Abstract

The utility model discloses a pigtail fiber containment disk, comprising a pigtail fiber winding disk and pigtail fiber wiring channels. The pigtail fiber winding disk is designed into two adjacent containment circular disks, the pigtail fiber wiring channels are arranged between the winding disk and a disk wall of the containment disk and among the winding disks. One side wall of the containment disk is convexly provided with a pivot shaft hole, one side wall of the pivot shaft hole is provided with a pigtail fiber inlet hole, and the other side wall of the containment disk is extensively provided with an outlet channel box. Pigtail fibers can be wound on the circumference of the winding disks, the pigtail fibers in the containment disk can not be folded and pulled because the pigtail fibers are drawn inside and are connected outside, and the operation, taking and placement of the pigtail fibers are convenient.

Description

The tail optical fiber storing tray

The utility model relates to the annex of optical-fibre communications equipment, more specifically is meant a kind of tail optical fiber storing tray that the optical fiber cable termination welding connects case that is used for.

In existing optical fiber cable termination connects, its unnecessary tail optical fiber normally is placed in the casing as drawer type, when to optical-fibre communications maintenance of equipment, test, installation, the drawer type casing that needs to shelve tail optical fiber is pulled out, because when drawing casing, being the irregular tail optical fiber of shelving and drawing in thereupon pull out in it, in this process, tail optical fiber can be subjected to folding unavoidably and draw, like this, the light signal in optical fiber loss to a certain extent increases, in the course of time, the life-span of tail optical fiber also can be affected, and very inconvenience is also felt in operation.

The purpose of this utility model provides a kind of optical fiber cable termination welding and connects the tail optical fiber storing tray that case is used.

To achieve these goals, the utility model adopts following technical scheme: storing tray includes tail optical fiber winding disc and tail fiber trunking, wherein, the tail optical fiber winding disc is designed to two adjacent circular discs of accommodating, be between Pan Bi and winding disc and the winding disc around winding disc and the storing tray and offer into tail fiber trunking, one sidewall of storing tray convexes with a pivot hole, offers the tail optical fiber ingate at a sidewall of pivot hole, and another sidewall of storing tray has extended one and gone out Wire casing boxes.

Because the utility model adopts and to include the storing tray that tail optical fiber winding disc and tail fiber trunking constitute and deposit tail optical fiber, make that the tail optical fiber in the memory disc can not be subjected to folding and not draw because of drawing in to pick out, and access tail optical fiber easily.

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model schematic perspective view.

Fig. 3 is that the utility model flange stator, reinforced sheet are loaded onto the back schematic perspective view.

See also Fig. 1-shown in Figure 2, tail optical fiber storing tray 1 includes tail optical fiber winding disc 2 and tail fiber trunking 3, wherein, tail optical fiber winding disc 3 is designed to two adjacent circular discs of accommodating, two circular discs such as same " 8 " font are coiled around winding disc 2 and the storing tray 1 to be between wall 4 and winding disc 2 and the winding disc 2 and are offered into tail fiber trunking 3.Two tail optical fiber winding discs 2 all interval extension are provided with catch 21, each winding disc 2 is provided with four catch 21 in the drawings, dish wall 4 around the storing tray 1 also interval extension is provided with catch 41, equally, catch 41 has also been established four, the quantity of catch 21 and catch 41 is not limited, and catch 21 and catch 41 can be fixed in the tail optical fiber of placing in the tail fiber trunking 3 in the trough 3.One sidewall top of storing tray 1 convexes with a pivot hole 5, and when having pivot to insert in the pivot hole 5, whole tail optical fiber storing tray 1 can pivot.Same sidewall at nearly pivot hole 5 also offers tail optical fiber ingate 6, enter in the storing tray 1 tail optical fiber just from then on ingate 6 enter, extended a location card 9 at the other end with the same sidewall of ingate 6, pack into when pivoting after optical cable connects case when storing tray 1, positioning cards 9 can make storing tray 1 locate in connecting casing.The rear wall of storing tray 1 also can be designed to arc, and rear wall also is cambered surface with being connected of two side, and this moment, positioning cards 9 was just extended from the backarc sidewall.Another sidewall of storing tray 1 has extended one and has gone out Wire casing boxes 7, the top that goes out Wire casing boxes 7 is equipped with a dismountable flange stator 8 (as Fig. 3), offer tail optical fiber outlet opening 81 on the flange stator 8, the number of outlet opening 81 can 2-3, just picks out outside the storing tray in tail optical fiber outlet opening 81 through the tail optical fiber after twining.

This tail optical fiber storing tray 1 can adopt the plastics mould one-body molded on making, and on storing tray 1 pivot hole 5 and nearly 5 liang of crossing Pan Bi of pivot hole a reinforced sheet 51 (as Fig. 3) is set, and increases the intensity herein of storing tray 1.
