Abstract

An electrical contact element including a perforated piece of sheet metal that has on one end a connection region (3) for an electrical connection and on the other end a contact region (2) with a polygonal cross-sectional spring-arm base (7) with smooth walls. The walls of the spring arm base have front edges in the direction facing away from the connection region, from which extend at least one spring arm to form a contact casing with a polygonal plug hole defining contact sites. The spring arms extend toward each other as far as the location of the plug hole to form that hole, and then are bent away at an angle to the outside to form a positioning funnel for a contact plug pin in the front free end region of the spring arms.
