Description

Technical Field

[0001] This application relates to the field of cable testing technology, and in particular to a cable testing device. Background Technology

[0002] A cable is an electrical or signal transmission device, typically composed of several or groups of conductors (at least two conductors per group) twisted together in a rope-like manner. Each group of conductors is insulated from each other and is often twisted around a central core, with the entire cable covered by a highly insulating outer layer. Cables are characterized by internal conductivity and external insulation. The tightness of the cable cores is crucial for ensuring the cable's performance and reliability, directly affecting its electrical properties, including resistance, capacitance, and inductance. Poor tightness can lead to increased contact resistance, affecting current transmission efficiency, increasing energy consumption, and even causing overheating and safety hazards. In many industry standards and specifications, cable tightness is one of the important indicators for assessing its safety and compliance.

[0003] A patent with publication number CN207317670U discloses a cable filling tightness measuring device. This device involves placing the cable in a clamping groove and manually rotating a rotating rod to press a clamping plate against the cable core. The cable filling tightness is then measured by observing the position of the clamping plate relative to the scale lines before and after clamping. However, this device requires manual rotation of the clamping plate to measure the cable core tightness, which is quite laborious. Utility Model Content

[0004] The purpose of this application is to address the aforementioned problems existing in the prior art by proposing a cable testing device.

[0005] This application can be achieved through the following technical solution: a cable testing device, including a test bench for placing a cable, the cable being clamped by a clamping assembly, a driving device mounted on the test bench, the driving device having a telescopic end, a through-hole being provided through the test bench, the driving device being able to apply force to the end face of the cable so that the cable core passes through the through-hole, a pressure sensor mounted on the driving device, the pressure sensor being used to detect the pressure of the driving device on the cable, and the pressure sensor being electrically connected to a pressure gauge.

[0006] In the above technical solution, the cable is placed on the test bench, the position of the cable core relative to the outlet is adjusted, and then the clamping device is used to clamp the axial outer wall of the cable. The driving device can apply force to the cable cross section so that the core is inserted into the outlet. The pressure sensor can detect the magnitude of the force applied to the cable by the driving device, and the pressure gauge can read the pressure value in real time and record the maximum pressure value.

[0007] Furthermore, it also includes an upper ejector die, wherein the pressure sensor is mounted on the telescopic end, and the upper ejector die is mounted on the detection end of the pressure sensor.

[0008] In the above technical solution, when the driving device applies force to the cable, the cross-section of the cable may not be flat enough. Setting an upper ejector mold can prevent the cross-section of the cable from directly contacting the detection end of the pressure sensor, thus avoiding damage to the detection end of the pressure sensor caused by the cross-section of the cable.

[0009] Furthermore, the clamping assembly includes several clamping plates capable of contacting the cable and several screws threadedly connected to the test bench. The ends of the screws are rotatably connected to the clamping plates, and a handwheel is fixedly installed on the ends of the screws away from the clamping plates.

[0010] In the above technical solution, rotating the handwheel causes the screw to drive the clamping plate to slide horizontally, so that several clamping plates can clamp or release the cable.

[0011] Furthermore, the clamping plate is formed with an arc surface, which can conform to the axial outer wall of the cable at all points.

[0012] In the above technical solution, the curved surface can fit against the axial outer wall of the cable, and the clamping plate has a better clamping effect on the cable.

[0013] Furthermore, a camera is provided on the side of the outlet away from the drive device, and the camera is electrically connected to a display. The camera is used to capture images at the outlet.

[0014] In the above technical solution, after the worker places the cable on the test bench, he needs to squat down and observe the wire core from below the outlet to adjust the position of the cable core relative to the outlet, which is inconvenient. The monitor can display the image of the outlet captured by the camera, which makes it easier for the worker to adjust the position of the cable.

[0015] Furthermore, a rotating rod is rotatably mounted on the test bench, and a support basket is fixedly mounted on the rotating rod. The support basket is used to support the wire core, and the rotating rod can rotate so that the support basket is located or away from the outlet.

[0016] In the above technical solution, when a camera is needed, the rotating rod can be rotated to prevent the support basket from blocking the camera's shooting. After the cable position is adjusted, the rotating rod can be rotated in the opposite direction so that the support basket can receive the wire core pushed out from the outlet.

[0017] Furthermore, it also includes a protective ring, which is arranged around the camera, and the projection of the protective ring on the vertical plane can cover the projection of the camera on the same vertical plane.

[0018] In the above technical solution, the protective ring protects the camera and reduces the possibility of damage caused by someone kicking the camera.

[0019] Furthermore, several extension plates are installed on the protective ring, and the extension plates are fixed to the test bench by screws.

