Abstract
The utility model discloses and a kind ofly to take over in the water proof type integral type pyrocondensation of solder ring, be made up of with the solder ring be fixed in body twolayer firing shrinkage tube.Described heat-shrink tube is double-layer coextrusion heat-shrink tube, and internal layer is PUR, is directly bonded on cable by heating by heat-shrink tube; Described solder ring is coated with scaling powder, and when ensure that heating, solder ring is to the welding effect of connection cable joint.Above-mentioned shrinkable tube structure is simple, and sealing effectiveness is better, and welding point is more firm.
Description
Technical field
The utility model relates to heat-shrink tube field, particularly a kind ofly takes over in the water proof type integral type pyrocondensation of solder ring.
Background technology
When cable connects, joint often adopts electric iron to weld solder stick heating, has welded rear electrical adhesive tape and has wrapped up.The technical requirement of this mode of operation to welder is higher, and operation is also comparatively wasted time and energy, and outer electrical adhesive tape is easily aging to come off, and sealing effectiveness is difficult to ensure, finally causes the security incidents such as electric leakage, short circuit to occur.Patent CN203260438U discloses a kind of heat-shrink tube with function of shielding, and this heat-shrink tube body inner sleeve has tin ring, and both sides are provided with glue ring, realizes cable and connects, realize sealing by two glue rings by heating solder ring.In actual use, easily there is unstable phenomenon by heat gun heat welded plumb joint out in common solder ring, easily aging after both sides glue ring uses for a long time, affects sealing effectiveness.
Summary of the invention
The utility model, for the defect in prior art, provides that a kind of solder ring welds more firmly, both sides sealing effect is better a kind ofly takes over in the water proof type integral type pyrocondensation of solder ring.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
A kind ofly to take over in the water proof type integral type pyrocondensation of solder ring, its structure comprises: heat-shrink tube, internal layer PUR, soldering flux coating, solder ring, described internal layer PUR invests heat-shrink tube inwall, heat-shrink tube is round tube structure, heat-shrink tube center is provided with closing waist structure, described soldering flux coating is positioned over the closing waist position in the middle of heat-shrink tube, and soldering flux coating inner ring is provided with solder ring.
Described soldering flux coating is identical with the length of solder ring, and the outer surface of revolution of solder ring contacts with soldering flux coating, ensures that the electric wire after the peeling of two ends inserts length in copper pipe consistent and can not mutually extrude.
Described heat-shrink tube is double-layer coextrusion heat-shrink tube, and internal layer is internal layer PUR, has good water resistance, and heat-shrink tube firmly can be wrapped with wire outer skin, skin is semihard material, and make joint more firm, resistance to wear is better.
The utility model has the following advantages:
Take over location when location when eliminating electric wire connection, heat-shrink tube parcel in pyrocondensation of the present utility model, install more simple, quick.The heat-shrink tube of double-layer coextrusion, by the PUR of internal layer better achieve connect firm, waterproof is reliable.
Accompanying drawing explanation
Fig. 1 is of the present utility model a kind of with adapter overall structure schematic diagram in the water proof type integral type pyrocondensation of solder ring.
In figure: 1-heat-shrink tube, 2-internal layer PUR, 3-soldering flux coating, 4-solder ring.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1 of the present utility model a kind of takes over in the water proof type integral type pyrocondensation of solder ring, its structure comprises: heat-shrink tube 1, internal layer PUR 2, soldering flux coating 3, solder ring 4, described internal layer PUR 2 invests heat-shrink tube 1 inwall, heat-shrink tube 1 is round tube structure, heat-shrink tube 1 center is provided with closing waist structure, described soldering flux coating 3 is positioned over the closing waist position in the middle of heat-shrink tube 1, and soldering flux coating 3 inner ring is provided with solder ring 4; Described soldering flux coating 3 is identical with the length of solder ring 4, and the outer surface of revolution of solder ring 4 contacts with soldering flux coating 3, ensures that the electric wire after the peeling of two ends inserts length in copper pipe consistent and can not mutually extrude; Described heat-shrink tube 1 is double-layer coextrusion heat-shrink tube, and internal layer is internal layer PUR 2, has good water resistance, and heat-shrink tube 1 firmly can be wrapped with wire outer skin, skin is semihard material, and make joint more firm, resistance to wear is better.
During use, first will be coated with the solder ring 4 of soldering flux coating 3 in advance by being fixed on heat-shrink tube 1 to this section of heat-shrink tube 1 heat shrink; Then, by high-temperature heating, heat-shrink tube 1 shrinks and is fixed on protected connection cable, internal layer PUR 2 with heat-shrink tube 1 for double-layer coextrusion is extruded, be bonded in after heating together with heat-shrink tube 1 on cable, sealing effectiveness is better, prevents outside air, rainwater etc. from entering oxidation cable; Solder ring 4, by being welded together at cable connector two ends after heat fused, better ensures welding effect by soldering flux coating 3, obtains more firmly joint.
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.
