Description

Technical Field

[0001] This utility model relates to the field of fiber optic patch cord technology, specifically to a fiber optic patch cord redundancy switching protection device. Background Technology

[0002] Fiber optic patch cords are optical cables with connectors at both ends, used to make active connections in the optical path. They are used as patch cords from equipment to fiber optic cabling links, have a thick protective layer, and are generally used for connections between optical transceivers and terminal boxes.

[0003] Existing technologies, such as CN218213565U, describe a fiber optic patch cord protection device. This utility model uses a top cover for repairing and replacing fiber optic patch cords, facilitating internal fiber optic patch cord maintenance. Multiple sets of round holes allow fiber optic patch cords to be hung in different positions, ensuring the stability of the protection device.

[0004] However, this device still has some shortcomings in its use:

[0005] 1. Because the optical fiber is installed inside the protective device, and the device cannot effectively fix the optical fiber, the optical fiber is prone to displacement inside. Relying solely on spacers for fixation has limitations, which not only reduces the practicality of the optical fiber but also affects its safety.

[0006] 2. When the position of the optical fiber moves too much, it can not only affect the normal transmission of the optical fiber, but may even damage the optical fiber. The protection device also has certain deficiencies in redundancy switching, which affects the reliability of the communication system. Utility Model Content

Because the fiber optic cable is installed inside the protection device, and the device cannot effectively fix the fiber optic cable, the fiber optic cable is prone to positional displacement inside. Relying solely on spacers for fixation has limitations, which not only reduces the practicality of the fiber optic cable but also affects its safety. When the fiber optic cable moves too much, it can easily affect the normal transmission of the fiber optic cable and may even damage the fiber optic cable. The protection device also has certain shortcomings in redundancy switching, which affects the reliability of the communication system.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A fiber optic patch cord redundancy switching protection device includes a protective housing. A fixing assembly is located on the top of the protective housing. The fixing assembly includes a mounting plate snapped onto the top of the protective housing, a threaded cylinder on the top of the mounting plate, a threaded rod threadedly connected to the bottom of the threaded cylinder, and a fixing block fixedly connected to the end of the threaded rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. In this utility model, by using a combination of a threaded cylinder, a threaded rod, a hinged rod, a positioning block, a movable block, a shock-absorbing spring, and a guide plate, the problem of fiber optic patch cords easily shifting position inside the protection device is solved. The combined use of the threaded cylinder and the threaded rod can effectively fix the fiber optic patch cord and prevent it from shifting position. After the threaded rod moves downward, the hinged rod can drive the adjusting block to move towards the positioning block, thereby fixing the fiber optic cable and further stabilizing its position and improving its stability. The combined use of the movable block and the shock-absorbing spring can buffer the fiber optic patch cord when it is subjected to external impact and guide its direction, making it neater and more aesthetically pleasing.

[0019] 2. In this utility model, by using a combination of a fixing ring, a fixing rod, a moving block, a moving groove, and a protective pad, the threaded cylinder is rotatably connected to the fixing ring, making it easy for workers to adjust the threaded cylinder. The fixing rod is inserted into the fixing ring to fix the threaded cylinder and prevent it from rotating randomly, thus improving its practicality. Since the moving block extends into the moving groove and is slidably connected to the moving groove, the stability of the adjusting block is improved when it moves. Protective pads are fixedly connected to the sides of the positioning block and the adjusting block, which facilitates the protection of the surface of the fixed optical fiber.
