The operation member 62 is slidably fitted to the main body 24 and the blocking member 61, can move in the FB direction with respect to the main body 24 independently of the blocking member 61, and rotates around the main body 24. it can. Since the operation member 62 is exposed to the outside, the user can directly operate it. Since the blocking member 61 is covered with the operation member 62, the user cannot directly operate the blocking member 61.
The urging member 22 is, for example, a compression coil spring, and is arranged between the blocking member 61 and the main body 24 and configured to urge the blocking member 61 toward the F direction with respect to the main body 24.

As shown in FIG. 10, the main body 24 includes a first portion 441, a second portion 442, a third portion 443, and a fourth portion 444.
The first portion 441 is substantially cylindrical and fits inside the cylindrical portion 312 of the receptacle 13.

The fourth portion 444 has an outer diameter larger than that of the third portion 443 and larger than the outer diameter of the biasing member 22. Between the third portion 443 and the fourth portion 444, an annular planar step surface 448 is provided. The step surface 448 contacts the end of the biasing member 22 on the B side.

As illustrated in FIGS. 11 to 13, the operation member 62 includes a first portion 621 and a second portion 622.
The first portion 621 is substantially cylindrical and has an inner diameter larger than the outer diameter of the cylindrical portion 312 of the receptacle 13.
The second portion 622 has a substantially cylindrical shape and is located on the B side from the first portion 621. The second portion 622 has a larger inner diameter than the first portion 621 and slightly larger than the outer diameter of the fourth portion 444 of the main body 24. Between the first portion 621 and the second portion 622, an annular planar step surface 623 is provided.
The second portion 622 includes two guide portions 624 arranged symmetrically around the central axis of the operation member 62. The guide portion 624 is, for example, a groove that penetrates the side wall of the second portion 622, and guides the operation member 62 by engaging with the main body guide portion 45, thereby limiting the movable range of the operation member 62 relative to the main body 24. . The guide unit 624 includes, for example, a first guide groove 625 and a second guide groove 626. The second guide groove 626 is substantially parallel to the FB direction. When the main body guide portion 45 is engaged with the second guide groove 626, the operation member 62 can move in the FB direction with respect to the main body 24 within a predetermined range, but rotates around the main body 24. I can't. One end of the first guide groove 625 is connected to the end of the second guide groove 626 on the B side, and forms an angle θ with the second guide groove 626. The angle θ formed by the first guide groove 625 and the second guide groove 626 is an obtuse angle exceeding 90 degrees, for example, 100 degrees, or an arbitrary angle less than 180 degrees. When the main body guide portion 45 is engaged with the first guide groove 625, the operation member 62 can rotate around the main body 24 within a predetermined range, and in the FB direction with respect to the main body 24 along with the rotation. Moving.

As shown in FIGS. 14 and 15, the blocking member 61 includes a first portion 611 and a second portion 612.
The first portion 611 is substantially cylindrical and has an outer diameter larger than the inner diameter of the first portion 621 of the operating member 62, larger than the outer diameter of the biasing member 22, and larger than the inner diameter of the second portion 622 of the operating member 62. Slightly small. In the first portion 611, the end surface 614 on the F side can abut on the step surface 623 of the operation member 62. The first portion 611 has an inner diameter slightly larger than the outer diameter of the cylindrical portion 312 of the receptacle 13.
The second portion 612 has a substantially cylindrical shape and is located on the B side from the first portion 611. The second portion 612 has a slightly larger inner diameter than the outer diameter of the second portion 442 of the main body 24. In the second portion 612, the end surface 615 on the B side can abut on the step surface 447 of the main body 24. The second portion 612 has an outer diameter smaller than the inner diameter of the biasing member 22. Between the first portion 611 and the second portion 612, an annular planar step surface 613 is provided. The step surface 613 can come into contact with the F-side end of the urging member 22.
The blocking member 61 can move between a position where the end surface 614 contacts the step surface 623 and a position where the end surface 615 contacts the step surface 447. The movable range of the blocking member 61 is fixed on the B side, but varies on the F side depending on the position of the operation member 62. Since the blocking member 61 is urged toward the F direction by the urging member 22, the blocking member 61 is usually disposed at a position where the end surface 614 contacts the step surface 623. At this time, the urging force by the urging member 22 is transmitted to the operation member 62 via the blocking member 61 and urges the operation member 62 toward the F direction.

