The dimension (first dimension) of the first base portion 410 in the axial direction is equal to or greater than the thickness of the metal plate. The dimension (second dimension) of the second base portion 420 in the axial direction is equal to or greater than the thickness of the metal plate. In particular, the first base portion 410 and the second base portion 420 of the present embodiment have the same size in the axial direction. That is, the first size and the second size are equal to each other. However, the present invention is not limited thereto, and the first base portion 410 and the second base portion 420 may have different sizes from each other.

As shown in FIGS. 12 to 14 , the first spring portion 430 and the second spring portion 440 are alternately arranged at intervals in the circumferential direction.

As shown in FIGS. 12 to 14 , each of the first spring portions 430 connects the first base portion 410 and the second base portion 420 . 4 to 6 and 12 to 14 , it can be understood that each of the first spring portions 430 has a first contact 435, and the first contact 435 is fitted to the adapter 300 at the first connector 100.

In the axial direction, the end portion of the terminal that constitutes the first slit 640 (that is, the end portion close to the second end portion 620) is used as a function of the first baffle 645, which will be described later. Similarly, the end portion of the terminal that constitutes the second slit 650 (that is, the end portion close to the first end portion 610) is used as a function of the second baffle 655 to be described later in the axial direction.

The portion sandwiched between the first slits 640 functions as a spring portion that elastically supports the first end portion 610, and the portion sandwiched between the second slits 650 serves as an elastic support for the second end portion. The function of the spring part of the 620 is used. With these spring portions, the first end portion 610 or the second end portion 620 can be moved in the radial direction, that is, elastically deformed.

In the present embodiment, the number of the first slits 640 is equal to the number of the second slits 650, and the first slits 640 and the second slits 650 are alternately arranged in the circumferential direction around the axial direction. Further, the first slit 640 and the second slit 650 partially overlap each other in the axial direction. As a result, a part of the second slit 650 is formed in the spring portion supporting the first end portion 610, and a part of the first slit 640 is formed in the spring portion supporting the second end portion 620. With such a configuration, it is possible to reduce the axial dimension of the external pin 600 and form a relatively long slit to obtain a spring having a long spring length. Specifically, in the present embodiment, the size of the first slit 640 is larger than half the size of the external pin 600 in the axial direction, and the size of the second slit 650 is larger than half the size of the external pin 600. Since it is large, even if the size of the external pin 600 is small, the length of the spring supporting the spring portion of the first end portion 610 and the second end portion 620 can be increased.

The external pin 600 having the above-described configuration is attached to the outer periphery of the insulating member 500 by inserting the insulating member 500 into the external pin 600. in At the time of this mounting, since the first inclined surface 534 of the first projection 530 or the second inclined surface 544 of the second projection 540 is provided, the insulating member 500 can be easily inserted into the external pin 600. As a result of the mounting, the first protrusion 530 is housed in the first slit 640, and the second protrusion 540 is housed in the second slit 650.

Specifically, referring to Fig. 11, the first opposing surface 532 of the first projection 530 faces the first flap 645 in the axial direction, and the second opposing surface 542 of the second projection 540 faces the second stop in the axial direction. Board 655. Further, in the axial direction, the first opposing surface 532 is located between the first inclined surface 534 and the first baffle 645, and the second opposing surface 542 is located between the second inclined surface 544 and the second baffle 655 in the axial direction. Further, the first baffle 645 is located between the first slit 640 and the second end portion 620, and the second baffle 655 is located between the second slit 650 and the first end portion 610.

Further, as shown in Fig. 12, the small diameter portion 520 is provided at both ends of the large diameter portion 510 in the axial direction. Therefore, as shown in Fig. 10, the first end portion 610 and the second end portion 620 are formed radially inward. There is space. Therefore, the first end portion 610 or the second end portion 620 can move inward in the radial direction.

As can be understood from Fig. 2, in a state in which the adapter 300 is fitted to the second connector 200, the main portion 630 of the external pin 600 is located at a position separated from the second outer conductor 230 in the radial direction. Therefore, the adapter 300 can be moved in a plane perpendicular to the axial direction by the spring characteristics of the external connector 600. That is, the adapter 300 is floatingly supported by the second connector 200. When the adapter 300 that is floatingly supported by the second connector 200 is fitted into the first connector 100 as described above, the first end portion 610 is guided by the guide portion 132 and is appropriately housed in the first outer conductor 130. . Therefore, it can be understood from FIGS. 4 to 6 that when the first circuit board 700 faces the second circuit board 750, the positions of the first connector 100 and the adapter 300 are slightly biased. The difference between the two connectors can be appropriately fitted to the rotary machine 300 without visually observing the fitting positions of the two.

As shown in FIG. 4, in a state where the first connector 100 and the second connector 200 are connected to each other through the adapter 300, the main portion 630 of the external pin 600 is separated from the first outer conductor 130 in the radial direction. position. As can be understood from FIG. 4, the first outer conductor 130 of the first connector 100 and the external pin 600 of the adapter 300 are connected only at the position of the first end portion 610, and the second outer conductor 230 of the second connector 200 is connected. The external pin 600 of the adapter 300 is connected only at the position of the second end portion 620.

As shown in FIGS. 4 to 6 , in a state where the first connector 100 and the second connector 200 are connected to each other through the adapter 300, the installation of the guide portion 132 does not directly contact the second outer conductor 230. In particular, in the present embodiment, when the first connector 100 and the second connector 200 are connected to each other through the adapter 300, the first end portion 610 of the adapter 300 and the insulation are in a design reference state. The space 500 exists between the member 500 and the first holding member 120 of the first connector 100. Therefore, even if the distance between the first circuit board 700 and the second circuit board 750 (the distance between the substrates) is slightly changed, the space S can absorb the fluctuation. In the present embodiment, even when the distance between the substrates is the shortest, that is, when the first end portion 610 of the adapter 300 or the insulating member 500 abuts against the first holding member 120 of the first connector 100 and the space S disappears, The guide portion 132 still does not directly contact the second outer conductor 230. Therefore, even when the distance between the substrates is the smallest, the first connector 100 and the second connector 200 can be absorbed in the plane perpendicular to the axial direction, and the first connector can be surely connected through the adapter 300. 100 and the second connector 200.

As shown in FIGS. 4 to 6, the second end portion 620 is embedded in the adapter 300. In the state of the second connector 200, the locking portion 234 of the second outer conductor 230 is locked. On the other hand, as described above, the first connector 100 is not provided with a portion such as the locking portion 234. Therefore, when the first connector 100 fixed to the first circuit board 700 and the second connector 200 fixed to the second circuit board 750 are connected to each other through the connector 300, the first circuit board 700 and the second board are connected. The circuit board 750 moves in the direction in which the circuit board 750 is separated from each other, and the fitting of the adapter 300 and the second connector 200 is continued, and the first connector 100 is detached from the adapter 300. At this time, the second flap 655 (see FIG. 11) abuts against the second opposing surface 542, thereby preventing the insulating member 500 from coming off the external pin 600.

Although the embodiments of the present invention have been specifically described above, the present invention is not limited thereto, and various modifications are possible. For example, the guide portion 132 shown in Fig. 1 is a state in which the end portion of the first outer conductor 130 is notched and expanded. However, the present invention is not limited thereto, and the shear deformation may be formed by cutting. After the end portion, the first outer conductor 130 is formed by being rolled into a cylindrical shape, thereby forming a guide portion having no slit.
