[0002] The automotive connector is a component that electronic engineering technicians often come into contact with. Its function is very simple: to build a bridge of communication between blocked or isolated circuits within the circuit, so that the current can flow and the circuit can achieve the predetermined function. The forms and structures of automotive connectors are ever-changing. They are mainly composed of four basic structural components, namely: contacts, shells (depending on the type), insulators, and accessories. There are nearly a hundred types of connectors needed for general automobiles, and there are about hundreds of connectors used for a single model. As people's requirements for automobiles in terms of safety, environmental protection, comfort, and intelligence are getting higher and higher, the application of automotive electronic products is increasing, which will increase the number of automotive connector applications. However, there are still certain problems when using existing automotive connectors:

[0003] For example, a kind of automobile circuit safety connector with publication number CN211530252U has the following technical scheme: it includes a port shell and a power connection plug arranged in the port shell, the port shell is integrally injection molded on the surface of the power connection plug and forms a socket at its front end, and the tail end of the power connection plug has a power connection pin exposed from the tail of the port shell. The utility model has a novel structure, adopts an integrally injection molded port shell, has strong integrity, is not easy to debond and crack during the plug-in and pull-out process, improves the circuit connection safety performance, and at the same time, the port shell is positioned and fixed by positioning convex points and T-shaped fixing grooves to avoid the port shell shifting during the plug-in and pull-out process, which causes the solder at the power connection pin to fall off and cause poor contact. However, the existing automobile connector is still not stable enough when connected and fixed with the automobile and the external connection device, and will become loose after a long time of plug-in process, and is difficult to unplug, and is easy to cause damage if too much force is used.
