The terminal is used as a type of connector, and electrical conductivity is its primary function. The wire is connected to the circuit board, controller, etc. through the terminal block to ensure the normal operation of the device. The main factors affecting the electrical conductivity of the terminal are: the choice of conductive materials, the design of the terminal contact structure, the size of the conductive components, and the treatment of the surface coating of the conductive material.
1. Material selection
Lianjie terminal block uses copper as the conductive material, its conductivity is second only to the silver listed in the first place of the metal. It has superior electrical and mechanical properties, high hardness and is not easy to be deformed; tin plating on the outer layer enhances the corrosion resistance of the terminal. performance.
2. Contact structure design
The Lianjie terminal block adopts the international common plug-in type, spring type, track type and other connection methods. The wire can be in close contact with the metal conductive parts, and the contact is firm and not easy to loose.
3. Processing size
Lianjie Electric uses high-precision processing machine tools to strictly control the quality of the terminal products, reduce the processing tolerance of the terminal to the minimum allowable value, and regularly inspect and maintain the manufacturing mold to ensure that each terminal produced is guaranteed. Boutique.
4. Surface treatment process
The contact terminals of the Jiejie terminal are tin-plated for metal conductive parts, which can ensure good contact performance and reduce contact resistance. In addition, tin also has good corrosion resistance; recently, Lianjie Electric has also produced gold-plated terminal blocks. Gold is second to copper in conductivity, but gold has stability and optimum signal transfer performance to minimize signal loss.
