Description

Technical Field

[0001] This utility model relates to the field of wiring device technology, and in particular to an improved high-voltage power test wiring device. Background Technology

[0002] In power systems, high-voltage testing is a crucial step in ensuring the safe and stable operation of power equipment and the reliable power supply of the grid. By conducting high-voltage tests on power equipment, potential insulation defects, aging problems, and other safety hazards can be detected in a timely manner. This allows for targeted maintenance measures to be taken, preventing equipment failures during operation, reducing power outages, and ensuring the continuity of power supply.

[0003] In high-voltage testing, the wiring device plays a crucial role, serving as a vital bridge connecting the testing equipment to the tested wire. Its performance directly impacts the accuracy, safety, and efficiency of the test. However, traditional high-voltage power testing wiring devices typically employ fixed-specification clamping structures, with the upper and lower clamps having fixed dimensions and shapes. This means that such wiring devices can only accommodate wires of specific sizes and specifications, lacking sufficient applicability. Furthermore, most traditional high-voltage power testing wiring devices lack effective safety protection measures, with the wiring points exposed, resulting in inadequate safety performance. For example, patent CN215005533U, entitled "An Improved High-Voltage Power Testing Wiring Device," suffers from the aforementioned problems. Therefore, an improved high-voltage power testing wiring device needs to be designed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an improved high-voltage power test wiring device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An improved high-voltage power test wiring device includes a base plate, a connecting seat fixed at the upper end of the base plate, mounting grooves at both ends of the connecting seat, a clamping mechanism inside the mounting groove, the clamping mechanism including an upper clamping block and a lower clamping block disposed inside the mounting groove, clamping grooves on the side walls of the upper and lower clamping blocks that are close to each other, a threaded rod threadedly connected to the connecting seat through the inner top wall of the mounting groove, a rotating block fixedly connected to the upper end of the threaded rod, an insertion hole for cooperating with the threaded rod at the upper end of the upper clamping block, and a protective mechanism connected to the upper end of the base plate.

[0007] As a further improvement of this utility model, the protective mechanism includes a protective shell, which is hinged to the upper end of the base plate. A connecting block is fixedly connected to the side wall of the protective shell away from the hinge. A connecting bolt is threaded through the connecting block and screwed into it. The upper end of the base plate is provided with a connecting screw hole that mates with the connecting bolt.

[0008] As a further improvement of this utility model, slots are provided on both sides of the mounting groove, and a locking block is fixedly connected to both sides of the upper and lower clamping blocks, with the locking block disposed inside the slot.

[0009] As a further improvement of this utility model, the base plate is provided with grooves at both ends near the mounting groove.

[0010] As a further improvement of this utility model, mounting holes are provided through the four corners of the upper end of the base plate.

[0011] As a further improvement of this utility model, a weight reduction hole is provided through the side wall of the connecting seat.

[0012] The beneficial effects of this utility model are:

[0013] By setting up detachable upper and lower clamping blocks, users can quickly replace upper and lower clamping blocks of different specifications without replacing the entire device. Simply replacing the upper and lower clamping blocks is enough to adapt to wires of different sizes and specifications, solving the problem of low adaptability caused by the single wire diameter of traditional wiring devices.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figures 1-3 An improved high-voltage power test wiring device includes a base plate 1. Mounting holes 2 are provided at the four corners of the upper end of the base plate 1. A connecting seat 8 is fixed to the upper end of the base plate 1. Weight reduction holes 9 are provided through the side walls of the connecting seat 8. Mounting grooves 10 are provided at both ends of the connecting seat 8. A clamping mechanism is provided inside the mounting groove 10. The clamping mechanism includes an upper clamping block 14 and a lower clamping block 16 disposed inside the mounting groove 10. Clamping grooves 17 are provided on the side walls of the upper clamping block 14 and the lower clamping block 16 that are close to each other. A screw 12, threadedly connected to the connecting seat 8, is provided through the inner top wall of the mounting groove 10. The upper end of the screw 12 is fixed... A rotating block 13 is fixedly connected. The upper end of the upper clamping block 14 is provided with a socket 15 that mates with the screw 12. After the wire to be connected is stripped, it is inserted between the upper clamping block 14 and the lower clamping block 16. Then, the screw 12 is inserted into the socket 15. By rotating the screw 12, since the screw 12 is screwed to the connecting seat 8, the screw 12 can be moved. The movement of the screw 12 presses the upper clamping block 14. The upper clamping block 14 and the lower clamping block 16 can clamp and fix the wire. The upper end of the base plate 1 is connected to a protective mechanism. Both ends of the base plate 1 near the mounting groove 10 are provided with grooves 3 to accommodate the wire.

