A pair of printed circuit boards (11, 12) angularly converge towards each other about a pivot axis (13). Each of the boards (11, 12) carries a connector housing (16). The connector housings (16) are identical, but are inverted end-to-end with respect to each other, such that a plurality of hermaphroditic guide fingers (19) on one of the connector housings (16) will mesh with a complementary plurality of guide fingers (19) on the other connector housing (16). The meshing engagement of the guide fingers (19) provides a guide means and a stop means between the connector housings (16) and hence between the printed circuit boards (11, 12). Each of the identical connector housings (16) further has a flexible electrical connector (17), and the flexible electrical connectors (17) engage each other when the printed circuit boards (11, 12) are fully converged. Inclined surfaces (21, 22) on the meshing guide fingers (19) provide a self-alignment feature as the printed circuit boards (11, 12) and the connector housings (16) thereon are angularly converged. Preferably, each connector housing (16) has spaced-apart pairs of bifurcated latching fingers (23) such that the connector housing (16) is "snapped" on to its respective printed circuit board (11, 12).
