发明名称 Weld joining portion of a vehicle alternator
摘要 The invention concerns with connection of a lead from an electrical component of an alternator for a vehicle, and provides a terminal shape suitable for TIG welding (arc welding using a gas shielded non-consumable electrode) without being affected by dimensional accuracy of terminals to be connected to each other. Cross-shaped projections having a larger volume than a welded region of the terminal is provided near the welded region, and weld penetration (welding depth) is controlled based on a difference in heat capacity resulting from the volume difference, or melting is suppressed with promotion of heat radiation. Thus, the welding depth is stabilized without being affected by dimensional accuracy of the terminals including relative positions between them, and an alternator for a vehicle can be provided in which a lead from an electrical component has high connection reliability.
