Abstract: This invention provides a fireproof separator board, which is made of a flame-retardant, high temperature resistant material and disposed within an insulating casing of an electrical device, for preventing the heat generated by the electrical components of the electrical device from being conducted to the insulating casing. This invention also provides a plug-based circuit interrupter that includes the fireproof separator board. The fireproof separator board and the plug-based circuit interrupter of this invention can effectively prevent high temperature and fire caused by the electrical components that could melt the casing.

Abstract: A faceplate for use with a GFCI (ground fault circuit interrupter) device, where the faceplate includes resilient features such as snaps to affix the faceplate to a height extension shell. The height extension shell accommodates a part of the GFCI device. The faceplate has an opening that exposes at least a part of the GFCI device. By using resilient snaps to affix the faceplate, instead of using screws as in conventional GFCI assemblies, this GFCI assembly makes installation more convenient, saves installation time, and makes the faceplate easier to clean and maintain. It also enhances esthetic without sacrificing function.

Abstract: A power plug includes a shell, input insertion plates, output power lines, a push button on the shell, and a trip assembly inside the shell for controlling electrical coupling between the input insertion plates and output power lines. The trip assembly includes a light emitting element, electrical coupling terminals, and a drive member mechanically coupled to the push button and configured to, in response to a pressing of the push button, control electrical coupling of the electrical coupling terminals, which in turn controls the electrical coupling between the input insertion plates and output power lines. The drive member includes a reflective portion that reflects a part of the light from the light emitting element to the push button as an indicator light. The dual function drive member that accomplishes both mechanical coupling and light transmission reduces the number of components. A device with an electrical control circuit is also disclosed.

Abstract: A leakage current detection interrupter (LCDI) device for an electrical appliance includes a shell and a trip assembly inside the shell. The shell includes an upper cover and a base cover joined together, and either the upper cover or the base cover includes a first cover and a removable second cover. The second cover spatially corresponds to a tail portion of the trip assembly; when it is removed, the tail portion is expose to allow a power cord to be connected to the LCDI device. By using a removable second cover, the cord can be conveniently assembled with the LCDI device when the LCDI device is installed on the electrical appliance, allowing the LCDI to be shipped without the cord. This can reduce the packed size of the LCDI device for easier shipping and storage, as well as lowering cost. It also makes the LCDI device more versatile.
