Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for holding a power cord in equipment that uses commercial power, such as office equipment.

Generally, in this type of equipment, the power cord is led out of the equipment body through the side wall of the equipment body, and the method of holding the power cord is as shown in Figs. 1 and 2. A holder 2 integrally formed with the power cord 1 is inserted into a cutout recess 4 provided at the upper end of the lower case 3, and the holder 2 is inserted into the upper case 5 as shown in FIG.
As shown in FIGS. 3 and 4, the threaded part 6a of the pipe-shaped holder 6 is inserted into the hole 7a provided in the lower case 7, and Tighten the nut 8 to fix the pipe-shaped holder 6, then pass the power cord 1 through the hole 8a of the nut 8, the hole 7a of the lower case 7, and the hole 6b of the pipe-shaped holder 6, and tighten the power cord with the screw 9. 1 is generally adopted, but when exporting this type of equipment to a foreign country, the standards for how to hold the power cord 1 differ depending on the country, so manufacturers have to fix the power cord 1 in each country. In order to comply with the standards for the holding method in No. 1, it was necessary to manufacture the two types of lower cases 3 and 7, which was extremely unreasonable in terms of cost.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to make it possible to share the lower case.

The basic structure of the present invention for achieving the above object is that when a power cord is held by tightening a nut on the threaded part of a pipe-shaped holder through which the power cord is inserted, a separately provided fixing member is used. In this case, the power cord is held in the fixing member, and the fixing member is inserted into the notch provided at the upper end of the lower case, and the fixing member is clamped between the upper case and fixed. It is.

With the above configuration, the present invention makes it possible to utilize the notch recess of the lower case when clamping and fixing the holder integrally formed with the power cord between the lower case and the upper case. Only a few types of cases can be used, and as a result, a very advantageous cost advantage can be obtained.

Hereinafter, one embodiment of the present invention will be described based on the accompanying drawings. When fixing the holder integrally formed with the power cord between the lower case and the upper case, as shown in Figures 1 and 2, the holder must be integrally molded with the power cord 1. The formed holder 2 is inserted into the notched recess 4 provided at the upper end of the lower case 3, and as shown in FIG. 1, the holder 2 is clamped and fixed by the upper case 5. In addition, when holding the power cord in the lower case by tightening a nut on the threaded part of the pipe-shaped holder 6 through which the power cord is inserted, as shown in Figs. The separate fixing member 10 is fixed to the pipe-shaped holder 6 by inserting the part 6a into the hole 10a of the separately provided fixing member 10 and tightening the nut 8 on the threaded part 6a, and then tightening the power cord 1 into the nut. 8, hole 10a of fixing member 10, and hole 6 of pipe-shaped holder 6.
a and fix the power cord 1 with screw 9,
Furthermore, after that, the fixing member 10 is inserted into the notch recess 4 of the case 3, and as shown in FIG.
The fixing member 10 is clamped and fixed by the upper case 5.

As described above, according to the present invention, when the power cord is held by tightening a nut on the threaded part of the pipe-like holder through which the power cord is inserted, a separately provided fixing member is used. Therefore, when the holder integrally formed with the power cord is clamped and fixed between the lower case and the upper case, the cutout in the lower case can be used to
The fixing member can be inserted into this notched recess, and as a result, only one type of lower case is required, resulting in a significant cost reduction compared to the conventional method of manufacturing two types of lower cases. It is.

[Brief explanation of drawings]

Fig. 1 is a sectional view showing a state in which a holder integrally formed with a power cord is clamped and fixed between a lower case and an upper case, and Fig. 2 is an exploded perspective view showing the holder and the lower case.
