Abstract: An emotor connection arrangement for connecting power electronics of an electric or hybrid electric vehicle to an emotor. The emotor connection arrangement includes a junction box configured to extend from the power electronics to the emotor, and phase bars that extend in the junction box and electrically connect the power electronics to the emotor. A first access cover is removably connected to the junction box and configured to provide access for connecting the phase bars to the emotor, and a second access cover provides similar access for connecting the phase bars to the power electronics. In order to prevent overheating, the first access cover includes a cooling fluid channel with a cooling fluid inlet configured to be connected to a cooling fluid source and a cooling fluid outlet configured to be connected to a cooling fluid return.

Abstract: A junction assembly is disclosed herein. The junction assembly includes a junction housing configured to support a phase bar assembly. A heatsink contacts at least a portion of the junction housing and a busbar is arranged adjacent to the junction housing. At least one fastener attaches the junction housing, the heatsink, and the busbar to each other. At least one heatsink seal is provided at an interface defined between the heatsink and the junction housing.