When assembling the plug 12, a main body 24 to which the main body guide portion 45 is not fixed is prepared. Next, the urging member 22, the blocking member 61, and the operation member 62 are sequentially fitted to the main body 24. Thereafter, the main body guide portion 45 is inserted into the guide portion 624 of the operation member 62 and fixed to the main body 24. As a result, the operation member 62 does not come off the main body 24, and the blocking member 61 and the biasing member 22 sandwiched between the operation member 62 and the main body 24 also do not come off.

When the operation member 62 is located at the holding position shown in FIGS. 16 and 17 with respect to the main body 24, the main body guide portion 45 of the main body 24 is engaged with the tip of the first guide groove 625 of the operation member 62. At this time, the operation member 62 can be rotated along the first guide groove 625 about an axis parallel to the FB direction. Since the first guide groove 625 forms an obtuse angle θ with respect to the FB direction, when the operation member 62 is rotated, the operation member 62 moves in the B direction accordingly. The closer the obtuse angle θ is to a right angle, the smaller the amount of movement of the operating member 62 in the B direction with rotation.
The blocking member 61 is biased by the biasing member 22, and the end surface 614 comes into contact with the step surface 623 of the operation member 62. The operation member 62 is urged in the F direction by the urging member 22 through the blocking member 61. Therefore, the operation member 62 does not rotate unintentionally due to vibration or the like, and is stabilized at the holding position.
In this state, the end surface 614 of the blocking member 61 is located on the F side with respect to the engaging portion 446 of the main body 24.

In this state, the user intentionally rotates the operation member 62 against the urging force of the urging member 22 to cause the operation member 62 to reach the first locking position shown in FIG. Can do. At this time, the operation member 62 and the blocking member 61 move in the B direction, but the end surface 614 of the blocking member 61 is not changed and is positioned on the F side with respect to the engaging portion 446 of the main body 24.
In this state, the main body guide portion 45 is engaged with a connection portion between the first guide groove 625 and the second guide groove 626. The operation member 62 can be moved in the B direction along the second guide groove 626. Since the operation member 62 is urged in the F direction by the urging member 22, the operation member 62 will not move in the B direction unless the user intentionally moves the operation member 62 in the B direction. Absent. The operation member 62 can also be rotated toward the holding position. The user may intentionally rotate the operation member 62 or simply release the operation member 62. When the obtuse angle formed by the first guide groove 625 and the FB direction is close to 90 degrees, the friction between the main body guide portion 45 and the inner side surface of the first guide groove 625 is simply released. The force may overcome the urging force by the urging member 22 and the operation member 62 may not rotate. Even in this case, if vibration or the like is applied, the operation member 62 rotates and finally reaches the holding position.

In this state, the user intentionally moves the operation member 62 in the B direction against the urging force of the urging member 22, thereby moving the operation member 62 to the first extraction position shown in FIGS. 19 and 20. Can be reached. As a result, the blocking member 61 moves in the B direction, and the end surface 614 is closer to the B side than the engaging portion 446 of the main body 24. This position of the blocking member 61 is referred to as a second removal position. On the other hand, the position where the end surface 614 is on the F side with respect to the engaging portion 446 is referred to as a second locking position. When the locking member 33 is engaged with the engaging portion 446, the blocking member 61 in the second locking position covers the locking member 33 from the outside, and the locking member 33 is prevented from coming off from the engaging portion 446. Stop. If the blocking member 61 is in the second extraction position, the movement of the locking member 33 is not hindered.
In this state, the main body guide portion 45 is engaged with the tip of the second guide groove 626. Since the operation member 62 is urged in the F direction by the urging member 22, when the user releases the operation member 62, the operation member 62 moves in the F direction and reaches the first locking position. To do.

