Abstract
The utility model relates to a flat type indoor optical cable with a parallel steel wire, in particular to a transmission line that is used in communication transmission line, transmission line of transmission device and transmission line of the telephone device as well as the transmission line of data processing device in a communication network transmission line and dwelling construction building as well as dwelling construction rooms. The utility model comprises a flat type protective sheath, a tightly packaged fiber unit and a paralleled steel wire. The flat type protective sheath is provided with a tightly packaged fiber unit, which is composed of an optical fiber or a plurality of optical fibers and is tightly packaged inside the flat type protective sheath. The two laterals of the tightly packaged fiber unit have paralleled steel wires, the central line of each steel wire is positioned in the same plane with the central line of the tightly packaged fiber unit.
Description
Technical field
What the utlity model has that the platypelloid type inside cable of parallel steel wire relates to is a kind ofly to be applicable in communication network transmission line, the residential building or communication transmission line, the transmission line of transmission equipment, the transmission line of telephone plant and the transmission line of data processing equipment between residential housing.
Background technology
The reinforcement of inside cable setting at present is generally non-metal reinforcement member, and as aramid fiber, FRP etc., intensity is relatively low, influences the tensile strength and the bending resistance of optical cable, can cause the stressed easily or optical cable fracture of optical fiber in the optical cable when being subjected to external force.The manufacturing cost of inside cable is higher at present.
Summary of the invention
The utility model purpose is to provide a kind of platypelloid type inside cable with parallel steel wire at above-mentioned weak point, has the platypelloid type oversheath, tightly packaged fiber unit is arranged in the oversheath, there is parallel steel wire the tightly packaged fiber unit both sides, improved tension, the bending resistance of optical cable, manufacturing cost is also relatively low.
Platypelloid type inside cable with parallel steel wire takes following scheme to realize:
Platypelloid type inside cable structure with parallel steel wire comprises pancake oversheath, tightly packaged fiber unit and parallel steel wire, in the pancake oversheath, be provided with tightly packaged fiber unit, tightly packaged fiber unit is made up of single or some optical fiber, hard-pressed bale is in the pancake oversheath, be provided with parallel steel wire in the tightly packaged fiber unit both sides, parallel steel wire center line and tightly packaged fiber unit center line are in the same plane.
Platypelloid type inside cable performance and characteristics with parallel steel wire:
1, parallel steel wire improves the tensile property of optical cable
2, parallel steel wire improves the lateral pressure resistant performance of optical cable
3, parallel steel wire improves the shock resistance of optical cable
4, the splendid photo-cured coating of performance guarantees extremely low decay
5, the optical fiber hard-pressed bale unit cushion of oversheath connection is easy to divest
6, the platypelloid type inside cable softness of parallel steel wire is improved
Description of drawings
The utility model is described in further detail below with reference to accompanying drawing:
Fig. 1 is the platypelloid type inside cable structural representation with parallel steel wire.
Embodiment
The platypelloid type inside cable structure that has parallel steel wire with reference to dimensional drawing 1 comprises pancake oversheath 1, tightly packaged fiber unit 3, parallel steel wire 2, be provided with tightly packaged fiber unit 3 in pancake oversheath 1 inside, tightly packaged fiber unit 3 hard-pressed bales are in pancake oversheath 1, be provided with parallel steel wire 2 in tightly packaged fiber unit 3 both sides, the pancake oversheath can adopt flame retarded polymeric materials such as tygon, polypropylene, Polyvinylchloride to make.
Claims (3)
1, a kind of platypelloid type inside cable with parallel steel wire, it is characterized in that structure comprises pancake oversheath, tightly packaged fiber unit, parallel steel wire, in the pancake oversheath, be provided with tightly packaged fiber unit, be provided with parallel steel wire in the tightly packaged fiber unit both sides.
2, the platypelloid type inside cable with parallel steel wire according to claim 1 is characterized in that tightly packaged fiber unit is made up of single or some optical fiber.
3, according to claim 1 have a parallel steel wire platypelloid type inside cable, it is characterized in that parallel steel wire center line and tightly packaged fiber unit center line are in the same plane.
