Description
Technical field
The utility model relates to fiber optic communication field, relates in particular to a kind of jet printing type water blocking optical cable of communications optical cable.
Background technology
Traditional optical cable mostly prevents that with the filled type stop water optical cable from vertically seeping water.The ointment that cable cream fill process then mostly adopts the pressure fill method to satisfy in the optical cable core is filled, and the greatest problem of this technology is to carry out the filling of steel (aluminium) band lap-joint, thereby causes vertical infiltration of steel (aluminium) band lap-joint.Aluminium strip, is easy to coincide so vertical bag faying surface is smooth because its matter is soft, not too can seep water usually.But steel band matter is hard, needs embossing before the vertical bag, thereby the vertical bag faying surface of wrinkle steel band is difficult to coincide, and always has some spaces therebetween and exists, and becomes in the optical cable core part of the easiest infiltration.This has become a main product quality problem of a lot of optical cable manufacturing enterprise.At present, for guaranteeing that the steel band lap-joint main solution that is adopted that do not seep water has: (one) is that the lap-joint's coating hot-melt adhesive at steel band guarantees blocking water of this part; This method is to utilize hot melt adhesive that the faying surface of steel band is bonded together, thereby eliminates the space in the faying surface fully, to preventing that the infiltration of steel band faying surface from being quite effective.But the performance and the control of hot melt adhesive coating equipment are had relatively high expectations, and the stability of control is not easy to hold.The not enough meeting of hot melt adhesive be seeped water, and hot melt adhesive too much overflows puts up the jacket surface quality that seam then will influence optical cable, and long-time the use, and can bring optical cable in metal tape vertical bag mould formation buildup easily influences the optical cable quality.(2) be that self-adhesion by the plastic coating of steel (aluminium) belt surface of metal tape lap-joint fetches and guarantees blocking water of this part; This method need be guaranteed the bonding fully of metal tape lap-joint, and this method is had relatively high expectations to the vertical wrap molding of metal tape, the multiple kinds of molds forming method that the optical cable industry usually adopts all be difficult to guarantee to accomplish the wrinkle steel band vertical wrap lap-joint fully from bonding.(3) be to fill by excessive ointment to guarantee that metal tape lap-joint fills sufficient ointment and make optical cable reach the block-water performance requirement; The very difficult control of the cable cream loading of this method, thus the phenomenon that meeting generation cable cream overflows from overlapping the slot in the production run influences the surface quality of optical cable, if cable cream can not overflow the possibility that can't guarantee that then lap-joint blocks water from overlapping the slot.Block water expansion cable cream cone penetration, absorbent time, expansion height, to analyse oil and gelling performance be examination several the important indicators that cable cream quality denys well that block water, and traditional cable cream cone penetration is big more, with regard to the easy more oil of analysing, and absorbent time is slow and degree of expansion is little, and suction back gelling performance is also bad; On the contrary, if cable cream to analyse oil good, absorbent time is fast and expansivity is high, the cone penetration of ointment is just smaller and viscosity is big, and gelling performance is also bad, is conflicting between them, both often can not get both.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of on the metal tape of communications optical cable spraying waterproof cable cream prevent the vertically jet printing type water blocking optical cable of infiltration.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical matters that solves the utility model adopts is: a kind of jet printing type water blocking optical cable, comprise: strengthening core, be evenly distributed with some optical fiber loose tubes or gasket for packing around the described strengthening core, be provided with optical fiber in described optical fiber loose tube or the gasket for packing, be provided with fine cream between described optical fiber loose tube or gasket for packing and the optical fiber, the outside of described optical fiber loose tube or gasket for packing and strengthening core is enclosed with metal tape, described metal tape outside surface is provided with the PE sheath, the vertical bag overlap joint in the two ends of described metal tape is filled with the cable cream that blocks water between described strengthening core and loose sleeve pipe or the gasket for packing.
According to an embodiment of the present utility model, the jet printing type water blocking optical cable comprises that further described metal tape is coated with the special type cable cream that blocks water by loose sleeve pipe or gasket for packing one side.
According to another embodiment of the present utility model, the jet printing type water blocking optical cable comprises that further described spraying method adopts continuous spraying method or intermittent spray mode.
According to another embodiment of the present utility model, the jet printing type water blocking optical cable further comprises between described metal tape and loose sleeve pipe or the gasket for packing and is filled with the cable cream that blocks water, and at the metal tape lap-joint lacquer special type cable cream that blocks water.
According to another embodiment of the present utility model, the jet printing type water blocking optical cable comprises that further described metal tape is aluminium strip or wrinkle steel band.
The utility model has solved the defective that exists in the background technology; the utility model evenly is sprayed on the metal tape by the cable cream that blocks water; make surfaces of metallic strip laterally continuously form the cross section (lap-joint that comprises metal tape) that cable cream blocks water thus stop water longitudinal stream mistake effectively; obtain the most effective optical cable water-blocking effect, particularly the optical cable to the steel band jacket structure has solved the problem of metal tape lap-joint through regular meeting's generation infiltration well.Because spraying waterproof cable cream has solved that the cone penetration of ointment wants big and viscosity wants little and absorbent time is fast and the contradiction of expansivity between high, has big cone penetration and little viscosity concurrently, and absorption speed is fast and suction after have certain expansion height and gelling performance.Make it have good spraying property, make optical cable both can realize vertically blocking water, also can save cable cream consumption, reduce the optical cable manufacturing cost.By continuous spraying method or intermittent spray mode, make that the water-ring structure in the cable core can prevent well that optical cable from vertically seeping water.
