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 frame having openings corresponding to socket holes of the power receptacle, and a sliding block assembly and a resilient member disposed in the frame. The sliding block assembly include a sliding block body with two inclined surfaces, at least one of which having a slot to receive a wear-resistant block. In the initial state, the resilient member urges the sliding block assembly to cover the openings. The frame further includes a position limiting member and a balancing support member. When an inserted object pushes on only one of the two inclined surfaces, the position limiting member limits a sliding motion of the sliding block assembly; when two inserted objects simultaneously push on the two inclined surfaces, the sliding block assembly is balanced on the balancing support member and slides along the frame to expose the openings.

Abstract: A power plug with leakage current detection and protection interrupter and arc protection includes: a shell, a trip assembly disposed within the shell, a cable connector electrically coupled to the trip assembly, and an arc protection shield disposed between the trip assembly and the shell. The trip assembly includes a switch having input and output contact terminals. The arc protection shield is configured to isolate the input and output contact terminals of the switch from the shell. The arc protection shield includes one or more arc blocking baffles, each disposed near corresponding input and output contact terminals, so as to isolate the contact terminals from the shell. By providing the arc protection shield between the input and output contact terminals and the shell, the shell is protected from arcs formed at the input and output contact terminals due to connection and disconnection operations. This prevents damage to the shell and improves user experience and safety.

Abstract: A power track system includes a leakage current protection assembly, a track board, and track sockets slidably disposed on the track board. The leakage current protection assembly includes an input end for coupling to a power source and an output end coupled to electrical conductors within the track board to provide electrical power to the track board. The track board is electrically coupled to the track sockets to provide power thereto. The track sockets have socket holes to receive an electrical plug of a load, and is slidable to different positions of the track board. The leakage current protection assembly functions to cut off electrical connection between the input and output ends when any one of the track board, track sockets and load has a leakage fault that exceeds a threshold value. The power track system can provide leakage current protection function while supplying power to the loads.

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: A core unit for a leakage current detection and interruption device includes a control circuit board; a drive coil assembly coupled to the circuit board, including a coil holder frame and an input or output assembly connected thereto; and a magnetic movement assembly nested with the drive coil assembly, including a magnetic movement frame and the output or input assembly connected thereto. In response to relative movements between the drive coil assembly and the magnetic movement assembly away from or toward each other, the input and output assemblies are disconnected from or connected to each other, respectively. The core unit achieves reset function and trip function by the coordination of the drive coil assembly and magnetic movement assembly, effectively ensuring power connection and disconnection while reducing the number of components. This design reduces the size of the device and reduces assembly cost.

Abstract: A leakage current protection device includes a shell and a core assembly disposed within the shell. The core assembly includes a control circuit board, a trip assembly disposed on the control circuit board, and an input end and an output end connected to the trip assembly. The trip assembly includes a first driving member movable linearly in a first direction and a second driving member pivotable around a pivotal support axis, where the first and second driving members are mechanically engaged with each other and move together with each other. The second driving member has two driving points configured to move in a second direction as the second driving member pivots, the second direction being non-parallel to the first direction. Movements of the two driving points of the second driving member in the second direction are operable to electrically connect or disconnect the input and output ends.

Abstract: A power receptacle includes a receptacle body having first snap slots, and an outer cover disposed over the receptacle body, having first snap hooks and second snap hooks. The first snap hooks detachably engage with the first snap slots. The receptacle further includes a reset button cap and a test button cap disposed on the outer cover, each cap having second snap slots which engage with the second snap hooks in a detachable and slidable snapping engagement. The snap engagements allow the outer cover to be conveniently installed on the receptacle body, and allow the user to depress the reset button cap and test button cap to activate the reset button and test button inside the receptacle. When the outer cover is worn or damaged, it can be conveniently detached from the receptacle body and replaced.
