Patent number: 4683390Abstract: An improved terminal structure for an automotive AC generator particularly designed to reduce the axial space required for connection with an external member, thereby improving connectability. The generator includes a housing rotatably supporting a rotary shaft thereof, and a rectifier accommodated in the housing and having an output terminal assembly. The output terminal assembly comprises an axial output terminal member disposed axially within the housing and having its one end projected outwardly from the housing in the axial direction, and a radial output terminal member connected at its one end with that end of the axial output terminal member projected from the housing. The radial output terminal member extends radially along the outer peripheral surface of the housing and has its other end extending substantially perpendicular to the axis of the rotary shaft for connection with an external member.Type: GrantFiled: April 9, 1986Date of Patent: July 28, 1987Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Hideo Imori, Katsumi Adachi

Patent number: 4543504Abstract: A rectifier has a pair of heat dissipating plates at the positive (+) side and the negative (-) side which constitute a full-wave rectification circuit and are positioned in mutual confrontation with a small gap between them, and an insulating material to electrically insulate the both heat dissipating plates. A recessed portion is formed in each of the mutually opposed parts of the both heat dissipating plates; a noise-preventing capacitor element is housed in a closed space defined by the recessed portions to make an outer covering for the capacitor, and the capacitor element and each of the heat dissipating plates are electrically connected.Type: GrantFiled: November 14, 1983Date of Patent: September 24, 1985Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Yoshiyuki Iwaki, Hideo Imori, Hitoshi Gotou
