Description

Technical Field

[0001] The utility model relates to the field of wire harnesses, in particular to a wire harness that is easy to adjust and is used in weak current engineering. Background Art

[0002] A wire harness rack is a cable support system commonly used in weak current engineering projects to support and install cables or other signal transmission equipment. In the existing technology, a wire harness rack often fixes or clamps the passing cables horizontally, and the clamping direction is difficult to adjust. The cables are not parallel to the clamping grooves, resulting in bending, thereby increasing the probability of cable wear and signal attenuation.

[0003] According to the patent CN220797688U, an adjustable cable tie rack for weak current engineering is provided with a rotatable clamping frame inside the cable tie rack. The clamping frame can rotate itself through the rotating shafts on both sides. When the cable extends from a high point or a low point to the cable tie rack, the clamping frame can be adjusted according to the actual angle of the cable to ensure that the cable will not bend due to being not parallel to the clamping groove when it is fixed through the clamping groove, thereby reducing the probability of cable wear and signal attenuation.

[0004] During the development of this utility model, the inventors discovered that the prior art had at least the following unresolved issues: The aforementioned embodiment adjusts the angles of each set of clamping grooves on the surface of the clamping frame by rotating the clamping frame. However, the adjustment angles of each set of clamping grooves are the same, while the angles of each cable on the same horizontal plane are not always the same, resulting in a limited range of use. Therefore, a new technical solution is needed to address this issue. Utility Model Content
