Electrical interconnection device

A device for providing sufficient thermal energy to melt a fusible electrically conductive material and thereby provide electrically-conductive connections between a plurality of conductors of an electrical cable to corresponding opposed aligned contact pads on a surface of an electrical article, usable in conjunction with a source of constant amplitude high frequency alternating current of known frequency, said device comprising:

• an integral member formed from strip of a first metal having low electrical resistance and minimal magnetic permeability, said integral member defining a first layer having a carrier strip section and a plurality of fingers initially integrally coextending in a common direction along respective axis therefrom, each associated with and spaced to correspond with respective ones of said contact pads of said electrical article and having pad-proximate surfaces and opposed conductor-proximate surfaces;
• said carrier strip section having defined on a major surface thereof and integrally joined to said first layer thereof a second layer of a second metal having high electrical resistance and high magnetic permeability, said second layer having a thickness at least equal to one skin depth of said second metal, given said known frequency, said carrier strip section thereby defining a heater body;
• and
• said fingers being adapted to be disposed adjacent and between a corresponding contact pad of said electrical article and a respective conductor of said cable, each said finger including an end portion extending transversely in a manner intersecting a respective said axis, said end portion including a conductor-receiving aperture extending therethrough parallel to said respective axis, said finger having fusible electrically conductive material on said conductor-proximate and pad-proximate surfaces thereof, whereby upon disposing said conductors on said conductor-proximate surfaces of respective ones of said fingers and placing said fingers adjacent respective ones of said contact pads of said electrical article such that each said finger is disposed adjacent and physically between a corresponding conductor of said cable and a respective contact pad of said electrical article, such that upon said heater body being subjected to said constant current of known frequency, said heater body generates and transfers said sufficient thermal energy from said heater body to said finger to melt said fusible material disposed therealong thereby electrically and mechanically interconnecting said fingers to associated ones of both said corresponding and respective conductors and contact pads, whereafter said heater body is detachable from said fingers along said electrical article thereby electrically isolating the interconnections in which the fingers remain a permanent part of an electrically-conductive connection between the conductors of said cable and the contact pads of said electrical article.
