Quarter turn fastener

摘要

A quarter turn fastener includes a deflectable head and part in assembly legs for securing the fastener in a subassembly with one component positioned between the deflectable head and the part in assembly legs. Cooperating lock arms on the fastener and lock ribs on the component secure the fastener against unintended rotation for loosening. Stop ribs on the component limit the distance the fastener can be rotated. Main body legs are provided for securing a second component with the subassembly. Cooperating structures of the fastener and the components limit the fastener to rotate only in the lock direction from the unlocked position and in the unlock direction from the locked position.

主权项

1. A fastener for securing first and second components to one another in an assembly, said fastener comprising:
a main head; a deflectable arm having a proximal end connected to said main head, said deflectable arm projecting laterally from said main head to a distal end of said deflectable arm, said deflectable arm and said main head defining a deflection space therebetween into which said distal end and said arm are received upon deflection of said deflectable arm; a turn tab projecting outwardly from a surface of said main head, said turn tab configured for manual manipulation when turning the fastener; a pedestal projecting from a surface of said main head opposite from said turn tab; a first deflectable leg projecting from said pedestal and having a ledge defining a first distance from said main head; and a first main body leg projecting from said pedestal and having an upper surface defining a second distance from said main head, said second distance being greater than said first distance.
