Description

Technical Field

[0001] The utility model relates to the technical field of optical fiber distribution, and specifically, to a full-size universal high-density distribution board for a MODF distribution frame. Background Art

[0002] An optical fiber distribution frame is a wiring connection device between an optical cable and an optical communication device or between optical communication devices, and is used for the termination and distribution of the central office backbone optical cable in an optical fiber communication system. It can conveniently realize the connection, distribution, and scheduling of optical fiber lines. With the increasing degree of network integration, an optical-digital hybrid distribution frame integrating ODF, DDF, and power distribution units has emerged, which is suitable for small and medium-sized wiring systems such as fiber to the community, fiber to the building, remote modules, and wireless base stations.

[0003] After retrieval, the "optical fiber distribution frame for a control cabinet" disclosed in Chinese Patent Publication No. CN216351433U includes: a distribution board installed at the wiring terminal of a signal box. A plurality of matrix-arranged insertion holes are formed on the distribution board, and the insertion holes are used for connecting optical fiber connectors. Installation grooves corresponding to the insertion holes one by one are formed on the distribution board, and the installation grooves are located on one side of the insertion holes; a corresponding number of swing plates are hinged in the corresponding installation grooves, and two pairs of wire clamping columns are arranged on one side end surface of each swing plate, and a clamping groove for clamping an optical fiber is formed between a pair of wire clamping columns.

[0004] This patent makes it convenient for personnel to manage wires by ensuring that the horizontal and vertical positions of the optical fibers drooping after being connected to the insertion holes of different heights are not on the same horizontal plane. However, there are some technical defects in the implementation of this type of patent:

[0005] First, during wiring, since the length of the optical fiber generally has a surplus, and after wiring is completed, if the excess optical fibers are not sorted out, they will be entangled with each other, which will cause difficulties for subsequent replacement and maintenance.

[0006] Second, after the distribution frame is installed on the equipment rack, the gap between the distribution frame and the inner wall of the equipment rack is small, and the operation space is limited when inserting the optical fiber connector. Not only is the operation inconvenient, but the optical fiber at the optical fiber connector will be bent greatly and is easy to break.

[0007] Third, the size of the distribution frame itself is fixed, while the sizes of different equipment racks vary, which makes the distribution frame unable to adapt to some equipment racks, and thus this patent has certain limitations. In view of this, the utility model proposes a full-size universal high-density distribution board for a MODF distribution frame. Summary of the Utility Model

The plurality of card slots 11 are equidistantly distributed along the length direction of the distribution frame 1. Coil holders 6 for winding excess cables are fixedly connected to both ends of the bottom of the distribution frame 1. Flipping assemblies 7 are provided at both ends of the distribution frame 1.

By clamping different numbers of MPO module boxes 2, MPO adapter panels 3, and LC adapter panels 8, different-density fiber optic wiring requirements can be met. Additionally, the cable management coil 6 can wind and organize the redundant cables, thus avoiding the problem of redundant cables winding around each other. Moreover, cable management coils 6 are provided at both ends of the wiring rack 1, so that when the cables are routed through either end of the wiring rack 1, they can be wound and organized by the cable management coils 6, with strong versatility.

[0035] Further, the wire member 5 includes a bracket 51, the bracket 51 is fixedly connected to one side of the wiring rack 1, one end of the bracket 51 is fixedly connected with a plurality of wire rods 52, one end of each of the plurality of wire rods 52 is fixedly connected with a limit block 53, a plurality of wire outlet grooves 12 are formed at the bottom of the wiring rack 1, and the plurality of wire outlet grooves 12 correspond to the card slots 11 one by one. A blanking plate 4 is clamped in the vacant card slot 11. The wire rods 52 can guide the cables, the limit blocks 53 can prevent the cables on the wire rods 52 from detaching from the wire rods 52, and the blanking plate 4 can block the vacant card slot 11 to achieve a dust-proof effect.

[0036] Further, the flipping assembly 7 includes a first fixed ear plate 7a1, both ends of the first fixed ear plate 7a1 are provided with first fixing bolts 7a2, the first fixed ear plate 7a1 is fixedly connected to the wiring rack 1 through the two first fixing bolts 7a2, the bottom end of the first fixed ear plate 7a1 is rotatably connected to a first flipping ear plate 7a3 through a pin shaft, the first flipping ear plate 7a3 is fixedly connected to the equipment rack, a first screw hole 7a5 is formed at one end of the first flipping ear plate 7a3, and a first spring bolt 7a4 passing through the wiring rack 1 is rotatably connected to the bottom end of the wiring rack 1, and the threaded end of the first spring bolt 7a4 can be threadedly engaged with the first screw hole 7a5.

A nut 7c33 is fixedly connected to the end of the smooth portion 7c32 away from the screw rod 7c31.

[0043] By fixedly connecting the L-shaped ear plate 7c1 to the end of the distribution frame 1, due to the right-angle structure of the L-shaped ear plate 7c1, the distribution frame 1 can be installed on the inner wall of the equipment rack perpendicular to the distribution frame 1 and fixedly connected to the equipment rack through the screw 7c31. Since the smooth part 7c32 is rotatably connected to the L-shaped ear plate 7c1, the L-shaped ear plate 7c1 can be flipped relative to the equipment rack, so that the gap between the distribution frame 1 and the equipment rack is increased to expand the operation space, thereby facilitating the wiring work for personnel. After the wiring is completed, the distribution frame 1 is fixedly connected to the equipment rack through the third spring bolt 7c4, so that the distribution frame 1 is kept fixed during operation, and the distribution frame 1 is kept stable during work.
