Patent number: 5545047Abstract: In a connector of male and female interlocking terminals, a lever is provided on a first connector in a freely pivoting manner. Guide pins provided on a second connector are inserted to guide channels formed in the first connector. A stopper block is provided on the top wall of the first connector. A spring is connected between the back side of the lever and the back side on the top wall of the first connector. The lever is pulled by the spring against the stopper block and is held at a disengaging position in which guide grooves formed inside the lever and the guide channels are aligned to form an inlet for the guide pins. Since the lever is automatically returned to the disengaging position by the spring even if the lever is accidentally turned, it is not necessary to re-rotate the lever to the disengaging position, making connecting operation smoothly.Type: GrantFiled: July 25, 1994Date of Patent: August 13, 1996Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Hajime Okada, Masashi Saito
