What are the automotive connector standards? What are the component materials that automotive connectors are made of?

Automotive connectors are an important part of a vehicle's electrical system, they connect different appliances and sensors so that the entire vehicle system can run smoothly. With the continuous development of automotive electronics technology, the types and standards of automotive connectors are also increasing and improving. This article will introduce some common automotive connector standards and automotive connector components material composition. First, the automotive connector standard 1.SAE J2030: The standard applies to automotive electrical connectors and accessories. It specifies the connector design, testing, performance and labeling requirements. 2.ISO 8820: The standard applies to automotive electrical systems, safety protection device connectors. It specifies the shape, size, electrical characteristics, durability and labeling requirements of the connector. 3. USCAR-2: This standard applies to automotive electrical connectors and accessories. It specifies the requirements for connector design, testing, performance and marking, and is one of the standards for the North American automotive industry.4. DIN 72552: This standard applies to connectors for automotive electrical systems. It specifies the requirements for connector color, numbering, electrical characteristics and marking, and is one of the standards for the European automotive industry.5. JASO D 609: This standard applies to connectors and fittings for automotive electrical systems. It specifies the shape, size, electrical characteristics and marking requirements of the connector, is one of the standards of the Japanese automotive industry. Second, the automotive connector parts material composition 1. connector shell: connector shell is the main part of the connector, which is usually made of plastic materials, with good chemical resistance, abrasion resistance and temperature resistance. Connector shell material can be selected according to the requirements of the use of the environment, such as the use of the connector shell in a high-temperature environment will usually use high-temperature plastics, such as PA46, PA6T, PA9T, etc. 2. plugs and sockets: plugs and sockets are the connector is an important part of the two, which are usually made of copper, with good electrical conductivity and corrosion resistance. The structural design and size of the plug and socket should meet the requirements of the connector standard to ensure the interchangeability and reliability of the connector.3. Insulator: The insulator is usually a key component in the connector, which can protect the connector from the influence of the external environment and prevent short circuit and leakage between the electrical components. Insulators are usually made of plastic materials, such as polyamide, polyimide, etc. 4. conductive film: conductive film is another important part of the connector, it is usually coated on the surface of plugs and sockets, to increase the conductivity of the connector and corrosion resistance. Conductive film is usually made of metal materials, such as nickel, chromium, etc. 5. environmental seals: environmental seals is one of the key components of the connector, it can protect the connector from water, dust, sand and chemicals, to ensure that the connector's long-term stable operation. Environmental seals are usually made of rubber materials, such as silicone rubber, fluoroelastomer, etc. 6. external protection materials: external protection materials are mainly used for the external protection of the connector to prevent the connector from physical damage and chemical corrosion. External protective materials are usually made of polyamide, polyurethane, polyester and other materials.
