Terminal engagement structure for a connector

摘要

A retainer guide groove having guiding faces which are in parallel with a direction of inserting the retainer into a connector housing and opposed to each other is formed in an inner side face of a side wall of the connector housing. A retainer insertion direction restricting arm having guided faces is formed in the retainer. The guided faces are guided in the retainer guide groove while being respectively in sliding contact with the opposing guiding faces of the retainer guide groove when the retainer is to be inserted into the connector housing. A terminal engagement portion is disposed in the retainer. The terminal engagement portion prevents a connecting terminal which is provisionally inserted into the terminal housing chamber of the connector housing when the retainer is provisionally positioned with respect to the connector housing, from slipping off from the terminal housing chamber.
