Connector with secondary locking

摘要

In installing a retainer (20) on a connector housing (10), a guide portion (21A) formed on a removal prevention portion (21) fits in the connector housing (10) before a holding piece (22) reaches the connector housing (10). In this manner, the retainer (20) is placed in position. Therefore, it does not occur that the front end of the holding piece strikes against the outer surface of the connector housing. Consequently, it is possible to prevent the holding piece (22) from striking against the connector housing (10) and thus prevent it from being deformed or damaged. In the state where the retainer (20) has been locked at the locking position, the guide portion (21A) penetrates through the connector housing (10) and substantially contacts the seal ring (13), thus preventing the removal of the seal ring (13). Thus, it is possible to reliably prevent the removal of the seal ring (13) by the guide portion (21A) without providing the connector housing (10) with a removal prevention component part separately from the guide portion (21A). <IMAGE>
