Strain relief for flex foil

Abstract:

A battery connection assembly includes a frame including a plurality of posts that are spaced by a first distance. A flex foil includes a conductive layer and first and second insulating layers arranged adjacent to the conductive layer. A first plurality of traces is defined in the conductive layer. A plurality of fingers is defined in the conductive layer and partially released from the flex foil, wherein the first insulating layer is removed from the plurality of fingers to expose the conductive layer. A plurality of busbars is connected to the frame and including a first surface, a second surface and a hole from the first surface to the second surface. The plurality of fingers is attached to the first surfaces of the busbar at an attachment location and wherein adhesive in the hole attaches the flex foil to the busbar adjacent to the attachment location.
