Description

Technical Field

[0001] This utility model relates to the field of MPO connector technology, and more specifically, to an MPO push-pull connector. Background Technology

[0002] MPO fiber optic connectors are connection devices used to connect optical fibers to communication equipment. When existing MPO fiber optic connectors are used in ultra-high-density cabinets, due to the parallel connection of multiple rows of MPO connectors, unlocking the connector requires inserting fingers into the narrow gaps between the connectors and pinching the outer shell. Because of the distance between data interfaces, this can easily affect the MPO connectors around the target interface, and the cumbersome process of plugging and unplugging MPO connectors affects the efficiency of administrators. To address this, Chinese Patent Publication No. CN216870863U discloses an MPO fiber optic connector comprising a ferrule assembly, a housing, and a sheath. The ferrule assembly includes a housing, a connecting block fixedly mounted on one side of the housing, and a ferrule module on the side of the connecting block away from the housing. The ferrule module includes multiple sets of ferrules, with the ferrules equidistant. The connector is located on one side of the housing. The housing is fixedly installed on the side of the housing away from the connector block. A sheath is fixedly installed on the side of the housing away from the housing. The sheath contains an optical cable. One end of the optical cable is connected to the ferrule assembly, and the other end of the optical cable passes through the sheath and extends to the outside of the sheath. The surface of the housing is provided with a pull strap. By setting the pull strap, the conventional MPO fiber optic connector housing is replaced with a housing with a built-in pull strap. When inserting or removing the MPO fiber optic connector, there is no need to operate through a narrow space. Simply pull the pull strap and pull the housing to unlock it, thus achieving the advantage of easy insertion and removal of the MPO fiber optic connector. However, in the above MPO fiber optic connector structure, since the pull strap is exposed on the outside of the housing, after multiple MPO fiber optic connectors are plugged into communication equipment in an ultra-high density cabinet, there will be a mess. In addition, the pull strap will occupy the space on the outside of the MPO fiber optic connector and interfere with adjacent MPO fiber optic connectors. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an MPO push-pull connector in which the push-pull structure formed by the internal insert, opening slot and inverted buckle does not protrude from the outer side wall of the MPO connector, thereby avoiding interference between two adjacent MPO connectors and improving the neatness after multiple MPO fiber optic connectors are plugged into communication equipment in ultra-high density cabinets.

[0004] This utility model provides an MPO push-pull connector, including a connector body, a housing, and a tail sleeve. The housing is sleeved on the outside of the connector body, the rear end of the connector body is connected to an optical fiber, and the tail sleeve is movably sleeved on the optical fiber located at the rear end of the connector body. The front end of the tail sleeve abuts against the rear end of the connector body. The front end of the tail sleeve is provided with two vertically symmetrical inserts, and the rear end of the housing is provided with an opening slot corresponding to the two inserts. Each insert is inserted into the opening slot at the corresponding position from back to front. Each insert has a sliding groove on the left and right outer walls, and each opening slot has a buckle on the left and right inner walls. Each buckle is engaged in the sliding groove at the corresponding position and slides with the sliding groove.

[0005] By adopting the above-described structure, when the connector body needs to be removed from the communication device, pulling the tail sleeve allows each buckle to slide to the front end of the groove and abut against it. As the tail sleeve is continuously pulled, the outer shell and connector body disengage from the interface on the communication device, facilitating removal. When the connector body needs to be inserted into the communication device, the tail sleeve pushes it forward, allowing the front end of the connector body, along with the front end of the outer shell, to be inserted into the interface on the communication device, thus achieving insertion. Furthermore, since the push-pull structure formed by the insert block, slot, and buckles does not protrude from the outer wall of the MPO connector, interference between adjacent MPO connectors is avoided, and the neatness of multiple MPO fiber optic connectors after insertion into communication devices in ultra-high-density cabinets is improved. Additionally, compared to the pull-tab method used in existing technologies, the push-pull structure formed by the insert block, slot, and buckles offers higher reliability and stability.

[0006] In one possible implementation, each insert has a first rounded corner surface on the left and right outer walls of its front end. The first rounded corner surface is used to guide and engage with the rear edge of the inner end of the undercut so that the undercut can be fastened into the corresponding slot. Since each insert has a first rounded corner surface on its left and right outer walls of its front end, the first rounded corner surface can engage and guide with the rear edge of the inner end of the undercut during the insertion of the insert into the opening slot, so that the insert can be fastened into the opening slot and also facilitated by the undercut into the corresponding slot, thus making the assembly of the tail sleeve and the outer shell more convenient.

[0007] In one possible implementation, a second rounded corner surface is provided at the rear edge of each inner end of the buckle. The second rounded corner surface is used to cooperate with the outer edge of the front end of the insert block for guidance, so that the buckle can be fastened into the corresponding slot. Since a second rounded corner surface is provided at the rear edge of each inner end of the buckle, the second rounded corner surface can cooperate with the outer edge of the front end of the insert block for guidance during the process of inserting the front end of the insert block into the opening slot, so that the front end of the insert block can be inserted into the opening slot, and it is also convenient for the buckle to be fastened into the corresponding slot, which can facilitate the assembly of the tail sleeve and the outer shell.

