As a possible embodiment, in order to increase the connection strength between the mounting baffle 21 and the inner wall of the rear housing 2, a reinforcing rib (not shown) may be provided at the connection between the mounting baffle 21 and the inner wall of the rear housing 2, and in order to avoid interference of the reinforcing rib with the insertion and extraction movement of the OPS module 4, the reinforcing rib may be provided at the side of the mounting baffle 21 facing away from the mounting space 219. It will be appreciated that the number of reinforcing ribs may be plural, and that the plurality of reinforcing ribs may be arranged at intervals along the length direction of the mounting baffle 21, so that the risk of crushing and breakage of the mounting baffle 21 when the OPS module 4 is inserted into the mounting baffle 21 can be reduced.

Alternatively, referring to fig. 7, considering that the OPS module 4 is mainly subjected to the gravity of the OPS module 4 by the lower mounting baffle 21 during the insertion, the friction force of the OPS module 4 and the lower mounting baffle 21 is large, and thus, the sliding protrusion 211 may be provided on the upper surface of the lower mounting baffle 21 among the two mounting baffles 21, and the length of the sliding protrusion 211 in the insertion direction of the OPS module 4 may be smaller than the length of the mounting baffle 21, and/or the width of the sliding protrusion 211 in the direction perpendicular to the insertion direction of the OPS module 4 may be smaller than the width of the mounting baffle 21, and the lower surface of the OPS module 4 may be supported on the upper surface of the sliding protrusion 211 and slidably engaged with the sliding protrusion 211. In this way, the contact area between the sliding protrusion 211 and the lower surface of the OPS module 4 can be ensured to be small, and the friction force is also small, so that the insertion process of the OPS module 4 can be smoother.

For example, the length of the sliding protrusion 211 may be smaller than the length of the mounting baffle 21, the width of the sliding protrusion 211 may be smaller than the width of the mounting baffle 21, the length of the sliding protrusion 211 may be smaller than the length of the mounting baffle 21, and the width of the sliding protrusion 211 may be smaller than the width of the mounting baffle 21, so that the contact area between the sliding protrusion 211 and the lower surface of the OPS module 4 may be ensured to be smaller, the friction force may be smaller, the insertion process of the OPS module 4 may be smoother, and in addition, the material may be saved.
