Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments of the utility model, and it should be understood that the utility model is not limited to the exemplary embodiments described here. Based on the embodiments of the utility model described in the utility model, all other embodiments obtained by those skilled in the art without creative work should fall within the protection scope of the utility model.

[0032] In view of the problem that the existing split design of the optical interface requires the shell to accurately limit and assemble the adapter, which leads to great difficulty in design, processing and assembly of the optical interface, the utility model proposes an optical interface adapter unit, an optical interface component and an optical module, which can effectively reduce the difficulty in design, processing and assembly of the optical interface, which are described in detail below.

[0033] First, refer to Figure 1 and 2 The optical interface adapter unit according to the embodiment of the utility model is described.

[0034] like Figure 1 and 2 As shown, the optical interface adapter unit 10 includes a housing 11 and an optical interface adapter 12;

[0036] One end of the inner side of the shell 11 has an opening, and the other end is provided with at least one second limiting portion and at least one first limiting portion in sequence along the first direction D1, and at least one first accommodating groove is formed between the first limiting portion and the second limiting portion; when the optical interface adapter 12 is connected to the shell 11 through the connecting portion 120, the first accommodating groove is used to accommodate the connecting portion 120.

[0037] In the present invention, the optical interface adapter 120 may be a multi-fiber push-on (MPO) optical interface adapter, or other optical interface adapters. The present invention does not specifically limit the model of the adapter.

[0038] In the present invention, when a plurality of first cavities and a plurality of second cavities are provided inside the optical interface adapter 120 along the first direction D1, the first cavities in the optical interface adapter 120 are arranged in parallel, and the second cavities are also arranged in parallel.

[0039] Correspondingly, a plurality of first limiting portions and a plurality of second limiting portions are sequentially arranged in parallel along the first direction D1 on the inner side of the housing 11 , and a first accommodating groove is formed between each first limiting portion and each second limiting portion.

[0040] The optical interface adapter unit 10 in the utility model realizes the connection and fixation between the housing and the optical interface adapter through the connecting portion 120 and the first limiting portion, the second limiting portion, and the first accommodating groove, thereby effectively reducing the design difficulty, processing difficulty and assembly difficulty of the optical interface.

[0041] Please continue reading Figure 1 and 2 In a specific implementation, in order to facilitate installation, the housing 11 includes a first sub-housing 111 and a second sub-housing 112, and the first sub-housing 111 and the second sub-housing 112 are detachably connected.

[0042] Exemplarily, the first sub-shell 111 and the second sub-shell 112 are correspondingly provided with a connector 101 and a connecting hole, and the connector 101 may include screws 1011, 1012, 1013, and 1014, and accordingly, the connecting port is a threaded hole (not shown in the figure).

[0043] For another example, the first sub-shell 111 and the second sub-shell 112 can also be connected by a bayonet, and buckles and slots are respectively provided on the two correspondingly connected structural members. It should be noted that there are many ways to implement detachable connection, and the specific connection method is not limited to this and can be selected according to actual needs.

[0044] Please continue reading Figure 1 and 2 In a specific implementation, the optical interface adapter unit 10 also includes a pull ring 13, the pull ring 13 includes a pull ring body 131, a first fixing portion 132 and a second fixing portion 133, the first fixing portion 132 and the second fixing portion 133 are arranged on both sides of the pull ring 13 and extend along the first direction D1.

[0045] The pull ring 13 is detachably connected to the housing 11. The pull ring 13 and the housing 11 can be connected in a variety of ways, for example, through a connecting piece and a connecting hole; preferably, the pull ring 13 and the housing 11 are connected by a snap-fitting manner. Figure 2 The card connection method is described in detail.

[0046] like Figure 2 As shown, the housing 11 includes a first sub-housing 111 and a second sub-housing 112. The first sub-housing 111 has first limiting grooves 11101 extending along the first direction D1 on both sides, the second sub-housing 112 has second limiting grooves 11201 extending along the first direction D1 on both sides, and the upper part of the second sub-housing 112 has a third limiting portion 11202, and the first limiting groove 11101, the second limiting groove 11201 and the third limiting portion 11202 are used to fix the pull ring 13.

[0047] It should be noted that when the pull ring 13 is installed, part of the structure of the pull ring 13 is located between the shell 11 and the optical interface adapter 12, so that the third limit portion 11202 and the optical interface adapter 12 jointly limit the position of the pull ring 13 and prevent it from moving along the first direction D1.

[0048] Next, refer to Figure 3a-3dThe optical interface adapter according to the embodiment of the present utility model is described.

[0049] like Figure 3a As shown, the optical interface adapter 12 of the embodiment of the utility model is a two-port adapter, and the distance between the two ports is 10.2 mm.

Optionally, the first sub-shell 111 is provided with a plug hole 1115 for detachably connecting with the second sub-shell 112.

Optionally, the second sub-shell 112 is provided with a plug 1125, which is used to be plugged into the jack 1115 of the first sub-shell 111, so that the first sub-shell 111 is detachably connected to the first sub-shell 111.

[0058] The internal structures of the first sub-housing 111 and the second sub-housing 112 can be symmetrically arranged, so the structures of the first sub-housing 111 and the second sub-housing 112 are substantially the same, thereby further reducing the difficulty of designing, processing and assembling the optical interface.

[0059] See also Figure 3c , Figure 3d , Figure 4a and Figure 4b During installation,

Similarly, when the second optical fiber connector 22 is inserted into the optical interface adapter 12, the side 21b of the fourth limiting portion contacts the side 12b of the optical interface adapter 12.
