The product of MOLEX in prior art, develops based on existing MPO lock pin, and MPO lock pin exists itThe defect of self: have fine high inconsistent situation owing to exposing to the naked fine of lock pin one end, thereby cause peaceThe focal plane of lens and the end face of naked fibre that are contained in insertion core end face depart from, and therefore make the light beam of transmitting to becomeDivergent shape (perfect condition is directional light), finally causes receiving terminal optical signal can not be coupled to receiving terminal completelyIn optical fiber, cause the loss of optical signal, increased the insertion loss value of the whole joints of optical fibre. In like manner,If the end face that receives optical fiber at receiving terminal, not in lens focal plane position, also can meet with into the loss of light energy,Again increase the insertion loss of the joints of optical fibre.
And the present invention is directed to above-mentioned defect, and adopt said structure design, can effectively solve existing lens-typeFine high inconsistence problems between joints of optical fibre multi-core fiber, has avoided the insertion coupling being caused by optical fiber height to damageConsumption, has ensured the coupling efficiency between optical fiber and lens preferably, has reduced the insertion of whole connector scheme and has damagedConsumption. The present invention adopts technique scheme to change the optical fiber fixed form of the joints of optical fibre in the past and (adopted in the pastFix with front end), adopted rear end fixed solution (fixed form can adopt various ways, as glue is fixed,Grip etc.), front end optical fiber can be freely movable in the axial direction. When optical fiber is fixed, adopt fixed length mode,Ensure that optical fiber protrudes insertion core end face, when assembling, utilize lens that optical fiber is pushed up back, allow optical fiber the inner shape of connectorBecome bending shape, ensure fiber end face and the fine laminating in the lens back side, the present invention can simplify lens-type optical fiberThe packaging technology of connector and cost, between past lens and optical fiber conventionally because there being gap, and need specific foldingPenetrate the glue of rate and fill up the gap between lens and optical fiber, ensure the coupling loss between optical fiber and lens. AndThe present invention (is the Shi Qi focal plane, the back side that we suppose lens piece, when band fibre because adopt Microbend structures designAfter the optical fiber afterbody of one end is fixed, the naked fine end face of optical fiber one end is preset as higher than insertion core end face 0.2mm, dressWhile joining lens piece, lens toward pusher, utilize the bending stress of optical fiber body by optical fiber, can fiber end face is completeEntirely be attached at lens focal plane position, and then make light beam see through the parallel ejaculation of lens), between lens and optical fiberDistance does not have special requirement, and therefore the fixed form of lens just can adopt various ways, as gluing, buckleEtc. mode, do not repeat at this.
As another preferred embodiment, as shown in Fig. 5 a to 5d, a kind of joints of optical fibre as aboveThe assembly method of plug, specifically comprises the following steps:
A. described positioning and guiding PIN pin 22 is inserted in the counter sink 25 in described lock pin 21 two sides, one end;As a kind of preferred embodiment, the end face of the tail end of positioning and guiding PIN pin 22 exposes counter sink 25 slightlyThe end face of one end, so that be with fine fixture to be compressed. This structural design, with respect to positioning and guiding PINPin 22 and the integrated processing mode of lock pin 21, can be convenient assembly be processed, and makesThe installation accuracy that obtains positioning and guiding PIN pin 22 is higher.
B. the other end of fine described band keeper 31 is inserted in the draw-in groove 24 of described lock pin 21 other ends,And the positioning and guiding PIN pin 22 in end face and the described counter sink 25 of the other end of the fine keeper 31 of described bandEnd face inconsistent; As preferred embodiment, the bottom of draw-in groove is also provided with and is with fine keeper 31 bottom surfacesThe through hole that matches of locating dowel 34, this structural design, can effectively limit the free degree between the two, makesIt closely cooperates and forms an entirety, is convenient to both dismountings and with fine installation with this.
C. described lens 5 are assembled on the end face of described lock pin 21 one end; As preferred embodiment, thoroughlyThe two ends of mirror are provided with the locating hole matching with positioning and guiding PIN pin 22, and the medial surface of lens is coated withBe used for the glue fitting tightly with the end face of lock pin 21 one end, the surrounding of glue coating area offers the glue groove that overflows,So that unnecessary glue flows into the glue groove that overflows, and can not have influence on the outward appearance of other parts.
D. by fine the band that is arranged with gum cover 41 through the fine keeper 31 of described band, the one end that makes gum cover 4 withMatch in one end of the fine keeper 31 of described band; As a kind of preferred embodiment, with fine keeper 31On end face, offer the mounting groove matching with described gum cover, can be easily by gum cover be with fine keeper 31Be assembled together, the design of this structure, can reduce band fibre and with the stress between fine keeper, be convenient to bandFine is fixing.
As further preferred embodiment, naked fibre and described gathering sill after grind fine 1 end of described bandMatch to merge with microwell array 23 and make naked fibre expose to microwell array 23 end faces to push against described lens 5 inner sidesPlane, the band fibre 1 in described precise guiding device 2 is bent. And then make to be with fine end to grindEnd face and the lens focal plane of the naked fibre after mill are fully adjacent to.
E. the optical fiber of described optical fiber fixing groove 33 tops be assembled in optical fiber fixing groove 33 and use glue fastening,Then described cover plate is being installed with above described optical fiber fixing groove 33, and is making cover plate and be with fine keeper 31Firmly fixing.
As another preferred mounting means, at lock pin with after being with fine fixture to assemble, also can be first byMicrowell array on naked fibre and lock pin with fine one end matches to merge and makes its naked fine end face expose to the end face of lock pin0.2mm, then being assembled to the optical fiber above optical fiber fixing groove 33 in optical fiber fixing groove 33 and tight with glueGu, finally the lens of insertion core end face are installed again and are made its medial surface push against the end face that exposes naked fibre, insert makingThe fibre-optical bending of in-core, and then the end face of naked fibre and the medial surface of lens are fitted tightly.
By above-mentioned steps, can make optical fiber connector plug form an entirety, and can be accurately byBand is fine effectively fixing, and can make the naked fine end face at insertion core end face place and the medial surface of lens fully fit,Prevent from, because the fine high inconsistent receiving terminal that causes can not be coupled to optical signal in receiving terminal optical fiber completely, causingThe loss of optical signal. In addition, the optical fiber connector plug of installing by above-mentioned steps, with traditional by lightFine insertion in lock pin and by solidifying glue and lock pin is solidified togather, and then the front end of lock pin carried out to precision and grindsGrinding and polishing light is compared with the processing mode that reaches instructions for use, greatly reduces difficulty of processing, has reduced plugScrap, and then effectively reduce the production cost of plug.
Know-why of the present invention has below been described in conjunction with specific embodiments. These are described just in order to explain thisThe principle of invention, and can not be interpreted as by any way limiting the scope of the invention. Based on hereinExplain, those skilled in the art does not need to pay performing creative labour can associate other tool of the present inventionBody embodiment, within these modes all will fall into protection scope of the present invention.
