Description

抗突波的绕线电阻及其制法
技术领域 本发明涉及一种抗突波的绕线电阻及其制法，尤指一种两端帽盖电焊处被电镀一层 金属电镀层， 以大幅提高焊点的可靠度。
背景技术
传统绕线电阻的结构如图 1及图 2所示， 在图 2中， 绕线电阻 10具有一陶磁棒 11， 陶 磁棒 11的左右两端各接位于右端的第一铁帽 121及位于左端的第二铁帽 122， 一金属绕线 13沿着陶磁棒 11的周围自第一铁帽 121上的线头 131之处向着第二铁帽 122上的线尾 132 之处螺旋缠绕着陶磁棒 11， 之后， 用一电焊机将该金属绕线 13的线头 131焊接固定在该 第一铁帽 121上的线头电焊处 1311， 且将该金属绕线 13的线尾 132焊接固定在该第二铁帽 122上的线尾电焊处 1321， 接着， 在该第一铁帽 121及该第二铁帽 122之右左延伸出一第 一引线 141及一第二引线 142， 而形成一传统的绕线电阻。 传
统的抗突波电阻的主流产品不是绕线电阻， 因为， 此种传统的绕线电阻于突波瞬间 能量在 100瓦以上时， 该突波会造成一定比例的电焊处的绕线松动， 而影响抗突波特性， 也就是说传统上所制造的绕线电阻因为将线头或线尾电焊 (welding)至铁帽上时， 电焊的 太深、 太浅或偏歪 (如图 1， 可见陶磁棒 91上的第二铁帽 922上电焊处 9321的位置， 绕线 93的线尾 932电焊歪了)， 由于焊接处焊的不好 (例如电焊机械)导致焊点与铁帽间的接触 电阻升高， 因此， 突波会造成焊点松动， 因而导致某一比例的绕线电阻焊点失败率， 传 统上绕线电阻的耐突波焊点失败率约 10 ppm。 由于上述耐突波焊点失败率仍太高， 故绕 线电阻产业上急需要一种耐突波焊点可靠度高的抗突波绕线电阻。
针对上述现有技术的缺陷， 本发明提供一种高可靠度的绕线电阻， 以降低耐突波焊 点失败率并提高抗突波的可靠度。
