Abstract:
A contact-finger-element includes a first contact-portion and a second-contact-portion which are suitable for engaging with a first conducting terminal and with a second conducting-terminal respectively; the first-contact-portion and the second-contact-portion have respective cross-sections including concave “V”-shaped profiles, each concave “V”-shaped profile having two straight portions mutually tilted by a respective included angle which is adapted so as to enable the first contact-portion and the second-contact-portion to tangentially contact with a curved surface of the first conducting terminal and of the second conducting terminal respectively at intermediate zones of the respective straight portions. There is also disclosed a tulip-contact assembly comprising a plurality of such contact-finger-elements.
