The outer diameter of the fixed block 222 is larger than the outer diameter of the insert block 221; the connecting portion 21 is provided with a card slot 211 for the fixed block 222 to be plugged in.

[0038] Reference Figure 4 and Figure 5In this embodiment, a slide plate 23 is slidably mounted within the engaging groove 211. A spring 26 is disposed between the slide plate 23 and the inner wall of the engaging groove 211. The elastic force of the spring 26 is used to drive the engaging block toward one side of the engaging groove 211. Two blocking members 24 are rotatably mounted on the slide plate 23. The spacing between the two blocking members 24 matches the inner diameter of the engaging groove 211. The blocking members 24 include a rotating piece 241 rotatably mounted on the slide plate 23 and a blocking block 242 mounted on the side of the rotating piece 241 away from the slide plate 23. A torsion spring (not shown) is disposed at the hinged connection between the rotating piece 241 and the slide plate 23. The elastic force of the torsion spring is used to drive the blocking pieces of the two blocking members 24 to rotate away from each other.

[0039] An unlocking rod 25 is rotatably installed in the snap-fitting slot 211, and the slide plate 23 is provided with a first positioning slot 231 and a second positioning slot 232 for the unlocking rod 25 to be inserted into; when the unlocking rod 25 is inserted into the first positioning slot 231, the hinge between the slide plate 23 and the blocking member 24 is located in the snap-fitting slot 211; when the unlocking rod 25 is inserted into the second positioning slot 232, the hinge between the slide plate 23 and the blocking member 24 is located outside the snap-fitting slot 211.

[0040] Reference Figure 4 The two ends of the first positioning groove 231 and the second positioning groove 232 are respectively connected by the first unlocking groove 233 and the second unlocking groove 234. The first unlocking groove 233 is used to guide the unlocking rod 25 to transfer from the second positioning groove 232 to the first positioning groove 231, and the second unlocking groove 234 is used to guide the unlocking rod 25 to transfer from the first positioning groove 231 to the second positioning groove 232.

[0041] Reference Figure 5 When the fixing block 222 needs to be inserted into the clamping groove 211, the fixing block 222 is inserted between the two rotating pieces 241 and abutted against the slide plate 23, and the slide plate 23 is pushed toward one side of the clamping groove 211; at this time, the unlocking rod 25 enters the first unlocking groove 233 from the second positioning groove 232, and guides the unlocking rod 25 into the first positioning groove 231 under the guidance of the second unlocking groove; at the same time, the hinge of the rotating plate and the slide plate 23 enters the clamping groove 211, and the rotating plate rotates along its own hinge, so that the two blocking blocks 242 abut against the insertion block 221; and when the unlocking rod 25 enters the first positioning groove 231, the elastic force of the spring 26 can drive the unlocking rod 25 to be inserted into the first positioning groove 231 under normal conditions, thereby fixing the plug-in component 22.

[0042] When unlocking is required, the user will press the unlocking rod 25 to move it out of the first positioning groove 231 and move it to the position of the second positioning groove 232 through the second unlocking groove 234, and the elastic force of the spring 26 can keep the unlocking rod 25 normally inserted in the second positioning groove 232; at this time, the hinge between the slide plate 23 and the blocking member 24 is located outside the clamping groove 211, and the elastic force of the torsion spring is used to force the free ends of the two blocking members 24 to rotate toward the side away from each other, so that the plug block 221 can be smoothly pulled out of the clamping groove 211, thereby realizing the separation of the plug-in assembly 22.

[0043] Reference Figure 1 and Figure 6 The unit module 1 includes an inner tray body 11 for installing optical fibers, a front mounting shell 13 sleeved on the front end of the inner tray body 11, and a rear mounting shell 14 sleeved on the rear end of the inner tray body 11. The front mounting shell 13 and the rear mounting shell 14 together form an outer shell 12; an insert block 221 is arranged on the front mounting shell 13, and the rear mounting shell 14 is provided with a slider 141. The extension direction of the slider 141 is in the same direction as the extension direction of the rear mounting shell 14. The connecting block is provided with a slide groove 2827 for the rear slider 141 to be inserted. The cooperation between the slider 141 and the slide groove 2827 can increase the contact area between the connecting block and the outer shell 12, thereby improving the stability of the connection of all unit modules 1.

