Aluminium tape to lead through connection formation for electrolytic capacitor

摘要

The method initially involves production of a bulge using a suitable tool on the lead-through (1) in the region of the exit point from the termination disk (2). The aluminium tape is subsequently laid on the lead-through and punched out by a stamp having a smaller bore hole diameter than the diameter of the lead-through. A projection (10) is produced by the punching out whose diameter corresponds to the bore hole of the stamp. The part of the projection which projects above the aluminium tape is finally deformed into a rivet head (13).
