Description
The present invention relates to a kind of optical-fibre communications, photoelectric sensor, single-mode fiber coupling apparatus makes laser output to accurate location of optical fiber input and directed micromatic setting, (claiming coupling mechanism or title fiber alignment device), also can make optical-fiber laser welding coupling mechanism and use.
" photoelectric sensor " of at present domestic and international development and Application, its can be under High Temperature High Pressure high voltage magnetic field interference-free And operate as normal, detect signal directly by same Optical Fiber Transmission with photoelectric sensor, reach the unification of transmission data and output signal, micromatic setting then is the indispensable device of optical communication photoelectric sensor.The micromatic setting that the U.S. new lane company puts on display in Shanghai International Exhibition Centre on October 30th, 1986 to November 6; the amount trimmed precision of the X of level, Y direction and vertical Z direction is the 1-2um level; the SO-2A type micromatic setting that Shanghai machine maintenance device factory produces; X, Y, Z trimming precision are 1～2 μ m level; 23 import Japan NEC of ministry of electronics industry electric corporation, 0.1 μ m optical fiber micromatic setting, but do not reach 0.1 μ m class precision (now to the claim of NBC electric corporation) through the reality debugging.
Micromatic setting vertical direction that the U.S. new lane company and Shanghai machine maintenance device factory produce and horizontal direction are respectively with a 4mm screw adjusted; screw and internal thread diameter are 4mm; because of the contact area of this structure screw thread little; be adjusted to 1～3 μ m precision; operating difficulties; and be difficult for self-locking; when on Switzerland TESA company production inductance amesdial, measuring; produce dancing; after treating that the beat of pointer is stable, just can read precise number, so when single-mode fiber (5～10 μ m core diameter) is coupled; the micromatic setting of producing both at home and abroad all can not satisfy the coupling precision at present.
The purpose of this utility model provides that price is low, feel is light, fine setting is stable, and self-locking property is good, and trimming precision can reach the micromatic setting that 0.1 μ m Ji ， And can satisfy modern optical communication single-mode fiber coupling usefulness.
The utility model is to realize like this.
The utility model comprises: to governor motion, one group of Y is to governor motion to governor motion, one group of Z for fixed head, deckle board, one group of X.
Fixed head has two set screw on the diagonal line at the center of mistake, itself and the close auxiliary tone of screw save, the top is connected with location, deckle board " V " type relevant position with steel ball, and fixed head has a center pit, does not collide mutually when guaranteeing to regulate, threaded hole is arranged around the fixed head, can supply fixedly usefulness, the centre bit that connects deckle board in corresponding street is equipped with a plug, and optical fiber is packed into behind the plug, be pressed into plug fluting center with compressing tablet then, play the fixed fiber effect.Plug is horizontal goes here and there in the center of fixed head and deckle board And under the slide block and spring action on the deckle board, plug can be in certain position, on the fixed head three cover regulating part, the horizontal Y direction position of calibration deckle board and plug, prevent before and after the deckle board simultaneously and tilt, in the deckle board vertical direction is that Z has one group of mechanism that regulates plug on the position, two set screw of the vertical installation in deckle board upper end, the steel ball of screw head, respectively with the stock of press-down type double lever: quarter butt point contacts, and near the quarter butt place one eccentric pillar is arranged, near the stock place one back-moving spring is arranged, according to press-down type double lever principle, thereby make two groups of regulating parts bear the Z axle X-axis fine setting of plug and the task of coarse adjustment respectively, injection has the meticulous oil of certain viscosity between regulating part, under the lever moment effect, owing to adopted the way of indirect transfer moment, eliminated the cumulative errors of transmitting, when therefore finely tuning, reliable and stable, self-locking property is strong.
Deckle board horizontal direction X on the position, have one group with Z to identical governor motion, regulate the direction difference exactly.
X, the Z set screw in governor motion has adopted screw diameter greater than 4mm, under the constant situation of pitch, reduced lead angle, also just increased the contact area of screw thread, about 30 ° of the every rotation of micrometer adjusting screw then is the 0.1 μ m fine setting amount of feeding, the no big phenomenon that swings, backhaul is minimum, has reached reliable and stable and the self-locking purpose.
X, Z micrometer adjusting screw and dual lever mechanism not only are applied in the fiber coupler, also are widely used in simultaneously on precision machine tool micro-adjusting mechanism and the measurement apparatus.
Advantage of the present utility model:
1. when laser output power is coupled with 0.1 μ m high precision micromatic setting, except refraction and reflection loss, reach full performance power coupling substantially.
2. optical communication single-mode fiber 5～10 μ m diameter core diameters coupling with 0.1 μ m level optical fiber micromatic setting, has been satisfied actual needs.
3. cost simple in structure is low, reaches the purpose of high precision fine setting, self-locking, and cost is 1/100 import price.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a stereographic map of the present utility model.
Fig. 2 is a dual lever mechanism synoptic diagram of the present utility model.
Fig. 3 is that the utility model is crossed plug 7 central cross-sectional view.
