ABSTRACT:
A unitary molded plastic backplane (12) having high strength and resistance to flexing, includes spaced pedestals which project from one side of a main body (34) and which support connector plugs (14) on the backplane (12). Stepped edge and center portions (56, 57 and 60) of the backplane (12) define elongated recesses (58, 59 and 61) for receiving other associated support members (22, 24 and 26). The pedestals (36) and stepped edge portions (56 and 57) define channels (40, 41 and 42) for receiving wires (18) interconnecting the connector plugs (14) and input/output connectors (16) on the backplane (12). Integral support legs (44) project from the one side of the main body (34) beyond the connector plugs (14). Projecting cylindrical housings (68) receive mounting screws (66) to preclude tightening of the screws down onto adjacent wires 18. Alignment of the backplane (12) in associated equipment is facilitated by alignment tabs (48), tab-receiving recesses (50) and projecting lugs (62 and 64).
