Description

Technical Field

[0001] The utility model belongs to the technical field of electric power systems, and in particular relates to a wiring protection component for high and low voltage electrical equipment. Background Art

[0002] One of the most common equipment and facilities in the power system is the protective equipment used for safety, and the most important of the protective equipment is the wiring protection device. The wiring protection device can be used to protect the wiring terminals of high-voltage or low-voltage electrical equipment to prevent them from being exposed. The existing wiring protection device has a box-type shell structure with transparent ends at both ends. The two ends of the two wirings of the electrical equipment are respectively placed in the through grooves of the shell, and then the wiring is squeezed by the abutment mechanism to ensure the stability of the wiring.

[0003] A Chinese patent application (or patent) with the announcement number CN220291088U discloses a novel wiring protection device for electric power engineering, including a bottom shell, a top cover / pressing plate, a No. 1 nut and a threaded rod, one side of the bottom shell is fixedly connected with two symmetrically arranged flip blocks, the inside of the two flip blocks is provided with a flip groove, the side of the top cover close to the flip block is fixedly connected with two symmetrically arranged connecting blocks, the bottom surfaces of the two connecting blocks are fixedly connected with L-shaped rods, the outer walls of the two L-shaped rods are respectively slidably connected with the two flip grooves, and the adjacent sides of the two flip blocks are connected with a limiting assembly. This novel wiring protection device for electric power engineering can separate the top cover and the bottom shell without disassembly through the connection of the L-shaped rod and the flip block, and then through the action of the flip groove, and the separation will not affect the placement of wires inside the bottom shell, and finally the bottom shell and the top cover are squeezed by the limiting assembly, which increases stability and is convenient and easy to operate.

[0004] The above-mentioned new wiring protection device for power engineering has through-slot structures on both sides of the shell, which are used for the insertion of wires at both ends. The outer diameters of different types of wires are also different, and there is no shielding structure on the notches on both sides of the shell. Therefore, when the wires are inserted into it, shaking will occur, and the problem of exposed terminal will also occur; and a screw is inserted into the top of the shell, a No. 1 nut is provided in the middle of the screw, and a pad and a pressure plate are provided at the top and bottom of the screw respectively, but the nut and the screw are both metal parts, and the bottom of the screw is directly in contact with the exposed terminal of the wire head through the pressure plate. The current on the wire will be transferred to the screw through the pressure plate, making the entire screw charged, and the pad used for hand-holding at the top shaft end is not only thin and small, which is not conducive to hand-holding, but also touches the screw when held, which poses a problem of operational danger. To this end, we provide a wiring protection component for high and low voltage electrical equipment to solve the above-mentioned problems. Utility Model Content
