Description

Technical Field

[0001] This utility model relates to the field of automotive connector technology, specifically to an easily detachable automotive connector housing. Background Technology

[0002] Automotive connectors, also known as automotive plugs, are core electronic components in automotive circuits that enable current / signal transmission and connection. Essentially, they use a detachable plug and socket structure to allow stable circuit conduction for various automotive electrical systems (such as the engine, headlights, and central control).

[0003] Automotive connectors consist of contacts, insulators, and housings. To ensure precise mating of plugs and sockets and to prevent automotive connectors from detaching while the vehicle is in motion, latches and locating pins are installed on the surface of the automotive connector housing.

[0004] A search revealed, for example, a Chinese patent application with publication number CN209544716U, which discloses an aluminum automotive air conditioning connection device. This connection device uses a double locking structure of a locking pin and a spring to ensure the firmness of the connection between the female connector housing and the male connector housing. At the same time, a simple sealing ring structure fills the gap between the female connector housing and the male connector housing, improving the waterproof effect and preventing condensation from seeping in. In addition, a sliding groove pre-positions the pin before it contacts the female connector, preventing the pin from being damaged.

[0005] However, in actual use, the double locking of the pin and spring relies on the "endurance deformation capability of the elastic element". However, the continuous vibration of the car air conditioner causes the spring to "metal fatigue, which gradually reduces the elasticity. This may result in a decrease in locking force or even breakage of the spring, which in turn leads to loosening of the male and female shell connection.

[0006] Furthermore, when the connector needs to be disassembled for maintenance, forced disassembly may damage the locking pin or spring, rendering the connection unusable and increasing maintenance costs. Utility Model Content

[0007] The purpose of this utility model is to provide an easy-to-disassemble automotive connector housing. The limiting block and the fixing post slide inside the slide groove and the circular groove respectively, limiting the plug during the process of the plug being inserted into the socket. The locking block is fixed to the plug by the cotter pin, locking the plug. At the same time, it is also convenient to disassemble the socket and the plug.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an easily detachable automotive connector housing, including a socket, wherein the socket includes a socket housing, and one end of the socket housing is provided with an extension plate;
