Voltage controller of alternator for vehicle

Abstract

A voltage controller has an integrated control circuit having a plurality of lead wires, a plurality of connecting terminals, and a terminal holding body holding the terminals such that a portion of each terminal is protruded from a surface of the body so as to be connected with one lead wire. The control circuit controls an output voltage of an alternator by receiving or outputting signals transmitted through the lead wires and the connecting terminals. The protruded terminals are disposed so as to be aligned along a plurality of lines on the surface of the body. Therefore, an on-surface distance between terminals adjacent to each other is sufficiently set at a large value, and the arrangement of the terminals prevents the terminals from being short-circuited.
