Description

Technical Field

[0001] This utility model relates to the field of optical fiber connection technology, and more specifically, it relates to a clamp for an optical fiber fusion splicer. Background Technology

[0002] In existing fiber optic fusion splicing equipment, fiber optic clamps generally employ simple spring clips or V-groove clamping structures. Initial fixation is achieved by using the clamping force generated by elastic elements or gravity to press the fiber onto the clamping surface. However, this simple clamping method suffers from significant instability. Unstable clamping can cause the fiber end faces to shift during alignment, directly affecting the coaxiality of the two fiber axes and the consistency of the end face gap, ultimately leading to increased splicing loss or even splicing failure. Existing clamps typically use a flat or simple V-shaped surface design for the clamping surface, which is incompatible with the fiber... The contact of the cylindrical outer surface is a line contact or point contact. The small contact area leads to pressure concentration, which can easily damage the optical fiber and make it difficult to provide sufficient friction to achieve reliable fixation. The optical fiber may still slip axially or rotate radially while in the clamped state, which cannot meet the strict requirements of the fusion splicing process for precise alignment and stable maintenance of the optical fiber end face. At the same time, the existing optical fiber fusion splicer clamps also have certain shortcomings in terms of ease of operation. The clamping and unclamping process of optical fiber usually requires multiple manual operations by the operator, resulting in low overall work efficiency when facing a large number of optical fiber splicing tasks. Utility Model Content

[0003] (a) Technical problems to be solved In view of the problems existing in the prior art, this utility model provides a fixture for an optical fiber fusion splicer to solve the technical problems mentioned in the background art.

[0004] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A fixture for an optical fiber fusion splicer includes a mounting rod with a placement groove; it also includes a clamping mechanism, which includes mounting plates. Four sets of mounting plates are provided on the end face of the mounting rod. A first rotating shaft is rotatably connected between two sets of mounting plates on one side, and a second rotating shaft is rotatably connected between two sets of mounting plates on the other side. Two sets of first rotating plates are fixedly sleeved on the first rotating shaft, and a first connecting rod connects the two sets of first rotating plates. Two sets of second rotating plates are fixedly sleeved on the second rotating shaft, and a second connecting rod connects the two sets of second rotating plates.

[0005] Preferably, a first clamp is fitted onto the first rotating shaft and the first connecting rod. The inner side wall of the first clamp has a first clamping groove, and the outer side wall of the first clamp has two sets of fixing holes. The design of the first clamp fitted onto the first rotating shaft and the first connecting rod realizes reliable transmission that allows the clamp to rotate synchronously with the rotating shaft.

[0006] Preferably, a second clamp is fitted on the second rotating shaft and the second connecting rod, and a second clamping groove is opened on the inner side wall of the second clamp. The second clamping groove is used in conjunction with the first clamping groove. Through the symmetrical arrangement of the second clamp and the first clamp and the cooperation of the second clamping groove and the first clamping groove, the optical fiber is clamped in a double-sided ring-shaped manner.

[0007] Preferably, the outer wall of the second clamp is provided with two sets of limiting cylinders, and two sets of fixing rods are slidably connected inside the two sets of limiting cylinders. The two sets of fixing rods are connected by push rods, and the fixing rods are adapted to the fixing holes. The locking mechanism design, which drives the two sets of fixing rods to be inserted into the corresponding fixing holes simultaneously by push rods, realizes the fast and reliable locking and convenient release of the clamp in the closed state.

[0008] Preferably, a first follower plate is fixedly sleeved at the end of the first rotating shaft, and a first connecting block is rotatably connected to the other end of the first follower plate. The rotational motion of the first rotating shaft is transmitted to the first connecting block through the first follower plate, thereby realizing the effective conversion of rotational motion into linkage mechanism.

[0009] Preferably, a second follower plate is fixedly sleeved at the end of the second rotating shaft, and a second connecting block is rotatably connected to the other end of the second follower plate. The motion of the linkage mechanism is transmitted to the second rotating shaft through the second follower plate, thereby realizing the reverse synchronous rotation of the second rotating shaft and the first rotating shaft.

