Insulated terminal as a connector

Insulated terminals are used as a type of connector, and electrical conductivity is their 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
 The terminal uses copper as the conductive material, and 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 anti-corrosion performance of the terminal.
2. Contact structure design
 The terminal block adopts the international common plug-in type, spring type, track type and other connection modes, and the wire can be in close contact with the metal conductive member, and the contact is firm and not easy to loose.
3. Processing size
 Electrical use of high-precision processing machine tools, 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 every terminal produced is fine.
4. Surface treatment process
 The terminal is tin-plated to the metal conductive parts to ensure good contact performance and reduce contact resistance. In addition, tin also has good corrosion resistance; recently, the electric also produces gold-plated terminal blocks, gold conductivity Next to copper, but gold has stability and optimum signal transmission performance to minimize signal loss.
