Patent number: 7407398Abstract: A lever type electrical connector includes an insulating housing provided with a least one terminal and a mating face that receives a complementary mating connector. A cam plate is arranged on the insulating housing and is moveable in a sliding direction substantially perpendicular to a mating direction of the complementary mating connector. A lever is mounted on the insulating housing. The lever has a shaft extending substantially perpendicular to the sliding direction and the mating direction and is rotatable about the shaft between an open position and a closed position to move the cam plate in the sliding direction. An elastically deformable bearing section is provided on the insulating housing and supports the shaft. A reinforcement member is removably attached to the bearing section and abuts the bearing section such that the reinforcement member receives a force applied from the shaft to the bearing section when the lever is rotated.Type: GrantFiled: September 13, 2007Date of Patent: August 5, 2008Assignees: Tyco Electronics AMP K.K., Toyota Jidosha Kabushiki KaishaInventors: Seiji Shishikura, Kazushige Sakamaki, Yoshiro Kakuda
