Abstract
The utility model relates to an optical cable, in particular to a covered optical cable which is suitable to be laid and connected indoors and is easy to be branched. The optical cable is composed of a protective layer, a strengthened core and an optical fiber, the cross section of the protective layer is quasi-8-shaped, an optical fiber hole is disposed at the near-middle position of two half portions, the optical fiber is inserted in the optical fiber hole, a strengthened core hole is disposed at the center of the cross section, and the strengthened core is inserted in the strengthened core hole. The covered optical cable is easy to be bended and branched, after being branched, optical fibers in each branched section are still protected by the protective layer, and the optical fibers are easier to be in branched connection, simultaneously, the whole covered wire is mechanically protected by the strengthened core. Further, the flat quasi-8-shaped protective layer of the covered optical cable can bear relatively large lateral pressure. Therefore, the covered optical cable is extremely suitable for being used in fiber access indoors.
Description
Technical field
The utility model relates to a kind of optical cable, relates in particular to a kind of indoor easy to be dichotomous covered wire cable that lays, connects that is adapted at.
Background technology
In recent years, along with developing rapidly of optical fiber access technology, the demand of various inside cables also increases thereupon, and wherein, covered wire cable has obtained using widely because of the advantage of himself quite is subjected to people's favor.Conventional at present covered wire cable is made up of sheath, reinforcement and optical fiber three parts, and wherein optical fiber is naked fibre, is in the rubber-insulated wire center by among the formed optic fibre hole of sheath, forms loose nested structure, and optical fiber can not stress; In the sheath of optic fibre hole both sides, then be interspersed with reinforcement respectively.This covered wire cable is the flat structure; its installation under indoor various occasions is laid all very flexible; but its defective is: because several optical fiber are in together in the optic fibre hole at rubber-insulated wire center; thereby in use the bifurcated of optical fiber is connected and cause certain difficulty; after rubber-insulated wire was peeled off along center line, fibre bundle had then lost the protective effect of sheath and reinforcement.
The utility model content
The technical problems to be solved in the utility model is: in order to overcome existing above-mentioned deficiency of existing conventional covered wire cable and defective, provide a kind of easily dichotomous covered wire cable.
The technical solution adopted in the utility model is: a kind of easy dichotomous covered wire cable, form by sheath, strengthening core and optical fiber, the shape of described its section of sheath 8 fonts that are as the criterion, the position has optic fibre hole in two and half ones near, be interspersed with optical fiber in the optic fibre hole, the center of section has the strengthening core hole, and strengthening core is interspersed with strengthening core in the hole.
Say that further described sheath is made by PVC material or flame retardant polyolefine material or polyurethane material.
Described strengthening core is made by glass-reinforced plastic material or aramid fiber rod or steel wire or copper wire.
The beneficial effects of the utility model are: this covered wire cable is easy to bending, is easy to bifurcated, and the optical fiber behind the bifurcated in each bifurcated section still is subjected to the protection of sheath, and the easier branch that carries out of optical fiber connects, and the mechanical protection that a whole simultaneously rubber-insulated wire still is in strengthening core on.In addition, the sheath of accurate 8 fonts of its flat of this covered wire cable can bear bigger wall pressure.Therefore, this covered wire cable extremely is suitable for using in indoor optical fiber inserts.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation behind the covered wire cable bifurcated of the present utility model.
Fig. 3 is the section structure synoptic diagram of the covered wire cable of present routine.

Embodiment
A kind of easy dichotomous covered wire cable as shown in Figure 1, form by sheath 1, strengthening core 2 and optical fiber, the shape of described sheath 1 its section 8 fonts that are as the criterion, the position has optic fibre hole in two and half ones near, be interspersed with optical fiber 3 in the optic fibre hole, the center of section has the strengthening core hole, is interspersed with strengthening core 2 in the strengthening core hole.
Described sheath 1 is made by PVC material or flame retardant polyolefine material or polyurethane material.
Described reinforcing core member 2 is made by glass-reinforced plastic material or aramid fiber rod or steel wire or copper wire.
This covered wire cable is easy to bending, is easy to bifurcated, and the optical fiber behind the bifurcated in each bifurcated section still is subjected to the protection of sheath, and the easier branch that carries out of optical fiber connects, and the mechanical protection that a whole simultaneously rubber-insulated wire still is in strengthening core on.In addition, the sheath of accurate 8 fonts of its flat of this covered wire cable can bear bigger wall pressure.Therefore, this covered wire cable extremely is suitable for using in indoor optical fiber inserts.
The strengthening core of this covered wire cable is if adopt copper wire, but then copper wire double as signal wire or supply lines.
Claims (3)
1. easy dichotomous covered wire cable, form by sheath (1), strengthening core (2) and optical fiber (3), it is characterized in that: the shape of its section of described sheath (1) 8 fonts that are as the criterion, the position has optic fibre hole in two and half ones near, be interspersed with optical fiber (3) in the optic fibre hole, the center of section has the strengthening core hole, is interspersed with strengthening core (2) in the strengthening core hole.
2. easy dichotomous covered wire cable according to claim 1 is characterized in that: described sheath (1) is made by PVC material or flame retardant polyolefine material or polyurethane material.
3. easy dichotomous covered wire cable according to claim 1 is characterized in that: described strengthening core (2) is made by glass-reinforced plastic material or aramid fiber rod or steel wire or copper wire.
