Description

Technical Field

[0001] The utility model relates to the technical field of communications, and in particular to a multi-light source optical fiber transmission device. Background Art

[0002] A fiber optic transmission device is a device that transmits signals through optical fibers and is primarily composed of an optical transmitter, optical fiber, and an optical receiver. It can be categorized as analog and digital fiber optic transmission devices (based on the type of transmitted signal), as well as telecommunications-grade and non-telecommunications-grade fiber optic transmission devices (based on the application scenario). A single optical source has limitations in terms of transmission capacity, fault response, and meeting complex transmission requirements. Multiple optical sources can significantly increase the capacity of optical fiber transmission, enabling efficient simultaneous transmission of multiple signals. Furthermore, if a single optical source fails, other optical sources can ensure uninterrupted transmission, improving the overall reliability and stability of the system. Furthermore, it can better adapt to the diverse transmission requirements of different frequency bands and different types of signals, allowing optical fiber transmission to leverage its advantages in more application scenarios.

[0003] A multi-source fiber-optic transmission device typically consists of multiple light sources (such as lasers), a modulator, a coupler, optical fibers, an optical amplifier, and a photodetector. The operating principle is that multiple light sources emit different optical signals. These signals are first modulated by the modulator, where they are converted from electrical signals to optical signals. A coupler then converges these multiple optical signals and injects them into the optical fiber for transmission. During transmission, the optical amplifier amplifies the optical signals to compensate for losses. Finally, the photodetector converts the received optical signals into electrical signals, completing the transmission.

[0004] In the prior art, due to the sophisticated and complex structure of the internal components of the optical fiber transmission device and the close arrangement of the components, disassembling and inspecting components in a limited space can easily cause damage to other components, making it difficult for some transmission devices to conveniently inspect and repair their internal working components while ensuring sealing, thereby reducing maintenance efficiency, resulting in extended maintenance time and increased communication interruption time, affecting usage, and increasing the risk of component damage and maintenance costs. Therefore, a multi-light source optical fiber transmission device is proposed to solve the above problems. Utility Model Content

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figure 2 、 Figure 3 、 Figure 5 The present invention provides an embodiment of a multi-light source optical fiber transmission device, comprising a box 1, which is used to accommodate and protect internal components and provide support points for the installation and layout of subsequent mechanisms. A signal transmitter is provided inside the box 1, which can receive signals from the optical fiber input and accurately transmit these signals to the corresponding destination according to the set rules and methods, thereby ensuring the smooth flow of information during the entire optical fiber transmission process. A control switch 101 is provided on the outside of the box 1, and the entire transmission device can be started or shut down by the control switch 101. A power interface 102 is provided on the outside of the box 1, and power is provided to the entire transmission device by plugging the power cord into the power interface 102. A plurality of peripheral interfaces 103 are provided on the outside of the box 1, and the peripheral interfaces 103 have the function of expanding the function of the device and can conveniently connect various external devices. A plurality of signal lights 104 are provided on the outside of the box 1, and the signal lights 104 serve to intuitively display the operating status of the device. There are multiple heat dissipation slots 105 on both sides of the box body 1. The heat dissipation slots 105 are used to discharge the heat generated during the operation of the transmission device, so as to avoid the internal temperature of the device being too high and affecting the performance and service life of each component, and ensure that the device can work stably in a suitable temperature environment.

[0035] The top of the box body 1 is fixedly connected to a rotating column 2, which is the rotating support point for the subsequent mechanism to rotate to open and close. The outer wall of the rotating column 2 is rotatably connected to a box cover 3, which plays a role in protecting the internal components of the box body 1. When it is in a closed state, it can prevent dust, debris, etc. from entering the box body 1 and causing damage to the precision signal transmitter and other components. The internal structure of the device can be inspected by opening the box cover 3. The top of the box cover 3 is fixedly connected to a handle 6, which makes it convenient for the user to move the device and open and close the box cover 3. Two mounting plates 4 are fixedly connected to both sides of the bottom of the box body 1. The entire transmission device is installed and fixed by driving screws into the mounting plates 4, thereby ensuring the stability of the device when in use. The inside of the box body 1 is slidably connected to a quick-release mechanism 5, and the outside of the box body 1 is detachably connected to a wire fixing mechanism 7.

[0036] The quick release mechanism 5 includes two latch posts 502, which are key components for realizing the connection and separation functions of the entire quick release mechanism 5. The outer walls of the two latch posts 502 are slidably connected to the interior of the box body 1, thereby limiting the movement direction of the latch posts 502. One end of the latch post 502 is fixedly connected to a top block 503, which plays the role of transmitting force. The outer wall of the top block 503 is fixedly connected to a return spring 504, and the other ends of the two return springs 504 are fixedly connected to the outer wall of the box body 1. When the external force disappears, the return spring 504 can rely on its own elasticity to restore the deformation, thereby driving the top block 503 and the latch post 502 connected thereto to perform corresponding movements, providing power support for the automatic reset of the entire quick release mechanism 5. The bottom of the box cover 3 is fixedly connected to two docking posts 501. The outer wall of the latch post 502 is detachably connected to the inner wall of the docking post 501. The docking posts 501 and the latch post 502 cooperate with each other. When the latch post 502 slides inward and inserts into the inner wall of the docking post 501, the box cover 3 is firmly fixed to the box body 1, preventing the box cover 3 from shaking or being accidentally opened, thus ensuring the sealing of the box body 1. When the latch post 502 slides outward and separates from the docking post 501, the box cover 3 can be rotated around the rotating post 2 to open. The outer wall of the box body 1 is fixedly connected to a drive assembly.

