Patent number: 5599211Abstract: A fixed terminal hingably supports a movable terminal of a terminal device. A terminal screw passes through a hole in the fixed terminal to engage a threaded hole in the movable terminal. A captivating device prevents the terminal screw from being withdrawn from the fixed terminal. The terminal screw, when tightened, clamps an element to be connected between the fixed and movable terminals. The captivating device, when the terminal screw is loosened, urges the movable terminal away from the fixed terminal to separate the two, thereby positively releasing the element connected therebetween.Type: GrantFiled: September 8, 1995Date of Patent: February 4, 1997Assignee: Emuden Musen Kogyo Kabushiki KaishaInventors: Yoshio Kurahashi, Susumu Henmi
