  • Patent number: 11581683
    Abstract: A connector with a grommet includes a housing and a grommet. A panel hooking portion, a flange, and a locking projection are formed on an outside of the housing. The grommet includes a panel contact part that comes into tight contact with an edge of a mounting hole of a panel. A flexible arm is formed on the flange so as to protrude from the flange. The locking projection is provided at a front of the flexible arm. A sensing part configured to sense whether the locking projection is locked to the panel, is provided at a rear of the flexible arm so as to protrude outward than the flange. The sensing part is received in a receiving part formed on the panel contact part. When the locking projection is not locked to the panel, the sensing part and the receiving part tilt.
