Protective Electrical Wiring Device With Tamper Resistant Shutters

摘要

The present invention is directed to an electrical wiring device that includes a frameless shutter assembly that is disposed in the front cover portion or in the at least one separator member between the plurality of receptacle openings and the plurality of receptacle terminals. The at least one frameless shutter assembly comprises a first shutter member and a second shutter member configured to move from a closed position to an open position when the hot and neutral blades of a plug blade set are simultaneously inserted into the receptacle openings to engage a set of receptacle terminals and remain closed otherwise. The front cover member and/or the at least one separator includes a first stop member disposed proximate the first shutter member and a second stop member being disposed proximate the second shutter member. The first stop member and the second stop member are configured to prevent a foreign object from accessing one of the plurality of receptacle terminals after being inserted into a corresponding one of the receptacle openings.
