Description

Technical Field

[0001] This utility model relates to the field of optical cable transmission technology, and in particular to an optical cable connection device. Background Technology

[0002] In today's era of rapid digital information development, high-speed and stable information transmission is of paramount importance. As a key component of fiber optic communication systems, optical fiber connection devices bear the heavy responsibility of ensuring reliable connections and signal transmission between optical fibers. Their performance directly affects the operational quality and efficiency of the entire communication network.

[0003] Existing optical cable connection devices typically employ a modular design in terms of mechanical structure, mainly consisting of a housing, optical cable fixing device, optical fiber splice tray, and adapter mounting plate. The housing is generally made of metal or high-strength plastic to provide good physical protection. The optical cable fixing device securely fixes the optical cable to the housing using screws, clamps, etc., preventing damage to the internal optical fibers due to external pulling. The optical fiber splice tray is used to orderly store the optical fiber splices, and precise slots and clamps ensure that the spliced ​​optical fibers do not shift. The adapter mounting plate is equipped with various types of optical fiber adapters to connect the optical fiber to the communication equipment. Its technical principle is based on physical connection and optical alignment. Through precise mechanical positioning and fixing, it ensures the coaxiality and splice quality of the optical fiber during the connection process, enabling the optical signal to be stably transmitted from the optical cable to the communication equipment.

[0004] However, in some environments with high ambient temperatures, or when there are many fiber optic devices with high power inside the junction box, the junction box in the existing optical cable connection device is prone to generating a lot of heat. Due to the lack of efficient heat dissipation structures and methods, excessive heat accumulates inside the junction box, which will seriously affect the transmission performance of the optical fiber, causing problems such as signal attenuation and distortion. At the same time, it will also greatly shorten the service life of the equipment, posing a great challenge to the long-term stable operation of the communication system. Therefore, an optical cable connection device is proposed to solve the above problems. Utility Model Content

[0023] This utility model has the following beneficial effects:

[0024] 1.

[0032] 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.

[0033] Reference Figure 1 and Figure 2 The present invention provides an embodiment of an optical cable connection device, comprising a connection box 1. The connection box 1 is based on physical connection and optical alignment. Through precise mechanical positioning and fixing, it ensures the coaxiality and splicing quality of the optical fiber during the connection process, so that the optical signal can be stably transmitted from the optical cable to the communication equipment. A connection plate 2 8 is provided on one side of the connection box 1. A heat dissipation component and a quick-installation component are provided on the outer wall of the connection box 1. The heat dissipation component is used to quickly reduce the temperature of the connection box 1. The quick-installation component is used for convenient installation and disassembly of the connection box 1 and the connection plate 2 8.

[0034] The heat dissipation assembly includes multiple metal heat sinks 2. The metal heat sinks 2 increase the contact area with air through their wavy structure, thereby improving heat dissipation efficiency. The outer walls of the multiple metal heat sinks 2 are fixedly connected to both sides of the connecting box 1. The outer wall of each metal heat sink 2 has a wavy structure. Multiple connecting plates 3 are fixedly connected to the other two sides of the connecting box 1. The connecting plates 3 are used to fix the rotating strips 4 and provide support. Multiple rotating strips 4 are rotatably connected between adjacent metal heat sinks 2. The rotating strips 4 serve as the rotation axis of the fan blades 5. Multiple fan blades 5 are fixedly connected to the outer wall of each rotating strip 4. The fan blades 5 accelerate the airflow by rotating to enhance the heat dissipation effect. Limiting rings 6 are fixedly connected to both ends of each rotating strip 4. The limiting rings 6 prevent the rotating strip 4 from detaching from the connecting plate 3 during rotation. The limiting rings 6 are in contact with the connecting plate 3.

