Abstract
In a contact base with a plurality of contact springs for making contact with electronic components, in particular ICs, the contact springs each have an elongate contact blade, the longitudinal center plane of said contact blade being situated parallel to the bending plane of the spring arm of the contact spring. Furthermore, the spring arm is formed in such a way that, when a pin is pressed, the contact blade moves in a direction which differs from the feed direction of the component in such a way that the contact blade moves along the pin.
Claims16
A contact spring for contacting electronic components, particularly integrated circuits, wherein the contact spring comprises an elongate spring arm a free end of which comprises an elongate contact blade, on which a pin of a component may be placed, wherein the spring arm is displaceable in a predefined bending plane by movement of the component in a feed direction, wherein the longitudinal centre plane of the contact blade is arranged at an angle of at most +/−30°, particularly parallel, to the bending plane of the spring arm, wherein the spring arm is constructed in such manner that, when the pin is pressed on, the contact blade moves in a direction which differs from the feed direction of the component in such a way that the elongate contact blade shifts along the pin and wherein the elongate contact blade is convex for at least a part of its length, wherein the contact blade is curved in an arch over its length, and wherein a width of the contact blade is narrower in a middle area than in end areas.
