[0038] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in combination with the specific embodiments of the utility model and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0039] The technical solutions disclosed in various embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0040] Please refer to Figures 1 to 16 The embodiment of the utility model discloses a fiber optic socket assembly, and the disclosed fiber optic socket assembly includes a socket module 100 and an extension module 200. The socket module 100 can be a socket module 100 capable of installing an optical splitter, or a socket module 100 with a fiber splicing function or a fiber storage function. The embodiment of the application does not specifically limit the type of the socket module 100.

[0041] The socket module 100 includes a socket housing 110, a first optical fiber adapter group, and a first clamping portion 130. The socket housing 110 can provide a base for installing other components of the socket module 100. The first optical fiber adapter group can be composed of a plurality of first optical fiber adapters 120. The plurality of first optical fiber adapters 120 can include a first optical fiber adapter 120 connected to an input optical fiber and a first optical fiber adapter 120 connected to an output optical fiber. There can be a plurality of first optical fiber adapters 120 connected to an output optical fiber.

[0042] At least part of the first optical fiber adapter group is disposed in the socket housing 110, and the adapter interface of the first optical fiber adapter group can be exposed on the surface of the socket housing 110. The first clamping portion 130 is disposed on the socket housing 110, and the first clamping portion 130 can be disposed on the socket housing 110 by bonding, welding, bolt connection, etc., and the embodiment of the present application does not specifically limit the arrangement of the first clamping portion 130.

[0043] It should be noted that the socket module 100 capable of installing an optical splitter may include a large number of first optical fiber adapters 120 in its first optical fiber adapter group. For example, the first optical fiber adapter group may have six first optical fiber adapters 120, and the six first optical fiber adapters 120 may include one first optical fiber adapter 120 connected to the input optical fiber and five first optical fiber adapters 120 connected to the output optical fiber, thereby forming a 1:5 socket module 100, wherein the 1 in 1:5 represents the number of first optical fiber adapters 120 connected to the input optical fiber, and the 5 in 1:5 represents the number of first optical fiber adapters 120 connected to the output optical fiber. Of course, the socket module 100 may also be a 1:8 socket module 100 or a 1:9 socket module 100, and the embodiment of the present application does not impose any specific restrictions on the structure of the socket module 100.

[0044] The socket module 100 with a fiber-splitting function or a fiber-storing function needs to reserve a corresponding space in the socket housing 110 because it needs to be able to store optical fibers or support the fiber-splitting function. Therefore, the number of the first optical fiber adapters 120 of the socket module 100 with a fiber-splitting function or a fiber-storing function is relatively small. For example, the number of the first optical fiber adapters 120 can be two, one of which can be the first optical fiber adapter 120 connected to the input optical fiber, and the other can be the first optical fiber adapter 120 connected to the output optical fiber, thereby forming a 1:1 socket module 100. Of course, the socket module 100 can also be a 1:2 socket module 100 or a 1:3 socket module 100, etc. The embodiment of the present application does not specifically limit the structure of the socket module 100.

[0045] The expansion module 200 includes a module body 210 and a second clamping portion 220. The module body 210 may be a module body 210 capable of installing an optical splitter, or a module body 210 having a fiber splicing function or a fiber storage function. The embodiment of the present application does not specifically limit the type of the module body 210. The structure of the module body 210 capable of installing an optical splitter and the module body 210 having a fiber splicing function or a fiber storage function may refer to the structure of the socket module 100, and the embodiment of the present application will not be repeated.

[0046] The second clamping portion 220 is disposed on the module body 210 . The second clamping portion 220 can be disposed on the module body 210 by bonding, welding, bolt connection, etc. The embodiment of the present application does not specifically limit the arrangement method of the second clamping portion 220 .

[0047] The module body 210 can be connected to the socket housing 110 through the snap-fitting cooperation between the second snap-fitting portion 220 and the first snap-fitting portion 130, and is used to expand the functions of the socket module 100. The extended functions of the module body 210 can be determined according to the type of the module body 210. For example, when the module body 210 is a module body 210 on which a splitter can be installed, the extended function of the module body 210 can be to improve the splitting capability of the socket module 100; when the module body 210 is a module body 210 with a fiber splicing function or a fiber storage function, the extended function of the module body 210 can be to improve the fiber storage capability of the socket module 100 or to add a fiber splicing function.

