摘　　要：国内开关触头元件的银触点通过铆接工艺与触桥形成电气连接,银触点和触桥之间易形成较大的接触电阻,通电使用发热量大,长时间使用可靠性降低,影响开关安全和寿命。基于银触点焊接工艺,通过对触点结构和材料进行分析研究,设计了银触点焊接的开关触头元件。试验表明,触头元件的银触点固定方式采用焊接的开关性能相对铆接得以提升。The silver contact of domestic switch contact elements is electrically connected with the contact bridge through riveting process.It may cause a large contact resistance between the silver contact and the contact bridge,which generates a lot of heat when powered on,reduces the reliability for long-term use,and affects the safety and service life of the switch.Based on the welding process of silver contact,through the analysis and research of contact structure and material,the switch contact element of welding silver contact is designed.The test shows that the performance of the switch with the contact element of welding silver contact is improved compared with the switch with the contact element of riveting silver contact.
