  Further, in any of the connector fittings 50 </ b> A to 50 </ b> C of the first to third embodiments, the board engaging portion 70 extends from each of both ends of the connector engaging portion 60. This structure is a more preferable structure for restricting the connector to a highly accurate position and posture with respect to the circuit board. However, the board engaging part 70 may extend only from one end of the connector engaging part 60. Even with the board engaging portion 70 extending from only one end, it is possible to regulate the position and posture of the connector with high accuracy. For example, due to the limitation of the circuit board layout space, the circuit board 80C shown in FIG. Consider the case where it extends as indicated by the chain line. In this case, you may use so that the connector fixture provided with the one board | substrate engaging part 70 may be applied to an L-shaped corner | angular. Alternatively, only one of the board engaging portions 70 extending from both ends of the connector engaging portion 60 as shown in FIG. 9 may be effectively used.

  The connector 90 in this embodiment is a type of connector that fits with the circuit board 30 (see FIG. 1). However, the connector referred to in the present invention may be a connector of a type that fits with a mating connector.
