The fixed design of automobile wiring harness is a very important item in the design of wiring harness layout, and its main forms are auto cable ties, buckles, and brackets.

Ⅰ. The role of automotive cable ties

Automotive cable ties are the most used wire harness fixing and protective materials, mainly made of PA66. Most of the fixing of automobile wire harnesses is done with cable ties. The function of the automotive cable tie is to fasten the wire harness and make it firmly and reliably fixed on the body sheet metal holes, bolts, steel plates and other parts to prevent the wire harness from vibration, displacement or interference with other parts and damage the wire harness.

Ⅱ. The classification of automotive cable ties

Although there are many types of cable ties, they can be divided into the following types according to the type of sheet metal: card round hole type cable tie, card waist round hole type cable tie, card bolt type cable tie, card steel plate type cable tie, etc.

1. The round hole type cable tie is mostly used in places where the sheet metal is relatively flat and the wiring space is large and the wiring harness is smoothly routed, such as the cab, the diameter of the round hole is generally 5-8 mm.

The card-waist round-hole cable tie is mostly used for the thick trunk or branch of the wire harness. After installation, this cable tie cannot be rotated at will, and has strong fixed stability. It is mostly used in the front compartment. The aperture is generally 12×6 mm, 12× 7 mm)

2. Bolt-type cable ties are mostly used in places where the sheet metal is thick or where the uneven wiring harnesses are irregular, such as firewalls. The apertures are generally 5mm or 6 mm.

3.The steel plate type cable tie is mainly used on the edge of the steel sheet metal to jam the sheet metal, so that the wire harness transitions smoothly, and at the same time, to prevent the sheet metal edge from piercing the wire harness. It is mostly used in the wiring harness and the rear bumper in the cab. The thickness of gold is generally 0.8~2.0mm.

Analysis of the Causes of Pin Retraction of Automotive Wiring Harness Connector Terminals(2021年11月27日)

langrunconnector — 2021-11-27T15:19:12+0900

https://www.langrunconnector.com/automotive-connector/

Automotive wiring harness connectors are used to connect the connection points of automotive circuits, which are important parts of automobiles. Their quality directly affects the transmission effect of power or signals. Connectors account for a small proportion of the cost in automobiles, but if quality problems occur in automobile use, serious consequences will often occur, and maintenance costs will increase significantly. Therefore, the quality of connectors requires more attention by automobile manufacturers and auto parts suppliers.

1. The invalidation of automotive wiring harness connector terminal
The pin retraction of automotive wiring harness connector terminal is a relatively common failure form of automotive wiring harness connectors. It means that after the connector is assembled, the terminal and the sheath are abnormally separated, thereby causing the connector to lose its function. The reasons for this failure form generally include three aspects: ①The retention of the terminal in the sheath is unqualified; ②Interference in terminal of plug-in connectors; ③Product application problems. According to these three reasons, automotive connector supplier LR analyzes the pin withdrawal of the connector terminal and proposes a solution.

2. Analysis of the causes of pin retraction of automotive wiring harness connector terminals

(1) The retention of the terminal in the sheath is unqualified

The retention of the terminal in the sheath refers to the force required to separate the terminal from the sheath in the axial direction. In order to avoid the phenomenon of terminal withdrawal, the performance test standard of the connector sets strict regulations on the retention force of the terminal in the sheath: ①The retention of the connector with a specification not greater than 2.8 is greater than 40N; ②The retention of connector with a specification greater than 2.8 is greater than 60N. In practice, most of the phenomenon of terminal withdrawal is because the retention does not meet the requirements. Generally speaking, the reasons for the unqualified retention of the terminal in the sheath are: structural design problems; material selection problems.

(2) Interference in terminal of plug-in connectors

Interference in terminal of plug-in connectors means that the male terminal and the female terminal of the connector are inserted into the ineffective area of the female terminal during the mating process, so that the connector has a failure form such as terminal withdrawal. Generally speaking, the reasons for this are: ①Structural design problem; ②Terminal insertion force problem.

(3) Product application

The product application related to the return of connector terminals mainly refer to the problem that may cause the withdrawal of the terminals during the wiring harness production process. Generally include terminal crimping problems and terminal assembly problems. It is mainly caused by improper use method during product use. After adjusting the terminal crimping, this problem can be solved.

