Description

Technical Field

[0001] The utility model relates to the technical field of telecommunication equipment, in particular to an optical fiber ODF frame structure and a distribution frame cabinet. Background Art

[0002] ODF rack, or ODF fiber distribution frame, is the main equipment in current communication wiring equipment and is mainly used for optical cable termination. The optical cable enters the base station through the wiring rack. The main function of ODF is to complete the termination. Each optical fiber in the optical cable corresponds to each other, which is convenient for using the optical port. As we all know, there is only one optical path, so ODF is equivalent to a row of optical path outlets, which are then connected using jumpers to connect the equipment and the optical cable to complete the local transmission. The fiber distribution frame consists of a rack, a sub-rack, a tray, a fusion box, accessories to protect the fusion point, a fiber optic adapter, and a pigtail. The rack should have a place to store terminal optical cables and excess pigtails, and a place to place optical attenuators.

[0003] In the current fiber optic distribution frame architecture, the fusion fiber optic box is fastened to the main frame through a snap device made of engineering plastic. When a new fiber optic line needs to be fused, the operator must frequently unfasten and pull the snap to take out the fusion fiber optic box for connection. However, this repeated operation process can easily cause the plastic snap to break due to fatigue over a long period of time, which in turn causes the fusion fiber optic box to be unable to be effectively fixed to the frame, seriously affecting its normal functional use and reducing the overall protection efficiency after the fiber optic connection is completed. Utility Model Content

[0004] The utility model aims to provide an optical fiber ODF frame structure and a distribution frame cabinet to solve the problem proposed in the above background technology that the fiber splicing box on the existing optical fiber ODF frame structure is connected to the frame body by a plastic clip. When it is necessary to splice the fibers to connect a new optical fiber line, the clip needs to be opened repeatedly to pull out the splicing box for connection. Over time, the plastic clip will break, resulting in the inability to fix the splicing box, affecting the normal use of the splicing box and reducing the protection capability of the optical fiber after connection.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an optical fiber ODF frame structure, comprising: an optical fiber distribution frame, the inner wall of which is provided with a drawer bar, and the outer wall of which is provided with a slot; a fixing bar, which is placed inside one side of the optical fiber distribution frame, the outer wall of which is rotatably connected with a knob, and the outer wall of the knob is sleeved on the outer wall of the optical fiber distribution frame, the outer wall of the knob is provided with a stop bar, and a positioning groove, which is provided on the outer wall of the optical fiber distribution frame and is located at the corner of the optical fiber distribution frame next to the knob;

[0006] A fiber splicing box is inserted into a drawer bar of a fiber distribution frame. A card slot is provided on one side of the front end of the fiber splicing box, and the card slot is located in the positioning slot and is supported by a rotating blocking bar. An insert block is provided on the other side of the front end of the fiber splicing box, and the insert block is inserted into the slot.

[0007] By adopting the above technical solution, after the fiber splicing box is inserted into the optical fiber distribution frame, the card slot on one side of the fiber splicing box is positioned in the positioning slot. At this time, the knob is rotated ninety degrees to rotate the blocking bar into the card slot to limit the fiber splicing box, and then the plug-in block on the other side is inserted into the slot, so as to achieve the effect of inserting and locking the fiber splicing box on the optical fiber distribution frame, avoiding the problem that the plastic buckle breaks and cannot be used when the fiber splicing box is removed by snap-in method, ensuring the normal locking use of the fiber splicing box, and improving the protection capability of the optical fiber after connection.

[0008] Preferably, the width of the slot is the same as the width of the blocking bar, and the corners on one side of the slot on the fiber splicing box can overlap in the positioning groove.

[0009] By adopting the above technical solution, by overlapping the card slot and positioning it in the positioning groove, it can be ensured that the position of the card slot after insertion matches the position of the rotated baffle, ensuring that the baffle can prevent the card slot from moving outward, thereby achieving the effect of locking the fiber splicing box.

