2. Description of the Related Art In general, in electronic devices and various devices such as a vehicle-mounted wireless device in which an operation unit and a radio unit are separated, a connection cable for connecting a main body of the electronic device and other devices and devices. Is used. In an electronic device or the like using such a connection cable, a cable for pulling out and fixing the connection cable is usually provided so that the other end of the connection cable can be pulled out and fixed in a desired direction in which another device or the like is located. It has a drawer structure.

FIG. 5 shows a conventional connection cable lead-out structure of this type. FIG. 5A is a partial cross-sectional side view of an electronic device to which cables are connected and fixed by the cable lead-out structure. () Is a rear view.

As shown in these figures, a conventional connection cable lead-out structure includes a cable lead-out port 23 provided on the back of an electronic device main body 21 and a cable lead-out port 23 at one end.
A connection cable 22 that is connected to the electronic device main body 21 through the other end and that is drawn out of the electronic device from the cable outlet 23 at the other end thereof;
2 is provided with a cap 25 for pulling out the other end side in a desired direction, and holding and fixing this along the electronic device body 21.

[0005] The cap 25 is a housing-like member that is large enough to cover the cable outlet 23 of the electronic device main body 21 and is opened on the cable outlet side. As shown in FIG. The cable 25 is fixed to the electronic device main body 21 by screwing, and covers the cable outlet 23. On one side of the cap 25, that is, on the side where the cable is pulled out, a cutout portion 26 is formed with substantially the same diameter as the connection cable 22 so that the connection cable 22 can be pulled out. A claw 2 is provided on the inner wall side of the cap 25.
4 are protrudingly provided so that the connection cable 22 can be held by penetrating into the jacket of the connection cable 22.

According to such a conventional connection cable lead-out structure, the connection cable 22 pulled out of the electronic device main body 21 is directed by the cap 25 in one desired direction in which another electronic device (not shown) is located. And is held and fixed along the back surface of the electronic device main body 21 and the like. Thus, the connection cable 22 does not hinder a person, a machine, an instrument, or the like passing near the electronic device main body 21, and even if a person or an object accidentally contacts the connection cable 22, the connection cable 22 is disconnected from the electronic device main body 21. It can be connected to other electronic devices without falling off.

However, in such a conventional connection cable pull-out structure, since the connection cable is held and fixed by the cap, the pull-out direction of the connection cable is uniquely determined by the shape and mounting position of the cap. The drawer direction cannot be arbitrarily selected or changed. For this reason, there is a problem that the installation location of the electronic device is restricted by the connection cable lead-out structure depending on the relationship between the location and the installation location of other devices and devices.

Therefore, in order to solve the problem of such a conventional connecting cable lead-out structure, Japanese Utility Model 2-2 has been proposed.
Japanese Patent No. 7511 proposes a small plug in which the direction in which the connection cable is pulled out can be arbitrarily determined and changed, and the wire pulling direction is variable. 6 and 7 show a small plug in which the electric wire drawing direction is variable described in Japanese Utility Model Publication No. 2-27511, and FIG. 6A is a perspective view showing an assembled state of the small plug. (B) is a perspective view of the disassembled state of the small plug, and FIG. 7 is a perspective view of the state where the small plug is attached to the electronic device body.

As shown in these figures, this small plug of which the electric wire drawing direction is variable is a connection terminal 30 which is connected to an electronic device main body 31 as a whole, and a plug to which a cable 32 is connected to form a plug. A plug body 33 including a piece 34 and a circular base 35 for holding the plug piece 34; a cylindrical cap 36 rotatably engaged with the base 35 of the plug body 33; Cable 3 that engages with the end on the base 35 side
2 is provided with a bushing 37 for holding the same.

As shown in FIG. 6 (b), the bushing 37 has a cylindrical shape through which the cable 32 can pass through at the center in the axial direction. A groove 38 is formed. As a result, the bushing 37 is attached to the side of the cap 36 in a rotatable state in a direction orthogonal to the axial direction of the cap 36.

According to the small-sized plug having the above configuration, the cable 32 can be connected to the plug main body 33 through the bushing 37 which is rotatable in a direction perpendicular to the plug piece 34. The direction can be directed to an arbitrary direction on a plane orthogonal to the connection direction of the terminals. Thus, other component arrangement on the terminal connection surface of the electronic device main body 31 can be freely selected, and the installation location of the electronic device itself can be freely determined without being limited by the position of the other electronic device. You can choose.

[0012]

However, the small plug of Japanese Utility Model Publication No. 2-27511 in which the electric wire withdrawal direction is variable can pull out the connection cable in an arbitrary direction with respect to the electronic device main body. No connection preventing means or the like is provided for the connection portion between the plug and the plug. For this reason, when a person or an object accidentally comes into contact with a cable or a terminal pulled out from the electronic device main body, there is a problem that the cable or the terminal is pulled out from the electronic device.

The present invention has been proposed in order to solve such a problem of the conventional technology, and can arbitrarily determine and change the drawing direction of a connection cable connected to an electronic device or the like. It is another object of the present invention to provide a connection cable lead-out structure for holding a connection cable pulled out in a desired direction simply, reliably, and firmly to prevent the connection cable from dropping from an electronic device or the like.
