In addition, the three-dimensional spatial dimensions of length, width and depth should be included in actual production.

[0032] Embodiment 1, refer to Figures 1 to 2 For the first embodiment of the present application, a grounding wire connecting device is provided, which comprises a wire clamp body 100 for connecting a cross arm; a crimping mechanism 200 comprising a first crimping pipe 201 arranged on the wire clamp body 100 and a connecting assembly 202 connected with the first crimping pipe 201, the first crimping pipe 201 is connected with a metal cable through the connecting assembly 202, and the first crimping pipe 201 is provided with a plurality of groups.

[0033] It should be noted that the number of first crimping pipes 201 is greater than or equal to 1, which can be set according to actual use and the size of the wire clamp body 100.

[0034] Specifically, it further comprises a fixing mechanism 300, the fixing mechanism 300 is arranged on the wire clamp body 100, and the fixing mechanism 300 is used for connecting the wire clamp body 100 with the cross arm.

[0035] Among them, the end of the second crimping pipe 202b is provided with a limiting ring 202c, the limiting ring 202c divides the second crimping pipe 202b into a plug-in part 202b-1 and a connecting part 202b-2; the length of the plug-in part 202b-1 is greater than the length of the connecting part 202b-2, the plug-in part 202b-1 is hollow, the connecting part 202b-2 is solid, the plug-in part 202b-1 is used for connecting with the metal cable, and the connecting part 202b-2 is used for connecting with the connecting column 202a, it should be noted that the connecting column can be a connecting nut, and the connecting column is mainly used for connecting the first crimping pipe and the second crimping pipe.

[0036] Further, the wire clamp body 100 is "C" shaped, a through hole is formed in the wire clamp body 100, and the pusher 301 penetrates through the through hole.

[0037] Further, the fixing mechanism 300 comprises a pusher 301 and a contact 302, the pusher 301 comprises a stud 301a and a knob 301b, the stud 301a penetrates through the through hole, and the contact 302 is used for abutting against the cross arm, when the contact 302 abuts against the cross arm, the relative position of the wire clamp body 100 and the cross arm is fixed.

[0038] Further, the first crimping pipe 201 is inserted with the connecting assembly 202, and the connecting assembly 202 is the same number as the first crimping pipe 201, and it is worth noting that the advantage of the connecting assembly 202 and the first crimping pipe 201 is that it is convenient to assemble, so that the assembly time is short, which is beneficial to save time, and when the metal cable appears "spiral" during installation, it can be solved by rotating the wire clamp body 100.

[0039] Further, the connecting assembly 202 includes a connecting column 202a and a second crimping pipe 202b, the connecting column 202a is used to connect the first crimping pipe 201 and the second crimping pipe 202b, and the second crimping pipe 202b is a deformable metal material.

[0040] Embodiment 2, refer to Figures 4 to 5 The difference between this embodiment and the first embodiment is that the first crimping pipe 201 is threadedly connected with the connecting assembly 202, and the connecting assembly 202 is the same number as the first crimping pipe 201, and it is worth noting that the advantage of the connecting assembly 202 and the first crimping pipe 201 is that when assembling, the metal cable in the first crimping pipe 201 may be rotated into a spiral shape, and in actual use, the metal cable cannot be "spiral", at this time, rotating the connecting assembly 202 can solve the "spiral" of the metal cable.

[0041] Further, the fixing mechanism 300 includes a pushing piece 301, a contact piece 302 and a supporting piece 303, the pushing piece 301 includes a threaded column 301a and a knob 301b, the threaded column 301a penetrates through the through hole, the contact piece 302 is used to abut against the cross arm, and when the contact piece 302 abuts against the cross arm, the relative position of the wire clamp body 100 and the cross arm is fixed;

[0042] It should be noted that the contact piece 302 can be a smooth abutting block, and the threaded column 301a abuts against the cross arm under the action of the force, or the contact piece 302 can be a rough abutting block, which is used to increase the friction between the abutting block and the cross arm and reduce the displacement between the abutting block and the cross arm.

