Description

Opticalfiber conductor

The utility model relates to fibre-optical splice, refers to that especially assembling is rapid, the reliable quality fibre-optical splice.

Optical-fibre communications is flourish in recent years emerging technology, because its transfer rate is fast, distortion rate is low, thus each national capital develop actively optical fiber industry, and regard it as inexorable trend and the main flow that following communication career develops.

And link occasion at fiber optic cables, need connect with fibre-optical splice, because it is orthoscopic that light beam is advanced, so the fibre-optical splice inner gateway is necessary for straight line, simultaneously, its specification requirement is also very accurate, the ceramic stem inner light beam of connector is able to correcting, so it is to the requirement of quality, than general power lug strictness.

The fibre-optical splice of prior art, from the outside, the employing two-piece type is sealed, and each end all has screw thread for locking, its inside, hold its straight degree in order to guarantee for ccontaining core, see through several circular hollow burrs and overlap mutually respectively, the shortcoming of this mode is many when being the millwright, and is improper if any certain element nargin in all multicomponents, can cause the light beam deflection, optical fiber structure integral body can't be used, and What is more, by existing manufacture method, at least comprise ten above assemble flow, output and qualification rate all can't be improved, so the fibre-optical splice price can be in any more at present, simultaneously also under-supply, become an industry difficult problem.

The purpose of this utility model is to provide a kind of fibre-optical splice.

The purpose of this utility model is achieved in that promptly provides a kind of fibre-optical splice, and it comprises: a front stall, extend the preceding seat ring of a cylinder integratedly by a square front stall sheet, and peripheral tool front stall thread, and along continuous straight runs is established a front stall annular groove; One core pipe is the rectangular tube of circle; One back seat, it is corresponding to front stall, and tool one back seat ring have the back seat thread, and along continuous straight runs is established a back seat annular groove; Before in the seat ring cylinder, from the front stall sheet extend integratedly one with the front stall stem stem of preceding seat ring concentric, and surround a front stall core hole for ccontaining core pipe, its leading edge is inwardly splayed and is prominently established an annular front stall core edge, its rear then is the bigger preceding seat pillar hole of internal diameter; Back seat also extends a back seat stem stem from the back seat sheet integratedly in the seat ring of back, surround a back seat core hole therebetween for ccontaining core pipe, its end is inwardly splayed and the prominent annular back seat core edge of establishing, the back seat pillar concentric with preceding seat pillar hole extended in the place ahead of back seat sheet integratedly, and mat core pipe is embedded in the seat pillar hole, front and back, before and after seat core edge fixed core pipe, and with screw closure front stall film perforation and back seat film perforation.

Advantage of the present utility model is assembly because one-body molded and quantity reduces, the bad cooperation that elimination is caused because of each part specifications shakiness (excessive as the nargin that multiple assembling produced), assembling is reduced work hours fast, and the precision of raising finished product, reliable in quality.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:

Fig. 1 is the three-dimensional exploded view of the utility model joint;

Fig. 2 is the assembled sectional view of the utility model joint.

As shown in Figure 1, joint of the present utility model is made up of a front stall 1, a core pipe 2 and a back seat 3.

Wherein front stall 1 has a square front stall sheet 11, establish front stall film perforation 12 for its four jiaos, for locking with back seat 3, the one side, the one cylindraceous preceding seat ring 13 that extends is arranged, and periphery has front stall thread 131, and along continuous straight runs is provided with a front stall annular groove 132, is connected and uses (this is prior art, and the outward appearance of present fibre-optical splice has standard specification) for link time location or bolt with fiber optic cable connectors.Structure of the present utility model, see also Fig. 2, they are in preceding seat ring 13 cylinders, from stretch out front stall stem stem 14 with preceding seat ring 13 concentrics of front stall sheet 12 one, its development length is no more than preceding seat ring 13 front ends and is recessed shape, the round wall of this front stall stem stem 14 surrounds the front stall core hole 15 of a circle, wherein front stall core hole 15 leading edges are inwardly splayed and the prominent annular front stall core edge 16 of establishing, stop core pipe 2 described later to drop out, front stall core hole 15 rear sides are then for concentric and the bigger preceding seat pillar hole 17(Fig. 2 of internal diameter) pass through for the back seat pillar 36 of back seat 3.

The rectangular tube of core pipe 2 for being surrounded by phosphate bronze tube or ceramic pipe, but the ceramic stem on the caulked connector in its internal diameter, external diameter can be located behind the fit then corresponding to aforementioned front stall core hole 15.

Back seat 3 is similar to front stall 1, has a back seat sheet 31, four jiaos have back seat film perforation 32, and its outer end (being the rear end) has the evagination of a back seat ring 33, and it has back seat thread 331 and has back seat annular groove 332(genus prior art), and in seat ring 33 inside, back, extend a back seat stem stem 34 with one heart integratedly from back seat sheet 31, its end also is recessed shape, surrounds the back seat core hole 35 of a circle, whole back seat 3 is run through in back seat core hole 35, and corresponding to the external diameter of core pipe 2.Wherein back seat core hole 35 ends are inwardly splayed and the prominent annular back seat core edge 36 of establishing, and come off with restriction core pipe 2, simultaneously, for make its can with front stall 1 fit, in back seat sheet 31 the place aheads, extend a back seat pillar 37 concentric integratedly with back seat core hole 35, its size is corresponding to the preceding seat pillar hole 17 of front stall 1.

During operation, front stall 1 is one-body molded through die casting with back seat 3, to obtain than high precision.

When combination, as shown in Figure 2, at first the back seat core hole 35 of core pipe 2 from back seat 3 penetrated, and be backstop, drop to prevent core pipe 2 with back seat core edge 36, again with back seat 3 through after seat pillar 37 embed before in the seat pillar hole 17, front stall core edge 16 plays the backstop effect, drop out from front stall core hole 15 to prevent core pipe 2, with back seat core edge 36 fixed core pipes 2 after, front stall annular groove 132 and back seat annular groove 332 equidirectional aligning, and with screw closure front stall film perforation 12 and back seat hole 32.
