1. An electrical interconnection arrangement comprising
a circuit board (20),
a generally three-dimensional contact element (44; 80) having a base part (46; 82) facing said circuit board, said base part comprising flat portions (84, 86) extending parallel to said circuit board (20) and having a predetermined footprint;
an electrical conductor path (22) applied to the surface of said circuit board facing said contact element, and adapted to the shape of said footprint;
a solder connection (74) extending between said conductor path (22) and said flat portions extending parallel to the circuit board;
passthrough openings (24, 26, 28, 30, 32) located within a perimeter defined by edges of said conductor path (22);
metallized portions provided at
at least one end of said passthrough openings (24, 26, 28, 30, 32);
feet (34, 36, 38, 40, 42; 88, 90, 92, 94) provided on said contact element (44; 80), said feet being redirected by bending to match associated passthrough openings, and pressed into these associated passthrough openings;
solder connections between said pressed-in feet and said associated metallized portions;
a contact tongue (54; 96) resiliently articulated on said base part (46; 82) and forming an insertion opening (64) between said contact tongue (54; 96) and said base part (46; 82) for insertion of an electrical conductor (66) into said insertion opening (64) and for connecting it to said contact element (44; 80).
