Described is a power connector device for separating an electrical connection under direct current (DC) voltage or alternating current (AC) voltage between an electrical connector element and an electrical contact element. The power connector device includes the electrical contact element. The electrical contact element has a first conductive part and a second conductive part spaced apart one from the other so as not to be directly electrically conductively connected to one another. The power connector device includes a semiconductor switch for maintaining an electrical connection between the electrical connector element and the electrical contact element during separation of contact between said electrical connector element and said first conductive part to thereby prevent arcing during electrical disengagement of the electrical connector element from the electrical contact element. The first conductive part of the electrical contact element is only electrically connected to the second conductive part of the electrical contact element when the semiconductor switch is activated or when the electrical connector element is in contact with both the first and second conductive parts of the electrical contact element.

A socket tester device includes an electrical plug that is to be inserted into an electrical socket, a tester circuit electrically coupled to the electrical plug, a sound emitting device, a communication device, a processor, and a memory. The tester circuit outputs one or more signals indicating a wiring condition of the electrical socket into which the electrical plug is inserted. The memory stores instructions that, when executed by the processor, cause the processor to receive the one or more signals indicating the wiring condition of the electrical socket into which the electrical plug is inserted, control the communication device to wirelessly transmit a first message that includes data indicating the wiring condition of the electrical socket into which the electrical plug is inserted, and control whether the sound emitting device emits one or more sounds.

A switch includes an insulating barrier that blocks an electrical conductivity path between a plug prong and a contact of an electrical receptacle. It further includes a switched alternative conductivity path between the plug prong and the contact of the electrical receptacle. A portion of the switch is inserted into the electrical receptacle. The switch receives the plug prong, and the switch is substantially flush with a wall that includes the electrical receptacle.

Various embodiments are described that relate an electrical current connector. The electrical current connector can be configured to provide electrical current when pressure is applied to a prong set. This pressure can cause a contact to engage with a connector. This can complete a circuit that allows the electrical current to flow. The connector can be coupled to a cable that can be configured to transfer data along with the electrical current. The cable can have an inner portion that transfers the data while an outer portion that surrounds the inner portion transfers the current.

A fire safety assembly includes a power supply that is pluggable into a female electrical outlet to receive electrical current from the female electrical outlet. A shut off circuit is integrated into the power supply and the shut off circuit turns off the power supply when the shut off circuit receives an alert input. A smoke detector is integrated into the power supply to detect smoke. A carbon monoxide sensor is integrated into the power supply to sense carbon monoxide. A temperature sensor is integrated into the power supply and the temperature sensor is in thermal communication with the power supply. The shut off circuit turns off the power supply when the smoke detector detects smoke, the carbon monoxide sensor senses carbon monoxide or the temperature sensor senses excessive heat.

A device for connecting an electrical fixture with electrical power supply wiring, and for mounting the fixture on a support includes a plug, a socket, and a sensing unit for at least one of wirelessly communicating a sensed condition and wirelessly receiving a signal, with the sensing unit electrically coupled to at least one of the plug and socket. The socket includes a socket body having at least one internal cavity therein with an electrically conductive contact terminal disposed within the cavity for establishing an electrical connection between the electrical power supply wiring and the socket. The plug is rigidly fixed to the fixture and insertable into the socket, with the plug having at least one male connector electrically connected to the fixture and engageable with the contact terminal within the socket to establish a circuit between the electrical fixture and the electrical power wiring. A releasable latch is carried on the combination of the plug and the socket for releasably mounting the fixture on the support.

A plug receiving device includes a main body having an inner space therein and having an open front face and an open top, wherein conductor pins to be inserted into pin holes of an outlet protrude from an outer rear face of the main body, wherein first electrical connectors are disposed on an inner rear face of the main body; a shield coupled to an inner rear face of the main body and having a vertically slidable slider; and a removable insert to be removably inserted into the inner space, wherein the removable insert has second electrical connectors disposed on an outer face thereof, wherein when the removable insert is inserted into the inner space such that the removable insert presses down the slider of the shield, the second electrical connectors are electrically connected to the first electrical connectors and then to the conductor pins, respectively.

An electrical connector assembly includes a first electrical contact device and a second electrical contact device. The first electrical contact device includes at least one first electrical contact and an actuator movable between a first position and a second position. The second electrical contact device includes at least one second electrical contact device and an interlock feature to engage the actuator when the actuator is in the first position. The actuator is in the first position when the first electrical contact is in electrical communication with a power source, and the actuator is in the second position when the electrical communication between the first electrical contact and the power source is disconnected. When the actuator is in the first position and the second electrical contact engage the first electrical contact, the interlock feature engages the actuator, thereby securing the first electrical contact device and the second electrical contact device against disconnection.

A device for protecting a plug-in connection between a first power plug of an electric appliance and a switchable power socket. The switchable power socket has a socket for receiving the first power plug and a second power plug for coupling the switchable power socket to an electrical mains. The device has a wall which, when the device is installed, at least partially surrounds the switchable power socket with the first power plug plugged therein. The wall is formed with a plug-side recess in which the second power plug at least partially penetrates the wall. The wall covers the first power plug at least partially, when the device is installed, in order to prevent the first power plug from being pulled out of the socket. A sensor detects whether or not the wall surrounds the switchable power socket and informs a control unit that controls the electrical device.

The invention relates to an apparatus and an adapter portion, the apparatus is connectable to the adapter portion and is suitable for conveying power. Each of the apparatus and adapter portion comprises an alignment portion/module configurable to facilitate contactless alignment, a contact portion/module which is capable of being coupled upon proper alignment, and a sensor portion/module configurable to impede or allow flow of power. The invention also relates to a power system including an apparatus which is pendulously coupled to a support structure and an adapter portion. The pendulous coupling facilitates alignment compensation during contactless alignment between the apparatus and the adapter portion.
