As shown in FIG. 4, the FPC 30 is a flexible substrate, and the second conductive portion 30a is exposed on the surface on the + Z side. In the present embodiment, the FPC 30 is attached to the first connector 10, but the present invention is not limited to this. For example, if it is a flat cable, it may be a cable other than the FPC 30. The "flat cable" in the claims includes the FPC30 and the flat cable other than the FPC30.

The reinforcing plate 31 is a member for protecting the connection portion between the second conductive portion 30a of the FPC 30 and the first terminal 14 of the first connector 10.

When changing to, or changing to a reinforcing plate 31-2 with a different plate thickness, a fitting hole 25 having appropriate dimensions is formed corresponding to the thickness of the FPC 30-2 or the reinforcing plate 31-2. Two connectors 20A-1 and 20A-2 must be selected.

On the other hand, in the electric connector 1 according to the present embodiment, as shown in FIG. 10, the substrate thicknesses of FPC30-1 and 30-2 and the plate thicknesses of the reinforcing plates 31-1 and 31-2 are changed. However, the reinforcing plates 31-1 and 31-2 are accommodated in the recess 26 (depending on the thickness of the reinforcing plates 31-1 and 31-2, and a part of the FPC30-1 and 30-2), and the first connector 10 is accommodated. And the second connector 20 can be fitted. As a result, the first connector 10 and the second connector 20 are fitted together without being affected by changes in the substrate thicknesses of the FPCs 30-1 and 30-2 and the plate thicknesses of the reinforcing plates 31-1 and 31-2. be able to. As a result, the versatility of the electric connector 1 can be improved.

Further, since the fitting accuracy of both connectors 10 and 20 can be maintained without reducing the design tolerance between the first connector 10 and the second connector 20, the manufacturing cost can be suppressed.

Further, in the present embodiment, the lower surface 16 of the first housing 11 of the first connector 10 is the bottom of the fitting hole 25 of the second connector 20 in a state where the first connector 10 is fitted to the second connector 20.

On the other hand, in the present embodiment, as shown in FIG. 9B, the lower surface 16 of the first housing 11 is arranged so as to face the bottom wall surface 25a of the fitting hole 25, while the reinforcing plate 31-. 2 is housed in the recess 26 (and FPC30-2 depending on the thickness of the reinforcing plate 31-2). As a result, the first connector 10 can be fitted to the second connector without rattling.

Further, in the present embodiment, the FPC 30 is attached to the lower surface 16 in a state of being in contact with the convex portion 17 formed on the lower surface 16 of the first housing 11. Therefore, the FPC 30 can be attached to an appropriate position on the lower surface 16 with reference to the convex portion 17. As a result, in the state where the first connector 10 is fitted to the second connector 20, the FPC 30 is appropriately arranged without interfering with the second housing 21 of the second connector 20.

Further, in the present embodiment, as shown in FIG. 7B, the guide convex portion 21c is fitted into the guide concave portion 11c in a state where the first connector 10 is fitted to the second connector 20. .. This makes it possible to position the first connector 10 in the height direction (Z-axis direction) with respect to the fitting hole 25 of the second connector 20. As a result, the first connector 10 can be fitted in an appropriate position in the fitting hole 25 of the second connector 20.

Further, in the present embodiment, the guide protrusions 11a and 11b are fitted into the guide recesses 21a and 21b in a state where the first connector 10 is fitted to the second connector 20. This makes it possible to position the first connector 10 in the width direction (X-axis direction) with respect to the fitting hole 25 of the second connector 20. As a result, the first connector 10 can be fitted in an appropriate position in the fitting hole 25 of the second connector 20.
