RELAY BUSBAR DEVICE WITH BUILT-IN CURRENT SENSOR FOR VEHICLE
First Claim
1. A relay busbar device with a built-in current sensor, which is interposed between a motor casing and an inverter casing, comprising:
- a relay busbar, both ends of which enter into both of the casings;
a resin plate, through which the relay busbar penetrates, and which is interposed between the two casings;
a magnetic core, positioned within the resin plate and surrounding the relay busbar; and
a magnetic sensor, provided in a removed portion of the magnetic core,wherein the relay busbar is mold-formed integrally with the resin plate during resin molding thereof, and incorporates therein a current sensor in which a change in magnetic field occurring in the removed portion due to current flowing in the relay busbar is detected by the magnetic sensor and a value of the current flowing in the relay busbar is measured.

Abstract
A relay busbar device of one embodiment is a relay busbar device with a built-in current sensor, which is interposed between a motor casing and an inverter casing, and includes a relay busbar both ends of which enter into both of the casings; a resin plate, through which the relay busbar penetrates, and which is interposed between the two casings; a magnetic core, positioned within the resin plate and surrounding the relay busbar; and a magnetic sensor provided in a removed portion of the magnetic core. The relay busbar is mold-formed integrally with the resin plate during resin molding thereof, and changes in magnetic field occurring in the removed portion due to the current flowing in the relay busbar are detected by the magnetic sensor, and the value of the current flowing in the relay busbar is measured.
