Description

Technical Field

[0001] This invention relates to the field of optical wave modulation technology, specifically to a highly stable integrated optical waveguide modulator with anti-offset capabilities. Background Technology

[0002] An optical waveguide is a structure used to transmit optical signals in optical devices. Based on the principle of total internal reflection of light waves, it guides the light beam along a specific path to achieve control and modulation of the optical signal. An optical waveguide modulator is an optical device used to modulate optical signals. It can achieve modulation and control of optical signals by changing the refractive index or phase in the optical waveguide. One of the most common and widely used modulation mechanisms is electro-optic modulation. This mechanism is based on the electro-optic effect. Applying an electric field to a specific material will change the refractive index of the material, thereby modulating the optical signal. Optical waveguide modulators have advantages such as fast response, high modulation depth, low power consumption, and small size, and are suitable for fields such as optical communication, optical sensing, optical signal processing, and optical computing.

[0003] Optical waveguide modulators play a crucial role in optical systems for modulating, controlling, and regulating optical signals. They can perform functions such as encoding, decoding, amplitude modulation, and phase modulation of optical signals, providing important technical support for applications such as optical communication, optical sensing, optical signal processing, and optical computing. However, during the transmission and modulation of optical signals, prolonged use of optical waveguide modulators can cause the mounting and fixing components on both sides of the modulator to shift or loosen. This can easily lead to modulator misalignment, resulting in a shift in the electric field inside the modulator, which in turn can cause the modulation mechanism to malfunction or even damage the modulator.

[0004] In addition, during the use of the optical waveguide modulator, the unstable external environment may cause the optical waveguide fiber to move, which may cause the connection between the two ends of the optical waveguide modulator and the optical waveguide fiber to bend. This may cause the connection between the optical waveguide modulator and the optical waveguide fiber to break. At the same time, it may also cause additional loss in the modulation of the optical signal, or cause the modulation of the optical signal to be incorrect. Summary of the Invention

A slider is slidably connected inside each of the four sliding slots, and the side cross-section of the slider is I-shaped. A rubber fixing block is fixedly connected to the side of the slider that is close to each other. Four long connecting rods are provided between the rubber fixing blocks and the rotating sleeve.

One cylindrical protrusion is rotatably connected to the slider, and the other cylindrical protrusion is rotatably connected to the rotating sleeve.

[0013] Furthermore, the limiting bracket assembly includes arc-shaped support plates fixedly connected to the left and right sides of the modulator body, and the limiting bracket assembly is symmetrically arranged with reference to the central axis of the modulator body.

[0017] (III) Beneficial Effects

[0018] The high-stability integrated optical waveguide modulator with anti-offset provided by this invention has the following beneficial effects:

[0019] 1. A fixed-length arc-shaped support plate is connected to both sides of the modulator body. After the optical waveguide fiber is connected, a section that remains straight will be formed on both sides of the modulator body. By maintaining the straightness of the optical waveguide fiber access end, signal loss during transmission can be reduced, ensuring high signal quality and reliability. At the same time, it also avoids bending at the connection between the two sides of the optical waveguide modulator body and the optical waveguide fiber, thereby reducing the damage rate of the optical waveguide fiber under the usage environment after connection. Thus, while achieving good signal transmission, it also greatly ensures the durability of the optical waveguide fiber, making it more suitable for widespread application in the telecommunications field.

[0020] 2. Each limiting roller is attached to the outer wall of the optical waveguide fiber to provide good support and stability. This not only prevents the optical waveguide fiber from accidentally falling off after connection, but also ensures that the optical waveguide fiber and the modulator body have a continuous and stable signal output, thus ensuring the reliability of the signal output of the modulator body.

[0021] 3. The user rotates the rotating sleeve with torque, and gradually contacts the outer wall of the screw with each slider and rubber fixing block. This ensures the coaxiality of the screw with the rotating sleeve during installation, preventing the screw from shifting during tightening. In this way, not only is screw shifting prevented, but coaxiality during tightening is also ensured, thus guaranteeing the stability of the screw during installation. Moreover, after the screw is installed in place, the rubber fixing blocks adhere to the outer wall of the screw, which also provides a secondary tightening effect, preventing the modulator body from shifting or loosening after installation. This effectively avoids modulation mechanism failure in the modulator body, thus providing a good and stable effect during the use of the modulator body. Attached Figure Description

[0039] Furthermore, a highly stable integrated optical waveguide modulator with anti-displacement capability also includes optical waveguide limiting mechanisms 4 symmetrically arranged on the left and right sides of the modulator body 1.

[0040] Furthermore, the optical waveguide limiting mechanism 4 includes a limiting bracket assembly 41 disposed on the left and right sides of the modulator body 1 to prevent bending at the connection of the optical waveguide fiber 5, a limiting fixing assembly 42 disposed inside the end of the limiting bracket assembly 41 away from the modulator body 1 to squeeze and fix the optical waveguide fiber 5, and a limiting adjusting assembly 43 disposed at the end of the limiting bracket assembly 41 away from the modulator body 1 to adjust the squeezing degree of the limiting fixing assembly 42.

[0044] Preferably, the threaded rod 434 passes through the sliding block 433.

