Description

The intensification fiber box

The utility model relates to a kind of Cheng Duan of optical fiber telecommunications system local side backbone optical cable and intensification fiber box of distribution of being used for.

The existing fiber box (referring to Fig. 4) that is used for fibre distribution frame, the a plurality of optical fiber end blocks that are arranged above and below wherein be about equidistant symmetry be installed in the distributing cabinet, also promptly after optical fiber end block is installed on the centre position of fiber box, the disk body dual-side is identical with the space length on casing both sides, and this structure is unfavorable for installation (continue, the distribution) operation of optical fiber distributing.Because, optical fiber end block is installed on the centre position of fiber box, make the operating space between module and the casing be divided into two, cause the space length on both sides in the case all limited.And the inevitable inconvenience of the installation of in limited space, carrying out optical fiber distributing.And because the spatial accommodation on both sides is limited in the case, fiber bending radius is less.Also be, when fibre junction, distribution and assembly are installed, need move when extracting module out, make optical fiber form the less kink of a radius-of-curvature inevitably at the connecting portion of module and distributing cabinet, not only easily affect optical fiber, influence the insertion loss of whole optical fiber, and kink wound also easy to break is impaired, causes unsafe hidden danger.

The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of intensive chemical fibre distributing cabinet of the light of bigger operating space in the fiber box that provides is provided, it can carry out the installation of various optical fiber up and down according to user's different needs in fiber box, and can prolong product serviceable life, thereby improve safety in utilization.The fine storage of its light harvesting, welding, distribution, wire jumper and distribution function are one, can change configuration flexibly, are suitable for the continuing of various optical cables, distribution and installation.

For achieving the above object, the utility model provides a kind of intensification fiber box, it comprises: a tank tower and be connected in some terminal modules on this tank tower, described tank tower comprises a casing and forward and backward chamber door, described chamber door detached type respectively is arranged at forward and backward of casing, also is provided with some seton devices on the casing; Described a plurality of terminal module is connected in the casing up and down by coupling shaft in regular turn, be characterized in: described each terminal module is a left and right symmetrical part, both sides at its nearly straight flange offer forward and backward line outlet respectively, and offer the axial trough of ccontaining coupling shaft between preceding line outlet and back line outlet; Be provided with a coupling shaft in the described casing, the side that axial trough and the coupling shaft of described terminal module by the one side is connected in casing rotationally.

The utility model is owing to increased the axial trough of ccontaining coupling shaft between forward and backward line outlet in the both sides of terminal module, axial trough by this wherein any side terminal module can be connected in casing about on the coupling shaft of any side, basic like this from having changed the symmetrical Installation Modes of prior art.This asymmetric Installation Modes can increase the channel distance between disk body one side and the mould bases, thereby operating space bigger in the fiber box can be provided.When the operation that cable connection, distribution and assembly are installed, only need rotating module just can make it to screw out distributing cabinet.When the optical fiber distributing mould is installed in the fiber box,, and can in casing, connect up because optical fiber can be placed through up and down between the module.Like this, because of needn't detouring, optical fiber can reduce fiber lengths outside casing.So, the kink radius-of-curvature that the connecting portion of optical fiber between module forms is bigger, and rotation is flexible and kink wound not easy to break is impaired, safe in utilization.

The utility model is described in further detail below in conjunction with embodiment that accompanying drawing and accompanying drawing provide:

Fig. 1 is a front view of the present utility model;

Fig. 2 is the plan structure synoptic diagram of Fig. 1;

Fig. 3 is the structural representation of terminal module in the utility model;

Fig. 4 is the structural representation of prior art;

Fig. 5 is the left-handed user mode figure that opens of the present utility model;

Fig. 6 is installed on user mode figure in the optical fiber patch bay for the utility model.

At first referring to Fig. 1,2, a kind of 19 inches standard sizes intensification fiber box, it comprises: a cabinet type tank tower 10 and the some terminal modules 20 on this tank tower of being coupling, a plurality of terminal modules 20 are connected in the casing 11 up and down in regular turn by the vertical pivot on the casing 11.This tank tower 10 comprises a casing 11 and forward and backward chamber door 12,13, and the front and back chamber door is that detached type is installed on forward and backward of casing 11 respectively; Also be provided with some seton devices 14 on the casing.In addition, push up on casing (11) one sides and go to the bottom between be provided with a coupling shaft 15, in casing 11, the opposite side corresponding with coupling shaft 15 also is provided with a lock shaft 17; Also be provided with a locating shaft 16 at nearly coupling shaft 15 places, coupling shaft 15 and locating shaft 16 can be located at casing (11) left side or right side, and coupling shaft 15 and locating shaft 16 are located in the casing 11 and are advisable apart from left side wall or the about 60mm of right side wall place.

Referring to Fig. 3, module 20 is made by the ABS flame-proofed polymer material is one-body molded, each is provided with a plurality of catch above the module, two take-up rings, before two flange plate decks and some operation preformed holes (not shown label) and two,

back line outlet

21,22, they are opened in the both sides near module 20 straight flanges respectively, and between preceding line outlet 21 and back line outlet 22, offer the axial trough 23 of ccontaining coupling shaft, also be provided with a clamping block 24 in the notch lower end of this axial trough 23, terminal module 20 is connected in a side in the casing 11 rotationally by the axial trough 23 and the coupling shaft 15 of one side.Because the disk body symmetria bilateralis offers forward and backward

line outlet

21,22 and axial trough 23, like this, terminal module 20 can be connected in the left side or the right side of casing 11 arbitrarily by arbitrary axial trough recess 23 wherein, and reserves the passage 26 (simultaneously referring to Fig. 1,2) for operation, and this passage is generally 60mm.

Referring to Fig. 5, when the axial trough 23 of module 20 coupling shaft by fiber box one side is connected in the left side of distributing cabinet, just can makes module 20 around coupling shaft 15 rotations, and when connecing distribution, can easily module be rotated distributing cabinet; When it rotates to 90 when spending, then can give position and lock by the lock shaft 17 of being located in the casing opposite side corresponding with coupling shaft 15; When the module return is closed, but clamping block 24 just trip on distributing cabinet lock shaft 17 and locate.

The width of the utility model optical fiber end block 20 is littler than general optical fiber end block, can be between 350-390mm, be good generally with 360mm (being the length of straight flange 25), when it is placed in a side of standard-sized 19 inches fiber box 20, can in distributing cabinet, reserves more major path 26 and be convenient to operation.
