Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinets, in particular to a power distribution cabinet based on a cable fixing and adjusting structure. Background Art

[0002] The main function of the distribution cabinet is to open and close, control and protect electrical equipment in the process of power generation, transmission, distribution and energy conversion in the power system. The distribution cabinet is mainly suitable for power plants, substations, petrochemicals, metallurgy and steel rolling, light industry and textiles, factories and mines, and residential areas.

[0003] Although the existing design of the distribution cabinet can also connect cables, when in use, the cables are easily pulled by external force, causing the cable interface to become loose, which in turn causes the distribution cabinet to have poor contact when in use, affecting the use of the distribution cabinet. In addition, the existing design of the distribution cabinet is generally stored in a cool place, which causes the air humidity in the distribution cabinet to be high, which can easily cause corrosion and damage to the electronic components in the distribution cabinet for a long time, reducing the service life of the distribution cabinet. Therefore, a distribution cabinet based on a cable fixing and adjustment structure is proposed.

[0004] The existing patent (publication number: CN207819185U) discloses a power distribution cabinet based on a cable fixing and adjustment structure, including a power distribution cabinet body and a baffle with a cable inlet, the baffle having a first cable through hole, a cable clamping member on the cable inlet, the cable clamping member including a fixed sleeve connected to the baffle and a fixed adjustment structure; the fixed adjustment structure includes a sliding portion and a fixed portion connected above the sliding portion, the center of the fixed adjustment structure has a second cable through hole; the periphery of the fixed portion has a reduced diameter groove; the sliding portion is arranged in the fixed sleeve, the side of the fixed sleeve has an opening, the side of the sliding portion is connected to a slider, and the slider passes through the opening; the fixed sleeve has a first positioning hole, the sliding portion has a second positioning hole that matches the first positioning hole, and positioning pins are inserted into the first positioning hole and the second positioning hole. This power distribution cabinet based on a cable fixing and adjustment structure has the advantage of firmly clamping cables. In the process of realizing the utility model, the inventors found that the prior art had the following problems: 1. The existing design of the distribution cabinet is not perfect in terms of cable fixation. The cables are easily pulled by external forces, which may cause the cable interfaces to loosen, resulting in poor contact of the distribution cabinet when in use; 2. The existing design of the distribution cabinet is not perfect in terms of moisture resistance. The distribution cabinet is stored in a cool place for a long time, and the air humidity is high, which may easily cause corrosion and damage to the electronic components in the distribution cabinet.
