Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, and in particular to a cable withstand voltage test platform. Background Technology

[0002] According to the patent document with publication number CN217543289U, the three battery cores in the cable are inserted into the three sockets in the multi-phase connection terminal of the three-phase wiring mechanism. By pressing down the clamping plate, the battery cores are made to make full contact with the sockets. The multiple sockets are isolated by insulating sleeves so that the withstand voltage test of each battery core is not interfered with. At the same time, the two springs between the top plate of the clamping mechanism and the test platform table are used to press down the clamping plate, so that the multiple slots on the clamping plate can independently clamp and limit the three battery cores with the three sockets on the multi-phase connection terminal, thereby performing the withstand voltage test of the cable.

[0003] When the cable end is clamped, the patent document states that because the cable is very rigid and the entire battery cell is made of multiple strands of metal wire and has a circular structure, relying solely on the spring to drive the top plate to press down the clamping plate so that the clamping slot can independently clamp and limit the three battery cells with the three sockets on the multi-phase connection terminal is obviously limited. This may result in uneven contact between some battery cells and the terminal, which may cause overheating during testing, and the overall connection stability is poor. Utility Model Content

[0004] The purpose of this invention is to provide a cable withstand voltage test platform to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A cable withstand voltage test platform includes an insulating plate, with insulating columns fixed at the four corners of the bottom of the insulating plate, support plates fixed under the four insulating columns, two symmetrical storage drawers in the middle of the support plates, and two T-shaped frames fixed on the top two sides of the insulating plate. The two T-shaped frames are provided with a pre-tightening mechanism on the side of the two T-shaped frames that are close to each other, and a clamping mechanism on the side of the two T-shaped frames that are far apart from each other. Two sliding grooves are provided at the front and rear ends of the T-shaped frames.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] like Figures 1-8As shown, a cable withstand voltage test platform includes an insulating plate 4, with insulating columns fixed at the four corners of the bottom of the insulating plate 4, a support plate 5 fixed under the four insulating columns, two symmetrically arranged storage drawers 7 in the middle of the support plate 5, two parallel L-shaped frames fixed at the middle of the top of the support plate 5, sliding bars for moving within the L-shaped frames fixed on both sides of the storage drawers 7, a push-out cylinder 8 between the two storage drawers 7, a connecting seat on the telescopic part of the push-out cylinder 8, two connecting rods 9 hinged to the lower side of the connecting seat, the end of the connecting rod 9 away from the connecting seat being hinged to the end of the storage drawer 7, a lifting mechanism 6 on the lower side of the support plate 5, and two T-shaped frames 1, which are fixed to the top two sides of the insulating plate 4 respectively. A pre-tightening mechanism 2 is provided on the side of the two T-shaped frames 1 that is close to each other, and a pressing mechanism 3 is provided on the side of the two T-shaped frames 1 that is far from each other. Two sliding grooves are opened at the front and rear ends of the T-shaped frames 1.

[0029] In this embodiment: the pre-tightening mechanism 2 includes a lower cable frame 22, which is fixed to the top of the insulating plate 4. An upper cable frame 21 is provided on the upper side of the lower cable frame 22. A first spring 23 is fixed to the top of the upper cable frame 21. Both ends of the upper cable frame 21 are fixed with protrusions that slide in the groove. The first spring 23 pushes the upper cable frame 21 to move downward along the groove of the T-shaped frame 1, thereby pressing and fixing the cable end to the lower cable frame 22 through the upper cable frame 21, which facilitates the withstand voltage test of the cable.

