Description

Technical Field

[0001] The utility model relates to the technical field of grounding wire connection equipment, in particular to a grounding wire head. Background Art

[0002] In the power system, the inspection and maintenance of high-voltage wires fall under the category of high-altitude operations. Since high-voltage wires have high voltage electricity, for the safety of the workers, the high-voltage wires need to be grounded first, and then inspected and repaired. This can protect the safety of the workers.

[0003] At present, the tools for grounding high voltage on the market are mainly grounding wires. The structure of ordinary grounding wires is relatively simple. The grounding wires include: grounding pins, wire end plates, and wires. When the high-voltage wires need to be grounded, the wire end plates are connected to the wires, and the grounding pins are inserted into the ground, so that the high-voltage wires can be grounded and the safety of the staff can be ensured.

[0004] Existing grounding devices, such as the Chinese patent document with publication number CN219610767U, discloses an electric grounding pile, which records that "the surface of the grounding pile body is provided with a rotating block, the inner side of the rotating block is provided with a first rotating hole, both sides of the first rotating hole are provided with first card slots, the inner side of the first card slot is provided with a first card block, and one end of the first card block is provided with a first rotating shaft." The electric grounding pile is installed with an integrated rotating block, which can effectively integrate it with the grounding pile body, making it impossible for non-staff to directly see and adjust the rotating block.

[0005] For another example, the Chinese patent document with publication number CN221262733U discloses an electric grounding pile, which records that "it includes a top rod, a middle rod is provided at the bottom of the top rod, a bottom rod is provided at the bottom of the middle rod, threaded columns are fixed to the bottoms of the top rod and the middle rod respectively, the top rod, the middle rod and the bottom rod are connected to each other through the threaded columns, and a pair of sliders are fixed on the middle side walls of the top rod, the middle rod and the bottom rod; the bottom of the bottom rod is fixedly connected to a pile head, and a plurality of rotary fans are evenly installed on the top of the pile head around the circumference". The electric grounding pile is provided with a pile head, a rotary fan, a concave section, a special-shaped slide groove and a slider and other structures that cooperate with each other, so that the flat barbs are unfolded at the bottom after the grounding pile enters the ground, thereby improving the stability of the grounding pile.

[0006] However, the following defects or problems still exist in combination with the existing technology: However, during the use of the above-mentioned wire end plate, the wire end plate is directly welded to the grounding pin. Since there is only one welding surface, the welding stability is poor; secondly, in order to ensure a firm welding between the grounding pin and the wire end plate, a groove needs to be opened on the welding edge of the elbow plate, but the additional production process of opening the groove on the elbow plate increases the production cost. At the same time, the welding wire is easily melted into the outer surface of the elbow plate during welding, and it needs to be polished after welding, and the welding strength is low. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] As attached Figure 1 To the attached Figure 3 As shown:

[0024] A grounding wire end includes a grounding pin 1 and a handle 2. The grounding pin 1 and the handle 2 are connected vertically to each other. A wire end plate 3 is provided at one end of the grounding pin 1 close to the handle 2. The wire end plate 3 is rectangular. A first protrusion 4 is provided on the outer wall of one side of the wire end plate 3. The first protrusion 4 contacts the outer wall of the handle 2. A second protrusion 5 is provided on the outer wall of the other side of the wire end plate 3. The second protrusion 5 contacts the outer wall of the grounding pin 1. The first protrusion 4, the second protrusion 5 and the wire end plate 3 are integrally formed. A threaded hole is provided on the outer wall of the wire end plate 3. A wiring bolt 8 is threadedly connected to the threaded hole of the wire end plate 3. The wire is wrapped around the wiring bolt 8, and then the wiring bolt 8 is tightened. The wiring bolt 8 is used to fix the grounding wire.

[0025] The first protrusion 4 and the second protrusion 5 are both triangular structures. The contact surface between the first protrusion 4 and the handle 2 is the sharp corner of the triangle, and the contact surface between the second protrusion 5 and the grounding pin 1 is the sharp corner of the triangle. The side of the thread end plate 3 close to the handle 2 and the side of the thread end plate 3 close to the grounding pin 1 are both welding edges. A first weld bead 6 is arranged between the handle 2 and the thread end plate 3, and a second weld bead 7 is arranged between the grounding pin 1 and the thread end plate 3. The height of the first protrusion 4 and the second protrusion 5 is the width of the first weld bead 6 and the second weld bead 7. Chamfers 9 are arranged at the four corners of the thread end plate 3. The surface of the thread end plate 3 is a smooth plane, and the thickness of the thread end plate 3 is 5mm-10mm.

[0026] The specific usage and function of this embodiment are as follows:

[0027] When the present invention is used, the thread end plate 3 is cut and formed by laser cutting technology, and a first convex head 4 and a second convex head 5 are reserved on the thread end plate 3. The first convex head 4 and the second convex head 5 are both triangular structures. The contact surface between the first convex head 4 and the handle 2 is in contact at the sharp corner of the triangle, and the contact surface between the second convex head 5 and the grounding pin 1 is in contact at the sharp corner of the triangle. The side of the thread end plate 3 close to the handle 2 and the side of the thread end plate 3 close to the grounding pin 1 are both welding edges.
