Abstract:
A construction for waterproof sealing a connector coupling gap comprising:a housing; a connector portion provided integrally with the housing and formed at least partly in a column shape; a wire harness connector coupled with the connector portion with a coupling gap; a tubular shaped grommet made of resilient material and put on an outside circumferential surface of the connector portion to seal the connector coupling gap; a plurality of locking convex portions provided spaced around the outside circumferential surface of the connector portion; and a plurality of locking concave portions provided spaced around an inside circumferential surface of the grommet, wherein, at least at the plurality of the convex portions, the grommet is resiliently outwardly deformable when the grommet is pushed onto the connector portion and resiliently returnable to a pre-outwardly deformable state when the plurality of the locking concave portions are completely inserted into the locking convex portions respectively so that the grommet may be rigidly fixed to the connector portion, wherein the housing is provided with a base unit and a bridging portion connecting the base unit and a part of the circumferential surface of the connector portion, the locking convex portions are arranged on the connector portion except for the outside circumferential surface of the connector portion axially extending from the bridging portion, the grommet is provided with a cut to prevent interference with the bridging portion when the grommet is placed on the connector portion and the locking concave portions are arranged around the connector portion except for the inside circumferential surface of the grommet axially extending from the cut and, further, wherein at least a part of the outside circumferential surface of the grommet axially extending from the cut contacts with and is inwardly pressed against a surface of the base unit when the grommet is placed on the connector portion so that the circumferential surface of the grommet is rigidly fixed around a substantial percentage of the circumference of the connector portion.
