Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing method for firmly fixing an electric wire which is easily moved or dropped due to pulling or pushing force due to some cause to a device.

[0002]

2. Description of the Related Art Electric wires for supplying and receiving electric power and signals are laid inside or outside equipment such as office automation equipment and home electric appliances, and these electric wires are pulled or pushed in various directions due to various causes. Often receives power. These wires are generally fixed to the main body by a dedicated bush so that they can withstand pulling or pushing forces. However, the fixing method using the dedicated bush is not only high in cost, but also has a problem in that the versatility is small such that the diameter of the bush hole through which the electric wire is inserted is limited. In addition, there is the inconvenience that a special tool may be required to attach and detach the bush including the electric wire.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a method for fixing an electric wire to a device that receives a pulling or pushing force, which is low in cost, does not require a special tool, and can cope with an electric wire having a wide range of thickness. Especially.

[0004]

In order to achieve the above object, the present invention relates to a device for wire-fixing an electric wire which receives a pulling or pushing force inside or outside the main body, with a predetermined space provided at an appropriate place of the main body of the device. Two pairs of binding holes are formed, and the other two binding bodies are attached in a state where the electric wire to which the string-shaped or band-shaped first binding body is tied is attached between the binding holes forming each binding hole pair. The electric wires are bundled after being inserted into each pair of the binding holes, and the first binding body is positioned at an intermediate position between the electric wire binding positions of the two binding bodies.

[0005]

The electric wire and the device body are fixed by tightening the electric wire with the band-shaped binding body inserted through the two binding hole pairs provided in the device body. Further, by tying another binding body to the electric wire portion located between the fixing portions by the two binding bodies, even if the electric wire is displaced due to excessive pulling or pushing force at the two fixing locations, The tied body is caught by the tied body at the fixed location to prevent it from shifting. Furthermore, since it is tightened and fixed by a string-shaped or band-shaped binding body, it is possible to cope with electric wires of various thicknesses.

[0006]

EXAMPLES The present invention will be specifically described below with reference to examples. FIG. 1 is a plan view of a device main body portion for fixing an electric wire, and shows an enlarged surface for fixing an electric wire (for example, an AC cable) connected to the device main body 1. Bundling holes (or fixing holes) 2a, 2a, 2b, and 2b (two pairs of holes arranged in a vertical positional relationship) are provided on the surface of the device body 1 where wires are wired, as shown in the figure. They are provided at various arrangement intervals. The hole diameter varies depending on the diameter of the electric wire, but is, for example, about φ4. The two bundling holes 2a, 2a that are in a vertical position form one pair, and the other bundling holes 2b, 2b form another pair. The interval between the upper and lower binding holes is set to be sufficient for arranging the electric wires 4, and the interval between the binding hole pairs in the left and right positions is appropriately separated.

Next, FIGS. 2A and 2B show a state in which a first binding band (bundling body) 3b is tied in advance to the AC cable 4 to be fixed to the device body 1. This binding band 3b (also other binding bands 3a and 3c described later)
Is a belt or string made of resin, metal or the like, and has a structure capable of being relatively firmly tightened and fixed to the outer peripheral surface of the cable 4. The binding band 3b has, for example, a tightening hole in the thick portion 3b ', and is configured so as to be tightened so that it cannot be pulled out when one end of the belt part is inserted into the tightening hole.

FIG. 3 (a) shows at which position of the device body 1 the AC cable 4 of FIG. 2 is aligned.
FIG. 4 is a perspective view of the state of FIG. 3 (b) seen from the back side. With the cable 4 installed between the upper and lower binding holes, the binding band 3
b is located between the left and right binding hole pairs. From the state shown in FIG. 3 (a), further binding bands 3a are provided on both sides of the binding band 3b.
And 3c, the AC cable 4 is bound to the binding holes 2a and 2b, respectively. That is, as shown in FIG. 3 (b) and FIG. 4, the binding bands 3a, 2b are respectively attached to the pair of binding holes 2a, 2b.
By fixing the cables 4 with the 3c inserted, the fixing of the cables to the device is completed.

As described above, by using the binding band at the two positions of the electric wire like 3a and 3c, the fixing to the main body of the device can be made reliable and the movement of the AC cable can be suppressed as much as possible. In addition, even if there is a case where the AC cable is displaced even if the binding bands 3a and 3c are applied due to an excessive pulling or pushing force, the binding band 3b is located at the intermediate position, so that the binding is performed even if it is displaced. The band 3b can be caught by the binding bands 3a and 3c to prevent the displacement.

[0010]

As described above, according to the present invention, since the electric wire and the main body are fixed to each other by the string-shaped or band-shaped binding body, and another binding body is tied to the electric wire between the fixed portions, it is possible to carry out from any direction. Even if an excessive force is applied, it can be kept fixed to the main body. Furthermore, the string-shaped or band-shaped binding body is not only more cost effective than the dedicated bush, but also applicable to electric wires of various thicknesses.
