Abstract:
1. A watertight connector, comprising: a housing with opposite front and rear ends, an accommodation recess formed in the rear end of the housing, the accommodation recess having a rearwardly facing base and a peripheral wall extending rearwardly from the base, cavities extending forward from the base of the accommodation recess for receiving terminal fittings secured to ends of wires; a resilient plug in the accommodation recess, the resilient plug having a front surface facing the base of the accommodation recess, and a rear surface facing rearwardly from the housing, an outer peripheral surface extending between the front and rear surfaces, wire insertion holes extending through the resilient plug from the front surface to the rear surface and substantially aligned with the cavities, a holder-side groove in the rear surface of the resilient plug between the outer peripheral surface and the wire insertion holes so that the holder-side groove substantially surrounds all of the wire insertion holes, the holder-side groove being tapered gradually to narrower dimensions at locations farther from the rear surface; and a plug holder assembled with the rear end of housing to hold the resilient plug in the accommodation recess, window holes formed through the plug holder and aligned respectively with the wire insertion holes of the resilient plug, and a pressing member formed on the plug holder and having a tapered shape substantially corresponding to a tapered shape defined by the holder-side groove in the resilient plug, the pressing member being engaged in the holder-side groove of the resilient plug for urging the outer peripheral surface of the resilient plug into sealed engagement with the peripheral wall of the accommodation recess.
