Description

Technical Field

[0001] This utility model relates to the field of grounding pile technology, and in particular to a wire grounding device. Background Technology

[0002] A grounding wire is a wire that directly connects to the earth; it can also be called a safety return line. In dangerous situations, it transfers high voltage directly to the earth, essentially acting as a lifeline. To ensure a better connection with the earth, the resistance of the grounding wire should be as low as possible. Therefore, electrical accessories are usually equipped with fixed grounding stakes. These grounding stakes need to be used in conjunction with the grounding terminal clamps of the grounding wire to achieve a good grounding effect.

[0003] However, in actual work, there are too many electrical devices in the power supply site (such as substation). Since one grounding wire can only be connected to one grounding post, there are many grounding posts in the power supply site, and the grounding wire connection is complicated. This not only affects the subsequent maintenance work, but also increases the infrastructure cost of the power supply site.

[0004] Therefore, how to design a bundled grounding post that can reduce infrastructure costs and standardize the connection of multiple grounding wires is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This utility model provides a wire grounding device, which solves the technical problem that existing grounding stakes can only connect to one grounding wire, resulting in complicated grounding wire connection and laying in power-using sites.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a wire grounding device, comprising: a grounding plate and multiple connecting parts for connecting grounding wires.

[0007] The grounding plate has a grounding screw hole in the middle, and a grounding bolt is threaded into the grounding screw hole. Multiple connecting parts are arranged circumferentially around the grounding plate, and each connecting part includes a connecting box, a pressure block, a locking bolt, and a connecting plate. The connecting box is detachably connected to the grounding plate and has a locking screw hole on its top surface. The side of the connecting box away from the center of the grounding plate has a through hole for the grounding wire to pass through or exit. The pressure block is placed inside the connecting box. The locking bolt is threaded into the locking screw hole, and its screw-in end is rotatably connected to the pressure block to drive the pressure block to reciprocate along the height direction of the connecting box. The connecting plate is fixed to the connecting box and has a connecting screw hole for connecting the grounding wire. The axis of the connecting screw hole is arranged circumferentially around the grounding plate, and a connecting bolt is threaded onto it.

[0008] The beneficial effects of this utility model are:

[0009] 1. By utilizing the multiple connecting parts on the grounding plate, multiple grounding wires can be connected in a standardized manner, thereby overcoming the design defect that a traditional single grounding stake can only connect to one grounding wire and improving the standardization of connecting multiple grounding wires;

[0010] 2. Since each connection part includes a connection box, pressure block, locking bolt and connection plate, the locking bolt and pressure block can be used to press the grounding wire inserted horizontally into the connection box, and the connection bolt can be used to fix the grounding wire arranged vertically, thereby expanding the connection methods of the grounding wire and improving the adaptability of the wire grounding stake.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the top surface of the pressure block is provided with a connecting groove and a limiting ring is fixed at the opening of the connecting groove; the outer circumference of the screw-in end of the locking bolt is fitted with a fixed connecting ring and the connecting ring is rotatably connected in the connecting groove, and the top end of the connecting ring can contact the bottom end of the limiting ring to restrict the locking bolt from separating from the pressure block.

[0013] The further beneficial effect of the above is that: firstly, a connecting ring is fixed on the outer periphery of the screw-in end of the locking bolt, and then a connecting groove is set on the top surface of the pressure block. Since the groove opening of the connecting groove is fixed with a limiting ring, the connecting ring can be rotatably connected in the connecting groove, and the limiting ring can be used to prevent the connecting ring from leaving the connecting groove, thereby realizing the rotatable connection between the locking bolt and the pressure block.

[0014] Furthermore, each of the multiple connecting parts also includes a connecting stud and a locking nut, and the grounding plate is provided with multiple connecting holes along its circumference; the top end of the connecting stud is fixed to the bottom end of the connecting box and can be detachably inserted into the corresponding connecting hole; the locking nut is threadedly connected to the connecting stud and its top end can contact the bottom surface of the grounding plate.

[0015] The further beneficial effects of adopting the above method are: firstly, the connecting stud can be detachably inserted into the connecting hole, and then the locking nut can be screwed onto the connecting stud from below the grounding plate, which can improve the convenience of replacing the connecting box, adapt to grounding wires of different widths, and improve the adaptability of the wire harness grounding stake.

[0016] Furthermore, the grounding bolt, the locking bolt, the connecting bolt, and the locking nut are all fixed with fins for assisting rotation.

[0017] The further beneficial effect of adopting the above is that by using the finned plate to fix it on the locking bolt, connecting bolt or locking nut, the convenience and operability of rotating the locking bolt, connecting bolt or locking nut can be improved.

[0018] Furthermore, the inner bottom surface of the connection box is provided with a receiving groove for accommodating the grounding wire.

[0019] Furthermore, the connecting screw hole is an elongated structure arranged along the height direction of the connecting box.

[0020] The further beneficial effect of adopting the above is that the long strip-shaped arrangement of the connecting screw holes can accommodate grounding wires of different widths, thus improving the adaptability of the wire harness grounding stake. Attached Figure Description
