摘要： A vehicle alternator is disclosed having a stator, a rotor, a frame surrounding the stator and the rotor, a bowl-shaped end cover mounted on the frame and defining an electric component-part compartment, a brush unit held in sliding contact with slip rings of a rotary shaft, and a rectifier unit. The rectifier unit includes an insulating terminal block radially extending in face-to-face relation to the one end face of the frame, a positive-side cooling fin carried on one surface of the insulating terminal block, and a negative-side cooling fin carried on the other surface of the insulating terminal block. At least one of the insulating terminal block and the end cover has a heat shield plate member laterally extending through a radial space between the cooling fins and the brush unit in a direction substantially parallel to the axis of the rotary shaft.

The end wall section has a centrifugal-blade-facing portion axially facing the centrifugal blades, and a coil-end-facing portion axially facing the rear coil end. The coil-end-facing portion is bent at a predetermined curvature radius and extending from the centrifugal-blade-facing portion to the cooling air discharge opening. The inner end surface of the coil-end-facing portion is formed with a recess located axially rearwardly of a radial extension line of an inner end surface of the centrifugal-blade-facing portion.

摘要： In an AC generator for a vehicle, an end cover has two types of parts, one-type part is away from a rib part in a positive cooling fin, and the other-type part is close to the rib part. The rib part projects toward the end cover side. The one-type part is thinner than the other-type part in the end cover in order to reduce the variation of thermal expansion in each part of the end cover. This configuration increases anti-thermal fatigue of the end cover.

摘要： An alternator for a vehicle is provided which is equipped with a rectifier. The rectifier includes a positive-side radiator fin in which a positive rectifying device is installed. An output terminal through which dc voltage is outputted has a rectangular head and is fit in a through hole formed in the positive-side radiator fin. Ribs are formed on the positive-side radiator fin across the through hole. The rectangular head of the output terminal is shaped to have two sides and a diagonal line. The diagonal line is longer than an interval between the ribs. The sides are located at a distance away from each other which is smaller than the interval between the ribs. Specifically, the ribs serve as stoppers on which corners of the head hits when excessive torque acts on the output terminal, thereby minimizing deformation of the positive-side radiator fin and undesirable rotation of the output terminal.
摘要翻译： 提供一种车辆的交流发电机，其配备有整流器。 整流器包括正侧散热片，其中安装有正整流装置。 输出直流电压的输出端子具有矩形头部，并且配合在形成于正侧散热片的通孔中。 肋在正侧散热器翅片上穿过通孔形成。 输出端子的矩形头被成形为具有两侧和对角线。 对角线长于肋之间的间隔。 侧面位于彼此远离肋骨间隔的距离处。 具体地说，当过大的转矩作用在输出端子上时，这些肋条用作头部的角落的止动器，从而最小化正侧散热器翅片的变形和输出端子的不希望的旋转。
