Analysis of influencing factors on electrical conductivity of terminal

As a kind of connector, terminal conductivity is its primary function. The conductor is connected with the circuit board and the controller through the terminal to ensure the normal operation of the equipment. The main factors that affect the conductive performance of terminal are: The selection of conductive material, the design of terminal contact structure, the size of conductive element and the treatment of conductive material surface coating.
　　1. Material Selection
　Copper as a conductive material, its electrical conductivity is next to the first in the metal silver, with superior electrical and mechanical properties, high hardness, not prone to deformation;.
　　 2. Contact Design
　　Adopting the international common connection mode of plug-pull type, spring type, track type, etc. , the conductor can be in close contact with the metal conductive parts, and the contact is firm and not easy to loose.
　　3. machining dimensions
　　The use of high-precision machining machine tools, strictly control the quality of good terminal products, wiring terminal processing size error to the minimum allowed value, and the manufacture of regular inspection and maintenance of the mold, ensure that the production of each terminal is a boutique.
4. Surface treatment process
　　In addition, tin has a good anticorrosion property. Recently, Jinghong Electric has also produced gold-plated terminal terminals, gold is inferior to copper in conductivity, but the gold has the stability and the best signal transmission performance, may reduce the signal loss to the minimum.
