Abstract: Provided is a germ-repellent polymer structure including a base plastic selected from polypropylene homopolymer, polypropylene impact copolymer, or acrylonitrile butadiene styrene; and a hydration layer, the hydration layer including one or more hydrophilic additives formed on the base plastic optionally in the presence of an intermediate plastic that is compatible to both the base plastic and hydrophilic additives for stabilizing the hydration layer on some base plastics. In some embodiment, the introduction of hydration layer to the base plastic through the intermediate plastic imparts germ repellency by introducing sufficient hydroxyl groups onto the surface of the base plastic in order to trap water molecules into a polymer matrix of the base plastic.

Abstract: Current leakage interrupter, having a shell consisting of an upper shell and a lower shell, a PCB inside the shell, a detection device and a trip device mounted to the PCB, power lines electrically connected to the trip device through the detection device, and pins electrically connected to the trip device. The lower shell has pin holes; front ends of the pins extend out of the pin holes. A reverse hook is provided at an inner side of the lower shell at an edge of each pin hole to fix onto a first side of a rear end of a corresponding pin; a second side of the rear end of each pin is extended and bended into a bended portion; a supporting seat is also provided at the inner side of the lower shell at the edge of each pin hole to support the bended portion of the corresponding pin.

Abstract: The present invention provides a germ-repellent elastomer comprising: a base polymer selected from latex, synthetic rubber, thermoplastic elastomers, or copolymers or mixtures thereof; and at least one germ-repelling modifier selected from one or more polyethoxylated non-ionic surfactants such that a highly hydrophilic moiety is imparted from the at least one germ-repelling modifier to the base polymer either by physical or reaction extrusion.

Abstract: A leakage current protection plug includes a plug housing, a power supply cord, two copper legs embedded within the plug housing, a leakage current protection device composed of two main moving contacts. A reset button presses the moving contacts to contact the two copper legs, a winding assemble, an iron core, a circuit board assemble, an ZCT. Ends of moving contacts are arranged with contacts that conduct individually with the two copper legs upon coming into contact; the power supply cord, through the ZCT, is connected with the moving contacts; the output of the ZCT is connected with the input of the amplification circuit on the circuit board, while the output of the amplification circuit is connected with the winding assemble.
