[0032] Specifically, the first shell 1 includes a first main body 11 and a first end 12 located on both sides of the first main body 11, and the second shell 2 includes a second main body 21 and a second end 22 located on both sides of the second main body 21. In the engaged state, the first shell 1 and the second shell 2 are surrounded by a receiving cavity for accommodating the end of the connector 5, and the first end 12 and the second end 22 are surrounded by an opening 4 connected to the receiving cavity.

When the two connectors 5 have a tendency to separate, the first reinforcing ribs 52 at both ends are close to the first end 12 and the second end 22 at both ends, respectively, to limit the separation of the two connectors 5. Preferably, the first reinforcing ribs 52 abut against the first end 12 and the second end 22.

[0050] Furthermore, after the adapter is engaged on the connector 5, in order to prevent relative rotation between the adapter and the connector 5, the connector 5 in this embodiment also includes a second reinforcing rib 53 and a third reinforcing rib 54. The second reinforcing rib 53 and the third reinforcing rib 54 are arranged along the axial direction of the connector body 51, and the second reinforcing rib 53 is perpendicular to the third reinforcing rib 54.
