Abstract
Description
Technical Field
[0001] This application relates to the field of optical fiber communication technology, and particularly to a high-density MPO box. Background Art
[0002] The MPO module box is commonly used for optical fiber backbone connection and wiring management in the MDA (Main Distribution Area), IDC (Internet Data Center) or EDA (Equipment Distribution Area). The MPO module box can be installed in a rack-mounted or wall-mounted chassis to achieve capacity expansion, and is an important part of the optical fiber communication grid cabling system.
[0003] Currently, the MPO module boxes on the market mainly install 12-core or 24-core unit modules in a 1U-high patch panel in three layers. In order to achieve a capacity of 144 cores in a 1U height, a 12x4x3 layer or 24x2x3 layer pull-out structure is basically adopted. Such a pull-out structure may cause the cable management to be unsmooth and inconvenient when in use and maintenance, especially when performing pull-out operations on the second and third layers. For the existing fixed MPO module boxes, although there is no pull-out action during use and maintenance, with a 24x3x1 layout, only a capacity of 96 cores can be achieved.
[0004] In summary, there is a need for an MPO module box that is easy to use and maintain while having a high capacity. Summary of the Utility Model

[0035] The following further elaborates on the present application Figures 1 - 3 in conjunction with the accompanying drawings.
[0036] An embodiment of the present application discloses a high-density MPO module box. Referring to Figure 1 and Figure 2 , a high-density MPO module box includes an outer housing 1, an inner tray body 2, an MPO adapter 3, two LC six-way adapters 4, and a protective part 5; the inner tray body 2 is installed in the inner cavity of the outer housing 1, and the inner tray body 2 is detachably connected to the outer housing 1.
[0037] The MPO adapter 3 is installed at one end of the inner tray body 2. The inner tray body 2 has a connecting part 21 at the end far from the MPO adapter 3, and two connecting cavities 22 are formed in the connecting part 21, and the two LC six-way adapters 4 are respectively installed in the two installation cavities 51. The two LC six-way adapters 4 are arranged at intervals along the width direction of the outer housing 1, and the six interfaces of each LC six-way adapter 4 extend along the height direction of the outer housing 1. Connecting slide rails 11 are arranged on both the left and right sides of the outer housing 1, and the connecting slide rails 11 extend along the length direction of the outer housing 1, and the connecting slide rails 11 are used for sliding connection with the patch panel.
[0038] The protective part 5 has two installation cavities 51, and the two installation cavities 51 are respectively used for inserting the two LC six-way adapters 4. Thus, the LC six-way adapters 4 are wrapped by the protective part 5 to avoid exposure.
[0039] Referring to Figure 3 , when installing the MPO module box, the outer housing 1 is inserted into the patch panel through the connecting slide rails 11. Within the height of 1U, 12 such module boxes can be installed to form a 12x12x1 layout, and the capacity reaches 144 cores within the height of 1U. In addition, since only one layer of module boxes is arranged within the height of 1U, and the module boxes are slidably connected to the patch panel through the sliding rails, it is also convenient for use and maintenance. Therefore, the MPO module box not only has a high capacity but also is convenient for use and maintenance.
[0040] Specifically, in this embodiment, the connecting slide rails 11 connected to the left and right sides of the outer housing 1 are arranged staggeredly, that is, an asymmetric structural design is adopted, saving the installation space of multiple module boxes.
[0041] The connecting slide rail 11 has a first insertion end and a second insertion end, and the first insertion end and the second insertion end are symmetrically arranged. The axis of symmetry of the first insertion end and the second insertion end is perpendicular to the central axis of the connecting slide rail 11. With this design, the connecting slide rail can be inserted into the patch panel from the front of the patch panel or from the back, improving the installation flexibility of the module box and the convenience of cable management and layout.
[0042] The LC six-way adapter 4 is provided with an adapter flange (not shown in the figure). Since the flanges of MPO adapters 3 on the market have different thicknesses (the commonly used thicknesses are 3 mm and 4 mm), an adapter flange detachably connected to the LC six-way adapter 4 is provided. When the thickness of the MPO adapter 3 is 4 mm, the adapter flange is connected to the LC six-way adapter 4. If the thickness of the MPO adapter 3 is 3 mm, the LC six-way adapter 4 without the connected adapter flange is used.
