摘要： A temperature sensor (60) is placed positionally corresponding to a central portion of a shunt resistor portion (SR). According to the configuration, it is possible to detect an approximately average temperature of the shunt resistor portion (SR) while avoiding a temperature biased in the temperature distribution in the shunt resistor portion (SR). As a result, the temperature of the shunt resistor portion which is the base of the resistance is reliably detected to enable the accuracy of current detection to be improved.

摘要： A shunt resistance type current sensor includes a bus bar, a circuit board, voltage detection terminals and a voltage detector for detecting a magnitude of voltage applied to the bus bar. The bus bar is constituted of a through hole to be connected to a battery post, a through hole to be connected to a stud bolt for fixing a wire harness, and a shunt resistance part located between the through hole for the battery post and the through hole for the wire harness. The bus bar is configured so that an area including the through hole and an area including the through hole are formed in a stepped manner via a bent part.

摘要： A shunt resistance type current sensor includes a bus bar, a circuit board disposed above the bus bar, a pair of connection terminals that electrically connect between the circuit board and the bus bar, and a voltage detector that detects a value of voltage applied to the circuit board via the pair of connection terminals in order to detect a value of current flowing through the bus bar. The circuit board includes a pair of circuit patterns and a pair of voltage detection lands for electrically connecting between the pair of circuit patterns and the connection terminals. The pair of voltage detection lands and the voltage detector are disposed separately to each other to a degree that thermal influence on the pair of voltage detection lands due to heat generated by the voltage detector can be suppressed.

摘要： A shunt type current sensor (1) using an infrared ray temperature detection unit as a temperature sensor (60) can detect the temperature of a shunt resistance portion (SR) directly through the detection of infrared rays radiated from the shunt resistance portion (SR). Such a detection method is not so much affected by thermal loss, as compared with a method for detecting a temperature in a course of sequential heat conduction via a bus bar (10) and a circuit board (20). It is therefore possible to suppress a gap between the temperature of the shunt resistance portion (SR) and the detected temperature.

摘要： A shunt resistance-type current sensor is provided, in which a voltage detection terminal electrically connects a busbar and a circuit board. The voltage detection terminal may include a first extension piece that extends from a side edge of the busbar away from the circuit board. The voltage detection terminal may include a second extension piece that extends from the first extension piece in a direction toward the circuit board. The circuit board may be electrically connected to the busbar via a connection portion extending from the second extension piece. In one example, the connection portion may extend through the circuit board. Additionally, an intermediate portion may be disposed between and connect the first extension piece and the second extension piece such that a surface of the intermediate portion faces a surface of the circuit board.
