Trigger-type wiring terminal

Abstract

A trigger-type wiring terminal. By using an integrated spring element having two ends, clamping legs can be set to be in an open state before mounting, and then the assembly can be completed simply by a one-step mounting operation, which is convenient and time-saving, thus greatly improving the assembly efficiency and further achieving automated assembly. In addition, when the clamping legs are released and are in a clamped state, an operating member protrudes outwards to form an operating portion with a certain height, such that users can more visually confirm whether a wire is securely clamped, and can switch the clamping legs from the clamped state to the open state simply by pressing the operating portion by hand, so as to pull out the wire without using any tool, thereby avoiding the problem of bruises and injuries to hands of users caused by using tools for pressing.