[0045] The following are all the working steps and working principles of the above embodiments:

[0046] The modulator body 1 is used to: be installed in a telecommunications or wireless communication system to convert analog signals into digital signals or digital signals into analog signals. Specifically, the modulator body 1 is installed in a telecommunications base station and can be fixed to the place of use with screws.

[0047] Initial state:

[0048] The modulator body 1 is not installed in the telecommunications base station, that is, no screws are installed in the rotating sleeve 313 with internal threads. At the same time, the left and right sides of the modulator body 1 are not connected to the optical waveguide fiber 5, and no other lines are connected at the electrical signal input port 2 on the modulator body 1.

[0049] The slider 323, whose side sections are all I-shaped, is located in the sliding groove 322 on the upper surface of the fixed plate 321. At this time, the slider 323 and the rubber fixing block 324 are both located away from the center of the circular groove in the fixed plate 321.

[0050] The specific steps and principles of using the modulator fixing mechanism 3 are as follows:

[0051] First, the user can place the modulator body 1 in the position to be installed. In order to ensure that the modulator body 1 is installed in the correct position, the user can use the positions of the four mounting plates 311 as reference points for fixing the modulator body 1 during the installation process. That is, during installation, the user can align the four mounting plates 311 to the position to be installed, thereby providing the user with a reference for the placement of the modulator body 1 before installation.

[0052] Subsequently, the user retrieves the screws used to install the modulator body 1 and inserts them into the rotating sleeve 313. After all the screws in the rotating sleeves 313 of the four mounting plates 311 have been placed, the user pinches the outer wall of the rotating sleeve 313 and applies a torque to rotate it in the forward direction. At this time, the screws will gradually engage with the threads on the inner wall of the rotating sleeve 313. Simultaneously, as the rotating sleeve 313 rotates, it will cause the long connecting rod 325 on its upper surface to deflect. Since the long connecting rod 325 is also rotatably connected to the slider 323, and the slider 323 slides inside the sliding groove 322, the slider 323 and the rubber fixing block 324 will gradually slide along the trajectory of the sliding groove 322 under the action of the deflection force of the long connecting rod 325, and gradually slide towards the center of the circular groove in the fixing plate 321. After sliding displacement towards the center of the circular groove along with the rubber fixing block 324, they gradually come into contact with the outer wall of the screw. By utilizing the torque of the user rotating the rotating sleeve 313, and in combination with the gradual contact of each slider 323 and the rubber fixing block 324 with the outer wall of the screw, the coaxiality of the screw and the rotating sleeve 313 is ensured during the installation process, preventing the screw from shifting during the tightening process. In this way, during the installation of the screw, not only can the screw shift be prevented to ensure the coaxiality of the screw during the tightening process, thus ensuring the stability of the screw during the installation process, but also after the screw is installed, the rubber fixing blocks 324 can be used to adhere to the outer wall of the screw to achieve a secondary tightening effect, preventing the position of the modulator body 1 from shifting or loosening after installation. This reasonably avoids the situation of modulation mechanism failure of the modulator body 1, and thus provides a good stability effect during the use of the modulator body 1.

[0053] Next, the user can connect the optical waveguide fiber 5 to the left and right sides of the modulator body 1. When connecting the optical waveguide fiber 5, the user needs to pass the optical waveguide fiber 5 through the center of the annular bracket 413. After the optical waveguide fiber 5 is connected and adjusted to the modulator body 1, the user then holds one end of the threaded rod 434 and applies a torque that allows it to rotate in the forward direction. As the threaded rod 434 rotates, it will cause the sliding block 433, which is threaded to it, to move along the outer wall of the threaded rod 434. Since the sliding block 433 is rotatably connected to the annular bracket 413... The arc-shaped protrusion of the bracket 413 causes the annular bracket 413 to rotate synchronously with the displacement of the sliding block 433. This rotation of the annular bracket 413 then causes the rotating cylinder 422 to move synchronously. At this time, the connecting rods 423 sliding within the rotating cylinder 422 rotate, causing the limiting roller 424 to gradually approach and adhere to the outer wall of the optical waveguide fiber 5. The user then judges whether to continue rotating the threaded rod 434 based on the tightness of the fit between the limiting roller 424 and the optical waveguide fiber 5. If the tightness is sufficient... When the rotation of the threaded rod 434 stops, the limiting rollers 424 adhere to the outer wall of the optical waveguide fiber 5, providing good support and stability. This not only prevents accidental detachment of the optical waveguide fiber 5 after connection, ensuring a continuous and stable signal output between the optical waveguide fiber 5 and the modulator body 1, thus guaranteeing the reliability of the signal output from the modulator body 1, but also, since the optical waveguide limiting mechanism 4 is connected to both sides of the modulator body 1 via a fixed-length arc-shaped support plate 411, a section that remains straight on both sides of the modulator body 1 is formed after the optical waveguide fiber 5 is connected. By maintaining the straightness of the optical waveguide fiber 5's input end, signal loss during transmission can be reduced, ensuring high signal quality and reliability. It also prevents bending at the connection points between the optical waveguide modulator body 1 and the optical waveguide fiber 5, reducing the damage rate of the optical waveguide fiber 5 under operating conditions. Therefore, while achieving good signal transmission, it also greatly ensures the durability of the optical waveguide fiber 5, making it more suitable for widespread application in the telecommunications field.
