It is to be understood that in the description of the present utility model, the axial line direction of the floating plug 100 extends in the first direction Z, and the circumferential direction of the floating plug 100 refers to the direction around the axial line thereof, and is not limited to a cylindrical or elliptic cylindrical plug.

With this arrangement, the first housing 110 and the second housing 120 can be allowed to have floating margins in both the first direction Z and the second direction X of the floating plug 100, improving the reliability of the floating plug 100.

In other embodiments, L1 may be the same as L2, considering only the floating margins of the first and second cases 110 and 120 in the first direction Z; or w1=d2, only the play margins of the first and second cases 110 and 120 in the second direction X are considered.
