概述

金属复合触头产品具有以下特点:

①复合电触头焊接面为纯铁材料,并带有小凸点,以增加焊接性能,能使电触头与双金属片及不锈钢片等铁基合金焊接牢固。

②焊接部位是通过熔融金属接合,其电气稳定性优于铆接型触点而且定位性好,焊接美观,若采用铆接方法,铆接过紧造成双金属变形,铆接过松造成系统电阻增大,均将造成温控器的误差。

③与钎焊型触头相比,加热时间短,作业环境清洁,适合于微小部件接合加工,尤其适用微细机构场合使用。

对金属复合触头,可根据电器通过的电流大小,选择不同的银合金材料,适用于脉冲焊接方法与触桥联接,可制备电器接触零件及双金属触桥,广泛用于继电器、微型开关、温控器、按键、温度控制器和断路保护器中。

对金属复合触头产品的生产,现有扎机、挤压机、点焊机、自动冲压机、平片机、液压机、金相显微镜、硬度计、投影仪、工具显微镜等生产、检测设备 100台套,可根据用户的具体要求进行开发生产,已形成年产2亿粒的生产能力。

应用范围

适用于脉冲焊接方法与触桥连接,广泛用于微型开关/温控器/按键和断路保护器中。
