Patent ID: 7229321

Claim:
In combination with a circuit part having a pair of opposite faces terminating at respective edges, an electrical contact comprising: a pair of arms extending generally parallel to and spaced apart transversely of an inward insertion direction, each having an outer end and an inner end, and defining a slot open outwardly against the insertion direction, each arm outer end having an end face extending at an acute outer angle to the direction, the end faces diverging outward from each other against the direction; a bight interconnecting the arm ends, the arms being limitedly elastically deformable for elastic displacement of the arm outer ends perpendicular to the direction; an inner contact bump projecting on each arm between the respective end face and the bight transversely of the direction into the slot, the inner bump being spaced apart tranverse to the direction by a predetermined inner spacing equal to less than a transverse distance between the circuit-part faces such that when the part is pressed in the insertion direction against the end faces its edges engage the end faces and elastically spread the arm outer ends while the end faces round the edges, the inner bumps each having a flat outer flank forming to the direction an inner angle smaller than the outer angle formed between the end faces; and an outer bump projecting on each arm from between the respective inner bump and the respective end face transversely of the direction into the slot, the outer bumps being spaced apart transverse to the direction by a predetermined outer spacing equal at most to the inner spacing.
