A female electrical contact including at least one axial elongate flexible spring offset from the axis (A) of the contact and elastically deformable in a transverse direction. The flexible spring (6) comprises a tail (5) engaged in a support (2, 4); a contact portion (7); an intermediate portion (8) located between the tail portion (5) and the front contact portion (7), and having longitudinal curvature of large radius without any folding so as to enable it to bend elastically in a transverse direction; and a portion (10) having a reduced moment of inertia located between the intermediate portion and the front contact portion, thereby making the spring suitable for distributing bending stresses over the entire length of the intermediate portion and facilitating progressive and continuous elastic bending thereof the three portions (5, 7, 8) and having predetermined transverse curvature imparting desired stiffness thereto; an abutment surface (2a) being located at the rear of the spring to keep its deformation within its elastic limits.

Flexible spring electrical contact for an electrical connector

The blade (12) is intended for a female contact for an electrical connector and arranged in order to extend into an elongate slot of a tubular socket of the contact by bearing against an external tube and by being engaged inside this socket and radially movable in an elastic fashion when a pin of an associated male contact is introduced into the socket. It comprises a central portion (13) bearing against the external tube, located between a tail end (7) and a contact end (9), which has a continuous longitudinal curvature of large radius and without folding so that the bearing surface. (T) of the blade against the external tube moves longitudinally when the contact end of the blade is stressed radially; two inertia-reducing zones (15, 16) capable of causing flexure of the blade and respectively located between the tail portion (7) and the bearing portion (13) and between the latter and the contact portion (9); and a predetermined transverse curvature in its contact and bearing portions so that the latter have a desired stiffness.

Female elastic-blade contact and blade for such a contact

A polygonal section connector comprises a male portion (1) and a female portion (9) that are suitable for coupling together, each supported by a respective support, with at least one of said portions being supported in floating manner. The female portion and/or the male portion is/are provided with alignment means (7, 16; 8, 17) for aligning the male portion in the female portion. One of the connector portions is fitted with centering means for centering it relative to the other portion, which means are suitable for prepositioning said portion, even when presented with an offset and/or an inclination relative to the other portion. The alignment means comprise prealignment means for prealigning the male portion in the female portion and including a skirt (12) which is polygonal in section and designed to receive the male portion as precentered by the centering means. The skirt (12) and the male portion (1) are provided with complementary reliefs (7, 16) for prealigning the male portion in the skirt (12).
