Abstract

The invention discloses a fiber storing type optical fiber distribution box used for a 19-inch cabinet. The optical fiber distribution box is structurally composed of an upper cover, a tray, a guide rail and a wiring trough. The tray is installed in the upper cover through the guide rail, a tail optical fiber body, with a certain length, of an optical fiber can be stored in the tray, the tail optical fiber body is wound on a winding post in the tray with four cores as a set, and meanwhile space for tail optical fiber body splicing and space for pre-terminated optical fiber winding are reserved in the tray. The optical fiber distribution box has the advantages that space in the optical fiber distribution box is fully used, the tail optical fiber body of the certain length can be stored on the premise that the bending radius of the optical fiber is met, and the tail optical fiber body can be used for being directly connected with another device; when the fiber storing type optical fiber distribution box is used, an optical fiber patch cord is not needed for being connected with another device, so that a movable connection point is reduced when the fiber storing type optical fiber distribution box is used, and loss of an optical fiber link is reduced; the optical fiber of the tray is movably connected with a parking space and is compatible with a standard optical fiber, and a standard optical fiber adapter can be installed.

Description

Fiber storage type fibre distribution box for 19 inches of racks

Technical field

The present invention relates to a kind of fiber storage type fibre distribution box for 19 inches of racks, belong to optical fiber splicing device skill Art field.

Background technology

At present, with the raising of rack inner fiber density, need in increasing rack substantial amounts of fiber storage unit is installed, Thus by limited space hold in rack, the space of rack is made to lift very little；Presence is used for fibre distribution box Following point: 1, fibre distribution box is served only for into end it is impossible to long more than storage wire jumper manage wire jumper it is impossible to arrange；2nd, optical fiber fiber storage Box can only store length more than wire jumper；3rd, using needing wire jumper to connect, each connection needs to produce two flexible connections fibre distribution box Point, increased link load.

Content of the invention

Proposed by the present invention is a kind of fiber storage type fibre distribution box for 19 inches of racks, and its purpose is intended to overcome existing Drawbacks described above existing for technology, by limited cabinet space by the way of combining fibre distribution box with optical fiber fiber storage box All of getting up, both can reduce link load, and be also convenient for wire jumper management, truly increased the close of single rack Degree.

The technical solution of the present invention: a kind of fiber storage type fibre distribution box for 19 inches of racks, its structure is bag Include lid, pallet, fusion joining disk, wrapping post, parking stall, optical fiber pigtail, metallic channel, guide rail；Wherein passed through described upper with screw Guide rail is fixed in upper lid in a hole covering, and parking stall is arranged on pallet by the screens that b confined planes and a positive stop lug boss are constituted Installation in the hole, from different directions install can realize sc parking stall inwardly or lc parking stall inwardly；Fusion joining disk and coiling Post is screwed on pallet, optical cable is coiled in coiling face by the coiling face of wrapping post by tail optical fiber and spacing cantilever is constituted Space in, and flexible jumper is inserted in the sc parking stall on parking stall or lc parking stall；The sliding edge of pallet is put into and is led Realize in gathering sill on rail sliding；Metallic channel passes through the b locating surface laminating on a locating surface and guide rail, spacing with c by hook Metallic channel is arranged on guide rail in face；A confined planes on described pallet are contacted with c confined planes on guide rail, play position-limiting action； During use, pallet is extracted out from described guide rail, tail optical fiber is released from wrapping post, the left wire hole from pallet or right wire hole In pass, directly described flexible jumper is inserted other equipment the corresponding interface, then excess cable disk is returned on described wrapping post, Thus realizing outside fibre distribution box no excess cable, and additionally need not carry out jumper connection using optical patchcord.

Advantages of the present invention: 1) compared with traditional fibre distribution box, increased long function more than storage tail optical fiber, make rack More junction boxs can be installed；2) in use, link load is made to reduce due to having lacked a flexible connection point；3) by Adopt pallet pull in fiber storage type fibre distribution box it is possible to expand fiber capacity as needed.
