Description

Technical Field

[0001] The utility model relates to the technical field of cable detection, in particular to a cable withstand voltage test tool. Background Art

[0002] Wires and cables are wire products used to transmit electrical energy, information and realize electromagnetic energy conversion. With the advancement of technology and the increase in application needs, the types and application scope of cables are constantly expanding. The cable withstand voltage test tool is a special device for conducting cable withstand voltage tests. It is mainly used to test the insulation strength and withstand voltage of cables at a specific voltage to ensure that the cables can be used safely under normal operating conditions. When conducting a cable withstand voltage test, the tool will apply a voltage higher than normal operation to the cable for a period of time. If the insulation performance of the cable is good enough, the voltage applied to it will only produce a small leakage current. By observing and measuring the size of the leakage current, it can be determined whether the insulation performance of the cable is qualified.

[0003] During the use of existing cable withstand voltage test equipment, workers are usually required to hold one end of the cable into the tester for testing. During the test, the tester will apply a voltage higher than normal operation to the cable for a period of time to observe the insulation performance of the cable. During this process, workers may suffer electric shock, which greatly increases the risk of endangering workers' safety. During the test, it is inconvenient to clamp and fix the cable, which may cause the cable to shake and cause the cable to deviate inside the tester, making it impossible to effectively test the withstand voltage performance of the cable, thereby reducing the accuracy of the test results.

By setting the guiding mechanism 2, the device The cable is conveyed forward, which reduces the safety risk of operators during the cable withstand voltage test. By setting the guide wheel 253, it is convenient to guide the cable through its outer curvature while conveying the cable forward, and guide the cable into the tester 4 through the guide groove 34. By setting the guide rod 254 and the spring 255, it is convenient to adjust the guiding of cables of different diameters through the elasticity of the spring 255 itself, and the guide rod 254 can guide when the spring 255 is compressed and rebounded, which improves the convenience of using the device. By setting the slider 256 and the slide groove 257, it is convenient for the guide wheel 253 to slide up and down along the slide groove 257 during adjustment, which improves the stability when guiding cables of different specifications.

[0023] refer to Figure 1 , Figure 2 and Figure 4As shown, the second driving member 32 includes a bearing seat 321 fixed to one side of the clamping platform 31, and a motor 322 arranged on one side of the bearing seat 321. The second driving member 32 also includes a forward and reverse screw rod 323 arranged at the output end of the motor 322, and a moving block 324 threadedly connected to the outside of the forward and reverse screw rod 323; the adjusting member 33 includes a first rotating rod 331 rotating on the outside of the moving block 324, and a second rotating rod 332 rotating on the outside of the first rotating rod 331; the adjusting member 33 also includes a connecting seat 333 arranged at one end of the first rotating rod 331 and the second rotating rod 332, and a clamping plate 334 fixed to the bottom of the connecting seat 333; by arranging the motor 322 and the forward and reverse screw rod 323, it is convenient to drive the moving block 324 to move, and the moving blocks arranged at both ends of the forward and reverse screw rods 323 When 324 moves, it moves in opposite directions. By setting the moving block 324, it is convenient to drive the first rotating rod 331 and the second rotating rod 332 to rotate when moving. By setting the first rotating rod 331 and the second rotating rod 332, when the moving blocks 324 at both ends of the forward and reverse screws 323 move toward the middle, the first rotating rod 331 and the second rotating rod 332 connected to the outer side of the moving block 324 are rotated to follow the movement. As the first rotating rod 331 and the second rotating rod 332 move toward the middle, the rotation angles of the first rotating rod 331 and the second rotating rod 332 are close to right angles, and the clamping plate 334 is driven downward by the connecting seat 333. While the clamping plate 334 moves downward, its two sides slide along the outer side of the bearing seat 321 to clamp the cable, thereby ensuring that one end of the cable will not be displaced when tested inside the tester 4, thereby improving the stability of the cable test.

[0024] Working principle: When in use, first put one end of the cable between the conveyor belt 24 and the guide wheel 253 for limiting. After the cable enters the outer side of the guide wheel 253, the spring 255 above it is compressed upward according to the diameter specification of the cable. The rebound force generated by the spring 255 makes the cable tightly fit the surface of the conveyor belt 24. Then the first driving member 22 is started to drive the rotating roller 23 to rotate, driving the conveyor belt 24 to rotate in a circle. The cable then moves to the guide groove 34 with the conveyor belt 24 under the limit of the guide wheel 253. Then, one end of the cable enters the interior of the tester 4 through the guide groove 34. Before the test starts, the motor 322 drives the forward and reverse screws 32 3 is rotated, and the moving block 324 connected to the outer side of the forward and reverse screw rods 323 with threads moves toward the middle, and the first rotating rod 331 and the second rotating rod 332 connected to the outer side of the moving block 324 follow the movement. As the first rotating rod 331 and the second rotating rod 332 move toward the middle, the rotation angle is close to a right angle, and the clamping plate 334 is driven to move downward through the connecting seat 333. While the clamping plate 334 moves downward, its two sides slide along the outer side of the bearing seat 321 to clamp the cable, ensuring that one end of the cable will not be displaced when the tester 4 is tested, thereby improving the stability of the cable test. Then, the operation command is input through the control panel 5 to start the test.
