In this embodiment, the latch structure 2 includes a supporting element 20, a first coupling structure 21 and a second assembly structure 22. The supporting element 20 has a first side A and a second side B. The first coupling structure 21 is located on the second side B of the supporting element 20, and the first coupling structure 21 has a first alignment structure 210, the shape of which may be determined according to requirements, and is not limited thereto. The first coupling structure 21 has a first coupling hole 211 and a second coupling hole 212 for coupling with the optical connector. It should be noted that in this embodiment, the first alignment structure 210 is disposed on the wall of the first coupling hole 211, but it is not limited thereto, and may also be disposed on the wall of the second coupling hole 212. Alternatively, there is a first alignment structure 210 disposed on both the wall of the first coupling hole 211 and the second coupling hole 212.

[0030] The second assembly structure 22 is disposed on the supporting element 20 and extends toward the first side A. The second assembly structure 22 is used to combine with the first assembly structure (not shown) in the optical receptacle, and the detailed description would be described later. In this embodiment, the second assembly structure 22 has a first assembly member 22A and a second assembly member 22B, which are respectively disposed at the two end portions 20A and 20B of the supporting element 20. In this embodiment, two end portions 20A and 20B are located at the upper end and lower end of the supporting element 20. A second alignment structure 220 is disposed on one of the first assembly members 22A. It should be noted that the second alignment structure 220 does not have to be disposed on the first assembly member 22A. In another embodiment, it may also be disposed on the second assembly member 22B or on both the first assembly member 22A and the second assembly member 22B.

[0031] In addition, it should be noted that the positions of the first alignment structure 210 and the second alignment structure 220 are not limited to the position shown in FIGS. 1A and 1B. For example, as shown in FIG. 1C, which is a schematic front view of the position relationship between the first coupling hole 211 and the first alignment structure 210 or between the first assembly member 22A and the second alignment structure 220. In the FIG. 1C, the solid line represents the current position of the first alignment structure 210 shown in

[0032] FIG. 1A or the second alignment structure 220 shown in FIG. 1B, and the dashed line represents other possible position of first alignment structures 210 and second alignment structures 220. Each position represents that only the optical connector matched with the position may be inserted. It should be noted that, although the first alignment structure 210 in this embodiment is a convex structure, in another embodiment, it may also be a concave structure, which is determined according to the user's needs and not limited thereto.

[0033] In this embodiment, as shown in FIG. 1A, an extending arm 23 is extended from one end portion 20A of the supporting element 20 toward the second side B, and the extending arm 23 has identification features. In an embodiment, the identification feature may be a color, for example, the supporting arm 23 has a specific color, or there is an identifiable color on a specific area of the supporting arm 23. In another embodiment, an identification structure 230 may be a text or a specific pattern. The extending arm 23 further has a first fastener 231, and an end of the extending arm 23 has a second fastener 232, and an end surface of the extending arm 23 has an identification structure 230. Located on the opposite side of the extending arm 23, there is a first guiding plate 24A extended toward the first side A, and at the end portion 20B of the supporting element 20, there is a second guiding plate 24B extended toward both the first side A and the second side B. The first guiding plate 24A has a first guiding body 240, and the second guiding plate 24B has a second guiding body 241, the function of which would be described later.

[0034] Please refer to FIGS. 2A to 2C, in which FIG. 2A is a three-dimensional schematic diagram of an optical receptacle, FIG. 2B is a partial exploded cross-sectional schematic diagram of the housing of the optical receptacle, and FIG. 2C is a schematic cross-sectional diagram of the optical receptacle. The optical receptacle 3 includes a housing 30 with a first insertion hole 30A and a second insertion hole 30B on both sides, respectively. The housing 30 has an accommodation space 30C and at least one first assembly structure 31. In this embodiment, the first assembly structure 31 is integrally formed with the housing 30 and has a leaning surface 310 and a plurality of assembly members 311. It should be noted that the latch structure 2 is inserted into the accommodation space 30C of the housing 30 through the first insertion hole 30A, wherein the first assembly member 22A and the second assembly member 22B of the latch structure 2 are respectively connected to the corresponding assembly members 311 of the first assembly structure 31, and the surface of the supporting element 20 of the latch structure 2 and the leaning surface 310 are leaned against each other. After the first assembly member 22A and the second assembly member 22B are combined with the first assembly structure 31, at the second insertion hole 30B, the first assembly member 22A and the second assembly member 22B are combined with the corresponding coupling members 311 to form a second coupling structure 32, which is used for coupling with the optical connector inserted through the second insertion hole 30B, and the first coupling structure 21 is used for coupling with the optical connector inserted through the first insertion hole 30A.

