Patent ID: 8317552

Claim:
A female electrical contact ( 100 ) with a general cylindrical circular shape that comprises two connecting ends ( 102 , 103 ), at least one first connecting end having at least two longitudinal slots, with said first connecting end being able to have two states, respectively a non-stressed state, in which said first connecting end has a straight, longitudinal cross-section, and a stressed state, in which said first connecting end has a tapered longitudinal cross-section, with an annular groove ( 107 ) being hollowed out from an outside surface ( 106 ) of the wall ( 105 ) of the female electrical contact, at the first connecting end, designed to receive a tightening element ( 108 ), characterized in that the annular groove has, when the first connecting end is in the non-stressed state, a tapered longitudinal cross-section such that the diameter of a front end of the annular groove is larger than the diameter of a rear end of said annular groove, and in that the annular groove has, when the first connecting end is in the stressed state, a straight cross-section; and wherein the annular groove has—in the non-stressed state of the first connecting end—a slope that has an angle (X 1 ) relative to a longitudinal axis (A′) of the female electrical contact that is essentially equal to a tightening angle (X 2 ) that has to be applied to the first connecting end to shift to the stressed state and to obtain a reduced connecting diameter (D″).
