Title: Terminal connecting construction for electrical parts
Inventor: TAKAHASHI HIDENORI
IPC: H05K1/14
Filed: 1988-02-19
Abstract: PURPOSE:To prevent destruction of a base plate, on which electric elements are mounted, even with eventual application of a force to electric lead terminals by incorporating such an arrangement that the electric lead terminals are not directly fixed to the base plate. CONSTITUTION:Electric lead terminals 2a-2f are fixed to a printed base plate 7 consisting of glass-epoxy material. These electric lead terminals 2a-2f are connected electrically to electric elements on a ceramic base plate 8 through holes 12a-12f for fixation of electric lead terminals in wiring patterns 11a-11f on the printed base plate 7, wiring patterns 11a-11f, ends 13a-13f for connection of edge grips of wiring patterns, edge grips 9a-9f, and electric wiring terminals 14a-14f. Thus the electric lead terminals 2a-2f are not fixed directly to the base plate 8 on which the electric elements are mounted, but fixed with another member interposed. Thereby a force eventually applied to the electric lead terminals 2a-2f will not act directly on the base plate on which the electric elements are mounted, to ensure that the base plate etc., are free from possible destruction and its mechanical strength is not deteriorated.
