ABSTRACT:
A reinforcing fastener for fastening a chemical connector and an electronic circuit includes a substantially cylindrical section shaped element having edges defining an axial slit, wherein the element is formed of an alloy having both superelastic and shape memory properties. The slit is of such a size at a temperature below the Martensite transformation temperature of the alloy that the alloy is superelastically deformed when the slit is maintained at the same size while the alloy is above the Martensite transformation temperature. This results in the chemical connector being fastened to the electronic circuit with a substantially constant force over time.
