ABSTRACT:
A contact element of an electrical connector includes two spring contact members bifurcated from an intermediate pivot portion which is secured to a basic pivot portion by a pendulum arm member, in which an inner spring contact member is formed with a plurality of deflective spring bow portions interpolatively wound within a contour of an outer spring contact member which is formed with a plurality of deflective spring bow portions extrapolatively disposed around the inner spring contact member to prolong a force arm of each spring contact member to increase an elastic clamping force of the contact element in order for firmly clamping a printed circuit board between the two spring contact members for an efficient electrical connection of the printed circuit board.
