PURPOSE:To feed large current to a circuit on a printed wiring board safely and certainly by fastening by screw a U-form metal piece which pinches sandwichedly a current feeding terminal block soldered fast to a wiring pattern on the wiring board. CONSTITUTION:A current feeding terminal block 18 is mounted by solder on a wiring pattern of a printed wiring board 2. The block 18 and wiring board 2 are mounted on a U-form metal piece 20 sandwichedly. A screw 14 is driven fast into a tapped hole 24 in the metal piece 20 through a hole 12a in a solderless terminal 12, a through hole 22 in the metal piece 20, a through hole 18b in the block 18, and a hole in the wiring board 2. The metal piece 20 is tightly attached to the pattern 4 on the rear surface of the board 2 while the block 18 is pressed to the pattern 4 on the front surface of the board 2, which brings about increase of the area where the piece 20 and patterns 4 are in electrical connection. This enables feeding a large current to the patterns 4. |
