Resilient plug and a watertight connector

摘要

A rubber plug ( 8 ) has a tubular main portion ( 8 A) and a wire inserting hole ( 5 ) penetrates the main portion ( 8 A) along a central axis (C) for receiving a wire (W). The main portion ( 8 A) includes an inner lip portion ( 13 ) and an outer lip portion ( 14 ) having lips ( 12 ) circumferentially formed on the inner and outer circumferential surfaces of the main portion ( 8 A). A tapered entanglement preventing portion ( 8 B) extends from an opening edge ( 17 ) of the wire insertion hole ( 5 ) to a rear peripheral edge ( 13 A) of the outer lip portion ( 13 ). Another wire (W) slides on the tapered surface ( 16 ) to avoid entanglement.
