Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable testing technology, specifically to a cable testing wiring device. Background Technology
[0002] Cable inspection is a crucial means of ensuring the safe and stable operation of cables. It utilizes various technologies and equipment to test various performance characteristics of cables, including insulation resistance, DC resistance, withstand voltage, and partial discharge. Insulation resistance testing determines the quality of the cable insulation layer; DC resistance testing reveals the conductivity of the cable conductor; withstand voltage testing verifies the insulation strength of the cable under a specified voltage; and partial discharge testing detects internal insulation defects. Cable inspection helps to promptly identify potential cable problems, allowing for early repair or replacement measures to prevent power outages caused by cable faults and ensuring the reliable operation of power systems and related equipment.
[0003] Currently, cable fault testers are commonly used to inspect cables. When using a cable fault tester, the transmitter of the tester is usually connected directly to one end of the faulty cable via a dedicated test lead. Currently, when connecting the test lead to the cable, clamps are usually used to hold the connection. However, because cables vary in size, some larger diameter cables, although the clamps can be held onto the cable when fully extended, are not held securely, affecting the testing results and hindering the staff from detecting cable faults.

[0026] Furthermore, the connecting mechanism also includes a U-shaped plate 9 and three connecting plates 10. The U-shaped plate 9 is fixedly connected to the upper part of the outer surface of the extension plate 5. The mounting plate 3 is slidably inserted into the inner wall of the U-shaped plate 9. The three connecting plates 10 are respectively fixedly connected to the lower ends of the front, left and right surfaces of the mounting plate 3. The lower surface of the U-shaped plate 9 is threaded with connecting bolts 11 corresponding to the positions of the three connecting plates 10. The upper ends of the three connecting bolts 11 are threaded through the interior of the three connecting plates 10.
[0027] Furthermore, by installing or removing the extension plate 5, the connection mechanism can flexibly adapt to the wiring requirements of cables with normal and larger diameters, improving the versatility and applicability of the device. The setting of the limit plate 13, spring 14 and L-shaped rod 15 can prevent the clamping plate 6 from moving excessively when the mounting plate 3 is used alone, further enhancing the practicality and safety of the connection mechanism, facilitating the detection of cable faults by staff, and improving the work efficiency of staff.

At this time, the larger diameter cable terminal can be placed between the terminal plate 1 and the clamping plate 6. Turn the handle 8 again until the clamping plate 6 clamps the cable to complete the wiring operation.
