Contact-finger-element and tulip-contact-assembly for switching device

A tulip-contact-assembly comprising:

• a plurality of contact-finger-elements 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;
• a fingers-support-body comprising a circular cage-body configured for receiving resting-seats of said contact-finger-elements, guiding-housing-protrusions projecting from said circular cage-body according to a circumferential distribution so as to define a plurality of seat-slots each for a respective contact-finger-element, and an annular joint-rib through which is configured to be connectable to said second conducting-terminal, said annular joint-rib internally protruding from said circular cage-body and having a circular cross section configured for enabling a rotation-adjustment of said fingers-support-body relative to said second conducting-terminal for ensuring an alignment of said tulip-contact-assembly with said first conducting-terminal in an electrical-coupling position;
• and
• spring elements for urging said finger-contact-elements in a contact position against said first conducting-terminal and against said second conducting-terminal, said spring elements being configured for engaging with groove-seats obtained on said contact-finger-elements.
