Background technology
At present, be used for the mode fixed fiber that the cold joint connector product of fiber alignment mainly adopts V-type groove and briquetting to compress, thereby the action of hold down gag is to reduce with the slit pressed fiber of V-type groove and realize two fiber alignments through pressing down briquetting; In this kind mode, the processing of V-type groove belongs to inside dimension, and size is minimum; Machining precision is difficult to control, and detection difficulty is big, causes the butt joint index to descend easily; And cost is higher; Need when wearing fibre V-type groove and briquetting are separated, wear and compress briquetting again, complex operation after fibre finishes.
Summary of the invention
What the present invention proposed is a kind of optic fibre clamp that is used for cold splice for optical fibers, and its purpose is intended to overcome the above-mentioned defective of existing in prior technology, adopts three pilot pins to be close to the space grip optical fiber of formation each other; Adopt three pins of part clamping such as V-type keeper; Broken through traditional structure, simple and reliable for structure, long service life; Reusable, cost is low.
Technical solution of the present invention: it is characterized in that comprising A, B, three pilot pins of C, described A, B, three pilot pins of C are each other near forming the optical fiber through hole; The pressing plate and the V-type keeper that are positioned in the pedestal draw-in groove form positioning chamber, and A, B, three pilot pins of C are placed in this positioning chamber, and A pilot pin, the B pilot pin in A, B, three pilot pins of C is clamped in four elastic arms in the V-type keeper; The steel ball that is positioned in the pedestal pilot hole withstands the C pilot pin in A, B, three pilot pins of C; The bracelet reed clamps pressing plate and pedestal from a side of pressing plate and pedestal, and the plectrum of bracelet reed compresses steel ball simultaneously, and reed with holes clamps pressing plate and pedestal from the opposite side of pressing plate and pedestal, and the optical fiber that penetrates is fixed in the optical fiber through hole.
The present invention compared with prior art has following advantage: 1) the present invention breaks through the structure of the fixing butt joint of traditional V-type groove optical fiber; Adopt three pilot pins to be close to the space grip optical fiber of formation each other, simple in structure, easy to process; Precision is easy to control and detects, and manufacturing cost reduces greatly.2) the present invention is in wearing fine process, and there are adaptive process in three pilot pins and optical fiber, need not manually to split structure, promptly recover tightening state after fibre to be worn puts in place, and simple to operate, merging precision is high.3) the formed optical fiber through hole of three pilot pins of the present invention is except that the space of receiving optical fiber, also has three subtriangular spaces, and the optical fiber matching fluid that is extruded in the time of can be for fiber alignment provides the deposit space.4) pilot pin of the present invention adopts the non-corrosive material manufacturing, and reliable in structure is not subject to factor affecting connecting qualities such as temperature variation, material aging, long service life.