[0044] Reference Figure 6 A guide block 142 is provided on the side of the slider 141 away from the front mounting housing 13. The outer diameter of the guide block 142 on the side away from the slider 141 is smaller than the outer diameter of the guide block 142 on the side close to the slider 141. The provision of the guide block 142 facilitates guiding the slider 141 into the slide groove 2827, further improving the installation efficiency of the connecting portion 21 and the outer shell 12.

[0045] Reference Figure 1 The inner tray body 11 is provided with a plurality of elastic card blocks 15, and the front mounting shell 13 and the rear mounting shell 14 are both provided with elastic card slots 16 for the elastic card blocks 15 to be inserted; the elastic card blocks 15 have a simple structure and can improve the convenience of installation of the outer shell 12 and the inner tray body 11.

[0046] A cable management area 17 is provided in the middle of the inner tray body 11. This area is provided with a baffle 18, and the cables are clamped between the baffle 18 and the inner wall of the cable management area 17. Clamping the cables between the baffle 18 and the cable management area 17 increases the stability of the cables within the inner tray body 11 and reduces the possibility of the cables hooking onto the outer shell 12 when the outer shell 12 is disconnected from the inner tray body 11, thereby improving the convenience of withdrawing the outer shell 12.

[0047] An LC adapter 3 is provided at the front end of the inner tray body 1111. In this embodiment, the LC adapter 3 is an LC six-link adapter, so that the template unit has 12-core optical fibers. The 12*12*1 layout is adopted in the 1U height distribution rack, so that the capacity of the module box reaches 144 cores, which can facilitate on-site construction while meeting high-density capacity requirements.

[0048] An MPO adapter 4 is provided at the rear end of the inner tray body 11. The MPO adapter 4 can simultaneously connect the optical fibers connected to the LC adapter 3 to improve the efficiency of optical fiber network wiring and data transmission capabilities; and the front mounting shell 13 and the rear mounting shell 14 can wrap the LC adapter 3 and the MPO adapter 4 to improve the aesthetics of the unit module 1.

[0049] In this embodiment, the rear end of the inner tray body 11 defines a mounting hole 43 for connecting to the cable management system. A mounting block 41 is inserted into the mounting hole 43, and the MPO adapter 4 is mounted on the mounting block 41. Anti-slip blocks 42 are provided on opposite sides of the mounting block 41, and the mounting hole 43 defines an anti-slip groove 44 for receiving the anti-slip blocks 42. The insertion and engagement of the mounting blocks 41 with the mounting hole 43 allows the MPO adapter 4 to be removed and replaced, thereby extending the service life of the unit module 1.

[0050] The implementation principle of a push-to-unlock high-density MPO module box in the embodiment of the present application is as follows:

[0051] By arranging multiple unit modules 1 side by side, high-density integration of optical fiber connections can be achieved, and the number of unit modules 1 can be flexibly increased or decreased according to actual user needs; and by arranging the unit modules 1 in the inner tray body 11 and the outer shell 12, the optical fiber cables can be hidden inside the outer shell 12, and the cables between two adjacent unit modules 1 can be separated, making it easy to inspect and repair each unit module 1.

[0052] When it is necessary to connect two adjacent unit modules 11, the guide surfaces 27 of the two stop blocks 242 abut against the fixed block 222, so that the two stop blocks 242 move toward the side away from each other under the guidance of the guide surfaces 27, so that the fixed block 222 can be smoothly inserted into the snap-in groove 214, thereby completing the connection between the connecting part 21 and the outer shell 12.

[0053] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