[0048] In the embodiment of the present application, the optical fiber socket assembly is configured to include a socket module 100 and an extension module 200, and the socket module 100 is configured to include a socket housing 110, a first optical fiber adapter group and a first clamping portion 130, and the extension module 200 is configured to include a module body 210 and a second clamping portion 220, so that the module body 210 can be connected to the socket housing 110 through the clamping fit between the second clamping portion 220 and the first clamping portion 130, so that the module body 210 can expand the function of the socket module 100, thereby solving the problem that the optical fiber socket assembly in the related art has a single function and cannot meet the diverse needs of users.

[0049] Optionally, the socket housing 110 may include a shell body 111 and a cover body 112. The shell body 111 may have a first installation space and a first installation port 111a connected to the first installation space. At least part of the first optical fiber adapter group may be arranged in the first installation space through the first installation port 111a. The first clamping portion 130 is arranged on the shell body 111, and when the cover body 112 is separated from the shell body 111, the module body 210 may be buckled in the first installation port 111a through the clamping fit of the second clamping portion 220 and the first clamping portion 130.

[0050] The optical fiber socket assembly disclosed in the embodiment of the present application is configured such that the socket housing 110 includes a shell body 111 and a cover body 112, so that when the cover body 112 is separated from the shell body 111, the module body 210 can be snapped onto the first mounting opening 111a through the snap-fitting engagement of the second snap-fitting portion 220 and the first snap-fitting portion 130, thereby blocking the first mounting opening 111a through the module body 210, thereby protecting the first optical fiber adapter group located in the socket housing 110.

[0051] Specifically, the optical fiber socket assembly can have a first assembly state and a second assembly state. In the first assembly state, the cover body 112 can be separated from the shell body 111, and the module body 210 can be buckled in the first installation opening 111a through the snap-fitting of the second snap-fitting portion 220 and the first snap-fitting portion 130, so that the first installation opening 111a is blocked by the module body 210, and the first optical fiber adapter group located in the socket shell 110 can be protected.

[0052] In the second assembly state, the module body 210 can be separated from the shell body 111, and the cover body 112 can be snapped onto the first mounting port 111a by snapping together the third snap-fitting portion 112a and the first snap-fitting portion 130. Thus, when the socket module 100 does not need to expand its functions, the first mounting port 111a can be blocked by the cover body 112, thereby protecting the first optical fiber adapter group located in the socket shell 110.

[0053] In an optional embodiment, the extension module 200 may further include a fourth clamping portion 230, and the module body 210 may include a module housing 211 and an extension function group. The module housing 211 may provide an installation basis for other components of the module body 210, and the extension function group may be a second optical fiber adapter group, and the second optical fiber adapter group may include a plurality of second optical fiber adapters 212. Of course, the extension function group may also be other function groups, and the embodiment of the present application does not specifically limit the type of the extension function group.

[0054] The module housing 211 may have a second installation space and a second installation opening 211c communicating with the second installation space, at least part of the extended functional group may be disposed in the second installation space, and the second clamping portion 220 and the fourth clamping portion 230 may be disposed in the module housing 211. When the module body 210 is buckled in the first installation opening 111a by the clamping fit of the second clamping portion 220 and the first clamping portion 130, the second installation opening 211c may face the side away from the shell body 111, and the cover body 112 may be covered in the second installation opening 211c by the clamping fit of the third clamping portion 112a and the fourth clamping portion 230.

[0055] In the fiber optic socket assembly disclosed in the embodiment of the present application, when the module body 210 is snap-fitted to the first mounting opening 111a by the second snap-fitting portion 220 and the first snap-fitting portion 130, the cover body 112 is covered on the second mounting opening 211c, so that the cover body 112 can protect the extended functional group located in the second mounting space.

[0056] It should be noted that setting the shell body 111 to have a first installation space and a first installation port 111a connected to the first installation space, and setting the module shell 211 to have a second installation space and a second installation port 211c connected to the second installation space, can facilitate the installation of the first fiber optic adapter group and the extended function group.

