The electrical terminal strip is for use on a circuit board and has a number of rows of pins (9) that project from the base and these locate in holes in the board and are soldered. For each row the pins are formed on a single strip of metal. At the top of the strip the metal is formed in contact regions bent through 90 degrees (13) and these locate in screw clamping terminals (11). Holes in the insulating material housing are formed with a tapered section (4) to guide connecting wires (24) into position. The separate connector strips are sized such that insertion points are arranged at different levels.
