Electronic switching module for a power tool
First Claim
1. An electronic power apparatus comprising:
- a housing;
a pair of input power pins and a pair of output power pins mounted on a power circuit board;
a plurality of power components mounted on the power circuit board and electrically connected to the input power pins and the output power pins to modulate a supply of power from the input power pins to the output power pins; and
a control circuit arranged on a control circuit board disposed at a distance from the power circuit board, the control circuit board and the power circuit board being arranged inside the housing;
wherein the output power pins project through corresponding through-holes through the control circuit board to an outside part of the housing, the output power pins having at least one side protrusion arranged to spatially support the control circuit board with respect to the power circuit board inside the housing.

Abstract
An electronic power apparatus includes a housing, a pair of input power pins and a pair of output power pins mounted on a power circuit board, and power components mounted on the power circuit board and electrically connected to the input power pins and the output power pins to modulate a supply of power from the input power pins to the output power pins. A control unit of the electronic power apparatus is arranged on a control circuit board disposed at a distance from the power circuit board inside the housing. The output power pins project through corresponding through-holes through the control circuit board to an outside part of the housing, the output pins having at least one side protrusion arranged to spatially support the control circuit board with respect to the power circuit board inside the housing.
