Description

Technical Field

[0001] The utility model relates to the technical field of insulation detection, in particular to an auxiliary tool for detecting the connectivity and insulation of cables. Background Art

[0002] Cable continuity and insulation testing is a crucial step in assessing whether a cable maintains proper insulation under normal use. This testing method not only ensures cable quality and reliability but also enables early detection of potential faults and defects, thereby preventing serious problems such as insulation breakdown and short circuits during operation. Cable continuity and insulation testing primarily involves applying voltage to verify that the cable's insulation material maintains proper insulation performance under normal operating voltages. Common cable insulation testing methods include DC insulation resistance testing, AC withstand voltage testing, and partial discharge testing. Each method has its advantages and disadvantages, and the appropriate method should be selected based on the specific situation.

[0003] However, some existing cable continuity and insulation testing tools require the cable to be suspended during use. Furthermore, when dealing with long cables, these cables often need to be folded or twisted together for ease of handling and storage. This practice not only increases the number of contact points between cables but also causes increased local pressure, thus affecting the accuracy of test results. To address these shortcomings, a cable continuity and insulation testing tool was proposed to address these issues. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figures 2 to 4 The utility model provides an embodiment: a cable connectivity insulation detection auxiliary device, including a bottom frame 1, which is the basic frame structure of the entire cable connectivity insulation detection auxiliary device. A fixed frame 2 is fixedly connected to the top right side of the bottom frame 1, and a sliding frame 3 is slidably connected to the top left side of the bottom frame 1. The outside of the fixed frame 2 is slidably connected to the inside of the sliding frame 3. The sliding frame 3 cooperates with the fixed frame 2 to adjust the distance between the fixed frame 2 and the sliding frame 3 to adapt to cables of different lengths. The inside of the fixed frame 2 and the sliding frame 3 are both slidably connected to a fixed ring 4, and the outside of the two fixed rings 4 are both fixedly connected to a rubber ring 5. The outside of the rubber ring 5 is slidably connected to the inside of the sliding frame 3. The outside of the rubber ring 5 is slidably connected to the inside of the fixed frame 2. The far sides of the two fixed rings 4 are fixedly connected to two connecting plates 6, and the far sides of the multiple connecting plates 6 are fixedly connected to a connecting frame 7. The connecting plate 6 plays the role of connecting the fixed ring 4 and the connecting frame 7.

[0033] A handle 11 is fixedly connected to the far side of the multiple connecting plates 6. By pressing the handle 11, the connecting plates 6, the fixing ring 4 and the rubber ring 5 can be displaced, so that the cable can be placed inside the rubber ring 5 to achieve the fixing operation of the cable. The operation is simple and convenient, which improves work efficiency. A slide groove 12 is provided inside the fixed frame 2. The front sides of the fixed frame 2 and the sliding frame 3 are fixedly connected with a semi-cylinder 13. The outside of the semi-cylinder 13 is slidably connected to the inside of the slide groove 12. The front sides of the fixed frame 2 and the sliding frame 3 are fixedly connected with a winding column 14. The front side of the fixed frame 2 is fixedly connected with a fixed column 15. The shape of the semi-cylinder 13 is designed to better contact with the cable and reduce the wear of the cable during the winding and placement process. At the same time, the semi-cylinder 13 cooperates with the winding column 14, the fixing column 15 and other structures to achieve the suspension and arrangement of the cable, minimize the space occupied by the cable, and make the arrangement of the cable more neat and orderly. A plurality of threaded holes 16 are provided inside the sliding frame 3, and the internal threads of the fixing frame 2 are connected to two fixing bolts 17, and the external threads of the fixing bolts 17 are connected to the inside of the threaded holes 16. The fixing bolts 17 adjust the spacing by cooperating with different threaded holes 16, which can ensure that after the spacing is adjusted, the connection between the fixing frame 2 and the sliding frame 3 is firm and stable, and will not become loose or displaced during use, thereby ensuring the smooth progress of cable fixation and detection.

