Detailed Description
The present invention will be more clearly and completely described below by way of examples and with reference to the accompanying drawings, but the present invention is not limited thereto.
As shown in fig. 1 to 3, the present invention provides an earth connection clamp, which includes a clamping groove 1, a fastening device 2 and a wiring device 3, wherein the fastening device 2 is disposed at one end of the clamping groove 1, and the wiring device 3 is disposed on the outer surface of the clamping groove 1; when the ground wire clamp is in a grounding state, the ground wire clamp is fixed in the groove of the clamp groove 1 through the fastening device 2, and current is conducted between the ground wire connected to the wiring device 3 and the ground wire clamp. The fastening device 2 is matched with the clamping groove 1, the grounding head is fixed in the groove of the clamping groove 1, the fixing performance is good, the grounding head is not directly contacted with a hand or a wiring, and the safety performance is high.
One end of the clamping groove 1 is provided with an opening, and the fastening device 2 is arranged in the opening in a penetrating way. The fastening device 2 comprises a screw 21 and a stem 22, the stem 22 being arranged on top of the screw 21. The handle 22 is used to rotate the screw 21 so that the screw 21 is screwed into the opening of the clamp groove 1. The screw 21 is made of metal, and the handle 22 is made of insulating material. The handle 22 is connected with one end of the screw 21, and the screw 21 needs to contact with a grounding head for conducting electricity, so that the handle 22 is made of an insulating material to avoid the danger caused by the conduction due to the contact of a human body.
