Dynamo-electric machine for automobile, has three-phase electric wire terminals fixed at end surfaces of relay units at opposite ends with respect to coupling supports by screwing nuts on external screw thread parts of output terminal pins

摘要

The machine has stator terminals (33) fixed between head parts and coupling supports (26) in a surface contact state by screwing relay units (27) on external screw thread parts of output terminal pins (25). Three-phase electric wire terminals (34a) are fixed in a surface contact state with the end surfaces of the units (27) at the opposite ends with respect to the supports by screwing nuts (35) on the screw thread parts. Insulating tubes (30b) are inserted between the units (27) and extraction openings (31) to cover outer sides of the units (27).
