The widths of 105 and 105 are set to be the same as the width of the terminal connection portion 5.

The width of the carrier 103 is set to be larger than the sum of the widths of the peripheral portions 105 and 105 and the diameter of the pilot hole 15.

In addition, the same symbol is described in the same configuration as the first embodiment, and the configuration and the function description will be omitted with reference to the first embodiment, but since it is the same configuration as the first embodiment, it is obtained. The effects are the same.

As shown in FIGS. 5 and 6, the carrier 103 having the pilot hole 15 is provided in the bent portion 27 exposed to the outside of the housing 3.

The width E of the carrier 103 is set to be smaller than the maximum width of the press-fitting portion 11, that is, the width A of the second press-fitting portion 33.

Therefore, in the carrier 103, the cross-sectional area is smaller than that of the second press-fitting portion 33 of the press-fitting portion 11, the electric resistance per unit length is made larger by the carrier 103 than that of the second press-fitting portion 33, and the amount of heat generated is the second press-fitting.

By making the amount of heat generated in the peripheral portions 105 and 105 larger than that in the press-fitting portion 11 in this way, it is possible to suppress the generation of heat in the press-fitting portion 11 together with the carrier 103, and the terminal fixing portion 25 of the housing 3 is softened due to the heat generation. Deformation can be further suppressed.

By setting the width E of the carrier 103 provided in the bent portion 27 in this way, the cross-sectional area of the carrier 103 can be made larger than the cross-sectional area of the peripheral portions 105 and 105.

Therefore, the amount of heat generated by the carrier 103 can be suppressed to be smaller than that of the peripheral portions 105 and 105, and the restoring force of the bent portion 27 generated by the heat can be reduced.

Therefore, it is possible to suppress the movement of the exposed connecting portion 7 with respect to the substrate 21 due to the restoration of the bent portion 27, suppress the occurrence of cracks in the solder portion 29 between the exposed connecting portion 7 and the substrate 21, and connect the terminal 9 and the substrate 21. Reliability can be maintained.

In such a connector 101, since the carrier 103 having the pilot hole 15 is provided in the bent portion 27 exposed to the outside of the housing 3, the heat generated by the carrier 103 is dissipated over the entire surface of the carrier 103. And further improve the heat dissipation efficiency.

Further, since the width between the terminal connecting portion 5 and the carrier 103 is set to be smaller than the maximum width of the press-fitting portion 11, the cross-sectional area of the terminal connecting portion 5 and the carrier 103 can be made smaller than the cross-sectional area of the press-fitting portion 11. The electric resistance per unit length can be made larger at the terminal connection portion 5 and the carrier 103 than at the press-fitting portion 11, and the amount of heat generated can be made larger at the terminal connecting portion 5 and the carrier 103 than at the press-fitting portion 11.

Further, since the widths of the peripheral portions 105 and 105 located between the press-fitting portion 11 and the carrier 103 and between the exposed connecting portion 7 and the carrier 103 are set to be the same as the width of the terminal connecting portion 5, the carrier. The amount of heat generated in the peripheral portions 105, 105 located around the peripheral portion 103 can be made equivalent to that of the terminal connection portion 5.

Further, since the width of the carrier 103 is set to be larger than the sum of the width of the peripheral portions 105 and 105 and the diameter of the pilot hole 15, the cross-sectional area of the carrier 103 becomes larger than the cross-sectional area of the peripheral portions 105 and 105. The amount of heat generated by the carrier 103 can be suppressed to be smaller than the amount of heat generated by the peripheral portions 105 and 105.

For this reason, in the carrier 103 provided in the bent portion 27, the amount of heat generated from the peripheral portions 105 and 105 is suppressed to be small, so that the deformation generated in the bent portion 27 due to heat can be reduced, and the terminal connection portion can be reduced.