[0037] The drive assembly includes multiple fixed piles 505, the outer walls of which are fixedly connected to the outer wall of the housing 1. The fixed piles 505 serve as a fixing and supporting mechanism, providing a stable foundation for the installation of the entire drive assembly on the housing 1. Two adjacent ends of the fixed piles 505 are fixedly connected to a rotating shaft 506, the outer wall of which is rotatably connected to a cam 507. The rotating shaft 506 serves as the axis of rotation for the cam 507, providing a support point for the cam 507 to rotate around, allowing the cam 507 to perform circular motion. The outer wall of the cam 507 contacts the outer wall of the top block 503. Due to the irregular shape of the outer wall of the cam 507 itself, the contact state between the cam 507 and the top block 503 can be changed during rotation, thereby affecting the sliding of the latch column 502 through the top block 503.

[0038] Reference Figure 1 、 Figure 2 、 Figure 4 The line fixing mechanism 7 includes a protective plate 701. The outer wall of the protective plate 701 is detachably connected to the outer wall of the box 1. The protective plate 701 mainly serves to protect the internal components of the line fixing mechanism 7. The outside of the box 1 is provided with multiple fiber optic docking ports 702. The multiple fiber optic docking ports 702 are used to connect different types of light source optical fibers. The fiber optic docking ports 702 are ports for connecting the entire line fixing mechanism 7 with external optical fibers. Different types of optical fibers can be inserted into different fiber optic docking ports 702. The outside of the box 1 is fixedly connected with multiple telescopic columns 703. The telescopic columns 703 can be telescopically moved within a certain range, thereby supporting the subsequent structure. The telescopic end of the telescopic column 703 is fixedly connected to a driving spring 704, and the other end of the driving spring 704 is fixedly connected to the fixed section of the telescopic column 703. The driving spring 704 has the function of storing and releasing elastic potential energy. When the telescopic column 703 is subjected to external force and contracts or extends, the driving spring 704 will be compressed or recover its deformation accordingly, and react to the telescopic column 703 through its own elastic force, providing power support for the movement of the telescopic column 703, ensuring that the telescopic column 703 can accurately perform telescopic operations according to the corresponding motion logic.

[0039] Multiple sliding plates 705 are slidably connected to the exterior of the housing 1, allowing them to slide in a specific direction. Multiple drive springs 704 are fixedly connected to the far sides of the two sliding plates 705 at either end. Multiple transmission springs 706 are fixedly connected to the adjacent sides of the multiple sliding plates 705 in the middle. When a sliding plate 705 at one end is moved by an external force, the drive springs 704 and transmission springs 706 drive the other sliding plates 705 to slide accordingly, ensuring coordinated movement among the various components of the cable securing mechanism 7. Two deformable cable securing rings 707 are fixedly connected to adjacent sides of the two sliding plates 705. When an optical fiber is inserted into the fiber docking port 702, a series of transmission actions drive the sliding plates 705 to move, thereby closing the cable securing rings 707. The cable securing rings 707 can deform appropriately based on the thickness of the optical fiber, tightly wrapping the optical fiber and achieving adaptive clamping of the optical fiber.

[0040] Working principle: When using the transmission device, remove the protective plate 701, pull the two sliding plates 705 in the middle to compress the transmission spring 706, and then drive multiple sliding plates 705 to move synchronously through the action of the transmission spring 706, thereby causing the telescopic column 703 to contract, the driving spring 704 to compress, and drive the wire fixing ring 707 to open, and then insert different optical fibers into the corresponding optical fiber docking port 702, loosen the sliding plate 705, and the driving spring 704 recovers its deformation to drive the telescopic column 703 to extend, thereby driving the sliding plates 705 at both ends to move closer to the middle, and then through the transmission action of the transmission spring 706, all the sliding plates 705 are driven to move closer to the direction of the optical fiber, and through the action of the transmission spring 706, the force on each sliding plate 705 is balanced, thereby driving the two corresponding wire fixing rings 707 to close, thereby completing the adaptive fixed clamping of the optical fiber, and preventing the optical fiber from shaking during use and causing the docking part to loosen. Then connect a power cord to the power interface 102 and connect the required peripherals to the peripheral interface 103 , turn on the control switch 101 and the entire transmission device is put into operation through the signal transmitter.

[0041] When it is necessary to inspect the interior of the transmission device, the cam 507 is rotated to rotate along the rotating shaft 506. During the rotation process, due to the irregular shape of the outer wall of the cam 507, the end with the smaller radius rotates to the position where the top block 503 contacts the top block 503, so that the top block 503 is not under pressure, and the reset spring 504 restores the deformation to drive the top block 503 to move outward, thereby driving the latch post 502 to slide outward and separate from the docking post 501. The box cover 3 can be rotated along the rotating column 2 as the center by pulling the handle 6, thereby opening the box cover 3, making it convenient for the user to inspect the interior of the transmission device. After the inspection is completed, the box cover 3 is closed and the cam 507 is rotated in the opposite direction, thereby generating pressure on the top cover, thereby compressing the spring and driving the latch post 502 to slide inward and engage with the docking post 501, completing the closing operation of the box body 1.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