[0010] Preferably, a first threaded rod is fixedly connected inside the first connecting block, and a second threaded rod is fixedly connected inside the second connecting block. A bidirectional threaded cylinder is provided between the first threaded rod and the second threaded rod. The threads at both ends of the bidirectional threaded cylinder are in opposite directions. The other end of the first threaded rod is threadedly connected to one end of the inner side of the bidirectional threaded cylinder, and the other end of the second threaded rod is threadedly connected to the other end of the inner side of the bidirectional threaded cylinder. Through the cooperation of the reverse threads at both ends of the inner side of the bidirectional threaded cylinder with the first and second threaded rods, the linkage effect of driving both clamps to rotate synchronously in opposite directions by pushing either side of the clamp is achieved.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a clamp for an optical fiber fusion splicer, which has the following beneficial effects: The clamp for an optical fiber fusion splicer provided by this utility model solves the problems of unstable optical fiber clamping and inconvenient loading and unloading in the prior art through the clamping mechanism. Specifically, through the reverse linkage rotation of the first and second rotating shafts and the mating clamping design of the first and second clamps, the synchronous closing and uniform clamping of both sides of the optical fiber is realized. The cooperation of the first and second clamping slots provides a stable, circumferential clamping surface for the optical fiber. Compared with traditional planar or simple V-groove clamping, it increases the effective contact area with the optical fiber, transforms point contact or line contact into surface contact, and reduces the pressure per unit area. This avoids mechanical damage to the optical fiber coating and bare fiber, and provides a reliable fixing effect through a larger contact area and friction. It effectively prevents the optical fiber from axially slipping or radially rotating in the clamping state, ensures the positional stability of the optical fiber end face during the fusion alignment process, and improves the fusion quality and success rate.

[0012] The design of the bidirectional threaded cylinder, combined with the first and second threaded rods, enables reverse linkage transmission between the first and second rotating shafts. Operators only need to push either the first or second clamp to drive both clamps to rotate synchronously in opposite directions and clamp the optical fiber. The entire clamping action is completed in one smooth motion without step-by-step operation, simplifying the optical fiber clamping process and reducing the skill level and hand movements required of operators. This effectively avoids optical fiber damage and splicing failure caused by improper operation of traditional clamps. The synchronous closing design ensures that the clamping force applied to the optical fiber by both clamps remains balanced and symmetrical, avoiding optical fiber offset or bending deformation caused by unilateral force, further guaranteeing the accuracy of optical fiber end face alignment and the quality stability of the splice. The locking mechanism of the fixing rod, fixing hole, and push rod provides reliable mechanical locking for the closed state of the clamps. After the first and second clamps are closed in place, pushing the push rod inserts the fixing rod into the fixing hole, firmly locking the clamps in the clamping position and effectively preventing the clamps from loosening due to external vibration or accidental contact during the splicing process.

