Abstract
The motor constituted, inter alia, by commutation means (40) with a connector (41) constituted by an insulating support (410) intended to be carried by the armature (30), and by conducting contactors (411) equipped with terminals (412) in order to receive the ends (321) of the wires (320) of the windings (32) of the armature (30) and with contacts (413) intended to make contact with each of the corresponding counter-contacts (413') of a printed circuit (421) is characterized in that the insulating support (410) carries at its periphery (4101) a median ring (4102) edged on either side with lateral borders (4103) of lesser diameter, and in that this ring (4102) is caused to form teeth (4104) whose profile (4106), at least close to the bottom (4107) of each space width (4108) which separates them, exhibits a recessed portion (4105), in that each border (4103) is provided with notches (4109) disposed in vertical line with the teeth (4104), in that the terminals (412) and the contacts (413) are joined together by central rungs (415) with two wings (416) which are each intended to be engaged into the space widths (4107) in such a manner that each wing (416) can be applied against a reces…
