1The rivet contact has two forms: a nail head layer and a double layer at both ends. The layer material can be selected from silver, gold, palladium, platinum and alloy materials. The matrix is ​​generally pure copper with good plasticity and conductivity, and precious metal material. It is only compounded at the necessary position for electrical contact of the contacts, thus effectively saving precious metals, reducing the cost of the contacts, and achieving sustainable development of society.
2 The working layer material is more flexible than the overall precious metal rivet material selection. Because the precious metal alloy material has excellent electrical contact performance, it is not suitable for making the overall rivet contact due to the poor riveting process, and the rivet contact can be used to lengthen and avoid short.
3 rivet contacts are suitable for continuous automatic production of riveting processing. No other processing techniques (such as electroplating, welding, etc.) are required after riveting, which not only simplifies the manufacturing process of contact parts, but also improves production efficiency and reduces costs. Improve assembly accuracy and reliability of components.
