Description

Technical Field

[0002] An optical fiber distribution chassis is used for the wiring connection between an optical cable and an optical communication device. An optical signal is led out through an optical fiber distribution box in the distribution box to realize the optical wiring function. At the same time, it is also applicable to the protective connection of an optical cable and a distribution pigtail. Its main application sites are corridors or indoors.

[0003] In the prior art, generally only 3 layers of draw-out plates can be placed in the space of a 1U distribution chassis. A plurality of guide rails and buckle unlocking devices are arranged at intervals on each draw-out plate to cooperate with the side part of the optical fiber module for connection. When unlocking the optical fiber module, the draw-out plate needs to be pulled to the unlocking position of the chassis, and the buckle unlocking device is pulled to unlock, and then the optical fiber module is extracted and pulled out along the guide rail. The operation is relatively troublesome. And because the guide rails and the buckle unlocking devices will occupy a certain lateral space in the chassis, the accommodation space of the optical fiber module is reduced. Finally, only 4 optical fiber modules can be arranged on each draw-out plate in the 1U chassis space, and only 12 optical fiber modules can be arranged in total. And each optical fiber module generally supports 12-core connection, and the core number limit is 144F, which is difficult to meet the higher-density connection requirements.

[0037] Refer to Figure 1 、 Figure 2 、 Figure 5 and Figure 6 , according to the high-density pull-out optical fiber distribution device of the first aspect embodiment of the present utility model, it includes a chassis main body 100, a carrier 200, an optical fiber module 300 and a plugging structure 400. The chassis main body 100 has a receiving groove 110 extending in the front-back direction, and the front end of the receiving groove 110 has an opening. The carrier 200 is slidably arranged in the receiving groove 110 along the front-back direction. The plugging structure 400 is arranged at the rear parts of the carrier 200 and the optical fiber module 300, and the optical fiber module 300 is plugged on the carrier 200 through the plugging structure 400. By arranging the corresponding plugging structure 400 at the rear part of the optical fiber module 300, the optical fiber module 300 can be plugged with the plugging structure 400 on the carrier 200 by using the rear part, so that the side space of the optical fiber module 300 will not be occupied, and thus the sides of the optical fiber modules 300 can be closely arranged adjacent to each other, so that more optical fiber modules 300 can be placed on the carrier 200 within the 1U chassis space, and further the connection density of the connection core wires within the 1U chassis can be improved.

[0038] Specifically, the carrier 200 can be a plate-like structure, and the carrier 200 can be slidably connected to the front and rear of the chassis main body 100 horizontally. The specific sliding structure is not described in detail here. The optical fiber module 300 is installed on the carrier 200. During normal operation, the carrier 200 is within the receiving groove 110. When the optical fiber module 300 needs to be disassembled and assembled, the carrier 200 can be pulled forward to facilitate the disassembly and assembly of the optical fiber module 300. When the optical fiber module 300 is disassembled and assembled, the optical fiber module 300 can be inserted into the carrier 200 from front to back. The insertion structure 400 at the rear of the optical fiber module 300 can be inserted and locked with the insertion structure 400 on the carrier 200. The specific insertion structure 400 is not limited here. The carrier 200 can support the optical fiber module 300. It can be understood that the insertion structure 400 can be self-unlocked, that is, the user can pull out the optical fiber module 300 with a certain force, and the user does not need to operate the unlocking component, and the operation is simple, which can facilitate the user to disassemble and assemble the optical fiber module 300. Since the insertion structure 400 is located at the rear of the optical fiber module 300, sliding structures do not need to be provided on the left and right sides of the optical fiber module 300, and corresponding guide rails do not need to be provided on the carrier 200 either. Furthermore, the available lateral space on the carrier 200 can be expanded. When multiple optical fiber modules 300 are installed, the sides of each optical fiber module 300 can be closely arranged side by side, the load capacity of the carrier 200 can be expanded, and thus the overall connection density can be increased.

