Abstract
Description
Technical Field
[0001] This application relates to the technical field of cable withstand voltage testing, and in particular to an adjustable high-frequency spark tester. Background Technology
[0002] The high-frequency spark tester uses the principle of LC oscillation to generate a fixed frequency test voltage, which applies a voltage of 2500-3500 times to the test wire. High voltage is applied to the moving test specimen through the beaded electrode. Under the condition that the test specimen conductor is grounded, when there is a defect in the test specimen insulation, a spark will be generated in the insulation, thereby detecting the defect. It is suitable for online insulation withstand voltage spark testing of various wires and cables, electronic wires, electronic parallel wires, and FFC flexible flat wires.
[0003] Cables produced in the factory require withstand voltage testing for safe use in some cases, but some cables are not used in high-voltage applications and therefore do not require withstand voltage testing. A high-frequency spark tester mainly consists of a testing machine and a chassis, with the chassis fixedly connected to the testing machine. When dealing with cables that do not require withstand voltage testing, the high-frequency spark tester is moved to another area. When cables requiring withstand voltage testing reappear, the high-frequency spark tester needs to be moved back. Since high-frequency spark testers are typically large and heavy, this constant moving is not only time-consuming and labor-intensive but also affects overall work efficiency. Utility Model Content
[0004] To address the issue of frequent movement of the high-frequency spark tester affecting overall work efficiency during cable withstand voltage testing, this application provides an adjustable high-frequency spark tester.
[0005] The adjustable high-frequency spark testing machine provided in this application adopts the following technical solution:
[0006] An adjustable high-frequency spark testing machine includes a testing machine, a chassis, and a sliding module.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0034] The following is in conjunction with the appendix Figures 1-8 This application will be described in further detail.
[0035] This application discloses an adjustable high-frequency spark testing machine, referring to... Figure 1 It includes a testing machine 10, a housing 20, a sliding module 1, a lifting module 2, an angle adjustment module 3, and a moving module 4. The testing machine 10 is installed at the top of the high-frequency spark testing machine, the sliding module 1 is installed at the bottom of the testing machine 10, the angle adjustment module 3 is installed at the bottom of the sliding module 1, the lifting module 2 is installed at the bottom of the angle adjustment module 3, the housing 20 is installed at the bottom of the lifting module 2, and the moving module 4 is installed at the bottom of the housing 20.
[0036] Reference Figure 2 The testing machine 10 includes a housing, which includes an upper cover and a lower cover. The upper cover is hinged to the lower cover on one side. An opening 101 is provided on the housing, which passes through the upper cover and the lower cover.
[0037] Reference Figures 1-3The sliding module 1 includes a testing machine support plate 11 and a slide rail 12. The lower end of the testing machine 10 is provided with a slide groove. The slide rail 12 is welded to the upper top wall of the testing machine support plate 11. The testing machine 10 slides on the slide rail 12 through the slide groove. In this embodiment, two slide rails 12 are provided, and the two slide rails 12 are respectively provided on both sides of the long axis of the testing machine support plate 11.
[0038] The testing machine 10 is also equipped with a positioning component, which includes a set screw 13. Two set screw holes 14 are opened on each side of the short shaft of the testing machine 10 housing. The set screw holes 14 pass through the side wall of the lower end of the testing machine 10 and communicate with the slide groove. A set screw 13 is threaded into each set screw hole 14. After the testing machine 10 is moved to the preset position along the slide rail 12, the set screw 13 is rotated. The large friction force generated by the end of the set screw 13 abutting against the slide rail 12 temporarily fixes the testing machine 10 on the slide rail 12.
[0039] Reference Figures 4-5 The angle adjustment module 3 includes a ratchet support platform 15, ratchet 16, a connecting cylinder 23, and a ratchet ring 24. The ratchet support platform 15 is welded to the lower bottom wall of the inspection machine support plate 11. Six ratchet 16 are provided and welded to the ratchet support platform 15. The six ratchet 16 are arranged in a circumferential direction along the axis of the ratchet support platform 15. The connecting cylinder 23 is located below the inspection machine support plate 11. The lower end of the connecting cylinder 23 is installed on the lifting module 2. The ratchet ring 24, which is welded or glued to the connecting cylinder 23, is inserted into the six ratchet 16. The top of the ratchet ring 24 is located inside the connecting cylinder 23. The ratchet support platform 15 abuts against the upper end of the connecting cylinder 23, and the ratchet 16 is inserted into the ratchet ring 24 in the connecting cylinder 23. When the testing machine support plate 11 is rotated, the ratchet 16 at the lower end of the testing machine support plate 11 slides on the ratchet ring 24 inside the connecting cylinder 23. Since there are 6 ratchet 16 in this embodiment, after the ratchet 16 on the testing machine support plate 11 slides from one ratchet groove to another in the ratchet ring 24, the testing machine support plate 11 rotates 60° from its original position. Without the action of external force, the ratchet 16 will not slide on the ratchet ring 24. In this embodiment, the ratchet 16 adopts a sawtooth type, so it can only slide unidirectionally on the ratchet ring 24. In another embodiment, the ratchet 16 can also be set in a trapezoidal shape, and the trapezoidal ratchet 16 can slide bidirectionally on the ratchet ring 24.
