Description

Technical Field

[0001] This utility model belongs to the field of optical isolator fixing technology, specifically relating to a fixture for assisting in fixing the core of an optical isolator. Background Technology

[0002] An optical isolator is a passive optical device that allows only unidirectional light to pass through. Its working principle is based on the non-reciprocity of Faraday rotation. Light reflected back from the optical fiber can be effectively isolated by the optical isolator. Optical isolators primarily utilize the Faraday effect of magneto-optical crystals. The characteristics of an optical isolator are: low forward insertion loss, high reverse isolation, and high return loss. An optical isolator is a passive device that allows light to pass in one direction while blocking light from passing in the opposite direction. Its function is to restrict the direction of light, ensuring that light can only propagate in one direction. Light reflected back from the optical fiber can be effectively isolated by the optical isolator, improving optical wave transmission efficiency.

[0003] The prior art includes a fixture for fixing an auxiliary optical isolator core, patent publication number CN117706719B. In use, an Allen wrench inserted into the Allen hole rotates the set screw. During rotation, the set screw rises or falls along the axial direction of the screw hole due to the action of the screw hole, thereby causing the boss to rise or fall along the second countersunk hole. This adjusts the height of the boss protruding from the second countersunk hole and out of the base. However, in practical use, this fixture has the following shortcomings: In practice, when encountering isolators of special sizes, it is necessary to replace the boss with one of different diameters to facilitate fixing the external magnetic ring and thus the isolator core. However, replacing the boss is cumbersome and time-consuming, making it difficult to quickly fix magnetic rings of different diameters, resulting in low work efficiency.

[0004] Therefore, a fixture is needed to assist in fixing the optical isolator core, which can solve the problems in the existing technology where the process of replacing the boss is cumbersome and time-consuming when encountering isolators of special sizes and specifications, and the inability to quickly fix magnetic rings of different diameters, resulting in low work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a fixture for fixing an auxiliary optical isolator core, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fixture for fixing an auxiliary optical isolator core, comprising a base, a boss, a limiting groove, and a fixing mechanism. The boss is disposed inside the base, and the limiting grooves are symmetrically formed inside the boss. The fixing mechanism is disposed inside the boss.

[0007] The fixing mechanism consists of a motor, a fixing rod, a lead screw, a connecting assembly, a connecting plate, an arc-shaped telescopic plate, and an anti-slip layer. The boss has an installation groove inside, and the motor is fixedly connected inside the installation groove. A vertical circular groove is provided below the installation groove, and the fixing rod is fixedly connected inside the upper part of the vertical circular groove. The lead screw is rotatably connected above the fixing rod, and the output end of the motor is connected to the top end of the lead screw.

[0008] It should be noted in the solution that there are three limiting grooves, which are set in a fan shape and have symmetrical vertical circular grooves on the outside.

[0009] It is further worth noting that the connecting assembly consists of a connecting ring, a connecting seat, and a connecting rod. The two ends of the connecting rod are symmetrically and rotatably connected to the connecting seat. The connecting seat on one side is fixedly connected to the outside of the connecting ring, and the connecting plate is fixedly connected to the outside of the connecting seat on the other side.

[0010] Furthermore, it should be noted that the end of the connecting rod near the connecting ring is slidably connected to the inside of one side of the limiting groove. The limiting groove can restrict the movement trajectory of the connecting component, ensuring that the connecting component can move stably in a straight line along a predetermined path, thereby achieving precise fixation of the magnetic ring.

[0011] In a preferred embodiment, the arc-shaped telescopic plate is fixedly connected to one side of the connecting plate, and the anti-slip layer is disposed on the outer side of the arc-shaped telescopic plate. Through the arc-shaped design of the arc-shaped telescopic plate, it can better adapt to the shape of the magnetic ring and achieve a tight fit and fixation.

[0012] In a preferred embodiment, the anti-slip layer is made of rubber. The rubber anti-slip layer can increase the friction between the arc-shaped telescopic plate and the magnetic ring, preventing the magnetic ring from sliding or loosening during the fixing of the optical isolator core, and improving the stability of the fixture.

[0013] In a preferred embodiment, the number of connecting components is three sets, with the lower two sets of connecting rings fixedly connected to the outside of the fixed rod, and the upper connecting ring threadedly connected to the outside of the lead screw.

[0014] Compared with the prior art, the fixture for fixing the auxiliary optical isolator core provided by this utility model has at least the following beneficial effects:

[0015] With its fixed mechanism, this fixture can fix magnetic rings of different diameters without replacing the boss when encountering isolators of special sizes and specifications, thus greatly shortening the fixing and installation time of the optical isolator core and improving work efficiency. Moreover, it can quickly fix magnetic rings of different diameters, thereby adapting to optical isolator cores of different specifications and shapes, and improving the versatility and flexibility of the fixture.

