Abstract

An electrical contact device includes a first electrical contact portion mechanically fixing and electrically connecting the electrical contact device to a circuit board by press-fitting, a second electrical contact portion forming an electrical plug contact matable with an electrical mating contact element, and a spring portion arranged between the first and second electrical contact portions in a longitudinal direction of the electrical contact device. The second electrical contact portion has a fork structure with a pair of fork elements mechanically clamping and fixing the electrical mating contact element on the electrical contact device. The spring portion electrically connects the first and second contact portions. The spring portion permits an elastic variation of a spacing between the first and second electrical contact portions in the longitudinal direction.
