Abstract: A protective cap is used when a male inner housing to which male terminals and electric wires are attached is passed through a bellows-shaped tubular portion of a grommet. A male outer housing mounted on an annular seal portion of the grommet and the male inner housing accommodated in the male outer housing in a state where the male inner housing accommodates and holds the male terminals connected to the electric wires constitutes the connector. The protective cap includes a circular cap main body having an accommodating recess that accommodates tab portions of the male terminals protruding more than a front face of the male inner housing, at least a front side of the male inner housing being fitted into the accommodating recess. An outer diameter of the cap main body is smaller than an inner diameter of the bellows-shaped tubular portion.

Abstract: Provided is a connector unit which can prevent damage to respective parts during rotation of a lever member. A fitting portion of a female outer housing fits with a to-be-fitted portion of a male outer housing, wherein timing of the fitting is after timing of insertion of a guide projection into a guide groove and timing of releasing of a restriction arm by a release projection. Fitting of the fitting portion with the to-be-fitted portion allows an operator to feel a change in force required for operation during moving the male outer housing and the female outer housing toward each other. By rotating the lever member after the operator felt the change in the force, damage to the guide projection and the restriction arm and such can be prevented.
