Terminal material specifications:
1, insulating materials
Since 40, nylon 6.6 has been making as conductor casing and terminal block or connector accessories the best insulating material. It also is recognized by almost all international test organization. Because it has a superior ability to resist leakage current breakdown, according to the standard IEC 112 reached CTI 600, which reduces the leakage current of air and creeping distances, thereby creating smaller components.Czech Republic, and modification of electrical use nylon 6.6 do not contain halogen, fluorocarbons. It does not corrode, is off, and the allowed continuous working temperature 105 ° c guarantee temperature stability.
2, conductor material
By the Czech Republic, and production of electrical wiring terminals and connectors used in diversion is made of electrolytic copper as a standard material. The material has good conductivity and good chemical stability, Web site production in Anhui Province and the absence of compression fracture risk.
3, conductor of the contact surface
Tin alloy plating is a draft standard interface, can maintain its long-term resistance to corrosion.On the contact area of a particular thickness of tin alloy formation on the surface of gas-tight connection, so that the long-term and stable contact resistance.
4, clamping spring material
Home electric use of all clamping springs are made from high quality, carefully selected and reliable Nickel-chromium spring steel. It has high tensile strength and is proved by the many years of practical experience in ability to resist corrosion.
Relaxation phenomena in the environment changes with time under 105 ° c can be ignored, workshop decoration even in 250 ℃, 500N/m square meters under pressure, measured by value would be 1.5%.
Because the Czech Republic, and so strictly grasp the electrical connection terminals for raw materials specifications, the production of terminals and connectors accessories in creating guarantees safe and reliable connection from the machine running.
