Description

Wire harness connector convenient to quick assembly disassembly

Technical Field

The utility model relates to the technical field of wire harnesses, in particular to a wire harness connector convenient to disassemble and assemble quickly.

Background

The connector is one of common fittings of the wire harness, is arranged between the wire harness and the wire harness, and has certain insulating and sealing properties, so that two or more cables can continuously run. The existing wire harness connector mostly adopts a direct plug-in and threaded pipe screwing mode.

For the wire harness connector which is directly plugged, plugging is laborious when in use. In order to reliably connect the male terminal and the female terminal of the connector, the male terminal is generally rocked left and right when the male terminal is plugged on the female terminal, and if pins of the male terminal are not aligned with pin holes on the female terminal, the pins are broken, so that the connector cannot be used. Although the structure can realize quick plugging and disassembling, the structure is vulnerable.

For the wire harness connector in the threaded pipe threaded connection mode, after the male terminal and the female terminal are required to be aligned in use, the threaded pipe on the outer side of the male terminal is screwed and sleeved on the external thread on the outer side of the female terminal. During installation, misalignment of the male and female terminals often occurs due to one hand twisting the threaded tube, resulting in the other hand being offset. At this time, the threaded pipe is screwed, so that the threaded pipe is inclined, and sliding occurs between the internal threads of the threaded pipe and the external threads of the female terminal. For a long time, the terminal connection is unstable, and the wire harness use is affected. Although the structure is favorable for prolonging the service life of the joint, the disassembly and assembly require screwing the threaded structure, dislocation blocking is easy to occur, and the operation is relatively difficult and can not be completed quickly.

Accordingly, there is a need to provide a new wire harness connector for solving the above-described technical problems.
