ABSTRACT:
A progressively-increasing clamping force lead (10) includes a resilient contact finger (22) having an outer arcuate loop portion (26) and a locking tab (34) having a camming surface (70) projecting at an angle from an outer end of the arcuate loop portion toward a planar surface (56) of a clamping finger (20). In the assembling of the lead (10) to the substrate circuit device (16), as the locking tab (34) engages and rides up an adjacent edge (64) of the substrate circuit device, the locking tab causes progresive flexing of an inner connecting portion (36) of the contact finger (22) and progressive coiling of the arcuate loop portion (26) of the contact finger to cause the arcuate loop portion to engage a contact pad (14) with a progressively-increasing force. Subsequently, the arcuate loop portion (26) and the locking tab (34) seat firmly on the contact pad (14) to retain the lead (10) securely on the substrate circuit device (16). The lead (10) then may be soldered to the contact pad (14).
