Description

Technical Field

[0001] This utility model relates to the field of grounding electrode technology, and in particular to a spiral grounding electrode that can be quickly connected. Background Technology

[0002] A grounding electrode is a metal conductor buried in soil or concrete and in direct contact with the earth, serving to dissipate current. Sufficient contact area must be maintained between the grounding electrode and the grounding wire to facilitate current conduction.

[0003] In existing technologies, the most common connection method between the grounding electrode and the grounding wire is welding, which ensures the contact area at the connection point. However, the welding process is relatively inconvenient. Simply fixing the grounding wire with screws cannot guarantee the contact area. Usually, a specific connector needs to be installed at one end of the grounding wire, which makes the whole process cumbersome. It is always difficult to balance quick connection and sufficient contact. Utility Model Content

[0004] The purpose of this invention is to provide a quick-connect spiral grounding electrode that can quickly connect to the grounding wire while ensuring sufficient contact area between the two.

[0032] Combination Figures 1 to 6 As shown, the present invention provides a quick-connect spiral grounding electrode comprising a conductive block 1, a mounting block 2, and an assembly screw 3.

[0033] Combination Figures 1 to 6 As shown, conductive block 1 and mounting block 2 are made of different materials. Conductive block 1 needs to undertake the discharge task, so copper metal block is the mainstream choice. Mounting block 2 needs to withstand the impact during use, and at the same time, it needs to ensure the integrity of its threads, so steel metal block is the mainstream choice. The material of mounting screw 3 is generally steel, following the choice of mounting block 2. The grounding electrode assembled by multiple materials can take into account both structural strength and conductivity.

[0034] The conductive block 1 is a vertically placed columnar body. A downward-through mounting groove 11 is integrally formed on the top surface of the conductive block 1 for assembling the mounting block 2. An expansion groove 12 is formed on the side wall of the mounting groove 11. The size of the expansion groove 12 corresponds to the size of the grounding wire, ensuring that the grounding wire can be pressed into it after bending. The shapes of the two do not need to be exactly the same, because the copper grounding wire will undergo slight deformation under pressure to adapt to the shape of the expansion groove 12, ensuring the contact area between them. A positioning hole 13 is integrally formed on the cylindrical surface of the conductive block 1, horizontally connecting to the mounting groove 11. The position of the positioning hole 13 is aligned with the position of the expansion groove 12, and the grounding wire enters through the positioning hole 13.

[0035] In some embodiments, combined with Figure 4 , Figure 6 As shown, an arc transition surface is provided between the positioning hole 13 and the expansion slot 12. The grounding wire will bend at this transition surface. The arc transition surface can guide the bending process of the grounding wire and avoid the grounding wire from breaking due to excessive bending angle at a single position.

[0036] Mounting block 2 is fixedly assembled in mounting groove 11. Mounting block 2 has a threaded hole 22 integrally formed in the vertical direction. The size of threaded hole 22 is larger than that of positioning hole 13, so as to reduce the destructive force of cutting edge 21 on threaded hole 22. Mounting block 2 has cutting edge 21 cutting threaded hole 22 in the vertical direction. The width of the cut section of threaded hole 22 is larger than that of positioning hole 13. At the same time, the position of cutting edge 21 and the position of expansion groove 12 correspond to each other to ensure that grounding wire can enter threaded hole 22 from cutting edge 21.

[0037] In some embodiments, combined with Figure 1 , Figure 3As shown, the upper end of the mounting block 2 is integrally formed with a top block 23, which is penetrated by a threaded hole 22 and covers the top surface of the conductive block 1; the lower end of the mounting block 2 is integrally formed with a conical block 24, the upper end of which covers the bottom surface of the conductive block 1 and the lower end is conical. The top block 23 and the conical block 24 can protect the conductive block 1 from both ends, reducing the possibility of deformation of the conductive block 1 under stress, and at the same time, can make the mounting block 2 with better structural strength after the cut edge 21 is opened.

[0038] The mounting screw 3 is fitted into the threaded hole 22. The grounding wire passes through the positioning hole 13 and extends into the threaded hole 22. The mounting screw 3 is screwed in, causing the head of the grounding wire to bend and pressing the bent head of the grounding wire into the expansion groove 12. The top surface of the tail end of the mounting screw 3 can be set as a raised spherical surface to improve the collision between the mounting screw 3 and the grounding wire during the screwing process, reduce damage to the grounding wire, and better guide the grounding wire to bend.

[0039] In some embodiments, combined with Figure 1 , Figure 4 As shown, the conductive block 1 can have multiple positioning holes 13. The positioning holes 13 on the conductive block 1 can be evenly distributed along the vertical direction. The positioning holes 13 on the same straight line in the vertical direction are connected to the same expansion groove 12 and threaded hole 22. During the distribution along the vertical direction, it is necessary to control the spacing between the holes to avoid the grounding wires on the upper side from being bent and affecting the grounding wires on the lower side. Generally, it is sufficient to control the spacing between the positioning holes 13 to be no less than the diameter of the threaded hole 22. The conductive block 1 can be symmetrically provided with two expansion grooves 12 and positioning holes 13, and the mounting block 2 is also symmetrically provided with two cut edges 21 to increase the number of positioning holes 13 and increase the wiring capacity of the entire grounding electrode. At the same time, no matter how the number of grounding wires changes, only one mounting screw 3 needs to be screwed in to complete the connection.

[0040] Working process: Insert the grounding wire into the positioning hole 13. The grounding wire then passes through the expansion groove 12 and the cut edge 21 in sequence and finally enters the threaded hole 22. When there are multiple grounding wires, each grounding wire is inserted through a different positioning hole 13.

[0041] Then, the mounting screw 3 is screwed in. During this process, the mounting screw 3 passes through each positioning hole 13 sequentially, bending the portion of the grounding wire extending into the threaded hole 22. The bent portion of the grounding wire is pressed into the corresponding expansion slot 12. Simultaneously, due to the hardness difference between the copper grounding wire and the mounting screw 3, the threads on the mounting screw 3 are imprinted on the grounding wire, improving the fixing effect on the bent portion. Furthermore, because the mounting screw 3 is screwed in and out via its threads, it does not cause excessive stretching of the grounding wire. After the mounting screw 3 is fully screwed in, all grounding wires are connected.

[0042] After the conductive block 1 and the mounting block 2 are buried in the ground, the current is introduced through the grounding wire. The end of the grounding wire is pressed tightly against the side wall of the expansion groove 12 on the conductive block 1. At the same time, the conductive block 1 is located on the outermost side of the entire grounding electrode. The conductive block 1 can directly and quickly introduce the current of the grounding wire into the ground.

[0043] In this embodiment, the grounding wire is fixed by the mounting screw 3, ensuring a simple fixing process and achieving quick connection. By setting a tangent 21 on the mounting block 2, the head of the grounding wire is automatically bent and pressed into the expansion groove 12 after being squeezed by the mounting screw 3. The side wall of the expansion groove 12 and the grounding wire are in full contact to ensure sufficient contact area, thus achieving both quick connection and sufficient contact between the grounding wire and the grounding electrode.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
