Abstract

The invention pertains to an electrical contact element composed of a perforated piece of sheet metal that has a connection region (3) for an electrical connection on one end and a contact region (2) with a polygonal cross-sectional spring-arm base (7) with smooth walls on the other end, where to form a contact casing (1) with a polygonal plug hole (15) defining the contact sites, at each of the front edges of the walls of the spring arm base (7) turned away from the connection area (3), at least one spring arm (14) extending in the direction of the plug hole (15) is provided; the spring arms (14) extend toward each other as far as the plug hole (15) and form it, and then are bent away at an angle to the outside to form a positioning funnel (10) for a contact plug pin in the front free end region.
