Tamper-resistant assembly with wear-resistant shutters

摘要

A tamper-resistant assembly for an electrical device, such as an electrical receptacle, includes a housing enclosing movable shutter members, each having a ramped surface protected by an overlying winged cover member engageable by an object, such as a plug blade, inserted in an opening in the electrical device. Each shutter member has a pair of pockets on opposite sides of the ramped surface that anchor the wings of the cover member. The pockets extend laterally outward from the sides of the ramped surface, and the wings of the cover member are configured such that they flex inward during assembly and then snap into the pockets. Other mating features of the cover member and the shutter member help ensure secure anchoring of the cover member.
