Abstract
A current sensor includes an electrically conductive busbar with an upper side and a lower side. A cutout is formed adjacent to a tapering of the busbar. A carrier of a magnetic detection element is positioned relative to the cutout such that the magnetic detection element is positioned one of above the upper side or below the lower side of the busbar relative to the busbar.
Claims17
A current sensor comprising:
- an electrically conductive busbar having an upper side and a lower side, wherein a tapering is formed in the busbar and a cutout is formed in the busbar adjacent to the tapering;
- and a magnetic detection element is assigned to the busbar adjacent to the tapering;
- and a carrier supporting the magnetic detection element is positioned relative to the cutout in such a way that the magnetic detection element is positioned relative to the busbar one of above the upper side or below the lower side of the busbar;
- wherein the carrier is positioned along a Z coordinate direction in the cutout and is oriented perpendicular to the busbar;
- and
- wherein the magnetic detection element is aligned with at least a portion of the cutout in a Z coordinate direction;
- wherein the busbar is planar in a region of the cutout extending across the busbar at the tapering and including the cutout, and the magnetic detection element is spaced from the cutout in the busbar;
- and
- wherein, at the tapering, a cross-section of the busbar is reduced compared to an original cross-section.

A current sensor comprising:
- an electrically conductive busbar including:
- a first lateral edge and a second lateral edge spaced from each other, the first lateral edge including a first tapering extending towards the second lateral edge, and the second lateral edge including a second tapering extending towards the first lateral edge;
- an upper side and a lower side spaced from each other, the upper side and the lower side each extending from the first lateral edge to the second lateral edge;
- and a cutout extending through the upper side and the lower side, the cutout disposed between the first and second taperings, and the busbar being planar in a region of the cutout;
- a carrier;
- and
- a magnetic detection element supported by the carrier, wherein the carrier is positioned relative to the cutout such that the magnetic detection element is spaced from the upper side and the lower side of the busbar;
- wherein the carrier is positioned along a Z coordinate direction in the cutout and is oriented perpendicular to the busbar;
- wherein the magnetic detection element is aligned with at least a portion of the cutout in a Z coordinate direction;
- and
- wherein, between the first tapering and the second tapering, a cross-section of the busbar is reduced compared to an original cross-section.