[0057] Optionally, the module housing 211 may include a first housing 211a and a second housing 211b, and the first housing 211a may be connected to the second housing 211b. The first housing 211a may have a first protection space and a first insertion port 211a1 communicating with the first protection space, and the second housing 211b may have a second installation space and a second installation port 211c communicating with the second installation space.

The first housing 211a may be buckled on the shell body 111 from the side where the first installation port 111a is located through the first insertion port 211a1, so that the shell body 111 is located in the first protection space. The cover 112 can be buckled on the second shell 211b from the side where the second installation opening 211c is located through the second insertion opening 112b, so that the second shell 211b is located in the second protection space.

[0058] The optical fiber socket assembly disclosed in the embodiment of the present application is configured such that the module housing 211 is configured to include a first housing 211a and a second housing 211b, so that the first housing 211a can have a first protection space and a first insertion port 211a1 communicating with the first protection space, and the second housing 211b has a second installation space and a second installation port 211c communicating with the second installation space, thereby enabling the first housing 211a to be buckled onto the shell body 111 from the side where the first installation port 111a is located through the first insertion port 211a1, thereby enabling the first housing 211a to wrap at least a portion of the shell body 111, thereby protecting the wrapped portion of the shell body 111. The cover body 112 is configured to have a second protective space and a second insertion port 112b connected to the second protective space, so that the cover body 112 can be buckled on the second shell body 211b from the side where the second installation port 211c is located through the second insertion port 112b, so that the cover body 112 can wrap at least a portion of the second shell body 211b, so that the cover body 112 can protect at least a portion of the second shell body 211b, and the connection by buckling can not only improve the stability of the assembly, but also improve the overall strength of the optical fiber socket assembly.

[0059] Optionally, the fiber optic receptacle assembly may include a plurality of extension modules 200. The shell body 111 and at least some of the extension modules 200 may be stacked in sequence, and the shell body 111 may be snap-fitted with the second snap-fitting portion 220 of an adjacent extension module 200 through the first snap-fitting portion 130, so that the shell body 111 is connected to the adjacent extension module 200. Two adjacent extension modules 200 may be connected through the snap-fitting of the second snap-fitting portion 220 and the fourth snap-fitting portion 230, so that the two adjacent extension modules 200 are connected. The cover body 112 may be snap-fitted with the fourth snap-fitting portion 230 of the adjacent extension module 200 through the third snap-fitting portion 112a, so that the cover body 112 is connected to the adjacent extension module 200.

[0060] The fiber optic receptacle assembly disclosed in the embodiment of the present application is provided with a plurality of extension modules 200, so that the shell body 111 and at least some of the plurality of extension modules 200 can be stacked in sequence, thereby further improving the diversity of the functions of the fiber optic receptacle assembly.

[0061] The extended functions of the multiple extension modules 200 may be the same or different, and the embodiment of the present application does not impose any specific limitation on the extended functions of the multiple extension modules 200.

[0062] In order to avoid the cover body 112 and the module housing 211 of the adjacent expansion module 200 from being buckled without restriction when connected, optionally, in the case where the module housing 211 includes a first housing 211a and a second housing 211b, the first housing 211a and the second housing 211b may have a limiting boss 211d at the connection, and the limiting boss 211d may protrude from the second housing 211b and be arranged around the second housing 211b. The limiting boss 211d may be used to contact with the port of the second insertion port 112b in the buckling direction to avoid the cover body 112 and the module housing 211 of the adjacent expansion module 200 from being buckled without restriction when connected.

[0063] In order to prevent the module housings 211 of adjacent expansion modules 200 from being buckled indefinitely when connected, optionally, the limiting boss 211d can be used to limit contact with the port of the first insertion port 211a1 of the adjacent expansion module 200 in the buckling direction, thereby preventing the module housings 211 of adjacent expansion modules 200 from being buckled indefinitely when connected.

