Abstract
A contact spring includes a bottom spring having a centrally disposed spring arm base formed by a rectangular frame. A connection part is formed onto one end of the spring arm base, for electrical conductors. Two spring arms are each formed onto broad sides of the spring arm base on the opposite end. The spring arms converge in a wedge-like manner toward a free end and after that widen into a plug-in funnel. The spring arms are each kept spaced apart in the region of the contact zone by respective indentations oriented toward one another and disposed on long edges. A detent sleeve surrounds the spring arm base and the spring arms formed thereon. An opening angle of the plug-in funnel, over its entire length, is .alpha..ltoreq.30. The spring arms are shaped spherically in the vicinity of the contact zone and each form a respective contact dome.
