    • 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.
    • 本发明涉及一种用于车辆的交流发电机的电气部件的引线的连接,并且提供适合于TIG焊接的端子形状(使用气体屏蔽的非消耗性电极的电弧焊接),而不受端子的尺寸精度的影响 相互连接。 在焊接区域附近设置具有比端子的焊接区域大的体积的十字形突起,并且基于由体积差引起的热容量的差异来控制焊接穿透(焊接深度),或者通过促进来抑制熔化 的热辐射。 因此,焊接深度稳定而不受包括它们之间的相对位置的端子的尺寸精度的影响,并且可以提供一种用于车辆的交流发电机,其中来自电气部件的引线具有高的连接可靠性。
