<Effects>
Next, the operation and effect of the present embodiment will be described.

  In the present embodiment, the terminal 40 includes a first contact portion 50 that conducts with the counterpart terminal 92, a second contact portion 60 that conducts with the terminal connection portion 18 b of the board fixing terminal 18, and a second contact portion 50 that extends from the first contact portion 50. A connecting portion that extends to the contact portion and connects the first contact portion and the second contact portion; The connecting portion 70 is configured such that the first contact portion 50 can be displaced relative to the second contact portion 60 in the terminal vertical direction.

Here, the upper end 60U of the terminal of the second contact portion 60 is located above the terminal upper end 50U of the first contact portion 50, and the connecting portion 70 extends to the upper end 60U of the terminal of the second contact portion 60. ing. Therefore, the length of the connecting portion 70 can be increased by utilizing the space above the terminal upper end 50U of the first contact portion 50 and below the terminal upper end 60U of the second contact portion 60.
Further, since the connecting portion 70 does not pass through a space above the terminal upper end 60U of the second contact portion 60, an increase in the vertical dimension of the entire terminal 40 can be suppressed.
As described above, a large amount of displacement of the first contact portion 50 with respect to the second contact portion 60 can be secured while suppressing an increase in the vertical dimension of the entire terminal 40.

  Further, in the present embodiment, the terminal lower end 60L of the second contact portion 60 is located above the terminal lower end 50L of the first contact portion 50. In other words, the terminal lower end 50L of the first contact portion 50 is formed to a position below the terminal lower end than the terminal lower end 60L of the second contact portion 60. For this reason, the first contact portion 50 becomes close to the substrate, and can be configured to be easily connected to the counterpart terminal 92 (first connection target) inserted from the through hole of the substrate.

In the present embodiment, the first contact portion 50 includes the front wall 51F, the pair of side walls 51S, and the rear wall 51R, and thus includes the first cylindrical portion 51 having a rectangular cross section orthogonal to the terminal up-down direction. Therefore, the rigidity of the first contact portion 50 is ensured.
In addition, since the connecting portion 70 is formed by extending the front wall 51F of the first cylindrical portion 51 above the terminal, (for example, the first extending portion 71 is formed by the rear wall 51R of the first cylindrical portion 51). The space above the first cylindrical portion 51 can be effectively used, as compared with a mode in which the space is extended above the terminal. Therefore, it is easy to secure a displacement amount while suppressing an increase in the size of the terminal 40 and the connector 10.

In the present embodiment, the second contact portion 60 includes the front wall 61F, the pair of side walls 61S, and the rear wall 61R, so that the cross section orthogonal to the terminal vertical direction includes the second cylindrical portion 61 having a rectangular shape. Therefore, the rigidity of the second contact portion 60 is ensured.
Further, since the connecting portion 70 is connected to the terminal upper end of the front wall 61F of the second cylindrical portion 61, a bent portion 74 is formed between the second extending portion 72 and the front wall 61F of the second cylindrical portion 61. As a result, it is easy to secure the displacement amount (for example, as compared with a mode in which the second extension portion 72 is connected to the side wall 61S of the second cylindrical portion 61).

  In the present embodiment, the connecting portion 70 extends from the terminal upper end 50U of the first contact portion 50 to the terminal upward, and the terminal extends from the terminal upper end of the first extending portion 71 to the terminal rearward. It includes a second extending portion 72 connected to the two contact portions 60, and a bent portion 73 formed between the first extending portion 71 and the second extending portion 72. For this reason, the long first extension portion 71 and the second extension portion 72 are connected by the bent portion 73, and a large displacement can be secured.

  Further, in the present embodiment, since the connecting portion 70 does not protrude forward of the terminal than the front wall 51F of the first cylindrical portion 51, an increase in the front-rear dimension of the entire terminal 40 is suppressed.

[Supplementary explanation of the above embodiment]
In the above-described embodiment, an example has been described in which the connecting portion 70 is connected to the terminal upper end of the front wall 61F of the second cylindrical portion 61. However, the connecting portion 70 is connected to the terminal of the rear wall 61R of the second cylindrical portion 61. It may be connected to the upper end.

  Further, unlike the above embodiment, the connecting portion 70 may be formed by extending the rear wall 51R of the first cylindrical portion 51 upward.

  In the above-described embodiment, the regulating portions 33F and 33R of the cover 30 abut on the upper end surfaces of the first tubular portion 51 and the second tubular portion 61, so that the upper surface of the first contact portion 50 and the second contact portion 60 is formed. Although the range of movement in the direction is limited, the present invention is not limited to this. For example, the projection 59 (see FIG. 9 and the like) of the first contact portion 50 and the projection 69 of the second contact portion 60 abut on the lower end surface of the side wall 30 </ b> S of the cover 30 so that the first contact portion 50 and the second contact portion 50. The upward movement range of the unit 60 may be limited. For this purpose, for example, the first protrusion 36 of the protrusion 35 may be omitted, and the entire protrusion 35 may have the same protrusion amount as the second protrusion 37. In addition, the regulation portion 33R of the cover 30 may be omitted.
