Description
Technical Field
[0001] This utility model relates to the field of optical module transmission terminal technology, and in particular to a low-power high-speed optical module transmission terminal. Background Technology
[0002] With the rapid development of 5G communication, cloud computing, and big data technologies, optical modules, as core components for high-speed data transmission, directly impact the efficiency of the entire communication system through their performance and reliability. Traditional optical module transmission terminals, while pursuing high speed and low power consumption, face the dual challenges of interface protection and stability. Especially in complex environments, factors such as dust and moisture can easily lead to interface contamination, resulting in signal attenuation or transmission interruption. To meet the demands of modern communication equipment for high stability and long lifespan, a new type of low-power, high-speed optical module transmission terminal is needed. By optimizing the mechanical structure and protective design, this terminal can solve the problem of interface contamination while ensuring transmission efficiency, thus adapting to demanding application scenarios.
[0003] Currently, the interface protection of optical module transmission terminals mostly adopts passive dustproof structures, such as fixed rubber plugs or manually openable dust covers. These structures usually rely on manual operation by the user to achieve interface sealing through physical shielding.
[0004] The existing dustproof design of optical module transmission terminals has significant defects. The dustproof structure lacks an automatic reset function, which makes the interface prone to dust accumulation after frequent use due to failure to seal in time. Long-term exposure of the interface can cause metal contact oxidation or foreign object blockage due to dust intrusion, which can lead to poor contact, reduced signal transmission performance, or even hardware damage. This problem is particularly prominent in industrial environments or high dust scenarios, which not only increases maintenance costs but also shortens the service life of the equipment. Therefore, a low-power high-speed optical module transmission terminal is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a low-power high-speed optical module transmission terminal, which aims to improve the problem of poor interface contact and decreased transmission performance caused by dust accumulation in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A low-power high-speed optical module transmission terminal includes a module body, a protective frame one fixedly connected to the top of the module body, a protective frame two provided on the top of the protective frame one, a heat dissipation window provided inside the protective frame two, a fixed frame fixedly connected to the outer wall of the protective frame one, a fixed column fixedly connected inside the fixed frame, a circular frame fixedly connected to the outer wall of the fixed column, and a dustproof component provided at the bottom of the circular frame.
[0008] The dustproof component includes a dustproof cover, the top of which is fixedly connected to the bottom of the circular frame. A torsion spring is sleeved on the outer wall of the circular frame. One end of the torsion spring is fixedly connected to the outer wall of the fixed frame, and the other end of the torsion spring is fixedly connected to the top of the dustproof cover. A hollow cylinder is fixedly connected inside the second protective frame, and a buckle assembly is provided inside the hollow cylinder.
[0009] As a further description of the above technical solution:
[0010] The buckle assembly includes a locking ball, which is slidably connected inside the hollow cylinder, and the outer wall of the locking ball engages with the protective frame.
[0011] As a further description of the above technical solution:
[0012] A trapezoidal column is slidably connected inside the hollow cylinder, and the trapezoidal column is in contact with the ball.
[0013] As a further description of the above technical solution:
[0014] A fixed plate is fixedly connected inside the hollow cylinder, and a pressing column is slidably connected inside the fixed plate.
[0015] As a further description of the above technical solution:
[0016] The bottom of the pressing column is fixedly connected to the top of the trapezoidal column, and a pressing handle is fixedly connected to the top of the pressing column.
[0017] As a further description of the above technical solution:
[0018] A sliding disc is fixedly connected to the outer wall of the pressing column, and the sliding disc is slidably connected to the inner wall of the hollow cylinder.
[0019] As a further description of the above technical solution:
[0020] A compression spring is fitted on the outer wall of the pressing column. One end of the compression spring is fixedly connected to the bottom of the sliding plate, and the other end of the compression spring is fixedly connected to the top of the fixed plate.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, the torsion spring, in coordination with the circular frame, dust cover, and fixed frame, drives the dust cover to open and close. When the optical module transmission terminal interface is in use, external force drives the dust cover to rotate around the fixed post, compressing the torsion spring and opening the dust cover. After use, the torsion spring releases its elastic potential energy, causing the dust cover to automatically reset and close. This ensures that the interface is always in a closed state when idle, effectively preventing dust and debris from entering the interface. This solves the problem of poor interface contact and decreased transmission performance caused by dust accumulation, and improves the stability and service life of the optical module transmission terminal interface.
[0023] 2. In this utility model, the pressing handle drives the pressing column to slide downward, the pressing column drives the trapezoidal column to move downward, and the trapezoidal column pushes the locking ball to retract into the hollow cylinder, releasing the locking ball from the first protective frame. Then, by lifting the second protective frame upward, the protective shell can be removed, thus enabling maintenance personnel to conveniently inspect and maintain the internal components of the terminal module. This simplifies the disassembly process, solves the problem of complex, time-consuming, and labor-intensive disassembly of traditional protective shells, and improves the convenience and efficiency of optical module transmission terminal maintenance.

[0031] 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.
