Description

Technical Field

[0001] The utility model relates to the field of optical fiber jumpers, in particular to an optical fiber jumper fixing device. Background Art

[0002] Fiber optic patch cords are used to connect devices to fiber optic cabling links. They have a thicker protective layer and are generally used to connect optical terminals and terminal boxes. They are used in fiber optic communication systems, fiber optic access networks, fiber optic data transmission, and local area networks.

[0003] Fiber optic patch cords are optical cables with connector plugs installed at both ends to achieve active connection of the optical path: the one with a plug is called a pigtail. Fiber optic patch cords are similar to coaxial cables, but without the mesh shielding layer. The center is the glass core where the light propagates. In multimode optical fiber, which is roughly the thickness of a human hair, the core is surrounded by a glass envelope with a lower refractive index than the core to keep the fiber inside the core. Outside of this is a thin plastic jacket to protect the envelope.

[0004] During the installation and use of traditional fiber optic patch cords, it is impossible for the length size to be just right, and there is often a certain amount of redundancy. For these extra fiber optic patch cords, if they are not fixed and protected, it will not only affect the appearance, but also the optical fiber is very easy to be damaged, which will cause the use and transmission efficiency of the fiber optic patch cord to be greatly reduced, and it cannot meet the use needs of personnel. For this reason, we propose a fiber optic patch cord fixing device. Utility Model Content

The fixed rod 6 is welded inside the fixed box 1.

[0030] Furthermore, a horizontal partition 14 is provided inside the tensioning box 3, and the motor 9 can be placed on the part of the tensioning box 3 that is away from the slide groove 7.

[0033] Working principle: The optical fiber jumper fixing device is correctly installed according to the diagram, and the flip cover 2 is flipped through the handle 24 and the connecting hole 1 23. At this time, the front and top of the fixing box 1 are opened, and the optical fiber jumper is inserted into the fixing box 1 through the wire inlet hole 11, bypasses the bottom of the fixed pulley 1 26, and then continuously bypasses the rotating parts 4 on the two sets of fixed rods 1 6 in the fixing box 1. At this time, the fixed rod 21 of the tightening slider 5 is flush with the fixed rod 1 6, so the optical fiber jumper also passes through the fixed rod 21, and finally passes through the fixed pulley 27 to pass through the wire outlet hole. 12. When the two ends of the optical fiber jumper outside the optical fiber jumper fixing device are connected, start the motor 9. The rotating shaft of the motor 9 is a threaded shaft, which drives the tensioning slider 5 to move vertically upward. At this time, the optical fiber jumper wound on the fixing rod 21 of the tensioning slider 5 is pulled upward. When the optical fiber jumper wound inside the fixing box 1 reaches a suitable tension, the fixing work of the optical fiber jumper is completed, and the flip cover 2 is flipped over to completely cover the fixing box 1, or it is fixed with suitable bolts through the connecting hole 25 and the connecting hole 3 28.
