[0002] According to Chinese Patent No. CN219936234U, this utility model relates to the field of acousto-optic modulator technology, and in particular to a fiber-optic coupled acousto-optic modulator that is easy to assemble. It includes a main body, a socket, and a clamping plate. One side of the main body is fixedly connected to one end of the socket. A first threaded post is provided on one side of the socket. One end of the first threaded post is connected to the main body via a rotating shaft. The first threaded post is threaded to one end of a threaded block, causing a limiting block to clamp the optical fiber. Simultaneously, the clamping plate clamps the connection between the connector and the optical fiber using a rubber pad. This achieves both fixing and sealing of the optical fiber, preventing it from falling off due to arbitrarily pulling. The rubber pad seal prevents water from entering the gaps at the connection. When support for the optical fiber is needed, the limiting block is pulled, and the limiting block moves via a sliding rod. The sliding rod supports the limiting block, and the limiting block supports the optical fiber, demonstrating the practicality of this device.

[0023] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:
[0026] Reference Figure 1-4A modularly coupled mini fiber-optic coupled acousto-optic modulator includes an acousto-optic controller housing 1. The bottom of the housing 1 has a base plate 10. Positioning buckles 9 are provided on three sides of the base plate 10, with two buckles 9 on each side. The positioning buckles 9 are glued to the base plate 10. Positioning holes 11 are provided on three sides of the housing 1, with two holes 11 on each side, corresponding one-to-one with the positioning buckles 9. Positioning blocks 8 have internal positioning holes 12, which are cut out. Positioning blocks 8 are provided on the front and two sides of the housing 1. One positioning block is provided at each end of the front, and one positioning block 8 is provided at the end of each side furthest from the front. The outer edges of the positioning blocks 8 are rounded. The base plate 10 has a first positioning clip 5 and a second positioning clip 6 on its two sides, respectively, and the first positioning clip 5 and the second positioning clip 6 are glued to the corresponding sides of the base plate 10. The front of the base plate 10 has a third positioning clip 7, and the top of the third positioning clip 7 is rounded. The front of the acoustic-optical controller housing 1 has a control line 4. One side of the acoustic-optical controller housing 1 has a first optical fiber 2, and the other side of the acoustic-optical controller housing 1 has a second optical fiber 3. Of the first optical fiber 2 and the second optical fiber 3, one is the input optical fiber for the signal to be modulated, and the other is the output optical fiber for the modulated signal. The control line 4 inputs the electrical signal generated by the external device (such as a signal generator) to the acoustic-optical modulator, thereby modulating the optical signal.
[0027] By using positioning holes 11 on the surface of the sound and light controller housing 1 and positioning buckles 9 on the side of the base plate 10, installation is achieved by simply pressing the sound and light controller housing 1 downwards. When the bottom of the sound and light controller housing 1 is in contact with the top of the base plate 10, the positioning holes 11 and positioning buckles 9 are connected one-to-one. This allows for initial positioning during installation, and the connection between the sound and light controller housing 1 and the base plate 10 can be achieved with a simple downward pressing operation, without the need for complicated tools or cumbersome steps, greatly improving installation efficiency. It also ensures that the sound and light controller housing 1 can accurately fit with the base plate 10 during installation, guaranteeing the relative positional accuracy between various components, which is beneficial to the normal operation and performance stability of the modulator. Positioning blocks 8 are provided on the front and sides of the sound and light controller housing 1, and positioning holes 12 are provided inside the positioning blocks 8. After initial positioning, positioning bolts can be used to connect the housing to the base plate 10 through the positioning holes 12. The device is designed for positioning and connection, for example, positioning on the inside of the device housing. Based on the initial positioning, secondary positioning is performed by cooperating with the positioning bolts and positioning holes 12. This can further improve the accuracy of the connection between the acoustic and light controller housing 1 and the device, ensuring that the relative positions between the various components are more precise. This is beneficial to improving the performance and stability of the modulator. The positioning bolt connection method can provide strong fastening force, making the connection between the acoustic and light controller housing 1 and the device more secure. It can withstand a certain amount of external force and vibration, reducing the possibility of equipment failure due to loose connection. The base plate 10 is provided with a first positioning clamp 5, a second positioning clamp 6, and a third positioning clamp 7 on three sides respectively. The first positioning clamp 5, the second positioning clamp 6, and the third positioning clamp 7 fix the first optical fiber 2, the second optical fiber 3, and the control line 4 respectively, which can prevent the lines from shifting or falling off due to vibration, pulling, etc. during the operation of the equipment, effectively protecting the stability of the line connection and reducing the problem of poor contact caused by loose lines. Small fiber-coupled acousto-optic modulators may experience line tension during vibration or impact. Fixing the lines and maintaining appropriate slack can significantly reduce vibration transmission and prevent fatigue failure. The first positioning clip 5, the second positioning clip 6, and the third positioning clip 7 correspond to the three lines: the first optical fiber 2, the second optical fiber 3, and the control line 4, respectively. This allows for easy identification at a glance. An unfixed first optical fiber 2 may shift and touch the casing or other components, leading to electromagnetic interference or abnormal grounding circuits. This also reduces the risk of line contact strays and signal quality degradation. Specific Implementation Example 2:
[0029] Reference Figure 1-4 The system employs sliding grooves on both sides of the sound and light controller housing 1. The positioning clips 9 of the base plate 10 are aligned with and inserted into the grooves. Then, the sound and light controller housing 1 is gently slid to engage the positioning clips 9 into specific slots for secure installation. This structure ensures quick installation while also providing some protection against accidental activation and shock absorption.
[0030] In summary:
[0031] The acoustic and light controller housing 1 has positioning holes 11 on its surface and positioning buckles 9 on one side of the base plate 10. This allows for easy installation by simply pressing the acoustic and light controller housing 1 downwards. When the bottom of the acoustic and light controller housing 1 is in contact with the top of the base plate 10, the positioning holes 11 and positioning buckles 9 are connected one-to-one. This allows for initial positioning during installation, and the connection between the acoustic and light controller housing 1 and the base plate 10 can be achieved with a simple downward pressing operation. No complicated tools or cumbersome steps are required, which greatly improves installation efficiency and ensures that the acoustic and light controller housing 1 can accurately fit with the base plate 10 during installation. This ensures the relative positional accuracy between the components and is beneficial to the normal operation and performance stability of the modulator.
[0032] The acoustic and visual controller housing 1 is equipped with positioning blocks 8 on the front and sides, and positioning holes 12 inside the positioning blocks 8. After initial positioning, positioning bolts can be used to connect the housing to the equipment through the positioning holes 12. Based on the initial positioning, secondary positioning is performed by the cooperation of the positioning bolts and the positioning holes 12, which can further improve the accuracy of the connection between the acoustic and visual controller housing 1 and the equipment. This ensures that the relative positions between the components are more accurate, which is beneficial to improving the performance and stability of the modulator. The connection method of the positioning bolts can provide strong fastening force, making the connection between the acoustic and visual controller housing 1 and the equipment more secure, able to withstand a certain amount of external force and vibration, and reducing the possibility of equipment failure due to loose connection.
[0033] The base plate 10 is equipped with a first positioning clamp 5, a second positioning clamp 6, and a third positioning clamp 7 on three sides respectively. The first positioning clamp 5, the second positioning clamp 6, and the third positioning clamp 7 fix the first optical fiber 2, the second optical fiber 3, and the control line 4 respectively. This can prevent the lines from shifting or falling off due to vibration, pulling, or other reasons during equipment operation, effectively protect the stability of the line connection, and reduce the problem of poor contact caused by loose lines.
