Abstract
A high-current element for high-current printed circuit boards is formed from at least two metal sheets which are connected to form a sheet-metal stack and which have a plurality of pins at least at an end region thereof, and wherein the sheet-metal stack has a terminal region, a pin region, and a connection region, and wherein the metal sheets are connected to one another in the connection region, and the pins are arranged in the pin region and formed for contacting with the high-current printed circuit board, and the terminal region is set up to be used as a terminal region for connecting the high-current element to external power terminals.
Claims17
A high-current element for high-current printed circuit boards, comprising:
- at least two metal sheets which are connected to form a sheet-metal stack and which have a plurality of pins at least at an end region thereof,
- wherein the sheet-metal stack has a terminal region, a pin region, and a connection region,
- wherein the metal sheets are connected to one another in the connection region, and the pins are arranged in the pin region and formed for contacting with the high-current printed circuit board, and the terminal region is configured to be used as a terminal region for connecting the high-current element to external power terminals, and
- wherein one of:
- the connection region merges into the terminal region in a bent manner, or
- at least one metal sheet of the connection region merges into the terminal region in a bend, and the other metal sheets end before the bend.
A method for producing and assembling a high-current element, comprising:
- separating metal sheets from a sheet-metal blank in a single-step or multi-step process;
- reshaping the metal sheets into a predetermined basic shape;
- stacking the metal sheets to form a sheet-metal stack;
- joining the sheet-metal stack by a joining process in a connection region thereof;
- coating the sheet-metal stack partially or completely;
- and
- connecting the high-current element initially by connecting the pins at the pin region to the high-current printed circuit board and/or connecting external power terminals at a terminal region of the high-current element.
A high-current element for high-current printed circuit boards, comprising:
- at least two metal sheets which are connected to form a sheet-metal stack and which have a plurality of pins at least at an end region thereof,
- wherein the sheet-metal stack has a terminal region, a pin region, and a connection region,
- wherein the metal sheets are connected to one another in the connection region, and the pins are arranged in the pin region and formed for contacting with the high-current printed circuit board, and the terminal region is configured to be used as a terminal region for connecting the high-current element to external power terminals, and
- wherein either one or more intermediate layers are arranged between the metal sheets of the sheet-metal stack.
