Description
Technical field
The utility model relates to a kind of communication component, specifically a kind of self-support cable.
Background technology
Volume is little, cost is low owing to having for butterfly optical cable, good bending property and lay the advantages such as convenient, obtains and apply widely in Intelligent Building, digital cells, campus network and LAN (Local Area Network).But the internal placement of existing butterfly optical cable has two optical fiber, the fibre-optical splice be arranged on butterfly optical cable but can only connect a wherein optical fiber, and another optical fiber connects difficulty and cannot use and cause idle greatly, creates unnecessary waste; Meanwhile, usually need to lay the wirerope being used for bulit on stilts before outdoor mounted butterfly optical cable, installation process is comparatively loaded down with trivial details.
Utility model content
The purpose of this utility model overcomes the deficiency in above-mentioned background technology, and provide a kind of self-bearing type two butterfly optical cable, this optical cable should have the feature that fiber utilization is high, easy for installation and tensile strength is good, without the need to laying steel wire in addition during outdoor mounted.
The technical solution of the utility model is: the two butterfly optical cable of self-bearing type, is characterized in that: this optical cable comprises a self-supporting line and is arranged in parallel in the butterfly optical cable of self-supporting line both sides; Be connected as a single entity by the connecting portion being easy to tear off between the oversheath of described self-supporting line and the sheath of butterfly optical cable;
A self-supporting steel wire or steel strand wires are furnished with in the oversheath of described self-supporting line; Be furnished with an optical fiber in the sheath of described butterfly optical cable and be positioned at two reinforcements of optical fiber both sides, and sheath two sides is respectively shaped with the groove that an axial extension is beneficial to ripping sheath.
Described reinforcement is steel wire or FRP reinforcement.
The thickness of described connecting portion is 1-3mm.
Described sheath and oversheath all adopt low-smoke halogen-free flame retardant material.
Described steel wire and self-supporting steel wire all adopt phosphating steel wire.
The beneficial effects of the utility model are:
Be furnished with an optical fiber in every bar butterfly optical cable in the utility model to make two butterfly optical cables all can install existing fibre-optical splice, thus improve the utilization factor of optical fiber, install also very convenient; And the utility model is also provided with one for carrying high-tensile self-supporting line, when outdoor mounted without the need to laying steel wire in advance, thus simplifying installation process, improve installation effectiveness.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model xsect.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in Figure 1, the two butterfly optical cable of self-bearing type, comprises a self-supporting line and two butterfly optical cables.
Described self-supporting line comprises a self-supporting steel wire 21 (or steel strand wires) and is wrapped in the oversheath 22 of self-supporting steel wire outside; Described self-supporting steel wire is phosphating steel wire and oversheath adopts low-smoke halogen-free flame retardant material; This self-supporting line effectively can improve the tensile strength of the two butterfly optical cable of self-bearing type.
Described every bar butterfly optical cable comprises the optical fiber 11 and two reinforcements 13 that extend in the same way and the sheath 12 being wrapped in optical fiber and reinforcement outside; Described fiber arrangement is in the center of sheath, and reinforcement is then arranged in the both sides (left and right directions in figure) of optical fiber; Described reinforcement is steel wire (preferred phosphating steel wire) or FRP (aramid fiber) reinforcement and sheath adopts low-smoke halogen-free flame retardant material.
The sheath of every bar butterfly optical cable is a ribbon ennation, and the two sides (upper and lower surface in figure) of sheath is respectively shaped with one and extends the groove 14 being beneficial to ripping sheath in the longitudinal direction; Exerted oneself with different directions in the sheath both sides (both sides of side groove) of butterfly optical cable, the line direction of lower notches (in figure shown in A) just can be forced to occur rupture and be separated both sides sheath, thus separate the optical fiber being positioned at sheath center.
The structure of described butterfly optical cable is similar to the structure of existing butterfly optical cable, therefore can install existing fibre-optical splice easily; Its difference part is only the utilization factor into improving optical fiber, and avoid causing unnecessary waste, an optical fiber is only arranged in the inside of butterfly optical cable.
Described self-supporting line and butterfly optical cable extend in the same way and two butterfly optical cables are arranged in the both sides of self-supporting line.Be connected as a single entity by connecting portion 3 between the oversheath of described self-supporting line and the sheath of butterfly optical cable; The thickness of this connecting portion is generally 1-3mm, is less than the thickness of butterfly optical cable, so just can reduce the structural strength of connecting portion, and when being subject to external force and pullling, connecting portion can break at first, the stripping of self-supporting line when ensureing to install; When pinching two butterfly optical cables and to both sides tearing, the length direction of connecting portion ruptures, butterfly optical cable and self-supporting line disconnected from each other.
Claims (5)
1. the two butterfly optical cable of self-bearing type, is characterized in that: this optical cable comprises a self-supporting line and is arranged in parallel in the butterfly optical cable of self-supporting line both sides; Connecting portion (3) by being easy to tear off between the oversheath (22) of described self-supporting line and the sheath (12) of butterfly optical cable is connected as a single entity;
A self-supporting steel wire (21) or steel strand wires are furnished with in the oversheath of described self-supporting line; Be furnished with an optical fiber (11) in the sheath of described butterfly optical cable and be positioned at two reinforcements (23) of optical fiber both sides, and sheath two sides is respectively shaped with the groove (14) that an axial extension is beneficial to ripping sheath.
2. the two butterfly optical cable of self-bearing type according to claim 1, is characterized in that: described reinforcement is steel wire or FRP reinforcement.
