Introduction to the basic common sense terminals

Terminal as a connector, conductivity is its primary role. Wire through the terminals and circuit boards, controllers and other connections, to ensure the normal operation of equipment. The main factors that affect the conductivity of the terminal are: the choice of conductive materials, the contact structure of the terminal design, the size of the conductive elements and the coating of conductive material surface treatment.

1. Material selection

Terminal copper as a conductive material, its conductivity is listed next to the metal in the first silver, with excellent electrical and mechanical properties, high hardness, easy to deformation; outer layer of tin, enhanced terminal corrosion resistance. The company is located in:

2. contact structure design

Terminals using internationally accepted plug-in, spring-type, track-type connection, the conductor can be in close contact with the metal conductive parts, and the contact is firm, not easy to loose.

3. processing size

The use of high-precision processing machine tools, strict quality of the good terminal products, the terminal size of the processing error reduced to the minimum allowable value, and regular inspection of manufacturing molds, maintenance, to ensure that each terminal is produced fine.

4. surface treatment process

Terminals on the metal conductive parts with tin treatment process, to ensure good contact performance, reduce the contact resistance, in addition, the tin also has good corrosion resistance; recently, also produced a gold-plated terminal, gold conductive times In copper, but gold has the stability and the best signal transmission performance, signal loss can be minimized.