[0039] Referring to Figure 5 and Figure 6 , in some embodiments of the present invention, at least three carriers 200 are provided and are spaced along the height direction of the chassis main body 100. Each carrier 200 can be inserted with at least five optical fiber modules 300, and each optical fiber module 300 can be closely arranged along the width direction of the carrier 200, so that the chassis main body 100 can be configured with at least fifteen optical fiber modules 300 and can support a connection density of at least sixty cores or at least one hundred and twenty cores or at least one hundred and eighty cores or at least four hundred and eighty cores or at least five hundred and forty cores or at least seven hundred and twenty cores or one thousand four hundred and forty cores. The core wire connection density within the 1U chassis space can be increased.

[0040] Specifically, the carrier 200 for accommodating the single-layer fiber optic module 300 remains unchanged in the longitudinal space. Three layers of carriers 200 can still be arranged in the accommodation groove 110. Each layer of the carrier 200 is provided with a corresponding plug-in structure 400. The rear part of each fiber optic module 300 is also provided with a plug-in structure 400 that cooperates with the carrier 200. Through the above plug-in structure 400, the carrier 200 that could originally accommodate only 4 fiber optic modules 300 can increase its load capacity to 5 fiber optic modules 300, and ultimately can be expanded to 15 fiber optic modules 300 within the space of a 1U chassis, improving the core wire connection density.

[0041] In some embodiments, if the fiber optic module is set to the 4MTP-4MTP type and has a conversion box with 32 cores (one MTP adapter has 8 cores), then 5 such 4MTP-4MTP conversion boxes can be arranged on a single carrier 200 of the chassis main body 100. A total of 15 4MTP-4MTP conversion boxes can be accommodated by the three layers of carriers 200, providing a total connection density of 480 cores.

[0042] In some embodiments, if the fiber optic module is set to the 4MTP-4MTP type and has a conversion box with 48 cores (one MTP adapter has 12 cores), then 5 such 4MTP-4MTP conversion boxes can be arranged on a single carrier 200 of the chassis main body 100.

[0043] In some embodiments, if the fiber optic module is set to the 4MTP-4MTP type and has a conversion box with 96 cores (one MTP adapter has 24 cores), then 5 such 4MTP-4MTP conversion boxes can be arranged on a single carrier 200 of the chassis main body 100. A total of 15 4MTP-4MTP conversion boxes can be accommodated by the three layers of carriers 200, providing a total connection density of 1440 cores.

[0044] In some embodiments, if the fiber optic module is set to the MTP-8LC type and has a fiber optic adapter panel with 8 cores, then 5 such MTP-8LC fiber optic adapter panels can be arranged on a single carrier 200 of the chassis main body 100. A total of 15 MTP-8LC fiber optic adapter panels can be accommodated by the three layers of carriers 200, providing a total connection density of 120 cores.

[0045] In some embodiments, if the fiber optic module is set to the MTP-8CS type and has a fiber optic distribution box with 8 cores, then 5 such MTP-8CS fiber optic distribution boxes can be arranged on a single carrier 200 of the chassis main body 100. A total of 15 MTP-8CS fiber optic distribution boxes can be accommodated by the three layers of carriers 200, providing a total connection density of 120 cores.

[0051] It can be understood that chassis of any size (including but not limited to 1-U, 2-U, and 4-U sizes) can include some or all of the foregoing characteristic structures and optical fiber modules disclosed herein. For example, when setting a 2-U sized chassis, it can accommodate a number of optical fiber modules that is 2 times or a connection density that is 2 times that of a 1-U chassis. The corresponding total core wire connection density can be 2 times that of a 1-U sized chassis. When setting a 4-U sized chassis, it can accommodate a number of optical fiber modules that is 4 times or a connection density that is 4 times that of a 1-U chassis. The corresponding core wire connection density can be 4 times that of a 1-U sized chassis.

[0052] Refer to Figure 2, in some embodiments of the present utility model, the plugging structure 400 includes an elastic limiting component 410 and a plugging slot component 420. The elastic limiting component 410 is arranged on the carrier 200, and the plugging slot component 420 is arranged on the optical fiber module 300. The plugging slot component 420 can be plugged and matched with the elastic limiting component 410, which is convenient for the disassembly and assembly of the optical fiber module 300.

