The conventional production materials and characteristics of terminals are summarized as follows: Terminals and connectors, the conductive body used in the busbar is made of electrolytic copper (H65) as a basic structural material, and the conductive network performance of copper has excellent performance inferior to silver, due to The wires connected to the terminals are all copper materials. The same material and the same expansion risk coefficient generally do not develop the problem of whether the direct connection is loose.

1. Thermosetting plastic EP

It has good geometric stability, low water absorption, and is higher than the leakage scratch index. Flame retardants are very good, the best grades of thermoplastics are stable at elevated temperatures, but have poor toughness;

2. Glass fiber reinforced nylon PA-F

Glass fiber reinforced nylon has high stiffness and stiffness and is used at higher temperatures than non-reinforced nylon. Therefore, it is also suitable for the field of overvoltage protection.

Reinforced nylon absorbs less moisture than non-reinforced nylon. Apart from the above differences, the other properties of the two materials are the same. According to UL94, the flame retardant rating of fiber-reinforced nylon is from HB to V0, where the V0 type material is dyed black in most cases;
3. Thermoplastic engineering plastics to produce polycarbonate PC

Such as high hardness, good impact toughness, good transparency, dimensional stability, good insulation performance, good thermal stability and so on.

Transparent polycarbonate is particularly suitable as a covering or marking material.

Polycarbonate is resistant to mineral acids, saturated fat carbohydrates, gasoline, lipids and oils.

Polycarbonate is less resistant to solvents, benzene=lye, acetone and ammonia. Contact with certain student chemistry lab reagents may result in the formation of effective stress cracks;

4. Thermoplastic biopolyester PBT

PBT has good geometric stability, and the material has high strength and heat resistance. It also has reliable flame retardancy and excellent electrical properties;

5. Thermoplastic nylon 6.6

The quality of the insulating housings of the joint terminals is very high, the vast majority of which are made of thermoplastic nylon 6.6, a plastic that can be economically processed by injection moulding, is environmentally friendly and is recyclable.
