Bus bar structure
First Claim
Patent Images
1. A method of manufacturing a bus bar structure, comprising:
- providing a continuous bus bar comprising a first pattern portion and a second pattern portion, the second pattern portion being spaced from the first pattern portion by a predetermined distance;
providing a tab terminal, the tab terminal comprising;
a bent leg portion in a first plane, and a standing portion in a second plane intersecting the first plane, the standing portion connected to the bent leg portion at a line of intersection of the first plane and the second plane, the standing portion having a length longer than the predetermined distance;
positioning the tab terminal such that the bent leg portion is in contact with the first pattern portion and the standing portion is oriented facing the second pattern portion such that, if the standing portion were bent about the line of intersection toward the second pattern portion, the standing portion would contact the second pattern portion; and
attaching the bent leg portion to the first pattern portion.
