Description

Rotary fibre distribution frame

Technical field

The utility model relates to a kind of fibre distribution frame.

Background technology

In original communication network; Optical fiber is main with relay transmission; Bear between the local side or local side and node between optical communication transmission, two-end-point is light requirement electrical signal conversion equipment respectively, and local side is to transmit through category-5 cable or copper twisted pairs to user side; Form the communications network, realize the function of voice communication and ADSL Internet connection.And cable commonly used is because its decay is big in the transmission in the past, and volume is big, Heavy Weight, a large amount of non-ferrous metals of consumption, construction transportation inconvenience and frequency capability is little, transfer rate is slow and problem such as anti-tampering property difference, can't satisfy the requirement of user's high definition television equiband.

Development along with high-bandwidth information communication unification of three nets (audio frequency, internet, DTV) growth of requirement and passive optical network technique Fibre Optical Communication Technologies such as (PON); Fiber bandwidth height, distance, advantage such as cheap will further manifest, and optical fiber is used widely and is progressively replaced the inexorable trend that copper cable will become development at Access Layer.Insert the network construction characteristic of " high capacity, an institute of few office, the wide covering " to optical fiber, originally be transmitted as main development and the production organizational mode of the Access Layer optical fiber physical network that comes can not adapt to the development of scale optical fiber access service by Optical fiber relay.

Fibre distribution frame is the visual plant in the optical network system, is used to accomplish optical cable and introduces, fixes, opens stripping protection, fused fiber splice and protection, tail optical fiber storage, jumping fiber storage and management, optical fiber fixed connection and cross connection etc.The general optical fiber distributing frame comprises support body and is located at the block on the support body; But general block all is fixed on the support body usually; Relocate if desired or keep in repair, need user's direct control or block taken off the back operation on support body, operation is inconvenience very.

Summary of the invention

The utility model technical matters to be solved provides a kind of rotary fibre distribution frame that can the block rotation be taken out of person easy to use operation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of rotary fibre distribution frame; Comprise support body and be fixed in the block on the support body; It is characterized in that: said block comprises the box body that is fixed in the housing on the support body and is positioned at housing; Said housing comprise be positioned at about and rear side be support that framework is provided with and horizontally disposed in the flat board of support above and below; One end of the front side of the bottom of said box body have one with the hinge of the bottom vertical of said box body, box body is connected with the flat board of distributing frame, and the box body of this block can rotate around this hinge in the plane parallel with flat board.

Preferably, have on the said support this block is fixed in a plurality of screws on the support body.

For the ease of stretching out of the tail optical fiber in the box body, have opening on the support of said housing rear side, the rear side of said box body has perforate.

Preferably, the front side width of said box body is less than back side width.

Rotation for the ease of box body stretches out in housing, the front side of said box body with respect to the other end of this hinge have one protrude in this box body handle.

Compared with prior art, the advantage of the utility model is this rotary fibre distribution frame, and the box body in the block can rotate around hinge and stretch out in housing, makes things convenient for connection and the welding of the optical fiber in the box body etc., is convenient to operate.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

The distributing frame of the utility model; Comprise the support body (not shown) and be positioned at theblock 1 on the support body;Block 1 compriseshousing 12, is positioned at thebox body 11 ofhousing 12;Housing 12 comprise be positioned at about and rear side be support 121 that framework is provided with and horizontally disposed in theflat board 122 ofsupport 121 above and belows, have a plurality of screws on thesupport 121 and be used forblock 1 is fixed in support body.

Have opening 123 on thesupport 121 ofhousing 12 rear sides, the rear side of saidbox body 11 also has perforate 111, and this perforate 111 passes with the tail optical fiber that opening 123 is used in the box body 11.Have a plurality of joints ofoptical fibre 13 on the front panel ofbox body 11 and be used for the access of optical fiber, be equipped with parts such as welding, beam split in thebox body 11.

One end of the front side of the bottom of thebox body 11 of thisblock 1; Have one with the bottom vertical ofbox body 11, the i.e. hinge 2 vertical with dull and stereotyped 122;Box body 11 is connected with theflat board 122 of below; Thebox body 11 of thisblock 1 can be rotated in the plane parallel with dull and stereotyped 122 around thishinge 2; Therefore thisbox body 11 can rotate the space that housing 12 is surrounded aroundhinge 2, and the top vacancy of thisbox body 11, whenbox body 11 rotateshousing 12, just can operate fused fiber splice or light-dividing device in this box body 11.Rotation for the ease of thebox body 11 of thisblock 1 is stretched out, the front side of the bottom of thisbox body 11 with respect to the other end of thishinge 2 also have one protrude in the panel of thisbox body 11 handle 3.And, thisbox body 11 be shaped as back side width less than the front side width, like Fig. 2, shown in 3, for the front side of thisbox body 11 to rear side, width dwindles gradually.

Box body 11 in this rotary fibre distribution frame,block 1 can rotate around hinge and stretch out inhousing 12, makes things convenient for connection and the welding of the optical fiber in thebox body 11 etc., is convenient to operate.

Except that the foregoing description, the utility model also includes other embodiments, and the technical scheme that all employing equivalents or equivalent substitute mode form all should fall within the protection domain of the utility model claim.
