Abstract
The present invention relates to a kind of joints of optical fibre, including ring flange and rear enclosure, it is provided with guide frame on ring flange or rear enclosure, guide frame is provided with the pilot hole that front end connects, rear end connects with the endoporus of described rear enclosure with the endoporus of described ring flange, and the shape of described pilot hole is in by the rear taper tapered into front aperture.By arranging guide frame on ring flange or rear enclosure, at injecting glue or when wearing fibre, glue needle head or core are penetrated by the rear end of rear enclosure, glue needle head or core gradually can be directed in the endoporus of ring flange along the taper hole wall of pilot hole, so make glue needle head and fibre core be easily inserted in the endoporus of ring flange, improve the assembly yield of the joints of optical fibre.
Description
Technical field
The present invention relates to the joints of optical fibre for optical signal transmission.
Background technology
The structure of the joints of optical fibre such as existing FC, SC is as shown in Figure 1: include the housing that front end is inserted terminal, housing includes protheca 4 and the rear enclosure 6 being assembled together, rotate on housing and have attaching nut 2, housing is provided with the ring flange 3 equipped with lock pin 1, the rear end of ring flange extend in the endoporus of rear enclosure, the moving axially of ring flange during for ensureing adapter docking, has radial clearance 5 between the endoporus hole wall of ring flange and rear enclosure.The joints of optical fibre used manual assembly in the past, manually by optical fiber by rear to the front endoporus being installed on ring flange, were assembled in housing by ring flange the most again.Because artificial efficiency of assembling is relatively low, currently attempt using automated assembling equipment to produce the joints of optical fibre, but the step of Automated assembly is: first lock pin, ring flange, spring 8, protheca, rear enclosure etc. are assembled, carry out injecting glue, fiber stripping again, wear the steps such as fine and follow-up grinding, because being injecting glue after first Assembly part, wearing fibre, the ring flange rearward end away from rear enclosure is distant, during injecting glue, injecting glue head is easily blocked by the rear end face of ring flange and cannot inject ring flange, finally causes assembling unsuccessfully outside ring flange because glue overflows；Easily occur when additionally wearing fibre that fibre core 7 enters the radial clearance between ring flange and rear enclosure, or fibre core is inserted into core on the rear end face of ring flange and fractures, and ultimately results in and assembles unsuccessfully.
Summary of the invention
It is an object of the invention to provide a kind of after ring flange rear enclosure assemble, glue needle head or core are prone to by the joints of optical fibre in the endoporus of the insertion ring flange before rear.
In order to solve the problems referred to above, the technical scheme is that
A kind of joints of optical fibre, including ring flange and rear enclosure, it is provided with guide frame on ring flange or rear enclosure, guide frame is provided with the pilot hole that front end connects, rear end connects with the endoporus of described rear enclosure with the endoporus of described ring flange, and the shape of described pilot hole is in by the rear taper tapered into front aperture.
Described guide frame is arranged on described ring flange.
Described guide frame spinning is in described ring flange rear end.
What described guide frame can move forward and backward extend in the endoporus of described rear enclosure.
The rear end of described ring flange extend in the endoporus of described rear enclosure, has radial clearance between rear end and the endoporus hole wall of described rear enclosure of described ring flange, and the outer end of described guide frame is positioned in described radial clearance.
The big stomidium footpath of described pilot hole is identical with the endoporus aperture of described rear enclosure, and the small end aperture of described pilot hole is identical with the endoporus aperture of described ring flange.
The big stomidium footpath of described pilot hole is close to the endoporus aperture of described rear enclosure, and the small end aperture of described pilot hole is close to the endoporus aperture of described ring flange.
The invention have the benefit that by arranging guide frame on ring flange or rear enclosure, at injecting glue or when wearing fibre, glue needle head or core are penetrated by the rear end of rear enclosure, glue needle head or core gradually can be directed in the endoporus of ring flange along the taper hole wall of pilot hole, so make glue needle head and fibre core be easily inserted in the endoporus of ring flange, improve the assembly yield of the joints of optical fibre.
Accompanying drawing explanation
Fig. 1 is the structural representation of background technology in the present invention；
Fig. 2 is the use state diagram during fibre worn by the joints of optical fibre in the present invention；
Fig. 3 is that in the present invention, the use state diagram after fibre terminates worn by the joints of optical fibre.
Detailed description of the invention
The enforcement of the joints of optical fibre is such as shown in Fig. 2 ~ 3: include protheca 10, rear enclosure 13 and front end are equipped with the ring flange 15 of lock pin 9, attaching nut 12 it is installed with on protheca, the rear end of ring flange extend in the endoporus of rear enclosure, between rear end and the endoporus hole wall of rear enclosure of ring flange, there is radial clearance, the rear end of ring flange is installed with guide frame 16, the outer end of guide frame is positioned in radial clearance, guide frame extend in the endoporus of rear enclosure, it is simultaneously directed to the endoporus hole wall matched in clearance of structure and rear enclosure, so guide frame just can move forward and backward in the endoporus of rear enclosure, the axially-movable of ring flange when not affecting adapter docking.Guide frame is provided with the pilot hole 17 that front end connects, rear end connects with the endoporus of rear enclosure with the endoporus of ring flange, the shape of pilot hole is in by the rear taper tapered into front aperture, the big stomidium footpath of pilot hole is identical with the endoporus aperture of rear enclosure, and the small end aperture of pilot hole is identical with the endoporus aperture of ring flange.Figure middle term 11 represents spring；Item 14 represents tail sheaths.
When actually used, owing to have employed assembling automatically, ring flange, protheca, rear enclosure are first assembled together, then injecting glue and wear fibre, when wearing fibre (or injecting glue), the core 19(of optical cable 18 or glue needle head) stretched into by the rear end of the endoporus of rear enclosure, owing to the rear end distance ring flange of the endoporus of rear enclosure has a segment distance, so core can hardly be avoided wear partially, now the leading section of core is directed to the hole wall guiding in hole and gradually inserts the endoporus to ring flange, thus ensure accurately installing of core, improve the assembly yield of the joints of optical fibre.
In other embodiments of the invention: guide frame can also be one-body molded with ring flange；Certainly guide frame can also be packed in rear enclosure or one-body molded with rear enclosure, and now guide frame is fixture, as long as the normal axial that guide frame does not affect ring flange moves；Guide frame can also be fixed in rear enclosure by screw；Certainly, the rear end of ring flange can not also extend in the endoporus of rear enclosure, and now guide frame both can extend into the front side that can also only be in rear enclosure in the endoporus of rear enclosure；The big stomidium footpath of pilot hole can also is that the endoporus aperture close to rear enclosure, and the small end aperture of pilot hole can also is that the endoporus aperture close to ring flange, here close to referring to aperture difference between 0 ~ 1mm；Guide frame can also be that slide-and-guide coordinates with the endoporus hole wall of rear enclosure.
