As an important component of wall switch sockets,the performance of terminals directly affects the wiring stability and safety of switch sockets.The most important performance of terminals is the stability of wire clamping,and it is also necessary to consider various wiring scenarios of actual users,otherwise there may be wire detachment,and even safety accidents such as high temperature rise and burning due to loose wire clamping.Therefore,studying the terminal clamp structure of wall switch sockets is of great significance.This article first analyzes the wire clamping limit structure of terminals,and then conducts practical verification research on various wire clamping limit structures.
