Patent ID: 7214107

Claim:
A low-cost simplified electrical connector adapted for use with biomedical patch-type electrodes having at least one button-shaped terminal, comprising: a unitary substantially metallic spring element having: first and second substantially opposing bias portions; first and second connecting portions coupled to respective ones of said first and second opposing portions; a variable geometry portion coupled to both said connecting portions and comprising a variable size aperture and a fulcrum portion, said aperture being configured to receive one of said button-shaped terminals when properly expanded; and a housing element having first and second movable actuation elements, said movable actuation communicating with respective ones of said opposing portions; wherein upon biasing at least one of said first and second movable actuation elements, said aperture expands in size; and wherein upon unbiasing said at least one movable actuation elements, said aperture contracts in size due at least in part to spring force generated by said fulcrum portion.
