Further, when the rotating member 13 rotates 90 ° between the open position and the fixed position as in the present embodiment, the amount of rotation of the rotating member 13 can be suppressed to be small, so that the workability at the time of assembly is further improved. ..

Further, in the present embodiment, the first rotation restricting unit 16 restricts the rotating member 13 at the fixed position from rotating further. Therefore, the assembly work is easy to perform. Further, the rotating member 13 is stably maintained at a fixed position.

Further, in the present embodiment, the first substrate 1 and the second substrate 2 can be more stably fixed by the support portions 12 and the rotating members 13 provided with the connector terminal portion 11 interposed therebetween.

Further, in the present embodiment, the second rotation suppressing portion 15 suppresses the rotation of the rotating member 13 from the open position to the fixed position.

Further, in the present embodiment, when the terminal portion 2c of the second substrate 2 is connected to the connector terminal portion 11, the second end portion 13b of the rotating member 13 is fitted into the notch portion 2d. In other words, by aligning the second end portion 13b of the rotating member 13 and the notch portion 2d, the connector terminal portion 11 of the first substrate 1 and the terminal portion 2c of the second substrate 2 can be easily aligned. .. Therefore, workability at the time of assembly is further improved.

Further, in the present embodiment, the rotating member 13 set to the open position is stably maintained in the open position by the second rotation regulation unit 24. Therefore, the rotating member 13 can be easily moved from the open position to the fixed position, and the assembly work can be easily performed.

Further, in the present embodiment, the movement suppressing portion having the large inner diameter portion 17a and the second large diameter portion 22 suppresses the movement of the rotating member 13 with respect to the support portion 12 and the first substrate 1 in the vertical direction. Therefore, regardless of the position and posture of the rotating member 13, the rotating member 13 is stably supported by the support portion 12, and the rotating member 13 is prevented from coming out of the support portion 12.

FIG. 8 shows a connector unit 10 of a modified example of this embodiment. In this modification, the rotating member 13 is removable from the support portion 12. In the case of this modification, the rotating member 13 may be made of resin, for example.

In this modification, the support portion 12 has an opening 26 that penetrates a part of the tubular portion 17 in the circumferential direction in the radial direction. The opening 26 penetrates a part of the tubular portion 17 in the circumferential direction substantially in the front-rear direction. The opening 26 is arranged in the support portion 12 over the entire length in the axial direction. The tubular portion 17 can be elastically deformed so as to increase the length (opening width) of the opening 26 in the circumferential direction. The rotating member 13 is inserted into the tubular portion 17 through the opening 26 by elastically deforming the tubular portion 17. The rotating member 13 inserted into the tubular portion 17 can pass through the opening 26 when an external force of a predetermined value or more is applied to the rotating member 13 in the radial direction. In other words, the rotating member 13 inserted into the tubular portion 17 cannot pass through the opening 26 even if an external force less than a predetermined value is applied to the rotating member 13 in the radial direction.

The opening 26 has a small diameter receiving portion 26a and a large diameter receiving portion 26b.
The small diameter receiving portion 26a is arranged in a portion of the opening 26 other than the lower end portion. The length (opening width) of the small diameter receiving portion 26a in the circumferential direction is smaller than the outer diameter of the small diameter portion 19 of the rotating member 13.
The large diameter receiving portion 26b is arranged at the lower end portion of the opening 26. The length (opening width) of the large-diameter receiving portion 26b in the circumferential direction is smaller than the outer diameter of the second large-diameter portion 22 of the rotating member 13.

In this modification, a third rotation restraining unit 25 is provided instead of the second rotation restricting unit 24.
The third rotation suppressing portion 25 suppresses the rotating member 13 in the open position from rotating in the circumferential direction around the central axis C in the direction opposite to the fixed position. The third rotation suppressing portion 25 has a third protrusion 25a and a riding over portion 14b.

The third protrusion 25a is provided on either the support portion 12 or the rotating member 13. In this modification, the third protrusion 25a is provided on the support portion 12. The third protrusion 25a protrudes in the axial direction. The third protrusion 25a projects upward from the upper end surface of the cylinder 17.

The overcoming portion 14b is provided on either one of the support portion 12 and the rotating member 13, and can get over the third protrusion 25a from the circumferential direction around the central axis C. In this modification, the overpass portion 14b is provided on the rotating member 13. The rotation locus obtained by rotating the overpass portion 14b around the central axis C interferes with the third protrusion 25a.
When the rotating member 13 is in the open position, the overpass portion 14b is arranged so as to be sandwiched between the second protrusion 15a and the third protrusion 25a in the circumferential direction.

According to this modification, since the rotating member 13 can be attached to and detached from the supporting portion 12, the supporting portion 12 and the rotating member 13 can be assembled after being manufactured in a separate step. Therefore, the degree of freedom in the manufacturing method of the connector unit 10 is increased. For example, the support portion 12 and the rotating member 13 can be separately molded and assembled from different resin materials.
