Abstract: An elongated electrical connector, elongated insulator block for holding several of the connectors and a jig or tool for assembling the block and connectors to a printed circuit board. The connectors are each provided with an intermediate mounting boss or plate with an opening that matches an opening in the side of the elongated block. The jig includes a series of movable claws which extend into the connector openings to align the connectors and drive them into matching apertures of a printed circuit board.
