Description

Technical Field

[0001] The present application relates to the technical field of sockets, and in particular to a grounding socket. Background Art

[0002] The main function of the socket grounding wire is to protect personal safety and prevent electric shock accidents caused by electrical leakage. When electrical equipment leaks, the grounding wire can quickly conduct the current into the earth, making the voltage of the electrical casing close to zero, thereby avoiding human contact with the charged electrical casing and ensuring the safety of the user. In addition, the grounding wire can also reduce electromagnetic interference and protect the normal operation of electrical equipment. In household circuits, the grounding wire is an important part of protecting circuit safety and is regarded as the "lifeline."

[0003] In the prior art, the grounding wire of a socket is usually a simple copper wire extending out of the outer shell. When the electrical plug is inserted into the socket, the copper wire and the grounding terminal of the plug are freely disconnected, thereby achieving grounding protection for the electrical equipment and thus achieving a safety effect. However, the copper wire is relatively soft in texture and difficult to fix in position. It is easy to shift during use and have poor contact with the grounding terminal, causing safety hazards. Therefore, there is room for improvement. Summary of the Invention

Through this setting, the position of the electrical plug is limited, and the ground wire contact wall and the ground wire contact head are perfectly released to prevent misalignment.

[0009] It is further configured that the number of the ground wire contact arms is two and they are symmetrically arranged at both ends of the connection slot. This configuration facilitates multiple connections and improves the overall practical range.

[0010] It is further provided that the outer cover is provided with an arc-shaped flange, and the shell is provided with a rotation groove corresponding to the arc-shaped flange. The arc-shaped flange is rotated in the rotation groove with the extension direction of the arc-shaped flange as the axis.
