Abstract
The utility model discloses a kind of jacket layer material that prevents and meet the water blocking optical cable of cold events, comprise conduit, the first yarn of spiral winding reinforced wire, the second yarn of spiral winding conduit, separator tube, water blocking layer and the first restrictive coating; Described conduit comprises reinforced wire and is close to the second restrictive coating of reinforced wire; Described first yarn is arranged between reinforced wire and the second restrictive coating; Described separator tube is looped around surrounding catheter and covers described second yarn; Described first restrictive coating covers described separator tube.The utility model has water stop function, and can realize producing fast.
Description
Technical field
The utility model relates to a kind of water blocking optical cable preventing jacket layer material from meeting cold events, is applicable to fiber optic cable communications field.
Background technology
In conventional art, some optical cable its jacket layer material when meeting cold can shrink, thus restrictive coating and reinforced wire depart from, in the gap causing water to infiltrate between restrictive coating and reinforced wire.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of water blocking optical cable preventing jacket layer material from meeting cold events, solves conventional cable jacket layer material and meets cold events and cause oozing water problem.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of water blocking optical cable preventing jacket layer material from meeting cold events, comprises conduit, the first water swellable yarn, the second water swellable yarn, separator tube and the first restrictive coating; Conduit internal layer center of telling arranges bar shape reinforced wire, and skin arranges the second restrictive coating; Described first water swellable yarn to be arranged between reinforced wire and the second restrictive coating and to be spirally wound on the outside surface of reinforced wire; Described second water swellable yarn is spirally wound on the outside surface of conduit; Described separator tube supports to strand optical fiber, is looped around surrounding catheter and covers described second water swellable yarn; Described first restrictive coating covers described separator tube, and and be provided with water blocking layer between separator tube; Wherein said water blocking layer outside surface arranges sheath rip-cord, and inside surface is close to separator tube by bonding agent; The spiral wound direction of first, second water swellable yarn described and bonding agent can be identical or contrary.
Preferably, the outside surface of described second restrictive coating can arrange nylon or ethylene-based layer; Preferably, the longitudinal axis of described reinforced wire and the longitudinal axis of described optical cable are parallel to each other or conllinear.Described first water swellable yarn linearly can be placed along reinforced wire side in other embodiments, and its lay pitch is determined according to yarn package size, and the preferred lay pitch is less than 1m.
The beneficial effects of the utility model are: can realize quick production, save production cost; Can prevent jacket layer material from meeting cold events, thus realize water stop function.

Wherein, 110-optical cable; 112-conduit; 114,116-water swellable yarn; 118-separator tube; 120,126-optical fiber; 122-polymer jacket layer; 124-reinforced wire; 128-water blocking layer; 130-sheath rip-cord; 132-bonding agent.
Embodiment
By reference to the accompanying drawings, the utility model is described in further detail.
See Fig. 1, the utility model optical cable 110 comprise conduit 112, spiral wound conduit 112 outside surface water swellable yarn 114, to be looped around around conduit 112 and to cover the separator tube 118 of water swellable yarn 114 and cover the polymer jacket layer 122 of separator tube 118; Wherein said separator tube 118 supports to strand optical fiber 120; Tell conduit 112 internal layer center bar shape reinforced wire 124 and the spiral wound water swellable yarn 116 at reinforced wire 124 outside surface be set, skin arranges polymer jacket layer 122.
Arrange water blocking layer 128 between described separator tube 118 and polymer jacket layer 122, water blocking layer 128 outside surface arranges sheath rip-cord 130, and inside surface is close to separator tube 118 by bonding agent 132; The spiral wound direction of wherein said water swellable yarn 114,116 and bonding agent 132 can be identical or contrary.
Preferably, the outside surface of described polymer jacket layer 122 can arrange nylon or ethylene-based layer; Preferably the longitudinal axis of described reinforced wire 124 and the longitudinal axis of described optical cable 110 are parallel to each other or conllinear.Described water swellable yarn 116 linearly can be placed along reinforced wire 124 side in other embodiments, and its lay pitch is determined according to yarn package size, and the preferred lay pitch is less than 1m.
