PURPOSE:To secure, facilitate and quicken the checking work for checking the signal at each terminal under the condition that a terminal board main body is disconnected from a printed wiring board and external wiring is connected for electrifying by temporarily holding the terminal board main body to a device side. CONSTITUTION:A terminal board 1 is fixed to a device main body 10 by screwing fitting screws 2 into screw holes 9 at two positions in the vertical direction. A stop ring 6 is installed in the fitting screw 2 at a position separated from the seat surface of a head in response to the thickness of the terminal main body to prevent the generation of fall-out of the screw 2 from the terminal board main body. Furthermore, a main fixing screw part 3, an intermediate part 4 and a fall-out preventing screw part 5 are formed concentrically and integrally with the screw 2 in order from a stop-ring 6 position toward the tip. Each length of the screw part 3 and the intermediate part 4 are determined so that the screw part 3 is fitted in the through screw hole 9 or the intermediate part 4 is fitted in the screw through-hole 9 under the condition that each connector 8a, 1a is disconnected from each other. |
