A grounded socket and a method for insulation fault location in an ungrounded power supply system including insulation monitoring by a standard insulation monitoring device superimposing a measuring voltage on the ungrounded power supply system for determining an insulation resistance of the ungrounded power supply system. The grounded socket includes a housing having electrical contacts, a signaling device for signaling an insulation state, and a current measuring device for detecting and evaluating a differential current, the current measuring device having a measuring current transformer and evaluating electronics, and the current measuring device being configured for high-resolution detection and evaluation of a measuring current driven by the measuring voltage as a differential measuring current.

This disclosure includes a system and method for integrating a power and lighting system into one component for ease of installation under cabinets or other areas. The wiring may be split at the entrance into the chassis. Continuous power may be maintained at the receptacle locations while also powering the line voltage LED lighting via a control device such as, for example, a slide dimmer.

A power adapter may include a base wall mounted power adapter configured to be plugged into a wall power outlet and at least one extension adapter unit electrically coupled to the base wall mounted power adapter and configured to be extended away from the wall power outlet. The at least one extension adapter unit may include an electrical conduit reel configured to unravel in response to the at least one extension adapter unit being extended.

An illuminable electronic connector for facilitating connection with an electronic device has an illumination circuit with at least one illumination source, and an on-board power source for supplying power to the illumination source in at least some modes of operation. The connector may be configured to adjust brightness of the illumination source based on ambient light conditions using an on-board light sensor. A touch sensing input may also be provided to operate the illumination source. The connector may be further operable to enter a sleep mode when it enters a shipping phase of a supply chain and then to automatically activate the illumination source when it is unpackaged at the end of the shipping phase. An electronic device including an electronic visual interface, such as a mobile phone, may be also operated in a similar manner based on the phase of the device within a supply chain.

A high voltage electrical connector for electric current connections in vehicles includes a first connector unit and a complementary second connector unit releasably connectable with the first connector unit. A primary locking member is arranged in the first connector unit, and a stationary locking part is arranged in the second connector unit, where the primary locking member is electromagnetically movable between a locked position and an unlocked position. In the locked position, the primary locking member is in locking engagement with the stationary locking part preventing the first connector unit and the second connector unit from being released from each other, and in the unlocked position the primary locking member is disengaged from the stationary locking part allowing the first connector unit and the second connector unit from being released from each other.

A chassis connector comprises a housing with an insertion opening (2) for a complementary cable connector, a contact carrier inserted in the housing (1) or formed therein, electrical or optical contacts fixed in the contact carrier, and a front plate which is arranged on the front side of the housing and which, together with an annular ridge extending along at least a part of the circumference of the insertion opening, forms the front end and the outer delimitation of the insertion opening. The front plate is made of a light-dispersing or light-conducting material and has at least one coupling surface for light from an external light source.

A switched power receptacle that can be programmed to provide power for a user-selected duration in a user-selected cycle. The invention can be plugged into a conventional receptacle, extension cord, or other source of power. One or more user inputs and displays are provided so that the user can program the cycle for switching on the power (once every 2 days, once every 7 days, etc.). One or more user inputs are provided so that the user can select the duration of activation for each cycle (1 hour, 3 hours, etc.). Status indicators are preferably provided so that the user can easily monitor the operation of the device.

A coupling device is provided. The coupling device comprises a first connector with one or more primary pins and one or more drawers. The one or more drawers are configured to receive at least one of a fuse or a jumper. The one or more drawers are configured to be opened to permit the fuse or the jumper to be added or removed. The coupling device defines one or more recesses, and the one or more drawers are configured to be inserted into a recess of the one or more recesses to place the drawer in a closed state. In the closed state, the fuse or the jumper form part of an electrical circuit.

Example embodiments relate to power cords for electrically connecting one or more devices to an electrical source. A power cord may include a first end configured to couple to an electrical source and a second end configured to electrically couple to a device. A ground fault circuit interrupter (GFCI) may be coupled to the power cord between the first end and the second end such that the GFCI is configured to control a flow of electricity through the power cord to the device when the second end of the power cord is electrically coupled to the device. The GFCI may include a set of light emitting diodes (LEDs) with a first LED configured to illuminate when the GFCI is preventing the flow of electricity, and wherein a second LED is configured to illuminate when an output side of the GFCI is outputting electricity.

A power adapter may include a base wall mounted power adapter configured to be plugged into a wall power outlet and at least one extension adapter unit electrically coupled to the base wall mounted power adapter and configured to be extended away from the wall power outlet. The at least one extension adapter unit may include an electrical conduit reel configured to unravel in response to the at least one extension adapter unit being extended.
