Description

Technical Field

[0001] The utility model relates to the technical field of optical fibers, and more particularly to an optical fiber slip ring tail cable buffer structure. Background Art

[0002] A fiber optic rotary joint (FORJ) is a device used to transmit optical signals between rotating components. It is widely used in equipment requiring continuous rotation and signal transmission, such as radar systems, medical imaging equipment, robots, drones, and wind turbines. Fiber optic slip rings transmit signals via optical fibers, offering advantages such as high transmission rates, immunity to electromagnetic interference, and minimal signal loss. They are key components in modern high-speed data transmission and rotary connections.

[0003] In the practical application of fiber optic slip rings, the pigtail cable (the fiber optic cable connected to the slip ring) is a critical component. One end of the pigtail cable connects to the fiber optic slip ring connector, and the other end connects to an external fiber optic line or device. However, in actual use, the pigtail cable's connector (where the optical fiber connects to the slip ring) is often subject to frequent rotation, bending, and twisting. This frequent mechanical movement poses a severe challenge to the reliability of the fiber optic connector and pigtail cable. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a fiber optic slip ring tail cable buffer structure, which includes a rotor housing and a stator housing connected together, a tail cable sheath is installed at the ends of the rotor housing and the stator housing away from each other, an optical fiber extending outward is inserted into the tail cable sheath, and a buffer structure is provided on the outside of the connection between the optical fiber and the tail cable sheath, and the buffer structure twists as the optical fiber bends and twists.

[0005] In a preferred embodiment, the buffer structure includes a threaded spring sleeved on the outside of the optical fiber, the end of the threaded spring is fixed to the end of the tail cable sheath, and a metal fixing ring is fixedly installed at the end of the threaded spring away from the tail cable sheath.

[0006] In a preferred embodiment, a rubber hose is sheathed on the outside of the threaded spring, and two ends of the rubber hose are respectively connected to the metal fixing ring and the tail cable sheath.

[0007] In a preferred embodiment, a telescopic tube is sleeved on the outside of the rubber hose, and both ends of the telescopic tube are respectively connected to the metal fixing ring and the tail cable sheath.

[0008] The technical effects and advantages of this utility model are:

[0009] The utility model provides a buffer structure at the connection between the optical fiber and the tail cable sheath, and uses a threaded spring to provide protection when the optical fiber is bent, thereby protecting the optical fiber slip ring tail cable, preventing the optical fiber from breaking, improving the reliability of the optical fiber equipment, and reducing the failure rate.

[0013] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for specific applications.

[0014] like Figure 1-2 The optical fiber slip ring tail cable buffer structure 5 shown includes a rotor housing 1 and a stator housing 2 connected together, a tail cable sheath 3 is installed at the ends away from each other, an optical fiber 4 extending outward is inserted into the tail cable sheath 3, and a buffer structure 5 is provided on the outside of the connection between the optical fiber 4 and the tail cable sheath 3, and the buffer structure 5 twists as the optical fiber 4 bends and twists.

[0015] Based on the above, when in use, the buffer structure 5 is placed on the connection between the tail cable sheath 3 and the optical fiber 4. During the frequent rotation, bending and twisting of the optical fiber 4, the buffer structure 5 can be replaced to provide protection between the optical fiber 4 connector and the tail cable sheath 3 during frequent mechanical movements.

[0016] The buffer structure 5 includes a threaded spring 6 sleeved on the outside of the optical fiber 4. The end of the threaded spring 6 is fixed to the end of the tail cable sheath 3. A metal fixing ring 7 is fixedly installed at the end of the threaded spring 6 away from the tail cable sheath 3.

[0017] Based on the above, the threaded spring 6 has a certain elasticity, and when the optical fiber 4 is bent, it can provide protection for the bending of the optical fiber 4 and prevent the optical fiber 4 from breaking.

[0018] A rubber hose 8 is sheathed on the outside of the threaded spring 6 , and two ends of the rubber hose 8 are connected to the metal fixing ring 7 and the tail cable sheath 3 respectively.

[0019] Furthermore, when the threaded spring 6 is protecting the optical fiber 4 from bending, the threaded spring 6 will bend along with the bending of the optical fiber 4, and a gap will appear at the bending place. Therefore, a rubber hose 8 is sleeved on the outside of the threaded spring 6. The rubber hose 8 is elastic and can be stretched. When the threaded spring 6 bends along with the bending of the optical fiber 4, the rubber hose 8 is sleeved on the outside of the threaded spring 6 and deformed together, thereby blocking the gap when the threaded spring 6 is bent, and preventing external dust and debris from entering the inside of the threaded spring 6.

[0020] A telescopic tube 9 is sheathed on the outside of the rubber hose 8, and both ends of the telescopic tube 9 are connected to the metal fixing ring 7 and the tail cable sheath 3 respectively;

[0021] Furthermore, a telescopic tube 9 is sleeved on the outside of the rubber hose 8 to protect the soft rubber hose 8 and prevent external sharp objects from scratching the rubber hose 8, thereby further improving the protection effect.

[0022] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making any creative efforts should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in this utility model shall be implemented in accordance with conventional means in the field unless otherwise specified or limited.