[0020] In the above technical solution, the extension plate is first fixed on the protective ring, and then the extension plate is fixed on the test bench with screws. The position of the protective ring can be fixed relative to the position of the test bench, which is more convenient.

[0021] In summary, this application has the following technical effects: the cable is placed on the test bench, the position of the cable core relative to the outlet is adjusted, and then the clamping device is used to clamp the axial outer wall of the cable. The driving device can apply force to the cable cross section so that the core is inserted into the outlet. The pressure sensor can detect the magnitude of the force applied to the cable by the driving device, and the pressure gauge can read the pressure value in real time and record the maximum pressure value.

[0025] Please refer to the attached diagram in the instruction manual. Figure 1One embodiment of this application provides a cable testing device, including a test bench 1. A drive device 3 is installed on the test bench 1. Exemplarily, the drive device 3 can be a cylinder, hydraulic cylinder, or other actuator capable of telescopic movement. The drive device 3 has an output end that can extend and retract vertically. The test bench 1 is used to place cables. Workers cut a section of the cable to be tested for tightness and place it on the test bench 1, ensuring the cable's axis is perpendicular to the ground. A pressure sensor 4 is installed on the output end of the drive device 3. The fixed end of the pressure sensor 4 is installed on the output end of the drive device 3. The detection end of the pressure sensor 4 is detachably equipped with an upper ejector mold 6, which can contact the cable core. The drive device 3 can apply an axial force to the cable core through the upper ejector mold 6. A through hole is formed in the test bench 1, allowing the upper ejector mold 6 to eject the core through the through hole 11. The pressure sensor 4 is electrically connected to a pressure gauge 5. The pressure gauge 5 is a recording type pressure gauge with a peak value recording function, capable of reading the pressure value in real time and recording the maximum pressure value.

[0026] Please refer to the attached diagram in the instruction manual. Figure 1 The cable located on the test bench 1 is clamped by a clamping device. The clamping device includes two screws 22 that are threaded to the test bench 1. The screws 22 are horizontally arranged and have the same length direction. A clamping plate 21 is rotatably installed at the end of each screw 22. The two clamping plates 21 can contact the same cable. A handwheel 7 is detachably installed at the end of the screw 22 away from the clamping plate 21. An arc surface 211 is formed on the clamping plate 21. The arc surface 211 can fit against the axial outer wall of the cable everywhere. The lower surface of the clamping plate 21 can abut against the test bench 1. Rotating the handwheel 7 can cause the screws 22 to drive the clamping plate 21 to slide horizontally and linearly so that the clamping plate 21 can clamp the cable.

[0027] Please refer to the attached diagram in the instruction manual. Figure 1 A camera 8 is installed below the outlet 11, which can capture images of the outlet 11. A monitor 9 is installed on the test bench 1, with the screen of the monitor 9 facing upwards. The monitor 9 is electrically connected to the camera 8. After the cable is placed on the test bench 1, it is necessary to check the position of the cable core from below the insertion hole to ensure that the upper ejector 6 can push the core out of the insertion hole. It is inconvenient for workers to squat down to check the position of the cable core. The camera 8 is installed on a protective ring 13, and two extension plates 14 are installed on the protective ring 13. The extension plates 14 are installed on the test bench 1 by screws. The height of the protective ring 13 is greater than the height of the camera 8. The camera 8 is located in the inner circle of the protective ring 13. The camera 8 is used to capture images of the outlet 11. Workers can see the images captured by the camera 8 through the monitor 9 and adjust the position of the cable accordingly, which is more convenient.

[0028] Please refer to the attached diagram in the instruction manual. Figure 1 A rotating rod 10 is rotatably mounted on the support leg of the test bench 1. A support basket 12 is mounted on the rotating rod 10. The support basket 12 is set with its opening facing upward. The support basket 12 can receive the wire core pushed out by the upper ejector mold 6. When it is necessary to adjust the position of the cable core relative to the outlet 11, the support basket 12 can be manually rotated to prevent the support basket 12 from obstructing the shooting of the camera 8. When the drive device 3 moves down, the support basket 12 can be manually rotated in the opposite direction so that the support basket 12 can receive the pushed-out wire core.

[0029] The working principle of this embodiment is as follows: the cable is placed on the test bench 1, the camera 8 is turned on, the position of the cable relative to the through-hole 11 is adjusted, after the adjustment is completed, the clamping component 2 is used to clamp the cable, and then the driving device 3 is used to drive the upper ejector mold 6 to move downward to apply force to the wire core so that the wire core can be inserted into the through-hole. The pressure gauge 5 can read the pressure value in real time and record the maximum pressure value.

[0030] 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.