[0021] In this utility model, the protective mechanism includes a protective shell 4, which is hinged to the upper end of the base plate 1 via a hinge 5. A connecting block 6 is fixedly connected to the side wall of the protective shell 4 away from the hinge 5. A connecting bolt 7 is threaded through the connecting block 6 and screwed into it. The upper end of the base plate 1 is provided with a connecting screw hole 19 that mates with the connecting bolt 7. After the wire is wired, the protective shell 4 is rotated and closed, and then the connecting bolt 7 is screwed into the connecting screw hole 19 to fix the protective shell 4. The protective shell 4 can play a protective role and provide a good connection environment for the wiring point.

[0022] Each of the two opposite sides of the mounting slot 10 is provided with a slot 11. Each of the two opposite sides of the upper clamping block 14 and the lower clamping block 16 is fixedly connected with a clamping block 18. The clamping block 18 is located inside the slot 11. By inserting the clamping block 18 into the slot 11, the upper clamping block 14 and the lower clamping block 16 can be installed inside the mounting slot 10. By removing the clamping block 18 from the slot 11, the upper clamping block 14 and the lower clamping block 16 can be disassembled, making it easy to replace the upper clamping block 14 and the lower clamping block 16. By presetting the size of the clamping slot 17 on different upper clamping blocks 14 and lower clamping blocks 16, it can accommodate the clamping of wires of different sizes. Thus, by using the required upper clamping block 14 and lower clamping block 16, wires of different sizes can be clamped, making it more adaptable.

[0023] When using this utility model, the operator first selects the appropriate upper clamping block 14 and lower clamping block 16 according to the diameter of the wire to be clamped, so that the size of the clamping groove 17 matches the size of the wire. Then, the upper clamping block 14 and lower clamping block 16 are respectively inserted into the mounting grooves 10 at both ends of the connector 8, ensuring that the locking blocks 18 on the opposite side walls of the upper clamping block 14 and lower clamping block 16 are aligned and locked into the locking grooves 11 on the side walls of the mounting groove 10, so that it is stably positioned in the mounting groove 10.

[0024] After stripping the insulation from the ends of the two wires to be connected, they are placed in the mounting slots 10 at both ends, positioning the wires in the clamping groove 17 between the upper clamping block 14 and the lower clamping block 16. Once positioned, the rotating block 13 drives the screw 12 to rotate. Since the screw 12 is threaded to the top wall of the connecting seat 8, and its lower end is inserted into the insertion hole 15 at the top of the upper clamping block 14, the screw 12 rotates vertically downwards, pushing the upper clamping block 14 vertically downwards along the inner wall of the mounting groove 10. This downward pressure causes the upper clamping block 14 and the lower clamping block 16 to move together... The wires are clamped in the clamping groove 17. The contour of the clamping groove 17 fits tightly with the wires to form a reliable electrical connection and mechanical fixation. After the wires at both ends are firmly clamped in this way, the wires are straightened so that they are embedded in the grooves 3 at both ends of the base plate 1. Then, the protective shell 4 is rotated around the hinge 5 to close and cover the base plate 1, so that the connecting seat 8 and the wiring point are covered. Finally, the connecting bolt 7 that passes through the connecting block 6 that is fixed to the side wall of the protective shell 4 is screwed into the corresponding connecting screw hole 19 at the upper end of the base plate 1 to lock the protective shell 4 and form a protective space.

[0025] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
