Contact pin for an electrical connector with a weak insertion force.

摘要

The invention relates to a male contact element for an electrical connector to low insertion force of the type comprising a part of a cylindrical pin is extended at its end by a tapered part terminated by a nose to the generatrices of a constant radius. / p & & p & the tapered part 2, 3 has a length l, such as 1,80d = l = 1,96d, d being the nominal diameter of the cylindrical portion 1 of the male contact element, and has a first cone-shaped surface 2 of revolution about the longitudinal axis of the contact generatrices, to a constant radius r, such as 6,4d = r = 7,9d, the first cone-shaped surface 2 is connected tangentially to the cylindrical portion 1, and a second cone-shaped surface 3 of revolution about the longitudinal axis of the contact, constituting the nose of the contact, to the generatrices of a constant radius r, such as 0,42d = r = 0,52d, said first and second surfaces 17 2, 3 are joined tangentially t / p