To attach the plug 12 to the receptacle 13, first, the plug 12 is grasped and pushed into the receptacle 13 in the F direction. Even if the locking member 33 is located at the third locking position, the tapered surface 445 of the main body 24 abuts against the locking member 33 from the inside and pushes it outward, so that as shown in FIG. 33 moves to the third extraction position and protrudes outside the cylindrical portion 312.
When the plug 12 is further moved in the F direction, the locking member 33 comes into contact with the end surface 614 of the blocking member 61, so that the blocking member 61 cannot move in the F direction. Accordingly, as shown in FIG. 22, the blocking member 61 moves in the B direction relative to the main body 24 against the urging force of the urging member 22. Since the blocking member 61 can move independently of the operation member 62, even if the operation member 62 is gripped, the relative movement of the blocking member 61 is not disturbed.
When the plug 12 is further moved in the F direction, the blocking member 61 reaches the second extraction position. Since the engaging portion 446 is provided, the locking member 33 can move inward. The urging force of the urging member 22 is transmitted to the locking member 33 via the blocking member 61, the locking member 33 moves to the third locking position, protrudes to the inside of the cylindrical portion 312, and moves to the engaging portion 446. Engage. Since the blocking member 61 has nothing to obstruct the movement in the F direction, it reaches the second locking position. Accordingly, as shown in FIG. 23, the locking member 33 is held at the third locking position, and the engagement between the locking member 33 and the engaging portion 446 cannot be released. In this way, the attachment of the plug 12 to the receptacle 13 is completed.
Thus, the operation member 62 does not need to move with respect to the main body 24 at the time of mounting. Therefore, the plug 12 can be securely fitted to the receptacle 13 no matter what part of the plug 12 is gripped. The operation member 62 may be in the holding position, and it is not necessary to rotate the operation member 62.

To remove the plug 12 from the receptacle 13, when the operation member 62 is in the holding position, the operation member 62 is grasped and rotated to the first locking position. Then, the plug 12 is pulled in the B direction while holding the operating member 62 at the first locking position. Since the locking member 33 is engaged with the engaging portion 446, the main body 24 cannot move. The step surface 623 of the operation member 62 contacts the end surface 614 of the blocking member 61, and the blocking member 61 moves in the B direction together with the operating member 62. As a result, the operation member 62 and the blocking member 61 move relative to the main body 24 in the B direction.
As shown in FIG. 24, when the operation member 62 reaches the first extraction position, the blocking member 61 reaches the second extraction position, and the locking member 33 can move outward, and reaches the third extraction position. To reach. Thereby, the engagement between the locking member 33 and the engaging portion 446 is released, and the main body 24 can move in the B direction as shown in FIG.
When the operating member 62 is held and pulled further in the B direction, the main body 24 moves in the B direction together with the blocking member 61 as shown in FIG. In this way, the plug 12 is removed from the receptacle 13. The force applied to the operation member 62 may be transmitted to the main body 24 when the step surface 447 abuts on the end surface 615 of the blocking member 61, or the main body guide portion 45 is applied to the tip of the second guide groove 626. It may be transmitted by abutting or may be transmitted via the urging member 22.
As described above, the plug 12 can be easily removed from the receptacle 13 by grasping the operation member 62 at the time of removal. Even if a portion other than the operation member 62 is gripped, the blocking member 61 does not move to the second removal position, so that the plug 12 cannot be removed from the receptacle 13. Further, even if the operation member 62 in the holding position is pulled without being rotated, the operation member 62 cannot reach the first removal position unless it passes through the first locking position, so that the plug 12 is removed from the receptacle 13. I can't.
