Description

Technical Field

[0001] This utility model is a fiber optic cable routing device for a computer, belonging to the field of computer science. Background Technology

[0002] In computer systems, optical fiber serves as a high-bandwidth, low-loss transmission medium, and its layout design directly impacts data transmission efficiency, system stability, and ease of maintenance. Optical fibers (especially single-mode fibers) have a minimum bending radius limitation (typically 10-20 times the fiber diameter; for example, the minimum static bending radius of a common 9 / 125μm single-mode fiber is approximately 10mm, and the dynamic bending radius is approximately 30mm). Excessive bending, compression, or tangling of the fiber must be avoided during layout. If the bending radius is less than the threshold, it can lead to significant attenuation of the optical signal due to macro-bending loss, or even fiber core breakage. For example, when wiring inside a chassis, the optical fiber should be bent gently along the chassis bracket or cable tray, and should not be directly folded or compressed into gaps between components. After the optical fiber is fully arranged along the internal channel of the cable tray, it needs to exit from the corresponding cable port according to the location of the target device and then extend to the device interface. Although the cable tray provides a channel for the optical fiber to exit, the edges of the cable port are mostly right angles or narrow sides, and the diameter of the cable port must be adapted to the outer diameter of the optical fiber (to prevent the optical fiber from shaking). This means that when the optical fiber exits from inside the cable tray, the section near the cable port needs to suddenly turn from the gentle path inside the cable tray towards the device outside the cable port. If there is a large angle between the direction of the connection between the device interface and the cable port and the direction of the optical fiber arrangement inside the cable tray, the optical fiber will bend sharply at the cable port. Especially when the optical fiber needs to be led out from the cable port in a direction perpendicular to the cable tray, the degree of bending will be significantly aggravated, far exceeding the safe bending range of the optical fiber itself. If the fiber optic cable is bent at the cable entry point for a long time, even if there is no obvious fault at the beginning, it will gradually be damaged during long-term use (such as equipment vibration and temperature changes), resulting in a decrease in link stability. Moreover, the fault point is concentrated near the cable entry point, and the wiring around the cable tray needs to be disassembled to locate the fault during troubleshooting, which increases maintenance time and cost. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a computer fiber optic routing device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a computer fiber optic routing device, comprising:

[0005] The cable tray has a U-shaped cross-section, and multiple evenly arranged cable openings are provided on both parallel sides of the cable tray.

[0006] The bracket is installed in the cable tray. Both sides of the bracket facing the cable insertion port are machined with arc-shaped openings for inserting optical fibers. An arc-shaped plate for limiting the bending path of the optical fiber is rotatably installed at one end of the bracket. The arc-shaped plate has an L-shaped structure. The end of the arc-shaped plate away from the bracket is inserted into a cable insertion port. The end of the arc-shaped plate near the bracket is arranged concentrically with the arc-shaped opening.

[0007] Furthermore, multiple plug-in rods are evenly installed on the lower surface of the bracket, and multiple plug-in holes that mate with the plug-in rods are recessed on the upper surface of the bracket. The plug-in rods are glued into the corresponding plug-in holes, and the plug-in rods on the lowest bracket are glued to the inner wall of the cable tray.

[0008] Furthermore, a blind hole is formed at the position where the connector rod is installed on the bracket, and one end of the connector rod is installed in the blind hole.

[0009] Furthermore, a connecting plate is fixedly connected to one end of the arc-shaped plate near the support, and a connecting shaft is installed in the middle of the side of the support near the arc-shaped plate. The connecting shaft passes through the connecting plate and is rotatably connected to the connecting plate. The connecting plate maintains a constant relative position with the support through positioning screws.

[0010] Furthermore, one side of the connecting plate has a small hole that is offset from the connecting shaft, and the side of the support facing the connecting plate has two screw holes that are symmetrically arranged about the connecting shaft. The two screw holes are arranged vertically, and one end of the positioning screw passes through the small hole and is threaded into the corresponding screw hole.

[0011] Furthermore, a first retaining strip is installed at the top of the portion of the cable tray where the cable pass-through opening is processed. A strip-shaped slit is processed at the top of the cable pass-through opening, and the strip-shaped slit passes through the first retaining strip. A cover plate is provided at the portion of the cable tray where the first retaining strip is installed. The cover plate has a U-shaped cross-section. A second retaining strip is installed on each of the two parallel sides of the cover plate, and the second retaining strip is engaged with the first retaining strip.

[0012] Furthermore, the first snap-fit ​​strip and the wiring groove are integrally formed, and the second snap-fit ​​strip and the cover plate are integrally formed.

[0013] Furthermore, multiple waist-shaped holes and multiple fixing holes are provided on the side of the cable tray adjacent to the cable insertion port, and the waist-shaped holes and fixing holes are arranged alternately.

[0014] The beneficial effects of this utility model are:

