摘要： PROBLEM TO BE SOLVED: To provide a shape of a terminal used for connection to leading wires led from the electrical component of a vehicle alternator, which is suitable for a Tig welding method (a non-consumable electrode gas shield arc welding method) and can be welded to the terminals to be connected of the leading wires without being affected by dimensional accuracy between the terminals to be connected.
SOLUTION: A terminal having this shape is formed in a cross shape of which the extended portions are formed at a position close to the welding portion of the terminal such that they have a lager area than that of the welding portion, then it makes possible to control the penetration depth of welding because the terminal has a larger volume, then lager heat capacity than those of the welding portion, which also makes the penetration depth stable without being affected by dimensional accuracy between terminals to be connected. As an extended portion for welding is bent toward a terminal to be connected, the terminal can be easily aligned as well as a melting-amount-limitation effect can be controlled.

摘要翻译：要解决的问题：提供一种用于连接从车辆交流发电机的电气部件引出的引线的端子的形状，其适用于Tig焊接方法（非消耗性电极气体保护电弧焊接方法），并且可以焊接到要连接的引线的端子，而不受要连接的端子之间的尺寸精度的影响。解决方案：具有这种形状的端子形成为十字形，其延伸部分形成在靠近端子的焊接部分的位置，使得它们具有比焊接部分的更大的面积，然后它由于终端具有较大的体积，所以能够控制焊接的穿透深度，因此能够比焊接部的热容量大，因此不会受连接端子间的尺寸精度的影响而使穿透深度稳定。随着焊接的延伸部分朝向要连接的端子弯曲，端子可以容易地对准，并且可以控制熔化量限制效果。版权所有（C）2007，JPO＆INPIT
