Description

Technical Field

[0001] This utility model belongs to the technical field of communication equipment boxes, and specifically relates to an optical fiber communication equipment box. Background Technology

[0002] With the rapid development of internet technology and the increasingly widespread application of big data, data center server rooms require a large number of fiber optic distribution boxes. Fiber optic communication boxes provide installation space for fiber optic distribution frames, which are used for fixing and protecting optical cables, and are an indispensable part of data center server rooms.

[0003] Existing technologies disclose fiber optic distribution frames, such as CN118465944B, which discloses a fiber optic distribution frame including a housing with sliding grooves on both the left and right sides of its inner cavity; a fiber optic distribution tray with its left and right ends slidably nested within the sliding grooves; mounting cavities on the front of both sides of the fiber optic distribution tray, with locking mechanisms nested inside the mounting cavities; a fastening mechanism installed on the front side of the fiber optic distribution tray; and a pop-out mechanism on the rear side of the distribution tray. The fastening mechanism installed on the front side of the fiber optic distribution tray disclosed in this patent provides support and fixation for the fiber optic connectors, improving the stability of the connection between the fiber optic connectors and the line interface, and effectively preventing misalignment between the fiber optic connectors and the line interface.

[0004] While the publicly disclosed fiber optic distribution frame undeniably achieves the aforementioned effects, it also has certain shortcomings: In practical use, both ends of the line interface require fiber optic connectors for line connectivity. However, in this patent, the rear wall of the housing needs to provide support for the spring plate. This causes the spring plate and housing to interfere with the fiber optic line located inside the line interface. Furthermore, the housing lacks through holes for external fiber optic cables to enter the fiber optic distribution tray and connect to the inner end of the line interface, making it difficult to meet actual needs. Additionally, the locking mechanism of this patent requires the coordinated operation of multiple components, including a limiting rod, tilting plate, spring, U-shaped component, arc-shaped pressing block, and opening, to install the fiber optic distribution tray into or out of the housing. The numerous and tightly linked components result in a relatively complex structure, cumbersome assembly, and difficulties in subsequent maintenance and repair.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0039] The technical solution of this utility model patent will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0040] Example

[0041] See appendix Figure 1-10 A fiber optic communication equipment box, comprising:

[0042] The enclosure 100 has doors 101 on its front and rear sides for opening and closing. A transparent glass panel (as shown in the attached diagram) is installed in the middle of each door 101. A wire hole 102 is provided on the front and rear sides of the top of the enclosure 100.

[0043] Mounting bracket 200 fixed inside housing 100;

[0044] Multiple support frames 300 are installed at intervals on the mounting frame 200. Specifically, each of the two ends of the support frame 300 has an integrally formed mounting ear 301, and the mounting ear 301 has a mounting hole 302. The mounting frame 200 has a through hole 201 corresponding to the mounting hole 302. The support frame 300 can be fixed on the mounting frame 200 by bolting through the through hole 201 and the mounting hole 302 and then threading a nut.

[0045] Disassemble and install multiple wiring boxes 400 that are installed inside the support frame 300 and distributed along the length of the support frame 300; each wiring box 400 includes a box body 401 whose lower end is snapped into the support frame 300 and has a wire hole 4013 at the rear end, multiple line interfaces 402 fixed to the front end of the box body 401, a limiting strip 403 (extending along the length of the box body 401) fixed inside the box body 401 and corresponding to the line interfaces 402, a box cover 404 covering the side opening of the box body 401, and a restraint fixed to one side of the front end of the box body 401. The frame 405 has multiple rows of line interfaces 402 spaced vertically along the height of the box 401, with two interfaces spaced in each row. The limiting strip 403 has guide grooves 4031 with an L-shaped cross-section, and the top of the vertical section of the guide groove 4031 extends through the top of the limiting strip 403. A gap is left between the front end of the limiting strip 403 and the inner end of the line interface 402. It is easy to understand that the limiting strip 403 has two guide grooves 4031 spaced apart, so each guide groove 4031 corresponds to one line interface 402.

