  • Electrical wiring box with structure for fast device mounting
    Patent number: 4983785
    Abstract: An electrical wiring box of molded insulating material is provided with bosses having screw holes for receiving a mounting screw that include two colinear portions of which a first portion proximate the front surface has an internal configuration, such as molded threads, that engage the mounting screw while permitting the mounting screw to be manually inserted therethrough without turning because of flexibility built into the boss structure. A second portion of the screw hole is of greater restriction for securely engaging the screw such as by self tapping. The flexibility of the boss is provided by a first center slot that extends from the screw hole to the boss exterior over a length substantially equal to the first portion of the screw hole. Second and third slots are located respectively on each side of the screw hole and provide projections respectively between the first and second slots and the first and third slots that flex to allow easy screw insertion through the first portion of the screw hole.
