A quick lock wire electrical connector

Abstract

The invention discloses a quick wire locking electrical connector which comprises a base, a torsion spring, an elastic piece, a slider, a handle, a contact terminal and a wire pressing frame. The baseis provided with a wiring hole, a spring supporting shaft and a terminal mounting hole, the slider is provided with a sliding inclined surface, a guiding groove and a positioning step, the handle isprovided with a handle top end and a spring pressing boss, the slider is provided with a slider supporting arm, the elastic piece comprises an elastic end and a wire pressing wall, the handle is hinged to the base, the elastic piece is connected to the elastic piece support shaft, the torsion spring is used for driving the elastic piece to bounce, the guiding groove is connected to a slider support arm, the slider is also connected to an elastic device for driving the slider to slide to the elastic piece, and the contact terminal passes through the terminal mounting hole. When a wire is locked, the elastic end is connected to the positioning step, the wire pressing wall presses the contact terminal, and a top end of the handle is connected to the sliding inclined surface when the wire is unlocked. After the wire locking is completed, the reliability of pressing the wire is not affected as long as the top end of the handle does not press the slider to a state in which the elastic end can slide out of the positioning step.

Description

technical field

[0001] The invention relates to the technical field of electrical connectors, in particular to a quick lock wire electrical connector. Background technique

[0002] Most of the existing on-site cable locking structures are screw locking. The advantage of screw locking is that the connection is reliable, but the disadvantage is that it takes time to install, and the current may hurt the operator through the screws, and the screws are easy to lose. In order to solve the shortcomings of screw locking wires, many companies have developed connectors with shrapnel locking wire structures, which are applied to on-site installation, avoiding the restrictions of factory installation, saving installation time, and enriching installation occasions. Most of the existing quick lock wire connectors use a crank to drive the elastic gasket to squeeze the wire and the terminal contact cable to achieve quick crimping. For example, the patent "201510149753.3" discloses "connect...
