Abstract

La présence invention concerne des perfectionnements apportés à la construction des noyaux magnétiques articulés et fexibles. Ce noyau est caractérisé en ce qu'il est constitué d'une multiplicité de plaquettes métalliques, de forme sensiblement rectangulaire, toutes ces plaquettes étant semblables et articulées entre elles, chaque plaquette présentant un petit côté en forme d'arc saillant et le petit coté opposé en forme d'arc rentrant servant d'accouplement pour l'arc saillant de la plaquette contiguë, en ce que ces plaquettes sont articulées entre elles en étant pourvues à cet effet de rivets de liaison et d'articulation qui traversent les trous des plaquettes, en ce que les parties métalliques sont isolées au moyen d'un fourreau en matériau diélectrique isolant et flexible et en ce que les extrémités du noyau magnétique sont reliées par suite de l'accouplement des extrémités de toutes les têtes des plaquettes adjacentes constituant l'épaisseur du noyau.The present invention relates to improvements made to the construction of articulated and flexible magnetic cores. This core is characterized in that it consists of a multiplicity of metal plates, of substantially rectangular shape, all of these plates being similar and articulated to each other, each plate having a small side in the form of a protruding arc and the small side. opposite in the form of a re-entrant arc serving as a coupling for the protruding arc of the contiguous plate, in that these plates are articulated to each other by being provided for this purpose with connecting and articulation rivets which pass through the holes of the plates , in that the metal parts are insulated by means of a sheath of insulating and flexible dielectric material and in that the ends of the magnetic core are connected as a result of the coupling of the ends of all the heads of the adjacent plates constituting the core thickness.