[0030] In this embodiment: the clamping mechanism 3 includes a support contact plate 37, and a cable contact plate 36 is provided on the upper side of the support contact plate 37. Both ends of the cable contact plate 36 are provided with support rods passing through the ends of the T-shaped frame 1. A pull rod 35 is provided at one end of the support rod extending out of the T-shaped frame 1. The lower end of the pull rod 35 is hinged to the upper end of the movable frame 32. A cable contact frame 33 is provided on the side of the movable frame 32 away from the T-shaped frame 1. Multiple sets of cable contact pin trays 34 are provided on the cable contact frame 33. The support contact plate 37 is fixedly connected to the insulating plate 4. A circular notch is provided on the side of the cable contact plate 36 that is close to it, and an arc-shaped through hole is provided on the T-shaped frame 1. A second spring is provided between the cable contact frame 33 and the movable frame 32. Two T-shaped sliders are provided on the lower side of the cable contact frame 33, and T-shaped grooves for the movement of the T-shaped sliders are provided on both sides of the top of the insulating plate 4. Through grooves for the sliding of the cable contact frame 33 are provided on both sides of the top of the insulating plate 4. A double telescopic cylinder 31 is provided between the two movable frames 32. The double telescopic cylinder 31 is located at the bottom of the insulating plate 4. A guide groove for the sliding of the cable contact plate 36 support rod is provided at the upper end of the pull rod 35. The retraction of the telescopic part of the double telescopic cylinder 31 drives the two movable frames 32 to move closer to each other. The movement of the movable frame 32 pulls the cable contact frame 33 along the T-shaped groove towards the end of the cable through the second spring. Then, multiple sets of cable contact pins 34 on the cable contact frame 33 are inserted into the end of the cable. At the same time, the movement of the movable frame 32 will drive the pull rod 35 to move synchronously. During this process, the pull rod 35 will move synchronously with the movable frame 32. Furthermore, the support rod at the end of the cable contact plate 36 will slide in the guide groove of the pull rod 35. When the cable contact frame 33 is pressed against the cable end, the upper end of the guide groove of the pull rod 35 will pull the cable contact plate 36 to move downward along the slide groove of the T-shaped frame 1, thereby pressing the cable contact plate 36 on the upper side of the cable end. Then, under the support of the support contact plate 37, the cable end with the cable contact pin 34 inserted is pressed onto the support contact plate 37 by the cable contact plate 36, thereby completing the conductive connection of the entire cable end.

[0031] In this embodiment, the lifting mechanism 6 includes two sets of support legs, which are located on both sides of the support plate 5. Each set of support legs consists of a lifting bracket 61 and a rotating wheel 63. The lifting bracket 61 and the rotating wheel 63 are rotatably connected. A crossbar is provided between the two lifting brackets 61 on the same side, and the two lifting brackets 61 and the crossbar form an I-shaped structure. The upper end of the lifting bracket 61 is rotatably connected to the support plate 5. A double telescopic cylinder 31 is hinged on the crossbar. The upper end of the double telescopic cylinder 31 is hinged to the end of the support plate 5. The telescopic part of the lifting cylinder 62 pushes the crossbar of the two lifting brackets 61 to flip downward, thereby causing the lower end of the lifting bracket 61 to flip with its upper end as the center, thereby raising the height of the support plate 5.

[0032] Working principle: When in use, first insert both ends of the cable that needs to withstand the pressure test between the upper cable frame 21 and the lower cable frame 22, and let the cable end pass through the T-shaped frame 1 and be placed on the upper side of the support contact plate 37. At this time, the first spring 23 pushes the upper cable frame 21 to move downward along the slide groove of the T-shaped frame 1, and then the downward movement of the upper cable frame 21 presses the cable onto the lower cable frame 22.

[0033] Subsequently, the telescopic section of the double telescopic cylinder 31 retracts, causing the two movable frames 32 to move closer together. The movement of the movable frames 32 drives the pull rod 35 to move synchronously. At the same time, the second spring drives the cable contact frame 33 to move closer to the cable end along the T-slot. The movement of the cable contact frame 33 inserts multiple sets of cable contact pins 34 into the cable end that is pressed by the upper cable frame 21 and the lower cable frame 22. Simultaneously, the support rod on the cable contact plate 36 moves along the guide groove on the pull rod 35. When the cable contact pins 34 no longer insert into the cable end, the second spring... The spring begins to stretch, and at the same time, the upper side of the guide groove of the pull rod 35 drives the support rod of the cable contact plate 36 to move downward. The downward movement of the cable contact plate 36 presses the end of the cable with the cable contact pin 34 inserted. During this process, the power is connected through the cable contact plate 36, the support contact plate 37 and the cable contact pin 34, thereby increasing the contact area of ​​the entire cable and avoiding the occurrence of loose connection or cable loosening during the withstand voltage test, which would result in the cable not being pressed tightly. Then, different voltages are slowly supplied to the cable to facilitate the withstand voltage test of the cable.

[0034] Meanwhile, the entire test platform can store items through the storage drawer 7, and the extension or retraction of the telescopic part of the push-out cylinder 8 can drive the two connecting rods 9 to close or open, thereby sliding the two storage drawers 7 along the L-shaped frame at the top of the support plate 5.

[0035] When it is necessary to adjust the height of the entire test platform, the extension part of the lifting cylinder 62 extends and pushes the crossbar to make the lifting bracket 61 flip downward, and then the height of the entire test platform is raised by the flipped lifting bracket 61.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
