A compact coil assembly (10) is provided for protecting electrical components from transient voltage surges. The assembly (10) includes a bobbin (12) having a cylindrical core (14) with two ends. A first and second flange (20, 22) are each perpendicularly mounted and extended outwardly from one of the ends. A lead pin (30) is perpendicularly upstanding on the top surface of the first flange (20). The first flange (20) has parallel outer and inner walls (26, 28) defining a channel (24) therebetween. The inner wall (28) has a slot (32) therethrough. The slot (32) is positioned on the top surface (34) of the first flange opposite the lead pin (30). The channel (24) extends from the lead pin across to the end of the slot (32) near the core (14). The width of the channel (24) and the slot are adapted for guiding a winding wire therethrough.

L'invention concerne un ensemble bobine compact (10) servant à protéger des composants électriques contre des surtensions transitoires. L'ensemble (10) comporte une bobine (12) possédant un noyau cylindrique (14) pourvu de deux extrémités. Une première et une deuxième bride (20, 22) sont montées chacune perpendiculaire et s'étendent vers l'extérieur depuis une des extrémités. Une broche conductrice (30) est située verticale perpendiculairement à la surface supérieure de la première bride (20). La première bride (20) possède des parois parallèles intérieure et extérieure (26, 28) définissant un passage (24) entre elles. La paroi intérieure (28) est pourvue d'une fente (32) qui la traverse. La fente (32) est placée sur la surface supérieure (34) de la première bride à l'opposé de la broche conductrice (30). Le passage (24) s'étend depuis la broche conductrice jusqu'à l'extrémité de la fente (32) à proximité du noyau (14). La largeur du passage (24) et la fente sont conçues pour guider un fil d'enroulement.
