Description

Technical Field

[0001] This utility model relates to the field of acousto-optic modulator technology, specifically to a fiber-coupled acousto-optic modulator that is easy to assemble. Background Technology

[0002] Acousto-optic modulation is an external modulation technique. The device that controls the intensity change of a laser beam is usually called a modulator. The modulation signal is applied to the transducer in the form of an electrical signal (amplitude modulation), and then converted into a wave field that changes in the form of an electrical signal. When the light wave passes through the medium, the optical carrier is modulated and becomes an intensity-modulated wave that "carries" information. When it is necessary to couple optical fibers, an optical fiber coupled acousto-optic modulator is required. When using an optical fiber coupled acousto-optic modulator, the optical fiber and the optical fiber coupled acousto-optic modulator need to be assembled together.

[0003] However, the existing assembly method involves aligning the optical fiber with the connector on the modulator and then fixing it with a threaded ring, leaving the optical fiber exposed outside the modulator. When a long optical fiber is pulled, it can easily cause the acousto-optic modulator to shake, or it can be accidentally pulled, causing the optical fiber to fall off from the optical fiber interface. If the optical fiber is folded together for storage, it can easily cause excessive bending, thus affecting the performance of the optical fiber. Therefore, a fiber-coupled acousto-optic modulator that is easy to assemble is proposed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a fiber-coupled acousto-optic modulator that is easy to assemble and has advantages such as easy fiber storage, thus solving the problem that existing fiber-coupled acousto-optic modulators cannot store optical fibers.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fiber-coupled acousto-optic modulator that is easy to assemble, comprising a main body, wherein the main body is provided with sockets on both the left and right sides, wherein optical fibers are connected to the sockets, and a storage mechanism is provided between the optical fibers and the main body.

[0008] The storage mechanism includes connecting rods, with connecting rods fixedly installed on both the left and right sides of the main body. A storage frame is fixedly installed at the end of the connecting rod away from the main body. A storage roller is provided inside the storage frame. Mounting grooves are provided on both the front and rear side walls of the storage roller. A first spring is installed inside the mounting groove. A connecting plate is connected to the side end of the first spring. A limit rod is installed at the end of the connecting plate away from the first spring. Mounting seats are installed on both the front and rear sides of the storage frame. A push seat is slidably connected inside the mounting seat. A second spring is installed inside the push seat. A fixing plate is fixedly installed inside the mounting seat. A push rod is slidably connected to the fixing plate.

[0009] Furthermore, the upper and lower side walls of the storage frame are both open, and the front and rear sides of the storage frame are both provided with limit openings.

[0010] Furthermore, the position of the limiting opening corresponds to the position of the mounting groove, and the limiting opening is connected to the interior of the mounting base.

[0011] Furthermore, the second spring is sleeved on the outside of the push rod, which is installed through the middle of the fixed plate.

[0012] Furthermore, the end of the second spring near the fixed plate is fixedly connected to the fixed plate, and the end of the push rod away from the fixed plate is fixedly connected to the push seat.

[0013] Furthermore, the optical fiber is wound around the outside of the storage frame, and the size of the limiting rod is adapted to the size of the limiting opening.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] This easily assembled fiber-coupled acousto-optic modulator features a storage mechanism that winds the optical fiber onto a storage roller. One end of the fiber connects to the connector, while the other end can be connected to other devices. After winding, the fiber is not excessively long and exposed. The winding roller can be assembled and stored within a storage frame for further protection of the fiber. Once inside the frame, the limiting rods on both sides engage with the limiting openings, preventing rotation. This effectively stores the fiber, preventing it from being pulled. This design not only provides storage but also prevents the fiber from being pulled arbitrarily and detaching from the connector. It solves the problems of existing assembly methods where the fiber is exposed, longer fibers can cause the modulator to shake, and accidental pulling can lead to detachment from the connector. Folding the fiber for storage can also cause excessive bending, affecting fiber performance. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 The fiber-coupled acousto-optic modulator of this embodiment is easy to assemble and includes a main body 1. Both sides of the main body 1 are provided with sockets 2. Fiber optic cables 3 are connected to the sockets 2. A storage mechanism 4 is provided between the fiber optic cables 3 and the main body 1.

