Claim:
1. Contact-finger-element comprising: a first contact-portion and a second-contact-portion which are configured for engaging with a first conducting terminal and with a second conducting-terminal respectively, wherein said first-contact-portion and said second-contact-portion have respective cross-sections including concave “V”-shaped profiles, each concave “V”-shaped profile being composed of two straight portions mutually tilted by a respective included angle which is selected to enable said first contact-portion and said second-contact-portion to tangentially contact with a curved surface of said first conducting terminal and of said second conducting terminal respectively at intermediate zones of the respective straight portions; wherein said first contact-portion is obtained at a first end of a body extending along a longitudinal axis and has a first “V”-shaped groove delimited by two mutually incident first contact-surfaces configured for tangentially contacting with the curved surface of said first conducting terminal, and wherein said second contact-portion is obtained at a second end of said body and has a second “V”-shaped groove delimited by two mutually incident second contact-surfaces configured for tangentially contacting with the curved surface of said second conducting-terminal; and wherein said first contact-surfaces comprise first conical-contact-surfaces which are convex and symmetrically arranged with respect to a longitudinal plane of said body, and wherein said second contact-surfaces comprise second conical-contact-surfaces which are convex and symmetrically arranged with respect to said longitudinal plane.
