So which are the choice of copper wire and cable as electricity, cable, extensive use of information transmission, but also in electronic connectors inside the profession for the best buy in spite of good electrical conductivity of pure copper material direct connector 2510 (2-20) , but its mechanical strength and heat resistance connector, the connector is not sufficient to reach the professional standard, so increasing demand some alloying elements never advances its mechanical strength and heat resistance, although good electrical conductivity of pure copper, but its mechanical strength and heat resistance, an inadequate response to the demand for electrical connectors, it is necessary to increase the progress of alloying elements to the mechanical strength and heat resistance, but due to increased metal atom itself having a specific scale, when added to pure copper connector XHB (2-20 ), resulting in the difference between the atoms return to distort the copper atoms placed, resulting in the transmission process and then weakened or blocked. Common market are: brass (Cu-Zn); brass (Cu-Sn); Yang white alloy (CU-Ni); but its mechanical strength and heat resistance than pure copper is good. Connector anti corrosion coating function connector should first consider is corrosion protection. Most electrical connector contact shrapnel is made of copper alloy, and a copper alloy in a typical electrical connector working environment susceptible to corrosion, such as oxide and sulfide. In fact, the contact coating is used to close the contact with the working environment shrapnel spaced to prevent corrosion of copper. Of course, the coating material must not be damaged (at least in the hazardous range) in its working environment. As an important feature of the corrosion protection while optimizing the contact interface to select an appropriate coating material considerations.
