  • Patent number: 9768554
    Abstract: An electrical plug assembly including a plug housing, a ground pin and a first power blade projecting from the surface of the plug housing; and a power socket disposed within the plug housing. The surface defines an aperture surrounding the power socket. The assembly further includes an adapter plate including a second power blade having a first portion projecting from a first surface and a second portion projecting from an opposed second surface. Ground pin and first power blade apertures extend through the adapter plate. The second portion of the second power blade is received within the power socket and the ground pin and the first power blade are received within the ground pin and first power blade apertures respectively. The ground pin and the first power blade each project from the first surface of the adapter plate. The adapter plate allows the plug assembly to meet NEMA 5-15P or 6-20P standards.

  • Patent number: 9634435
    Abstract: An electric vehicle supply equipment (EVSE) assembly for an electric vehicle (EV) or plug-in hybrid electric vehicle (PHEV), often referred to as, optionally having one of at least two interchangeable power supply cords with plugs that conform to different technical standards, such as National Electrical Manufacturers Association (NEMA) 5-15P or 6-20P. The interchangeable power supply cord plugs each include a thermistor adapted to monitor plug temperatures. The electronic module is configured to disable charging until a proper resistance of the thermistor in the plug is detected. The electronic module is also configured to automatically switch between 120 volt and 240 volt operation based on which of the interchangeable power supply cords is connected to the electronic module.

  • Patent number: 9608357
    Abstract: A connector assembly, such as a high voltage electrical connector assembly, includes a first connector having a first housing and an intermediate housing attached to the first housing. The intermediate housing is moveable from a first position to a second position. A flexible retaining arm is configured to hold the intermediate housing in the first position. The connector assembly further includes a second connector having a second housing. The second housing defines a release wedge that engages and flexes the retaining arm, thereby releasing the intermediate housing from engagement with the retaining arm and allowing the intermediate housing to move from the first position to the second position as the first connector is connected to the second connector. A terminal in the first housing is enclosed within the intermediate housing in the first position, and protrudes from an aperture in a surface of the intermediate housing in the second position.

  • Patent number: 9455523
    Abstract: A right angle connector assembly including a first connector having a mating assist slider configured to slide along a first axis defined by the first connector and a second connector having a second housing and an intermediate housing attached to the second housing that is configured to slide along a second axis defined by the second connector that is substantially perpendicular to the first axis. The intermediate housing is configured to receive the first connector along the first axis. When the mating assist slider is moved along the first axis from a starting position to and ending position, the mating assist slider moves intermediate housing along the second axis from an initial position to a final position, thereby mating a first terminal within the first connector to a second terminal within the second connector at a right angle or ninety degree orientation.

  • Patent number: 9431771
    Abstract: An electromagnetically shielded connector system includes a first and second connector. The first connector further includes a first terminal and a first electromagnetic shield surrounding the first terminal. The first shield defines a flexible interface contact projecting from an end of the first shield. The second connector further includes a second terminal configured to mate with the first terminal and a second electromagnetic shield surrounding the second terminal. The second shield is configured to be electrically connected with the first shield at least via the flexible interface contact. The second shield is surrounded by a supporting member. At least a portion of an outer surface of the second shield is in intimate contact with the supporting member. The second shield is configured to be disposed intermediate the interface contact and the supporting member. The interface contact is formed and configured to exert a normal spring force on the second shield.

  • Patent number: 9270055
    Abstract: A connector having a connector body defining a first protrusion and a connector position assurance (CPA) device in the form of a sleeve axially surrounding the connector body that is moveable along a mating axis. The sleeve defines a second protrusion configured to engage the first protrusion when a first force is applied to the sleeve as the connector is mated with a corresponding mating connector. The second protrusion is configured to slide over the first protrusion and then disengage the first protrusion when a second force is applied to the sleeve, thereby producing a vibratory response in the sleeve. The vibratory response is a tactile vibration or an audible vibration. The second force applied to the sleeve is greater than the first force and the second force may be applied to the sleeve in the same direction as the first force or in the opposite direction.