[0034] Reference Figures 3 to 5 Each of the multiple connecting frames 7 is provided with an elastic assembly for resetting. Each of the elastic assemblies includes a sliding rod 8. The proximal sides of the multiple sliding rods 8 are fixedly connected to the exterior of the fixed frame 2 and the sliding frame 3, respectively. The exteriors of the multiple sliding rods 8 are slidably connected to the interiors of the multiple connecting frames 7. A spring 9 is sleeved on the exterior of each of the sliding rods 8. The sliding rod 8 provides a guide for the extension and contraction of the spring 9, ensuring that the spring 9 can move in a fixed direction during the extension and resetting process, thereby ensuring the stability and reliability of the elastic assembly. One end of the spring 9 is fixedly connected to the exterior of the connecting frame 7, and the other end of the spring 9 is fixedly connected to the exterior of the limit plate 10. During operation, when the handle 11 is pressed to cause the connecting frame 7 to move, the spring 9 is stretched and stores elastic potential energy. When the handle 11 is released, the spring 9 releases the elastic potential energy, causing the connecting frame 7 to reset, thereby achieving the cable fixing and release operation. The distal sides of the multiple sliding rods 8 are fixedly connected to the limit plate 10.

[0035] Reference Figures 1 to 3The bottom of the bottom frame 1 is rotatably connected to a rotating shaft 18, which realizes the conversion of the bottom frame 1 from a horizontal to a vertical state. The outside of the rotating shaft 18 is fixedly connected to a placement frame 19, and the inside of the placement frame 19 is slidably connected to two limit frames 20. The inside of the placement frame 19 is provided with two limit slots 21, and the outside of the limit frames 20 is slidably connected to the inside of the limit slots 21. The outside of the two limit frames 20 is fixedly connected to a protective shell 22, and the inside of the protective shell 22 is slidably connected to the outside of the placement frame 19. The design of the placement frame 19 not only provides a storage space for the bottom frame 1, but also realizes the sliding connection and limitation of the protective shell 22 through the cooperation of the limit frames 20 and the limit slots 21, so that the protective shell 22 can slide on the placement frame 19 to shield and protect the bottom frame 1, protecting the bottom frame 1 and the structure thereon from damage when not in use, and also improving the portability of the entire detection auxiliary device.

[0036] Working principle: When it is necessary to use this cable connectivity insulation detection aid, the protective shell 22 can be pulled open first. At this time, the limit frame 20 will slide inside the limit groove 21, so that the inside of the placement frame 19 can be displayed, and then the fixed frame 2 and the sliding frame 3 can be manually lifted to rotate the bottom frame 1 around the rotation axis 18. At this time, the bottom frame 1 will change from a horizontal state to a vertical state, and then the protective shell 22 can be slid again, and the bottom frame 1 can be supported by the protective shell 22. Then, the handle 11 can be pressed to displace the connecting plate 6. At this time, the fixing ring 4 and the rubber ring 5 will be displaced so that one end of the cable can be placed inside the rubber ring 5. At this time, the connecting frame 7 will be displaced and the spring 9 will be pulled. Stretch, when the cable is put in, loosening the handle 11 will reset the connecting frame 7, and the elastic force of the spring 9 will be used to fix one end of the cable. The position of the fixing bolt 17 can then be adjusted according to the length of the cable, so that the spacing between the fixing frame 2 and the sliding frame 3 can be changed to adapt to cables of different lengths. The cable can then be passed around the winding column 14, the semi-cylinder 13, and the fixed column 15 to suspend the cable, while minimizing the space occupied by the cable. The above operation can then be repeated to fix the other end of the cable on the other side, and then the insulation of the cable can be tested. After the test, the bottom frame 1 can be put back into the placement frame 19 and shielded by the protective shell 22, which is easy to carry.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
