Due to the tight connection of the receptacle module and the plug module, the contact stability of the receptacle terminals 610 and the plug terminals 620 can also be ensured.

Simply, the first shield 310 does not come out of the range even if axial movement occurs due to the interference of the projection 111 and the stepped end surface 250 of the third shield 330/the plug member 200, and particularly, a positioning groove may be provided on the inner wall of the insertion end or the connection hole 110 to further restrict the axial movement of the first shield 310.
