Abstract
The utility model provides a breakable resin filling type thermal shrinkage joint for a communication cable, which comprises a metal neck bush which is formed by the connection through two half cylinders through a connecting piece, a thermal shrinkage layer which is formed by the connection of thermal shrinkage sheets coated on the exterior surface of the metal neck bush through the connecting piece, a plurality of connecting modules which are positioned in the metal neck bush, a shielding connecting wire of which both ends are respectively connected with a shielding layer of a cable which is to be connected, and a resin filling and sealing nozzle which is arranged on the thermal shrinkage layer and is respectively communicated with through holes on the thermal shrinkage layer and the metal neck bush; both ends of each connecting module are respectively connected with the core wire of the cable to be connected. The utility model has the advantages of good pressure resistance effect, good waterproof effect, good moistureproof effect, good fungusproof effect, good external force preventing effect, simple and fast construction, and the utility model can solve the disadvantage of two cable joints which are filled with air cores and factice.
Description
Technical field:
The utility model relates to a kind of pyrocondensation joint that cable cores continues and protects that is used for, and especially for waterproof, protection against the tide, mildew-resistant, anti-outside destroy, useful life is the pyrocondensation joint of the heart yearn joint protective of long important cable.
Background technology:
At present telecommunication cable (being divided into air-core cable and ointment filled cable) is had separately protected mode at continue joint after finishing of heart yearn: for the air-core cable is to charge into compressed air at the whole piece line-internal, portion forms the malleation that is higher than external pressure within it, thereby the mode that forms joint external and internal pressure difference prevents that extraneous water, moisture from entering, thereby protection joint, but this mode has just lost protective effect for ambient pressure greater than the occasion of air pressure inside, and it was both uneconomical to improve internal pressure, simultaneously cable life was also had adverse effect; Joint protective for petroleum jelly filled-type cable; be at the inner filled stone ointment of swagelok; thereby anti-sealing and moisture enter; play the effect of protection heart yearn; but the shortcoming of this mode is that the petroleum jelly intensity of its filling is very low, acts on inadequately for effectively resisting of outside destroy, will heat petroleum jelly when constructing simultaneously and could fill to the temperature flowing state; very trouble also has the danger of being scalded simultaneously.Therefore above-mentioned dual mode all has the improved place of needs, and a kind of universal product can be arranged is optimal.
The utility model content:
It is a kind of withstand voltage that the purpose of this utility model is to provide, and waterproof, protection against the tide, mildew-resistant, anti-outside destroy are effective, and the construction simple and fast can solve air-core and ointment and fill the telecommunication cable of two kinds of cable joint shortcomings with breaking resin filled-type pyrocondensation joint into two with one's hands.
The purpose of this utility model is achieved like this:
The utility model comprises the metal inner lining cover 4 that two semicircular cylinders is formed by connecting by connector, be wrapped in metal inner lining overlaps the shrink wrap layer 2 that the pyrocondensation sheet of 4 outer surfaces is formed by connecting by connector, the several two ends that are positioned at metal inner lining cover 4 respectively with the connecting module 6 of cable core 5 crimping of waiting to continue, the shielding connecting line 7 that two ends are connected with cable 1 screen 8 of waiting to continue respectively places the resin embedding mouth 15 that communicates with through hole 13 on shrink wrap layer 2, the metal inner lining cover 4 respectively on the shrink wrap layer 2.
Connector on the above-mentioned metal inner lining cover 4 is a hinge 18.
Above-mentioned metal inner lining overlaps tooth lobe 17 on 4 two ends, have metal inner lining cover 4 fixation adhesive tapes 3 that are fixed on the cable 1.
Above-mentioned shrink wrap layer 2 upper connectors are the overlap joint film 17 that is positioned at shrink wrap layer 2 circumferential ends, the muscle 14 that 10 engagings of stainless steel card article are arranged that makes progress in two ends week that lays respectively at shrink wrap layer 2.
Above-mentioned shrink wrap layer 2 inwalls have hot melt adhesive layer 9.
Embedding mouth cap 11 with matching is arranged on the above-mentioned embedding mouth 15.
The utility model has the advantages that: withstand voltage, waterproof, protection against the tide, mildew-resistant, anti-outside destroy are effective, use, the construction simple and fast, and dependable performance can solve air-core and ointment and fill two kinds of cable joint shortcomings.Can handle heart yearn easily once more, thereby all bring great convenience long service life for the project installation follow-up maintenance.

Embodiment:
The utility model telecommunication cable is with breaking resin filled-type pyrocondensation joint into two with one's hands, comprise the aluminum metal inner lining cover 4 that two semicircular cylinders is formed by connecting by hinge 18, be wrapped in the aluminum metal inner lining and overlap the shrink wrap layer 2 that the pyrocondensation sheet of 4 outer surfaces is formed by connecting by connector, the several two ends that are positioned at aluminum metal inner lining cover 4 respectively with the connecting module 6 of the cable 1 heart yearn crimping of waiting to continue, the shielding connecting line 7 that two ends are connected with cable 1 screen 8 of waiting to continue respectively, place on the shrink wrap layer 2 respectively with shrink wrap layer 2, the resin embedding mouth 15 that through hole 13 on the aluminum metal inner lining cover 4 communicates, the aluminum metal inner lining overlaps tooth lobe 17 on 4 two ends, have aluminum metal inner lining cover 4 fixation adhesive tapes 3 that are fixed on the cable 1, shrink wrap layer 2 upper connectors are the overlap joint film 17 that is positioned at shrink wrap layer 2 circumferential ends, lay respectively at the muscle 14 that 10 engagings of stainless steel card article are arranged that makes progress in two ends week of shrink wrap layer 2, scribble hot melt adhesive layer 9 on shrink wrap layer 2 inwalls, embedding mouth 15 has embedding mouth cap 11 with matching.
During use, at first with waiting to continue cable 1 screen 8 by 7 connections of shielding connecting line, with connecting module 6 with several cable core 5 crimping of waiting to continue, the aluminum metal inner lining cover 4 that two semicircular cylinders is formed by connecting by hinge 18 is wrapped in outside connecting module 6 and the shielding connecting line, again with fixation adhesive tape 3 fixedly the two ends of aluminium insert 4 on cable 1, then the through hole on the pyrocondensation sheet 2 is cooperated with embedding mouth 15 on the aluminium insert 4, hot melt adhesive layer 9 on the pyrocondensation sheet 2 is close to is wrapped on the aluminum metal inner lining cover 4, engage the 14 one-tenth cylindrical shapes of two ends muscle that make progress in 2 two ends weeks of shrink wrap layer with stainless steel card article 10, heat shrink then, pour into by embedding mouth 15 and can break resin 12 into two with one's hands, cover embedding mouth cap 11, joint is promptly finished.
