Description

Technical Field

[0001] This utility model relates to the field of wire harness connector technology, specifically a high-stability wire harness connector. Background Technology

[0002] Wire harness connectors are a type of terminal. Connectors, also known as plugs, consist of a plug and a socket. Connectors are relay stations in automotive circuits for wire harnesses. Wire harness connector products are used in automobiles, home appliances, instruments, office equipment, commercial machines, electronic component leads, and electronic control boards, and are applied in digital products, home appliances, and the automotive industry.

[0003] Chinese Patent CN220670889U discloses a pneumatic connector device for connecting a scanning valve and a pressure measurement model in an automotive wind tunnel. The device includes a male connector and a female connector. Several first pressure measurement channels are axially inserted within the male connector. The outer wall of the end of the male connector used to connect to the female connector has external threads, and the inner wall has multiple fixing sliders. The female connector has a T-shaped cylinder and a threaded sleeve fitted onto the T-shaped cylinder. The T-shaped cylinder has several through holes axially adapted to the first pressure measurement channels. The side of the smaller diameter end of the T-shaped cylinder has a guide groove for positioning the fixing sliders. The male connector slides into the guide groove via the fixing sliders, allowing the first pressure measurement channels to be inserted into the through holes of the female connector cylinder. Then, the threaded sleeve is rotated to achieve a threaded connection between the external threads and the threaded sleeve. Compared with existing technologies, this invention utilizes the fixing sliders on the male connector and the guide grooves on the female connector for positioning, quickly and conveniently connecting the pressure measurement plug to the through holes one by one.

[0004] However, the above technical solution has the following defects: In the above connector structure, the threaded sleeve is connected to the external thread on the male connector. When the connector is in use, the shaking or vibration will cause the threaded sleeve to rotate to a certain extent. Over time, the threaded sleeve will easily loosen, affecting the stability between the two connectors. Utility Model Content
