Abstract
The invention relates to an optical fiber connector. The optical fiber connector comprises a flange plate and a back sleeve, a guide structure is arranged on the flange plate or the back sleeve, a guide hole is formed in the guide structure, the front end of the guide hole is communicated with an inner hole of the flange plate, the rear end of the guide hole is communicated with an inner hole of the back sleeve, and the guide hole is in a taper shape with the aperture which is gradually reduced from the rear to the front. The guide structure is arranged on the flange plate or the back sleeve so that when glue injection or fiber penetration is performed, a gluing machine needle head or a wire core penetrates from the rear end of the back sleeve, the gluing machine needle head or the wire core can be gradually guided into the inner hole of the flange plate along the tapered hole walls of the guide hole, the gluing machine needle head and a fiber core can be easily inserted into the inner hole of the flange plate, and the assembly success rate of the optical fiber connector is increased.
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: comprise that front end is the housing of inserted terminal, housing comprises the protheca 4 and the rear cover 6 that are assembled together, on housing, rotation has attaching nut 2, in housing, be provided with the ring flange 3 that lock pin 1 is housed, the rear end of ring flange extend in the endoporus of rear cover, for ensureing moving axially of connector when docking ring flange, between the endoporus hole wall of ring flange and rear cover, there is radial play 5.The joints of optical fibre adopt manual assembly in the past, manually by optical fiber by rear to the front endoporus that is installed on ring flange, and then ring flange is assembled in housing.Because of artificial efficiency of assembling lower, just attempting at present adopting automated assembling equipment to produce the joints of optical fibre, but the step of robotization assembling is: first lock pin, ring flange, spring 8, protheca, rear cover etc. are assembled, carry out again injecting glue, fiber stripping, wear the steps such as fine and follow-up grinding, because be injecting glue after first Assembly part, wear fibre, ring flange is distant apart from the rearward end of rear cover, when injecting glue, injecting glue head is very easily blocked and cannot inject ring flange by the rear end face of ring flange, and finally because glue overflows, ring flange is outer to be caused assembling unsuccessfully; While wearing fibre in addition, very easily occur that fibre core 7 enters the radial play between ring flange and rear cover, or fibre core is inserted on the rear end face of ring flange and core fractures, finally cause assembling unsuccessfully.
Summary of the invention
The object of the present invention is to provide a kind ofly after after ring flange, cover assemble, glue needle head or core are easy to by the joints of optical fibre in the endoporus of rear insertion ring flange before.
In order to address the above problem, technical scheme of the present invention is:
A kind of joints of optical fibre, comprise ring flange and rear cover, ring flange or after put and be provided with guide frame, guide frame is provided with the pilot hole that front end is communicated with the endoporus of described ring flange, rear end is communicated with the endoporus of described rear cover, and the shape of described pilot hole is the taper being diminished gradually to front aperture by rear.
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 cover.
The rear end of described ring flange extend in the endoporus of described rear cover, between the endoporus hole wall of the rear end of described ring flange and described rear cover, has radial play, and the outer end of described guide frame is arranged in described radial play.
The large stomidium footpath of described pilot hole is identical with the endoporus aperture of described rear cover, and the small end aperture of described pilot hole is identical with the endoporus aperture of described ring flange.
The large stomidium footpath of described pilot hole is close to the endoporus aperture of described rear cover, and the small end aperture of described pilot hole is close to the endoporus aperture of described ring flange.
Beneficial effect of the present invention is: by ring flange or after put guide frame be set, at injecting glue or while wearing fibre, glue needle head or core are penetrated by the rear end of rear cover, glue needle head or core can be in the taper hole wall of the pilot hole endoporus that is directed to ring flange gradually, make like this glue needle head and fibre core be easy to insert in the endoporus of ring flange, improved the assembly yield of the joints of optical fibre.
Brief description of the drawings
Fig. 1 is the structural representation of background technology in the present invention;
Fig. 2 is that in the present invention, the joints of optical fibre are worn the use constitutional diagram in fine process;
Fig. 3 is the use constitutional diagram of the joints of optical fibre after wearing fibre and finishing in the present invention.
Embodiment
The embodiment of the joints of optical fibre is as shown in Fig. 2 ~ 3: comprise protheca 10, rear cover 13 and front end are equipped with the ring flange 15 of lock pin 9, on protheca, be installed with attaching nut 12, the rear end of ring flange extend in the endoporus of rear cover, between the endoporus hole wall of the rear end of ring flange and rear cover, there is radial play, the rear end of ring flange is installed with guide frame 16, the outer end of guide frame is arranged in radial play, guide frame extend in the endoporus of rear cover, the endoporus hole wall clearance fit of guide frame and rear cover simultaneously, guide frame just can move forward and backward in the endoporus of rear cover like this, the axially-movable of ring flange while not affecting connector docking.Guide frame is provided with the pilot hole 17 that front end is communicated with the endoporus of ring flange, rear end is communicated with the endoporus of rear cover, the shape of pilot hole is the taper being diminished gradually to front aperture by rear, the large stomidium footpath of pilot hole is identical with the endoporus aperture of rear cover, 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.
In the time that reality is used, owing to having adopted automatic assembling, ring flange, protheca, rear cover are first assembled together, then injecting glue and wear fibre, in the time 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 cover, because there is a segment distance rear end of the endoporus of rear cover apart from ring flange, so what core can be can hardly be avoided wears partially, now the leading section of core be directed to hole hole wall guiding and gradually insert the endoporus to ring flange, thereby 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 puts after also can being packed in or is one-body molded with rear cover, and now guide frame is fixture, moves as long as guide frame does not affect the normal axial of ring flange; Guide frame puts after can also being fixed to by screw; Certainly, the rear end of ring flange also can not extend in the endoporus of rear cover, and now both can to have extend in the endoporus of rear cover can be only also the front side that is positioned at rear cover to guide frame; The large stomidium footpath of pilot hole can also be the endoporus aperture close to rear cover, and the small end aperture of pilot hole can also be the endoporus aperture close to ring flange, and the approaching aperture difference that refers to is here between 0 ~ 1mm; Guide frame can be also that slide-and-guide coordinates with the endoporus hole wall of rear cover.
