Abstract

L'invention porte sur une bobine de relais électromagnétique présentant: un élément magnétoconducteur en C; un enroulement isolé; la bobine proprement dite; et une paire de broches conductrices intégrés à la bobine depuis lesquelles l'enroulement est enroulé autour de la bobine. Chacune des broches conductrices présente deux extrémités libres dont l'une en tire-bouchons est connectée à l'enroulement du relais et l'autre sert de spire de tête à l'enroulement. En formant une telle broche et en la moulant avec la bobine, on élimine l'opération de soudure d'un plot conducteur à l'extrémité en tire-bouchon, au moyen d'un équipement supplémentaire. Cela permet: d'économiser sur l'équipement; d'éliminer le problème du joint de résine; de simplifier l'opération; d'accroître le rendement magnétique de l'enroulement; de simplifier l'opération de bobinage; de miniaturiser le relais; de réduire les coûts en matériaux; et d'accroître notablement la fiabilité, le rendement et la qualité du relais.
