Panel mountable terminal block

Terminal block (10) mountable without fasteners in a panel cutout (152) such as a power port of an appliance, with a cable strain relief clamp (58) and an array of termination sites (20) for interconnection of terminals (188) of cable conductors (190) with terminals (86) of internal wire conductors (186). The terminal block includes a body (12) of insulating material with tabs (34) adapted to engage notches (162) in edges of the cutout (152). As the body (12) is slid sideways, ears (50) on the body (12) engage one side of the cutout (152) and embossments (48) snap into engagement with cutouts (152) on an opposite side thereof. Terminals (86) of conductors (186) are removably fixable to the housing at said termination sites (20). Bosses hold each terminal (86) of a conductor (186) against a support surface with a nut captured in a wall portion below the terminal (86).
