The present disclosure envisages a flip cover assembly for an electrical plug-receptacle pair (210-210). The flip cover assembly comprises a flip cover (230), a first coupling element (234) and a second coupling element (240). The first coupling element (234) is formed integral with the flip cover (230). The second coupling element (234) is formed integral with the receptacle (220). The flip cover (230) is hinged to the receptacle by coupling the first coupling element (234) and the second coupling element (240). A cam (238) is configured on the first coupling element (234) to provide a moment of resistance to the rotation of the flip cover (230) from an open state to a closed state and thereby to prevent immediate closing of the flip cover (230). The flip cover assembly of the present disclosure facilitates convenient insertion of a plug in a corresponding receptacle.

An electrical junction box includes a case body on which a first opening and a second opening are formed, a first cover configured to be fixed to the case body such that the first cover covers the first opening, and a second cover configured to be fixed to the case body such that the second cover covers the second opening. The second cover is fixed to the case body by a first rotation fulcrum engaging part and an inter-cover engaging part. The first rotation fulcrum engaging part includes an engaging protrusion formed on one end of the case body, and an engaging frame formed on one end of the second cover and configured to be engaged with the engaging protrusion. The inter-cover engaging part includes a lock arm formed on another end of the second cover, and a lock arm receiving part formed on the first cover.

The present invention provides a power receptacle with protective functions, which includes a base assembly, a grounding assembly coupled to the base assembly, a first faceplate coupled to a top of the base assembly, and a cover assembly. The first faceplate includes at least one USB (Universal Serial Bus) interface slot electrically coupled to the base assembly. The cover assembly is removably coupled to the first faceplate and configured to cover the USB interface slot. The power receptacle can prevent dust and other objects from entering the slots, thereby ensuring the safety of the receptacle and prolong its life.

A mounting bracket for electrical boxes that can include a mounting body with a plurality of mounting features. The plurality of mounting features can include a first set of mounting openings that can have respective elongate directions extending in parallel. The mounting body can have a mounting body axis extending across a shortest between opposing first and second sides of the mounting body. The elongate directions of the first set of mounting openings can be disposed at an acute angle relative to the mounting body axis. The first set of mounting openings can be configured to receive a plurality of fasteners to attach the mounting bracket to a first electrical box.

A wall plate system for an electrical device, including but not limited to indoor wall switches, includes a wall plate and a shield. The wall plate defines an aperture, and the wall plate is configured to receive a portion of an electrical device in the aperture. The shield extends at least partially through the aperture, and the shield is configured to form a seal between the wall plate and the electrical device.

In an example embodiment, a junction box may include a flashing. The flashing may define a first groove. The first groove may be disposed relative to a first center axis on a first plane. The junction box may also include a housing. The housing may include a bottom portion. The bottom portion may define a second groove. The second groove may be disposed relative to a second center axis. The second center axis may be coincident with the first center axis in a direction that is substantially parallel to the first plane of the first groove. In addition, the second groove may be located on a second plane that is substantially parallel to the first plane of the first groove. Further, the second groove may be configured to indicate a suitable hole position in the bottom portion.
