Description

Technical Field

[0001] The invention relates to the field of optical fiber installation, in particular to a double-group optical fiber reel retaining plate bracket. Background Art

[0002] With the booming development of high-speed railways, the distance between cities is further shortened. The signal trough of electrified railways provides another way to lay optical cables. However, the vibration of high-speed railways is stronger than that of highways. Whether the optical cable (especially the joint) can ensure the stability of transmission performance is one of the important considerations. Unlike traditional optical fiber ribbon cables, ultra-high density and ultra-large core number optical fiber ribbon cables have high optical fiber volume ratio. In the cabling process, the new optical fiber ribbons must be bundled and arranged more densely. During manufacturing, installation, and environmental changes, the optical cable is subjected to tensile bending. The optical fiber in the cable is more likely to produce residual strain, and the optical cable is more likely to produce bending strain when it is bent. When the mesh optical fiber ribbon is cabled, it undergoes the optical fiber ribbon winding, bundling, and cabling processes, which optimizes the bending characteristics of the optical fiber ribbon and improves the residual strain and bending strain of the optical fiber ribbon in the cable. Therefore, the ultra-high density and ultra-large core count mesh optical fiber ribbon cable has a smaller outer diameter than traditional optical fiber ribbon cables of the same specification, and thus allows a smaller bending radius, which is more conducive to its manufacturing and installation applications. Therefore, the difficulties in the construction and maintenance of large-core count optical cables in existing high-speed rail ducts need to be urgently resolved. Summary of the invention

[0003] In view of the existing problems, the present invention provides a double-group optical fiber coil retaining plate bracket, which can effectively solve the problems raised in the background technology when used in combination.

[0004] To solve the above problems, the present invention adopts the following technical solutions:

[0005] A double-group optical fiber reel plate bracket comprises a joint box, a connecting bracket is installed inside the joint box, an optical fiber receiving mechanism is arranged above the connecting bracket, an optical fiber reel plate is arranged in the internal array of the optical fiber receiving mechanism, a wire pressing plate is installed on the inner side wall of the optical fiber reel plate, a top cover is installed above the optical fiber reel plate located at the uppermost end, an optical fiber reel sheet is installed in the internal axial array of the optical fiber reel plate, a cable clamping groove is provided inside the optical fiber reel sheet, threading holes are provided at the corners of the optical fiber reel plate, a self-locking buckle is installed on the front surface of the optical fiber reel plate, a rotating ring is installed on the upper position of the rear surface of the optical fiber reel plate, and a rotating shaft is installed on the rear surface of the optical fiber reel plate just below the rotating ring.

[0006] As a further solution of the present invention: a shock-absorbing pad is installed on the upper surface of the connecting bracket, a connecting screw hole is opened on the upper surface of the shock-absorbing pad, a side wire-pressing nut is installed on the side surface of the shock-absorbing pad, and a wiring harness pressure plate is installed on the side surface of the connecting bracket on both sides of the connecting screw hole.

[0007] As a further solution of the present invention: end support brackets are installed at both ends of the connecting bracket, the upper surface of the end support bracket is provided with a wire harness sleeve pressing piece, and the inner side of the end support bracket is installed with an end wire pressing nut.

[0008] As a further solution of the present invention: center wiring harness sleeves are installed at both axial ends of the junction box, side wiring harness sleeves are installed on both sides of the center wiring harness sleeve at both ends of the junction box, side strong cores are arranged inside the side wiring harness sleeves, and a middle strong core is arranged inside the center wiring harness sleeve.

[0009] As a further solution of the present invention: the rotating sleeve is movably connected to the rotating shaft, and the wire pressing plate is fixedly connected to the optical fiber reel retaining plate.

[0010] As a further solution of the present invention: the joint box is a component made of a mixed material of PC and ABS plastics.

[0011] As a further solution of the present invention: a connecting screw hole is provided on the lower surface of the optical fiber coil retaining plate at a position corresponding to the connecting screw hole.

[0012] As a further solution of the present invention: the shock-absorbing pad is fixed to the connecting bracket by glue, a clamping screw is installed on the upper surface of the connecting bracket below the end wire-pressing nut, and a clamping screw is installed on one side of the side wire-pressing nut on the outside of the shock-absorbing pad.

[0013] As a further solution of the present invention: a pan head cross bolt is connected between the wiring harness sleeve pressing piece and the end support bracket.

[0014] As a further solution of the present invention: the connection between the side harness sleeve and the center harness sleeve and the junction box is filled with sealing putty, and a threaded connection ear plate is installed on the side surface of the junction box.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. A multi-layer fiber optic coiling plate is arranged inside the fiber optic receiving mechanism as a whole. The fiber optic coiling plate is used in conjunction with the internal fiber optic coiling sheet to position and arrange the optical fiber. Therefore, the length of the remaining optical fiber inside and the curvature radius of the remaining optical fiber coil can be guaranteed.

[0017] 2. Two groups of optical fibers are arranged in opposite directions inside the connecting bracket, and can be wired in conjunction with the threading holes opened at both ends of the optical fiber plate to ensure the bending radius of the wiring. At the same time, the installed optical fiber receiving mechanism is arranged above the shock-absorbing pad to reduce the impact of the vibration generated by the operation of the vehicle after installation on the internal optical fiber.

[0018] 3. The connecting bracket can be used as a whole for the optical cable, the reinforcing core and the optical fiber receiving mechanism. The reinforcing core fixing position finally adopts the combination of the two sides and the middle, which makes the fixation of the reinforcing core more stable and the bending radius of the optical fiber bundle tube is better satisfied.

[0019] 4. The upper end of the self-locking buckle is a raised structure, and the lower end is an embedded structure, so it can be used to lock the upper and lower fiber optic trays. The rotating ring on one side of the upper fiber optic tray is integrally stuck inside the rotating shaft on the lower fiber optic tray, so the two layers of fiber optic trays can be quickly opened.
