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

The cable blocking piece

Technical field

The present invention relates to a kind of cable blocking piece; the high-tension cable, low-voltage cable, control cable, telecommunication cable, optical cable etc. that are applied to electric power, communication, TV, broadcast world need maybe must pass floor, the floor of body of wall and must enter equipment such as high and low pressure switch cubicle, control cubicle, batch meter, various table case, cabinet, the position that need carry out shutoff with the pillar protection.

Background technology

In the prior art, cable passes the pillar import or export and cable passes body of wall introducing or outgoing cable chamber or cable access arrangement porch, all adopt such as organic putties such as anti-chamotte and carry out shutoff, but most cable passes pillar or not shutoff of access arrangement.There are many deficiencies in organic putty shutoff.The one, organic putty is a kind of chemical products, software, and the production cost height, per ton is about 20000 yuan, and certain pollution and smell are arranged during production.The 2nd, organic putty viscosity is big, easily sticking hand in the use, and sticking equipment, sticking workplace is not easy to clean clean.The 3rd, in the maintenance process of cable or equipment, when removing organic putty, on the workload, on work difficulty and the environmental sanitation big difficulty is arranged all.The 4th, during shutoff, organic putty is inconvenient in moulding, typing, and also easy modification, variable color were turned black when temperature was high, organic putty sink naturally when running into the heavy caliber pillar, be difficult for blocking the mouth of pipe, particularly the shutoff behind recovery cable and equipment is difficult to also its original state, can only arbitrarily pile stifled.

Cable protecting tube all is seen everywhere in the streets and lanes in small towns or city, the cable of shutoff not, and majority wanders off in pillar, is difficult to see.The pillar mouth that adopts organic putty shutoff again can't moulding and typing, can only arbitrarily pile stifledly, influences overall image and allows the people cause illusion easily, is most unseemly.For this reason, cable protecting tube should adopt an effective means and carry out shutoff.Also embodying simultaneously a kind of technical ability and the sense of duty of industry, and also coordinating mutually with the society of harmonious civilization.Shutoff, the cable of cable protecting tube pass body of wall or access arrangement at home at present, except part adopts organic putty, also do not have shutoff measure succinct, high-efficiency environment friendly.

Summary of the invention

The purpose of this invention is to provide a kind of cable blocking piece, can address the problem: the one, when cable is on fire, the fire spreading of can blockading; The 2nd, prevent from that toys such as mouse, gecko, scorpion, snake, bat, small worm from piercing to sting bad cable insulation in pillar or the equipment, cause cable to open circuit, cause fire or cause the accident because of the cable damage equipment that opens circuit; The 3rd, prevent that toy from piercing bite in pillar or the equipment maintenance, maintainer; The 4th, cable is fixed in pillar, body of wall and the equipment, avoid not having rocking for a long time of attached cable, gall insulating barrier, cause cable to open circuit; The 5th, not shutoff of cable protecting tube, be subjected to rain erosion to cause pillar rust mashed throughout the year.

Be to realize goal of the invention, the technical solution used in the present invention is: the cable blocking piece, be integrated by 1/2 or 1/3 monomer of five equilibrium, and it is shaped as the taper of band T head, taper external diameter R ₁Be slightly less than the pillar internal diameter, taper internal diameter R ₂Be slightly larger than cable size, T external diameter R ₃Be slightly larger than the pillar external diameter, cone angle b is the 5-15 degree.

For the shutoff that 2 cables are arranged in the pillar, the cable blocking piece is integrated by 1/2 of five equilibrium, and taper center symmetry is also shown 2 pipelines.

For the shutoff that 4 cables are arranged in the pillar, the cable blocking piece is integrated by 1/2 of five equilibrium, and taper center symmetry is also shown 4 pipelines.

For the shutoff that 3 cables are arranged in the pillar, the cable blocking piece is integrated by 1/3 of five equilibrium, and taper center symmetry is also shown 3 pipelines.

For the shutoff of the cable that advances equipment, the cable blocking piece is integrated by 1/2 of five equilibrium, cone angle 5-10 degree.

Cable for power plate, cabinet, case enters the hole, what have is kidney shape, what have is rectangle, the material of cable blocking piece is that full pottery or full glass material are made, be integrated by 1/2 of five equilibrium, it is shaped as the taper of band T head, and the kidney shape of taper profile and power plate, cabinet, case or rectangle cable enter the hole and match, taper center symmetry is also shown 2-3 pipeline, the internal diameter R of each pipeline ₂Be slightly larger than cable size, the cone angle of taper is the 5-10 degree.

Cable blocking piece easy health when installing and using that the present invention proposes only needs the cable blocking piece is clamped cable, gets final product in the cable aperture of insertion pillar, equipment, body of wall.Cable, equipment safe ready when repair and maintenance does not need any skill, as long as blocking piece is detachably changed by inserting mouthful outside dialling just, organizes work.For irregular body of wall cable aperture, can carry out the production of non-regular pattern composite blocking piece according to customer requirements, make extraordinary blocking piece.Under the parallel situation of many cables, for the cable slotted section, can adopt the organic putty joint filling of part.

The alternative organic putty of cable blocking piece of the present invention need in electric power, communication, TV, the broadcast industry to be applied to cable is protected or passed at it position that occasions such as body of wall and access arrangement need be carried out shutoff with pillars such as iron pipe, galvanized pipe, rubber tube, bellows, plastic tubes.Have following effect and effect:

1, the making material of the making material of cable pottery blocking piece and glass blocking piece is not only common but also abundant, member is simple, convenient for production, the productivity effect height, cost of manufacture is low, the cost of each shutoff mouth is the 1/4-1/5 of organic putty, the scope of application is wide, and quality and benefits is much larger than organic putty, and prospect is undisputed.

2, the cable blocking piece is a kind of environment-friendly products of pollution-free, non-harmful conservation culture, meets new period power-saving technology requirement.

3, cable blocking piece finished product is solid members, and moulding is generous, firm not modification, and anti-intensity is big, high temperature resistant, insulation, ten thousand volts of anti-electric shock is withstand voltage 1-1.2.

4, the cable blocking piece can use repeatedly as long as under not damaged, indehiscent situation, has saved resource greatly and has saved production cost.