Introduction of the Types and Selection Principles of Automotive Wiring Harness Terminals(2021年11月27日)

langrunconnector — 2021-11-27T15:18:47+0900

https://www.langrunconnector.com/products/automotive-connector-terminal/

1. Types of automotive wiring harness terminal

According to the shape, the terminals can be divided into slice series, cylindrical series, and wire connector series.

1) The slice series terminals are made of H65Y or H70Y material, and the material thickness is 0.3-0.5.

2) Cylindrical series terminals are made of H65Y or Qsn6.5-0.1 material, and the material thickness is 0.3-0.4.

3) Wire automotive connector terminal is divided into three types: U-shaped, fork-shaped and hole-shaped.

① The U-shaped terminal is made of H62Y2, H65Y, H68Y or Qsn6.5-0.1 material, and the material thickness is 0.4～0.6;

②Fork-shaped terminals are also called Y-type terminals. Y-type terminals are made of H62Y2 with a thickness of 0.4-0.6. Part of the surface is nickel-plated with good conductivity;

③ Hole terminals generally use H65Y and H65Y2 as the base material, and the material thickness is 0.5 to 1.0.

2. Selection principle of automotive wiring harness terminal

It needs to choose terminals with different coatings according to different connectors and different needs. For equipment that requires high performance, such as airbags, ABS, car ECU connector, terminals should be gold-plated to ensure safety and reliability. However, for cost considerations, partial gold-plating can be selected on the premise of meeting performance requirements.

The specific selection principles are:

① Ensure that the terminals are reasonably matched with the selected connectors.

②Choose the appropriate terminal for the wire diameter of the crimped wire.

③For single-hole waterproof connectors, choose a terminal whose tail can crimp the waterproof plug.

④Ensure the reliability of the connection. When selecting automobile wiring harness terminals, ensure good contact with electrical components and plug-ins, so as to minimize contact resistance and improve reliability. For example, surface contact is better than point contact, and pinhole type is better than leaf spring type. In the design, the connector with double spring compression structure (with very low contact resistance) should be preferred.

⑤ Impedance matching. Some signals have impedance matching requirements, especially radio frequency signals, which have stricter requirements for impedance matching. When the impedance is not matched, signal reflection will be caused, which will affect signal transmission. Therefore, when selecting automotive wiring harness terminals, you must choose impedance-matched terminals.

The Use and Performance of Automotive Connectors(2021年11月27日)

langrunconnector — 2021-11-27T15:18:22+0900

https://www.langrunconnector.com/automotive-audio-connector.html

Automotive electrical connections are widely used in every parts of the car. Use with wiring harness, they are able to offer the connection solution between each component with the car well and safe.

Automotive connectors are an indispensable and particularly important part of both traditional and new energy vehicles. This is because the entire interior of the car plays a relevant and important role. So let's talk about the role and performance of automotive connectors.

1. Car connector plays a role in ensuring car safety

For automotive connectors, since many parts are related to safety, it is very important to select automotive connectors. Among those different car connector types, the part of the connector near the engine should have a temperature resistance of 150℃ or higher, and the other connectors should withstand a temperature of 105℃ or 85℃. Therefore, the temperature resistance of car connectors is higher than that of ordinary connectors.

2. The performance of the car connector during use

The harsh environment of the car during driving will affect the use of the product. For example, the line is short-circuited after the car is washed, or the camera is blurred, etc. This is because the connector is not waterproof. In order to avoid the impact on safety and performance, the waterproof of the car connector is another important performance, which means waterproof automotive connectors are required. Between the male connector and the device, between the female connector and the cable, between the male connector and the cable, and between the female connector and the cable, the four types of connections need to be waterproofed. The international automotive connector waterproof standard is IP67, which is also the industry's waterproof standard. According to different car parts, there will be different waterproof requirements. There are three main types of waterproofing for automotive connectors:

(1) Structural waterproofing;
(2)Sealing ring (silicone ring) for waterproofing;
(3) Use waterproof glue for waterproofing.

In order to ensure that the electronic circuit technology can work better, car connectors are generally designed for shielding. The function of shielding can firstly protect the electronic circuit of the car, and secondly, it also has the effect of anti-interference and radiation on other parts. The shielding technology is divided into two types: inner shielding and outer shielding. The inner shield is to shield the influence of the radiation generated by itself on other parts; while the outer shield is to prevent the radiation interference of other parts from affecting its performance.

