Abstract
The utility model relates to an optical cable branch service entrance joint box, which is suitable for leading optical fibers into a room. The utility model comprises a box body, both sides of the box body are provided with optical cable inlets and outlets and cable fixing devices, and an optical fiber ribbon fan-out tail fiber receptacle is arranged in the box body. The optical fiber ribbon fan-out tail fiber receptacle comprises an optical fiber ribbon receptacle and a tail fiber receptacle. The utility model has the advantages that the optical cable branch service entrance joint box is especially suitable for carrying out branching and fiber laying for leading optical fibers into a room to a skeleton-type optical fiber ribbon optical cable, and cable fixing and fibers division are very convenient; the skeleton-type optical fiber ribbon optical cable is adopted, the branching point of the optical cable is provided with a branching window, optical fiber ribbons are separated and switched into tail fibers from the branching window and enter into a room, and the method for laying cables and fibers can reach the purposes of little consumption of cables, easy branching of the optical cable and easy construction; the utility model also has the advantages of simple structure and convenient installation and use, the laying cost for leading optical fibers into a room can be reduced and the utility model is favorable for the implementation and popularization for leading optical fibers into a room.
Description
Technical field
The utility model relates to a kind of optical cable difference house lead in connector box of using during Fiber to the home of being suitable for, and uses when it is particularly suitable for slotted core fiber ribbon cable difference house lead in.
Background technology
Along with the develop rapidly of the communication technology and industry, the transmission of optical fiber has begun therefrom long Distance Transmission progressively to short-range fiber-to-the-home direction expansion.Existing fiber mostly adopts tight sleeve optic cable and common loose jacket layer strand optical cable to the fiber cable laying cloth method for fiber at family, when needs difference house lead in optical fiber, can only cut off that optical cable continues or lay simultaneously and tap into many optical cables because of starting separator window, so not only the amount of expending of optical cable is big, the pipeline space that takies when laying is big, and a large amount of cables are crowded, difference continues very loaded down with trivial details, and the factice for filling in tight sleeve optic cable and the common loose jacket layer strand optical cable also brings very big inconvenience to construction.
Adopt slotted core fiber ribbon cable, offer the difference window at the parting of optical cable, from the cable core of difference window, take out the fibre ribbon of drawing difference, tail optical fiber is transferred in the fibre ribbon separation enter the deficiency that indoor cabling cloth method for fiber can overcome above-mentioned existence preferably, it is few to reach cable consumption, optical cable is easy to difference, easy construction, the purpose that laid down cost is low.For finishing the fine task of above-mentioned difference cloth, need divide fine connector box at the solid cable of parting configuration.But existing connector box can not be suitable for slotted core fiber ribbon cable carries out fiber-to-the-home difference cloth fibre.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of optical cable difference house lead in connector box that is suitable for use in Fiber to the home, it has characteristics simple in structure, as to be convenient to the difference installation, is particularly suitable for using when the difference house lead in of slotted core fiber ribbon cable.
The utility model is that the technical scheme that technical matters adopted of the above-mentioned proposition of solution is: include box body 7, the box body both sides are provided with optical cable import and export and the solid cable device 8 of configuration, are provided with fibre ribbon fan-out tail optical fiber storing tray in the box body.
Press such scheme, described fibre ribbon fan-out tail optical fiber storing tray comprises fibre ribbon storing tray 9 and tail optical fiber storing tray 3; Described fibre ribbon storing tray includes an oval shape or oval-shaped disk body, and the corresponding solid cable device of a side of disk body is offered into fine mouthful; Described tail optical fiber storing tray includes an oval shape or oval-shaped disk body, and the corresponding fibre ribbon storing tray of a side of disk body is offered into fine mouthful 5, offers fiber mouth 12 in the side direction of disk body; The minimum bending radius of fibre ribbon storing tray and tail optical fiber storing tray rim is superimposed up and down greater than 37.5mm fibre ribbon storing tray and tail optical fiber storing tray, is bonded with each other by hinge 10 or hasp.
When the utility model uses with slotted core fiber ribbon cable 1 advancing from box body, outlet is passed, the difference window 4 of slotted core fiber ribbon cable is stayed in the box, by solid cable device optical cable difference window both sides are fixed, to need the fibre ribbon of difference to cut off from the difference window by the window of difference the preceding that extends forward, take out the fibre ribbon 6 of drawing a segment length from the difference window and introduce the fibre ribbon storing tray as the difference optical fiber that continues, fibre ribbon enters the tail optical fiber storing tray after holding a segment length in dish, in dish, be separated into single tail optical fiber 11, each tail optical fiber is drawn by fiber mouth 12 after holding a segment length in dish, and the difference that can finish optical fiber continues.
The beneficial effects of the utility model are: 1, be particularly suitable for slotted core fiber ribbon cable is carried out fiber-to-the-home difference cloth fibre, Gu cable divides fibre very easy; And the employing slotted core fiber ribbon cable, offer the difference window at the parting of optical cable, from the difference window fibre ribbon is separated and to transfer into tail optical fiber and enter indoor cabling cloth method for fiber can to reach cable consumption few, optical cable is easy to difference, the purpose 2 of easy construction, simple in structure, easy to install, fiber-to-the-home laid down cost is reduced, help fiber-to-the-home enforcement and popularization.
