ABSTRACT:
A terminal arrangement for interconnecting electrical conductors includes a plastic block (121) in which are supported a plurality of terminals (20--20) arranged in rows and columns. Each terminal is formed from a flat strip (81) of metallic material as the strip is advanced through a progressive punch and die apparatus. The terminal includes a first portion 21 which has a seam 33 that is welded to join butted longitudinal edges of that portion after it has been formed into a cylindrical shape from a flat blank on the strip. After its seam has been welded, the first portion is internally threaded to receive a terminal screw. A second portion 51 of the terminal, which is formed integrally with the first portion, has a generally square cross-section. The second portion of each terminal is disposed in a similarly configured cavity (127) of the plastic block to prevent relative rotational movement between the terminal and the block. Also, the second portion is seamed longitudinally by shear keys which resist axial forces that are imparted to the terminal during installation and use. A conductor-connecting portion, such as a wire wrapping tang, extends from the second portion to receive a conductor of a feeder or distribution cable, for example. Conductors are connected to terminals by terminal screws to connect selected conductors of a feeder cable to selected conductors of a distribution cable.
