Technical requirements for automotive connectors 

 Conductivity, contact performance, durability, electromagnetic compatibility, thermal stress relaxation, stress resistance relaxation 

 The technical requirements of automotive connectors mainly include the following aspects: 

 Conductivity and contact performance: Automotive connectors need to have good conductivity and reliable contact performance to ensure the stable transmission of current. This requires high-quality materials and sophisticated processes in the design and manufacture of connectors to ensure the stability and durability of contact parts.1 

 Durability: Automotive connectors need to have high durability and maintain stable performance during long-term use. This includes high-precision manufacturing processes, such as accurate mold design, high-quality material selection and strict production control processes to ensure the stability and reliability of connectors.1 

 Electromagnetic compatibility (EMC): With the development of automotive electronic and intelligence, connectors need to have good electromagnetic compatibility to avoid electromagnetic interference and ensure the normal operation of vehicle electronic systems 1. 

 Thermal stress relaxation and stress relaxation resistance: High-voltage connectors need to have good thermal stress relaxation and stress relaxation performance in high temperature environments to maintain their current carrying capacity and stability 1. 

 High-voltage protection design: High-voltage connectors need to be specially designed to deal with safety problems and temperature rise in high-voltage environments to ensure that they can still work normally at high temperatures 1. 

 Design simulation test ability: The design of the connector needs to be strictly simulated to ensure its performance under various working conditions, including temperature, vibration, humidity and other environmental factors 1. 

 High vibration requirements: Automotive connectors need to be able to work steadily in a high vibration environment, which requires the connector design to consider the impact of vibration on performance and carry out corresponding optimization design 1. 

 Environmental protection and sustainability requirements: With the increase of global environmental awareness, automotive connectors need to meet environmental protection and sustainability requirements in the manufacturing and use process, reduce the use of harmful substances, improve the recyclability of products, and reduce energy consumption 1. 

 Mechanical performance: The mechanical properties of the connector include the bending strength, plugging force, insertion force, retention force, etc. of the terminal itself. The testing and optimization of these properties are the key to ensuring that the connector works stably under various working conditions 2. 

 Sealing level and protection level: The sealing level and protection level of the connector need to meet specific environmental requirements, such as waterproofing and dustproof, to ensure its reliability in harsh environments 2. 

 Together, these technical requirements ensure that car connectors can work steadily and reliably in a complex and changeable automotive environment.
