The invention relates to a transformer (10, 10′) with a core (11) which has a center piece (11a) with a first and a second flange (11b, 11c), in which a first and a second winding (12, 13) of the transformer (10, 10′) are wound on the center piece (11a). To produce a transformer as compact as possible which allows simple adaptation to limit leakage currents, it is proposed that the winding end pieces (12a, 12b) of the first winding (12) guided out of the winding body are guided through at least one recess in the first flange (11b) and that winding end pieces (15a, 15b) of the second winding (13) guided out of the winding body are provided which form at least partly loose line ends. Alternatively, the winding end pieces (12a, 12b) of the first winding (12) guided out of the winding body are guided immediately about the edge of the first flange (11b) and connected with connecting elements (14a, 14b) which are arranged on the side of the first flange (11b) opposite the center piece (11a).
A transformer (10, 10′) with a core (11) which has a center piece (11a) with a first and a second flange (11b, 11c), in which a first and second winding (12, 13) of the transformer (10, 10′) are wound on the center piece (11a), in which the winding end pieces (12a, 12b) of the first winding (12) guided out of the winding body are guided through at least one recess in the first flange (11b) and upon exiting said at least one recess in the first flange (11b), the winding end pieces (12a, 12b) being further guided through at least one bore of a circuit board upon which said transformer (10, 10′) is supported, and in which winding end pieces (15a, 15b) of the second winding (13) guided out of the winding body are provided which form at least partly loose line ends.
A transformer (10″) with a core (11) which has a center piece (11a) with a first and a second flange (11b, 11c) on the two ends of the center piece (11a), in which a first and a second winding (12, 13) of the transformer (10″) are wound on the center piece (11a), in which the winding end pieces (12a, 12b) of the first winding (12) guided out of the winding body are guided directly around the edge of the first flange (11b) and connected with connecting elements (14a, 14b) which are arranged on the side of the first flange (11b) opposite the center piece (11a), and in which winding end pieces (15a, 15b) of the second winding (13) guided out of the winding body are provided which form at least partly loose line ends.
A circuit board with a transformer (10″) with a core (11) that has a center piece (11a) with a first and a second flange (11b, 11c) on the two ends of the center piece (11a), in which a first and a second winding (12, 13) of the transformer (10″) are wound on the center piece (11a), in which the winding end pieces (12a, 12b) of the first winding (12) guided out of the winding body are guided directly around the edge of the first flange (11b) and connected with connecting elements (14a, 14b) which are arranged on the side of the first flange (11b) opposite the center piece (11a), the winding end pieces (12a, 12b) of the first winding (12) being connected with connecting pins (14a, 14b) placed on the side of the first flange (11b) opposite the center piece (11a), and in which winding end pieces (15a, 15b) of the second winding (13) guided out of the winding body are provided which form at least partly loose line ends and which are connected directly with contact points (19, 20) on the circuit board (16).
A transformer (10, 10′) with a core (11) which has a center piece (11a) with a first and a second flange (11b, 15c), in which a first and second winding (12, 13) of the transformer (10, 10′) are wound on the center piece (11a), in which the end pieces (12a, 12b) of the first winding (12) guided out of the winding body are guided through at least one recess in the first flange (11b), the winding end pieces (12a, 12b) of the first winding (12) being connected with connecting pins (14a, 14b) placed on the first flange (11b), and in which winding end pieces (15a, 15b) of the second winding (13) guided out of the winding body are provided which form at least partly loose line ends.
A transformer (10″) with a core (11) which has a center piece (11a) with a first and a second flange (11b, 11c) on the two ends of the center piece (11a), in which a first and second winding (12, 13) of the transformer (10″) are wound on the center piece (11a), in which the winding end pieces (12a, 12b) of the winding (12) guided out of the winding body are guided directly around the edge of the first flange (11b) and connected with connecting elements (14a, 14b) which are arranged on the side of the first flange (11b) opposite the center piece (11a), the winding end pieces (12a, 12b) of the first winding (12) being connected with connecting pins (14a, 14b) placed on the side of the first flange (11b) opposite the center piece (11a), and in which winding end pieces (15a, 15b) of the second winding (13) guided out of the winding body are provided which form at least partly loose line ends.
A circuit board (16) with a transformer (10, 10′) with a core (11) which has a center piece (11a) with a first and a second flange (11b, 11c), in which a first and a second winding (12, 13) of the transformer (10, 10′) are wound on the center piece (11a), in which the winding end pieces (12a, 12b) of the first winding (12) guided out of the winding body are guided through at least one recess in the first flange (11b), and upon exiting said at least one recess in the first flange (11b), the winding end pieces (12a, 12b) being further guided through at least one bore of said circuit board, and in which winding end pieces (15a, 15b) of the second winding (13) guided out of the winding body are provided which form at least partly loose line ends and which are connected directly with contact points (19, 20) on the circuit board (16).