[0015] The bracket has an arc-shaped opening on its side facing the cable insertion port, and the end of the arc-shaped plate closest to the bracket is concentrically arranged with the arc-shaped opening. When the optical fiber is arranged along the cable tray, it first passes through the arc-shaped opening of the bracket, and then is guided by the arc-shaped plate to exit from the cable insertion port. The curved surface structure of the arc-shaped opening provides an initial smooth transition for the optical fiber, while the arc-shaped plate further restricts the bending path of the optical fiber. This ensures that when the optical fiber is led out from inside the cable tray to the outside of the cable insertion port, it forms a smooth curve that conforms to the safe bending radius, avoiding the sharp bending caused by the right-angle edge of the traditional cable insertion port. Even if there is a large angle between the connection direction of the equipment interface and the cable insertion port, the optical fiber can slowly turn with the guidance of the arc-shaped plate, without bending far beyond the safe range. This effectively reduces macro-bending loss, prevents optical signal attenuation or fiber core breakage, and ensures the stability of data transmission and the lifespan of the link.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Please see Figures 1-3This utility model provides a technical solution: a fiber optic cable routing device for a computer, including a cable tray 1 with a U-shaped cross-section. Multiple evenly arranged cable entry ports 11 are provided on both parallel sides of the cable tray 1. Multiple oblong holes 14 and multiple fixing holes 15 are provided on the side of the cable tray 1 adjacent to the cable entry ports 11, with the oblong holes 14 and fixing holes 15 arranged alternately. A first retaining strip 12 is installed at the top of the portion of the cable tray 1 where the cable entry ports 11 are processed. The first retaining strip 12 is integrated with the cable tray 1. The cable tray 1 has a monolithic structure with a strip-shaped slot 13 machined at the top inside the cable entry 11. The strip-shaped slot 13 passes through the first snap-fit ​​strip 12. The cable tray 1 has a cover plate 3 at the part where the first snap-fit ​​strip 12 is installed. The cover plate 3 has a "U" shaped cross-section. The cover plate 3 has a second snap-fit ​​strip 31 installed on each of its two parallel sides. The second snap-fit ​​strip 31 and the cover plate 3 are integrally formed, so that the second snap-fit ​​strip 31 and the first snap-fit ​​strip 12 are snapped together, completing the assembly of the cover plate 3 and the cable tray 1, thereby hiding the optical fiber in the space formed by the cover plate 3 and the cable tray 1.

[0027] See Figures 1-4 The bracket 2 is installed in the cable tray 1. The bracket 2 has arc-shaped openings 25 for inserting optical fibers on both sides facing the cable opening 11. An arc-shaped plate 21 for limiting the bending path of the optical fiber is rotatably installed on one end of the bracket 2. The arc-shaped plate 21 has an L-shaped structure. The end of the arc-shaped plate 21 away from the bracket 2 is inserted into a cable opening 11. The end of the arc-shaped plate 21 close to the bracket 2 is arranged concentrically with the arc-shaped opening 25. The side of the bracket 2 facing the cable opening 11 has an arc-shaped opening 25, and the end of the arc-shaped plate 21 close to the bracket 2 is arranged concentrically with the arc-shaped opening 25. When the optical fiber is arranged along the cable tray 1, it first passes through the arc-shaped opening 25 of the bracket 2, and then is guided by the arc-shaped plate 21 to pass out from the cable opening 11. The curved structure of the arc-shaped opening 25 provides an initial smooth transition for the optical fiber, while the arc-shaped plate 21 further restricts the bending path of the optical fiber. This allows the optical fiber to form a smooth curve that conforms to the safe bending radius when it is led out from inside the cable tray 1 to the outside of the cable opening 11. This completely avoids the sharp bending caused by the right-angle edge of the traditional cable opening 11. Even if there is a large angle between the connection direction of the device interface and the cable opening 11, the optical fiber can slowly turn with the guidance of the arc-shaped plate 21, without bending far beyond the safe range. This effectively reduces macro bending loss, prevents optical signal attenuation or fiber core breakage, and ensures the stability of data transmission and the lifespan of the link.

[0028] See Figures 1-4Multiple connector rods 24 are evenly installed on the lower surface of the bracket 2. Multiple connector holes 26 are recessed on the upper surface of the bracket 2 to mate with the connector rods 24. The connector rods 24 on the upper bracket 2 are inserted into the connector holes 26 on the lower bracket 2. The connector rods 24 are glued to the corresponding connector holes 26. The connector rods 24 on the lowest bracket 2 are glued to the inner wall of the cable tray 1. Blind holes are formed at the locations where the connector rods 24 are installed on the bracket 2, allowing the connector rods 24 to be inserted into the cable tray 1. The end is installed in the blind hole to increase the stability of the connection between the plug rod 24 and the bracket 2. The plug rod 24 on the lower surface of the bracket 2 can cooperate with the plug hole 26 of the upper bracket 2. Multi-layer stacking can be achieved by fixing with glue. When multiple optical fibers need to be arranged in the cable tray 1, the optical fibers can be placed on different levels of brackets 2. Each optical fiber is independently led out through the arc-shaped opening 25 and arc-shaped plate 21 of the corresponding bracket 2, avoiding the path confusion caused by the tangling and squeezing of optical fibers in traditional single-layer cabling.

[0029] See Figure 1 , Figure 3 and Figure 4 A connecting plate 22 is fixedly connected to one end of the curved plate 21 near the support 2. A connecting shaft is installed in the middle of the side of the support 2 near the curved plate 21. The connecting shaft passes through the connecting plate 22 and is rotatably connected to the connecting plate 22. The connecting plate 22 is kept in a fixed relative position to the support 2 by a positioning screw 23. One side of the connecting plate 22 has a small hole that is offset from the connecting shaft. The side of the support 2 facing the connecting plate 22 has two screw holes that are symmetrically arranged about the connecting shaft. The two screw holes are arranged vertically. One end of the positioning screw 23 passes through the small hole and is threaded into the corresponding screw hole. The curved plate 21 is rotatably connected to the support 2 by the connecting shaft of the connecting plate 22. Loosening the positioning screw 23 can adjust the angle of the curved plate 21. When the optical fiber needs to be led out in different directions, the curved plate 21 can be rotated so that the end away from the support 2 is adapted to the position of the cable insertion port 11, while maintaining the concentric relationship between the curved plate 21 and the curved port 25 to ensure that the bending path is always gentle. After adjustment, the positioning screw 23 is passed through the small hole of the connecting plate 22 and screwed into the corresponding screw hole to fix the position of the arc plate 21. It can be adapted to various export scenarios without replacing parts, avoiding the problem of fiber bending caused by the fixed export direction and improving versatility.
