Abstract

PURPOSE:To improve the workability of assembly by making a set screw to fix a connector mounting plate to a frame, hold other one of connector plate and the frame with the screw-on fixture. CONSTITUTION:Drilled heads 10a, 10b are made in the side edges of both the ends in the longitudinal direction in a connector mounting plate 2 so that screw holding fixtures 3a, 3b are fixed to the plate 2 by interlocking pawls 12a, 12b to the drilled heads 10a, 10b. Screw engagement holes 11a, 11b which coincide with the bottom diameters of set screws 4a, 4b are made in the screw holding fixtures 3a, 3b by threadably attaching the screws 4a, 4b to the engagement holes 11a, 11b. The screws 4a, 4b are therefore always held to the plate 2 by the screw holding fixtures 3a, 3b so that the screws 4a, 4b are never lost. It is thereby possible to improve the workability of assembly.
