ABSTRACT:
The invention is a male contact element for low-insertion-force electrical connector of the type having a cylindrical pin portion prolonged at its extremity by a tapered portion terminating in a nose of constant-radius generatrices. The tapered portion has a length L such that 1.80d.ltoreq.L.ltoreq.1.96d, d being the nominal diameter of the cylindrical portion of the male contact element, and has a first ogival surface of revolution about the longitudinal axis of the contact with generatrices of constant radius, R such as 6.4d.ltoreq.R.ltoreq.7.9d, the first ogival surface connecting tangentially to the cylindrical portion, and a second ogival surface of revolution about the longitudinal axis of the contact constituting the nose of the contact of generatrices of constant radius r, having a value of 0.42d.ltoreq.r.ltoreq.0.52d, the first and second ogival surfaces connecting tangentially.
