FIG. 5 is an explanatory view showing a state in which a plug is connected to the socket.
[0017]
1 and 2 show the entire socket 1 and plug 2. In the socket 1, a cylindrical shell 5 having a cable 4 connected to an end portion is formed with a small diameter on the connection portion side (front end side) with the plug 2. A hollow rotating member 7 is attached. The narrow-diameter portion 6 is formed with a groove portion 8 in a circumferential shape on the proximal end side, while the rotating member 7 is formed with a hook portion 9 at a position facing the groove portion 8, and the rotating member 7 has the hook portion 9. It is freely rotatable with respect to the socket long axis while being engaged with the groove 8.
[0018]
The tip of the small-diameter portion 6 is formed to be slightly thicker by a half circumference, and the peripheral portion of the large-diameter portion 10 constitutes the engaging claw 11. On the front surface of the large-diameter portion 10 on which the engaging claws 11 are formed, an electrode surface 13 is provided in which a plurality of electrodes 12 are exposed. The electrode 12 is connected to a signal line (not shown) in the cable 4.
[0019]
In the present embodiment, a wiping member 14 is provided on the front surface of a semicircular portion that is not formed in the large diameter at the tip of the small diameter portion 6. The wiping member 14 is made of a material capable of wiping off moisture adhering to the electrode 26 and the electrode surface 25 on the plug 2 side which will be described later.
[0020]
The rotating member 7 is a cylindrical member whose front end surface is opened by a half circumference (opening 15). The remaining half-peripheral portion that is not open on the distal end side of the rotating member 7 is formed to have a predetermined thickness in the socket major axis direction and constitutes a wiping member mounting portion 16. A wiping member 17 is attached to the surface of the wiping member mounting portion 16 facing the electrode surface 13.
[0021]
The wiping member 17 is made of a material capable of wiping off moisture adhering to the electrode 12 and the electrode surface 13, and the wiping member mounting portion 16 can contact the electrode surface 13 and the electrode 12.
[0022]
On the other hand, the plug 2 has a cylindrical shell 22 with a cable 21 connected to the rear end. The shell 22 has a convex portion 23 as an engaging convex member formed in a semi-cylindrical shape with a small diameter on the connection portion side (tip side) with the socket 1. The shape of the convex portion 23 seen from the plug major axis direction (B direction) matches the shape of the opening 15 at the tip of the rotary member 7 of the socket 1, and the convex portion 23 is inserted into the rotary member 7 from the opening 15. It is possible.
[0023]
On the distal end side of the convex portion 23, the center side in the radial direction is a cavity, and the electrode 26 is exposed at the distal end surface (electrode surface 25) of the convex portion 23 in the hollow portion 24. The electrode 26 is connected to a signal line (not shown) in the cable 21. An engaging portion 27 is formed at the tip of the convex portion 23 of the cavity portion 24. In the cavity 24, a groove 28 is formed in a circumferential shape on the inner periphery on the electrode surface 25 side.
[0024]
The length from the base end of the convex part 23 to the electrode surface 25 of the convex part 23, the length of the engaging part 27, the width of the groove 28, the depth of the groove 28, etc. are set according to the shape of each part of the socket 1. ing. That is, the length from the base end of the convex part 23 to the electrode surface 25 of the convex part 23 is substantially equal to the length of the wiping member attaching part 16 of the rotating member 7. Thus, the electrode 26 comes into contact with the wiping member 14 in a state where the plug 2 is inserted into the socket 1 until the base end surface of the convex portion 23 comes into contact with the distal end surface of the rotating member 7.
[0025]
Further, the length of the engaging portion 27 and the width of the groove 28 are such that the front end side surface of the groove 28 and the back surface (base end) of the engaging claw 11 in a state where the base end surface of the convex portion 23 is in contact with the front surface of the rotating member 7 (Side plane). The inner diameter of the cavity portion 24 is larger than the outer diameter of the small diameter portion 6 and smaller than the outer diameter of the engaging claw 11. The inner diameter of the groove 28 is slightly larger than the outer diameter of the engaging claw 11.
[0026]
Therefore, in the present embodiment, the convex portion 23 of the plug 2 can be completely inserted into the rotating member 7 of the socket 1 in a state where the wiping member 14 faces the opening 15 of the rotating member 7. Further, in this state, the rotating member 7 can be rotated together with the plug 2 with respect to the socket long axis.
[0027]
Next, the operation of the embodiment configured as described above will be described.