[0043] The supporting piece 303 is arranged between the contact piece 302 and the wire clamp body 100, the supporting piece 303 has elasticity, the supporting piece 303 is used to push the contact piece 302 towards the cross arm, and the supporting piece 303 is used to reduce the looseness between the contact piece 302 and the cross arm, and it is worth noting that the supporting piece 303 is a spring or a spring telescopic rod with supporting force, and taking the spring as an example, one end of the spring is fixedly connected with the wire clamp body 100, the other end of the spring is fixedly connected with the end of the supporting piece 303, and the threaded column 301a penetrates through the spring;

[0044] Or the spring is arranged on both sides of the stud 301a, one end of the spring is fixedly connected with the wire clamp body 100, and the other end of the spring is fixedly connected with the end of the supporting piece 303. The supporting piece 303 in the embodiment can reduce displacement of the stud 301a and the wire clamp body 100 through its elastic property, so that the case that the gap between the contact piece 302 and the cross arm becomes large does not occur.

[0045] The remaining structures are the same as those in Embodiment 1.

[0046] Embodiment 3, with reference to Figures 4 to 5 The difference between this embodiment and the above embodiments is that the connecting assembly 202 and the first crimping pipe 201 have a third connecting mode. For example, the inner wall of one end of the connecting column 202a is provided with a convex ring, the outer wall of the first crimping pipe 201 is provided with a concave ring groove, the convex ring is clamped with the concave ring groove, the other end of the connecting column 202a can be connected with the second crimping pipe 202b through the plug-in mode, or the inner wall of the connecting column 202a is provided with a threaded groove, so that the other end of the connecting column 202a is connected with the second crimping pipe 202b through the thread.

[0047] It should be noted that when the other end of the connecting column 202a is connected with the second crimping pipe 202b through the plug-in mode, an elastic buckle can be arranged to ensure that it can be automatically locked after plugging to prevent accidental falling.

[0048] The remaining structures are the same as those in Embodiment 2.

[0049] Operation process: first, the operator inserts the metal cable into the plug-in part 202b-1 of the second crimping pipe 202b until the end of the metal cable moves to the limiting ring 202c. This step ensures the correct positioning of the metal cable, laying the foundation for the subsequent fixation. Then, through special tools or manual operation, the plug-in part 202b-1 is deformed by extrusion, so that the metal cable is firmly fixed to the inner wall of the plug-in part 202b-1. This improvement not only improves the stability of the connection, but also reduces the safety hidden danger caused by the loosening of the cable.

[0050] Next, the second crimping pipe 202b is connected with the connecting column 202a to ensure the firm connection of the metal cable with the first crimping pipe 201. Then, the connecting column 202a is connected with the first crimping pipe 201 to further ensure the stable connection of the metal cable. Through the reasonable design of the connecting assembly 202, the stable connection between the metal cable and the wire clamp body 100 is realized, and the carrying capacity of the grounding wire is enhanced.

[0051] Subsequently, the clamp body 100 is fixed on the cross arm, and the pusher 301 and the contact 302 are in contact with the cross arm, ensuring that the relative position of the clamp body 100 and the cross arm is fixed. This step realizes the quick and stable connection of the clamp body 100 and the cross arm through the interaction of the pusher 301 and the contact 302 of the fixing mechanism 300, greatly reducing the installation time and improving the reliability of the grounding wire.

[0052] Finally, by rotating the knob 301b, the stud 301a moves towards the contact 302, so that the contact 302 is firmly connected with the cross arm, and the installation of the grounding wire is completed. When disassembling, by reversing the operation of the knob 301b, the fixing of the top block and the cross arm is quickly released, realizing the quick disassembly of the grounding wire. This design not only simplifies the installation and disassembly process, but also reduces the labor intensity of the operator and improves the work efficiency.
