Abstract
Abstract A terminal box arrangement with an insulated housing member having side and end walls. The end walls have apertures therein, for guiding electric conductors into the housing. Mounted inside the walls of the housing is a leaf spring, the free ends of which intersect the axes of the apertures, providing locking means for conductors entering the housing through the apertures. Tool passageways are positioned in each end wall, adjacent each of the apertures, providing access to the arms of the leaf spring.