[0043] It can be understood that in other embodiments, two types of LC six-way adapters 4 can also be produced or purchased, one connected with an adapter flange and the other without an adapter flange.
[0044] A limiting member 23 is provided in the inner tray lift. The limiting member 23 is provided with a cable management groove 24 for allowing wires to pass through, so as to facilitate the arrangement of wires.
[0045] In this embodiment, the cable management groove 24 is arranged in a wavy shape. On the one hand, it limits the wires to facilitate cable laying; on the other hand, it extends the length of the cable management groove 24 to further improve the neatness of cable laying.
[0046] In other embodiments, the cable management groove 24 can also be in other shapes such as a "Z" shape.
[0047] In this embodiment, there is one cable management groove 24. In other embodiments, there can also be multiple cable management grooves 24.
[0048] Among them, the limiting member 23 and the inner tray body 2 can be integrally formed, or can be fixed by bonding or welding. The formation of the cable management groove 24 can be formed by opening in a whole limiting member 23, or can be formed by limiting with two structural blocks.
[0049] The inner tray body 2 is detachably connected to the outer shell body 1. The specific structure of their detachable connection is as follows: on both the left and right sides of the connection part 21, first clamping parts 25 are integrally formed. On both the left and right sides of the outer shell body 1, first clamping grooves 12 are penetrated and opened. The first clamping grooves 12 are used for the first clamping parts 25 to be clamped. When assembling the inner tray body 2 and the outer shell body 1, insert the inner tray body 2 into the inner cavity of the outer shell body 1 along the length direction of the outer shell body 1. Finally, make the first clamping parts 25 snap into the first clamping grooves 12, realizing the detachable connection between the inner tray body 2 and the outer shell body 1, which is convenient for the arrangement and maintenance of the module box.
[0050] In this embodiment, two first clamping grooves 12 are provided on each side of the outer shell body 1, and two first clamping parts 25 are correspondingly provided on each side of the connection part 21 to ensure the connection stability between the inner tray body 2 and the outer shell body 1.
[0051] The protection part 5 is detachably connected to the inner tray body 2. The specific structure of their detachable connection is as follows: on both the left and right sides of the connection part 21, second clamping parts 26 are integrally formed. On both the left and right sides of the protection part 5, second clamping grooves 52 are penetrated and opened. The second clamping grooves 52 are used for the second clamping parts 26 to be clamped. When assembling the protection part 5 and the inner tray body 2, move the protection part 5 towards the direction close to the inner tray body 2, so that the two LC six - way adapters 4 are respectively inserted into the two installation cavities 51. Then continue to move the protection part 5, so that the second clamping parts 26 snap into the second clamping grooves 52.
[0052] In this embodiment, two second clamping grooves 52 are provided on each side of the protection part, and two second clamping parts 26 are correspondingly provided on each side of the connection part 21 to ensure the connection stability between the protection part 5 and the inner tray body 2.
[0053] Furthermore, on the side of the protection part 5 away from the inner tray body 2, a gripping part 53 is integrally formed. The gripping part 53 extends along the length direction of the outer shell body 1, which is convenient for the staff to apply force when pulling out the module box.
[0054] The implementation principle of a high - density MPO module box in this application embodiment is as follows: when assembling the module box, first connect the two LC six - way adapters 4 to the connection part 21 of the inner tray body 2, and at the same time install the MPO adapter 3 at the other end of the inner tray body 2; then insert the inner tray body 2 into the inner cavity of the outer shell body 1, and use the cooperation of the first clamping part 25 and the first clamping groove 12 to realize the stable connection between the inner tray body 2 and the outer shell body 1; then move the protection part 5 along the length direction of the inner tray body 2, and use the cooperation of the second clamping part 26 and the second clamping groove 52 to realize the stable connection between the protection part 5 and the inner tray body 2.
[0055] When installing the module box, arrange the module boxes within the 1U height according to the layout of 12x12x1, so as to have a capacity of 11 cores within the 1U height and facilitate maintenance and use.
[0056] The above are all preferred embodiments of the present application. Without limiting the protection scope of the present application accordingly, therefore: Any equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
