Abstract

Selon un mode de réalisation, la présente invention concerne un dispositif connecteur dans lequel les positions de rotation relatives de deux connecteurs autour d'un axe s'étendant dans la direction de connexion des deux connecteurs peuvent être accrues, lesdites positions étant des positions de rotation dans lesquelles les deux connecteurs peuvent se connecter l'un à l'autre. Un premier connecteur 21 comprend une première borne de référence 61, deux premières bornes 62a, 62b et un élément de court-circuitage côté premier connecteur 81 par lequel les premières bornes 62a, 62b sont court-circuitées l'une à l'autre. Un second connecteur 22 comprend une seconde borne de référence 131 et des secondes bornes 132a, 132b, le nombre desdites secondes bornes 132a, 132b étant égal ou inférieur au nombre de premières bornes 62a, 62b. Vues dans une direction de connexion Z1 du premier connecteur 21 et du second connecteur 22, les premières bornes 62a, 62b sont disposées de manière à présenter une symétrie de rotation autour de la première borne de référence 61. Les secondes bornes 132a, 132b peuvent respectivement faire face à l'une ou l'autre des premières bornes 62a, 62b dans la direction de connexion Z1 quand la seconde borne de référence 131 fait face à la première borne de référence 61 dans la direction de connexion Z1.
