PROBLEM TO BE SOLVED: To electrically and mechanically strongly couple an upper and a lower printed boards to each other in disposing the two printed boards, without increasing the number of parts or reducing a pattern surface. SOLUTION: A second connector 20 mounted on a second printed board 3 on the lower side is provided with a stopper 21 for decide an interval to a first printed board 1 on the upper side, and a threaded guide pin 22 which also acts as a positioning member, and a guide hole 23 is opened at a corresponding position of the first printed board 1 to the threaded guide pin 22. The first printed board 1 and the second printed board 3 are put to be close to each other, and a conductive pin 5 is inserted into a first connector 2, when the threaded guide pin 22 is inserted into the guide hole 23 for eliminating the relative positional deflection between them. By driving a butterfly nut 24 to the thread guide pin 22, the first printed board 1 and the second printed board 3 are electrically and mechanically coupled firmly to each other. |
