Title:
SHUNT RESISTANCE CURRENT SENSOR
Document Type and Number:
Japanese Patent JP2015021816
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a shunt resistance type current sensor capable of successfully securing a thermal connection relation between temperature detection means mounted on a circuit board and a bus bar.SOLUTION: A shunt resistance type current sensor 1 includes: a bas bar 10; a circuit board 20 arranged facing the bus bar 10; a connection terminal electrically connecting the bus bar 10 with the circuit board 20 and retaining the circuit board 20 at an interval for the bus bar 10; a voltage detection IC 30 mounted on the circuit board 20 and detecting a voltage value applied to the circuit board 20; and a temperature sensor 35 for detecting a temperature of the bus bar 10 so that the voltage detection IC 30 performs a correction. This bus bar 10 includes a concave part 13 projected toward the circuit board 20 at a position corresponding to the temperature sensor 35.
