Abstract:
An electric terminal (1) including a deformable portion (4) for connection to an electric cable (5); and a contact portion (2) presenting a first flexible contact blade (11) extending integrally from a front portion (12) of a wall (6) of the contact body (2) and bent rearwards towards the connecting portion (4), the first blade (11) cooperating elastically with a complementary contact element (3), and a second reinforcing blade (15) blanked in the same wall (6) of the contact body (2) and cooperating with the first blade (11) at least as of a predetermined degree of deformation of the first blade, for increasing the elastic load on the complementary contact element; the second blade (15) extending from the front portion (12) of the aforementioned wall of the contact body (2) towards the connecting portion (4) of the terminal (1); and the first (11) and second (15) blades cooperating mutually at the respective free ends (14, 16).
Abstract:
L'invention concerne un dispositif à contacts électriques (1) à déplacement d'isolant. Le contact (1) selon l'invention comprend deux lames dissymétriques (10, 11), l'une étant plus large que l'autre. Ces deux lames (10, 11) sant disposées dans deux rainures (200, 201) réalisées sur les parois des fentes (21) d'introduction du câble (3). La lame la plus large (10) est disposée dans une fente (201) formant un angle avec la direction (Δ') d'introduction du câble (3) et la lame la moins large (11) est disposée dans une rainure (200) formant un angle de 90° avec cette même direction (Δ'). Pour des câbles (3) de faible section, seule la lame la plus large (10) est sollicitée en flexion, pour des câbles (3) de plus forte section la lame la moins large (11) est repoussée dans son logement (200). Dans les deux cas, il y a réalisation d'un effet de coin et décalage des points de coupe.
