Example Embodiment
[0030] Example 1
[0031] see figure 1 , this embodiment provides a special grounding clamp for power cable terminals, including a clamping mechanism and a connection mechanism arranged on the clamping mechanism; the clamping mechanism includes two clamps 2 and a connection with the clamp Connect the fixing module; the connecting mechanism includes a wire 1 connecting the two clamping plates 2, and the clamping plates 2 are connected to the ground wire. The fixing module includes a lead screw 3 connected with the two clamping plates 2, the clamping plate 2 is provided with a through hole with an internal thread, and one end of the lead screw 3 is provided with a positive thread matching the internal thread. External thread, the other end of the lead screw 3 is provided with a reverse external thread matching the internal thread. A handle 4 is provided at the end of the lead screw 3 .

Example Embodiment
[0036] Example 2
[0037] see figure 2 , this embodiment provides a special grounding clamp for power cable terminals, which is an improvement on the basis of Embodiment 1: the fixing module includes a connecting rod 5 connected with the clamping plate 2, and the two connecting The rods 5 are cross-connected, and a connecting piece is arranged between the two connecting rods 5 . The connecting member can be a spring 6 or a bolt 7, of course, the spring 6 and the bolt 7 can also be provided at the same time. The connecting rod 5 is welded on the splint 2 . The two connecting rods 2 are cross-connected, and the connecting piece is fixed at the lower part of the cross-section, similar to scissors. Of course, it can also be designed that the ends of the two connecting rods 2 are connected together, similar to tweezers, and the connecting piece is arranged between the two connecting rods 2 . Through the elastic force of the spring 6 and the tightness of the bolt 7, the distanc...
Example Embodiment
[0038] Example 3
[0039] see image 3 , This embodiment provides a special grounding clamp for a power cable terminal, which is an improvement on the basis of Embodiment 1 or 2: a limit structure is provided on the lower part of the inner side of the clamp plate 2 . The limiting structure is a limiting block 8 , which is welded to the lower part of the clamping plate 2 . The thickness of the limiting block 8 matches the thickness of the head of the connection terminal 9 . Since the terminal block is usually fixed on the fixed part, the advantage of this design is that the clamp plate 2 can hold the terminal block 9 just through the limit block 2 without clamping the fixed part. When the terminal block is removed, it can always be grounded. Ensure the personal safety of operators.
