Abstract
A plug-in connector arrangement includes a terminal block containing a chamber in which are mounted a horizontal bus bar having a transverse wall, and a resilient contact having a fixed horizontal leg portion, an intermediate portion bent upwardly from the first leg portion, and an outwardly biased second leg portion reversely bent back above the first leg portion. The second leg portion contains a clamping end portion that extends through a conductor opening contained in the first leg portion. The clamping portion includes at least two discrete clamping surfaces so arranged that when a bare conductor is inserted into the conductor opening, the conductor circumferential surface is selectively engaged by one or more of the clamping surfaces in accordance with the diametrical size of the conductor. The conductor is biased by the clamping portion toward electrical engagement with the bus bar transverse wall.
