Electrical contact element

Electrical contact element comprising:

• a perforated piece of sheet metal that has a connection region (3) on one end for an electrical connection and a contact region (2) with a polygonal cross-sectional spring-arm base (7) with smooth walls on the other end;
• the walls of the spring arm base (7) having front edges facing away from the connection region (3);
• at least one spring arm (14) extending from each front edge of the polygonal spring arm base to form a contact casing (1) with a polygonal plug hole (15) whereat the spring arms are in mutually spaced-apart relation defining contact sites;
• and wherein
• the spring arms (14) extend toward each other as far as the location of the plug hole (15) so as to form the plug hole, and then bend away at an angle to the outside to form a positioning funnel (10) for a contact plug pin in a front free end region of the spring arms.