Generally, there are corrugated pipes, PVC tubes, sponges, tapes, etc. on the outside of automobile wiring harnesses for wrapping and protection. For the entire automobile wiring harness assembly, different types of via rubber parts, cable ties, wiring harness buckles, wiring harness brackets and tapes are needed to limit the relative position of wiring harness products. Since automotive wiring harness products are generally supplied to the automaker in the form of assembly supply, this article mainly introduces fixed protection parts from the perspective of fixed protection of automotive wiring harnesses.

The following is various types of automotive cable ties and their use environment and application examples.

1. Ordinary plastic cable tie

According to different structures, there are two types: one-piece type and split type with movable fixed end. Ordinary cable ties are used in places where the wiring harness and pipeline have no specific location requirements relative to the vehicle and the space is relatively open. If you want to limit the position of the wire harness assembly, you need to use it with a fixed bracket or with various types of cable tie connectors.

2. Screw-fixed plastic cable tie

This type of cable tie is mainly used in areas where holes cannot be opened to strictly prevent rain, dust, etc. from entering the passenger compartment. Used in conjunction with bolts or screws, the general specification of screws is M5～M8.

3. Arrowhead mount cable tie for round hole

This type of cable tie is used with round holes. The hole diameter is generally φ5～φ8 mm. The disk at the end of the arrow can play a role in dust prevention. Arrow ties can only be used for single-layer boards, and the board thickness is usually less than 3 mm, which is different from the elliptical hole fixed plastic ties. This type of plastic ties allows the wire harness to be twisted after installation, and is mostly used for flat metal sheets, and used in places where the wiring space is large and the wiring harness direction is relatively gentle.

4. Arrowhead mount cable tie for oval hole

This type of plastic cable tie can prevent the wire bundle from twisting after the installation is completed. It has a better effect on the environment where the direction of the wire harness needs to be strictly limited, and has a strong fixing stability after the installation is completed.

Application and Principle of Automobile Nylon Cable Ties(2021年)

Langrun, founded in 2009, is located in Yueqing City, Zhejiang province, an economically developed city. We are a professional car electrical connections manufacturer integrating mold development, production and sales. It provide wire housing connector, pin housing connector, car connector,etc. We have types of car audio connectors, car audio wire connectors, best connectors for car wiring, hid ballast connector and so on.

1. Application of automobile nylon cable ties
With the rapid development of the automobile industry, the speed of automobile production is very alarming. Generally, there are many automobile wiring harnesses in the interior of the car. The automobile wiring harness is equivalent to the neural network of the automobile used to convey various instruction information and telecommunication signals, so that the whole vehicle is in a better control and running state. However, the existing automobile wiring harnesses are scattered in the interior of the automobile, and it is difficult to assemble the scattered wiring harnesses together, but the stability after assembly is not high and it is prone to failure.

2. The use of car nylon cable ties
These wiring harnesses are fixed on the automobile sheet metal by auto harness, and the safety and reliability of the wiring harness fixing is very important to the electrical safety of the whole vehicle. With the increase of vehicle engine functions, the wiring in the car cab and the engine need to communicate in real time, and more and more wiring harnesses need to be connected to the engine. The engine is a vibrating part, and the vehicle body also vibrates, so the wiring harness arranged on the car will also vibrate, which requires special attention by nylon cable tie manufacturer. Therefore, the fixing stability of the wire harness depends not only on the ability of the wire tie to fix the wire harness, but also on the stability of the wire tie on the vehicle body. However, the connection structure of the traditional automobile wire harness tie and the body is too simple, and the tie is easy to loosen, which causes the wiring harness and the nylon cable tie to shake as a whole, which seriously affects the stability of the wiring harness fixing.

In response to the above-mentioned shortcomings, a new type of automotive wire tie has been developed, which not only improves the stability of the wire tie on the car body, but also has no looseness between the wire tie and the car body, reducing the sway of the wire tie relative to the car body, ensuring the stability of the wiring harness, and improving the flexibility of the connection.

Contact resistance will affect the service life of car connectors, so today we are going to look at what factors can affect the contact resistance of the automotive connector terminal.

1. Influence of terminal materials

Different terminal materials have different hardness and conductivity. According to the analysis of action principle of contact resistance, different hardness results in different actual contact areas of each contact point on the terminal contact interface, thus resulting in the different actual total contact areas of terminal contact interface. The effect of the actual contact area on the additional resistance at the contact interface is equivalent to the effect of the conductor sectional area on the conductor resistance. Therefore, the additional resistance of terminal contact interface will be influenced by different hardness of terminal materials. To go further, different conductivity directly affects the resistance of the terminal contact area.

