SCREW-UP TYPE TERMINAL BLOCK AND SCREW EXTRACTING TOOL

PROBLEM TO BE SOLVED: To facilitate pressing down of washers alone from above, and quickly, easily and reliably extract screws from screw holding holes of the washers. SOLUTION: In a screw-up type terminal block 1A, screws 2 and washers 3 are vertically raised relative to wide surfaces of terminals 5 while rotating the screws 2 for separation from holes 4 for screws of the terminal 5. The screw-up type terminal block 1A is provided with screw holding portions 63 at ceiling portions 64 of units 6A of the terminal block 1A. The screw holding portions 63 are capable of holding screws by receiving planar washers 21 of screws 2 with an energizing force of compression springs 8 while the screws 2 are insertably and withdrawably inserted into the screw holding holes 4 of the washers 3. The front end portions of drivers 101 are pressed to the top of L-shaped portions 35 of washers 3 through notch portions 65A of the ceiling portions 64, thus only the washers 3 are pressed from above. The floated screws 2 are picked up with a pair of radio pliers and are drawn out from the screw holding holes 4 of the washers 3. COPYRIGHT: (C)2009,JPO&INPIT
