[0002] Repeated grounding plays a vital role in the safety of temporary power supply at construction sites. It can reduce the voltage of leakage equipment to the ground. In the temporary power supply system at construction sites, repeated grounding can significantly reduce the voltage of the leakage equipment shell to the ground. If the equipment shell touches the shell in single phase, the voltage of the leakage equipment shell to the ground will be effectively reduced in the case of repeated grounding, thus providing safer protection for people.

[0003] In the prior art, the PE line and the terminal board are mostly connected by bolt anchoring, that is, the PE line is connected to the reserved hole of the terminal board by bolts. A screwdriver is needed to operate during the installation process. The construction site has a wide working area and the workload of temporary power layout is large. The above connection method is relatively cumbersome, which makes the installation and removal time-consuming and labor-intensive. Summary of the invention

[0008] Preferably, a through hole is provided at the rotating portion, and a torsion spring is provided in the through hole, and the torsion spring is used to provide an elastic force to keep the clamping parts of the two clips clamped toward each other.

[0009] Through the above structure, the upper clamping piece and the lower clamping piece are clamped toward each other, thereby achieving a quick and stable connection and improving the contact quality with the terminal board.

[0010] Preferably, the anti-slip component includes an anti-slip pin and a nut. The anti-slip pin has a plug-in portion for cooperating with a reserved hole at the terminal board and a threaded portion for cooperating with a circular hole. The nut is arranged on the side of the clamping portion away from the rotating portion and is used to cooperate with the threaded portion to limit the anti-slip pin.

[0011] Through the above structure, the user only needs to insert the anti-dropping pin into the reserved hole and pass it through the round hole, and then rotate the nut to complete the installation, which reduces the installation steps and can be completed without tools, thereby improving work efficiency. At the same time, the user can also change the size of the anti-dropping pin according to the size of the reserved hole of the terminal board or the thickness of the terminal board.

[0013] Through the above structure, the anti-dropping piece will not interfere with the lower clamping piece when the lower clamping piece rotates along the rotating part.

[0014] Preferably, the diameter of the threaded portion is smaller than the diameter of the plug-in portion.

[0015] Through the above structure, the anti-dropping pin can be fixed at the circular hole of the upper clamping piece, so that it can be inserted into the reserved hole of the terminal board, thereby increasing the contact area between the connector body and the terminal board.

[0019] The above structure can more effectively resist vibration, impact or twisting force from all directions, thereby maintaining the stability of the connection, while facilitating production and reducing the manufacturing difficulty and cost that may be caused by asymmetric design.
