Abstract: A connector for electric vehicle supply equipment includes: a housing that includes one or more electrical coupling members that are connectable between the electric vehicle supply equipment and a mating inlet of an electric vehicle to supply electric power to the vehicle. The housing includes a sensor for detecting light within the housing and outputting a signal in response to a detection of light within the housing to interrupt or disable the supply of electric power to the vehicle through the connector.

Abstract: A connector for electric vehicle supply equipment includes: a housing; a first electrical coupling member supported by the housing and that mates with an inlet of an electric vehicle, the first electrical coupling member including a first pin part; a second electrical coupling member supported by the housing and that mates with the inlet, the second electrical coupling member including a second pin part; and a conductive barrier supported by the housing that extends between the first and second pin parts. The conductive barrier interacts with at least one of the first and second pin parts to provide a conduction path for electrical power monitorable to evaluate electrical isolation of the first and second electrical coupling members and avoid electrical arcing or short-circuiting.
