Input adapter for a bus bar system

摘要

An improved input adapter for electrically connecting input leads with the bus rails of a bus bar system. Connection at any desired location along the bus rails is made possible without drilling holes in the bus rails by an arrangement in which contact plates are held in an adapter housing facing and in position for contact with the bus rails, a clamping arrangement for electrical connection of each contact plate with its corresponding rail, including a U-shaped clamp with clamp ends formed at the free ends of clamp side legs and engaging behind the bus rail, a clamp screw extending adjustably through a threaded hole in a clamp cross portion to connect the contact plate and bus rail, the contact plates having threaded holes in portions away from the clamps for screw attachment of the input leads.
