Abstract

The utility model provides an optical fiber welding tray on which positive face a multi-fiber welding slot is arranged, and is characterized in that a plurality of optical fiber keeps are arranged on the positive face and negative face of the optical fiber welding tray, and at least two through-fiber holes which are through the positive face and negative face. The optical fiber welding tray had better be circular disk, and thus is not restricted by a particular angle when a stent is inserted, that is no positioning is needed; in order to be neater in use, a cover plate is arranged on the positive face and negative face of the optical fiber welding tray and had better be made of transparent material. The stent for inserting in particular the optical fiber welding tray includes a plurality of bearing plates which are in parallel arranged and tilt slightly to the side of the rack, the optical fiber welding tray is inserted in the space between the bearing plates which are adjacent up and down, and is supported by the lower bearing plate. Compared with the prior art, the utility model has the advantages which the optical fiber welding tray is taken out of the stent of the optical fiber welding tray completely and optical fiber and tail fiber are respectively coiled around the positive face and negative face, so that operators truly free coil and connect fibers.

Description

A kind of fused fiber splice dish and support thereof

Technical field

The utility model relates to a kind of fused fiber splice dish and support thereof that is used for fibre distribution frame.

Background technology

In the prior art, each fibre bundle in the optical fiber and each the tail optical fiber Shu Erzhe in the tail optical fiber carry out welding in the fused fiber splice dish, and have the function of the surplus long part of coiled fiber or tail optical fiber.Usually, the fused fiber splice dish is a plurality of to be overlayed in the fibre distribution frame side by side, and run through its bight axis hole by the rotating shaft on the distributing frame, each fused fiber splice dish all shifts out distributing frame around this rotating shaft rotation, fine with convenient dish, molten fine, as being that 97192047.8 Chinese patent application " method and system that is used for making the optical fiber splicer in the fibre distribution frame to switch on and off " and number of patent application are 00222619.7 Chinese patent application " high density welding terminal integrated fiber distributing frame " at number of patent application, all disclose such fused fiber splice dish, the former is vertical the setting, about arrange, the latter is for being horizontally disposed with, be arranged above and below, but same be that optical fiber and tail optical fiber all are coiled on the same end face; Because such fused fiber splice dish can only rotate in the rotating shaft on distributing frame, and can't take out from distributing frame fully, therefore actual when connecing fibre operator's action be subjected to bigger restriction, be difficult to operation freely, and optical fiber and tail optical fiber all are coiled on the same end face of fusion joining disk, its space seems crowded, and has increased operation easier further.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of operator's of making freedom around fused fiber splice dish and support thereof fine, that connect fibre at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: the front of fused fiber splice dish is provided with the multi-core fiber weld slot, it is characterized in that being provided with a plurality of optical fiber retaining clips, and be provided with two wire holes that run through pros and cons at least at the pro and con of fused fiber splice dish.

Described fused fiber splice dish is good with disc, need not to be subjected to the restriction of special angle like this when inserting support, promptly need not the location; For can be more clean and tidy in use, described fused fiber splice dish also can be provided with cover plate in its front and reverse side, its material with transparent be good.

Be exclusively used in the support that inserts described fused fiber splice dish and include a plurality of be arranged in parallel and slightly to the support plate of the lopsidedness of frame, described fused fiber splice dish inserts in the space between neighbouring support plate, and by wherein lower supporting plates supports.

Compared with prior art, advantage of the present utility model is that the fused fiber splice dish can take out fully from its support, and optical fiber and tail optical fiber can be coiled in respectively on its pro and con, thereby makes the real realization of operator freely carry out around fibre, connect fine operation.

Embodiment

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

As Fig. 1～shown in Figure 4, fused fiber splice dish 1 is disc, the front of disk body 1 is provided with multi-core fiber weld slot plate 2, the draw-in groove plate is provided with a plurality of draw-in grooves 21, be provided with a plurality of optical fiber retaining clips 12 at the disk body pro and con, in the present embodiment, these retaining clips are injection molded with inner tray 1 one, are provided with two wire holes 11 that run through pros and cons symmetrically in the position of disk body 1 close side;

Referring to Fig. 3, during use, tail optical fiber 3 is coiled in the front of disk body 1, optical fiber 4 enters from the front of disk body 1, behind one of them wire hole 11, unnecessary length part is coiled back (referring to Fig. 4) reenters disk body 1 again from another wire hole front at disk body 1 reverse side, an end corresponding welding respectively that each fibre bundle 41 and tail optical fiber bundle 31 expose, put heat-shrinkable T bush 22 and be stuck in the weld slot 21 at the welding point then, make it firmly motionless.

For can be more clean and tidy in use, described fused fiber splice dish 1 also can be in its front and reverse side be provided with cover plate 5, referring to Fig. 5, Fig. 6, its material with transparent be good.

As shown in Figure 7, described fused fiber splice disc carrier includes a plurality of be arranged in parallel and slightly to the lopsidedness support plate 6 of frame 7, and described fused fiber splice dish 1 inserts in the space between neighbouring support plate 6, and by wherein lower support plate 6 supportings.
