PURPOSE:To prevent an adverse effect on a circuit board by pressure by slowly inserting fitting guide pins through the circuit board, and receiving the force in the insertion direction on the floor face of a device. CONSTITUTION:Fitting guide pins 16, 16' are slowly inserted into holes 15a, 15b to perform the positioning of connector housing 14 on a circuit board 15. The diameter of the second steps at the tip side of the guide pins 16, 16' is made smaller than the diameter of the first steps, and it is made equal to the diameter or width of a round hole 17a and a long hole 17b for connector positioning pins provided on the floor face 17 of a case to be fitted with the circuit board 15 to perform the positioning of the connector housing 14 and the circuit board 15 on the case. The positioning of the connector housing 14 on the opening section of the case can be determined only by the size precision of the connector housing 14, the floor face 17 of the case and the upper face of the case, and the circuit board 15 is not damaged. |
