Background technology
Along with people improve constantly communication speed and quality requirements, optical communication obtains greatly expansion.Wherein, optical fiber is widely used because of satisfying in the signal transmission fast with demand such as wideband, and normal employing optical cable is realized the transmission of light signal in the current optical communication.Optical cable generally comprises multifiber, optical cable can be divided into loose tube cable, tight jacketed cable etc. according to surface.
Usually wrap bundle optical fiber in the optical cable, and need bear coarse processing or stretching and extruding etc. usually the optical cable inner fiber is in the physical environment of stress, for example, when needing coil when the optical cable bending or because of storage, the optical fiber in the optical cable promptly bears corresponding pressure or pulling force; In addition, different elements part (as the sleeve pipe or the optical fiber ribbon cable protective seam of optical fibre) also can produce mechanical tension because of different expansion coefficient in the optical cable, and the tension force that these factors produced very easily makes optical fiber impaired, and then influences the Optical Fiber Transmission performance.
For fixing and protection optical fiber injury-free, in multifiber need be packed into usually protection overcoat or other protective material.In addition, multifiber in groups constriction also can increase transinformation except that increasing the tensile strength.
Column optical fiber uses the supplementary protection layer to reduce the influence to optical fiber of tensile force or tension force usually; as single fiber being installed in a protection valve jacket or fiber groupings is installed in the sheath, the protection overcoat that this type of protective seam generally includes separator tube, enhancement Layer, filling layer and makes with poly-atmosphere ethene materials such as (PVC).Yet; for optical fiber ribbon cable, because of wherein optical fiber is to be arranged in parallel side by side, the protected mode that adopts is as filling protective seam and infeasible usually; and the cushion that single fiber adopts usually and the method for enhancement Layer also can not fully realize the protection to optical fiber in the optical fiber ribbon cable.
In recent years, along with developing rapidly of FTTX, the demand of the inside cable of various types increases day by day, and wherein covered wire cable has obtained development particularly rapidly, as the rubber-insulated wire of entering the room from the open air introducing, adopts the self-bearing type structure.Conventional self-bearing type covered wire cable as shown in Figure 1, it is by strengthening core 2, optical fiber 1, protective seam 4 and messenger wire steel wire 3, four parts are formed.Wherein optical fiber 1 is in the rubber-insulated wire center, among the micropore that is formed by protective seam 4, becomes a kind of loose nested structure.Optical fiber can not stress.2 both sides that are embedded in protective seam 4 respectively of strengthening core, the optical fiber in the rubber-insulated wire is naked fibre, the core number can from 1 to 4 wait.3 on messenger wire steel wire is positioned at protective seam 4 one sides.This rubber-insulated wire is owing to its flat structure, and the installation under indoor various occasions is laid very flexible.But because several optical fiber 1 are in together in the micropore of center, in use, the bifurcated of optical fiber 1 connects difficulty, and after peeled off at the rubber-insulated wire center, 2 pairs of optical fiber 1 of the strengthening core of both sides lost the mechanical protection effect.

For the defective that overcomes, the technical problems to be solved in the utility model is: propose a kind of self-bearing type covered wire cable that is easy to the novel structure of bifurcated.
The technical scheme that the utility model adopted is: a kind of self-bearing type covered wire cable that is easy to bifurcated; comprise at least two and the optical fiber of column alignment; one strengthening core and a stress buffer structure, a protective seam; this protective seam is into a single integrated structure with this optical fiber, strengthening core and stress buffer construction packages; wherein this optical fiber is symmetrically distributed in the both sides of this strengthening core; have an optical fiber at least between stress buffer structure and strengthening core, be formed with groove between this optical fiber and strengthening core, the buffer structure respectively.
According to another one embodiment of the present utility model, the self-bearing type covered wire cable comprises that further described protective seam passes through extrusion molding.
According to another one embodiment of the present utility model, the self-bearing type covered wire cable comprises that further described strengthening core adopts dacron to make.
According to another one embodiment of the present utility model, the self-bearing type covered wire cable comprises that further described strengthening core adopts metallic conductor to make.
According to another one embodiment of the present utility model, the self-bearing type covered wire cable comprises that further described metallic conductor is used for transmission of electric signals.
According to another one embodiment of the present utility model, the self-bearing type covered wire cable comprises that further described optical fiber is a naked fibre, or is single mode or multimode optical fiber.
According to another one embodiment of the present utility model, the self-bearing type covered wire cable comprises that further described stress buffer structure is a steel wire.
The beneficial effects of the utility model are: the utility model can bear than hightension and not damage optical fiber in the optical cable, and the utility model is simple in structure, and is easy to bifurcated, helps the connection of optical cable when entering the room the back application, installation and fixing.
