Electrical conductor track made of metal

摘要

An electrical conductor track made of metal has a weak point with a notch (6) which is provided in the top (8), runs to a tip and has two edges (20, 22) which meet at an apex (a vertex) (21) which runs in a straight line. The first edge (20) runs at a steeper angle than the second edge (22) which, with a continuous profile, is concave and has a curvature which reduces from the apex (21) in the direction of the top (8). <IMAGE>
