玻璃外壳的干式磁性舌簧开关的铁合金引线与外部铜线的连接,不但要求可靠。而且不能破坏玻璃与金属间的密封的牢固性。这里介绍一种过渡铜引线连接法。它的接点电阻小,而且能耐高温。首先,把伸出舌簧开关玻璃外壳的铁合金引线的长度修剪成3.2毫米(见图)。然后,将每一根过渡铜引线的一端与位于外壁处的外部引线的一端用银焊的方法把它们焊接在一起。每一根过渡铜引线的另一端与铁合金引线用点焊连接在一起,两线呈直角。再把舌簧开关引出线的长度修剪成1.6毫米。
Glass magnetic dry magnetic reed switch ferroalloy lead and external copper connection, not only requires reliable. And can not undermine the seal between glass and metal firmness. Here is a transitional copper lead connection method. Its contact resistance is small, but also high temperature. First, the length of the ferro-alloy wire protruding out of the reed switch glass housing is trimmed to 3.2 mm (see picture). Then, one end of each of the transition copper leads and one end of the outer lead at the outer wall are welded together by silver welding. The other end of each transition copper lead is connected with the ferrous alloy lead wire by spot welding, and the two wires are at right angles. Then the length of the reed switch lead trimmed to 1.6 mm.
