Abstract
The utility model relates to the technical field of optical fiber connection fittings, and in particular relates to a novel multicore optical fiber connector. The novel multicore optical fiber connector comprises a body and connection bodies. A guide channel is arranged on the body. A number of optical fiber through holes are arranged side by side on each connection body. Spacing holes whose number is equal to the number of the optical fiber through holes are arranged on the front end face of the body. The rear end of each spacing hole is connected with the guide channel. Two guide holes are further arranged on the front end face of the body. Two guide columns which are in alignment insertion connection with the guide holes are arranged on the rear end face of each connection body. According to the utility model, through alignment insertion connection of the body and the two connection bodies, rapid and precise optical fiber butt joint is realized; due to the fact that the front end of each spacing hole and the rear end of each optical fiber through hole are in cone-shaped alignment insertion connection, seamless butt joint of the connector is ensured; the aperture of each spacing hole and the outer diameter of each optical fiber are similar; through adhesive layers, gaps between each spacing hole and each optical fiber and between optical fibers are blocked; without an optical fiber aligning component, rapid and precise optical fiber butt joint is realized; and the novel multicore optical fiber connector is very practical.
Description
Technical field
The utility model relates to optical fiber connection fittings technical field, especially a kind of novel multi-fiber connector.
Background technology
The joints of optical fibre, be optical fiber with optical fiber between carry out the device that detachable (activity) is connected, it gets up the accurate butt joint of two end faces of optical fiber, go so that the luminous energy of launching fiber output can be coupled to receive in the optical fiber to greatest extent, and make because it is got involved optical link and the influence that system causes is reduced to minimum.
Traditional multi-fiber connector is in order to realize accurately fixing, the butt joint of two ends fibre ribbon, all be respectively arranged with the fixedly centralising device that cooperatively interacts in each of two ends butt joints outside to bare fibre, and bare fibre is placed on respectively fixedly in the centralising device, when connector need carry out many when optical fiber is connected, then need to arrange many to fixing centralising device accordingly, make that like this volume of whole connector is big, and complex structure, cost height.In addition, the existing fibre ribbon that butts up against in the multi-fiber connector, the bare fibre that the one end exposes is generally very short, and termination or the length of each bare fibre of butt joint can not be on all four, like this, the fibre ribbon at two ends is in butt joint, bare fibre can littlely not bent, also skew that can be not slight, thus bare fibre can not adjusted voluntarily by little curved amount, be difficult to realize butt joint accurately, the butt joint success ratio is not high.
Summary of the invention
At above-mentioned the deficiencies in the prior art, it is a kind of simple in structure that the purpose of this utility model is to provide, the accurate novel multi-fiber connector of fiber alignment.
To achieve these goals, the utility model adopts following technical scheme:
A kind of novel multi-fiber connector, it comprises body and connector, offer for the front end with connector on the described body and be inserted into intrinsic guide channel, on the described connector side by side offer a plurality of optical fiber through holes, the front end face of described body offers the spacing hole with optical fiber through hole equivalent amount, and the rear end of described spacing hole is communicated with guide channel;
The front end face of described body also offers two pilot holes, and the rear end face of described connector is provided with two guideposts of pegging graft with the pilot hole contraposition.
Preferably, described spacing hole front end is the taper type shrinkage pool, and the rear end of described optical fiber through hole extends rearward to be taper type.
Preferably, the inwall of described spacing hole is provided with adhesive layer.
Preferably, the length of described spacing hole is 0.3-0.5mm.
Owing to adopted such scheme, the utility model can peg graft to realize that the fast and accurate of optical fiber docks by body and the contraposition of two connectors, because being the frustum type contraposition, the rear end of spacing hole front end and optical fiber through hole pegs graft, can guarantee the slitless connection of connector, simultaneously, the aperture of spacing hole is close with the external diameter of optical fiber, and intercept slit between spacing hole and optical fiber, optical fiber and the optical fiber by being arranged on adhesive layer on the spacing hole inwall, it need not optical fiber aligning parts, can realize fast and accurate fiber alignment, have very strong practicality.
Description of drawings
Fig. 1 is the STRUCTURE DECOMPOSITION synoptic diagram of the utility model embodiment;
Fig. 2 is the schematic cross-section under the use state of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As depicted in figs. 1 and 2, the novel multi-fiber connector of present embodiment, it comprises body 1 and connector 2, offer for the front end with connector 2 at body 1 and to be inserted into guide channel 3 in the body 1, on the connector 2 side by side offer a plurality ofly for interting and the optical fiber through holes 4 of Primary Location optical fiber, the front end face of body 1 offers and spacing hole 5 optical fiber through hole 4 equivalent amounts, that be communicated with the front end of guide channel 3; The exposed part of optical fiber is positioned in the spacing hole 5 and by spacing hole 5 and docks with the optical fiber that needs to dock, and the front end of spacing hole 5 is the taper type shrinkage pool, and the rear end of optical fiber through hole 4 extends rearward to be taper type; With this, use simultaneously when carrying out fiber alignment at body 1 and two connectors 2, guarantee the seamless link of connector 2 and body 1.
Simultaneously, be accurate be connected and fixing that guarantees connector 2 and body 1, also offer two pilot holes 6 at the front end face of body 1, be provided with two guidepost (not shown)s with pilot hole 6 contrapositions grafting at the rear end face of connector 2.For eliminate optical fiber with spacing hole 5, dock the slit between the optical fiber, be attached with the adhesive layer (not shown) at the inwall of spacing hole 5.
In view of the length of spacing hole 5 can exert an influence to the precision of fiber alignment, too short as spacing hole 5, can reduce optical fiber bearing accuracy in the vertical direction, the spacing hole 5 long optical fiber bearing accuracies in the horizontal direction that then can reduce; So the length of spacing hole 5 is arranged between the 0.3-0.5mm.
The above only is preferred embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
