<p><P>PROBLEM TO BE SOLVED: To meet a larger current than before by using a terminal block in a wiring board unit in which a power module is mounted in a printed circuit board. <P>SOLUTION: The wiring board unit includes a printed circuit board (2), and a terminal block (10) which connects a power module (3) mounted on a printed circuit board (2) and an electrical wiring (8). The terminal block (10) includes a terminal connection (11) to which the power module (3) is directly connected and a wiring connection (12) to which the electrical wiring (8) is connected. In the printed circuit board (2), a hole (2c) which is larger than the plane orthographic projection area of the terminal connection (11) is formed. The terminal connection (11) is located under or over of the hole (2c) of the printed circuit board (2). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
