Detailed Description

In order to more clearly describe the technical contents of the present invention, the following further description is given in conjunction with specific embodiments.

The utility model discloses a three-plug socket protective door device for realizing L-pole and N-pole plug pin driving, which comprises a bottom plate and a lower shell, wherein the bottom plate covers the lower shell, L-pole jacks and N-pole jacks which are arranged in a triangular mode are arranged on the bottom plate, the lower shell comprises a three-plug protective door and a protective door driving surface, and in the process of inserting a plug into a socket, the plug pins are in contact with the protective door driving surface to drive the three-plug protective door to move so as to open the three-plug protective door.

In a preferred embodiment of the present invention, the lower case is further provided with a spring, and the spring is mounted on the three-way protective door and is mounted on the bottom plate under a compression force of the spring.

As a preferred embodiment of the present invention, the lower housing further comprises a protective door moving guide groove, and the triple-insertion protective door moves on the protective door moving guide groove under driving.

As a preferred embodiment of the present invention, the lower housing further includes a lower housing limiting rib, the lower housing limiting rib is disposed near the guide rail, the three-plug protective door includes a protective door height limiting surface, and in the process of inserting a single plug pin into the insertion hole, the plug pin contacts with the protective door driving panel to push the protective door height limiting surface to rotate downward and is dislocated with the lower housing limiting rib to limit the movement of the protective door.

In a preferred embodiment of the present invention, the three-pin protection door further comprises a small right-angle plane and a small plane, and the small right-angle plane and the small plane are combined to form a protection plane to prevent the insertion of the needle articles into the socket.