[0035] Reference Figure 1 , Figure 3 and Figure 4The quick-installation assembly includes multiple square locking blocks 17, which are quickly fixed by engaging with the fixing shell 11. The square locking blocks 17 are located on both sides of the connecting box 1. Connecting frames 7 are fixedly connected to both sides of the connecting box 1, supporting the connecting cylinder 9 and fixing its position. Each connecting frame 7 has a connecting cylinder 9 fixedly connected inside, serving as the moving space for the square locking blocks 17. The outer wall of each connecting cylinder 9 is slidably connected to the fixing shell 11, which is quickly installed by cooperating with the square locking blocks 17. The outer walls of the multiple fixing shells 11 are fixedly connected to the inside of the connecting plate 8. Each connecting cylinder 9 has a support plate 10 fixedly connected to its outer wall, used to fix and support the fixing ring 15. The inner wall of each support plate 10 is fixedly connected to the fixing ring 15, which restricts the movement range of the connecting post 12. The inner wall of each fixing ring 15 is slidably connected to the connecting post 12, which moves to drive the circular... The connecting block 16 enables engagement and disengagement. Each connecting post 12 has a truncated cone connecting block 16 fixedly connected to its bottom end. The truncated cone connecting block 16 is fixed by pushing the square locking block 17 through the inclined surface. The truncated cone connecting block 16 and the square locking block 17 are in close contact. The connecting cylinder 9 has multiple sliding grooves inside. The inner wall of the sliding groove has a structure that is larger in the middle and smaller on both sides. The sliding groove restricts the movement range of the square locking block 17. The two sides of each square locking block 17 have an arc structure. The arc structure of the square locking block 17 facilitates sliding inside the connecting cylinder 9. The square locking block 17 engages with the inside of the fixing shell 11. Each connecting post 12 has a spring 14 on its outer wall. The spring 14 resets the position of the truncated cone connecting block 16 through elastic force. The bottom end of each spring 14 is fixedly connected to the outer wall of the fixing ring 15. The top end of each spring 14 is fixedly connected to a connecting ring 13. The connecting ring 13 serves as the fixing point of the spring 14 and transmits pressure. The inner wall of each connecting ring 13 is fixedly connected to the outer wall of the connecting post 12.

[0036] Working principle: During the installation of the connecting box 1, the user places their finger on the bottom of the support plate 10 and presses down on the connecting ring 13. As the connecting ring 13 moves, it drives the frustum connecting block 16 to move out of the outer wall of the square locking block 17 through the connecting post 12, providing space for the square locking block 17 to move. Since the upper and lower sides of the square locking block 17 are arc-shaped and the inside of the connecting cylinder 9 is larger in the middle and smaller on both sides, the movement range of the square locking block 17 can be restricted, preventing the square locking block 17 from accidentally moving out of the inside of the connecting cylinder 9. During this process, the connecting ring 13 on the outer wall of the connecting post 12 will compress the spring 14. Next, the metal heat sink 2 is moved to one side of the connecting plate 8, and the connecting cylinder 9 is inserted into the inner wall of the fixed shell 11. Then, the pressure on the connecting ring 13 is released, and the rebound force of the spring 14 pushes the frustum connecting block 16 back to the outer wall of the square locking block 17. The inclined surface of the outer wall of the frustum connecting block 16 pushes the square locking block 17 to lock into the inner wall of the fixed shell 11, thereby fixing the position of the connecting box 1 and the connecting plate 2 8. When it is necessary to disassemble the connecting box 1, according to the same principle, the connecting cylinder 9 is moved out from the inner wall of the fixed shell 11, thereby disassembling the connecting box 1 and the connecting plate 2 8. This achieves the effect of installing and disassembling the connecting box 1, solving the problem that when the connecting box 1 needs to be repaired or the internal optical cable needs to be processed, it is necessary to use a special tool to unscrew the screws on the surface of the connecting box 1, which is time-consuming. This enhances the portability of installing and disassembling the connecting box 1.

[0037] During the heat dissipation process on the surface of the connector box 1, the metal heat sink 2 dissipates heat from the surface of the connector box 1 outwards. The wavy shape of the metal heat sink 2 enhances the contact area between the metal heat sink 2 and the air, allowing the heat on the surface of the connector box 1 to dissipate rapidly. At the same time, the airflow drives the fan blades 5 to rotate around the rotor 4, guiding external cool air to both sides of the connector box 1 and accelerating the airflow speed. This also accelerates the dissipation of heat from both sides of the connector box 1, thereby achieving the heat dissipation effect on the surface of the connector box 1. This solves the problem that in some high-temperature environments, or when there are many fiber optic devices with high power inside the connector box 1, excessive heat can easily be generated, which can affect the fiber optic transmission performance, shorten the service life of the equipment, or even lead to equipment failure. This improves the heat dissipation efficiency of the product.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
