<p>A connector for reduced insertion force includes one or more U-shaped insulators, each having two portions and a gap between them to receive a printed circuit board. A conductor is held by each insulator so that part of the conductor is free to move between first position in which the conductor extends into the gap and a second position retracted from the first position. In the first position, the conductor can make good electrical connection with a printed circuit board inserted into the gap; in the second position, the conductor exerts little or no force on the printed circuit board and therefore allows easier insertion of the board into the gap. The conductor may be a single M-shaped conductor or one or more generally U-shaped conductors attached to an insulator structure in the form of a wafer. A plurality of such wafers may be stacked so that their gaps are aligned and their conductors are spaced apart by a distance corresponding to standard printed circuit spacings. Channels are provided through the insulator to allow an elongated movable means to be inserted therein to engage the connectors when they are in one of their positions and urge them into the other position.</p> |
