Abstract
An electrical connector includes connector pads on a printed circuit board and contact members on an insulating substrate. The contact members are pressed against the contact pads by a compression mat having compressor fingers. A clamping arrangement forces the compressor fingers against the substrate and thereby presses the contact members against the contact pads. To counteract the inherent tendency of the compressor fingers to undergo stress relaxation after the compressor mat has been clamped, the connector also includes filler members disposed at least partially within the compressor fingers, essentially a “button-within-a-button” arrangement. Optionally, a filler deflection member may be interposed between the compression mat and a clamping plate of the clamping arrangement so that the filler deflection member abuts against the filler members. Alternatively, the filler members may be integral features of the deflection member.