[0064] Specifically, one of the first clamping portion 130 and the second clamping portion 220 may be a clamping protrusion, and the other may be a clamping groove. One of the third clamping portion 112a and the fourth clamping portion 230 may be a clamping protrusion, and the other may be a clamping groove. When the first clamping portion 130 and the second clamping portion 220 are clamped, or when the third clamping portion 112a and the fourth clamping portion 230 are clamped, or when the second clamping portion 220 and the third clamping portion 112a are clamped, the clamping protrusion may be clamped into the clamping groove, and when separation is required, the separation may be achieved by applying external force to pull.

[0065] The optical fiber socket assembly disclosed in the embodiment of the present application makes it easier to snap-fit ​​the first snap-fit ​​portion 130 and the second snap-fit ​​portion 220, and the third snap-fit ​​portion 112a and the fourth snap-fit ​​portion 230, by setting one of the first snap-fit ​​portion 130 and the second snap-fit ​​portion 220 as a snap-fit ​​protrusion and the other as a snap-fit ​​groove, and one of the third snap-fit ​​portion 112a and the fourth snap-fit ​​portion 230 as a snap-fit ​​protrusion and the other as a snap-fit ​​groove.

[0066] It should be noted that one of the second clamping portion 220 and the fourth clamping portion 230 needs to satisfy the requirement that one of them is a clamping protrusion and the other is a clamping groove. The first clamping portion 130, the second clamping portion 220, the third clamping portion 112a and the fourth clamping portion 230 can all be arranged on the side wall of the corresponding housing perpendicular to the buckling direction. The first clamping portion 130, the second clamping portion 220, the third clamping portion 112a and the fourth clamping portion 230 can all be multiple. Of course, the first clamping portion 130, the second clamping portion 220, the third clamping portion 112a and the fourth clamping portion 230 can also be one. The embodiment of the present application does not specifically limit the number of the first clamping portion 130, the second clamping portion 220, the third clamping portion 112a and the fourth clamping portion 230.

[0067] Of course, the first clamping portion 130, the second clamping portion 220, the third clamping portion 112a and the fourth clamping portion 230 may also be other structures, and the embodiment of the present application does not make specific restrictions on the first clamping portion 130, the second clamping portion 220, the third clamping portion 112a and the fourth clamping portion 230.

[0068] Optionally, the extension module 200 may include a module housing 211 and an extension function group, and the second clamping portion 220 may be disposed in the module housing 211. At least part of the extension function group may be disposed in the module housing 211, and the extension function group is a second optical fiber adapter group.

[0069] Specifically, the second fiber adapter group may be composed of a plurality of second fiber adapters 212, and the plurality of second fiber adapters 212 may include a second fiber adapter 212 connected to an input fiber and a second fiber adapter 212 connected to an output fiber, and the second fiber adapter 212 connected to an output fiber may be multiple. For example, the second fiber adapter group may have 6 second fiber adapters 212, and the 6 second fiber adapters 212 may include 1 second fiber adapter 212 connected to an input fiber and 5 second fiber adapters 212 connected to an output fiber, so that a 1:5 extension module 200 may be formed, wherein 1 in 1:5 represents the number of second fiber adapters 212 connected to an input fiber, and 5 in 1:5 represents the number of second fiber adapters 212 connected to an output fiber. Of course, the extension module 200 may also be a 1:2 extension module 200 or a 1:8 extension module 200, and the embodiment of the present application does not specifically limit the structure of the extension module 200.

[0070] Specifically, the fiber optic receptacle assembly may include a plurality of extension modules 200 , and the number of second fiber optic adapters 212 corresponding to the second fiber optic adapter groups of the plurality of extension modules 200 is different.

[0071] The fiber optic socket assembly disclosed in the embodiment of the present application sets the number of second fiber optic adapters corresponding to the second fiber optic adapter groups of the multiple extension modules 200 to be different, so that some of the multiple extension modules 200 can be used as extension modules 200 that can be installed with a splitter, and some of the extension modules 200 can be used as extension modules 200 with a fiber melting function or a fiber storage function, thereby making the fiber optic socket assembly more versatile in terms of extended functions.

[0072] In another embodiment, the extension module 200 may include a module housing 211, the second clamping portion 220 may be disposed on the module housing 211, the module housing 211 may have a fiber storage slot, and the fiber storage slot may be used to store optical fiber cables, so that the optical fiber socket assembly may have a fiber storage function.
