Abstract

Il procedimento per la produzione di bobine del tipo comprendente un rocchetto (18) formato da due flange di estremità (16a, 16b) e da un nucleo centrale (20), ed un avvolgimento (28) elettricamente conduttivo avvolto intorno al nucleo (20), comprende le fasi di: inserire mediante rispettive propaggini (10) due lamine metalliche planari (12) in rispettive sedi (14) ricavate in una delle flange (16a), in modo tale per cui le estremità distali libere (22) delle lamine (12) si trovino all'esterno della porzione di spazio definita entro i piani individuati dalle due flange (16a, 16b); disporre l'avvolgimento elettrico (28) intorno al nucleo (20); connettere i capi (30) dell'avvolgimento (28) alle lamine (12); e piegare le estremità (22) delle lamine (12), in adiacenza della propaggine (10), entro la porzione di spazio definita dai piani individuati dalle due flange (16a, 16b), in modo tale per cui le estremità (22) fungono da terminali di connessione a spina lamellare dell'avvolgimento (28).The process for the production of coils of the type comprising a spool (18) formed by two end flanges (16a, 16b) and a central core (20), and an electrically conductive winding (28) wound around the core (20) , comprises the steps of: inserting two planar metal sheets (12) into respective seats (14) obtained in one of the flanges (16a) by means of respective offshoots (10), so that the free distal ends (22) of the sheets ( 12) are outside the portion of space defined within the planes identified by the two flanges (16a, 16b); arranging the electric winding (28) around the core (20); connecting the ends (30) of the winding (28) to the sheets (12); and folding the ends (22) of the sheets (12), adjacent to the offshoot (10), within the portion of space defined by the planes identified by the two flanges (16a, 16b), so that the ends (22) act from laminated pin connection terminals of the winding (28).
