Electrical wire wall-passing device

Abstract

The invention relates to a wall passing device for wire, which comprises a wall passing leading sleeve, wire passing plugs, a pressing cap and a spring retaining ring. The wall passing leading sleeve is a hollow screw bolt having a bolt head, a polished section, and a screw section; the diameter and length of the polished section matches the shell wall hole; the screw section has a matched nut for fixing the hollow screw bolt in the shell wall hole. A sealing member is disposed between the matching surfaces of the wall passing leading sleeve and the shell wall; the wall passing leading sleevehas a plurality of small inner holes arranged dispersively, in each small inner hole, a wire passing plug is disposed in which a wire passes through; the wire passing plug is in conical tube structure, and the outer surface is a cone; the pressing cap is a perforated plate, in which, the number and position of the holes is relative to the small holes on the wall passing leading sleeve, and the diameter of the holes is smaller than that of the big end of the wire passing plug; the spring retaining ring is disposed between the nut and the pressing cap, where the pressing cap presses the big endsurface of the wire passing plug to compress the wire passing plug in the small hole of the wall passing leading sleeve. The invention achieves the advantages that: effective seal is arranged betweenthe wire passing device and the shell wall, between the different wires, thereby, the anti-seepage reliability is high, wire passing is convenient, the structure is simple, and the mounting and demounting are easy.

Description

technical field [0001] The invention relates to a wire wall piercer, which is used for passing the wires of electrical equipment in a closed device out of the shell wall of the closed device. Background technique [0002] Some closed devices, such as bearing boxes and gearboxes in large hydraulic mechanical equipment, usually have cables of electrical equipment that need to be connected, but due to the need for lubrication of bearings, gears and other components when the equipment is running, oil splashes in the entire box chamber At the same time, it will also form aerosolized tiny oil droplets that diffuse in the box chamber, making it difficult for ordinary threaders to achieve the sealing effect. Security risks. And some threaders in the form of aviation sealed plugs, although they can achieve the effect of sealing and anti-seepage, have defects such as complex structure, internal and external leads need to be broken, inconvenient wiring, difficult disassembly, high man...

Problems solved by technology

[0002] Some closed devices, such as bearing boxes and gearboxes in large hydraulic mechanical equipment, usually have cables of electrical equipment that need to be connected, but due to the need for lubrication of bearings, gears and other components when the equipment is running, oil splashes in the entire box chamber At the same time, it will also form aerosolized tiny oil droplets that diffuse in the box chamber, making it difficult for ordinary threaders to achieve the sealing effect. Security risks

And some threaders in the form of aviation sealed plugs, although they can achieve the effect of sealing and anti-seepage, have defects such as complex structure, internal and external leads need to be broken, inconvenient wiring, difficult disassembly, high manufacturing cost, and expensive price, etc., so it is difficult to be promoted. application
