Abstract

The utility model discloses a cable pyrocondensation dactylotheca, including sleeve pipe, vial and connecting piece, first link and second link are extended to the connecting piece both ends, connecting piece, first link, second link three's internal diameter is the same, the sleeve pipe cup joints at first link outsidely, the vial cup joints the outside at the second link. Pyrocondensation dactylotheca after the installation can closely be laminated with the cable, prevents that the aqueous vapor from getting into wherein, in the use, has safe and reliable's advantage, and simultaneously owing to increased the connecting piece, therefore the bulk strength of this heat shrinkage bush is higher, avoids warping because of the pyrocondensation situation of back, breaking occur between dactylotheca and the sleeve pipe.

Description

Thermal-shrinkage finger sleeve of cable

Technical field:

This utility model belongs to cable fitting technical field, especially relates to a kind of thermal-shrinkage finger sleeve of cable.

Background technology:

Pyrocondensation cable finger sleeve, is commonly called as thermal-shrinkage finger sleeve or pyrocondensation glove, gains the name with finger because being shaped like the palm of people, Using crosslinked polyolefin materials and PUR to be composited, be enclosed within multicore cable core bifurcation, heating is i.e. shunk, the heat of inwall Cable can tightly be clung by melten gel, plays waterproof and moistureproof sealing protective effect.Current thermal-shrinkage finger sleeve is usually present vial and set Between pipe after pyrocondensation deforms, the problem of the junction intensity step-down of the two, there is the biggest safety during long-term use Hidden danger.

Summary of the invention:

Technical problem to be solved in the utility model is: increases connector between sleeve pipe and vial, and then can ensure The overall of pyrocondensation vial uses intensity.

In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions: a kind of cable pyrocondensation Fingerstall, including sleeve pipe, vial and connector, described connector two ends are extended the first connection end and second and are connected end, described company Fitting, first connect end, second connect end three internal diameter identical, described casing pipe sleeve is connected on outside the first connection end, described finger Pipe box is connected on the outside of the second connection end.

As preferably, the described first outer surface connecting end and second connection both ends is disposed as incline structure, institute State the first connection end and the second angle of inclination connecting both ends outer surface is 8 °～15 °.

As preferably, the external diameter of described connector and first connects the difference wall more than sleeve pipe of the maximum outside diameter size of end Thickness, the external diameter of described connector and second connects the difference wall thickness more than vial of the maximum outside diameter size of end.

As preferably, at the mouth of pipe of described sleeve pipe and vial, it is provided with PUR.

As preferably, described vial is provided with at least two outfan, joint face between outfan on described vial It is set to the sphere caved inward.

As preferably, the material of described connector is insulant.

Compared with prior art, the thermal-shrinkage finger sleeve having the beneficial effect that after installation of the present utility model can be closely connected with cable tight Close, prevent aqueous vapor from entering wherein, in use, there is safe and reliable advantage, simultaneously because add connector, therefore The bulk strength of this heat-shrinkable T bush is higher, it is to avoid after deforming because of pyrocondensation between fingerstall and sleeve pipe, and the situation of fracture occurs.

Accompanying drawing illustrates:

Below in conjunction with the accompanying drawings this utility model is further illustrated.

Fig. 1 is the structural representation of this practicality.

Fig. 2 is the structural representation of connector.

In figure: 1, sleeve pipe；2, vial；3, connector；31, the first connector；32, the second connector；4, PUR.

Detailed description of the invention:

Below in conjunction with the accompanying drawings and this utility model is described in detail by detailed description of the invention:

A kind of thermal-shrinkage finger sleeve of cable as depicted in figs. 1 and 2, including sleeve pipe 1, vial 2 and connector 3, described connector 3 Two ends are extended the first connection end 31 and second and are connected end 32, and described connector 3, first connects end 31, second and connects end 32 3 The internal diameter of person is identical, and it is outside that described sleeve pipe 1 is socketed in the first connection end 31, and described vial 2 is socketed in outside the second connection end 32 Portion.

For being easy to further sleeve pipe 1 and vial 2 are separately mounted on the first connection end 31 and the second connection end 32, described First connects end 31 and the second outer surface connecting both ends 32 is disposed as incline structure, and described first connects end 31 and the Two angles of inclination connecting both ends 32 outer surface are 8 °～15 °.

The external diameter of described connector 3 and first connects the difference wall thickness more than sleeve pipe 1 of the maximum outside diameter size of end 31, institute The difference of the maximum outside diameter size that the external diameter and second stating connector 3 connects end 32 is more than the wall thickness of vial 2, uses this structure, Sleeve pipe 1 and vial 2 can also be played position-limiting action by the two ends of connector 3.

End 31, vial 2 and the sealing of the second connection end 32, described set is connected further for increasing sleeve pipe 1 and first PUR 4 it is provided with at the mouth of pipe of pipe 1 and vial 2.

Further in order to increase the overall use intensity of this thermal-shrinkage finger sleeve of cable, described vial 2 is provided with at least two Individual outfan, on described vial 2, joint face between outfan is set to the sphere caved inward, and uses this caving inward After spherical structure, even if joint face occurs to deform largely during heating between the outfan of fingerstall 2, also will not Cause large-area overstocking of materials, and then ensure that the smoothness shunk at this joint face.

It addition, in order to avoid there is electric leakage situation, the material of described connector 3 is insulant.

It is emphasized that: be the most only preferred embodiment of the present utility model, not this utility model appointed What pro forma restriction, every according to technical spirit of the present utility model, above example is made any simple modification, etc. With change and modification, all still fall within the range of technical solutions of the utility model.
