A new type of cable penetration sealing device

Abstract

The invention relates to a novel cable penetrating sealing device which comprises a back plate, a bottom plate, a pressing plate and wire passing modules. Symmetrical bent portions are integrally arranged on the two sides of the back plate and extend to the same side of the back plate, and the pressing plate is embedded in the upper portion between the inner side surfaces of the bent portions, and the bottom plate is embedded in the lower portion between the inner side surfaces of the bent portions. A plurality of layers of wire passing modules are embedded between the pressing plate and the bottom plate. At least one through hole is formed in each layer of wire passing module, the through holes correspond to holes formed in the back plate, and an annular rubber ring is embedded in each through hole. According to the novel cable penetrating sealing device, a plurality of cables are arranged in each wire passing module in a penetrating mode, and each cable is connected with a protruding ring arranged in the middle of the inner edge of each rubber ring in a pressing mode. Due to elasticity of rubber, the cables are tightly wrapped, and the purposes of preventing wind, preventing dust, preventing corrosion and preventing mouse biting are achieved. Moreover, the modules are shifted integrally, installation is simple and convenient and flexible, regulation is convenient, and floor area is small.

Description

technical field [0001] The invention belongs to the technical field of cable penetration sealing, in particular to a novel cable penetration sealing device. Background technique [0002] Electrical switch cabinets, distribution boxes, inverter cabinets and other equipment are common equipment in industrial production. They integrate various switches, meters, inverters and other equipment that must be used in production to facilitate management and use. These electrical appliances Switch cabinets, distribution boxes, inverter cabinets, etc. should be protected from wind, dust, corrosion, and rodents when they are in use. At the same time, a large number of cables should be used to connect with other equipment. When these cables pass through the cabinet or box, there will be gaps between the outer edge of the cable and the cabinet or box. These gaps will easily allow dust, mice, corrosion, etc. to enter the cabinet or box, seriously affecting the safety of the equipment. Ther...

Problems solved by technology

When these cables pass through the cabinet or box, there will be gaps between the outer edge of the cable and the cabinet or box. These gaps will easily allow dust, mice, corrosion, etc. to enter the cabinet or box, seriously affecting the safety of the equipment. Therefore, through research, people put a rubber ring on the inner edge of the hole made by the cabinet or box body, and the inner edge of the rubber ring is crimped on the outer edge of the cable worn inside it. This structure does play a certain role. However, when there are many cables, the floor area is large, the design of the cabinet or box is not good, and the installation of cables is also extremely inconvenient.
