Description

Technical Field

[0001] This utility model relates to the field of current technology, specifically a cylindrical current branching device. Background Technology

[0002] In power distribution systems, communication base stations, and new energy equipment (such as photovoltaic arrays and energy storage systems), cable branch connections are a crucial link in ensuring stable current transmission. Traditional branch connections also have the following drawbacks: using insulated piercing clamps for branching can easily loosen during vibration, potentially leading to branch point meltdown accidents. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a cylindrical current branching device.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a cylindrical current branching device, including a wire fixing body. One end of the wire fixing body is provided with a locking screw, and the end of the locking screw has a cable groove for threading the wire. The main cable passes through the cable groove. A locking nut that is threadedly connected to the locking screw is sleeved on the outside of the locking screw. A branch slot hole is provided on the wire fixing body, and a branch cable passes through the branch slot hole. A branch tightening slot hole is provided on the wire fixing body, which is connected to the branch slot hole and the cable groove. An elastic bolt for tightening the branch cable and the main cable is embedded in the branch tightening slot hole.

[0006] As a preferred technical solution of this utility model, the end of the branch clamping slot facing the locking screw is provided with a V-shaped groove.

[0007] As a preferred embodiment of this utility model, the locking screw and the wire fixing body are integrally formed.

[0008] As a preferred embodiment of this utility model, the elastic bolt is a telescopic elastic bolt.

[0009] As a preferred technical solution of this utility model, the locking nut is provided with a limiting clamping block that cooperates with the cable groove. The limiting clamping block is either T-shaped or I-shaped.

[0010] The beneficial effects of this utility model are:

[0011] This cylindrical current branching device forces the main cable toward the line fixing body by rotating the locking nut, and then presses the main cable tightly against the line fixing body. At the same time, the elastic bolt is pressed against the branch cable and the main cable. The elastic bolt provides a double pressing effect, forming a current branching working state. This facilitates the simultaneous tightening of the main cable and the branch cable, improving the applicability of the current branching device. It avoids the current use of insulation piercing clamps for branching, which are prone to loosening during vibration and may cause the branch point to melt and break. This improves stability.

[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0017] Example: Figure 1 and Figure 2As shown, this utility model discloses a cylindrical current branching device, including a wire fixing body 1. One end of the wire fixing body 1 is provided with a locking screw 2. A cable groove 3 for threading a wire is opened at the end of the locking screw 2. A main cable 4 passes through the cable groove 3. A locking nut 5, threadedly connected to the locking screw 2, is fitted onto the outside of the locking screw 2. A branch slot hole 6 is opened on the wire fixing body 1. A branch cable 7 passes through the branch slot hole 6. A branch tightening slot hole 8, communicating with the branch slot hole 6 and the cable groove 3, is opened on the wire fixing body 1. A branch tightening slot hole 8 is embedded inside the branch cable tightening slot hole 8. The elastic bolt 9, which tightens the main cable 4 and the branch cable 7, forces the main cable 4 to move towards the line fixing body 1 through the rotation of the locking nut 5. After the main cable 4 is close to the line fixing body 1, it is pressed tightly. At the same time, the elastic bolt 9 is pressed tightly against the branch cable 7 and the main cable 4. The setting of the elastic bolt 9 plays a double pressing role, forming a current branch working state. It is convenient to tighten the main cable 4 and the branch cable 7 at the same time, which improves the applicability of the current branching device. It avoids the current use of insulation piercing clamps for branching, which is prone to loosening during vibration, which may lead to the branch point melting accident. It improves stability.

[0018] The branch clamping slot 8 has a V-shaped groove 10 at one end facing the locking screw 2, which can be used to clamp main cables 4 with different outer diameters.

[0019] The locking screw 2 is integrally formed with the wire fixing body 1, resulting in higher strength and a longer service life.

[0020] The elastic bolt 9 is a retractable elastic bolt, which can provide good protection for the branch cable 7 and the main cable 4.

[0021] The locking nut 5 has a limiting clamping block 11 inside that cooperates with the cable groove 3. The limiting clamping block 11 is either T-shaped or I-shaped. When the locking nut 5 is turned, the limiting clamping block 11 clamps the main cable 4. The limiting clamping block 11 is preferably T-shaped. It clamps the main cable 4 while turning, which is also convenient for disassembly and assembly, and thus facilitates the replacement of damaged limiting clamping blocks 11.

[0022] During operation, the rotation of the locking nut 5 forces the main cable 4 to move toward the wire fixing body 1 and presses it tightly after the main cable 4 comes into close contact with the wire fixing body 1. At the same time, the elastic bolt 9 is pressed tightly against the branch cable 7 and the main cable 4. The setting of the elastic bolt 9 plays a double pressing role, forming a working state of current branching. This makes it easy to tighten the main cable 4 and the branch cable 7 at the same time, improving the applicability of the current branching device. It avoids the current use of insulation piercing clamps for branching, which are prone to loosening during vibration, which may lead to the branch point melting accident, thus improving stability.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
