Abstract

L'invention concerne un ensemble connecteur (10) pour le montage d'un instrument (I) sur un élément moteur(11) à broches de connexion espacées (31, 32). Ledit ensemble comprend une paire de plaques espacées (26), portant chacune un premier récepteur (21) qui reçoit une première (31) de ces broches et un second récepteur (22) qui reçoit la seconde (32) de ces broches, sachant qu'au moins l'un (22) des deux récepteurs est un récepteur réglable qui tourne autour d'un axe et qui présente un trou transversal (57), espacé radialement (R) de l'axe (X) et tournant autour de lui. La rotation du récepteur réglable (22) autour de l'axe modifie l'espacement relatif (50) entre les deux récepteurs.
