Terminal connection for a rotating electrical machine for vehicle

摘要

In a rotating electrical machine for vehicle, at least one of a rectifier device, a voltage regulator, and a brush holder includes an external terminal connection portion provided with an insert terminal inserted into resin and an insert nut inserted into the resin and superimposed on the insert terminal. The insert terminal includes a contact portion on a surface on a side opposing the insert nut and the insert terminal and the insert nut are superimposed via the contact portion and inserted into the resin. It thus becomes possible to provide a rotating electrical machine for vehicle provided with constituent components that are free from an inconvenience caused by a variance over time.

主权项

1. A rotating electrical machine for vehicle, comprising:
a stator provided with a stator winding; a rotor provided with a field winding that generates a flux interlinked with the stator winding and inducing an AC electromotive force in the stator winding when driven to rotate; a rectifier device converting the AC electromotive force to DC power; a voltage regulator regulating magnitude of the induced AC power; and a brush holder holding a brush that supplies a rotor winding of the rotor with a current, wherein: at least one of the rectifier device, the voltage regulator, and the brush holder includes an external terminal connection portion provided with an insert terminal inserted into resin and an insert nut inserted into the resin and superimposed on the insert terminal; the insert terminal includes a contact portion on a surface on a side opposing the insert nut; the insert terminal and the insert nut are superimposed via the contact portion and inserted into the resin; and the contact portion provided to the insert terminal is formed of a protrusion protruding toward the insert nut.
