Description
Technical field
This utility model relates to the double-deck cold shrink tube of a kind of brand new.
Background technology
The seal protection cover that domestic communication base station major part cable uses is silica gel cold shrink tube, because of its physical and mechanical properties relatively
Difference, lear energy is more weak, is weak to puncture, wears no resistance, and need cable jumper wire is carried out before installing pre-twine filling sponge or
Using clay filling to process, operation is more, operates very inconvenient, and under relatively harsh environment, its use has limitation.
Although EP rubbers cold shrink tube product thorn resistance is good at present, but its-20 ° of below C low temperature environment shrinkages
Poorer than silicone rubber cold shrink tube, and due to during storing cold shrink tube not in place, finally because rubber molecule elastic loss causes bouncing back
Waterproof sealing protection requirement cannot be met.
Therefore, can use at-20 ° of below C low temperature environments for reaching EP rubbers cold shrink tube, and during longer-term storage
Do not lost efficacy, and solved silica gel cold shrink tube material simultaneously and be weak to the problem of puncture, the second third of developing a kind of built-in silica gel tube is presently required
Rubber bilayer cold shrink tube.
Utility model content
The technical problems to be solved in the utility model is: overcome silica gel cold shrink tube can not meet the installation question of resistance to puncture and
The problem solving EP rubbers cold shrink tube storing process elastic loss, it is provided that the EP rubbers bilayer shrinkage of a kind of built-in silica gel tube
Pipe, it can solve to shrink rapidly under-20 ° of below C low temperature environments by built-in silica gel tube, reaches product and seals waterproof requirement.
In order to solve above-mentioned technical problem, the utility model proposes techniques below scheme: the second third of a kind of built-in silica gel tube
Rubber bilayer cold shrink tube, including stay tube, built-in layer of silica gel, an EP rubbers main body tube；
Propping up stay tube is around forming by a supporting line body, and a stay tube is columnar；
The inside of stay tube leaves a withdrawal cord being connected with supporting line body or direct supporting line body does withdrawal cord；
Built-in layer of silica gel is set in the front end of a stay tube, and built-in layer of silica gel relies on the extruding of its elastic-restoring force attached after expansion
Outside a stay tube；
EP rubbers main body tube is set in outside a stay tube and built-in layer of silica gel, and EP rubbers main body tube relies on after expansion
The extruding of its elastic-restoring force is attached to outside a stay tube and built-in layer of silica gel；
EP rubbers main body tube and built-in layer of silica gel are all support by a stay tube；
Built-in layer of silica gel is between EP rubbers main body tube and a stay tube.
Technique scheme limits further and is, built-in layer of silica gel is positioned at the 5-foremost of distance EP rubbers main body tube
The position of 10mm.
Technique scheme limits further and is, built-in layer of silica gel is that superelevation expands multiplying power silicone insulation pipe.
Technique scheme limits further and is, the 1/8 of a length of EP rubbers main body tube length of built-in layer of silica gel.
Technique scheme limits further and is, the material of EP rubbers main body tube is EP rubbers, and material is black.
Compared with prior art, this utility model has the advantages that
1, bimetallic tube physical and mechanical properties is excellent, resistance to puncture, and moisture seal superior performance solves silica gel cold shrink tube and is weak to
The shortcoming such as puncture；
2, without heating or specialist tools, operating procedure is installed simple.
3, expansion multiplying power reaches about 4.5 times, and radial pressure is big, is suitable for being tightly connected of different size communication coaxial cable.
4, after bimetallic tube longer-term storage, due to the effect of built-in silica gel tube, its-20 ° of below C low temperature environments still possess high returning
Elasticity, is made without at wire jumper being wound around adhesive tape or using clay to fill, also can reach to seal waterproof requirement.

Detailed description of the invention
As shown in Fig. 1 and Fig. 4, the utility model proposes the EP rubbers bilayer cold shrink tube of a kind of built-in silica gel tube, its bag
Include stay tube 1, built-in layer of silica gel 2, an EP rubbers main body tube 3.
Propping up stay tube 1 is around forming by a supporting line body 101, and a stay tube 1 is columnar.
The inside propping up stay tube 1 is left a withdrawal cord 103 being connected with supporting line body 101 or directly uses supporting line body
101 do withdrawal cord.
Built-in layer of silica gel 2 is set in the front end of a stay tube 1.
Built-in layer of silica gel 2 relies on the extruding of its elastic-restoring force to be attached to outside a stay tube 1 after expansion.
Built-in layer of silica gel 2 is positioned at the position of the 5-10mm foremost of distance EP rubbers main body tube 3.
Built-in layer of silica gel 2 expands multiplying power silicone insulation pipe, the 1/8 of its a length of EP rubbers main body tube 3 length for superelevation
Left and right, the size of its thickness television cable rope skipping 4 is from Row sum-equal matrix.
The material of built-in layer of silica gel 2 is Lycoperdon polymorphum Vitt or light/dark balance or the color close with EP rubbers main body tube 3.
The material of EP rubbers main body tube 3 is EP rubbers, and material is black.
EP rubbers main body tube 3 is set in outside a stay tube 1 and built-in layer of silica gel 2.
EP rubbers main body tube 3 relies on the extruding of its elastic-restoring force to be attached to stay tube 1 and a built-in layer of silica gel 2 after expansion
Outward.
EP rubbers main body tube 3 and built-in layer of silica gel 2 are all support by a stay tube 1.
Built-in layer of silica gel 2 is between EP rubbers main body tube 3 and a stay tube 1.
During use, cable rope skipping 4 and sheath shrinkable sleeve 5 are inserted into the inside of a stay tube 1.Slowly pump the pull of a stay tube 1
Rope 103, EP rubbers main body tube 3 starts retraction, and wraps up sheath shrinkable sleeve 5 after losing the supporting role of supporting line body 101.When
The when that withdrawal cord 103 being extracted at built-in layer of silica gel 2, built-in layer of silica gel 2 has precedence over EP rubbers main body tube 3 and bounces back, built-in silicon
Glue-line 2 directly wraps up cable rope skipping 4, is equivalent to thicken the external diameter of cable rope skipping 4, and then EP rubbers main body tube 3 directly wraps up
In built-in layer of silica gel 2.
Complete the work progress of whole bimetallic tube, repeat to start said process.
Compared with prior art, this utility model has the advantages that
1, the physical and mechanical properties of bimetallic tube is excellent, resistance to puncture, and moisture seal superior performance solves silica gel cold shrink tube not
The resistance to shortcoming such as puncture；
2, without heating or specialist tools, operating procedure is installed simple.
3, expansion multiplying power reaches about 4.5 times, and radial pressure is big, is suitable for being tightly connected of different size communication coaxial cable.
4, after bimetallic tube longer-term storage, due to the effect of built-in silica gel tube, its-20 ° of below C low temperature environments still possess high returning
Elasticity, is made without at wire jumper being wound around adhesive tape or using clay to fill, also can reach to seal waterproof requirement.
