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. ## Claims ### Claim 1 An optical transceiver module, comprising: a first housing having a first sidewall and a first groove, wherein the first groove is closer to a central line of a major axis of the first housing than the first sidewall; a second housing assembled with the first housing, wherein the second housing has a second sidewall, and the second sidewall is extended into the first groove; an engagement component having a first engagement portion, wherein the first engagement portion is extended between the first sidewall and the second sidewall; a conductive body disposed between the first groove and the second sidewall; and a circuit board disposed between the first housing and the second housing to perform photoelectric conversion, wherein the second housing further has a fifth sidewall, and the fifth sidewall is butted with the first sidewall. ### Claim 2 (depends on 1) The optical transceiver module according to claim 1, wherein the first engagement portion is a strip-shaped engagement portion. ### Claim 3 (depends on 1) The optical transceiver module according to claim 1, wherein a wall of the first groove is protruded from a surface of the first housing or not protruded from the first housing. ### Claim 4 (depends on 1) The optical transceiver module according to claim 1, wherein the first housing further has a third sidewall and a second groove, and the second housing further has a fourth sidewall, and wherein the second groove is closer to the central line of the major axis of the first housing than the third sidewall, and the fourth sidewall is extended into the second groove. ### Claim 5 (depends on 4) The optical transceiver module according to claim 4, wherein the engagement component further has a second engagement portion, and the second engagement portion is extended between the third sidewall and the fourth sidewall. ### Claim 6 (depends on 1) The optical transceiver module according to claim 1, wherein the first housing further has a third sidewall, and the second housing further has a fourth sidewall and a second groove, and wherein the second groove is closer to a central line of a major axis of the second housing than the fourth sidewall, and the third sidewall is extended into the second groove. ### Claim 7 (depends on 6) The optical transceiver module according to claim 6, wherein the first housing further has a sixth sidewall, and the sixth sidewall is butted with the fourth sidewall. ### Claim 8 (depends on 6) The optical transceiver module according to claim 6, wherein the engagement component further has a second engagement portion, and the second engagement portion is extended between the third sidewall and the fourth sidewall. ### Claim 9 (depends on 1) The optical transceiver module according to claim 1, wherein an assembly of the first housing and the second housing is pluggably installed to a system connector, the system connector has a rectangular opening and a plurality of spring plates, and the plurality of spring plates are peripherally disposed around the rectangular opening. ### Claim 10 (depends on 9) The optical transceiver module according to claim 9, wherein the first housing and the second housing commonly define four sides, the four sides are in contact with the plurality of spring plates, and the first engagement portion and the plurality of spring plates are isolated by the first housing and the second housing.