[0024] Specifically, the storage mechanism 4 includes connecting rods 401. Connecting rods 401 are fixedly installed on both the left and right sides of the main body 1. A storage frame 402 is fixedly installed at the end of the connecting rod 401 away from the main body 1. A storage roller 403 is provided inside the storage frame 402. Mounting grooves 404 are provided on both the front and rear side walls of the storage roller 403. A first spring 405 is installed inside the mounting groove 404. A connecting plate 406 is connected to the side end of the first spring 405. A limit rod 407 is installed at the end of the connecting plate 406 away from the first spring 405. Mounting seats 408 are installed on both the front and rear sides of the frame 402. A pusher seat 409 is slidably connected inside the mounting seat 408. A second spring 410 is installed inside the pusher seat 409. A fixing plate 411 is fixedly installed inside the mounting seat 408. A push rod 412 is slidably connected to the fixing plate 411. By setting up the storage mechanism 4, the optical fiber 3 can be wound onto the storage roller 403. One end of the optical fiber 3 is connected to the insertion port 2, and the other end can be connected to other devices. After winding, the optical fiber 3 will not be excessively long and exposed to the outside; simultaneously, after winding... After completion, the collecting roller 403 can be assembled and stored inside the collecting frame 402 to further protect the optical fiber 3. During the storage process, first connect one end of the optical fiber 3 to the socket 2, then gradually wrap the optical fiber 3 around the outside of the collecting roller 403, leaving a sufficiently long section of the optical fiber 3 for connection with other equipment. At the same time, press the limiting rods 407 on both sides to retract it into the mounting groove 404. Place the collecting roller 403 from the top of the collecting frame 402 into the interior of the collecting frame 402. At this time, the limiting rods 407 on both sides are protected by the collecting frame 402. The inner wall of 02 cannot move to the outside. When the limiting rod 407 moves to the limiting opening, it loses the squeezing limit of the storage frame 402. Under the push of the first spring 405, it will move from the mounting groove 404 to the limiting opening. At this time, the assembly of the storage roller 403 is completed. At this time, the storage roller 403 can no longer rotate. The optical fiber 3 has achieved the storage work. Due to the shortened length, the probability of it being pulled is also reduced. It not only achieves the storage function, but also prevents the optical fiber 3 from being pulled at will and causing the interface to fall off.

[0025] Furthermore, when removing the storage roller 403, simply press the pushers 409 on both sides simultaneously. The pushers 409 will then push the push rod 412 toward the limiting rod 407, and push and squeeze the limiting rod 407, gradually pushing the limiting rod 407 into the storage groove 404. At this point, the storage roller 403 loses its limit, and can then be pushed outward.

[0026] Specifically, the optical fiber 3 is wound around the outside of the storage frame 402, and the size of the limiting rod 407 is adapted to the size of the limiting opening. When the limiting rod 407 is inserted into the limiting opening, the limiting rod 407 cannot rotate.

[0027] When implementing this procedure, please follow these steps:

[0028] 1) First connect one end of the optical fiber 3 to the socket 2, then gradually wrap the optical fiber 3 around the outside of the receiving roller 403, leaving enough length of optical fiber 3 for connection with other devices.

[0029] 2) Then simultaneously squeeze the limiting rods 407 on both sides to retract them into the mounting groove 404, and then place the storage roller 403 from the top of the storage frame 402 into the interior of the storage frame 402.

[0030] 3) Finally, when the limiting rod 407 moves to the limiting opening, it loses the squeezing limit of the storage frame 402 and moves from the mounting groove 404 into the limiting opening. At this time, the storage roller 403 can no longer rotate, thus achieving storage. When taking it out, you only need to press the push seats 409 on both sides at the same time and push the storage roller 403 out of the storage frame 402.

[0031] In summary, this easily assembled fiber-coupled acousto-optic modulator, through the inclusion of a storage mechanism 4, allows the fiber optic cable 3 to be wound onto a storage roller 403. One end of the fiber optic cable 3 connects to the connector 2, while the other end can be connected to other devices. After winding, the fiber optic cable 3 is not excessively exposed. Simultaneously, the wound storage roller 403 can be assembled and stored within a storage frame 402, providing further protection for the fiber optic cable 3. Once the storage roller 403 is placed inside the storage frame 402, the limiting rods 407 on both sides will engage in the limiting openings. This prevents the storage roller 403 from rotating, thus enabling the optical fiber 3 to be stored and not easily pulled. It not only achieves the storage function but also prevents the optical fiber 3 from being pulled arbitrarily and causing it to fall off at the interface. This solves the problems in existing assembly methods where the optical fiber is exposed outside the modulator, and when a long optical fiber is pulled, it can easily cause the acousto-optic modulator to shake or be accidentally pulled, causing the optical fiber to fall off from the optical fiber interface. If the optical fiber is folded together for storage, it can easily cause excessive bending, thus affecting the performance of the optical fiber.
