the construction sites. For re-assembling, customers tend to hire electricians or subcontractors who are often less familiar with the equipment itself and the special tools than the original manufacturer’s teams. This can eventually lead to failed on-site tests and lengthy re-evaluation processes.

2. Labor Costs

Hardwiring often leads to extra labor costs. The assembling, testing and repair of components takes a lot of time and efforts, requiring staff with special skills. The use of connectors dramatically reduces costs, since it increases efficiency and allows for savings of time and labor.

3. Maintenance

Using connectors instead of hardwiring, power generation and transmission facilities and their subsystems are easier to maintain. In the field, the service teams simply have to uncouple parts from the applications and replace them by pretested new ones.

4. Design and lead time

Using modules, power, control, and data transmission can take place side-by-side in one connector. The related contacts and inserts are designed for high-voltage/current, thermocouple, Profibus or Ethernet transmission. The modular principle increases the flexibility and saves space on the equipment, making it much easier for specialists to design the applications in the grid according to the latest technologies and trends, such as digitalization, modularization or miniaturization.

How to place the cable reasonably in a car

With the safety of modern vehicles, the increasing requirements for comfort and environmental protection, the number of circuits and the amount of electricity used in automobiles have increased significantly. How to properly place a large number of wire harnesses in a limited car space has become a problem in the automobile manufacturing industry.

According to the actual installation position of the wire harness on the whole vehicle, in order to avoid the drop and displacement of the wire harness, considering the weight of the wire harness, the fixing method and the convenience of the fixed position, the wire harness must have sufficient and reasonable fixing points and fixed manners for fixing.

According to the direction of the wire harness and the specific shape of the vehicle body, a fixed point is set. The distance between the two fixed points is generally not more than 300 mm in the straight line distance without the fulcrum; a fixed point can be arranged at the inflection point of the obtuse angle; two fixed points are arranged at the right angle turning point; the acute angle The inflection point is avoided in the bundle.

According to the shape and outer diameter of the wire harness, the type and size of the fixed buckle are selected, and the need to bear the weight of the wire harness is satisfied.

In the position of the connector connected to other harnesses and electrical components, a suitable fixed point is considered in a suitable position of no more than 120 mm in front of the connector.

Consider setting a fixed point on the main line at the fulcrum position. The fixed point distance is not more than 100mm.

In the installation direction of the fixed buckle, there must be enough space to facilitate the installation and removal of the buckle.

What are the wire harness welding steps

Generally, the main wire is welded or straight welded during the welding process. What are the wire harness welding steps?

The wire processing factory generally adopts the soldering welding method, the right hand holding the iron iron, and the left hand holding the solder wire, the operation steps are as follows:

1. Stripping: Stripping with wire stripper should pay attention to the single wire should not hurt the wire, multistranded wire and shield wire, otherwise it will affect the quality of the joint, pay attention to the wire core when peeling the multi-strand wire Spiral. The stripping length is operated according to the process data requirements.

2. Pre-welding: Pre-welding is a key step in wire bonding. When the wire is hung, it should be rotated on the side of the tin. The direction of rotation is the same as the direction of screwing. For the stranded wire, pay attention to the “wicking effect”, that is, the solder enters the insulating layer. Inside, the cord becomes hard and easily causes joint failure.

3. Heating: First heat the component leads and pads with the preheated Lotte head.

4. Wire feeding: Hold the tin wire left and right and send it to the welded part that has been heated.

5. Leaving: After the solder wire melts and flows slowly to two-thirds of the area of ​​the pad, the solder wire and the iron head are quickly removed.

6. Solidification: After the anti-evacuation of the iron head, do not shake the components and the circuit board. The solder joint should be naturally solidified. For the components that are easily burnt, the welding can be blown to accelerate the solidification.

7. Inspection: Check the welding quality, require a moderate amount of solder joints, smooth solder joints, and firm soldering.

Electric vehicle cable standard

Now that the new energy vehicle market is developing rapidly, there will be a series of problems. To put it simply, new energy vehicles mainly refer to the use of unconventional vehicle fuel as a power source, integrated vehicle power control and drive technology, and the formation of advanced technology, new technology, new structure of the car. Mainly include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, and other new energy vehicles.

Electric vehicle cable standard

But no matter what the form of new energy vehicles is, their common feature is to use voltage platforms up to 300V~600V or higher, and they all have the same basic requirements, that is, the safe transmission under the electromagnetic interference protection system is high. Current and voltage. The high-voltage cable is used to connect high-voltage batteries, inverters, air-conditioning compressors, three-phase generators and electric motors to achieve the transmission of power and power. However, it should be noted that the high-voltage harness of an electric vehicle is not equivalent to the high-voltage power transmission cable in our daily life, but is relatively relative to the low-voltage system of a conventional automobile.

why overvoltage protection remains a consistent requirement

High reliability is paramount in our always on, hyper-connected world. Application downtime or failure runs the gamut from frustrating to incredibly expensive. That is why overvoltage protection remains a consistent requirement. Users expect seamless system operation so guarding them against unstable electrical service swells, switching, and lightning voltage transients just makes sense.

