Abstract
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.
Claims18
A device comprising:
- a winding carrier;
- at least one winding of a wire arranged around the winding carrier;
- a magnetic core;
- at least one first electrical terminal;
- and
- at least one second electrical terminal;
- wherein the winding carrier encloses the magnetic core at least in regions such that an insulation path between the at least one first electrical terminal and the at least one second electrical terminal along a lower side of the device does not comprise a bridging by the magnetic core,
- wherein the winding carrier is formed as a single piece and has a lead-through, the magnetic core being arranged in the lead-through, and
- wherein the winding carrier further comprises a first opening at a side face for inserting a first core part and a second opening at an upper side for inserting a second core part, the lead-through being accessible from outside of the device only through the first opening and the second opening.

A method for manufacturing a device, comprising the steps of:
- providing a winding carrier that is formed as a single piece and has a lead-through, wherein the winding carrier further comprises a first opening at a side face for inserting a first core part and a second opening at an upper side for inserting a second core part, and wherein the lead-through is accessible from outside of the device only through the first opening and the second opening;
- inserting the first core part into the first opening;
- and
- inserting the second core part into the second opening.
1 more element
A device comprising:
- a winding carrier;
- and
- at least one winding of a wire arranged around the winding carrier;
- a magnetic core;
- at least one first electrical terminal;
- and
- at least one second electrical terminal;
- wherein the winding carrier comprises a lower side, the at least one first electrical terminal and the at least one second electrical terminal arranged opposite to each other with respect to the lower side, the winding carrier lacking a cutout through which the core is exposed at least in a region of the lower side which is laterally bounded by the at least one first electrical terminal and the at least one second electrical terminal,
- wherein the winding carrier is formed as a single piece and has a lead-through, the magnetic core being arranged in the lead-through, and
- wherein the winding carrier further comprises a first opening at a side face for inserting a first core part and a second opening at an upper side for inserting a second core part, the lead-through being accessible from outside of the device only through the first opening and the second opening.
7 more elements
A device comprising:
- a winding carrier formed as a single piece, the winding carrier having two side faces opposite each other, an upper side, a first opening and a second opening;
- at least one winding of a wire arranged around the winding carrier;
- a magnetic core having a first core part and a second core part;
- at least one first electrical terminal;
- and
- at least one second electrical terminal;
- wherein the winding carrier encloses the magnetic core at least in regions such that an insulation path between the at least one first electrical terminal and the at least one second electrical terminal along a lower side of the device does not comprise a bridging by the magnetic core,
- wherein the first opening is arranged at a first one of the two side faces for inserting the first core part in the winding carrier, the second opening is arranged at the upper side for inserting the second core part in the winding carrier, and
- wherein the magnetic core is completely or in a predominant part encased by the winding carrier at a second one of the two side faces.
