DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described.

FIG. 1 is an exploded perspective view showing a use state of a power cable disconnection prevention device 1 according to an embodiment of the present invention. As shown in FIG. 1, the power cable disconnection prevention device 1 includes a housing 2 and the like. The housing 2 has upper and lower 2
It consists of an upper housing 3 and a lower housing 4 which are separated into two. The upper housing 3 and the lower housing 4 can be fixed to each other so as to be sandwiched from the base portion 6 of the power cable 5 of the electric / electronic device to the power plug 7.

That is, the upper casing 3 and the lower casing 4 are shaped so as to fit when they are overlapped with each other. Holes 8 and 8 having the same shape are formed in the upper housing 3, and claws 9 and 9 having the same shape are formed in the lower housing 4. The upper housing 3 and the lower housing 4 are overlapped. Sometimes, the hole 8 and the claw 9 are fitted. Screw holes 10, 10 pass through the upper housing 3, and screw insertion portions 11, 11 are also formed in the lower housing 4 so as to protrude upward from the inner bottom surface. The screw insertion portions 11 and 11 have holes through which screws are inserted. The upper housing 3 and the lower housing 4 are overlapped, a screw 12 is inserted from the screw hole 10 to the hole of the screw insertion portion 11, and the upper housing 3 and the lower housing are screwed by the screw 12 and the nut 13. 4
Can be tightened and fixed.

By overlapping the upper housing 3 and the lower housing 4, the housing 2 is formed with a power plug receiving portion 14 for accommodating a base end portion of the power plug 7. In addition, the power cable insertion holes 15 and 16 are formed in the housing 2 by overlapping the upper housing 3 and the lower housing 4. The upper housing 3 and the lower housing 4 are overlapped with each other so as to be sandwiched between the upper housing 3 and the lower housing 4 from the base portion 6 of the power cable 5 to the power plug 7, and are fixed by screws as described above. The base end portion of the power plug 7 can be housed and fixed in the power plug receiving portion 14.
In addition, the base portion 6 of the power cable 5 is bent by contacting the screw insertion portion 11 so that the power cable 5 follows a predetermined path and exits the housing 2 from the power cable insertion hole 15 or 16. be able to. As a result, the base end portion of the power plug 7 is fixed in the power plug receiving portion 14 and the root portion 6 of the power cable 5 is supported by the screw insertion portion 11 and the power cable insertion hole 15 or 16. Is fixed to the power plug 7 while being bent in a certain direction. More specifically, the root portion 6 of the power cable 5 is located on the horizontal side with respect to the power plug 7 inserted into the outlet 17, that is, on the right side when the power cable 5 comes out from the power cable insertion hole 15. When the power cable 5 comes out of the cable insertion hole 16, it is bent to the left. A flat portion 22 is formed on the side of the housing 2 opposite to the side on which the power plug 7 is fixed.

As shown in FIG. 2, the power plug receiving portions 14 of the upper housing 3 and the lower housing 4 are engaged with the teeth 18 formed at the base end of the power plug 7 so as to be connected to the power plug. A mountain tooth 19 which is an engaging portion for fixing the fixing member 7 is formed.

According to the power cable disconnection preventing device 1 having the above-described configuration, even if the power plug 7 is inserted into the outlet 17, the power cable 5 is hard to pop out, so that the chances of catching a limb on the power cable 5 are reduced. In addition, the occurrence of disconnection at the root portion 6 of the power cable 5 can be suppressed. Further, when the power plug 7 is inserted into the outlet 17, the horizontal side of the housing 2 (right side or left side)
When the facility is extended horizontally, the person does not get caught on the power cable 5 and the disconnection at the base 6 of the power cable 5 is suppressed. can do.

The attachment of the power cable disconnection preventing device 1 is performed only by fixing the upper housing 3 and the lower housing 4 constituting the housing 2 to each other so as to sandwich the power cable 5 from the base 6 to the power plug 7. This can be easily performed even when the power plug 7 is inserted into the outlet 17.

The power teeth 7 are engaged with the mountain teeth 18 formed at the base end of the power plug 7 to fix the power plug 7, so that the power plug 7 is prevented from coming off.

As is clear from FIG. 1, the power cable 5
When the flat portion 22 is pressed with the power cable disconnection prevention tool 1 fixed from the base portion 6 to the power plug 7, all the pressing force is applied to the power plug 7,
The pressing force allows the power plug 7 to be inserted into the outlet 17. Therefore, even if the flat portion 22 is pressed, the pressing force is not applied to the power cable 5.
The power plug 7 can be inserted into the outlet 17 without damaging the power cable 5.

As shown in FIGS. 3 and 4, the power plug 7 is fixed in the power plug receiving portion 14 by elastically contacting the base end of the power plug 7 instead of the tooth 19. An elastic member such as a rubber 20 (see FIG. 3) or a leaf spring 21 (see FIG. 4) may be formed.

If the elastic member is formed in the power plug receiving portion 14 in this manner, the power plug 7 can be fixed by abutting the elastic member on the power plug 7. In addition, the power cable disconnection preventing device 1 can be attached to some extent to various shapes and sizes of the power plug 7.

[0032]

According to the first aspect of the present invention, it is possible to make it difficult for the power cable to jump out, so that the chance of a person getting caught on the power cable is reduced, and disconnection at the root of the power cable is suppressed. be able to.

According to a second aspect of the present invention, in the power supply cable disconnection prevention device according to the first aspect, the two parts constituting the housing are fixed to each other so as to be sandwiched from the base of the power supply cable to the power supply plug. , So that it can be easily installed with the power plug inserted into the outlet.

According to a third aspect of the present invention, in the power supply cable disconnection prevention device according to the first or second aspect, in the case of a power supply cable that is extended in a horizontal direction and installed, a person may be caught on the power supply cable. Opportunities can be reduced, and disconnection at the root of the power cable can be suppressed.

According to a fourth aspect of the present invention, in the power supply cable disconnection preventing device according to any one of the first to third aspects, the power plug is fixed by engaging the engaging member with the toothed portion. So that the power plug is prevented from coming off.

According to a fifth aspect of the present invention, in the power supply cable disconnection preventing device according to any one of the first to third aspects, the power plug can be fixed by abutting the elastic member on the power plug. Therefore, due to the play caused by the elastic deformation of the elastic member, it is possible to attach the power plug to various shapes and sizes to some extent.

According to a sixth aspect of the present invention, in the power cable disconnection preventive device according to any one of the first to fifth aspects, even if a flat portion is pressed, the pressing force is not applied to the power cable. Therefore, the power plug can be inserted into the outlet without damaging the power cable.
