A charging device is provided. The charging device includes an output terminal unit connected to an input terminal unit of a battery pack. The output terminal unit includes a terminal body including an output terminal connected to the input terminal unit and a terminal cover which covers the output terminal before the input terminal unit of the battery pack is connected to the output terminal unit and through which the output terminal passes while the input terminal unit of the battery pack is connected to the output terminal unit.

A seal cover (1) is provided for closing an opening portion (10) in a device in which a standby connector (11) is disposed. The standby connector (11) includes male terminals 11B for switching a state of an energizing circuit between a conductive state and a non-conductive state. Female terminals (23B), a shaft seal (25) and an O-ring (230) are arranged in such a positional relationship that a time point when the shaft seal (25) is compressed maximally, a time point when the O-ring (23D) is compressed maximally and a time point when the female terminals (23B) are resiliently deformed maximally do not overlap with each other when the seal cover (1) is mounted on the opening portion (10).

An electrical outlet assembly includes a sub-faceplate having a front surface and first set of contacts position on the front surface. An outer faceplate includes an outer surface and an inner surface, the inner surface having a second set of contacts. The outer faceplate is releasably connected to the sub-faceplate so that the first set of contacts connect to the second set of contacts.

A power supply circuit breaking device includes a first connector housing, a second connector housing, a main lock unit locking in a finally fitted state in which the second connector housing is completely fitted to the first connector housing, a sub-lock unit locking in a temporarily fitted state in which a part of the second connector housing is fitted to the first connector housing, a main switch unit switched on in the finally fitted state and the temporarily fitted state, and a sub-switch unit switched on in the finally fitted state and switched off in the temporarily fitted state. The sub-lock unit includes a sub-lock claw formed in the first connecter housing, and an operation portion provided in the second connector housing and having an engaging plate portion engaged with the sub-lock claw in the temporarily fitted state.

An electrical connection point including a functional block that includes a functional faceplate and a rear electrical plug and including a base that includes a housing to receive the functional block in a plugged in position. To reduce the risk of accidental detachment of the functional block, while improving the removable character of its fixing, the electrical connection point includes a lock with a ring that surrounds the functional faceplate and is disposed so as to be accessible from the outside of the housing when the functional block is received in the housing, the ring being rotatable relative to the rear electrical plug between an unlocking position to place the lock in the unlocking configuration and a locking position to place the lock in the locking configuration when the functional block is in the plugged in position.

A system, method, and apparatus for retrofitting a fluorescent light fixture accommodating an LED-based lighting system. A track is electrically connected to the driver module. The track includes at least one electronic conductor that is connected along the length of the track. At least one track adapter may connect to the track, and the track adapter includes a locking mechanism that allows the track adapter to connect to the track at any location along the track and the track may be removed. The locking mechanism may permit the track adapter to be removable. At least one light engine module can connect to the track and may also be removable.

A receptacle connector includes a receptacle including an insertion port into which a plug is inserted, a lid configured to open and close the insertion port and maintain, while the plug is inserted into the insertion port, a state in which the lid is opened by the plug, and a switch configured to change over according to the opening and closing of the lid.

A controlled-power RJ45 socket includes a housing having a cavity to receive an RJ45 plug. The socket further includes electrical contacts positioned in the cavity and that come in contact with electrical contacts of the RJ45 plug when the RJ45 plug is plugged into the RJ45 socket. A switch is positioned to disconnect the power to the electrical contacts of the RJ45 socket before the electrical contacts of the RJ45 plug are physically detached from the electrical contacts of the RJ45 socket during a de-mating of the RJ45 plug from the RJ45 socket.

An apparatus for emergency disconnection of a battery charge inlet of an electric vehicle may include a case; a handle mounted in the case, and rotatable by partially exposing through a groove formed at one side of the case; and an emergency disconnection cable having one side connected to the handle, and having the other side connected to an emergency disconnection lever provided in an inlet actuator mounted on the inlet for charging an electric vehicle.

An arc prevention system including a jack having a receptacle, a modular plug sized to be positioned in the receptacle of the jack, the modular connector including, a plurality of contacts, with at least two of the contacts creating an energized electrical path with an external power source in electrical communication with the external power source, a latch extending from a top surface of the modular plug, a switching unit positioned on the latch, a control circuit in electrical communication with the switch and the at least two energized contacts, where the electrical path between the control circuit and the switching unit is not energized, and the control circuit adjusts the energized electrical path to a predetermined electrical level.
