Abstract

L'invention concerne un dispositif formant électroaimant (3), comprenant : une carcasse d'enroulement (32) constituée d'une résine ; une bobine (33) formée sur la carcasse d'enroulement ; et une paire de bornes côté bobine (34) dont des parties supérieures (341) sont reliées à la bobine. Les parties supérieures des bornes côté bobine sont enfoncées dans des rainures de fixation (323) ménagées dans une partie bride (322) de la carcasse d'enroulement et fixées à la partie bride, des parties inférieures (342) faisant elles saillie vers le bas depuis la partie bride. Il est possible d'utiliser pour les bornes côté bobine aussi bien des bornes enfichables dotées de parties inférieures du type lamelle que des bornes sur substrat dotées de parties inférieures en forme de broche, les bornes enfichables et les bornes sur substrat possédant la même forme au niveau des parties enfoncées dans les rainures de fixation. Il est donc possible de normaliser la carcasse d'enroulement et de réduire le coût de fabrication du dispositif formant électroaimant. Les parties inférieures des bornes enfichables comportent un trou traversant (346) ménagé près de la base de la partie bride, ce trou traversant permettant de coller solidement le dispositif formant électroaimant doté des bornes enfichables sur un élément prédéfini.
