Technical field
The utility model belongs to cable connector technical field, and in particular in a kind of shrinkage cable of cable termination indirectly
Head.
Background technology
As industrialization is continued to develop in recent years, the demand to power cable is increasing, is setting up the process of power network
In used, it is necessary to which two sections of cables are mutually butted, you must use transition joint to connect two sections of cables, and protect it
Demonstrate,prove normal power supply.The cold contract cable middle joint of prior art is mostly directly buried installation, waterproof sealing to transition joint and anti-
The anti-mechanical damage of burn into proposes high requirement, and existing cold contract cable middle joint waterproof construction is simple, mainly by silicon rubber
The elasticity of gum cover itself ensures the sealing between cable, and waterproof effect is poor.Existing cold contract cable middle joint can not
Solve waterproof the problem of, many cable intermediate joints often operate in tunnel, inferior moist place, it is easy to there is moisture to enter
Enter, so as to cause joint short circuit, massive losses brought to user, traditional cold contract cable middle joint due to longtime running or
Accident, it may occur however that spontaneous combustion or blast, and other cables in cable duct or cable bridge formation can be injured, loss can not be estimated
Amount.
Utility model content
The problem of the utility model exists for above-mentioned prior art makes improvement, i.e., skill to be solved in the utility model
Art problem is to provide a kind of cold contract cable middle joint good airproof performance, and fire-proof and water-proof effect is good, installs simple, improves electric power and set
Standby reliability and sustainability.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
A kind of cold contract cable middle joint, including the insulation tube at two cable connector ends is sheathed on, the insulation tube is by extroversion
External shielding layer, insulating barrier and internal shield are inside divided into, insulation tube two ends are arranged with cap respectively, by cable connecting part and absolutely
Edge pipe jointing part is constituted, and is connected respectively with cable, insulation tube, the insulation tube periphery is wound with non-flammable adhesive tape, the fire retardant glue
Band periphery is arranged with connecting tube, and the connecting tube two ends are connected with the insulation pipe jointing part of cap respectively, the cable of the cap
Connecting portion is provided with interior annular groove, the interior annular groove with connecting tube two ends and is provided with water-swellable cushion rubber.
In the present embodiment, the cap is made with connecting tube by silastic material, and its outer surface is additionally provided with hydrophobic layer.
In the present embodiment, the insulative pipe sleeve is on support tube, and the support tube external diameter is not less than insulation bore,
The support tube is that zigzag shape support bar is wound hollow cylinder.
Compared with prior art, the utility model has the advantages that：The new cold contract cable middle joint ensures
Sealing property and the class of insulation at cable connector, while fire-proof and water-proof effect is good, operation installs simple, improves power equipment
Reliability and sustainability.

Embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
As shown in figure 1, a kind of cold contract cable middle joint, including the insulation tube at two cable connector ends is sheathed on, it is described exhausted
Edge pipe ecto-entad is divided into external shielding layer 6, insulating barrier 7 and internal shield 8, and insulation tube two ends are arranged with cap 2 respectively, by
Cable connecting part and insulation pipe jointing part composition, are connected, the insulation tube periphery is wound with fire retardant glue with cable, insulation tube respectively
Band 3, the periphery of non-flammable adhesive tape 3 is arranged with connecting tube 4, and the two ends of connecting tube 4 connect with the insulation pipe jointing part of cap 2 respectively
Connect, the cable connecting part of the cap 2 is provided with interior annular groove, the interior annular groove with the two ends of connecting tube 4 is provided with water-swellable
Cushion rubber 5；Install simple using this cladding attachment structure, make insulation tube uniform force, it is to avoid insulation tube deformation occur and produce gas
Gap is so as to which creepage phenomenon occur be that insulation tube punctures, while being set in insulation pipe jointing part and the two ends of connecting tube 4 of the cap 2
There is water-swellable cushion rubber 5, run into rainy weather, the water-swellable of water-swellable cushion rubber 5, waterproof effect more preferably, is wound outside insulation tube
Non-flammable adhesive tape 3 is used to fire-proof and explosion-proof during insulation tube insulation breakdown.
In the present embodiment, the cap 2 is made with connecting tube 4 by silastic material, due to itself it is flexible can be complete
Full cladding is close to insulation tube, and good seal performance, its outer surface is additionally provided with hydrophobic layer, with waterproof action.
In the present embodiment, the insulative pipe sleeve is on support tube, and the support tube external diameter is not less than insulation bore,
The support tube is that zigzag shape support bar is wound hollow cylinder；During installation, the interior insulation tube for being cased with support tube is worn
Enter cable, extract support bar out, insulation tube elastic shrinkage compresses cable, and insulation tube periphery winds non-flammable adhesive tape 3, and two ends put cap
2, then be connected by connecting tube 4.
The foregoing is only preferred embodiment of the present utility model, it is all according to present utility model application the scope of the claims done it is equal
Deng change and modification, it should all belong to covering scope of the present utility model.