[0032] Reference Figures 1-5 This utility model provides an embodiment of a low-power high-speed optical module transmission terminal, including a module body 1, which carries the core circuit and data transmission components of the optical module. A protective frame 1 2 is fixedly connected to the top of the module body 1, which provides basic protection and supports the upper structure. A protective frame 2 3 is provided on the top of the protective frame 1 2, which enhances the overall protection and facilitates disassembly. A heat dissipation window 4 is provided inside the protective frame 2 3, which accelerates the dissipation of internal heat to improve the stability of the module. A fixed frame 6 is fixedly connected to the outer wall of the protective frame 1 2, which is used to fix the support structure of the dustproof component. A fixed column 8 is fixedly connected inside the fixed frame 6, which provides a rotation axis to realize the opening and closing of the dustproof cover 5. A circular frame 9 is fixedly connected to the outer wall of the fixed column 8, which is used to connect the torsion spring 7 and guide the movement trajectory of the dustproof cover 5. A dustproof component is provided at the bottom of the circular frame 9, which prevents dust from entering the interface and keeps it clean.
[0033] The dustproof component includes a dust cover 5, which is used to directly seal the optical module interface to prevent contamination. The top of the dust cover 5 is fixedly connected to the bottom of the circular frame 9. A torsion spring 7 is sleeved on the outer wall of the circular frame 9. The torsion spring 7 is used to provide elastic restoring force to realize the automatic closing of the dust cover 5. One end of the torsion spring 7 is fixedly connected to the outer wall of the fixed frame 6, and the other end of the torsion spring 7 is fixedly connected to the top of the dust cover 5. A hollow cylinder 10 is fixedly connected inside the second protective frame 3. The hollow cylinder 10 is used to accommodate the buckle assembly to realize the quick assembly and disassembly of the second protective frame 3. The buckle assembly is provided inside the hollow cylinder 10. The buckle assembly is used to lock the second protective frame 3 and release it for maintenance when needed.
[0034] Reference Figures 1-5The snap-fit assembly includes a snap-fit ball 11, which is used to engage and fix the protective frame 2. The snap-fit ball 11 is slidably connected inside the hollow cylinder 10, which provides a sliding track for the snap-fit ball 11 and limits its range of movement. The outer wall of the snap-fit ball 11 engages with the protective frame 2, thereby achieving quick locking of the protective frame 3. A trapezoidal post 12 is slidably connected inside the hollow cylinder 10. The trapezoidal post 12 is used to push the snap-fit ball 11 out of the engaged state. The trapezoidal post 12 is in contact with the snap-fit ball 11, and the extension and retraction of the snap-fit ball 11 is controlled by the inclined surface contact. A fixing plate 13 is fixedly connected inside the hollow cylinder 10. The fixing plate 13 is used to support the pressing post 14 and provide an installation position for the compression spring 15. The fixing plate 13 has a sliding surface inside. A pressing post 14 is connected to the movable connection. The pressing post 14 is used to transmit operating force to trigger the release of the buckle. The bottom of the pressing post 14 is fixedly connected to the top of the trapezoidal post 12. A pressing handle 17 is fixedly connected to the top of the pressing post 14. The pressing handle 17 is used to provide a force application point for manual operation. A sliding plate 16 is fixedly connected to the outer wall of the pressing post 14. The sliding plate 16 is used to maintain the stable sliding of the pressing post 14. The sliding plate 16 is slidably connected to the inner wall of the hollow cylinder 10. A compression spring 15 is sleeved on the outer wall of the pressing post 14. The compression spring 15 is used to provide a reset spring force to restore the buckle assembly to the locked state. One end of the compression spring 15 is fixedly connected to the bottom of the sliding plate 16, and the other end of the compression spring 15 is fixedly connected to the top of the fixed plate 13.
[0035] Working principle: When the optical module transmission terminal interface is needed, external force is applied to the dust cover 5, causing it to rotate around the fixed post 8. At this time, the torsion spring 7 is compressed, storing elastic potential energy, and the dust cover 5 opens to expose the interface. When the interface is no longer in use, the external force is removed, the torsion spring 7 releases its elastic potential energy, and the dust cover 5 rotates in the opposite direction around the fixed post 8 until the dust cover 5 returns to its original position and closes. This ensures that the interface is always in a closed state when not in use, effectively preventing dust and debris from entering the interface. When it is necessary to remove the protective frame 2 3 to inspect the internal components of the terminal module, press the pressing handle 17. The pressing handle 17 causes the pressing post 14 to slide down. When the press column 14 moves, it drives the trapezoidal column 12 to move downward. The trapezoidal column 12 pushes the locking ball 11 to retract into the hollow cylinder 10, releasing the locking ball 11 from the locking state of the first protective frame 2. At this time, the second protective frame 3 can be removed by lifting it upward. After the maintenance is completed, the second protective frame 3 is aligned with the first protective frame 2 and pressed. Under the action of the inclined surface of the trapezoidal column 12, the locking ball 11 first retracts into the hollow cylinder 10. When it reaches the locking position, the compression spring 15 pushes the sliding plate 16 to move upward. The sliding plate 16 drives the press column 14 and the trapezoidal column 12 to move upward. Under its own elasticity, the locking ball 11 pops out and locks with the first protective frame 2, completing the installation of the second protective frame 3.
