It can be extended from the converter, and the cylindrical plug body 2 is used by connecting it to a jack pre-installed on an electronic device, but if the power cord 3 is
- Although the cylindrical plug body 2 is designed to extend beyond the DC converter, the conductive sleeve 6 of the cylindrical plug body 2 is exposed to the outside when the cylindrical plug body 2 is not connected to a jack installed in an electronic device. As a result, there is a risk of electric shock due to contact with this, and the conductive sleeve 6 of the cylindrical plug body 2 is exposed to the outside, and the conductive sleeve 7 is exposed to the outside.
Since the conductive sleeves 6 and 7 are open to the outside, there is a risk that the conductive sleeves 6 and 7 may be inadvertently short-circuited with a conductive piece, etc., and the AC-DC converter may generate heat. This was problematic from a gender perspective. Furthermore, since the conductive sleeve 7 of the cylindrical plug main body 2 is open to the outside, dust tends to accumulate inside the conductive sleeve 7, deteriorating its function as a plug.

外すのに邪魔となることがない。 The above is an example of the configuration of the corded power plug 21 according to the present invention. According to such a configuration, it can be operated on a DC power source like the conventional corded power plug 1 described above in FIG. It is clear that it can be used to supply electronic equipment with DC power obtained from an AC-DC converter that converts commercial AC power into DC power, but the corded power plug 1 shown in Fig. 1 above It has a flexible crown body 22 and a connecting flexible linear or band-like body 23 that can be extended between the flexible crown body 22 and the gripping part 4, and the flexible crown body 22 is connected to the cylindrical plug body 2. 4, the conductive sleeve 6 of the cylindrical plug main body 2 is inserted into the annular portion 24a, and the plug-shaped body 25 is fitted into the conductive sleeve 7, as shown in FIG. The power cord 3 becomes AC-DC.
Although the cylindrical plug body 2 is designed to extend beyond the converter, when the cylindrical plug body 2 is not connected to a jack installed in an electronic device and is not in use, the flexible crown body 22 can be attached to the cylindrical plug body 2 as described above. In other words, since the conductive sleeve 6 of the cylindrical plug body 2 is not exposed to the outside, there is no risk of electric shock due to contact with the conductive sleeve 6, and the cylindrical plug body 2
Since the conductive sleeve 6 is not exposed to the outside, and the conductive sleeve 7 is not opened to the outside,
The conductive sleeves 6 and 7 are not inadvertently short-circuited by a conductive piece, etc., and therefore AC-DC
The converter does not have the appearance of generating heat. Therefore, there is no problem in terms of safety. Furthermore, since the conductive sleeve 7 of the cylindrical plug main body 2 is not open to the outside, there is no risk of dust accumulating inside the conductive sleeve 7 and deteriorating its function as a plug.
Further, the flexible crown body 22 has flexibility, and the conductive sleeve 6 of the cylindrical plug main body 2 is inserted into the annular portion 24a thereof, and the plug-like body 25 is inserted into the conductive sleeve 7. Therefore, once the flexible crown body 22 is attached to the cylindrical plug body 2, it will not fall off from the cylindrical plug body 2 inadvertently. This ensures that the state in which it is attached to the main body 2 is maintained. Also, flexible crown body 22
is connected to the grip part 4 via the connecting flexible linear or band-like body 23, so there is no chance that the flexible crown 22 will be lost. Since the band-like body 23 is flexible, it does not become an obstacle when the flexible crown body 22 is mounted on or removed from the cylindrical plug body 2.

する。 Further, the corded power plug 1 can be constructed by embedding the cylindrical plug body 2 and the power cord 3 with an insulating material to construct the grip portion 4. When constructing the corded power plug 1, the flexible crown body 22 and the connecting flexible linear or band-shaped body 23 can be constructed at the same time, so that the corded power plug 1,
The structure consisting of the flexible crown body 22 and the connecting flexible linear or band-shaped body 23 can be easily integrated as one component, and the corded power plug 1 and its flexible Since the structure consisting of the elastic crown body 22 and the connecting flexible linear or band-like body 23 is integrated as one component, it is easy to handle, and as mentioned above, it is flexible. It has the characteristics that the crown body 22 does not become powdery.

易になるものである。 Furthermore, a slit 2 is formed in the annular portion 24a of the flexible crown body 22.
4d makes it easier to mount and remove the flexible crown 22 from the cylindrical plug body 2.
