Wire plugging device

Abstract

The invention relates to a wire plugging device. The wire plugging device comprises an insulating shell, a conductor and an elastic locking assembly, wherein the elastic locking assembly and the conductor are located in the insulating shell, the conductor is connected with the elastic locking assembly, the elastic locking assembly is provided with a locking piece, an operating piece and an elastic piece, the operating piece and the locking piece are oppositely attached within a certain length range, the operating piece can do linear reciprocating sliding motion relative to the locking piece, the elastic piece is limited in a cavity jointly enclosed by the operating piece and the locking piece through the operating piece and the locking piece, and the operating piece applies force to the elastic piece through pressing operation to enable the elastic piece to deform so as to drive the free end of the elastic piece to be close to or far away from the locking piece, thereby pressing or loosening a cable. According to the invention, stable limiting of the elastic piece is guaranteed, and the problem that connection between a cable and an electric conductor is not stable is well solved; and the operating piece can be prevented from deviating, the elastic piece can be accurately and effectively compressed or restored, the cable can be accurately assembled and disassembled, assembling is simple, and production procedures are reduced.

Description

technical field [0001] The invention relates to the technical field of electrical connection, in particular to a wire insertion device. Background technique [0002] In the prior art, shrapnel crimping type terminals are widely used. The traditional shrapnel crimping type terminal includes a shrapnel and a metal conductor. One end of the shrapnel is fixedly connected to the metal conductor, and the other end of the shrapnel is in contact with the metal conductor. When wiring, pass The auxiliary tool presses the button to compress the end of the shrapnel that is in contact with the metal conductor, opens the gap between the shrapnel and the metal conductor, and connects the cable; when removing, press the button with the auxiliary tool to compress the end of the shrapnel that is in contact with the metal conductor. At one end of the shrapnel, take out the cable, and then the shrapnel rebounds back to the original state. However, the traditional shrapnel crimping terminal has...

AI Technical Summary

Problems solved by technology

However, the traditional shrapnel crimping terminal has the following problems in specific applications: First, the shrapnel is clamped in the metal conductor, and the surrounding of the metal conductor limits the shrapnel, and it is easy to cause the shrapnel to break out during the process of frequently compressing or restoring the shrapnel through auxiliary tools. Offset, the cable cannot be effectively connected to the metal conductor, resulting in an unstable connection between the cable and the metal conductor; the second is to press the button through an auxiliary tool, the button is prone to offset during the sliding movement, and cannot accurately and effectively compress or return the shrapnel, the shrapnel The gap between the metal conductor and the metal conductor cannot be opened or retracted quickly and accurately, which makes it very inconvenient to insert or remove the cable; third, the metal conductor has a complex structure and complex molding, and it is also difficult to put the metal conductor into the shell.
