Background technique

General mechanical optical fiber splices (Mechanical Optical Fiber Splice) are used for the connection of two optical fibers to continue the transmission of optical signals, usually including two parts such as the fiber fixing part and the fiber clothing (or fiber sheath) fixing part. Please refer to Fig. 1, which is the "mechanical optical fiber splice" patent case of the United States (US) No. 4,730,892. It can be seen that a splice 10 uses a central screw 11 to lock the optical fiber fixing part 12, and a longitudinal The rotating wheel 13 and a horizontal rotating wheel 14 carry out the locking of the two fiber clothes fixing parts 15, 16 respectively, because a screwdriver and fingers are used to stir, so there is a risk of insufficient convenience.

Please refer to Fig. 2, which is the U.S. No. 5,042,902 "Optical Fiber Splice and Method of Use" patent case, it can be seen that a splice 20 utilizes a capillary 21 to incorporate two optical fibers 22, 23, and is connected by an upper fixture 24 and the lower fixing part 25 are clamped to form two fiber clothing fixing parts 26,27, because there is a considerable gap between the channel 28 in the capillary 21 and the optical fibers 22,23, so its optical fibers 22,23 are not Direct fixation has the disadvantage of insufficient stability.

Please refer to Fig. 3, which is the U.S. No. 5,220,630 "Fiber Three Rod Connector (Connector) with a Rod (Rod) Urgent Clamp" patent case, it can be seen that a connector 30 with clamping elasticity, its Utilize three slender round rods 31, 32, 33 to fix the optical fiber 34, and by the intermediate space formed by the three round rods 31, 32, 33 to naturally obtain the optical fiber fixing part 35, because only the fixed optical fiber 34 cannot be fixed Its thin clothes, so its stability is still insufficient.

See also Fig. 4, and it is U.S. No. 5,638,477 " the tightening loosening device of optical fiber connection subcomponent and the improved tool of making this connection " patent case, it can be seen that a connection 40, it must first insert a piece (insert) 41 is placed in the base 42 and then utilizes the relative grooves (Grooves) 45 of the two parallel plates 441 and 442 of a clip member 43, and a parallel groove 46 and the central wall 47 at the lower part of the base 41 to form The cable receiving groove (Channel) or opening (Opening) 48 is used to receive the cable end (Cable end) with the fiber jacket, and by pushing the clip member 41 from top to bottom to obtain the effect of fixing the fiber jacket, due to its structure It is complicated and only fixes the fiber jacket but not directly fixes the optical fiber, which also has the disadvantage of insufficient stability.

Please refer to Fig. 5, which is the U.S. No. 5,708,746 "Rail Type Device for Mechanical Optical Fiber Splice" patent case, a splice 50 can be seen, which utilizes a bottom central protrusion of a longitudinal base plate 51 and a covering clamp 52 521 and two bottoms 531 of the two covering clamps 53 to preliminarily suppress 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 a top central protrusion 522 of the covering clamp 52 At the same time, the top protrusion 532 of the covering clamp 53 and the pair of top side wing protrusions 523 of the covering clamp 52 are pressed at the same time, thereby fixing the optical fiber 55. Since its structure is complicated and only the fixing optical fiber 55 fails to fix its fiber clothing, so its stability is also in danger of being insufficient.

Please refer to Fig. 6, which is the U.S. No. 5,963,699 "Mechanical Optical Fiber Splicer" patent case. It can be seen that a splicer 60 utilizes an intermediate cover plate 62 positioned on the top of the base member 61 and two end caps configured in a straight line 63 to preliminarily suppress two bare optical fibers 64 and a single optical fiber 65 with fiber clothing respectively, and utilize a positioning protrusion 67 of an elastic long and thin clamp 66 to clamp one of the middle cover plate 62 and the end cover 63 A corresponding concave portion (not shown) corresponding to the concave portion 68 and the base member 61 is used to press the base component 61, the middle cover plate 62 and the two end caps 63 to fix the bare optical fiber 64 and the fiber clothing fiber 65. It only uses the metal elasticity of the clamp 66 to fix the optical fiber 34 and its fiber jacket, so after long-term use, it will inevitably suffer from elastic fatigue and cannot continue to clamp strongly.

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 shortcoming of the elastic fatigue of metal clamps, the mechanical optical fiber connector can also obtain the convenience of fast fixing of the optical fiber 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.
