The auxiliary board joining structure further includes a plurality of positioning holes (6) formed in the main board (1), a plurality of positioning pins (20) formed on the main board (1), wherein the plurality of positioning pins (20) extend through the corresponding positioning holes (6) so as to be oriented parallel to the axial direction of the joint pins (17). Each of the positioning pins (20) has a height regulating face (23) for regulating a distance that the positioning pins are extended through the corresponding positioning hole (6). Each of the positioning pins (20) is formed long enough to be extended through the corresponding positioning hole (6) before the joint pins (17) are extended through the corresponding through-holes (5), when the main board (1) and the auxiliary board (10) are engaged. |
