  • Connector and method of assembling it
    Patent number: 6685496
    Abstract: A connector includes a waiting-side housing (10) with a receptacle (14) for receiving a watertight housing (11). A grommet (21) and a grommet cover (22) are mounted on the watertight housing (11). A seal (31) with lips (31A) is formed at a portion of the grommet (21) projects toward the waiting-side housing (10). A squeezing wall (30) is provided at the back end of the receptacle (14) and is fittable over the seal (31). Thus, the lips (31A) are compressed in directions normal to a connecting direction between the squeezing wall (30) and the watertight housing (11) during a connecting operation, to provide sealing between the housings (10, 11).
