What are the application characteristics and development trends of automotive connectors?
Automotive connectors are a component that electrical engineering technicians often contact. Its function is very simple: between the blocked or isolated circuits in the circuit, build a communication bridge, so that the current flows, so that the circuit to achieve the intended function. The form and structure of automotive connectors are ever-changing. They are mainly composed of four basic structural components, namely: contacts, housings (depending on the variety), insulators, and accessories. In the industry, it is also commonly called sheath, connector, and plastic case.
There are nearly a hundred types of connectors used in general automobiles, and hundreds of connectors are used in a single vehicle. As people have higher and higher requirements for automobiles in terms of safety, environmental protection, comfort, and intelligence, the application of automotive electronics is increasing, which will increase the number of automotive connector applications.
Contacts It is the core part of the automotive connector to complete the electrical connection function. The contact pair is generally composed of a positive contact and a negative contact, and the electrical connection is completed by the mating of the female and male contacts. The male contact is a rigid part whose shape is cylindrical (round pin), square cylinder (square pin) or flat (pin). The male contact is generally made of brass or phosphor bronze. The female contact is the key part of the contact pair. It relies on the elastic structure to elastically deform when mating with the pin to generate elastic force to form close contact with the male contact to complete the connection. There are many types of jacks, including cylindrical (slotted, narrowed), tuning fork, cantilevered (longitudinal slotted), folded (longitudinal slotted, 9-shaped), box-shaped (square socket), and Hyperboloid wire spring jack, etc.
The shell, also known as the shell, is the outer cover of the automotive connector. It provides mechanical protection for the built-in insulation mounting plate and pins, and provides alignment when the plug and socket are mated, thereby securing the connector to the device. . Insulators are often referred to as automobile connector bases or inserts. Its role is to arrange the contacts at the required position and spacing, and to ensure that the contacts are between the contacts and between the contacts and the housing. Insulation performance. Good insulation resistance, voltage resistance performance and easy processability are the basic requirements for selecting insulating materials forprocessing into insulators.
The accessories are divided into structural accessories and installation accessories. Structural accessories such as collars, positioning keys, positioning pins, guide pins, coupling rings, cable clamps, seals, gaskets, etc. Installation accessories such as screws, nuts, screws, spring coils, etc. Most of the accessories have standard parts and universal parts. It is these four basic structural components that enable the automotive connector to act as a bridge for stable operation.
From the purpose of the use of automobile connectors, in order to ensure better driving of the car, we can divide the reliability of the connector into the tightness of the connector in use, the performance of the car in fire prevention during driving, and the During driving, the connector can also show shielding performance and temperature control performance. Generally speaking, when discussing the tightness of a car connector, the car is not only sealed against water. In this field, the current popular international management specification is IP67, and this specification is now the highest level in the automotive industry. Although the requirements for waterproofing are different in different parts of the car, many car manufacturers will choose IP67 to ensure the tightness of the connector of their car.
In the driving of a car, the power source is a very important energy source, which is not only related to the normal work of the engine, but also often involves the use of the power source when people are driving. So in the car's power supply system, car connectors have different divisions, between the male connector and the device, between the male connector and the cable, between the male and female connector, and the female connector. There are certain sealing measures between the end connector and the cable that can be implemented.
In realizing the sealing performance of automotive connectors, the seal ring is a commonly used tool. This tool can not only achieve the effect of fixing between different hole positions, but also the effect of sealing. It can not only ensure the stable operation of automotive equipment, but also ensure the waterproof performance of automotive equipment in work. In the production of seal rings, silicon rubber is mostly used. This material is made by liquid silicon and solid silicon after certain chemical changes.
Now that automobiles are in use, electronic circuit technology is an important aspect of the automotive industry, not only in driver entertainment, but also in the driver ’s control system while driving. Electronic circuit technology has played an important role in the stable work of automobiles. In order to ensure that the electronic circuit technology can work stably, many shielding technologies are now applied in the production of automobiles. These shielding technologies not only play a protective role in the electronic circuit of the car, but also have the ability to resist interference and radiation in the parts of the car. In addition, they can also protect the stable operation of the car connector. These shielding technologies can be divided into two types: internal shielding and external shielding.
When using an external shield to protect a car connector, two identical shield shells are usually assembled to form a shield layer, and the length of the shield layer can cover the entire connector length. It is also necessary to ensure that the shield shell Sufficient locking plate structure to ensure reliable installation of the shielding layer. In addition, the shielding material used must not only be subjected to electroplating treatment, but also must be treated to prevent chemical corrosion.
