  • Patent number: 4466689
    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.
