Description

Technical Field

[0001] The utility model relates to the technical field of cable brackets, in particular to a cable bracket for wiring in building engineering. Background Art

[0002] In modern building engineering, cable brackets, as the basic support structure for laying electric wires and cables, are of self-evident importance. However, there are a series of problems in the design and application of existing cable brackets. Especially when the cable passes through, it causes damage to the outer surface of the cable. This defect not only affects the electrical performance and service life of the cable, but also hides potential safety hazards, becoming a key technical challenge that the industry urgently needs to solve.

[0003] When designing existing cable brackets, the smoothness and roundness of the contact surface with the cable are often ignored. When the cable passes through the bracket, sharp edges or uneven surfaces will scratch the cable outer skin, resulting in wear of the insulation layer and even scratching of the conductor, thus affecting the electrical performance of the cable. The damage to the insulation layer will reduce the insulation resistance of the cable, increase the risk of electric leakage, and may even lead to short-circuit accidents in severe cases, threatening the stable operation of the electrical system and personal safety.

[0004] The damage to the outer surface of the cable accelerates the aging process of the cable. The damage to the insulation layer weakens the cable's ability to resist external environmental factors, such as moisture, corrosive gases, and ultraviolet radiation. These factors will accelerate the deterioration of the insulation material and shorten the service life of the cable. In addition, the damaged part may become an entrance for microorganisms or chemical erosion, further aggravating the damage degree of the cable, increasing the frequency of maintenance and replacement, and raising the operation cost of the engineering project.

[0005] The defects in the design of existing cable brackets also affect the construction efficiency and operation safety. During the wiring process, the friction between the cable and the bracket not only increases the tensile force requirement and prolongs the construction time, but also may cause the cable to break or personnel to be injured due to improper operation. In addition, the damage to the cable surface increases the difficulty of inspection and maintenance for construction workers, reduces the safety and convenience of operation, and affects the overall construction progress.

[0006] Therefore, how to provide a cable bracket for wiring in building engineering is an urgent problem for those skilled in the art to solve. Content of the Utility Model

[0025] In modern construction projects, cable brackets, as the basic support structure for laying electrical wires and cables, are of self-evident importance. However, there are problems in the design and application of existing cable brackets. Especially at the moment when the cable passes through, it causes damage to the outer surface of the cable. This defect not only affects the electrical performance and service life of the cable, but also hides potential safety hazards, becoming a key technical challenge that the industry urgently needs to solve.

[0026] When designing existing cable brackets, the smoothness and roundness of the contact surface with the cable are often overlooked. When the cable passes through the bracket, sharp edges or uneven surfaces will scratch the cable outer skin, resulting in wear of the insulation layer and even scratching of the conductor, thus affecting the electrical performance of the cable. The damage to the insulation layer will reduce the insulation resistance of the cable, increase the risk of electric leakage, and may even cause short-circuit accidents in severe cases, threatening the stable operation of the electrical system and personal safety.
