Abstract
The utility model discloses an optical cable which comprises a sheath and supporting bodies arranged on both sides inside the sheath. An optical fiber is arranged at the middle part of the sheath, a grooving is arranged on the outer surface of the sheath, and is positioned on the perpendicular bisector of the two supporting bodies, the sheath is rectangular, the grooving presents a square shape or a circular arc shape, the sheath is made of flame retardant polyethylene plastic, and the supporting bodies are made of stainless steel wires. The cross section of the sheath in the optical cable is rectangular; compared with a sheath with a round cross section, the consumption of materials is reduced, thereby the production cost is reduced; the symmetrical supporting bodies are arranged on both sides of the grooving of the upper and the lower surfaces simultaneously; and when the optical cable is sectioned, the two supporting bodies are undrawn outwards, so that the sheath not only can be sectioned along the grooving, thereby exposing the optical fiber, and simplifying the section line, but also can be sectioned by adopting a section line pincher. The optical cable is formed in one step, and has convenient manufacture.
Description
Technical field
The utility model relates to a kind of optical cable that is used for fiber-to-the-home Network Transmission.
Background technology
Along with development of Communication Technique; the application of optical cable is increasingly extensive; common optical cable has pipe core bundle cable, layer-stranding cable and slotted core cable at present; because optical fiber is made by silicon dioxide; silicon dioxide is the extremely crisp material of no ductility; therefore optical fiber need be placed in tight sleeve pipe, loose sleeve pipe or the skeleton grooves and protect, thus the performance of assurance optical cable.Such cable configuration has the following disadvantages: pipe core bundle cable manufacturing process complexity, and volume is big, and its xsect adopts circular, makes material usage big, the production cost height, round section is unfavorable for the hatching line of optical cable simultaneously.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of optical cable, can effectively solve existing optical cable hatching line inconvenience and sheath material consumption and cause the high problem of production cost greatly.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of optical cable, comprise sheath and the supporter that is located at the inner both sides of sheath, and the sheath middle part is provided with optical fiber, it is characterized in that: jacket outer surface is provided with grooving, and grooving is positioned on the perpendicular bisector of two supporters.
Further, jacket outer surface is equipped with grooving on the perpendicular bisector of two supporters, and is very easy when making the optical cable hatching line.
Further, sheath is a rectangular parallelepiped.
Further, grooving is square.
Further, grooving is circular arc.
Further, sheath adopts flame-retardant polyethylene plastic to make, and makes optical cable corrosion-resistant, prolongs the serviceable life of optical cable.
Further, supporter adopts the stainless steel steel wire, and supporter itself can not get rusty, and can improve the tensile strength of optical cable again, and optical fiber is shielded.
The utility model is owing to adopted technique scheme, and the xsect of sheath adopts rectangle, has reduced the consumption of material with respect to the sheath of existing circular cross section, has reduced production cost; The grooving both sides of upper and lower surface are provided with the symmetric support body simultaneously, during the optical cable hatching line, two supporters are outwards drawn back separately, sheath promptly can be cut open along grooving, exposes optical fiber, and hatching line is easy, can certainly adopt the hatching line pincers to carry out hatching line, and the utility model one-shot forming, easily manufactured.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of a kind of optical cable of the utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is circular-arc structural representation for grooving in the utility model.
Embodiment
As shown in Figure 1 to Figure 3, for a kind of optical cable of the utility model, comprise sheath 1, sheath 1 adopts flame-retardant polyethylene plastic to make, sheath 1 is a rectangular parallelepiped, be provided with the middle part that two optical fiber 2 and 3, two optical fiber 2 of two supporters are located at sheath 1 in the sheath 1, two supporters 3 are located at the both sides of sheath 1, sheath 1 outside surface is provided with grooving 4, grooving 4 is positioned on the perpendicular bisector of two supporters 3, and grooving 4 can be square or circular arc, makes sheath 1 be the horizontal figure of eight.The xsect of sheath 1 adopts rectangle, is circular with respect to existing sheath xsect, has reduced the consumption of sheath 1 material, has reduced production cost; When the optical cable hatching line, two supporters 3 are outwards drawn back separately simultaneously, sheath 1 promptly can be cut open along grooving 4, exposes optical fiber 2, and hatching line is easy, can certainly adopt the hatching line pincers to carry out hatching line.