In the overvoltage protection component arsenal, Metal Oxide Varistors or MOVs are popular solutions. New MOVs boast high current handling, high current absorption, and fast reaction time to protect against transient faults up to their rated limits. Power supplies, power systems, line voltage, telecom systems, white goods, and appliances are among the applications using MOVs for protection. Unfortunately, they are susceptible to degradation and failure issues in certain harsh and uncontrolled environment applications. These problems are well-documented, and UL requires extensive testing to guard against harmful failure modes. An MOV failure can occur from a thermal runaway condition, which defines the lifespan of an MOV. Thermal runaway conditions could also increase the risk of fire in an MOV, prompting designs to typically require additional thermal cutoff or fusing devices for safety.

What Is Safety Behavioral Data and What Does It Measure

Bad driving habits, such as speeding, sharp turns, quick lane changes, and hard braking can result in serious crashes, which, in turn, can result in injury, liability costs and even loss of business. The cost of crash reports, litigation and loss of productivity is usually 3–5 times more expensive than the direct costs of the accident. That is why the ability to track trips and activity by vehicle and by driver is so valuable. It identifies drivers who aren’t safe or careful with their vehicles and works to prevent accidents using special driver coaching programs or apps.

Driver behavior apps are based on GPS monitoring data and are fleet managers’ eyes and ears in any vehicle in the fleet. Driver behavior software tracks fleet components by driver IDs and tracks aggressive driving behaviors, such as speeding, stop sign violations, harsh accelerations, cornering and braking, and more. Fleet managers can view the data on demand using dashboards, identify bad drivers, and create driver safety profiles for each of driver in a fleet.

Some systems include driver toolkits with driver feedback tools, such as sound alerts in case of the likelihood of an accident. The collected data can be used by managers to create driver-specific training sessions so drivers can re-learn safe driving techniques and quickly correct bad habits. Such coaching can minimize fleet costs related to both insurance premiums and accident claims as safer driving habits minimize the risk of collisions. Some systems can identify drivers that need training based on vehicle analytics and measure their compliance with the company’s safety goals.

Most of the systems on the car are dependent, they use the connector as a conductor to pass data. Therefore, the connector is also a relatively important component, and a car needs a lot of connectors. If there is a problem with the connector, it is very unsafe for us to drive. So choosing a high quality connector is also very important.

Read more about the connectors(Talking about FPC connectors).

Talking about FPC connectors

FPC connectors are characterized by high cable density, light weight and thinness, so they are called flexible circuit boards, flexible printed circuit boards or flexible circuit boards. Most FPC connectors are made of polyimide (PI) or polyethylene terephthalate (PET), which improves the reliability of FPC connectors.

FPC connectors will vary depending on how the raw materials and copper cladding are connected. Therefore, FPC can be divided into two main types: 3-layer FCCL and 2-layer FCCL.

The 2-layer FCCL has greater flexibility, and the raw material 2-layer FCCL is too expensive to use on the market. In contrast, the 3-layer FCCL is much cheaper and is usually used on the market. However, the flexibility and flatness parameters of the mat are not as good as the 2-layer FCCL, so there may be welding defects such as cracks, which manufacturers should try to avoid.

Since 3-layer FCCL is more prevalent in the market, more and more connector manufacturers adopt it and it is better developed. Different types of FCCL can be classified according to the number of layers of copper foil, including multi-layer boards, double-layer boards, single-layer boards and double-layer boards.

The single layer board has the simplest structure. Connector manufacturers typically use structures that include raw materials, clear plastics, and copper foil. Some FPC connector manufacturers use a layer of protective plastic and transparent plastic. This structure can greatly improve the mechanical strength of the 3-layer FCCL.

The two-layer structure is used for complex circuits that cannot be wired or shielded. The multi-layer board is different from the single-layer board in the VIA structure, and can effectively connect different layers of copper foil. Double-sided two-sided soldering, mainly used to connect other boards. In addition, the FPC connector can be applied to MP3 and MP4 players, digital cameras, mobile phones and mobile phone batteries, and the future development of FPC connectors is very good.

Automotive connector knowledge sharing

Automotive connectors are widely used in various places and systems of automotive, as a function of connecting and disconnecting current. Since there are many types of automotive connectors, it is hard to remember, so it is very important to choose a suitable automotive connector. of.

The automotive connectors have different classification methods, and we can divide them into high frequency connectors and low frequency connectors if we divide them according to the frequency they send.

When we buy an automotive connector, the electrical parameters of the automotive connector are the first to look at, and the most important one is the rated voltage of the automotive connector. The rated voltage is also called the operating voltage. It depends mainly on the connector. The amount of insulation used between the insulating material and the contact pair. Some components or devices may not perform their intended function below their rated voltage, so for the normal use of the automotive connector, regular maintenance and care must be performed.

The automotive connector is used in many electronic engineering applications. With the increasing use of automotive, there is a growing demand for some automotive devices. The most important component of an automotive connector is its contact, which is a core component of the connection system.

