Abstract
An optical fiber connector consists of a base and three V-shape slots fixed on the base, which is used for containing reference optical fiber and tested optical fiber. Three concave plates with a concave surface oriented to the front head face of the base are fixed on the base, the rear part of a pressure pad is inserted into the concave positions of the concave plates, and the concave plates and the pressure pad are connected by three axes running through the right side of the concave plates. The pressure pad is provided with screwed holes, and the pressure pad, a spring, and a pressure block are connected together by bolts, the optical fiber is tightly pressed at the lower end surface of the pressure pad. A front nest pin and a back nest pin respectively screwed in the screwed holes in the front and back head faces of the base are used for adjusting the travel route of the pressure pad. The optical fiber connector is characterized by rapid connection, long service life, easy maintenance, and reliably fixing the tested optical fiber.
Description
Technical field
The present invention relates to a kind of joints of optical fibre, particularly a kind of free fiber-optics connector that has three V-type groove structures.
Background technology
Along with the Optical Fiber Transmission application is growing, concerning installation, maintenance, test light waveguide line person and the makers' reviewer of optical fiber cable, need dock optical fiber continually.The joints of optical fibre adopt the fine metal of internal diameter, pottery, rubber or glass tube to hold reference and tested optical fiber usually.Fig. 1 is the synoptic diagram that the active type joints of optical fibre major part of present widespread use connects optical fiber, among the figure, 2 is above-mentioned described glass tube, and during butt joint optical fiber, coat 11 is peelled off with the front end of left optical fiber 1 by general elder generation, only allow bare fibre 12 extend into certain A in the glass tube then, then right optical fiber 3 is in kind removed coat 31, bare fibre 32 is stretched in the glass tube 2, until arriving the A point, dock with left side bare fibre 12, finish the coupling of light signal.These type of joints of optical fibre need accurate processing for connecting pipe; Optical fiber is generally very crisp, and quartz glass optical fiber very easily ruptures, and in a single day optical fiber break in the pipe, and extremely the difficulty optical fiber that will break takes out, and often influence connects test, even incurs loss through delay the duration.Again,, can only hold glass tube by hand usually, therefore, be unsuitable for quick test because of such fibre-optic connector structure is too fine, and fixing unreliable for optical fiber.
Summary of the invention
The object of the present invention is to provide a kind of joints of optical fibre, but this kind joints of optical fibre rapid connection, long service life, be easy to safeguard, characteristics that can the secure fixation tested optical fiber.
For realizing purpose of the present invention, a kind of joints of optical fibre that the present invention discloses comprise a base, and this forward end of base upper bottom surface is fixed with three the V-type grooves in left, center, right, and left and right sides V-type groove is identical, about be different with the V-type groove of centre; These three V-type grooves are used to accommodate reference optical fiber and tested optical fiber; Lean on the rear end face place at the base upper bottom surface, be fixed with three blocks of matrix plates, the concave surface of matrix plate is towards the front end face of base, the rear end part of pressing plate is inserted the recess of matrix plate, three axles by matrix plate right flank are connected three blocks of matrix plates respectively with three block pressur plates, the upper surface of pressing plate is provided with a threaded hole near the front end face place, and the briquetting that screw is adjusted spring with pressing plate, the optical fiber compaction degree that is arranged in the pressing plate groove downwards and is positioned at the spring below links together; The pressing plate groove is positioned at the top of V-type groove.Briquetting lower surface pressed fiber is screwed in the stroke that forward and backward register pin on the base front/rear end threaded hole is used for regulating pressing plate.
The reference optical fiber that will have coat is inserted in the V-type groove of a side, the naked fine part of this optical fiber is put into the nearly middle part of middle V-type groove, depress the pressing plate of above-mentioned placement band coat reference optical fiber top, the tested optical fiber fore-end is removed coat, the naked fibre of tested optical fiber is put into middle V-type groove, its front end face is contacted with the front end face of reference optical fiber, tested optical fiber is had coat to be disposed into opposite side V-type groove, then the pressing plate of centre and the pressing plate of opposite side are depressed, guarantee that optical fiber is pushed down, promptly finished the mating operation of optical fiber.Above-mentioned described V-type groove, three lines of three V-shape bottoms are on same straight line.The stroke of pressing plate is controlled by the register pin that passes base front end face and rear end face, and prelocalization pin, back register pin are positioned at the both sides, front and back of pressing plate; Because the effect of magnetic, register pin, pressing plate can attract each other.
Compared with prior art,, do not need repeatedly to connect, dock efficient with improving so can accelerate butt joint speed greatly because of after reference optical fiber fixedly finishes; Again, be positioned at the base top owing to be used for the V-type groove of fiber alignment, the optical fiber in the V-type groove is visible, so be very easy to safeguard and change; Again, the V-type groove of both sides is to design for fixed fiber specially, so more reliable to fixing of optical fiber.