When it comes to automotive connector terminal options, materials with appropriate conductivity and hardness should be selected in accordance with the design targets. Meanwhile, the material with stable electrical conductivity and mechanical properties is worth considering to ensure the stability of contact resistance.

2. Influence of terminal contact interface geometric shape

The effect of terminal contact interface geometric shape on contact resistance is mainly due to the fact that different geometric shapes will form different macroscopic contact areas. The difference of macroscopic contact areas results in different number of contact points, which causes the difference of the actual contact area.
In practice, different contact interface geometric shapes should be selected according to different requirements. The line contact and surface contact will be affected by the terminal specification and shape, forming different macroscopic contact areas.

3. Influence of terminal positive force

Terminal positive force refers to the force generated from the contact surface between the male and the female terminals and the force perpendicular to the contact surface at the same time. With the increase of terminal positive force, the actual contact point amount and area of terminal contact interface also increase gradually, according to the analysis of action principle of contact resistance. Therefore, the actual contact area increases with the increase of positive force.

4. Influence of terminal contact interface surface state

The influence of contact interface surface state of the automotive connector terminal on contact resistance is mainly manifested in the influence of surface roughness and oxidation film condition at the contact interface on contact resistance. The roughness of contact interface has an effect on contact resistance, mainly because the difference in roughness will lead to the different amount of microscopic contact points at the contact interface and ultimately affects the size of contact resistance.

The surface oxide film at the contact interface is produced by the contact between the contact interface and the atmosphere. Chemical and electrical corrosion during use will make the situation worse. The thickness and the state of the surface oxide film determine the size of the film resistance. Therefore, the surface oxide film at the contact interface has a certain influence on the contact resistance.

In order to ensure that cars can run better, the reliability of connectors can be divided into two aspects in terms of the purpose of using, the sealing in the use of connectors as well as the spark-proof performance in running cars. In addition, connectors can also show the shielding performance and temperature control performance in the driving of cars. In the field of connector for cars sealing, the international prevailing management norm is IP67, which is now the highest level in the automobile closed industry. Although different parts of a car have different requirements of waterproof, many car manufacturers will choose IP67 to ensure the airtight performance of connector for their cars.

Power supply is a very important energy source in the running of a car, which is not only related to the normal operation of the engine, but also often involved in the use of power supply when people are driving. Therefore, there are different divisions of connector for cars in the power supply system of a car, and certain closure measures can be implemented between the male connector and the device, the male connector and the cable, the male connector and the female one as well as the female connector and the cable.

The sealing ring is a common tool to realize the sealing performance of connector for cars. This tool can not only achieve the fixed effect between different hole positions, but also achieve the sealing effect. What's more, it can guarantee the stable operation of automotive equipment and waterproof performance of the equipment in work. Made from liquid silicone and solid silicone after certain chemical changes, silicone rubber will be utilized in the production of most of the sealing ring.

As an important aspect of automobile industry, electronic circuit technology plays an important role in the stability of cars in use, which includes drivers' entertainment as well as the control system of cars when they are driving. In order to ensure that the electronic circuit technology can work stably, many shielding technologies are now applied to the production of cars. These shielding technologies play protective roles in the electronic circuit of the car and in stability of connector for cars. In addition, they can also play the role of anti-interference and anti-radiation ability in car connectors.

Connector for cars is mainly composed of the following four structural components:

1. The contacts are the core one of connector for cars to complete the electrical connection function. Generally, contact pairs are composed of positive contacts and negative contacts, and electric connection is completed through the insertion of negative and positive contacts.

Positive contacts are rigid parts in the form of cylinder (circular needle), square column (square needle) or flat shape (insert). The positive contacts are generally made of brass and phosphor bronze. The negative contacts, namely the jacks, are the critical part of contact pairs. It relies on the elastic structure to produce elastic deformation when it is inserted with the needle, and then generates elastic force to form close contact with the positive contact to complete the connection. There are many kinds of jack structures, such as the cylinder (split slot, necking), tuning fork type, cantilever beam type (longitudinal slotting), folding type (longitudinal slot, 9 shape), box (square jack) and hyperboloid spring jack.

2. The housing, also known as the shell, is the outer housing of connector for cars. It provides mechanical protection for the built-in insulating mounting plate and pin, and provides alignment of the plug and socket to attach the connector to the device.

3. Insulators, also known as the base or mounting plate of connector for cars, are used to arrange the contacts in the desired position and spacing and to ensure insulation between the contacts as well as between the contacts and the housing. Good insulation resistance, voltage resistance and good processability are the basic requirements for selecting insulating materials to be processed into insulators.

