Abstract
The utility model relates to a pear-shaped heat shrinkable finger casing pipe which comprises a main casing pipe (11), a pear-shaped transition connecting pipe and at least two finger pipes (12), wherein the pear-shaped transition connecting pipe comprises a taper pipe (14), the small end of the taper pipe (14) is connected with the main casing pipe (11), the big end of the taper pipe (14) is connected with a spherical cap shell (13), the outside of the spherical surface of the spherical cap shell (13) is connected with each finger pipe (12), and each finger pipe (12) is communicated with the main casing pipe (11). The implementation of the embodiment in the utility model ensures that the heat shrinkable finger casing pipe does not crack in the producing and the using process so as to more effectively carry out insulation, sealing and protection to the bifurcating place of a cable, thereby reducing the potential safety hazard.
Description
Technical field
The utility model belongs to cable and wire interconnection technique field, relates in particular to a kind of pyriform pyrocondensation fingerstall pipe.
Background technology
In the connection procedure of cable (or electric wire), pyrocondensation fingerstall pipe is mainly used in the insulation and the seal protection at cable branch-off place; Common pyrocondensation fingerstall pipe has two core fingerstall pipes, three core fingerstall pipes, four-core fingerstall pipe and five core fingerstall pipes.As shown in Figure 1, the primary structure of existing pyrocondensation fingerstall pipe can comprise sleeve pipe 1 and at least one vial 2, and wherein, sleeve pipe 1 is straight tubular, and the one of which end is that tack sealed end 3, the other end are opening; Vial 2 all is located at the tack sealed end 3 of sleeve pipe 1, and connects each other with sleeve pipe 1.At present, there is following problem at least in existing pyrocondensation fingerstall pipe:
The first, in the production process of pyrocondensation fingerstall pipe, need be through the step of " caliber expansion "; Existing pyrocondensation fingerstall pipe is when carrying out " caliber expansion ", and its vial 2 with sleeve pipe 1 junction cracking takes place easily and scraps.
The second, in the use of pyrocondensation fingerstall pipe, also need be through the step of " pyrocondensation "; Because distance is too small between the vial of existing pyrocondensation fingerstall pipe, therefore existing pyrocondensation fingerstall pipe is when carrying out " pyrocondensation ", and its vial 2 with sleeve pipe 1 junction cracking takes place easily and scraps.
The 3rd, in the process of using pyrocondensation fingerstall pipe, between cable branch-off place and pipe box, there is air gap; Usually need fill insulating cement at the cable branch-off place; Will form the thick of part like this at the cable branch-off place, can cause the tack sealed end 3 of sleeve pipe 1 when heat shrink, can not bounce back fully thus, be in for a long time under the tension force effect; The overall mechanical strength of fingerstall 2 will reduce; The vial 2 of therefore existing pyrocondensation fingerstall pipe is scrapped with regard to very easily cracking taking place with sleeve pipe 1 junction, and then loses insulation and seal protection effect, forms potential safety hazard.
Summary of the invention
The utility model provides a kind of pyriform pyrocondensation fingerstall pipe, so that pyrocondensation fingerstall pipe all can not ftractureed in production and use, thus can more effectively insulate, seal and protect the cable branch-off place, reduce potential safety hazard.
The purpose of the utility model realizes through following technical scheme:
A kind of pyriform pyrocondensation fingerstall pipe comprises: main sleeve pipe 11, pyriform transition are taken over and two vials 12 at least;
The pyriform transition is taken over and is comprised a Taper Pipe 14, and the Taper Pipe small end connects main sleeve pipe 11, and the big end of Taper Pipe connects a spherical crown shell 13, and the sphere of spherical crown shell 13 connects each vial 12 outward; Each vial 12 is communicated with said main sleeve pipe 11.
Preferably, the number of corresponding vial 12 is 2,3,4,5,6,7,8,9 or 10.
Preferably, corresponding at least two vials 12 are distributed on the sphere of spherical crown shell.
Technical scheme by above-mentioned the utility model embodiment provides can be found out; The utility model embodiment is provided with pyriform changeover portion 14 at an end of sleeve pipe 11; And change seal face into protruding sphere by the plane, thereby increased the space of 12 of vials, make pyrocondensation fingerstall pipe produce and use in all can not ftracture; And can more effectively insulate, seal and protect, reduce potential safety hazard the cable branch-off place.

Fig. 2 is the structural representation of the pyriform pyrocondensation fingerstall pipe that the utility model provided.
Embodiment
To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, intactly description; It is understandable that described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
To combine accompanying drawing that the utility model embodiment is done to describe in detail further below.
Embodiment one
As shown in Figure 2, a kind of pyriform pyrocondensation fingerstall pipe, its concrete structure can comprise: main sleeve pipe 11, pyriform transition are taken over and two vials 12 at least;
The pyriform transition is taken over and is comprised a Taper Pipe 14, and the Taper Pipe small end connects main sleeve pipe 11, and the big end of Taper Pipe connects a spherical crown shell 13, and the sphere of spherical crown shell 13 connects each vial 12 outward; Each vial 12 is communicated with said main sleeve pipe 11.
Wherein, the number of corresponding vial 12 is 2,3,4,5,6,7,8,9 or 10, but in real life, can select according to actual needs to produce.Corresponding at least two vials 12 are distributed on the sphere of spherical crown shell.
Particularly; Because the sphere of spherical crown shell 13 connects each vial 12 outward; And this structure has strengthened the distance of vial 12; So the pyriform pyrocondensation fingerstall pipe that the utility model provided is when carrying out " caliber expansion " or " pyrocondensation ", can not ftracture in the junction of the sphere of spherical crown shell 13 and vial 12.Simultaneously; Main sleeve pipe 11 is connected with spherical crown shell 13 through a pyriform transition adapter; Therefore can better adapt to the local thick shape of having filled insulating cement at the cable branch-off place and having formed; Having eliminated the pyrocondensation fingerstall pipe range phase is in the danger that causes overall mechanical strength to reduce under the tension force effect, for cable branch-off provides better insulation and seal protection effect.
It is thus clear that the realization of the utility model embodiment can make pyrocondensation fingerstall pipe in production and use, all can not ftracture, thereby can more effectively insulate, seal and protect the cable branch-off place, reduces potential safety hazard.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
