Patent number: 7520765Abstract: A female housing (10) has a lever (12) to facilitate connection with a male housing (11). An operable portion (43) of the lever (12) is at a lateral end of the female housing (10) immediately before the housings (10; 11) are connected and is operated along a connecting direction of the male housing (11). An engaging portion (53) is formed at an end of the lever (12) opposite the operable portion (43) and is engageable with a locking projection (52) on the male housing (11) immediately before the housings (10, 11) are connected properly. Thus, the locking projection (52) receives a force acting along the connecting direction of the male housing (11) as the lever (12) is rotated. In this way, the posture of the female housing (10) is corrected, enabling the two housings (10, 11) to be connected in their proper postures.Type: GrantFiled: November 26, 2007Date of Patent: April 21, 2009Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Yukihiro Fukatsu, Toshikazu Sakurai, Masayasu Fujii

Patent number: 7445491Abstract: A lever (40) formed with a cam groove (41) is rotatably mounted and a detecting terminal (60) is mounted in a female housing (10). The detecting terminal (60) contacts contact terminals (98) in the female housing (10) to close a detecting circuit only when the housings (10, 80) are connected properly. A pressing portion (44) projects from part of a cam plate (47) of the lever (40) facing the detecting terminal (60), and keeps pressing the detecting terminal (60) to deform the detecting terminal 60 to a position where the detecting terminal (60) is separated from the contact terminals (98) while the lever (40) is rotated until the housings (10, 80) are connected properly. The pressed state is canceled to enable the detecting terminal (60) to contact the contact terminals (98) when the lever 40 is rotated to a position where the housings (10, 80) are connected properly.Type: GrantFiled: October 3, 2006Date of Patent: November 4, 2008Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Masayasu Fujii, Toshikazu Sakurai, Atsushi Sakatani

Patent number: 7445474Abstract: A lever (30) can be assembled in either of two postures symmetrical with respect to an axis of symmetry (19), and the rotating direction of the lever (30) changes depending on the assembling posture. Thus, the rotating direction of the lever (30) can be selected depending on circumstances. A cam follower (52) can enter a cam groove (33) regardless of the posture in which the lever (30) is assembled. The lever (30) can be held at a standby position by a holder (21L, 21R, 22, 34, 36), and the lever (30) can be locked at a connection position by a lock (21L, 21R, 23L, 23R, 39, 41).Type: GrantFiled: November 4, 2005Date of Patent: November 4, 2008Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Atsushi Sakatani, Yoshihiro Uchiyama, Toshikazu Sakurai
