[0002] Low-voltage switchgear and control equipment, commonly known as low-voltage switch cabinets or low-voltage distribution cabinets, refers to complete electrical installations with AC and DC voltages below 1000V. Low-voltage distribution cabinets require cable connections to external equipment, thus necessitating incoming and outgoing line connections.

[0003] According to the patent application CN219436481U, "This utility model discloses a low-voltage distribution cabinet for protecting circuits, including a cabinet body. A housing is fixedly connected to the right side of the bottom of the cabinet body's inner cavity. Shells are fixedly connected to both sides of the top of the inner cavity of the housing. An electric push rod is fixedly connected to one side of the bottom of the shell, and a sliding plate is fixedly connected to the top of the electric push rod. This utility model, by adding a limiting structure, facilitates the organization and limiting of circuits, preventing messy circuits from causing trouble for maintenance personnel and improving work efficiency. By adding a heat dissipation structure, it facilitates heat dissipation and dust removal from the circuits, preventing damage to the circuits caused by high temperatures generated by high voltage. It also prevents the circuits from aging due to prolonged exposure to dust, thereby increasing the service life of the circuits. This not only solves the problems for maintenance personnel but also meets their needs. This structure is simple to operate and easy to maintain in the future."

[0040] After the cable enters the low-voltage distribution cabinet 1, by pulling the handle 58 outward, the handle 58 causes the locking block 56 to slide outward, separating the locking block 56 from the locking groove of the cover plate 52. Then, the cover plate 52 is removed, and the cable is passed through the branch channel 51 and led out from the branch hole 53 of the cover plate 52. Then, the cover plate 52 is aligned with the branch channel 51 and pressed into the front of the branch channel 51. The elastic force of the first spring 427 causes the locking block 56 to be pressed, so that the locking block 56 is inserted into the locking groove of the cover plate 52, thereby fixing the cover plate 52.
