Description

Technical Field

[0001] This utility model relates to the field of high-voltage power testing technology, specifically a cable clamp for high-voltage power testing. Background Technology

[0002] Common cable ties are generally only used to bundle small-diameter wires. However, for several cables with larger diameters, appropriate cable clamps are needed for bundling and fixing. Existing cable clamps mostly use ordinary clamps, which are generally made of strip metal sheets with screw holes at both ends. These clamps are used to limit the diameter of the cable clamp and cannot be adjusted according to the different diameters of the cables. This means that when installing cables of different diameters, different diameter cable clamps are needed to fix the cables. Moreover, cable clamps are generally used to clamp and fix a single cable.

[0003] Publication No. CN221124635U discloses a cable clamp for high-voltage power testing. A handle drives a lead screw to rotate, controlling a pressure plate to approach a turntable. The cable passes through a through hole in the turntable's surface block, and the pressure of the pressure plate achieves rapid fixing. Several extrusion grooves are set on one side of the turntable; clockwise rotation causes a keyway on the outer side of the turntable to engage with a key on the inner wall of a fixing plate, achieving a limit adjustment effect. This can improve equipment utilization and reduce production costs. However, this patent still has the following problems in actual use: Although this cable clamp for high-voltage power testing uses a handle to drive a screw to rotate, controlling the pressure plate to approach the turntable, and the cable passes through the through hole in the surface block of the turntable, achieving rapid fixation by using the pressure of the pressure plate, it is not convenient to clamp and fix cables of different sizes during high-voltage power testing. In addition, it can only clamp one cable at a time, thus affecting the efficiency of cable clamping and testing.

[0004] Therefore, a cable clamp for high-voltage power testing is proposed to solve the problems mentioned above. Utility Model Content
