A transformer includes a bobbin. The bobbin includes a main body, a connection member, and a terminal base. The main body is wound by a coil. Two sides of the connection member are respectively connected to the main body and the terminal base. A plurality of connection terminals of the coil extend to the terminal base through a wire trough of the main body and are connected to pins of the terminal base. The connection member is cut off by automated machining, and the terminal base is mounted on a surface of a housing of the transformer, and no pin is disposed on the housing. Hence, the overall size of the transformer is effectively reduced.

A coil device includes a coil portion and a bobbin. The coil portion includes wires connectable to terminals. The bobbin includes a first terminal block and a second terminal block formed on both sides in a winding axis direction of a cylindrical portion for forming the coil portion around the cylindrical portion. A length of the first terminal block in a width direction perpendicular to the winding axis direction is larger than that of the second terminal block in the width direction.

least one contact element is covered at least in part by a first wall section of the cover cap. The coil body comprises a depression which is formed below the magnetic core and in which a second wall section of the cover cap extending perpendicularly to the side surface of the magnetic core extends between the coil body and the magnetic core received in the coil body. The cover cap comprises a third wall section which is disposed opposite the second wall section and covers at least in part a side surface of the magnetic core and covers the winding at least in part.

A component having a winding carrier, at least one winding, a magnetic core and first and second connections. The winding carrier surrounds at least regions of the core in such a way that an insulation section between the connections along an underside of the component cannot be bypassed via the core. In particular, an underside of the winding carrier is designed to be closed.

Provided are a coil device that considerably reduces the man-hours and the cost for manufacturing, and a motor-driven valve and a solenoid valve including such a coil device. The terminal end of the magnet wire is fixed to a conducting terminal by swaging and/or fusing at a distal-end binding part for binding the terminal end of the magnet wire.

An inductive component comprises a magnetic core, a winding, and a coil body. The coil body comprises a contact element attached to a contact strip of the coil body for electrical connection to the winding, a magnetic core receptacle in which the magnetic core is received in part, and an elongate recess formed in the contact strip and extending only in part below the magnetic core and above the contact element and extending in a longitudinally direction of the contact strip. A cover cap is attached to the contact strip and covers at least in part a side surface of the magnetic core facing the contact element. The cover cap comprises a first wall section covering at least in part the side surface of the magnetic core facing the contact element. A second wall section of the cover cap extending perpendicular to the first side surface of the magnetic core is inserted into the recess formed in the coil body, where the second wall section extends between the magnetic core and the contact element in the coil body.

Present disclosure relates to a transformer structure. The transformer structure includes a first inductor and a second inductor. The first inductor has first turns and second turns. The second inductor has third turns and fourth turns. The first turns of the first inductor and the third turns of the second inductor are mutually disposed in a first area of a first metal layer. The second turns of the first inductor and the fourth turns of the second inductor are mutually disposed in a second area of the first metal layer. The first area is adjacent to the second area.

A thin resonant transformer includes a wire bobbin having a spool, an inner winding wound around the spool, a magnetic plate mounted in the wire bobbin, an outer winding wound in the wire bobbin and encompassing the inner winding and the magnetic plate, and two symmetric magnetic cores mounted on the wire bobbin. The wire bobbin has a top provided with a top plate and a bottom provided with a bottom plate. The magnetic plate is arranged between the inner winding and the outer winding. The inner winding, the outer winding, and the two magnetic cores generate a first magnetic circuit. The magnetic plate, the inner winding, and the outer winding generate a second magnetic circuit.

In an embodiment, an inductive component includes at least one electrical conductor, a coil former with a hollow-shaped winding former, on a surface of which the at least one electrical conductor is wound around the winding former, a magnetic core arranged in a first cavity of the winding former and a potting material, wherein the at least one electrical conductor is surrounded by the potting material, wherein the potting material has no directly adherent contact with the magnetic core, wherein the magnetic core comprises a first part-body and a second part-body, which are connected to one another, wherein at least one of the first part-body or the second part-body of the magnetic core comprises a leg arranged in the first cavity of the winding former and at least one further leg arranged outside the first cavity of the winding former.

A magnetic connector assembly has two independent magnetic components sharing a common core structure. The magnetic assembly includes first and second bobbins, and includes a magnetic core. The magnetic core includes first and second core halves, each half including a main core body, a first outer leg, a second outer leg, and a middle leg. The first outer leg fits within a passageway of the first bobbin. The second outer leg fits within a passageway of the second bobbin. The middle leg fits between the two bobbins.
