Abstract
A contact spring assembly for the self-locking contacting of a wire () of an electrical conductor includes a support wall () made of a conductive material and a contact spring (). The contact spring () has a base leg () held stationary with respect to the support wall and a clamping leg () which, together with the support wall (), forms an insertion receptacle () for the wire () of the conductor. The insertion receptacle is tapered in the insertion direction. The base leg () of the contact spring transitions into a holding leg ('), which is inserted into a receiving shaft () stationary with respect to the support wall () and has two detent projections (), which protrude perpendicularly to the base leg in opposite directions and are locked to mating contours () on the walls of the receiving shaft.