[0040] Reference Figures 6-8The lifting module includes a screw 22, a lifting adjustment component 200, a fixed plate 28, a set screw 29, a support cylinder 211, and a prism 212. The lifting adjustment component 200 includes a rotary handle 21, a connecting rod 25, a rotating block 26, and a rolling element 213. The upper end of the support cylinder 211 is provided with a mating cavity 210. The prism 212 is vertically fixedly installed inside the support cylinder 211. A groove 221 is provided along the axis of the screw 22 at its axis. The screw 22 slides on the prism 212 inside the support cylinder 211 through the groove 221. The upper end of the screw 22 is fixedly connected to the connecting cylinder 23 inside the angle adjustment module 3. In this embodiment, the prism 212 is a hexagonal prism. The rotating block 26 is installed inside the mating cavity 210. Eight ball grooves are provided at both the lower and upper ends of the rotating block 26, arranged circumferentially along the axis of the rotating block 26. Each ball groove contains a rolling element 213. The rolling elements 213 at the lower end of the rotating block 26 roll on the bottom wall of the mating cavity 210. The rotating block 26 has a mating hole 27 along its axis. The screw 22 is threaded into the mating hole 27 of the rotating block 26. The fixed plate 28 is fixedly connected to the mating cavity 210 by set screws 29. On the top wall of 10, the fixed disk 28 restricts the rotating block 26 within the mating cavity 210. The rolling elements 213 set at the upper end of the rotating block 26 are all used to roll on the lower bottom wall of the fixed disk 28. The fixed disk 28 has a through hole along the axis, the diameter of which is smaller than the outer diameter of the rotating block 26. Six connecting rods 25 are welded on the rotating block 26. The six connecting rods 25 are arranged in the circumferential direction along the axis of the rotating block 26. The six connecting rods 25 pass through the through hole of the fixed disk 28 in the vertical direction and are connected to a rotating handle 21.
[0041] When it is necessary to raise or lower the support plate 11 of the testing machine, the rotary handle 21 is turned. The rotary handle 21 drives the rotating block 26 to rotate through the connecting rod 25. The rotating block 26 is connected to the screw 22 through its own mating hole 27. The rotating block 26 is restricted by the fixed plate 28 and can only rotate in the mating cavity 210. The screw 22 is restricted by the prism 212 and can only move along the axis of the prism 212. Therefore, when the rotating block 26 rotates, the screw 22 drives the support plate 11 of the testing machine and the components set on the support plate 11 of the testing machine to rise or fall along the axis of the prism 212.
[0042] Reference Figures 1-2 The mobile module 4 includes a chassis support plate 30 and casters 31. The lower end of the chassis 20 is set on the top wall of the chassis support plate 30, and a caster 31 is set at each of the four corners of the bottom wall of the chassis support plate 30.
[0043] In this embodiment, the high-frequency spark tester is moved by the universal wheels 31. The tester 10 can not only move and rotate above the chassis 20, but also move up and down above the chassis 20. The advantages of this application are as follows: the high-frequency spark tester is equipped with casters 31 at the lower end, making it easier to move; when performing withstand voltage tests on cables, if the space where the high-frequency spark tester is placed is relatively small, and it is inconvenient to adjust the overall position of the high-frequency spark tester using casters 31 after pushing it into the work area, the angle of the tester 10 can be adjusted by rotating the tester support plate 11, and then the upper cover of the tester box can be opened to insert the cable into the tester 10 through the opening 101 on one side of the tester box, and then the cable inside the tester 10 can be inserted out through the opening 101 on the other side of the tester box; when facing cables that do not require withstand voltage testing, the tester 10 can be pushed to one side from its original position on the tester support plate 11. At the same time, if the space where this device is placed is relatively small, and there are obstacles on both sides of the tester 10, so that the tester 10 cannot avoid the cable, the cable can be avoided by raising and lowering the screw 22.
[0044] The implementation principle of an adjustable high-frequency spark tester according to an embodiment of this application is as follows: When a cable needs to be tested for withstand voltage, the high-frequency spark tester is pushed into the working area, and then the height of the tester 10 is adjusted by the lifting screw 22. Then, the position of the tester 10 on the tester support plate 11 is adjusted by the sliding tester 10. After the overall position of the tester 10 is adjusted, the cable can be tested for withstand voltage. After a batch of cables that need withstand voltage testing has been tested, a batch of cables that do not need withstand voltage testing is replaced. The tester 10 is pushed to one side from its original position to allow the cables that do not need testing to pass. If there are obstacles on both sides of the tester 10, the screw 22 below the tester 10 is raised and lowered by turning the rotary handle 21 to avoid the cables. Similarly, if another batch of cables that need withstand voltage testing is replaced, the tester 10 that was pushed to one side from its original position is pushed back to its original position, or the tester 10 that was lowered is raised back up.
[0045] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
