PROBLEM TO BE SOLVED: To surely carry out tentative fixation of pin head connectors to a circuit board, even in the case of hole diameters of pin insertion holes being slightly uneven at the time of manufacture. SOLUTION: This structure comprises pin head connectors 15 of which a plurality of pin terminals 17 are arranged in a row at even intervals, and a circuit board 11 having pin insertion holes 13 into which a plurality of the pin terminals 17 are inserted and then of which circumferential conductive parts 23 are mutually soldered with the terminals 17. Only a pitch between neighboring two pin insertion holes 13 in the center of the circuit board 11 is adjusted to be about 1.9mm, smaller than the pitches 2.0mm of the pin terminals 17. When the pin terminals 17 are inserted into the pin insertion holes 13, the pin terminals 17 corresponding to the pitch differing positions push the inner circumferences of the pin insertion holes 13 and tentatively fix the pin header connectors 15 in the circuit board 11. |
