  • AUTOMATION COMPATIBLE SPRING ASSISTED SINGLE PART TAMPER RESISTANT SHUTTER MECHANISM FOR WIRING DEVICE PRODUCT
    Publication number: 20220328997
    Abstract: A shutter assembly for a tamper-resistant electrical receptacle includes a shutter, a base clip, and a spring. The shutter is coupled at one end by the spring to the rear side of an individual outlet cover of the electrical receptacle, and two multi-sloped blocking mechanisms of the shutter block access to the live electrical terminals from the hot and neutral slots of the outlet cover when a plug is not inserted into the outlet. The shutter comprises a fulcrum that rests on the base clip, which allows one end of the shutter to interlock with divots formed in the rear side of the outlet cover and the other end of the shutter to interlock with the base clip in order to prevent access to the live electrical terminals when an object is inserted into only one of the hot or neutral slots of the individual outlet cover, or when an object is inserted into the outlet cover at a tilted angle.
