What are the requirements for the material selection of the vehicle card holder connector?
Automotive card holder connectors have strict requirements in terms of material selection, because they not only need to withstand harsh driving environments, but also need to meet safety and performance requirements. The following are several requirements for the material selection of the vehicle card holder connector:
1. Metal material requirements
1.1 Copper or nickel-based alloy: Copper or nickel-based alloy materials with good conductivity should be used for contact pins, contacts and terminals to ensure the stability and reliability of current transmission.
2. The requirements of insulating materials
2.1 High temperature flame retardancy: The insulating material should have high heat resistance and flame retardant properties to prevent the risk of fire caused by overheating.
2.2 Aging resistance: The insulating material should have excellent aging resistance and can maintain the stability of its physical and electrical properties during long-term use.
3. Plastic material requirements
3.1 Lightweight: Plastic materials should be lightweight to reduce the overall weight of the automotive card holder connector.
3.2 Weather resistance: Plastic materials should have good weather resistance and resist the erosion of natural factors such as sunlight and rain.
4. Surface treatment requirements
4.1 Uniform plating: The metal parts of the connector usually need surface treatment, such as gold plating, silver plating, etc., which requires uniform plating to ensure good conductivity and aesthetics.
5. Other requirements
5.1 Environmentally friendly and non-toxic: the material should meet the requirements of environmental protection, non-toxic and harmless, and do not contain harmful substances.
To sum up, the material selection of vehicle card holder connectors needs to comprehensively consider its conductivity, heat resistance, flame retardancy, aging resistance, lightweight, weather resistance and environmental protection. Only by choosing the right materials can the performance and safety of the vehicle card holder connector be guaranteed.
