  • Patent number: 11909447
    Abstract: An optical transceiver module includes a first housing, a second housing, an engagement component, a conductive body, and a circuit board. The first housing has a first sidewall and a first groove. The first groove is closer to a central line of a major axis of the first housing than the first sidewall. The second housing is assembled with the first housing. The second housing has a second sidewall. The second sidewall is extended into the first groove. The engagement component has a first engagement portion. The first engagement portion is extended between the first sidewall and the second sidewall. The conductive body is disposed between the first groove and the second sidewall. The circuit board is disposed between the first housing and the second housing to perform photoelectric conversion. Therefore, the stroke of the engagement component can be fixed, and the electromagnetic interference can be reduced.
