闭锁式接电开关在应用中有时会出现不能闭合的现象,为了提高其工作可靠性,对开关零部件中惯性销和内接电片的结构进行了改进,采取了增加惯性销质量、在惯性销的底部两侧开透气槽、改善惯性销头部圆锥角度、减小内接电片支耳宽度等措施,经过仿真与试验,验证了上述改进措施的有效性,改善了内接电片受力状态,有利于使其产生有效变形,提高了闭锁式接电开关的工作可靠性。

Closed-access electrical switch may not be closed in practical application sometimes, so in order to enhance its reliability, the structure of the inertial pin and internal electrical sheet should be improved. This can be done by increasing the mass of the inertial pin, making ventilating groove on both sides of the bottom of inertial pin, changing the inertia cone angle of the head pin, decreasing the width of the support lug of the electrical sheet, so on and so forth. Through simulation and experiment, the above-mentioned measures were verified to improve the force access on the internal electrical sheet and make it deform effectively, and improve the reliability of the closed-access electrical switch.
