Description

Technical Field

[0001] This utility model relates to a chassis structure, specifically a novel ODF chassis structure. Background Technology

[0002] The ODF (Optical Distribution Frame) is a core device in an optical fiber communication system. It is mainly used for optical cable termination, splicing, and patch cord management, enabling the connection, distribution, and scheduling of optical fiber lines.

[0003] Existing ODF (Optical Deposit Box) chassis have a complex structure and unreasonable design. Organizing the MPO connector cables mounted on the spindle inside the ODF chassis requires first opening the chassis and removing the spindle to the outside, then organizing the cables on the spindle outside, and finally reinstalling the spindle back into the ODF chassis. This process is multi-step, time-consuming, and labor-intensive, resulting in poor usability of the ODF chassis. Furthermore, the cables inside the ODF chassis, as well as those extending to the outside, cannot be well organized, often resulting in a tangled mess. The side panels of the ODF chassis require removing and installing screws, which is inconvenient. Therefore, the inventor has improved the structure of the ODF chassis. Utility Model Content

[0004] The purpose of this utility model is to provide a novel ODF chassis structure. This novel ODF chassis structure has the advantages of simple structure, reasonable design, and the ability to install the terminals at both ends of the MPO connector to the designated port positions without removing the spindle. The installation of the MPO connector is more convenient, time-saving, labor-saving, and easy to use. It also allows the MPO connector wires to be fixed in an orderly manner in the cavity of the chassis, without the wires becoming tangled. It enables quick disassembly and assembly between the top cover and the rear panel, and makes the use of optical fibers and subsequent maintenance more convenient. This solves the problems mentioned in the above-mentioned technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel ODF chassis structure, comprising a chassis and an optical fiber distribution mechanism disposed on the chassis. The chassis is a hollow cavity structure, and includes a tray and a top cover plate fixed to the tray. In this embodiment, the tray and the top cover plate are locked together by screws. A rear panel and a front panel are fixed on the tray, located at opposite ends of the tray. The optical fiber distribution mechanism is disposed between the tray and the top cover plate, and includes a slide rail mounted on the tray and a sliding mechanism mounted on the top cover plate. The distribution plate on the slide rail is provided with two slide rails and is installed between the two slide rails. The distribution plate includes a support base that runs on the slide rail and a base plate fixed to the upper end face of the support base. Multiple cable trays are provided through the support base. A rotating shaft is installed on the base plate and the base plate is connected to a shaft plate through the rotating shaft. The wire of the MPO connector is wound on the shaft plate. An MPO connector plug is fixed on the support base on one side of the base plate. MPO connector terminals are provided at both ends of the MPO connector plug. The two MPO connector terminals are respectively connected to the two ends of the MPO connector wire.

[0006] Preferably, the rear panel includes a plate body, with sliding grooves extending through both ends of the plate body. An operating block that contacts and connects with the plate body is provided in each of the two sliding grooves. An inner slider is fixed on each of the two operating blocks, and a locking block and a corner block are fixed at both ends of the inner slider, respectively.

[0007] Preferably, two locking holes are provided through the top cover plate, and the locking blocks on the two inner sliders pass through the two locking holes respectively and are in contact with the inner walls of the two locking holes.

[0008] Preferably, two viewing windows are fixed on the front panel, and both viewing windows extend through both ends of the front panel.

[0009] Preferably, a connecting end is fixed on the tray, and L-shaped ear plates are fixed at both ends of the tray. Screw holes are provided on both ear plates. The enclosure can be fixed to the cabinet by passing screws through the screw holes and screwing them into the corresponding screw holes on the cabinet.

[0010] Preferably, each end of the tray has a contact patch, and both ends of the tray and the two patches have positioning holes. Each patch has a cable management sleeve. By passing two screws through the two patches and inserting them into the two positioning holes, the two patches can be fixed to the tray.

[0011] Preferably, there are two sets of fiber optic distribution mechanisms, and the two sets of fiber optic distribution mechanisms are symmetrically distributed on the tray.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a novel ODF chassis structure, which includes a chassis and an optical fiber distribution mechanism mounted on the chassis.

Each set of fiber optic distribution mechanisms 2 has two slide rails 21, and the distribution plate 22 is installed between the two slide rails 21.

[0031] Please see Figure 3 The rear panel 13 includes a plate 131. Slide grooves 132 are provided through both ends of the plate 131. An operation block 133 is provided in each of the two slide grooves 132 and is in contact with the plate 131. An inner slider 134 is fixed on each of the two operation blocks 133. A locking block 135 and a corner block 136 are fixed at both ends of the inner slider 134, respectively.

[0032] Please see Figure 4 Two locking holes are provided through the top cover plate 12.

Then continue to slide the distribution tray 22 outwards until... Figure 7 The state shown in the image.

[0035] Please see Figure 7Since the wires of the MPO connector are all wound on the distribution tray 22, and the MPO connector terminals 226 at both ends of the MPO connector are fixed to multiple cable trays 227 by cable ties, the cable ties can be cut by using external tools such as scissors, and the two MPO connector terminals 226 can be inserted into the two MPO connector plugs 225 respectively to complete the assembly of the MPO connector. Then, the distribution tray 22 can be pushed into the cavity of the housing 1, and the assembly can be completed without removing the distribution tray 22. The installation of the MPO connector in this solution is more convenient, time-saving, labor-saving and easy to use than the existing technology.
