Abstract:
A pre-defined conduit knockout is formed as a unitary part of an electronics enclosure so that before its removal the knockout is joined to the housing at a continuous unbroken surface, thereby preventing debris and liquid from entering the housing from around the knockout. The knockout is bounded by a reduced thickness break-away section of an enclosure wall that shears apart to separate the knockout from the enclosure. The knockout is formed with a unitary, pocketed tool receptor adapted to receive a tool, such as a screwdriver or pliers, for twisting the knockout free of the housing without the need to apply an impact force, which could upset sensitive electronics in the enclosure. Methods of forming the knockout in, and removing it from, an electronics housing are also disclosed.
