Waterproof connector with blind recess

Abstract

To improve the sealing function of a waterproof connector provided with a collective rubber stopper. Male terminal fittings 21 at ends of electric wires 20 are pushed through electric wire through holes 33 of a collective rubber stopper 30, widening these electric wire through holes 33 while they are being pushed therethrough, and are inserted into corresponding cavities 16. Inner lips 35 of the rubber stopper 30 fit resiliently with outer circumference faces of the electric wires 20, thereby sealing each cavity 16. A ring-shaped groove 37 is formed concentrically around each electric wire through hole 33 at a posterior face of the rubber stopper 30. Inner portions of these grooves 37 form comparatively thin cylindrical members 38, these fitting tightly with the outer circumference of the electric wires 20. Even in the case where a pulling force is exerted on the electric wires 20 when these have been bent at a right angle to their axial direction, the cylindrical members 38 follow the bending of the electric wires 20, thus maintaining a tight and reliable seal between inner circumference faces of the cylindrical members 38 and the outer circumference faces of the electric wires 20.
