Cable plug

Abstract

The invention relates to a cable plug which is made of a full ceramic or full glass material, formed by combining equal parts of 1 / 2 or 1 / 3 single bodies into a whole, and shaped as a conical sleeve with a T head, wherein the outer diameter R1 of the conical sleeve is slightly smaller than the inner diameter of a protective tube; the inner diameter R2 of the conical sleeve is slightly greater than the diameter of the cable; the outer diameter R3 of the T head is slightly greater than the outer diameter of the protective tube; and a cone angle b is 5-15 degrees. The cable plug can be used for performing fire prevention, preventing fire from spreading after firing, preventing small animals from burrowing into the protective tube to further bite the insulating layer of the cable, and preventing rain erosion and preventing the fixed cable from shaking in the protective tube, a wall body and equipment. The cable plug can be widely applied to parts which are needed to be protected by the protective tube or neccessarily penetrates through the wall body and neccessarily enters into equipment such as a high-voltage switch cabinet, a low-voltage switch cabinet and a control cabinet so as to be plugged in the fields of electric power, communication, televisions and broadcasting.

Description

technical field [0001] The invention relates to a cable blocking piece, which is applied to high-voltage cables, low-voltage cables, control cables, communication cables, optical cables, etc. in the fields of electric power, communication, television, and broadcasting, etc., which need to be protected by protective tubes or have to pass through walls, floors, floors and It must enter the high and low voltage switch cabinets, control cabinets, metering boxes, various meter boxes, cabinets and other equipment that need to be sealed. Background technique [0002] In the prior art, when cables pass through the entrance or exit of the protective pipe, when the cables pass through the wall to lead into or out of the cable room, or when the cables enter the entrance of the equipment, organic blocking materials such as fireproof mud are used for sealing, but most cables pass through the protective pipe. Tubes or access equipment are not blocked. There are many deficiencies in organ...

AI Technical Summary

Problems solved by technology

First, the organic blocking material is a kind of chemical product, soft, and the production cost is high, about 20,000 yuan per ton, and there is certain pollution and odor during production

Second, the organic blockage is highly viscous, and it is easy to stick to hands, equipment, and workplaces during use, making it difficult to clean.

Third, in the maintenance process of cables or equipment, when removing organic blocking materials, it is very difficult in terms of workload, work difficulty and environmental sanitation.

Fourth, when plugging, the organic blocking material is inconvenient in shape and shape, and it is easy to deform, change color and turn black when the temperature is high. After repairing cables and equipment, it is difficult to restore the plugging to its original state, so it can only be piled up at will

At present, there are no simple, efficient and environmentally friendly sealing measures for the sealing of cable protection tubes, cables passing through walls or entering equipment in China, except for some organic blocking materials.
