To secure connecting work for joint of adjacent printed boards by inserting a connecting terminal provided on a metallic enclosure into a hole drilled, in advance on a printed board, connecting the connecting terminal with the printed board through soldering, and separating the connecting terminal by every terminal.

Just after a printed board 1 has been inserted into a metallic enclosure 7, it is inserted into a comb-tooth like part of a connecting terminal 5, which is formed through bending in a hole 4 drilled in advance on a printed board 1. Then the enclosure 7 is connected to the board 1 through soldering, and at the same time, the terminal 5 is connected to the board 1 through soldering, in the comb-tooth like part of the terminal 5, that is, a tie bar 6. The tie bar 6 is cut off, so as to change the terminal 5 into individual independent multipolar terminals. Thus a work for connecting to adjoining printed boards can be surely done, and the number of steps be reduced also.
