Connecting device for mechanical and electrical interconnection of e.g. lithium polymer elements in lithium ion battery utilized in auxiliary drive for wheelchair, has electrode contacts stretched between circuit board and counter-element

摘要

The device has a printed circuit board (PCB-A) comprising a contact unit with contacting areas (A1, A2), and a counter-element (PCB-B) that is stretchable against the circuit board, where the counter element is designed as another printed circuit board. The former circuit board and the counter-element are arranged such that electrode contacts (L1, L2) are stretched between the contacting areas of the former board and the counter element. The former board and the counter-element comprise an electrode contact passage opening (S), which is designed as a feed through-opening or insertion opening.
