What is automotive terminal connector? What are its main specification materials?

Automotive terminal connector is a kind of connector which is widely used in automotive electrical system. Its function is to connect different electrical components together for electrical transmission. In the process of automobile manufacturing, a large number of electrical connectors are needed to connect, including sensors, lamps, batteries, motors and so on. Therefore, the importance of automotive terminal connectors is self-evident. The main specifications of automotive terminal connectors include the shape, size, number of terminals, plug form and so on. Common automotive terminal connectors are rectangular, round, oval, triangular and so on, ranging in size from several millimeters to tens of millimeters, and the number of terminals also has a variety of choices, ranging from several to hundreds. In addition, the automotive terminal connector has different plug forms, such as a one-way plug, a two-way plug, a threaded plug and the like. The selection of these specifications and characteristics is usually based on different application scenarios and electrical requirements. In terms of materials for automotive terminal connectors, common materials include: 1. Polyamide (PA): Polyamide is a high-strength, high-temperature plastic material, usually used in the housing part of automotive terminal connectors. Its advantages are high resistance to wear, impact, corrosion and insulation, and long service life in high temp and humidity environment. 2. Copper: Copper is an excellent conductive material, which is usually used in the conductor part of automotive terminal connectors. It has the advantages of good conductivity, corrosion resistance, oxidation resistance and high temperature resistance, and can ensure the reliability of electrical connection. 3. Steel: Steel is a high-strength, corrosion-resistant metal material commonly used in the spring portion of automotive terminal connectors. It has the advantages of high strength, long service life and fatigue resistance, and can ensure the stability of the connector. 4. Aluminum: Aluminum is a kind of metal material with light weight and good conductivity, which is usually used in the shell part of automotive terminal connectors. Its advantages are light weight, good conductivity, corrosion resistance and low cost, which can reduce the weight of automobiles and improve the economy. When selecting automotive terminal connectors, it is necessary to select them according to different application scenarios and electrical requirements. For example, in high temperature and humid environment, the connector using PA material should be selected to ensure the stability of the connector.
