Abstract: A multiplex electrical outlet receptacle comprises a housing containing four or more receptacle outlets. The housing contains at least one tab extending from the top of the housing and at least one tab extending from the bottom of the housing to permanently secure the housing to an in-wall electrical box. A single electrical cable connection on the housing connects each of the four or more electrical receptacle outlets to a power source. The housing of the multiplex electrical outlet receptacle includes internal wiring and/or buses to connect each of the outlets in common to the electrical cable.

Abstract: A modular electrical receptacle wherein more than one of the modular electrical receptacles can be connected to form a larger receptacle connected to a single source of power. The modular electrical receptacle includes a housing having a front surface with a first and a second electrical outlet. The housing further includes a first tab extending from a first end and a second end extending from a second end for securing the modular receptacle to an in-wall electrical box. The housing further includes a power link, such as a conductive extension, for connecting directly to another module and providing the other module with access to the single source of power. The power link can be three links for connecting a positive line, a neutral line and a ground line to the another module. The housing also includes a coupler for connecting the housing to a power link of another module. Again, three couplers can be provided for the positive, neutral and ground lines.

A single electrical cable connection on the housing connects each of the four or more electrical receptacle outlets to a power source. The housing of the multiplex electrical outlet receptacle includes internal wiring and/or buses to connect each of the outlets in common to the electrical cable. Additionally, a two-sided multiplex receptacle and a corresponding electrical box are configured to provide electrical outlets to both sides of a wall. Additionally, a multi-receptacle plug-in adapter configured to allow more than one transformer type plug to connect to the adapter at the same time.
