Abstract
The utility model relates to an improved indoor leading-in optical cable, particularly the construction of an optical cable. The utility model is characterized in that reinforcing elements are symmetrically arranged along both sides of an extension line of the diameter of optical fiber casing pipes; the number of the optical fiber casing pipes is not less than one; the section of an external sheath is of a prolate shape along the direction of the reinforcing element-the casing pipe-the reinforcing element or a rectangle or an oblate shape; the middle part of the longitudinal surface of the external sheath is provided with a groove pointing to the casing pipes. Because both of the two sides of the casing pipes are provided with the non-metallic reinforcing elements, not only the anti-side pressure of the optical cable can be increased, but also the defect of easy bending at the time of laying the cable can be overcome and the requirement of vertically and horizontally laying wires in a room can be satisfied. Secondly, because of the adoption of polyolefin materials, the fire retardant property and the lightning protection effect of the optical cable can be improved obviously. The utility model has the advantage of reasonable and simple structure, and is a beneficial and effective improvement.
Description
Technical field
The utility model relates to the structure of optical cable, especially a kind of improved indoor leading in cable.
Background technology
Inside cable also should be considered the actual needs of its aspect such as cloth cable under indoor vertical cloth cable and horizontal cloth cable and blanket except that possessing certain fire-retardant, tension, bending resistance and load-bearing property.But, indoor leading in cable in existing at present the use, internal structure from optical cable, adopt more in the cross section of circle the conventional structure that is made of outer protective sleeve, reinforcement and sleeve pipe be set---be that reinforcement has only one and be located at a side of sleeve pipe, optical fiber then is suspended among the ointment in the sleeve pipe.There is certain defective in the optical cable of this structure aspect counter-bending, resistance to compression, the integrated performance index such as fire-retardant and lightning-arrest, obviously not enough as performance index such as bending resistance, resistance to compressions, therefore therefore the needs of not exclusively suitable indoor leading in cable, await further improvement and perfect.
The utility model content
The purpose of this utility model, it is the deficiency that exists in the existing cable configuration for overcoming, and a kind of improved indoor leading in cable is proposed, for realizing that this purpose adopts following technical scheme: a kind of improved indoor leading in cable, comprise outer protective sleeve, sleeve pipe, optical fiber and reinforcement, it is characterized in that the monosymmetric reinforcement that is provided with along the casing diameter extended line, the number of ferrule is no less than 1, the section of outer protective sleeve be one along reinforcement the prolate shape of---sleeve pipe---reinforcement direction, the section of outer protective sleeve is a rectangle, and the section of outer protective sleeve is oblate; The vertical surface of outer protective sleeve is provided with the groove that points to sleeve pipe.
Press the optical cable that this programme is implemented,, not only improved the lateral pressure resistant power of optical cable owing to be provided with the reinforcement of nonmetal system in the sleeve pipe both sides, and the defective of bending easily when having overcome the cloth cable, satisfied the indoor requirement of wiring in length and breadth.Secondly, also because of adopting polyolefine material more significantly to improve the fire resistance and the lightning-arrest effect of optical cable.Of the present utility model rational in infrastructure, simple and direct, be a kind of useful and effective improvement.
Description of drawings
Fig. 1 is the section structure synoptic diagram of a kind of embodiment of the utility model;
Fig. 2 is the section structure synoptic diagram of another kind of embodiment.
Embodiment
Be further described in detail with regard to a kind of embodiment in conjunction with the accompanying drawings.The section of sheath 1 is a rectangle, its sleeve pipe 3 that is built-in with optical fiber 4 places the center of sheath 1, the reinforcement 2 of two nonmetal systems is set along the both sides of long line at sleeve pipe 3 diameters, this non-metal reinforcement member has bending resistance preferably and compressive property, guarantees for the smooth wiring of inside cable provides good material.Be shaped on " V " shape groove 5 that points to sleeve pipe 3 along sheath 1 vertical surface, the effect of this groove 5 is to be beneficial to the butt joint construction of optical cable for strip off sheath 1 easily.Therewith in like manner, can be shaped on the optical cable of 2 above ferrules according to actual needs, for example, be shaped on 2 ferrules in the sheath, then the number of reinforcement is 3, and " V " shape groove 5 of jacket surface all is equal to the number of the light sleeve pipe of its sensing.
The section that another kind of embodiment of the present utility model is a sheath 1 is made oblateness (Fig. 2), for adapting to some high capacity transmission requirements, be provided with 2 sleeve pipes 3 that contain optical fiber 4 in this sheath 1, in the both sides of sleeve pipe 33 non-metal reinforcement members 2 are set respectively, we can say, when 2 above ferrules were set in the sheath 1, the number that is provided with of its reinforcement was (n+1), and n is the number of ferrule.The sheath both sides are that oblate section has slyness, characteristics attractive in appearance, are of value to the coordination of house wiring.
Claims (4)
1, a kind of improved indoor leading in cable, comprise outer protective sleeve, ferrule and reinforcement, it is characterized in that the monosymmetric reinforcement that is provided with along ferrule diameter extended line, the number of ferrule is no less than 1, the section of outer protective sleeve be one along reinforcement the prolate shape of---sleeve pipe---reinforcement direction.
2, by the described improved indoor leading in cable of claim 1, the section that it is characterized in that outer protective sleeve is a rectangle.
3, by the described improved indoor leading in cable of claim 1, the section that it is characterized in that outer protective sleeve is for oblate.
4,, it is characterized in that the vertical surface of outer protective sleeve is provided with the groove that points to sleeve pipe by claim 1,2 or 3 described improved indoor leading in cables.
