Abstract

The utility model relates to a positioning gluing heat-shrinkable bushing formed by the combination of an outer-layer bushing body (1) and an inner-layer hot melt adhesive layer (2). The inner wall part of the outer-layer bushing body (1) is covered by the inner-layer hot melt adhesive layer (2). One part of the inner wall of the outer-layer bushing body (1), which is not covered by the inner-layer hot melt adhesive layer (2), is designed as a non-gluing reservation segment (3). According to the embodiments of the utility model, during the application of the heat-shrinkable bushing, the sliding displacement of the heat-shrinkable bushing is prevented. In this way, the positioning gluing heat-shrinkable bushing is good in insulating property, water resistance, corrosion resistance, leakage resistance and other protection abilities for cable joints.

Description

A kind of location gluing thermal shrinkage sleeve pipe

Technical field

The utility model belongs to cable interconnection technique field, relates in particular to a kind of location gluing thermal shrinkage sleeve pipe.

Background technology

In recent years, the feature such as heat-shrinkable T bush (also claiming heat-shrink tube) is easy to use with it, be connected firmly, good insulating, was widely used in the connection procedure of the various cables such as power cable, communications optical cable.

Among all kinds of heat-shrinkable T bushs, double wall heat Heat-Shrinkable Tubings is widely used a kind of; As shown in Figure 1, it is composited by outer body 1 and internal layer hot melt adhesive layer 2; Wherein, outer body 1 adopts high-quality, soft cross-linked polyolefin material to make conventionally; there is the advantages such as insulating capacity is strong, antiseptic property good, wear-resisting; and internal layer hot melt adhesive layer 2 has the advantages such as low melting point, high adhesiveness, good airproof performance, waterproof ability are strong, the double wall heat Heat-Shrinkable Tubings of therefore integrated both advantages be widely used in to various cable connectors insulate, the protection such as waterproof, anticorrosion, anti-gas-leak.

In the prior art, the internal layer hot melt adhesive layer 2 of double wall heat Heat-Shrinkable Tubings all covers the inwall of outer body 1; But in actual use; after these PUR preheatings are melted; the PUR of molten condition can play certain lubrication; easily make outer body 1 that sliding transfer occurs; therefore may cause whole double wall heat Heat-Shrinkable Tubings to depart from original fixed position, thus reduced double wall heat Heat-Shrinkable Tubings to cable connector insulate, the ability of the protection such as waterproof, anticorrosion, anti-gas-leak.

Summary of the invention

The utility model provides a kind of location gluing thermal shrinkage sleeve pipe; so that make heat-shrinkable T bush in use; can there is not sliding transfer, thus can bring into play better heat-shrinkable T bush to cable connector insulate, the ability of the protection such as waterproof, anticorrosion, anti-gas-leak.

The purpose of this utility model is achieved through the following technical solutions:

A location gluing thermal shrinkage sleeve pipe, is composited by outer body 1 and internal layer hot melt adhesive layer 2; Internal layer hot melt adhesive layer 2 covers the inner wall section of outer body 1;

The part not covered by internal layer hot melt adhesive layer 2 on the inwall of outer body 1 is called not gluing reservation paragraph 3.

Preferably, gluing reservation paragraph 3 is not positioned at one end of outer body 1.

Preferably, not the length of gluing reservation paragraph 3 between 1～1000mm.

Preferably, internal layer hot melt adhesive layer 2 is at least one in hot melt packing element or PUR helix.

Preferably, the pitch of PUR helix is 0～30mm.

The technical scheme being provided by above-mentioned the utility model embodiment can be found out; the location gluing thermal shrinkage sleeve pipe that the utility model embodiment provides covers the inner wall section of outer body 1 by internal layer hot melt adhesive layer 2; and in use; first gluing reservation paragraph 3 is not heated; and never gluing reservation paragraph 3 beginnings are heated to the other end of outer body 1 gradually; thereby can avoid outer body 1 that sliding transfer occurs, so can bring into play better heat-shrinkable T bush to cable connector insulate, the ability of the protection such as waterproof, anticorrosion, anti-gas-leak.

Accompanying drawing explanation

Fig. 1 is the structural representation of double wall heat Heat-Shrinkable Tubings in prior art.

Fig. 2 is the structural representation one of location provided by the utility model gluing thermal shrinkage sleeve pipe.

Fig. 3 is the structural representation two of location provided by the utility model gluing thermal shrinkage sleeve pipe.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, be understandable that, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.

Below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.

Embodiment mono-

As shown in Figures 2 and 3, a kind of location gluing thermal shrinkage sleeve pipe, is composited by outer body 1 and internal layer hot melt adhesive layer 2; Internal layer hot melt adhesive layer 2 covers the inner wall section of outer body 1.

Wherein, the part not covered by internal layer hot melt adhesive layer 2 on the inwall of outer body 1 is called not gluing reservation paragraph 3; Gluing reservation paragraph 3 is not preferably positioned at one end of outer body 1, and its length is preferably between 1～1000mm.Internal layer hot melt adhesive layer 2 can be hot melt packing element (as shown in Figure 2), can be also PUR helix (as shown in Figure 3), can also in same internal layer hot melt adhesive layer 2, not only have hot melt packing element but also have PUR helix; When internal layer hot melt adhesive layer 2 comprises PUR helix; the pitch of PUR helix is preferably 0～30mm; thereby can make PUR can fill better the space between full cable connector and outer body 1 after thawing, to guarantee the Global Macros performance of heat-shrinkable T bush.

Particularly, in using this location gluing thermal shrinkage sleeve pipe process, can be first gluing reservation paragraph 3 be not heated, make not gluing reservation paragraph 3 shrink and be fixed on the cable that will protect, so that one end of outer body 1 is fixed; Then; never gluing reservation paragraph 3 beginnings are heated to the other end of outer body 1 gradually; thereby make this location gluing thermal shrinkage sleeve pipe be subject to gradually thermal contraction by this direction; so both can guarantee can not seal unnecessary gas up for safekeeping in this location gluing thermal shrinkage sleeve pipe; also can avoid outer body 1 that sliding transfer occurs, thus can bring into play better heat-shrinkable T bush to cable connector insulate, the ability of the protection such as waterproof, anticorrosion, anti-gas-leak.

Visible, the utility model embodiment makes heat-shrinkable T bush in use, sliding transfer can not occur, thus can bring into play better heat-shrinkable T bush to cable connector insulate, the ability of the protection such as waterproof, anticorrosion, anti-gas-leak.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