[0053] Specifically, the elastic limiting components 410 can be closely arranged in 5 groups along the width direction of the carrier 200. The plugging slot components 420 corresponding to the elastic limiting components 410 are provided at the end of the optical fiber module 300 close to the chassis main body 100. The elastic limiting components 410 and the plugging slot components 420 can correspond one by one. During the actual installation process, the user can plug and match the optical fiber module 300 with the elastic limiting components 410 through the plugging slot components 420. The specific matching structure is not specifically limited herein. Through the above structure, the disassembly and assembly of the optical fiber module 300 can be realized more conveniently.

[0054] It should be noted that the plugging structure 400 is not limited to the above embodiments, and other embodiments can also be adopted. For example, a protruding elastic limiting part can also be provided at the end of the optical fiber module 300 close to the chassis main body 100, and a corresponding groove structure can be provided on the carrier 200. Through the plugging of the elastic limiting part and the groove structure, the rapid disassembly and assembly of the optical fiber module 300 and the carrier 200 can also be realized, and it is convenient for the optical fiber module 300 to be closely arranged on the side.

[0055] Refer to Figures 2 to 4 , in some embodiments of the present utility model, the elastic limiting component 410 includes a first elastic limiting member 411 and a second elastic limiting member 412. The first elastic limiting member 411 and the second elastic limiting member 412 are arranged opposite to each other. The plugging slot component 420 includes a first plugging slot 421 and a second plugging slot 422. The first plugging slot 421 and the second plugging slot 422 are respectively located on opposite sides of the optical fiber module. The first elastic limiting member 411 can be plugged and matched with the first plugging slot 421, and the second elastic limiting member 412 can be matched with the second plugging slot 422. Through the above structure, the connection stability of the optical fiber module 300 can be improved.

[0056] Specifically, the first elastic limiting member 411 and the second elastic limiting member 412 can both be made of elastic material or metal material. The first elastic limiting member 411 and the second elastic limiting member 412 are arranged at intervals. The optical fiber module 300 is provided with corresponding first insertion slots 421 and second insertion slots 422, which are respectively arranged near two side portions of the optical fiber module 300. During installation, the first insertion slot 421 and the second insertion slot 422 can be inserted into the first elastic limiting member 411 and the second elastic limiting member 412 at the same time. When the first insertion slot 421 is inserted into the first elastic limiting member 411, the first elastic limiting member 411 can deform and abut against the inner side wall of the first insertion slot 421 by elastic force to provide a certain locking force. When the second insertion slot 422 can be inserted into the second elastic limiting member 412, the second elastic limiting member 412 can deform and abut against the inner side wall of the second insertion slot 422 by elastic force to provide a certain locking force. The elastic forces of the first elastic limiting member 411 and the second elastic limiting member 412 can clamp or press the optical fiber module 300, thereby realizing locking. During disassembly, the user can apply a certain force to overcome the locking force generated by the first elastic limit and the second elastic limiting member 412, and then the optical fiber module 300 can be pulled out. Moreover, by performing insertion and connection at the ends near both sides of the optical fiber module 300, the connection stability of the optical fiber module 300 can be improved.

[0057] It can be understood that the elastic limiting assembly 410 can be a single elastic limiting member, and only a single insertion slot is correspondingly arranged on the optical fiber module 300. The single elastic limiting member and the single insertion slot can also realize insertion.

[0058] Referring to Figures 2 to 4 and Figure 8 and Figure 9 In some embodiments of the present invention, the first elastic limiting member 411 includes a first guide rail 4111 and a first elastic sheet 4112, and the second elastic limiting member 412 includes a second guide rail 4121 and a second elastic sheet 4122. The first guide rail 4111 and the second guide rail 4121 are both fixedly connected to the carrier 200. The first elastic sheet 4112 is connected to the first guide rail 4111, and the second elastic sheet 4122 is connected to the second guide rail 4121. The first insertion slot 421 can be slidably matched with the first guide rail 4111, and the second insertion slot 422 can be slidably matched with the second guide rail 4121. The first elastic sheet 4112 and the second elastic sheet 4122 are both arranged to gradually approach each other in the front-to-back direction. The first elastic sheet 4112 can abut against the side wall of the first insertion slot 421, and the second elastic sheet 4122 can abut against the side wall of the second insertion slot 422. Through the above matching structure, it is convenient to disassemble and assemble the optical fiber module 300, and the corresponding matching structure is simple and occupies a small space.

