Patent attributes
A shunt resistor module, which includes a shunt resistor having a resistor unit having a predetermined resistance, plate-shaped terminal units respectively configured to extend at both sides of the resistor unit, and a voltage measurement lead pin configured to protrude perpendicular to the terminal unit and having an end portion bent to be parallel to the terminal unit, and a PCB substrate having an assembly guide portion formed to be cut inward by a predetermined depth from an outermost side thereof. The voltage measurement lead pin is fit into the assembly guide portion so that the resistor unit and the terminal unit are placed on a front surface of the PCB substrate and the end portion of the voltage measurement lead pin is caught at a rear surface of the PCB substrate.
