[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A safe and stable socket connector comprises a shell, a plug-in body and a metal connector, the shell is provided with a mounting slot, the plug-in body is connected to the mounting slot, one end of the shell is rotatably connected to a protective cover assembly, the protective cover assembly is detachably connected to the shell, the other end of the shell is connected to a power cord, one end of the plug-in body is provided with a slot, the other end of the plug-in body is connected to a limiting bracket, the limiting bracket is provided with a connecting hole, the connecting hole is connected to the slot, one end of the metal connector is placed in the slot, the other end of the metal connector extends out of the connecting hole and is connected to a winding limit block, the metal connector is snap-fitted to the connecting hole, and there is a distance between the winding limit block and the limiting bracket.

[0008] The interior of the shell is a cavity structure and is provided with a mounting groove, so that the plug-in body fixed in the mounting groove is protected by the shell, and the plug-in body is used to position and fix each metal connector, one end of the metal connector is provided with a front end and is placed in the front end slot of the plug-in body for external plug, and the other end extends from the rear end of the plug-in body for winding the power line, and the wire is a conductive wire connected inside the power line, and the end of the conductive wire is wound around the metal connector to energize the metal connector, wherein the middle and rear part of the metal connector is clamped at the connection hole for fixing, and the rear end head of the metal connector is connected to the winding limit block, so that the end structure of the metal connector protrudes to limit the position of the wound wire to prevent it from slipping out, and at the same time the winding limit block and the metal connector are There is a gap between the clamped limit brackets, which makes wire winding more convenient and stable, thereby improving the conductive stability and safety when the socket is in use. The winding limit block and the metal connector are an integrated structure to ensure that the wire has sufficient contact surface to ensure conductivity; the front end of the shell is connected to the protective cover assembly, so that the plug-in body in the installation slot is protected by the protective cover assembly. When the socket is not in use, the inside of the protective shell is protected from foreign matter such as dust and liquid. At the same time, the metal connector is isolated from contact with the outside world to prevent electric shock hazards caused by accidental touch. The protective cover assembly is detachable, which is convenient for assembly and can be disassembled for use and later maintenance, so as to improve the applicability of scenarios and extend the protection period and the service life of the socket. The effect of improving the stability of the connection between the internal structures of the socket, enhancing the safety of the socket, improving practicality and extending the service life is achieved.

[0009] Preferably, the protective cover assembly includes a rotating bracket and a cover shell. The rotating bracket is connected to the outer shell. One end of the cover shell is provided with a movable groove. The rotating bracket is plugged into the movable groove. The groove wall of the movable groove and the rotating bracket are both provided with a rotation hole. A rotating rod is plugged into the rotation hole. The cover shell is provided with a placement groove. The outer shell is snapped into the placement groove. The protective cover assembly includes a rotating bracket connected to the upper end surface of the outer shell. The cover shell is snapped into the rotating bracket through the movable groove, so that the rotation hole of the rotating bracket and the rotation hole of the movable groove are arranged relative to and connected. Then, the cover shell can be rotated based on the rotation rod as a fulcrum by inserting the rotating rod into the rotation hole. The placement groove is a concave structure on the inner side of the cover shell. By rotating, the front end of the outer shell enters the placement groove of the cover shell for protection. This improves the connection stability and operation stability of the cover shell and enhances the protection stability of the socket.

[0015] Preferably, the second limiting bracket has a mounting hole that communicates with the second sunken groove. A locking catch is connected to the mounting hole, and the pin is provided with a limiting groove, which engages with the locking catch. The second limiting bracket has a mounting hole that communicates with the second sunken groove. When the pin is inserted into the second mounting hole, it slides against the locking catch and pushes against it. The locking catch exerts a certain degree of deformation until the block enters the second sunken groove, at which point the locking catch engages the limiting groove, making the connection quick and convenient. It also prevents the pin from being pulled out of the second connection hole by the wire connection, thereby securing the pin from both the front and back. This improves the installation stability of the clip pin and ensures electrical safety.