[0021] The present invention will be further described below with reference to the embodiments.

[0022] Please see Figure 1-4 This utility model provides a fixture for fixing an auxiliary optical isolator core, including a base 1, a boss 2, a limiting groove 3 and a fixing mechanism 4. The boss 2 is disposed inside the base 1, and the limiting groove 3 is symmetrically opened inside the boss 2. The fixing mechanism 4 is disposed inside the boss 2.

[0023] The fixing mechanism 4 consists of a motor 401, a fixing rod 402, a lead screw 403, a connecting assembly 404, a connecting plate 405, an arc-shaped telescopic plate 406, and an anti-slip layer 407. The boss 2 has an installation groove inside, and the motor 401 is fixedly connected to the inside of the installation groove. A vertical circular groove is provided below the installation groove, and the fixing rod 402 is fixedly connected to the upper part of the inside of the vertical circular groove. The lead screw 403 is rotatably connected to the upper part of the fixing rod 402, and the output end of the motor 401 is connected to the top end of the lead screw 403.

[0024] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that there are three limiting grooves 3, which are set in a fan shape and have vertical circular grooves symmetrically opened on the outside.

[0025] Further as Figure 2 , Figure 3 and Figure 4As shown, it is worth noting that the connecting assembly 404 consists of a connecting ring 4041, a connecting seat 4042, and a connecting rod 4043. The two ends of the connecting rod 4043 are symmetrically rotatably connected to the connecting seat 4042. One side of the connecting seat 4042 is fixedly connected to the outside of the connecting ring 4041, and the connecting plate 405 is fixedly connected to the outside of the connecting seat 4042 on the other side.

[0026] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the end of the connecting rod 4043 near the connecting ring 4041 is slidably connected to the inside of one side of the limiting groove 3;

[0027] The movement trajectory of the connecting component 404 can be restricted by the limiting groove 3, ensuring that the connecting component 404 can move stably in a straight line along a predetermined path, thereby achieving precise fixation of the magnetic ring.

[0028] As can be seen from the above working process, by setting the fixing mechanism 4, when encountering isolators of special size and specifications, the fixture can fix magnetic rings of different diameters without replacing the boss 2, thereby greatly shortening the fixing and installation time of the optical isolator core and improving work efficiency; it can quickly fix magnetic rings of different diameters, thus adapting to optical isolator cores of different specifications and shapes, and improving the versatility and flexibility of the fixture.

[0029] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the arc-shaped telescopic plate 406 is fixedly connected to one side of the connecting plate 405, and the anti-slip layer 407 is provided on the outside of the arc-shaped telescopic plate 406.

[0030] The arc-shaped design of the arc-shaped telescopic plate 406 allows it to better adapt to the shape of the magnetic ring, achieving a tight fit and fixation.

[0031] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the anti-slip layer 407 is made of rubber.

[0032] The anti-slip layer 407 made of rubber material can increase the friction between the arc-shaped telescopic plate 406 and the magnetic ring, preventing the magnetic ring from sliding or loosening during the process of fixing the optical isolator core, and improving the stability of the fixture.

[0033] Further as Figure 2 , Figure 3 and Figure 4As shown, it is worth noting that there are three sets of connecting components 404. The two lower sets of connecting rings 4041 are fixedly connected to the outside of the fixed rod 402, and the upper connecting ring 4041 is threadedly connected to the outside of the lead screw 403.

[0034] This solution has the following working process: In use, firstly, the threaded rod below drives the boss 2 to extend above the base 1. Then, the magnetic ring is placed outside the boss 2. The external controller starts the motor 401, which drives the lead screw 403 to rotate. The connecting ring 4041 above moves down, driving the three connecting rods 4043 to rotate, thereby moving the arc-shaped telescopic plate 406 away from the boss 2. At the same time, it drives the two sets of connecting components 404 below to rotate, ensuring the stability of the movement of the arc-shaped telescopic plate 406 until the anti-slip layer 407 is close to the inner wall of the magnetic ring, fixing the magnetic ring and facilitating the fixation of the optical isolator core. By controlling the motor 401 to rotate in the opposite direction, the controller can drive the arc-shaped telescopic plate 406 away from the inner wall of the magnetic ring, releasing the fixation of the magnetic ring and facilitating the disassembly of the magnetic ring, thus improving the practicality of the fixture.

[0035] In summary: With the fixed mechanism 4, the fixture can fix magnetic rings of different diameters without replacing the boss 2 when encountering isolators of special sizes and specifications, thus greatly shortening the fixing and installation time of the optical isolator core and improving work efficiency; it can quickly fix magnetic rings of different diameters, thereby adapting to optical isolator cores of different specifications and shapes, and improving the versatility and flexibility of the fixture.
