Abstract
The utility model discloses a kind of pyrocondensation sealing cap, be made up of outer sealing cap and internal layer PUR.Described sealing cap is that double wall heat Heat-Shrinkable Tubings one end is shunk in advance, and adds the shutoff of PUR bar and form.This product is that electric wire connects end, is that waterproof sealing process is the most reliable, most convenient mode efficiently, can better provides protective effect; Described hot melt adhesive layer is polyamide PUR, and large glue amount and excellent flowing fillibility, High performance hot melt adhesive can provide reliable water resistance and sealing effectiveness.
Description
Technical field
The utility model relates to a kind of pyrocondensation sealing cap, belongs to cable fitting field.
Background technology
At the end of cable, often need to provide dust-proof, the insulation sealing cap of moisture protection, adopt the sealing cap that simple material contracting with heat makes; be rolled on cable outer surface after heating; easily after having grown service time to peel off from cable surface, cause air, rainwater etc. to enter, oxidation cable.And adopt the insulation sealing cap of internal layer PUR, when heating owing to having mobility before PUR solidification, easily making whole sealing cap slide thereupon, cannot be fixed in desired location, affecting sealing effectiveness.Therefore need to find the pyrocondensation sealing cap that a kind of sealing effectiveness is better, practice of construction operation is more simple and efficient.
Summary of the invention
The utility model, for the defect in prior art, provides a kind of operation more easy, the better pyrocondensation sealing cap of sealing effectiveness.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind of pyrocondensation sealing cap, its structure comprises hot melt adhesive tape, shrink wrap layer, hot melt adhesive layer, shrink wrap layer and hot melt adhesive layer are circular tube structure, described hot melt adhesive layer invests the inner side of shrink wrap layer, shrink wrap layer and hot melt adhesive layer are coaxial placement, shrink wrap layer and hot melt adhesive layer one end are closing-in structure, and described hot melt adhesive tape is positioned at the closing-in structure of shrink wrap layer and hot melt adhesive layer one end, and described hot melt adhesive tape length equals the length of the closing-in structure of shrink wrap layer and hot melt adhesive layer one end.
Described hot melt adhesive layer is that heavy wall glue-line forms, and can better play the effect of being filled with a sealing.
Described hot melt adhesive layer is polyamide PUR, is spirally coated on shrink wrap layer inner surface, can provide reliably water resistance and sealing effectiveness.
Described hot melt adhesive layer also adopts single-ended portion without gluing mode, better fixes sealing cap unlikely with the PUR slip before solidification, shrinks in advance in one end endoporus of described shrink wrap layer after filling hot melt adhesive tape, form high sealing water proof type sealing cap end during constructability operation.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of a kind of pyrocondensation sealing cap of the present utility model.
In figure: 1 hot melt adhesive tape, 2 shrink wrap layer, 3 hot melt adhesive layers.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
Of the present utility model a kind of pyrocondensation sealing cap as shown in Figure 1, its structure comprises hot melt adhesive tape 1, shrink wrap layer 2, hot melt adhesive layer 3, shrink wrap layer 2 and hot melt adhesive layer 3 are circular tube structure, described hot melt adhesive layer 3 invests the inner side of shrink wrap layer 2, shrink wrap layer 2 and hot melt adhesive layer 3 are coaxial placement, shrink wrap layer 2 and hot melt adhesive layer 3 one end are closing-in structure, described hot melt adhesive tape 1 is positioned at the closing-in structure of shrink wrap layer 2 and hot melt adhesive layer 3 one end, and described hot melt adhesive tape 1 length equals the length of the closing-in structure of shrink wrap layer 2 and hot melt adhesive layer 3 one end; Described hot melt adhesive layer 3 forms for heavy wall glue-line, can better play the effect of being filled with a sealing; Described hot melt adhesive layer 3 is polyamide PUR, is spirally coated on shrink wrap layer 2 inner surface, can provide reliably water resistance and sealing effectiveness; Described hot melt adhesive layer 3 also adopts single-ended portion without gluing mode, better fixes sealing cap unlikely with the PUR slip before solidification, pre-contraction after filling hot melt adhesive tape 1 in the endoporus of described shrink wrap layer 2 one end, form high sealing water proof type sealing cap end during constructability operation.
During use; pyrocondensation sealing cap is enclosed within the end of cable; first hot melt adhesive layer 3 is heated; shrink wrap layer 2 is made first to be fixed on pipe to be protected; then sequentially heated towards sealing cap head by hot melt adhesive layer 3; firmly be fixed on pipe to be protected until whole pyrocondensation protective casing shrinks, high performance hot melt adhesive tape 1 can provide reliably waterproof and sealing effectiveness.
Above-described embodiment is better embodiment of the present utility model; but execution mode of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; the substitute mode of equivalence all should be considered as, be included within protection range of the present utility model.
