New Energy Vehicles Connector Terminals Material Selection and Importance

With the continuous improvement of global environmental awareness, more and more people choose to purchase new energy vehicles, such as electric vehicles, hybrid vehicles and so on. In these new energy vehicles, the on-board wiring harness connector terminals are one of the very important components.

Materials Choose for Automotive Connector Terminals

In the design process of automotive connector terminals, product standards play an important guiding role. At the same time, the selection of materials also plays a key role in the performance of terminals. With the development of the new energy automotive  industry, the requirements for the performance, stability and safety of connector terminals are getting higher and higher. Therefore, when designing automotive crimp terminals, it is necessary to take into account the strong challenges faced by the connector during use. And the choice of terminal material can play a key role.

In terms of selection of terminal materials, designers need to comprehensively consider the performance of various materials in combination with product positioning, use environment, operating frequency of the connector and appearance of the connector. For parts that have conduction current and must be flexible, such as the pressing sheet of the terminal, the quality of the material is related to the electrical performance and connection performance of the terminal. Because the conductivity of the material directly affects the temperature rise and contact resistance. However, The elasticity is related to the chemical elements, elastic modulus, hardness, and tensile strength of the material. The higher the conductivity of the material, the smaller the contact resistance and the lower the temperature rise. The insertion force and the contact resistance form a quadratic relationship.

In summary, copper, silver, gold and other metal materials and alloy materials can be used to manufacture automtive stamping terminals, and the use of high-quality materials can not only ensure the stability of the terminals, but also improve the service life and safety performance of the connector.

The Importance of Automotive Connector Terminals

The terminal is a small part in the automotive electrical system, mainly used to connect various electrical equipment, including batteries, engines, lamps, sensors, controllers, etc.

In new energy vehicles, these devices are not only more diverse, but also require more precise control. So the quality and reliability of the automotive wire crimp terminals are particularly important. In the process of producing automotive wire terminals, it is necessary to adopt advanced technology and technological means to ensure the quality and reliability of the terminals. For example, the use of high-precision molding process can ensure the dimensional accuracy and surface finish of the crimp terminal pins. And the use of suitable materials, such as high-strength copper alloy, titanium alloy, etc., can improve the strength and reliability of the crimp terminals.

With the rapid development of new energy vehicles, manufacturing high-quality automotive wiring harness connector terminals is of great significance for improving the safety and reliability of automotive and achieving sustainable development.
