A cable system for a truck trailer with connectors having a main power connection, a ground connection, and one, two, or more communication cable connections. Connectors include at least a power and ground connection for electrically connecting an individual trailer to the cable system. A master control circuit may be included in the trailer nosebox, and the master control circuit configured to send commands to slave control circuits mounted within the connectors. The slave control circuits in the connectors are configured to receive a control command sent by the master control circuit that may include an address, mode identifiers, or other indications of which connectors in the cable system should take action, and what actions should be taken.

An electrical outlet device and system for providing light and power during the night or during a power failure. The device and system includes rechargeable energy storage devices that can be utilized to provide power to the outlet(s) and the light sources. The device and system can have two sections, a main and a removable section both having their own energy storage devices and light sources. The removeable section may connected with a computing device that can interface with a wireless module to transmit/receive data packets wirelessly.

Central vacuum cleaning system comprising a vacuum source including: a motor within a motor housing and a motor control circuit connected to the motor; a handle to be held by an operator, a flexible hose for connecting the handle to a conduit system that is connected to the vacuum source; a user input interface at an input location on the handle for controlling an operation of the motor through the motor control circuit; and a communications system to transfer control signals from the user input interface to the motor control circuit wherein the communications system comprises an RF wireless transceiver in the handle, and an RF wireless transceiver at the motor control circuit.

A connector assembly for connecting a first electrical component to a second electrical component includes a circuit board which is electrically conductively connectable to the first electrical component. A plug unit is electrically conductively couplable, at a plug end, to a mating plug unit and is disposed on a first side of the circuit board. A light source is disposed on a second side of the circuit board opposite the first side. A light guide has an in-coupling region and an out-coupling region, and a through-hole in which the plug end of the plug unit is at least partially disposed. The light guide also has a light injection opening in which the light source is at least partially disposed. The in-coupling region is disposed on a side wall of the light injection opening, and the out-coupling region surrounds the through-hole.

A powered wall plate comprising a wall plate, at least two electrical plug prongs, an electrical circuit, and an electrical feature. The wall plate has a front surface opposite a rear surface and at least one opening sized to expose a first electrical receptacle of an electrical device. The at least two electrical plug prongs originate within the wall plate and extend rearward from the rear surface, and are configured to removably mate with a second electrical receptacle of the electrical device. The electrical circuit is located between the front surface and the rear surface. The electrical feature is exposed on the wall plate and is configured to receive power from the at least two electrical plug prongs through the electrical circuit. The wall plate may have a profile with a first thickness and a second thickness. The second thickness may be less than three times the first thickness.

A charging inlet assembly includes a housing having a DC section with DC terminals received in DC terminal channels for mating with a DC charging connector and AC terminals, including a proximity terminal, received in AC terminal channels for mating with an AC charging connector. The charging inlet assembly includes an HMI assembly coupled to the rear of the housing having a control circuit board, a charging indicator coupled to the control circuit board visible from the front of the housing to indicate a charging status of the charging inlet assembly, and a proximity resistor assembly coupled to the housing. The proximity resistor assembly includes a resistor coupled to the control circuit board and a cable connector connected between the control circuit board and the proximity terminal.

An electrical plug provides protection against electrical surges with a replaceable surge protector cartridge that is readily removable and replaceable along an exterior of the plug. Surge protector circuitry in the cartridge can absorb an electrical surge received at the plug from an electrical mains source, and the electrical plug can maintain electrical continuity from plug prongs to an electrical cord both before and after the surge protector has absorbed an electrical surge.

A tamper resistant nightlight for placement in an electrical receptacle, the nightlight includes a body that has a base with an LED circuit and plug blades extending from the body. A housing includes a locking element configured to restrict a child from removing the nightlight from the electrical receptacle through a flange that extends away from the body to be positioned behind a rear surface of an electrical wall plate associated with the electrical receptacle to prevent the tamper resistant nightlight from being removed from the electrical receptacle while the electrical wall plate is coupled to the electrical receptacle.
