The application of terminal plating can not only reduce corrosion on the surface of the terminal material, but also improve the insertion force state. To reduce the insertion force, you need to reduce friction. There are three main factors that affect the friction coefficient between terminals: material, surface roughness, and surface treatment. The surface roughness of different plating types is the smallest for reflowed bright tin and the largest for silver. The insertion force of terminals with different surface treatments is the highest for tin-lead, and the smallest is for gold. This is a comprehensive result of surface hardness and surface roughness. It can be seen that the insertion force performance of gold is better, and that of tin-lead is relatively poor. The pull-out force of different electroplatings has been tested and the pull-out force performance of gold is better, while that of tin-lead is relatively poor.
Insertion and extraction force test
Therefore, the plating of the terminal not only protects the surface of the terminal material from corrosion, but also improves the insertion force state. However, considering the functionality and economical cost-effectiveness, in addition to considering the insertion and extraction force design, we must also refer to the following usage conditions to select the appropriate terminal plating:
①Can withstand the actual temperature working conditions of the terminal;
②Environmentally friendly and non-corrosive;
③Has chemical stability
④ Ensure terminal contact;
⑤ Wear insulation that reduces friction;
⑥ Low cost.
As the electrical environment of the vehicle becomes more and more complex and the new energy era arrives, only by continuously exploring the manufacturing technology of components can we meet the rapid iteration of new functions.
At present, the wire harness terminals used in automotive connectors are mainly stamped from high-quality copper alloys. In order to protect the terminal base material from corrosion and optimize the surface performance of the terminal, the terminals are usually subjected to matte tin, reflow bright tin, Different surface treatments such as tin-lead, silver, gold and palladium-nickel flash gold are what we often call terminal surface plating, that is, terminal plating.
We know that terminals play two main roles in wire harness connections. One is to fasten with the plastic shell, and the other is to form an electrical connection with the mating terminal. Although copper alloy has good mechanical properties, In terms of electrical conductivity, the performance is unsatisfactory; while materials with good electrical conductivity generally have average mechanical properties, such as tin, gold, silver, etc.
