Abstract: A leakage current protection device with charging power output, including a shell and a core assembly disposed within the shell. The core assembly includes: a ground fault circuit interrupter assembly, including a first control circuit board, and a first input assembly and a first output assembly coupled to the first control circuit board; and a charging power supply assembly, including a second control circuit board, and a second input assembly and a second output assembly coupled to the second control circuit board, wherein the second control circuit board is disposed perpendicularly to the first control circuit board, and is electrically coupled to the first control circuit board by the second input assembly. While ensuring reliability of the leakage current protection function, the spatial layout of the components achieves large current power output and fast charging power output in a relatively small space.

Abstract: A safety shield assembly for a power receptacle includes a slider frame and first and second slider blocks disposed therein. The slider frame has a bottom panel and a perpendicular sidewall along a periphery thereof. The bottom panel defines first and second openings having shapes corresponding to shapes of socket holes of the power receptacle. The first and second slider blocks respectively have first and second blocking portions respectively corresponding in position to the first and second opening. The bottom panel of the slider frame further includes guiding members, where the first and second slider blocks move within a space defined by the sidewall, as guided by the guiding members and under spring force of resilient members, between first positions where the first and second openings are covered, and second positions where the first and second openings are exposed. The safety shield assembly is reliable, safe, and convenient to use.

Abstract: An LCDI device includes a shell, a movement unit, and a wire bundle assembly. The shell includes a base and an upper cover connected to each other. The movement unit is disposed in the base, and includes at least one connecting conductor. A first end of the wire bundle assembly is disposed in the upper cover and includes at least one shield detection line, where the shield detection line is electrically coupled to the connecting conductor. The shield detection line includes a connecting terminal at the first end of the wire bundle assembly which is configured to received and retain the connecting conductor inserted therein. The structure of the LCDI enables fast and secure assembling of the wire bundle assembly and movement unit, and eliminates the need for internal re-adjustment of the shield detection lines after assembling, which promotes automation of large scale production.
