Description
Technical field
The present invention relates to the optical fiber locking device in the fiber active linker, be meant that specifically being used for precision positioning in the fiber active linker plug connects contact pin, the contact pin micropore is inserted in the termination of guiding fiber, the optical fiber that is locked makes a kind of micropore guiding of optical-fibre precise centering link light path purposes close the optical fiber locker of symbol structure.
Background technology
Contact pin is the element that is used as optical-fibre precise centering in the fiber active linker plug, and contact pin is the right cylinder that the center is provided with a circular micropore, and the making material of contact pin has stainless steel, pottery, glass and plastics several; The code requirement of contact pin is high, and the precision of the offset of micropore has especially directly determined the light scattering and the light decrement of light path link place; For example, the code requirement of full ceramic contact pin is as follows: external diameter Φ 2.499 ± 0.0005mm; External diameter out-of-roundness＜0.0005mm; Micro-pore diameter Φ 0.126mm ± 0.5 μ m; Micropore offset＜1 μ m; Micropore degree of depth 4mm or 10mm; Contact pin exterior circular column smooth finish
14; End face radius-of-curvature 20-60mm.Contact pin and optical fiber, and contact pin need be connected by the transition of optical fiber locker with the flexible jumper plug, therefore, except the precision of contact pin self, the precision of optical fiber locker has also determined the light scattering and the light decrement of light path link place.
The optical fiber locker of prior art be plastics make by the front portion, the middle part, the perforation clamp device that rear portion three grades of step right cylinders one constitutes, consult Fig. 8, Fig. 9, the front end center of its anterior large cylinder step is provided with the blind hole of a location contact pin, the Geometrical Tolerance Principle of blind hole is identical with contact pin, and dimensional requirement and contact pin interference fit, the bottom of blind hole is provided with semicircular through hole and communicates with the plane of the semicylinder at middle part, the central axis on the plane of the semicylinder at middle part is provided with optical fiber and cooperates, radius is R0.063mm ± 0.25 μ m, central recess with the circular section of the offset＜1 μ m of blind hole axis, the top of central recess is provided with a jig arm, and the through hole that small cylinder step center, rear portion is provided with a guiding purposes communicates with the central recess on the semicylinder plane at middle part; During application, contact pin inserts in the blind hole fixing, optic fibre end passes the center bullport of rear portion small cylinder step, through the central recess on the semicylinder plane, middle part, the semi-circular through hole of passing anterior large cylinder step pierces in the micropore of contact pin, and optic fibre end is concordant with the outlet of contact pin micropore, with glue optic fibre end is fixed on the contact pin, simultaneously, be pressed in the central recess optical fiber fixing with tightening up cover by the jig arm that is located at semicylinder planar central groove top, middle part.
The formed precision of optical fiber locker has determined the positional precision of the contact pin that carried, the bearing accuracy of optical fiber locker then relies on the precision of the slide block of loosing core of the injection mold that makes it moulding, because the slide block of loosing core of moulding optical fiber locker must be taken into account above-mentioned central blind hole, semi-circular through hole, central recess, the moulding of jig arm is loosed core, the body of slide block is extremely tiny and long so loose core, during injection mo(u)lding, under the effect that the plastic liquid of fusion impacts, easily be offset, cause the bearing accuracy of optical fiber locker to be affected, finally cause the optic fibre end offset to exceed standard, the fraction defective height of optical fiber locker goods during large-scale production; In addition, when using assembling, superfine optic fibre end need pass through the center bullport at above-mentioned optical fiber locker rear portion and enter the micropore of contact pin through the central recess at middle part, anterior semi-circular through hole, so wear the optical fiber inconvenience, make efficiency of assembling low, labour cost occupies high; Therefore, prior art exists goods fraction defective height, efficiency of assembling is low, cost is high problems and shortcomings.
Summary of the invention
Problems and shortcomings at above-mentioned prior art existence, the present invention adopts serve as reasons first slit bamboo or chopped wood, second slit bamboo or chopped wood two and half slit bamboo or chopped wood cylinder step body amalgamations of optical fiber locker branch is closed the symbol structure, the locker termination integral body of decision contact pin offset index is arranged on the front portion of second slit bamboo or chopped wood, be connected as a single entity with the middle part of second slit bamboo or chopped wood and the half slit bamboo or chopped wood cylinder step body at rear portion, be provided for the central blind hole of precision positioning fixing plug pin at the front end center of locker termination, pierce into the center guiding micropore of contact pin in bottom centre's setting of central blind hole in order to the precision of guiding fiber; During application, fixing in the central blind hole of contact pin interference insertion locker termination, first slit bamboo or chopped wood links together with the corresponding amalgamation of second slit bamboo or chopped wood, optical fiber pierces into from the guide line hole that the corresponding amalgamation with second slit bamboo or chopped wood of first slit bamboo or chopped wood forms, and the micropore glue that inserts the contact pin that is arranged in locker termination central blind hole through the center of centerline hole and second slit bamboo or chopped wood guiding micropore is solid; Utilize the guiding of center guiding micropore, make things convenient for optic fibre end to insert the micropore of contact pin, the weak point that the slide block of loosing core that utilization divides the slit bamboo or chopped wood moulding to make moulding central blind hole and center guiding micropore can be done and sturdy, the impact of the molten stream of plastics during with the opposing injection mo(u)lding, guarantee the technical scheme of central blind hole formed precision, provide a kind of micropore guiding to close the optical fiber locker of symbol structure, be intended to close the symbol structure and make the production of plastic connector pin and application reach the purpose that improves job efficiency, improves efficiency of assembling, reduces cost by guiding micropore and amalgamation.
