Terminal device of coil

摘要

A first terminal and a second terminal are provided, in which a winding terminal of a coil is connected to the first terminal and one end of the second terminal is positioned to overlap one end of the first terminal. One end of each terminal is connected by a soldered portion 12. One end of the first terminal is designed to serve as an engaging projection which is bent at a generally right angle to the longitudinal direction thereof. The engaging projection engages an engaging opening formed on one end of the second terminal. A constricted part is formed near the engaging opening to reduce heat escape. Because the first terminal and the second terminal are firmly secured to each other, a soldered portion is not affected by stress resulting from differences in the coefficients of thermal expansion of the terminals, the solder and the resin due to a change in application temperature and therefore, the reliability of the soldered connection is improved.
