A kind of fiber cable cross connection box comprises casing, base, frame assembly, and described casing is fixed on the base, frame assembly is fixed in the casing, the first line of a couplet of described casing is equiped with molten unit and the fine storage unit of Sheng of joining of optical cable, and the second line of a couplet of casing is equiped with straight-through unit of optical fiber and optical cable fixing device

Described optical cable is molten joins the unit and comprises a plurality of welding distribution integrated modules in order to mounting adapter, all around being provided with of described frame assembly is a plurality of in order to the guide rail support plate of described welding distribution integrated module and/or light shunt module to be installed, and described welding distribution integrated module is stacked on the described guide rail support plate from top to bottom.

Wherein, described welding distribution integrated module comprises cover plate, welding holder, fusion joining disk, distribution board, the fine plate of mistake of closed assembly successively.

Wherein, described optical cable is molten joins the unit and comprises 96 welding distribution integrated modules, and is provided with 12 adapters on each welding distribution integrated module.

Wherein, described casing is front and back four door casings, and described welding distribution integrated module is installed on respectively on the guide rail support plate all around of frame assembly.

The beneficial effects of the utility model are:

On the utility model middle frame assembly welding distribution integrated module and light shunt module can be installed simultaneously, thereby possessed the integrated and light of welding distribution ability along separate routes simultaneously, not only increased capacity greatly, improved the quality of connection of optical fiber in fiber cable cross connection box, and avoided room of independent use that the Cheng Duan of light shunt module and optical cable is set, what greatly reduce the light shunt module is provided with difficulty and cost.

Description of drawings

The invention will be further described below in conjunction with drawings and Examples, in the accompanying drawing:

Fig. 1 is the structural representation of the utility model fiber cable cross connection box;

Fig. 2 is the structural representation of the welding distribution integrated module of the utility model fiber cable cross connection box;

Fig. 3 is the structural representation of the light shunt module of the utility model fiber cable cross connection box.

Wherein, 01-cabling conduit, 02-frame assembly, 03-base, the 04-door, 05-casing, 10-are contained fine storage unit, and 11-is around fine post, the 20-optical cable fixing device, 21-optical cable, 22-jumping fiber, 30-optical fiber leads directly to the unit, 40-light shunt module, 50-welding distribution integrated module, the 60-optical cable is molten joins the unit, 80-distribution board, 81-fusion joining disk, 82-welding holder, 83-crosses fine plate, the 84-cover plate.

Embodiment

As shown in Figure 1 to Figure 3, fiber cable cross connection box provided by the utility model is made of four door casing 05, frame assembly 02 and the base 03 of macromolecular material die forming, the casing 05 inner first line of a couplet is provided with molten unit 30 and the fine storage unit 10 of Sheng of joining of optical cable, and the casing 05 inner second line of a couplet is provided with straight-through unit 30 of optical fiber and optical cable fixing device 20;

And arranged on left and right sides in the casing all is equipped with the casing joint cover, frame assembly 02, the straight-through unit 30 of optical fiber and the bottom of optical cable fixing device 20 in joint cover is separately fixed at casing 05;

Frame assembly 02 is by left and right pillar, lower and upper cross-member, is formed by connecting by screw around fine post 11, guide rail support plate, cabling conduit 01, and its left-right and front-back is respectively arranged with the molten unit 60 of joining of optical cable;

Optical cable is molten joins unit 60 and comprises a plurality of welding distribution integrated modules 50, welding distribution integrated module 50 is stacked on the guide rail support plate of frame assembly 02 from top to bottom, can extract out to carry out welding and distribution along guide rail respectively, this welding distribution integrated module is made up of distribution board 80, fusion joining disk 81, welding holder 82, cover plate 84, the fine plate 83 of mistake.

In the present embodiment, the molten unit 30 of joining of the optical cable of all around being installed of frame assembly 02 comprises 96 row's welding distribution integrated modules 50 altogether; And each welding distribution integrated module 50 can install and fix 12 optical adapters, distribution board is around 12 patch cords, welding is simultaneously also taken inventory 12 optical fiber, make that like this capacity obviously increases, and because cabling uses vertical trough and horizontal trough jumping fiber management system, jumping fiber route clear and definite, circuit is searched efficient and convenient.

In addition, in above-mentioned casing, can reduce the installation quantity of welding distribution integrated module 50, and with this installation position being installed by light shunt module 40, light shunt module 40 and welding distribution integrated module 50 physical dimension and installation dimension compatibility, smooth shunt module took welding distribution integrated module 50 installation positions in 1 minute 16, and smooth shunt module took two welding distribution integrated module 50 installation positions in 1 minute 32, and smooth shunt module took four welding distribution integrated module 50 installation positions in 1 minute 64; So as need dress light shunt module, the installation site that only need take some weldings distribution integrated module 50 gets final product.

The principle of work of above-mentioned fiber cable cross connection box is: be provided with the installation position of welding distribution integrated module 50 and light shunt module 40 in the casing 05, therefore possess the integrated and light shunt ability of welding distribution.Be specially: backbone optical cable enters casing 05 through optical cable fixing device 20, becomes end after opening stripping on the adapter of welding distribution integrated module 50; Second line of a couplet optical distribution cable or residence network optical cable enter casing 05 through optical cable fixing device 20, in straight-through unit 30 weldings of the optical fiber of the second line of a couplet, form forthright after opening stripping; The quantity of light shunt module 40 can dispose as required, and the tail optical fiber of going into to hold of welding distribution and light shunt module connects or jumper connection with the adapter of welding distribution integrated module and light shunt module dish.Containing when fine when optical fiber can storing around fine post about the first line of a couplet, therefore connect or jumper connection flexible dispatching more, but particularly because the quantity flexible configuration of light shunt module, avoided room of independent usefulness that the Cheng Duan of light shunt module and optical cable is set, what greatly reduce the light shunt module is provided with difficulty and cost.

Above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, only with reference to preferred embodiment the utility model is had been described in detail.Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical solution of the utility model, and do not break away from the spirit and scope of technical solutions of the utility model, all should be encompassed in the middle of the claim scope of the present utility model.