[0046] In this embodiment, the support frame 300 is U-shaped. Multiple partition plates 303 are fixed at intervals on the bottom wall of the support frame 300. Two adjacent partition plates 303 form a receiving groove 304 for accommodating the bottom of the wiring box 400. A limiting plate 305 is fixed at the front end and the rear end of the receiving groove 304. A locking block 306 with a semi-circular cross-section is fixed at the top of the limiting plate 305 near the box body 401. The front end and the rear end of the box body 401 are provided with slots 406 corresponding to the locking block 306 near the bottom. When the lower end of the wiring box 400 is pressed down to abut the bottom wall of the receiving groove 304, the locking block 306 enters the slot 406.

[0047] In this embodiment, a sliding groove 4011 is fixed at the top and bottom of the side opening of the box body 401, and a protrusion 4012 (with a chamfered edge) is integrally formed at the front end of the sliding groove 4011; a sliding strip 4041 that slides and guides the sliding groove 4011 is fixed at the top and bottom of the inner side of the box cover 404, and a groove 4042 corresponding to the protrusion 4012 is opened at the front end of the sliding strip 4041; when the sliding strip 4041 of the box cover 404 slides along the sliding groove 4011 of the box body 401 to the front end of the box cover 404, the protrusion 4012 enters the groove 4042. In addition, a switch groove 4043 is formed by an inward recess in the middle of the box cover 404.

[0048] In use, the support frame 300 can be fixed to the mounting frame 200 by threading a bolt through the through hole 201 and the mounting hole 302 and then connecting a nut. To open the cover 404, use your fingers to push the cover 404 backward with the switch groove 4043. The protrusion 4012 and the groove 4042 will separate. Continue to push the cover 404 backward until the slider 4041 and the slide groove 4011 separate, then the cover 404 can be removed. The optical cable passes through the lead hole 102 on the rear top of the housing 100 and enters the housing 100. Then, it enters the housing 401 through the wire hole 4013 on the cover 404. After connecting the optical fiber connector inside the optical cable, insert it into the inner end of the line interface 402, and transfer the section of the optical fiber corresponding to the limiting strip 403 to the corresponding position in the guide groove 4031 of the limiting strip 403. In this way, the guide groove 4031 can support the optical fiber, preventing the optical fiber from sagging due to its own weight, which could cause line faults at the optical fiber connector and line interface 402. At the same time, the guide groove 4031 can also bind and organize the optical fiber, making the distribution of the optical fiber in the box 401 more orderly, which is convenient for subsequent troubleshooting and maintenance.

[0049] After the fiber optic connector at the inner end of the line interface 402 is installed, the slide bar 4041 is placed in the slide groove 4011, and the cover 404 is pushed forward until the protrusion 4012 enters the groove 4042. The protrusion 4012 and the groove 4042 cooperate with each other to limit the cover 404.

[0050] Then, the lower end of the junction box 400 is placed in the receiving groove 304 and pressed down. During the pressing process, the front and rear ends of the box body 401 exert an outward pushing force on the locking block 306, and the limiting plate 305 deforms outward. When the lower end of the box body 401 abuts against the bottom wall of the receiving groove 304, the locking block 306 enters the locking groove 406, and the limiting plate 305 returns to its initial position. In this way, through the cooperation of the locking block 306 and the locking groove 406, the lower end of the junction box 400 is locked into the receiving groove 304 at the corresponding position, and it is convenient to remove the junction box 400 from the receiving groove 304 for maintenance later.

[0051] Next, insert the external fiber optic connector into the outer end of the line interface 402. After the fiber optic connector at the outer end of the line interface 402 is installed, organize the fiber optic cables and use cable ties or Velcro to secure them to the binding bracket 405 on the front side of the housing 401. By setting the binding bracket 405, the fiber optic cables at the outer end of the line interface 402 can be organized and bound in an orderly manner, which facilitates subsequent troubleshooting and maintenance and meets practical needs.

[0052] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
