Abstract

An electrical assembly, such as a high voltage electrical center that controls the flow of electricity between a battery pack and the propulsion system of an electric or hybrid electric vehicle. The assembly includes a plurality of electrical connectors configured to receive and mate with a plurality of corresponding mating connectors and a housing containing a plurality of electrical devices interconnected to the plurality of electrical connectors. The housing includes a bulkhead defining a plurality of connector shrouds that axially surrounds each connector in the plurality of electrical connectors. Each connector shroud is configured to receive a connector body of a corresponding mating connector. The plurality of connector shrouds is integral to the bulkhead. The bulkhead, and thereby the shrouds, may be formed of a composite conductive material containing electrically conductive fibers within a dielectric matrix.
