Description
Technical field
The present invention relates to a kind of optical-fiber coupling connector.
Background technology
In optical-fibre communications, photoelectric conversion module is to assemble optical signal to optical fiber with lens or the optical signal of fiber-optic transfer imports photoelectric detector, and wherein optical fiber and lens be that after utilizing the fixing optical fiber of jumper (jumper), the mutual card structure of recycling photoelectric conversion module and jumper realizes to criterion.
In order to ensure the card not the biggest inclination mutually between photoelectric conversion module and jumper, it will usually fixed plus a metal buckle outside photoelectric conversion module and jumper.Owing to optical fiber align needs the highest precision and degree of stability, easily there is pine or the problem of tension when snapping in jumper in existing metal buckle structure.
Summary of the invention
In view of this, it is necessary to provide a kind of and engage the optical-fiber coupling connector that dynamics is suitable.
A kind of optical-fiber coupling connector, including photoelectric conversion module, jumper and metal buckle, described photoelectric conversion module matches with described jumper and realizes the transmission of optical signal, described metal buckle is used for fixing described photoelectric conversion module and jumper, described jumper has draw-in groove, described draw-in groove extends to the direction away from described photoelectric conversion module and the degree of depth of described draw-in groove is gradually increased to the direction away from described photoelectric conversion module, and described metal buckle has the first claw being fastened in described draw-in groove.
Compared to prior art, the draw-in groove of the jumper of the present embodiment has a surface tilted, therefore, first claw can be fastened in draw-in groove in the way of importing, so that the first claw is tight after elder generation pine when group enters in draw-in groove, metal buckle is made to control in optimal strength, it is ensured that buckle did not knew pine or tension.

Following detailed description of the invention will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
Seeing also shown in Fig. 1, Fig. 2 and Fig. 3, the optical-fiber coupling connector 10 that the embodiment of the present invention provides includes circuit board 11, photoelectric conversion module 12, jumper 13 and metal buckle 14.
Photoelectric conversion module 12 is arranged on circuit board 11 for being assembled to optical fiber by jumper 13 by optical signal or being coupled in the photoelectric detector (not shown) being arranged on circuit board 11 by jumper 13 by the optical signal of fiber-optic transfer.
Being respectively provided with two locating dowels 121 and two breach 122 on two surfaces that photoelectric conversion module 12 is relative, locating dowel 121 is used for being mutually located with jumper 13 being directed at, and breach 122 is used for engaging metal buckle 14.
The locating dowel 121 of the corresponding photoelectric conversion module 12 of jumper 13 has lens 132 and two draw-in grooves 133 that hole 131, two location is optically coupled with photoelectric conversion module 12.So that photoelectric conversion module 12 and the mutual para-position of jumper 13 in locating dowel 121 stretches into hole 131, location.Two draw-in grooves 133 be arranged in parallel and substantially parallel circuit board 11 is arranged and extend to the direction away from photoelectric conversion module 12.
Certainly, photoelectric conversion module 12 can arrange hole, location, and on jumper 13, locating dowel is set.
The degree of depth of draw-in groove 133 is gradually increased to the direction away from photoelectric conversion module 12, so that draw-in groove 133 has a surface 134 tilted.
Metal buckle 14 is used for fixing engaging photoelectric conversion module 12 and jumper 13, and has certain elasticity.Metal buckle 14 includes 140, two the first claws 141 of plate body and two the second claws 142, and the first claw 141 is positioned at the relative both sides of plate body 140 and substantially parallel plate body 140 with the second claw 142.The width of the first claw 141 is equal to or less than the width of draw-in groove 133, the minimum-depth of the thickness of the first claw 141 no more than draw-in groove 133 is so that the first claw 141 is unlikely to exceed the surface of jumper 13 after snapping in draw-in groove 133, and the width of the second claw 142 is equal to or less than the width of breach 122.
Second claw 142 is fastened in the breach 122 of photoelectric conversion module 12, and the first claw 141 is then fastened in the draw-in groove 133 of jumper 13, thus photoelectric conversion module 12 and jumper 13 is fixed.
Owing to draw-in groove 133 has a surface 134 tilted, and the degree of depth is gradually increased to the direction away from photoelectric conversion module 12, therefore, first claw 141 is fastened in draw-in groove 133 in the way of importing, so that the first claw 141 is tight after elder generation pine when group enters in draw-in groove 133, metal buckle 14 is made to control in optimal strength, it is ensured that buckle was unlikely to pine or tension.
Further, since the draw-in groove 133 of jumper 13 has inclined surface 134 so that draw-in groove 133 can amplify tolerance rate in mould tolerance, reduce processing and the cost that repairs a die.
It is understood that those skilled in the art also can do other change etc. in spirit of the present invention is used in the design of the present invention, without departing from the technique effect of the present invention.These changes done according to present invention spirit, within all should being included in scope of the present invention.