4. Accessories are divided into structural accessories and installation accessories. Structural accessories include the collar, locating key, locating pin, guide pin, connecting ring, cable clamp, seal ring, gasket. Installation accessories include the screw, nut, bolt, spring ring. Most of the accessories have standard parts and universal parts.

It is those four basic structural components that enable connector for cars to act as the bridge and operate stably.

What Capabilities Should an Automotive Connector Manufacturer Have?(2021年)

Because automobile manufacturing needs long-term authentication and inspection on the connector, connector enterprises that started late are difficult to become suppliers of joint venture factories. This also becomes one of the reasons that connector enterprises cannot develop rapidly in technology. To get ahead in technology, connector enterprises must follow the technology development of OEMs, which is unlikely to happen any time soon. Fortunately, the automotive connector enterprise has the advantage of low cost as well as high cost performance in the general and mid- and low-end products. Automotive connector manufacturers also accelerate grabbing their own brands in the OEM market.

Besides, new energy vehicles will be an important direction for the future development of the automobile industry. In addition to the traditional connector for cars, international brand manufacturers are paying attention to and constantly increasing their investment in pure electric vehicles and hybrid electric vehicles. Early research and development of automotive connector products in those fields will be a major strategy for enterprises to occupy the future market.

What capabilities should an automotive connector manufacturer have in order to keep a foothold in the industry?

1. An automotive connector manufacturer must have the similar design capabilities as a military connector manufacturer.

The technical requirements of automotive connectors are between consumer electronics and military electronics, which requires shorter use time than that of military electronics but longer than that of consumer ones and requires use environment not as harsh as that of military electronics but not as normal as that of consumer ones. Therefore, an automotive connector manufacturer must have the design capability similar to the military connector manufacturer.

2. An automotive connector manufacturer must have automated production conditions similar to those of a consumer electronics connector manufacturer.

With the consumer electronics characteristics of large market capacity, rapid replacement and great demand for production, the consumer electronic connector manufacturer enjoys outstanding supply chain management and automation degree to adapt to those characteristics of the consumer electronic connector. The automotive connectors are produced on a smaller scale than consumer electronics while more than military electronics. Automotive connector manufacturers need automation conditions similar to those for consumer electronics connectors to ensure consistency improvement of products.

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

1. Mechanical property

As far as connection function is concerned, the insertion and withdrawal force is an important mechanical property. The insertion and withdrawal force is divided into insertion force and withdrawal force (withdrawal force is also called separation force), with two different requirements. There are provisions for the maximum insertion force and the minimum separation force in the relevant standards, which indicates that, from the point view of use, the insertion force is small (Thus there are low insertion force LIF and no insertion force ZIF). However, if the separation force is too small, it will affect the reliability of contact.

Another important mechanical property is the mechanical life, actually a kind of durability index, of car connectors. Taking one insertion and one withdrawal as a cycle, it is based on whether the car connector can normally complete its connecting function (such as contact resistance value) after that specified cycle.

The insertion and withdrawal force and mechanical life of car connectors are related to the structure of contact parts, coating quality of contact parts and dimension precision of contact parts arrangement.

2. Electrical property

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

1) Contact resistance

High quality car connectors should have low and stable contact resistance. Car connectors have contact resistances ranging from a few to tens of milliohms.

2) Insulation resistance

Measures of insulation performance between contacts and between contacts and housing of car connectors range in the order of hundreds to thousands of terabytes.

3) Dielectric strength

It refers to the ability to withstand rated test voltage between contacts or between contacts and housing of car connectors.

3. Environmental property

Common environmental properties include temperature resistance, humidity resistance and salt spray resistance.

1) Temperature resistance

At present, the highest operating temperature of car connectors is 200℃ (except for a few special high temperature connectors), and the lowest temperature is -65℃.

2) Humidity resistance

Moisture intrusion can affect insulation and corrode metal parts.

3) Salt spray resistance

When the car connector works in the environment containing moisture and salt, its metal structure and contact surface treatment layer may produce electrochemical corrosion, affecting the physical and electrical properties of the car connector. In order to evaluate the ability of the car connector to withstand this environment, a salt spray test has prescribed. The car connector is suspended in a temperature-controlled test chamber and ejected with compressed air at a specified concentration of sodium chloride solution to form a salt mist atmosphere with an exposure time by the product specification of at least 48 hours.
