Abstract
An object of the present invention is to provide a rotary electric machine that can improve the reliability of a connection terminal by preventing brazing material applied to butting portions of the connection terminal from flowing out. The rotary electric machine according to the present invention has, on at least one of the inner and outer circumferences of a hole portion 22 of a connection terminal 20, a groove portion 22a, 22b, 22c, 22d, or 22e that can prevent brazing material 24 from flowing out from between butting portions 23, thereby solving a problem that a crack occurs on the connection terminal upon fusing of the connection terminal and a lead conductive wire.
Claims9
A rotary electric machine comprising:
- a conductive wire having an insulation coating;
- and
- a connection terminal joined with the conductive wire, wherein
- the connection terminal has a tube-shaped hole portion having no discontinuity, which is formed by rolling metallic plate material to be butted and joining butting portions via brazing material through brazing work, so that the conductive wire inserted into the hole portion is joined with the connection terminal by fusing, and
- a groove portion that can prevent the brazing material from flowing out from between the butting portions is provided on at least one of the inner circumference and the outer circumference of the hole portion of the connection terminal.