[0008] In one possible implementation, a number of sets of openings are provided on the side wall of the rear part of the tail sleeve, which are spaced apart along the extension direction of the tail sleeve; each set of openings includes two openings symmetrically arranged on the side wall of the tail sleeve; by providing a number of sets of openings spaced apart along the extension direction of the tail sleeve on the side wall of the rear part of the tail sleeve, it is convenient to bend the tail sleeve, thereby facilitating the change of the fiber's output direction and avoiding damage to the fiber.

[0009] In one possible implementation, two adjacent openings in the extension direction of the tail sleeve are staggered along the circumferential direction of the tail sleeve; by adopting this structure, the rear part of the tail sleeve can be bent in multiple directions, thereby further changing the output direction of the optical fiber as needed, and avoiding damage to the optical fiber.

[0010] In one possible implementation, each opening extends circumferentially along the tail sleeve; by adopting this structure, since each opening extends circumferentially along the tail sleeve, it is convenient to further bend the rear of the tail sleeve so that the user can change the direction of the optical fiber output to meet the user's needs.

[0011] In one possible implementation, the rear end of the tail sleeve is provided with a ring-shaped wrapping part, which is used to wrap around the outside of the optical fiber. The wall thickness of the wrapping part is greater than the wall thickness of the tail sleeve. By providing the wrapping part, and because the wall thickness of the wrapping part is greater than the wall thickness of the tail sleeve, the wrapping part can reliably support the optical fiber and effectively prevent damage to the rear end of the tail sleeve.

[0017] See Figure 1-3 As shown in the figure, this application discloses an MPO push-pull connector, including a connector body 1, a housing 2, and a tail sleeve 3; the housing 2 is sleeved on the outside of the connector body 1, the rear end of the connector body 1 is connected to an optical fiber, the tail sleeve 3 is movably sleeved on the optical fiber located at the rear end of the connector body 1, and the front end of the tail sleeve 3 abuts against the rear end of the connector body 1; the front end of the tail sleeve 3 is provided with two vertically symmetrical insertion blocks 31, and the rear end of the housing 2 is provided with an opening slot 21 corresponding to the two insertion blocks 31, and each insertion block 31 is inserted into the opening slot 21 at the corresponding position from back to front; each insertion block 31 has a sliding groove 311 on the left and right outer walls, and each opening slot 21 has a buckle 22 on the left and right inner walls, and each buckle 22 is fastened into the sliding groove 311 at the corresponding position and slides in cooperation with the sliding groove 311.

[0018] Each insert 31 has a first rounded corner surface 312 on the left and right outer walls of its front end. The first rounded corner surface 312 is used to cooperate with the rear edge of the inner end of the buckle 22 for guidance so that the buckle 22 can be fastened into the corresponding groove 311. Since each insert has a first rounded corner surface on the left and right outer walls of its front end, the first rounded corner surface can cooperate with the rear edge of the inner end of the buckle for guidance during the insertion of the front end of the insert into the opening groove, so that the front end of the insert can be inserted into the opening groove, and the buckle can be fastened into the corresponding groove, which can facilitate the assembly of the tail sleeve and the outer shell.

[0019] Each buckle 22 has a second rounded corner surface 221 at the rear edge of its inner end. The second rounded corner surface 221 is used to guide and cooperate with the outer edge of the front end of the insert 31 so that the buckle 22 can be fastened into the corresponding groove 311. Since each buckle has a second rounded corner surface at the rear edge of its inner end, the second rounded corner surface can cooperate and guide the front end of the insert into the opening groove during the process of inserting the front end of the insert into the opening groove, so that the front end of the insert can be inserted into the opening groove, and it is also convenient for the buckle to be fastened into the corresponding groove, which can facilitate the assembly of the tail sleeve and the outer shell.

[0020] The rear sidewall of the tail sleeve 3 is provided with several sets of openings that are spaced apart along the extension direction of the tail sleeve 3; each set of openings includes two openings 32 that are symmetrically arranged on the sidewall of the tail sleeve 3; by providing several sets of openings that are spaced apart along the extension direction of the tail sleeve on the rear sidewall of the tail sleeve, it is easy to bend the tail sleeve, thereby making it easy to change the output direction of the optical fiber and avoiding damage to the optical fiber.

[0021] Two adjacent openings 32 in the extension direction of the tail sleeve 3 are staggered along the circumferential direction of the tail sleeve 3. By adopting this structure, the rear part of the tail sleeve can be bent in multiple directions, thereby further changing the output direction of the optical fiber as needed, and avoiding damage to the optical fiber.

[0022] Each opening 32 extends along the circumferential direction of the tail sleeve 3. With this structure, since each opening extends along the circumferential direction of the tail sleeve, it is convenient to further bend the rear part of the tail sleeve so that the user can change the output direction of the optical fiber to meet the user's needs.

[0023] The tail sleeve 3 has a ring-shaped wrapping part 33 at its rear end. The wrapping part 33 is used to wrap around the outside of the optical fiber. The wall thickness of the wrapping part 33 is greater than the wall thickness of the tail sleeve 3. By setting the wrapping part, and because the wall thickness of the wrapping part is greater than the wall thickness of the tail sleeve, the wrapping part can reliably support the optical fiber and effectively prevent damage to the rear end of the tail sleeve.

[0024] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
