Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber fusion splicers, in particular to an optical fiber fusion splicer with an adjustable core. Background Art

[0002] Fiber fusion splicers are mainly used for the construction and maintenance of optical cables in optical communications. Before fusing the optical fibers, the fiber fusion splicer uses an imaging mechanism and a core alignment mechanism to align the ends of the two optical fibers in the same straight line. The high-voltage discharge mechanism is used to melt the two optical fiber sections, and a high-precision optical fiber advancement mechanism is used to smoothly advance the two optical fibers into one, so as to achieve the coupling of the optical fiber mode field; Patent No. CN202222770085.4 discloses a high-precision optical fiber fusion splicer with an adjustable core. Through the setting of the clamping mechanism, the turning handle drives the connecting shaft to rotate, the connecting shaft drives the driving gear to rotate, the driving gear drives the sleeve gear to rotate, thereby driving the bidirectional lead screw to rotate, the bidirectional lead screw drives the lead screw pair 1 and the lead screw pair 2 to move to both sides, driving the connecting rod to rotate, the connecting rod drives the bottom block and the movable connecting plate to move downward, and the movable The moving connecting plate drives the connecting plate and the pressing top plate to move downward, and the pressing top plate drives the connecting plate and the pressing block to move downward. The pressing block presses and fixes the optical fiber placed on the placement slot, and can clamp and fix optical fibers of different diameters, and adjust the cores of optical fibers of different diameters for welding. However, when the clamping structure inside the optical fiber welding machine is used to clamp and limit the optical fiber, the staff needs to manually shake the handle to make the clamping structure limit the optical fiber to be connected. When using the optical fiber welding machine for wiring, the general staff will not take the machine out of the suitcase for safety or convenience. Generally, they directly open the lid of the suitcase and then start the machine directly inside the suitcase and insert the optical fiber into the corresponding hole for welding. At this time, it is quite inconvenient to shake the handle to limit the optical fiber. For this reason, we propose an adjustable core optical fiber welding machine. Utility Model Content

[0003] In view of the problems in the prior art, the utility model provides an optical fiber fusion splicer with an adjustable core.

[0004] The utility model solves the technical problem by adopting a technical solution that is an adjustable core optical fiber fusion splicer, comprising a body, both sides of the outer periphery of the body are provided with jacks, a reducer is mounted inside the body, a screw for transmission is rotatably mounted at the power output end of the reducer, and a servo motor is mounted at the power input end of the reducer, a slide plate and a connecting rod for adjustment are slidably mounted inside the body, a threaded sleeve threadedly connected to the screw is mounted inside the slide plate, and a pressure plate connected to the connecting rod is slidably mounted on the top surface of the inner side of the jack;

[0005] A side of the pressure plate close to the jack is equipped with a shock-absorbing cylinder that can be used for buffering, and there are multiple groups of shock-absorbing cylinders. An end of the shock-absorbing cylinder away from the pressure plate is equipped with a rubber plate for limiting the optical fiber.

[0006] By adopting the above technical solution, when using the optical fiber fusion splicer to fuse the optical fibers, the optical fibers to be connected can be conveniently plugged into the two groups of jacks on the outside of the body, and the two groups of jacks can be conveniently connected to the fusion structure inside the body. Then, the controller provided by the body can be used to operate the servo motor inside the body. The operation of the servo motor can conveniently drive the screw to rotate under the operation of the reducer, so that the screw can be screwed with the threaded sleeve on the outer periphery of the slide plate, and the slide plate can move with the displacement of the threaded sleeve. Then, the slide plate can conveniently drive the pressure plate to move through the connecting rod, so that the pressure plate can limit the optical fiber plugged in the inner side of the jack, and the electric control method is more convenient, which is convenient for fusing the optical fiber.

[0007] When the pressure plate approaches the optical fiber inside the jack, it will first push the rubber plate close to the optical fiber. At the same time, the shock-absorbing tube between the rubber plate and the pressure plate will provide a certain buffering force, thereby reducing the impact of the pressure plate, so that the pressure plate and the rubber plate can more safely limit and clamp the optical fiber.

[0008] Specifically, both side surfaces of the outer periphery of the slide plate are equipped with sliding sleeves for connection, and there are multiple sets of sliding sleeves. The inner side of the body is equipped with vertical rods slidably connected to the sliding sleeves, and there are multiple sets of vertical rods.

[0009] By adopting the above technical solution, the vertical rod and the sliding sleeve are slidably connected to each other, so that the slide plate can slide and move inside the body more stably.

[0010] Specifically, a sponge pad for protection is bonded to the bottom surface of the rubber plate.

[0011] By adopting the above technical solution, the sponge pad has good elasticity, which is convenient for reducing scratches caused by friction between the rubber plate and the optical fiber.

[0012] Specifically, a rubber sleeve is installed between the rubber plate and the pressure plate.

[0013] By adopting the above technical solution, the rubber sleeve is easy to extend and retract, so as to seal and protect the gap between the rubber plate and the pressure plate.

