Patent number: 7404722Abstract: A lever type connector comprises two connector housings, a front holder, a movable guide member fixed within one of the connector housings, and a movable guide member slidably attached to another of the connector housings. The movable guide member protects male terminals at a temporary holding position and is slid by the front holder toward an end position during connection. A elastic arm for temporarily holding the movable guide member is provided within the connector with the male terminals. A release projection is provided on the front holder. A space for stowing the elastic arm, which has restored its bending, is secured behind the release projection. According to the lever type connector can prevent plastic deformation of the elastic arm for temporary holding of the movable guide member without forming an access hole by a telescoping shutoff of injection molding.Type: GrantFiled: October 26, 2007Date of Patent: July 29, 2008Assignee: Yazaki CorporationInventors: Kenichi Ikeya, Ronald Alan Cabangal, Hideki Inoue