[0018] Please see Figures 1-5A fixture for an optical fiber fusion splicer includes a mounting rod 11 with a placement groove 12; it also includes a clamping mechanism, which includes mounting plates 21. Four sets of mounting plates 21 are provided on the end face of the mounting rod 11. A first rotating shaft 22 is rotatably connected between two sets of mounting plates 21 on one side, and a second rotating shaft 23 is rotatably connected between two sets of mounting plates 21 on the other side. Two sets of first rotating plates 24 are fixedly sleeved on the first rotating shaft 22, and a first connecting rod 25 connects the two sets of first rotating plates 24. Two sets of second rotating plates 26 are fixedly sleeved on shaft 23, and a second connecting rod 27 is connected between the two sets of second rotating plates 26. A first clamp 28 is sleeved on the first rotating shaft 22 and the first connecting rod 25. A first clamping groove 29 is formed on the inner side wall of the first clamp 28, and two sets of fixing holes 210 are formed on the outer side wall of the first clamp 28. A second clamp 211 is sleeved on the second rotating shaft 23 and the second connecting rod 27. A second clamping groove 212 is formed on the inner side wall of the second clamp 211, and the second clamping groove 212 cooperates with the first clamping groove 29 to... The second clamp 211 has two sets of limiting cylinders 213 on its outer side wall. Two sets of fixing rods 214 are slidably connected inside the two sets of limiting cylinders 213. The two sets of fixing rods 214 are connected by a push rod 215. The fixing rods 214 are adapted to the fixing holes 210. A first follower plate 216 is fixedly sleeved at the end of the first rotating shaft 22. A first connecting block 217 is rotatably connected to the other end of the first follower plate 216. A second follower plate 218 is fixedly sleeved at the end of the second rotating shaft 23. The other end of the second follower plate 218 is rotatably connected to... A second connecting block 219 is connected. A first threaded rod 220 is fixedly connected inside the first connecting block 217. A second threaded rod 221 is fixedly connected inside the second connecting block 219. A bidirectional threaded cylinder 222 is provided between the first threaded rod 220 and the second threaded rod 221. The threads at both ends of the bidirectional threaded cylinder 222 are in opposite directions. The other end of the first threaded rod 220 is threaded to one end of the bidirectional threaded cylinder 222, and the other end of the second threaded rod 221 is threaded to the other end of the bidirectional threaded cylinder 222.

[0019] In this invention, the clamping mechanism enables convenient clamping and disassembly of optical fibers. This clamping device requires two symmetrically arranged sets. Taking one side as an example, specifically, the optical fiber to be spliced ​​is placed in the placement slot 12, with the splice end of the fiber positioned between the first clamp 28 and the second clamp 211. Then, the operator can manually push the first clamp 28 or the second clamp 211 to rotate it towards the optical fiber. If the first clamp 28 is pushed, it will cause the first rotating shaft 22 to rotate along the mounting plate 21. The first follower plate 216 rotates with the first rotating shaft 22, and the first follower plate 216 will in turn cause the first connecting block 217 to rotate. The first connecting block 217, through the first threaded rod 220, the bidirectional threaded cylinder 222, and the second threaded rod 221, drives the first connecting block 217 to rotate. When the second connecting block 219 rotates, the second connecting block 219 will drive the second rotating shaft 23 to rotate through the second follower plate 218. At this time, the rotation direction of the second rotating shaft 23 is opposite to the rotation direction of the first rotating shaft 22. The second rotating shaft 23 will drive the second clamp 211 to rotate in the direction of the optical fiber, so that the first clamp 28 and the second clamp 211 rotate in opposite directions and close together. The inner sidewalls of the first clamp 28 and the second clamp 211 gradually fit together until they are horizontal. At this time, the optical fiber is inserted into the first clamping groove 29 and the second clamping groove 212 to achieve clamping and fixation. Afterwards, the staff can manually push the push rod 215 to insert the two sets of fixing rods 214 into the corresponding fixing holes 210, thereby fixing the position of the first clamp 28 and the second clamp 211. The clamping devices on both sides are set up in this way. Then the fusion splicing of the optical fibers on both sides can begin. When the optical fiber needs to be disassembled after the splicing is completed, the operator manually pushes the push rod 215 so that the push rod 215 drives the two sets of fixing rods 214 to slide along the limiting cylinder 213 until they are disengaged from the fixing hole 210. At this time, the first clamp 28 is manually lifted, and the first clamp 28 drives the first rotating shaft 22 to rotate in the opposite direction. The first rotating shaft 22 drives the second rotating shaft 23 to rotate in the opposite direction through the first follower plate 216, the first connecting block 217, the first threaded rod 220, the bidirectional threaded cylinder 222, the second threaded rod 221, the second connecting block 219, and the second follower plate 218. This drives the second clamp 211 to be lifted synchronously, and the clamping of the optical fiber can be released, so that the optical fiber can be disassembled. By rotating the bidirectional threaded cylinder 222, the first threaded rod 220 and the second threaded rod 221 can be driven to move in opposite directions, thereby adjusting the distance between the first connecting block 217 and the second connecting block 219, and thus adjusting the opening and closing angle of the first clamp 28 and the second clamp 211.