[0014] Specifically, springs located at the outer periphery of the shock-absorbing cylinder are installed between the rubber plate and the pressure plate, and there are multiple groups of springs.

[0015] By adopting the above technical solution, the spring and the shock-absorbing cylinder can cooperate with each other conveniently, thereby improving the buffering effect of the pressure plate.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application is designed with a servo motor, a reducer, a slide plate, a screw, a threaded sleeve, a connecting rod, a jack and a pressure plate. When a fiber optic fusion splicer is used to fuse optical fibers, the optical fibers to be connected can be conveniently plugged into the two sets of jacks on the outside of the machine body, and the two sets of jacks can be conveniently connected to the fusion structure inside the machine body. Then, the servo motor inside the machine body can be operated by using the controller provided by the machine body. The operation of the servo motor can conveniently drive the screw to rotate under the operation of the reducer, so that the screw can be screwed with the threaded sleeve on the outer periphery of the slide plate, and the slide plate can move with the displacement of the threaded sleeve. Then, the slide plate can conveniently drive the pressure plate to move through the connecting rod, so that the pressure plate can limit the optical fiber plugged into the inner side of the jack, and the electric control method is more convenient, which is convenient for fusing optical fibers.

[0018] 2. The technical solution of the present application adopts the design of the shock-absorbing cylinder and the rubber plate. When the pressure plate approaches the optical fiber inside the jack, the rubber plate will be pushed close to the optical fiber first. At the same time, the shock-absorbing cylinder between the rubber plate and the pressure plate will provide a certain buffering force, thereby reducing the impact force of the pressure plate, so that the pressure plate and the rubber plate can more safely limit and clamp the optical fiber.

[0026] When in use, when using the optical fiber fusion splicer to fuse the optical fibers, the optical fibers to be connected can be conveniently plugged into the two groups of jacks 2 on the outside of the body 1, and the two groups of jacks 2 are conveniently connected to the fusion structure inside the body 1. Then, the controller provided by the body 1 can be used to operate the servo motor 4 inside the body 1. The operation of the servo motor 4 is convenient to drive the screw 5 to rotate under the operation of the reducer 3, so that the screw 5 can be screwed with the threaded sleeve 7 on the outer periphery of the slide plate 6, and the slide plate 6 moves with the displacement of the threaded sleeve 7. Then, the slide plate 6 is convenient to drive the pressure plate 9 to move through the connecting rod 8, so that the pressure plate 9 can limit the optical fiber plugged in the inner side of the jack 2, and the electric control method is more convenient, which is convenient for fusing the optical fiber;

[0027] When the pressure plate 9 approaches the optical fiber inside the jack 2, it will first push the rubber plate 10 close to the optical fiber. At the same time, the shock-absorbing tube 11 between the rubber plate 10 and the pressure plate 9 will provide a certain buffering force, thereby reducing the impact of the pressure plate 9, so that the pressure plate 9 and the rubber plate 10 can more safely limit and clamp the optical fiber.

[0028] like Figure 2 As shown, both side surfaces of the outer periphery of the slide plate 6 are equipped with sliding sleeves 16 for connection, and there are multiple sets of sliding sleeves 16.

[0029] When in use, the vertical rod 15 and the sliding sleeve 16 are slidably connected to each other, so that the slide plate 6 can slide and displace inside the body 1 more stably.

[0030] like Figure 2 As shown, a sponge pad 13 for protection is bonded to the bottom surface of the rubber plate 10 .

[0031] When in use, the sponge pad 13 has good elasticity, which is convenient for reducing scratches caused by friction between the rubber plate 10 and the optical fiber.

[0032] like Figure 2As shown, a rubber sleeve 14 is installed between the rubber plate 10 and the pressure plate 9.

[0033] When in use, the rubber sleeve 14 is easily retracted to seal and protect the gap between the rubber plate 10 and the pressing plate 9.

[0034] like Figure 2 and Figure 3 As shown, springs 12 are installed between the rubber plate 10 and the pressure plate 9 and are located on the outer periphery of the shock absorbing cylinder 11, and there are multiple groups of springs 12.

[0035] When in use, the spring 12 cooperates with the shock-absorbing cylinder 11 to improve the buffering effect of the pressure plate 9 .

They are screwed together, and the slide plate 6 moves with the displacement of the threaded sleeve 7. Then the slide plate 6 drives the pressure plate 9 to move through the connecting rod 8, so that the pressure plate 9 can limit the optical fiber plugged into the inner side of the jack 2, and the electric control method is more convenient, which is convenient for welding the optical fiber. When the pressure plate 9 is close to the optical fiber inside the jack 2, it will first push the rubber plate 10 close to the optical fiber. At the same time, the shock-absorbing tube 11 between the rubber plate 10 and the pressure plate 9 is convenient for a certain buffering force, thereby reducing the impact of the pressure plate 9, so that the pressure plate 9 and the rubber plate 10 can limit and clamp the optical fiber more safely.