How to improve the reliability of the connector

Electronic connectors are widely used in power system equipment, and are on the rise with the increasing popularity of electronic technology.

Electronic connector division can be divided into aviation, automobile, military, household appliances, etc. according to common fields. For example, according to the external structure, it can be divided into pin header, circle, rectangle and so on. But from a technical point of view, to make the application of technology more effective and in-depth.

The reliability of automotive connectors is unquestionable. The ambient temperature is greater than conventional, corrosive, vibration and frictional wear, so the reliability of the factors is worse than the conventional environment.

For contact force design of electronic connectors, there are two common guidelines for smaller force design guidelines (for small currents) and larger contact resistance design guidelines (for larger currents.)

For corrosion factors and reliability factors, connector manufacturers will rigorously test new products before they can be mass-produced and marketed in their application fields.

Read more about the connectors(Basic performance of the connector).

Basic performance of the connector

The basic performance of connectors can be divided into three categories: mechanical, electrical, and environmental.

Mechanical behavior

Mechanical properties In terms of the connection function, the insertion force is an important mechanical property. The insertion force is divided into the insertion force and the extraction force (the extraction force is also called the separation force), and the requirements of the two are different. There are maximum insertion force and minimum separation force regulations in the relevant standards, which indicates that the insertion force is small from the point of view of use (thereby having a low insertion force LIF and a structure without ZIF insertion), and if the separation force is too small, It will affect the reliability of the contact.

Another important mechanical property is the mechanical life of the connector. Mechanical life is actually an indicator of durability, which is called mechanical operation in GB5095. It takes one insertion and one extraction as one cycle to judge whether the connector can complete its connection function (such as contact resistance value) after the specified insertion and removal cycle. The insertion force and mechanical life of the connector are related to the plating quality (sliding friction coefficient) of the contact structure (positive pressure) contact portion and the dimensional accuracy (alignment) of the contact arrangement.

Electrical performance

The main electrical properties of electrical performance connectors include contact resistance, insulation resistance and electrical strength.

1 Contact resistance High quality electrical connectors should have low and stable contact resistance. The contact resistance of the connector ranges from a few milliohms to tens of milliohms.

2 Insulation resistance is an indicator of the insulation performance between electrical connector contacts and between the contacts and the casing, in the order of hundreds of megaohms to several gigaohms.

3 Resistance to electric strength, or withstand voltage, dielectric withstand voltage, is the ability to characterize the rated test voltage between connector contacts or between contacts and housing.

Environmental performance

Environmental performance Common environmental properties include temperature resistance, moisture resistance, salt spray resistance, vibration and shock.

Overview of Military Standards for RF Cables and Connectors

Many coaxial cable and connector types are available in the RF and microwave industry designed for specific purposes and applications; compatibility with other RF microwave components is achieved with universally accepted cable and connector standards. The US Department of Defense (DOD) develops standards for materials, facilities, engineering, and testing practices in order to improve military operational readiness and reduce costs and production time. DOD standards have adopted non-government standards and practices that meet DoD performance requirements. This process is managed by the Defense Standardization Program who provides the standards and relevant specifications. RF cables and connectors used in military applications have demanding requirements for environmental specifications, such as temperature, shock, and vibration; these requirements are specified in detail the US Department of Defense military standards in MIL-DTL-17J for coaxial cables and MIL-PRF-39012 RF for coaxial connectors.

Department of Defense Standards (DoD)

The Acquisition Streamlining and Standardization Information System (ASSIST) database is a list of defense and federal standardization documents as well as adopted non-government standards (NGS), and Materiel International Standardization Agreements (ISAs).

MIL-DTL-17

Coaxial cables for military and aerospace applications must meet the standards and specifications in MIL-DTL-17 which details specifications for flexible and semi-rigid coaxial cables with solid and semisolid dielectric cores as well as single, dual, twin, and triaxial conductors intended for use in radio frequency applications.

Read more about the connectors(What is the use of automotive connectors).

Common faults in automotive connectors

The automotive connector consists of contacts, housings, insulators, and other accessories that act as bridges in the car’s wiring to allow the vehicle’s internal circuitry to circulate. Once a problem occurs inside the connector, the overall line is not circulated. Therefore, the connector manufacturer recommends that corrections be made in time if problems are found.

Common automotive connector problems can be divided into the following points:

1. Problems with the connector material of the car connector. The raw materials of the automotive connector connector can affect the performance and other unstable performance. Therefore, if the automotive connector material purchased at the time of purchase is inferior, the connector is prone to problems when it is used.

2. The current and voltage of the automotive connector circuit are unstable. Current and voltage problems are external factors that can be stabilized by installing products such as voltage regulators.

3. The car connector is not used within the regulations. Automotive connector products have their own environment, such as the general heat resistance between 40 ~ 120 ° C, the insertion force is below 20.5 kg. Once the operating conditions are out of the rated range, it is easy to cause problems with the connector.
