Material

1. Conductive material:

? Copper: It has good conductivity and ductility, and is a commonly used material for making terminal blocks.

? Brass: It is relatively inexpensive and has good conductivity, but may lose elasticity after repeated compression.

? Phosphor bronze: With good conductivity and mechanical properties, affordable price, commonly used in ordinary connectors.

? Silver: Low resistivity, excellent conductivity, but expensive and prone to oxidation in sulfur-containing environments.

? Gold: It is an excellent conductive material with strong corrosion resistance, but it is also expensive and generally used in special electronic systems.

2. Insulation material:

? Nylon (PA): such as nylon 66, which has high strength, high rigidity, and good wear resistance, is commonly used to make the housing and insulation components of connectors.

? Polybutylene terephthalate (PBT): Low cost, high strength, friction resistance, but poor formability, commonly used in the production of specific types of connectors.

? Liquid crystal polymer (LCP): It has excellent heat resistance, low coefficient of linear expansion, and low injection molding shrinkage, making it suitable for producing high-precision and high reliability connectors.

? Polyvinyl chloride (PVC): It has good insulation properties and weather resistance, and is commonly used to make wire insulation layers.

3. Other auxiliary materials:

? Coating materials: such as tin, nickel, gold, etc., used to improve the conductivity, corrosion resistance, and aesthetics of connectors.

? Sealing materials: such as rubber gaskets or silicone sealing plugs, used to improve the waterproof performance of connectors.

Tool

1. Stamping equipment: used to stamp conductive materials into the desired terminal shape.

2. Injection molding equipment: used to inject insulation materials into the housing and insulation components of connectors.

3. Electroplating equipment: used to coat the required coating material on the terminals.

4. Testing tools: such as multimeters, bridges, etc., used to test the electrical performance of connectors.

5. Assembly tools: such as screwdrivers, wrenches, etc., used to assemble connectors and terminals onto automotive wiring harnesses.

6. Automated production line: including automatic feeding, stamping, injection molding, electroplating, testing, and assembly, which can significantly improve production efficiency and product quality.

In summary, customizing automotive terminal blocks requires a range of professional materials and tools, and the selection and use of these materials and tools will directly affect the performance and quality of the connector. Therefore, in the customization process, it is necessary to strictly follow relevant standards and specifications to ensure the reliability and safety of the product.
