Board positioning arrangement

摘要

An arrangement for positioning a printed wiring board relative to a rigid backplane without the need of support for the printed wiring board from below. Connector pins extend from the backplane and engage connector sockets mounted on the printed wiring board to support the printed wiring board. The printed wiring board is further prevented from falling away from the backplane by a retaining guide assembly which is mounted to the backplane and which engages the front edge of the printed wiring board at its upper end.
