Abstract
Abstract A connector element (1) comprises a dielectric sleeve (12) that axially accommodates a conductor (10), which may be female, and peripherally an outer conductor (16) including a rigid zone (160) followed by a nose (170), the solid beginning of which rests on a bearing surface (121) of the dielectric sleeve, while the subsequent slit portion of it terminates at an outer edge (180) provided with two chamfers connected by a flat side (183). This flat side assures electrical continuity, while the remainder of the nose (170) enables guidance and elastic retention in a homologous hole of the other connector, and the support surface (165) determines the coupling limit of the same connectors.
