Description

Technical Field

[0001] This utility model belongs to the field of high-voltage wire harness testing technology, specifically relating to a high-voltage wire harness shielding tester. Background Technology

[0002] A high-voltage wire harness shielding tester is an instrument specifically designed to test the shielding performance of high-voltage wire harnesses. Through specific testing principles and methods, it quantitatively evaluates the shielding effect of high-voltage wire harnesses to determine whether they meet relevant standards and usage requirements. This ensures that high-voltage wire harnesses can effectively prevent the leakage and intrusion of electromagnetic interference during the transmission of electrical energy and signals, thereby guaranteeing the normal operation of equipment and the safety of the electromagnetic environment.

[0003] However, during long testing operations, the fixed height and angle of the testing instrument cause great difficulties for the staff's observation. The staff are forced to maintain unnatural postures such as bending over, turning to the side, and craning their necks for a long time, trying their best to get close to the testing instrument in order to clearly see the data, wiring harness, and equipment connection status on the display screen. Over time, this will not only cause the body to quickly fall into a state of fatigue, causing discomfort symptoms such as muscle soreness and neck stiffness, but also, over time, may cause irreversible damage to the staff's spine and cervical spine and other critical parts, seriously threatening their health.

[0004] To address the aforementioned issues, this application proposes a high-voltage wire harness shielding tester. Utility Model Content

[0022] Please see Figure 1-4 The present invention provides the following technical solution: a high-voltage wire harness shielding tester, including a base plate 1, a support plate 2, a tester 3, a controller 6 and two sets of telescopic columns 4 respectively arranged on the top of the base plate 1, an electric push rod 11 fixedly connected to the upper surface of the base plate 1, the telescopic end of the electric push rod 11 fixedly connected to the bottom surface of the support plate 2, a fixed frame 14 fixedly connected to the upper surface of the support plate 2, a connecting frame 15 rotatably connected to the inner wall of the fixed frame 14, the upper surface of the connecting frame 15 fixedly connected to the bottom surface of the tester 3, a brake motor 13 is arranged on the front and back of the fixed frame 14, and the power output ends of the two brake motors 13 are fixedly connected to the front and back of the connecting frame 15 respectively;

[0023] In this embodiment, the telescopic column 4 can extend and retract along with the movement of the support plate 2, thereby improving the stability of the support plate 2 when it moves up or down. At the same time, the connecting frame 15 rotates inside the fixed frame 14, and the rotation of the connecting frame 15 can drive the tester 3 to adjust the angle during use.

[0024] Specifically, a support platform 7 is fixedly connected to the upper surface of the base plate 1. The upper surface of the support platform 7 is fixedly connected to the bottom surface of the controller 6. In this embodiment, the controller 6 can be fixed to the base plate 1 for use through the support platform 7. At the same time, the controller 6 is a control device with editable logic, which can flexibly realize various control functions and adapt to different control objects and process changes.

[0025] Specifically, each telescopic column 4 is fixedly connected to a fixing plate 5 at its bottom end, and the bottom surface of each fixing plate 5 is fixedly connected to the upper surface of the base plate 1. In this embodiment, the telescopic column 4 can be fixed to the base plate 1 through the fixing plate 5, thereby making the telescopic column 4 sturdy.

[0026] Specifically, two sets of connecting posts 9 are fixedly connected to the bottom surface of the base plate 1. Each connecting post 9 has a support ring 8 fixedly connected to its bottom end. In this embodiment, the support ring 8 can be fixed to the base plate 1 through the connecting posts 9, and the support ring 8 can be used to make the base plate 1 stable for use.

[0027] Specifically, a reinforcing ring 12 is fixedly connected to the outer surface of the telescopic end of the electric push rod 11. The upper surface of the reinforcing ring 12 is fixedly connected to the bottom surface of the support plate 2. In this embodiment, the connection between the electric push rod 11 and the support plate 2 can be reinforced by the reinforcing ring 12, and the stability of the electric push rod 11 driving the support plate 2 to move can be improved.

[0028] Specifically, each brake motor 13 has a fixed base 17 fixedly connected to its bottom surface. The two fixed bases 17 are fixedly connected to the front and back sides of the support plate 2 respectively on their side faces. In this embodiment, the brake motor 13 can be fixed to the support plate 2 through the fixed base 17, so that the brake motor 13 can rotate stably.

[0029] Specifically, a protective shell 10 is fixedly connected to the outer surface of each fixed base 17. Each protective shell 10 is fitted over the outside of the brake motor 13. In this embodiment, the brake motor 13 can be protected inside by the protective shell 10, and the opening of the protective shell 10 can be used to dissipate heat from the brake motor 13, which can further improve the service life of the brake motor 13.

[0030] Specifically, two limiting rings 16 are fixedly connected to the outer surface of the connecting frame 15. The two limiting rings 16 are close to each other on one side and respectively contact the front and back of the fixed frame 14. In this embodiment, the limiting rings 16 can limit the connecting frame 15 to the fixed frame 14, so that the connecting frame 15 can rotate stably.

[0031] The working principle and usage process of this utility model are as follows: In use, firstly, connect the brake motor 13, electric push rod 11, tester 3, and controller 6 to the power supply. Simultaneously, connect the brake motor 13 and electric push rod 11 to the controller 6. Using the connecting column 9 and support ring 8, place the base plate 1 in a suitable position. When the angle of the tester 3 needs adjustment, the controller 6 starts the brake motor 13 to rotate forward or backward. Simultaneously, the rotation of the brake motor 13 drives the connecting frame 15 to rotate within the fixed frame 14. The forward or reverse rotation of the connecting frame 15 then drives the tester 3 to adjust its angle, thereby adjusting the tester 3 to the appropriate position. Once the angle adjustment of the tester 3 is complete... When the height of the tester 3 needs to be adjusted, the electric push rod 11 is extended and retracted again via the controller 6. Simultaneously, the extension and retraction of the electric push rod 11 causes the support plate 2 to move up or down. The movement of the support plate 2, in turn, causes the telescopic column 4 to extend and retract. The extension and retraction of the telescopic column 4 ensures the stability of the support plate 2's movement. When the support plate 2 moves up or down, it causes the fixing frame 14, connecting frame 15, fixing base 17, and brake motor 13 to move up or down. The movement of the connecting frame 15 then adjusts the height of the tester 3 to a suitable position, allowing for adjustment during use and further improving the convenience of testing high-voltage wire harness shielding.
