Technical Field
[0001] This utility model relates to the field of power equipment technology, and in particular to a grounding conductor connection device. Background Technology
[0002] In power supply facilities and equipment, grounding wires are safety devices used to temporarily short-circuit and ground de-energized equipment. Their function is to prevent harm to personnel from sudden power restoration and induced voltage from nearby high-voltage equipment during power outage maintenance or other work, while also discharging residual charge from de-energized equipment. Grounding conductors are a crucial component of power systems, ensuring the safe operation of equipment; the reliability of their connection directly affects the effectiveness of the grounding system.
[0003] Traditional grounding wire connections often use bolt crimping, which requires tools to tighten and is cumbersome. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a grounding wire connection device that is easy to install, thereby solving the problem of complicated operation of existing grounding wire connection methods.

The second vertical hole and the first vertical hole are coaxially arranged, and the second horizontal hole and the first horizontal hole are coaxially arranged.
[0007] The clamping assembly includes a copper post installed inside the first vertical hole, a spring located below the copper post, and a copper post hole on the side of the copper post. During installation, the copper post is pressed so that the copper post hole is coaxial with the first horizontal hole and the second horizontal hole. The grounding wire passes through the first horizontal hole, the second horizontal hole and the copper post hole. When the copper post is released, the copper post hole clamps the grounding wire, and the grounding wire contacts the copper busbar.

[0009] Preferably, a winding auxiliary terminal is provided above the first transverse hole.
[0010] Preferably, the inner wall of the copper pillar hole is provided with anti-slip texture, the anti-slip texture is a sawtooth structure and the depth is 0.5-1.2mm.
[0011] Preferably, the copper pillar hole and the horizontal hole of the grounding box are the same size.

[0013] Preferably, the shape of the copper pillar can also be set to rectangular or elliptical according to actual needs.
[0014] The beneficial effects of this utility model are: by setting a grounding box, setting a grounding copper busbar inside the grounding box, and setting a clamping component inside the grounding box, when the grounding wire passes through the grounding copper busbar, the clamping component clamps the grounding wire onto the grounding copper busbar.

[0018] Explanation of reference numerals in the attached drawings: Grounding box 11; First vertical hole 111; First horizontal hole 112; Mounting hole 113; Copper busbar 12; Second vertical hole 121; Second horizontal hole 122; Copper pillar 13; Copper pillar hole 131; Spring 14; Back tooth 15; Limiting plate 16; Winding auxiliary terminal 17. Detailed Implementation
[0019] Please see Figure 1-3 As shown, this application provides a technical solution: a grounding wire connection device, a grounding box 11, and a first vertical hole 111 that is not through and a first horizontal hole 112 that is perpendicular to the first vertical hole 111 inside the grounding box 11;
[0020] A grounding copper busbar 12 is installed inside the grounding box 11. A second vertical hole and a second horizontal hole are provided on the grounding copper busbar 12. The second vertical hole 121 and the first vertical hole 111 are coaxially arranged, and the second horizontal hole 122 and the first horizontal hole 112 are coaxially arranged.
[0021] The clamping assembly includes a copper post 13 installed inside the first vertical hole 111, a spring 14 located below the copper post 13, and a copper post hole 131 on the side of the copper post 13. During installation, the copper post 13 is pressed so that the copper post hole 131 is coaxial with the first horizontal hole 112 and the second horizontal hole 122. The grounding wire passes through the first horizontal hole 112, the second horizontal hole 122 and the copper post hole 131. When the copper post 13 is released, the copper post hole 131 clamps the grounding wire, and the grounding wire contacts the copper busbar 12.
[0022] The copper busbar 12 can be grounded in other ways. When installing the grounding wire, simply press the copper post 13 to align the copper post hole 131 with the first horizontal hole 112, then pass the grounding wire through the copper post hole 131, and then release the copper post 13. The copper post 13 will spring back under the action of the spring 14, and the copper post hole 131 will clamp the grounding wire. At this time, the grounding wire will contact the copper post 13 and the copper busbar 12, and the grounding wire, copper post 13 and copper busbar 12 will form a grounded electrical circuit. Compared with the installation bolt, this structure greatly saves installation time and improves the work efficiency during installation.
[0023] The first horizontal hole 112, the first vertical hole 111, the second horizontal hole 122, and the second vertical hole 121 can be increased or decreased according to actual needs.
[0024] Preferably, the outer wall of the copper column 13 is provided with inverted teeth 15, and a limiting plate 16 covering the inverted teeth 15 is provided above the grounding box 11.
[0025] The purpose of setting the inverted tooth 15 is to prevent the copper post 13 from popping out under the action of the spring 14 when no grounding wire is installed.
[0026] Preferably, a winding auxiliary terminal 17 is provided above the first transverse hole 112.
[0027] In this way, if a grounding wire extends beyond the grounding box 11 and is wound onto the winding auxiliary terminal 17, the overall reliability is increased. The winding auxiliary terminal 17 can be symmetrically arranged on both sides above the first horizontal hole 112, so that the grounding wire can be inserted into the first horizontal hole 112 from any direction and then wound onto the winding auxiliary terminal 17.
[0028] Preferably, the inner wall of the copper pillar hole 131 is provided with anti-slip texture, which is a sawtooth structure with a depth of 0.5-1.2mm.
[0029] The anti-slip texture is mainly designed to increase friction, thereby increasing the clamping force of the copper pillar hole 131.
[0030] Preferably, the copper pillar hole 131 and the horizontal hole of the grounding box 11 are the same size.
[0031] Preferably, the spring 14 is made of stainless steel, and the grounding box 11 has a mounting hole 113 at the bottom; the grounding copper busbar 12 is made of tin-plated copper alloy, and the surface is covered with an anti-corrosion coating, and the thickness of the grounding copper busbar 12 is greater than the diameter of the copper post hole 131.
[0032] Preferably, the shape of the copper pillar 13 can also be set to rectangular or elliptical according to actual needs.
[0033] During operation, pressing the copper post 13 compresses the spring 14, causing the copper post hole 131 to completely align with the first horizontal hole 112 in the middle of the grounding box 11. After passing the grounding wire through the grounding box 11 for a short distance, the copper post 13 is released, and the spring 14 rebounds, locking the grounding wire in place. The copper wire extending beyond the grounding box 11 is wound onto the winding auxiliary terminal 17 to increase reliability. The anti-slip texture inside the copper post hole 131 makes close contact with the surface of the copper wire, ensuring low-resistance conduction.
