SHUNT RESISTANCE TYPE CURRENT SENSOR

摘要

A shunt resistance type current sensor includes a bus bar that has an approximately flat plate shape, a circuit board that is installed to the bus bar, a pair of connecting terminal portions that electrically connects the circuit board to the bus bar, and a voltage detection unit that is mounted on the circuit board and detects a voltage value applied to the circuit board through the pair of connecting terminal portions so as to calculate a level of an electric current flowing through the bus bar. Each of the pair of connecting terminal portions extends from edge of the bus bar, and is erected toward the circuit board to penetrate the circuit board.

1. A shunt resistance type current sensor, comprising:
a bus bar that has an approximately flat plate shape; a circuit board that is installed to the bus bar; a pair of connecting terminal portions that electrically connects the circuit board to the bus bar; and a voltage detection unit that is mounted on the circuit board and detects a voltage value applied to the circuit board through the pair of connecting terminal portions so as to calculate a level of an electric current flowing through the bus bar, wherein each of the connecting terminal portions extends from edge of the bus bar, and is erected toward the circuit board to penetrate the circuit board, and wherein one of the connecting terminal portions extends in a direction which is different from a direction to which the other of the connecting terminal portions extends.
