Example one

Referring to fig. 1, according to the utility model provides a novel optical fiber distribution frame, splice tray 100 and ring flange 400 including the components of a whole that can function independently setting, splice tray 100's one end butt fusion has the optical cable 110 of coming to the station, be connected with tail cable 300 between splice tray 100 and the ring flange 400, the one end butt fusion of tail cable 300 is in splice tray 100, be provided with reason line board 200 between the other end of tail cable 300 and the ring flange 400, can dismantle along controlling the direction interval on the ring flange 400 and be connected with twelve flange heads 420, every flange head 420 all includes an input interface 421 and an output interface 422, input interface 421 is connected with the tail fiber of tail cable 300, output interface 422 pegs graft there is business tail fiber 410, the other end of business tail fiber 410 is used for connecting all kinds of communications facilities. Compared with the prior art, the embodiment of the present invention sets the splice tray 100 and the flange 400 as two separate parts, the two parts are connected by the tail cable 300, the distance between the splice tray 100 and the flange 400 is increased, and the flange 420 is detachably connected to the flange 400, compared with the conventional optical fiber distribution frame, when the operations of replacing the flange 420 and increasing the optical attenuator are performed, the optical fiber distribution tray with the splice tray 100 and the flange 400 integrally arranged and the cover plate of the distribution frame are pulled out, and the replacement is performed, but because the splice tray 100 fixes the optical fiber cable 110 entering the station with a binding wire after the optical fiber cable 110 entering the station is welded, the fiber core of the optical fiber cable 110 entering the station in the splice tray 100 is easily interrupted, and there is a risk point of service interruption, when the present invention is performed, the operator only needs to pull out the tail fiber and the service tail fiber 410 of the tail cable 300 on the input interface 421 and the output interface 422 spliced on the flange 420, the flange head 420 can be detached for replacement or replaced with the flange head 420 with the optical attenuator, so that the problem that the operation of replacing the flange head 420 of the traditional optical fiber distribution frame, increasing the optical attenuator and the like is inconvenient is solved; when the tail fibers of the tail cables 300 of two adjacent optical fiber distribution frames are not consistent in fiber sequence, only one of the optical fiber distribution frames is used as a reference, the tail fibers of the tail cables 300 with different fiber sequences are pulled out from the original input socket 421 and replaced to the corresponding input socket 421, and when the positions of the tail cables 300 welded on the fusion splice tray 100 are wrong and the fiber sequences are different, the two tail fibers of the tail cables 300 need to be intermodulation with the input socket 421 of the flange head 420 at different positions, and only the tail fibers of the two tail cables 300 which are oppositely spliced need to be pulled out from the original input socket 421 to be transposed for re-splicing; the problem of difficult adjustment of the fiber sequence of the traditional optical fiber distribution frame is solved; when the flange head 420 is required to be detected to be in fault or the contact between the distribution fiber core in the disc and the flange head 420 is good, only the tail fiber of the tail cable 300 inserted into the input insertion port 421 is required to be taken out, and the ODTR test is used, so that the inspection is convenient, and the daily operation and maintenance and the fault positioning work are greatly facilitated; through installing a plurality of flange heads 420 on ring flange 400 along left right direction interval, can increase the spacing distance between the adjacent tail optical fiber, solved because of the spacing distance undersize between the adjacent tail optical fiber of traditional fiber optic distribution frame, very easily miss when pulling out and inserting and touch adjacent tail optical fiber at the operation equipment, cause communication accident's such as service interruption problem.

Preferably, a label column 430 is disposed on the flange plate 400 below the flange head 420 in the left-right direction, and the label column 430 is used for placing an identification label. Compared with the traditional optical fiber distribution frame, the identification label is attached to the service tail fiber 410 for identification, the embodiment of the utility model has the advantages that the label column 430 is arranged on the flange plate 400, so that the identification label is conveniently attached to the label column 430 by an operator for identification, and the identification label is not easy to fall off; and the label column 430 can increase the distance between the input interface 421 on two adjacent flanges 400 in the up-down direction, so that when the fiber sequence on different flanges 400 is wrong and needs to be adjusted, the tail fibers of the tail cables 300 plugged on the input interface 421 on different flanges 400 can be conveniently pulled out and the positions of the tail fibers can be interchanged for plugging. For example, when twenty-four cores are required to be transmitted, two tail cables 300 are welded to the fusion splice tray 100, the two tail cables 300 are respectively connected to the two flange plates 400, and due to the welding error of the tail cables 300 on the fusion splice tray 100, the tail fiber of the tail cable 300 which should be originally plugged into the input plug port 421 of the leftmost flange head 420 of the first flange plate 400 should be actually plugged into the input plug port 421 of the leftmost flange head 420 of the other flange plate 400; the pigtail of the pigtail cable 300 that should be plugged into the input plug 421 of the leftmost flange 420 of the second flange 400 should actually be plugged into the input plug 421 of the leftmost flange 420 of the first flange 400, and at this time, only the pigtail of the pigtail cable 300 that should be plugged into the input plug 421 at the wrong position needs to be pulled down to change over the position and plugged into the corresponding input plug 421.

Preferably, a threaded hole is formed in the flange 400 at a position corresponding to the flange head 420, and a through hole is formed in the flange head 420 at a position corresponding to the threaded hole, and is used for a screw to pass through and be matched with the threaded hole. With the arrangement, when the flange head 420 needs to be replaced and the optical attenuator needs to be added, the pigtails of the pigtails 300 and the service pigtails 410 which are plugged into the input plug-in port 421 and the output plug-in port 422 of the corresponding flange head 420 need to be pulled out, the original flange head 420 can be taken down by screwing down the screws, and the flange head 420 with the optical attenuator needs to be replaced, so that the operation is simple and convenient. It will be appreciated that the flanged head 420 with the optical attenuator may be configured without the flanged head 420 of the optical attenuator by the same operation.

Example two

The embodiment of the utility model provides a compare with embodiment one, the difference lies in, and the position that corresponds flange head 420 on the ring flange 400 is provided with the screens, and the position that corresponds the screens on the flange head 420 is provided with the buckle. By such arrangement, the flange head 420 is detachably mounted on the flange 400 in a clamping manner, when the operations of replacing the flange head 420, adding an optical attenuator and the like are required, only the pigtails of the pigtails 300 and the service pigtails 410 of the pigtails are required to be unplugged from the input interface 421 and the output interface 422 of the corresponding flange head 420, and then the original flange head 420 is taken down and replaced by the flange head 420 with the optical attenuator, so that the operation is simple and convenient. It will be appreciated that the flanged head 420 with the optical attenuator may be configured without the flanged head 420 of the optical attenuator by the same operation.
