Description

Technical Field

[0001] This utility model relates to the field of optical rotating slip ring technology, and in particular to a micro optical rotating slip ring structure. Background Technology

[0002] In optical rotating slip ring applications, the connection between the optical fiber and the slip ring often lacks adequate protection mechanisms. Optical fibers, especially their exposed, stripped sections, are extremely fragile and prone to breakage or bending under tension or pressure. Particularly in confined installation environments, the connection point between the fiber and the slip ring is more susceptible to pressure from surrounding structures, causing the fiber's bending radius to fall below its minimum allowable range. This leads to signal attenuation or even transmission interruption. This not only severely impacts signal stability but also accelerates the aging process of the optical fiber, shortening its lifespan.

[0003] Although some improvements have been made, such as the fiber optic slip ring disclosed in Chinese utility model patent application number 202320744244.5, which adds a fixing sleeve to the outside of the fiber optic segment, in practical applications, this fixing method still easily causes significant bending at the connection between the fiber optic segment and the fixing sleeve when subjected to external pressure. This phenomenon is not uncommon in daily life; similar to the USB cable of a mobile phone charger, the connection point with the charging head often suffers damage or breakage due to frequent bending and compression.

[0004] In view of the above problems, this utility model proposes an innovative micro-optical rotating slip ring structure, which aims to solve the problem of optical fiber being easily damaged. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a miniature optical rotating slip ring structure to solve the above problems.

[0006] To achieve the above objectives, this utility model provides a miniature optical rotating slip ring structure, comprising a slip ring body, with both ends of the slip ring body for connecting optical fibers. The slip ring body is characterized by having optical fiber protection mechanisms at both ends. Each optical fiber protection mechanism includes two semi-circular fixing blocks detachably fixed to the ends of the slip ring body. The optical fiber is clamped between the two semi-circular fixing blocks. Two anti-bending rubber blocks are fixed to the upper ends of the two semi-circular fixing blocks, and the openings of the anti-bending rubber blocks are rounded.

[0007] Preferably, two semi-circular rubber blocks for clamping the optical fiber are fixed inside the two semi-circular fixing blocks.

[0008] Preferably, two mounting blocks are symmetrically fixed on both sides of the end of the slip ring body. The mounting blocks are provided with threaded holes, and the semi-circular fixing blocks are inserted with connecting bolts. The connecting bolts are threadedly connected to the threaded holes.

[0009] Preferably, the mounting block has a rectangular structure, and a rectangular guide groove is embedded in the inner bottom of the semi-circular fixing block, and the mounting block is slidably disposed in the rectangular guide groove.

[0010] Compared with the prior art, this invention has the following advantages: In the prior art, optical fibers are prone to breakage or damage at the connection point of the optical rotating slip ring due to excessively small bending radius, or they may be pulled apart due to excessive force during clamping. This invention, through the design of an optical fiber protection mechanism, including a detachable semi-circular fixing block and an anti-bending rubber block, and the setting of the semi-circular rubber block, achieves effective protection and stable clamping of the optical fiber. It not only limits the bending radius of the optical fiber, preventing it from breaking or damaging the insulation, but also disperses the clamping force, avoiding the risk of the optical fiber being pulled apart. Attached Figure Description

[0017] The following is in conjunction with the appendix Figure 1-4 The specific embodiments of this utility model will be described in further detail.

[0018] like Figure 1-4As shown, this utility model discloses a miniature optical rotating slip ring structure, including a slip ring body 1. Both ends of the slip ring body 1 are used to connect optical fibers 2. Optical fiber protection mechanisms 3 are provided at both ends of the slip ring body 1. The optical fiber protection mechanism 3 includes two semi-circular fixing blocks 31 detachably fixed to the ends of the slip ring body 1. The optical fiber 1 is clamped between the two semi-circular fixing blocks 31. The two semi-circular fixing blocks 31 clamp the optical fiber 2, effectively preventing it from loosening. Furthermore, by clamping the optical fiber 2 with the two semi-circular fixing blocks 31, the core of the optical fiber 2 can be prevented from being broken when subjected to external force. Further, two anti-bending rubber blocks 32 are fixed to the upper ends of the two semi-circular fixing blocks 31. The openings of the anti-bending rubber blocks 32 are rounded, which can limit the bending radius of the optical fiber 2 to not be lower than the minimum allowable value, thereby effectively slowing down the aging rate of the optical fiber 2.

[0019] In some embodiments, two semi-circular rubber blocks 33 for clamping the optical fiber 2 are fixed inside the two semi-circular fixing blocks 31. By clamping the optical fiber 2 with the semi-circular rubber blocks 33, the friction between the semi-circular fixing blocks 31 and the optical fiber 2 can be increased, further preventing the optical fiber 2 from becoming loose, and the semi-circular rubber blocks 33 can prevent the optical fiber 2 from being damaged by clamping.

[0020] Please refer to Figure 1 and 4 Two mounting blocks 11 are symmetrically fixed on both sides of the end of the slip ring body 1. The mounting blocks 11 are threaded through, and the semi-circular fixing blocks 31 are inserted through with connecting bolts 34. The connecting bolts 34 are threadedly connected to the threaded holes. After connecting the optical fiber 2 to the slip ring body 1, the two semi-circular fixing blocks 31 are fixed to the two mounting blocks 11 by the connecting bolts 34, so that the optical fiber 2 can be clamped between the two semi-circular fixing blocks 31, which is easy to operate.

[0021] For easier installation of the semi-circular fixing block 31, please refer to... Figure 4 The mounting block 11 has a rectangular structure. A rectangular guide groove 35 is embedded in the bottom inner side of the semi-circular fixing block 31. The mounting block 11 is slidably disposed in the rectangular guide groove 35. By setting the rectangular guide groove 35, the mounting block 11 can be limited to the inner side of the semi-circular fixing block 31. In this way, after the optical fiber 2 is installed, the semi-circular fixing block 31 can be pushed to move at the end of the slip ring body 1 and close to the optical fiber 2 by rotating the connecting bolt 34, thereby clamping the optical fiber 2.

[0022] In summary, this utility model aims to realize a miniature optical rotating slip ring with an optical fiber protection structure. By clamping the optical fiber 2 with two detachable semi-circular fixing blocks 31, the optical fiber 2 is effectively prevented from loosening or breaking of the inner core. At the same time, the anti-bending rubber block 32 limits the bending radius of the optical fiber 2 to above the minimum allowable value, thereby slowing down the aging speed of the optical fiber 2. Thus, it effectively solves the problem that the optical fiber is easily broken by pulling and easily bent by compression in the existing optical rotating slip ring.

[0023] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
