Lötaufbau zwischen einem Streifen einer Stromschiene und einem bedruckten Substrat

摘要

A soldering structure between a tab of a bus bar and a printed substrate is disclosed to provide a soldering structure between a tab of a bus bar and a printed substrate that causes no crack. An electrical conductive material is formed on a printed substrate. A tab through-hole is provide to penetrate the electrical conductive material and printed substrate. A tab formed by bending a body of the bus bar enters the tab through-hole. A periphery of the tab and the electrical conductive material are interconnected by soldering. A stress-absorbing aperture or recess is provided in an insulation plate on which the body of the bus bar is mounted. The stress-absorbing aperture or recess can absorb an axial stress caused in the tab.
