In the present embodiment, described pulley disc 108 centre of surface has the circular hole mated with erection column 107, and pulley disc 108 is rotationally connected with by this circular hole and is arranged on middle erection column 107.Concrete mounting means is, first installs the folding and unfolding fiber winding disk 300 of the bottom, is then enclosed within by pulley disc 108 on middle erection column 107, then installs the folding and unfolding fiber winding disk 300 of the second layer, by that analogy.Adopt such structure, the mounting structure of independent pulley disc 108 need not be set, simplify the structure.Weld portion 103 can be fixed by screws on this erection column 107 in addition, makes the utility model entirety more firm, has good practicality.
Described tail fiber disc stays on the outlet in portion 104 and is removably connected with some joint decks 105.Joint deck 105 can fix the position of tail optical fiber joint 201, convenient differentiation tail optical fiber 200.In the present embodiment, described joint deck 105 has 12, as preferably, described joint deck 105 is made up of two and half cards, described outlet is provided with some hole clippings 109 of mating with joint deck 105, two and half cards are stuck on tail optical fiber joint 201, and two and half cards are all inserted hole clipping 109 and can realize fixing, very convenient.Conveniently joint deck 105 adjustment direction, in the present embodiment, described hole clipping 109 is set to X-shaped, the direction of joint deck 105 can adjust according to the installation site of cell tray, if tail optical fiber joint 201 can be made downward in upper part, if according in lower part, tail optical fiber joint 201 can be made upwards.Second plate body front end face of described cover plate 101 is provided with 12 figure notations corresponding with 12 tail optical fiber joints 201, conveniently tail optical fiber 200 is numbered.
The tail fiber disc of the present embodiment stays the tail optical fiber coiled fashion in portion 104 as follows: install first group of folding and unfolding around the undermost folding and unfolding fiber winding disk 300 of fine structure, a tail optical fiber 200 is coiled on this folding and unfolding fiber winding disk 300, and after walking around pulley disc 108, tail optical fiber joint 201 is fixed into end by joint deck 105, then the folding and unfolding fiber winding disk 300 of the second layer is installed, by that analogy, until by three groups of folding and unfoldings around the whole installation of fine structure.
In the present embodiment, as preferably, the fine conduit 404 of the company of being provided with between described trunk optical fiber unit panel 402 and Distribution fibers unit panel 403, the tail optical fiber 200 in Distribution fibers unit panel 403 is connected to trunk optical fiber unit panel 402 through connecting fine conduit 404.
When the utility model uses, pulled out in Distribution fibers cell tray by tail optical fiber 200, directly link the connected adapter of trunk optical fiber cell tray, unnecessary tail optical fiber 200 still coils to be stayed in Distribution fibers cell tray.Compared with traditional connected mode, in fiber cable cross connection box, the connection of the optical fiber of each backbone optical cable and the optical fiber of optical distribution cable can save a double end jumping fiber and an adapter, any light path whole process that optical fiber between trunk and distribution is formed can reduce the attenuation of about 0.7dB, improves network quality.And the barrier point be connected to form decreased due to optical fiber and adapter.Simultaneously, after using optical fiber welding of the present utility model to join integrated unit dish, because the utility model can make tail optical fiber 200 pull out from folding and unfolding fiber winding disk 300, tail optical fiber 200 length that can use according to actual needs when block dish connects to trunk cell tray pulls out corresponding tail optical fiber 200, decrease the situation of tail optical fiber 200 redundancy in fiber cable cross connection box, make in fiber cable cross connection box, not need reserved tail fiber disc to stay district, also the tail optical fiber 200 in fiber cable cross connection box is made to arrange accordingly neat relatively in order, block dish can be arranged on the position that original tail fiber disc stays district, the position vacated can be used to increase backbone optical cable (or installing optical splitter), substantially increase the capacity of fiber cable cross connection box, such as: the most multipotency of former 288 fiber cable cross connection boxes opens 72 photosystems (for two fine photosystem), adopt fiber cable cross connection box of the present utility model can open 144 photosystems, capacity doubles, the various problems run into when avoiding existing fiber cable cross connection box dilatation, reduce dilatation difficulty and cost.In addition, because folding and unfolding is around the use of fine structure, the phenomenon making tail optical fiber 200 tail optical fiber 200 can not be caused to be pulled off in the process of pull-out, has good practicality.
The length computation mode of every root tail optical fiber 200 in Distribution fibers cell tray:
Transform example as with 288 core fiber cable cross connection boxes, the longest demand of tail optical fiber 200 to should be by bottom, Distribution fibers unit panel 403 to top, trunk optical fiber unit panel 402 (namely in Fig. 1, A to B locates) through connecting the distance of fine conduit 404, and computing formula is as follows:
L＝8u+h+d+w
Note: L: the length of tail optical fiber 200;
U: optical fiber welding joins integrated unit disc thickness, standard is 25mm;
H: the length connecting fine conduit 404, is not more than 2 times of optical fiber weldings and joins integrated unit dish length;
D: optical fiber welding joins integrated unit dish length, standard is 335mm;
W: the width connecting fine conduit 404, is designed to 60mm;
Calculate according to above formula, reserved tail optical fiber 200 maximum length is 1265mm, and in the present embodiment, reserved 1.5m, ensure that the safety that tail optical fiber 200 operates.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
