Patent attributes
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.