[0035] The housing 30 has a first buckle groove 300, and the extending arm 23 has the first fastener 231 at a position corresponding to the first buckle groove 300. When the latch structure 2 is installed in the housing 30, the first fastener 231 is used to be embedded into the first buckle groove 300. In addition, the housing 30 has a second buckle groove 301, and the extending arm 23 has the second fastener 232 at a position corresponding to the second buckle groove 301. When the latch structure 2 is installed in the housing 30, the second fastener 232 is embedded into the second buckle groove 301. There is an identification structure 230 on the surface of the second fastener 232.

[0036] Please refer to FIGS. 3A and 3B, in which FIG. 3A is a schematic diagram of a viewing angle from the first insertion hole of the housing in the present invention, and FIG. 3B is a schematic diagram of a viewing angle from the second insertion hole of the housing in the present invention. In this embodiment, referring to FIGS. 2B and 3A to 3B at the same time, there is a first guiding groove 33 above each first assembly structure 31 of the second insertion hole 30B, and the first guiding groove 33 is formed by two first protruding blocks 330 and a top surface inside the housing 30. When the latch structure 2 is inserted into the housing 30, the first guiding plate 24A is embedded into the first guiding groove 33, and the first guiding body 240 on the first guiding plate 24A is embedded into a space between the two first protruding blocks 330 to achieve an engaging effect. Similarly, at the first insertion hole 30A, there is a second guiding groove 34 corresponding to the bottom of each first assembly structure 31, which is formed by two second protruding blocks 340 and the bottom surface of the housing 30. When the latch structure 2 is inserted into the housing 30, the second guiding plate 24B is embedded into the second guiding groove 34, and the second guiding body 241 on the second guiding plate 24B is embedded into a space between the two second protruding blocks 340 to achieve an engaging effect.

[0037] Next, the operation mode is going to be explained. Please refer to FIGS. 4A and 4B, in which FIG. 4A is a schematic diagram of the optical receptacle with different latch structures in the present invention, and FIG. 4B is a schematic diagram of the optical connector matching with the latch structure of the optical receptacle in the present invention. The first insertion hole 30A has two insertion slots 30D and 30E. Each insertion slot 30D and 30E is equipped with latch structure 2a and 2, respectively. Each latch structure 2 and 2a has a different identification feature, which is a color. For example, the color of the latch structure 2 and 2a are different, which may be directly understood by the user. The latch structures 2 and 2a further have identification structures 230 and 230a, which may be different texts or patterns. In addition, it may also be seen from FIG. 4A that the first alignment structures 210 and 210a on the adjacent latch structures 2 and 2a are at different positions, so that the first coupling structures 21 and 21a are limited to be inserted by the optical connectors having a corresponding alignment groove (FIG. 4B). For example, the optical connector 4 shown in FIG. 4B has a guiding hole 40 and an alignment groove 41. The alignment groove 41 in this embodiment corresponds to the first alignment structure 210 of the latch structure 2. Therefore, the optical connector 4 may only be inserted into the insertion slot 30E to be combined with the corresponding first coupling structure 21, but may not be inserted into the insertion slot 30D to be combined with the first alignment structure 21a.

[0038] It should be noted that although FIG. 4A is illustrated with the first insertion hole 30A, according to the same logical concept, as shown in FIGS. 2B and 2C, the second alignment structure 220 of the adjacent latch structure 2 in the second insertion hole 30B may also have different configuration, which may restrict the insertion by only the optical connector with the corresponding configuration.

[0039] In conventional technology, the user or the manufacturer must know the order of the alignment features that cannot be changed in advance, so that each specific optical connector can be correctly inserted into the corresponding receptacle. However, the latch structure of the present invention is designed to be detachable, for example: the latch structure 2 or 2a in FIG. 4A, so that the user may assemble a suitable latch structure into the optical receptacle as needed to solve the problem of the conventional technology. In addition, through visually identification features or structures, such as alignment structure, color or text, the user can install the latch structure into the optical receptacle and the features of the insertion slot can be distinguished through visual recognition. The corresponding optical connector can be quickly and unambiguously selected and inserted into the corresponding optical receptacle, which increases the convenience of use and operation.

[0040] It will be understood that the above description of embodiments is given by way of example only and that various modifications may be made by those with ordinary skill in the art. The above specification, examples, and data provide a complete description of the present invention and use of exemplary embodiments of the invention. Although various embodiments of the invention have been described above with a certain degree of particularity, or with reference to one or more individual embodiments, those with ordinary skill in the art could make numerous alterations or modifications to the disclosed embodiments without departing from the spirit or scope of this invention.
