<p>The connector comprises two similar elements (12 and 13) each with a tongue (20) disposed between and in a plane parallel to the arms (24 and 26). The elements (12 and 13) slide together as shown and are then rotated about an axis perpendicular to their planes such that the tip of tongue (20) on one element engages straight edges (28) of arm (24) on the other element while extensions (34 and 35) at the root of the tongue engage convex edge (30) of arm (26) of the other element. The arms are thus forced apart and exert a resilient grip on the tongue. …<??>Such connectors arranged in a plane perpendicular to the boards may serve as connecting hinges between printed circuit boards. …<??>In alternative constructions the connector elements are assymetrical, one having a spreader element which engages between resilient arms of the other and spreads them apart upon rotation. The spreader element itself may have a slot engaged by a spreader on the other connector element.</p> |
