Abstract

A spring terminal for connecting the bare end of a conductor with a bus bar, including an insulated housing containing a chamber defined by a pair of planar parallel spaced vertical side walls, and an orthogonally connected vertical end wall. Mounted in the chamber are a vertical bus bar adjacent the end wall, and a U-shaped clamping spring that biases toward clamped electrical engagement with the bus bar the bare end of a vertical conductor that is inserted downwardly into the chamber. The clamping spring includes a stationary lower leg portion fixed to the housing, a pivotable body portion, and an upper clamping leg portion that engages the conductor, a locking arrangement serving to lock the body portion to the housing when the spring is in the clamping condition.