[0010] Preferably, multiple groups of knobs, stop bars and slots are evenly arranged on both sides of the optical fiber distribution frame, and their positions correspond one-to-one to the drawer bars at different positions.

[0011] By adopting the above technical solution, by installing multiple sets of knobs, baffles and slots, multiple sets of fiber splicing boxes can be installed simultaneously on one side of the corresponding position of the drawer bar to meet the needs of a large number of optical fiber connections and increase the number of optical fibers arranged in a single device, so as to facilitate unified management of optical fibers in the area.

[0012] Preferably, the plug-in block and the slot are rectangular in overall shape, and the plug-in block and the slot fit each other after being plugged in.

[0013] By adopting the above technical solution, by fitting the same rectangular plug-in block and the slot together, when the fiber splicing box is pulled by external force, one end is blocked and locked by the blocking bar, and the force on the other end will cause one end of the plug-in block to press against the inner wall of the slot, thereby preventing the plug-in block from being pulled out of the slot.

[0014] Preferably, an upper magnet is inlaid at the bottom of the baffle, and a lower magnet is inlaid at the bottom of the slot, and the position of the upper magnet is attracted correspondingly to the position of the lower magnet.

[0015] By adopting the above technical solution, by embedding the upper magnet and the lower magnet at their respective bottoms, after the baffle is rotated to the slot, the upper magnet will be attracted to the lower magnet, giving it a certain attraction, thereby limiting the random movement of the knob and the baffle after being blocked, and improving the stability of the knob and the baffle after being blocked.

[0019] By adopting the above technical solution, the position of the hanging column can be moved arbitrarily on the strip hole. After moving the position, the nut can be tightened on the threaded groove so that the nut will be pressed against one side of the strip hole, and the hanging column will be firmly pressed against the partition plate. Therefore, the position can be adjusted arbitrarily according to the optical fiber hanging needs, thereby meeting different hanging needs and improving the regularity of optical fiber arrangement in the cabinet body.

[0020] Preferably, a disc is provided at one end of the wire hanging column, and the diameter of the disc is greater than the width of the strip hole. The nut is tightened to cooperate with the disc to press the wire hanging column onto the strip hole.

[0021] By adopting the above technical solution, by placing the disc at one end of the hanging pole, the disc can be made to abut against one side of the wire partition plate, and the nut is tightened on the other side to abut the hanging pole against the wire partition plate, so that the position of the hanging pole can be adjusted by the tightness of the nut, making it simple and quick to adjust the arrangement of the optical fiber.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] (1) After the fiber splicing box is inserted into the optical fiber distribution frame, the card slot on one side of the fiber splicing box is positioned in the positioning slot. At this time, the knob is rotated 90 degrees to rotate the stopper into the card slot to limit the fiber splicing box, and then the plug-in block on the other side is inserted into the slot, so as to achieve the effect of inserting the fiber splicing box into the optical fiber distribution frame, avoiding the problem that the plastic buckle is easily broken and cannot be used when the fiber splicing box is removed by the card connection method, ensuring the normal locking and use of the fiber splicing box, and improving the protection capability of the optical fiber after connection;

[0024] (2) By embedding an upper magnet and a lower magnet at the bottom of the stop bar and the card slot respectively, after the stop bar is rotated to the card slot, the upper magnet will be attracted to the lower magnet, making it have a certain attraction, thereby limiting the free movement of the knob and the stop bar after being blocked, and improving the stability of the knob and the stop bar after being blocked;

[0025] (3) The position of the hanging column can be moved freely on the strip hole. After the position is moved, the nut can be tightened on the thread groove, so that the nut will be pressed against one side of the strip hole, and the hanging column will be firmly pressed against the partition plate. Therefore, the position can be adjusted freely according to the demand for hanging optical fiber cables, thereby meeting different hanging requirements and improving the regularity of optical fiber arrangement in the cabinet body.
