Wedge-type mechanical optical fiber splicer

Abstract

The invention relates to a wedge-type mechanical optical fiber splicer which comprises a shell, a V-shaped groove block, a pressing block and a first wedge, wherein two ends of the shell are provided with tubes with optical fiber guide holes; the V-shaped groove block is a first strip block, and the surface of the first strip block is provided with a V-shaped groove; the pressing block is a second strip block; and the first wedge is a blocky object with an inclined angle. The pressing block is pushed to the V-shaped block through the first wedge or the V-shaped groove block is pushed to the pressing block, so that two optical fibers in the V-shaped groove block can be aligned and closely fixed into the V-shaped groove block, and the effects of high tensile strength, simpleness and convenience for alignment, and the like can be achieved.

Description

technical field [0001] The present invention relates to a wedge-type mechanical optical fiber connector, in particular to a wedge-aligned and tightly fixed two optical fibers in a V-groove block to achieve high tensile strength and easy alignment. Fiber optic connectors. Background technique [0002] A general mechanical optical fiber splice (Mechanical Optical Fiber Splice) is used to connect two optical fibers to continue the transmission of optical signals, and usually includes two parts such as a fiber fixing part and a fiber jacket (or fiber sheath) fixing part. see figure 1 , which is the U.S. (US) No. 4,730,892 "Mechanical Optical Fiber Splicer" patent case, it can be seen that a splicer 10 uses a central screw 11 to lock the optical fiber fixing part 12, and through a longitudinal wheel 13 and One horizontal rotating wheel 14 carries out the locking of two fiber clothes fixing parts 15,16 respectively, owing to will use screwdriver and finger to stir, therefore qui...

Problems solved by technology

[0005] see Figure 4 , which is the U.S. No. 5,638,477 "Fiber Optic Splicing Subcomponent Compression Release Device and Improved Tool for Making the Splicing Sub" patent case, it can be seen that a splicing sub 40, it must first place an insert (insert) 41 into the base 42 and then utilize the opposite grooves (Grooves) 45 of two parallel plates 441, 442 of a clip member 43, and the cable reception formed by a parallel groove 46 at the lower part of the base 41 and the central wall 47. Groove (Channel) or opening (Opening) 48 is used to receive the cable end (Cable end) that has fiber clothing, and by pushing the clip member 41 from top to bottom to achieve the effect of fixing the fiber clothing, because its structure is complex and only fixed The fiber cannot be directly fixed by fiber clothing, which also has the disadvantage of insufficient stability

[0006] see Figure 5 , which is the U.S. No. 5,708,746 "Guide rail device for mechanical optical fiber splice" patent case, it can be seen that a splice 50 utilizes a bottom central protrusion 521 of a longitudinal base plate 51 and a covering clamp 52 and two Cover the two bottoms 531 of the clamp 53 to preliminarily press the optical fiber 55. When the cover plate 57 with the guide rail 56 slides along the track groove 59 of the longitudinal body 58 to the side of a top central protrusion 522 of the cladding clamp 52, that is, at the same time Then press the top projection 532 of the cover clamp 53 and a pair of top side wing projections 523 of the cover clamp 52 to fix the optical fiber 55. Because its structure is complicated and only the fixed optical fiber 55 can not fix its fiber clothing, so its There is also a risk of insufficient stability

[0007] see Image 6 , which is the U.S. No. 5,963,699 "Mechanical Optical Fiber Splicer" patent case. It can be seen that a splicer 60 uses an intermediate cover plate 62 above the base member 61 and two end caps 63 configured in a straight line to initially Squeeze two bare optical fibers 64 and a single optical fiber 65 with a fiber jacket, and use a positioning protrusion 67 of an elastic long and thin clamp 66 to clamp a corresponding concave portion 68 of the middle cover plate 62 and the end cover 63 A corresponding concave portion (not shown) of the base member 61 is used to press the base member 61, the middle cover plate 62 and the two end caps 63 to fix the bare optical fiber 64 and the fiber optic fiber 65. The metal elasticity of the clamp 66 is used to fix the optical fiber 34 and its fiber jacket, so after long-term use, it will inevitably have the disadvantage of elastic fatigue and cannot continue to clamp strongly

[0008] Therefore, how to improve the problem that the optical fiber fixing part and the fiber clothing fixing part of the optical fiber connector are not easy to be clamped strongly for a long time, the present invention aims at the above-mentioned deficiency. In addition to effectively solving the shortcomings of the elastic fatigue of metal clamps, the mechanical fiber optic connector can also obtain the convenience of fast fixing of the fiber optic connector

That is to say, the problem to be solved by the present invention is how to overcome the problem that the base member and the cover plate are not easily clamped by force for a long time, and how to overcome the problem that the adjacent pressing blocks are not easy to cooperate with each other only because of the oblique angle of the first wedge With the problem of tight clamping, how to overcome the problem of only tightly fixing the optical fiber but not tightly fixing the fiber clothing, etc.
