Significance of using contact plating for connectors

1, the connector plating anti-corrosion function: industrial electrical connectors should be the first consideration is corrosion protection. Most of the electrical connector contact shrapnel is made of copper alloy, and copper alloy in the typical electrical connector working environment is susceptible to corrosion, such as oxidation and vulcanization. 2, the connector plating helps to improve the mechanical properties: parameters related to the mechanical properties are mainly factors that affect the durability or wear of the plating, as well as mating force. These factors to be considered in the same basic effect of the two different views of the multi-point contact interface in the process of relative motion of the cold welding share. 3, connector plating helps to improve the electrical performance: the optimization of the electrical performance can be considered from the following aspects, that is, the control of the already existing and will soon be formed is located in contact with the surface film of the plating. Industrial electrical connector electrical performance of a major demand is to establish and maintain a stable connector impedance. To achieve this, a metal contact interface is required to provide such inherent stability. 4, the connector using the characteristics of precious metal coatings: to varying degrees, precious metal coatings (such as gold, palladium, and their alloys) its nature to the surface film is free. For these coatings to produce the interface of the metal contact is relatively simple, because it only needs to contact the surface of the concomitant in conjunction with the movement of the connector. 5, the connector using the characteristics of ordinary metal plating: ordinary metal plating, especially tin or tin alloy, the performance of its natural coverage of a layer of oxidized film. The role of the tin contact plating, because this layer of oxide is easy to be destroyed at the time of mating, so that the metal contact is easy to be established. The need for industrial electrical connector design is to be able to ensure that the oxide film ruptures when the connector is mated, while ensuring that the contact interface is no longer oxidized during the lifetime of the electrical connector adherence. Re-oxidizing corrosion, in the case of abrasion corrosion, is the dominant performance degradation mechanism for tin contact coatings.-6, on the BBC Electronic Products Network platform related to the introduction and sales of products brief: BBC Electronic Products Network - a professional agent / production / sales of a variety of {connectors | wiring harness | wire and cable products }; if you have a related [connectors | wiring harness | wire and cable products] purchasing / sourcing needs or would like to buy / to understand what connectors | harness | wire and cable product solutions that we can provide, please contact our Division below!