[0059] Specifically, one end of the first elastic piece 4112 can be fixedly connected to the first guide rail 4111 through a rivet, and the other end can elastically deform relative to the first guide rail 4111. Similarly, the second elastic piece 4122 is also connected to the second guide rail 4121 in this way. Moreover, both the first elastic piece 4112 and the second elastic piece 4122 are connected to the corresponding first guide rail 4111 and second guide rail 4121 at the front part, and the rear part can deform. And the first elastic piece 4112 and the second elastic piece 4122 are gradually approaching each other in the front-to-back direction. During installation, when the optical fiber module 300 is inserted from front to back, the first insertion slot 421 and the second insertion slot 422 can first abut against the first elastic piece 4112 and the second elastic piece 4122, and then press the first elastic piece 4112 and the second elastic piece 4122 to gradually deform away from each other. And during insertion, the first guide rail 4111 can cooperate with the first insertion slot 421 to slide, and the second guide rail 4121 can cooperate with the second insertion slot 422 to slide, jointly guiding the corresponding elastic pieces to deform. It can be understood that after being inserted in place, the first elastic piece 4112 and the second elastic piece 4122 can deform to press against the inner side wall of the corresponding insertion slot to achieve locking. When unlocking, just pull out the optical fiber module forcefully, without additional operations, and the above-mentioned matching structure is relatively simple and occupies little space.

[0060] It can be understood that the guide rail can also not be provided, and only elastic pieces are provided, and the insertion is realized through the cooperation between the elastic pieces and the insertion slots.

[0061] Refer to Figures 2 to 4 and Figure 8 and Figure 9 In some embodiments of the present invention, the first elastic piece 4112 is provided with a first clamping portion, the inner side wall of the first insertion slot 421 is provided with a second clamping portion, the first clamping portion can be clamped with the second clamping portion, the second elastic piece 4122 is provided with a third clamping portion, the inner side wall of the second insertion slot 422 is provided with a fourth clamping portion, and the third clamping portion can be clamped with the fourth clamping portion. It can improve the connection stability of the optical fiber module 300 without complicated disassembly and assembly steps.

[0062] Specifically, after the optical fiber module 300 is inserted in place, the first elastic piece 4112 can deform to make the first clamping portion and the second clamping portion clamped, and the second elastic piece 4122 can deform to make the third clamping portion and the fourth clamping portion clamped. Through the clamping cooperation, the connection stability can be further provided. When disassembly and assembly are required, just apply a greater force, and the first clamping portion and the second clamping portion can be separated from the clamping, and the third clamping portion and the fourth clamping portion can be separated from the connection, which can improve the connection stability of the optical fiber module 300 without complicated disassembly and assembly steps.

[0071] Specifically, the above-mentioned sixth latching portion 211 and the fifth latching portion 121 can be set as corresponding protruding blocks and grooves, and the specific structure will not be described in detail here. Three sixth latching portions 211 can be arranged at intervals on the slider 210, and are arranged at the front, middle and rear parts of the slider 210. When the sixth latching portion 211 at the front part is latched with the fifth latching portion 121, the carrier 200 can be roughly locked in the chassis main body 100. When the carrier 200 is pulled out to about half of its position, the sixth latching portion 211 in the middle can be latched with the fifth latching portion 121, so as to limit the shaking of the carrier 200 and facilitate the disassembly and assembly of the optical fiber module 300. When the carrier 200 is completely pulled out of the chassis main body 100, the sixth latching portion 211 at the rear part can be latched with the fifth latching portion 121. Through the above three sixth latching portions 211, the positioning of the carrier 200 at at least three positions can be realized, which is convenient for pulling and also convenient for maintaining the optical fiber module 300.
