And a connecting portion 4A connecting the bases 1 and 2 to each other. When using the wire cable fixture in the normal upright position,
A support portion 4 is formed from the connecting portion 4A and the base 2, and the support 1 supports the base 1 at a height away from a fixing surface (not shown). When the wire / cable fixing device is used in an inverted state, a support portion 4 is formed from the connecting portion 4A and the base 1, and the base 2 is supported by the support portion 4 at a height away from the fixing surface. .

As shown in FIGS. 1 and 2, when the electric wire / cable fixing device is used in the upright state, a pair of locking holes 11A, 11
B are formed, and the binding band 1 is formed by the bridge-shaped hooking portions 12A, 12B forming the hooking holes 11A, 11B.
0 is latched. A recess 13 for mounting an electric wire (member) is formed in a direction orthogonal to the hook holes 11A and 11B on a horizontal plane, and is fastened by the binding band 10 penetrating the hook portions 12A and 12B. Wire is recessed 1
3 and is fixed to the wire / cable fixture.

As shown in FIGS. 3 and 4, a pair of engaging holes 21A and 21B are formed in the upper portion of the base 2 at positions opposed to each other in the horizontal direction in the inverted use state.
A bridge-shaped hook portion 2 forming the hook holes 21A and 21B.
The binding band 10 is hung by the 2A and 22B. In the direction orthogonal to the hook holes 21A and 21B on a horizontal plane,
A concave portion 23 for mounting the electric wire (member) is formed, and the electric wire fastened by the binding band 10 penetrating the hooking portions 22A and 22B is pressed by the concave portion 23 and fixed to the electric wire cable fixture. .

In the electric wire / cable fixing device, the base 1, the support portion 4 and the base 2 are located at substantially the center positions in plan view.
A mounting hole 3 for screwing the wire / cable fixture to the fixing surface is formed. In the upright use state, the mounting holes 3 are provided from the position below the line connecting the locking holes 11A and 11B with the locking holes 12A and 12
It is formed to penetrate to a position above the line connecting B. Tapers 31, 32 are provided in the middle of the mounting hole 3 so that the inner diameter of the mounting hole 3 is smaller than the opening into which the screw is inserted.

The taper 31 is formed at a height lower than the height of the screw head from the opening end of the mounting hole 3 on the base 1 side so that the upper end of the screw does not come into contact with the binding band 10 at the time of screwing. Have been. Similarly, the taper 32 is provided at a position lower than the opening end of the mounting hole 3 on the base 2 side by the height of the screw head in the inverted use state. FIG. 5 is a perspective view showing an example of a use state (when the erect cable is used). In this case, two electric wire cable fixing devices 1A and 1B are fixed to the fixing surface 9, and the upper bases of these electric cable fixing devices 1A and 1B. An electric wire 8 is mounted on the table using a binding band 10. Thereby, a sufficient gap 81 can be formed between the electric wire 8 and the fixing surface 9.

As described above, the support portion 4 is provided, and the binding band 10 is made to penetrate through the retaining hole provided on the upper portion, so that the base 1 for retaining the binding band 10 is raised from the fixing surface. As shown in the prior art, the height of the base itself is low and the distance between the locking hole for passing the binding band 10 and the fixing surface is shorter than that of the electric wire and the fixing surface. Since a sufficient gap can be formed between them, dust is less likely to adhere, and operations such as cleaning and washing can be easily performed. Also, taking into account the amount by which the electric wire (member) naturally bends due to work, changes over time, etc., the base 1 is positioned at such a height that a sufficient gap can be obtained between the bent electric wire and the fixed surface.
Is supported by the support portion 4, the effect can be surely obtained.

As the support portion 4, a second base for hanging the binding band 10 when the electric wire / cable fixing device is used in an inverted state, and a connecting portion 4A for connecting the bottom of the base 1 and the bottom of the base 2 to each other. , A plurality of types of bases can be provided in one wire / cable fixture. Therefore, by providing the bases 1 and 2 having different shapes, the functions of two types of bases can be obtained with one electric wire / cable fixture.

A concave portion 13 is provided at the upper end of the base 1 so that the wires (members) are placed in a direction perpendicular to the hook holes 11A and 11B in the upright use state. Can be hooked more reliably. Furthermore, since the recessed portion 13 is formed at the upper end of the base 1 so as to be in contact with the fixed surface in the inverted use state, the electric wire can be more securely hooked in the upright use state, and in the inverted use state. There are two effects that the wire / cable fixture can be stably fixed to the fixing surface. Note that the same effect can be obtained for the base 2 as well.

When the electric cable fixing device is attached to the fixing surface, the electric cable fixing device may be screwed to the fixing surface using the mounting hole 3, but as shown in FIG. May be attached to the fixed surface. Here, as shown in FIGS. 1 and 2, the arm-shaped (column-shaped) fixing member 9A and the wire / cable fixing tool 1A, 1B with the binding band 10A, and the electric wire / cable fixture 1
A and 1B are fixed to the fixing surface 9 of the fixing member 9A. Thereby, the electric wire can be easily fixed to a place where it is difficult to screw.

In the above, the case where a pair of locking holes 11A and 11B (12A and 12B) are provided on the upper portion of the base 1 (base 2) has been described. However, as shown in FIG. A retaining hole may be provided. Here, a base 5 is supported by a columnar support portion 4, and a pair of locking holes 51 </ b> A and 51 </ b> B are formed in the upper part of the base 5 so as to face in the horizontal direction. A pair of locking holes 51 so as to face
C, 51D are formed. These pairs are arranged in directions orthogonal to each other on a horizontal plane. Hook hole 51
A to 52D, which form cross-linking hooks 52A to 51D, respectively.
52D is formed at a height slightly lower than the upper end corner of the base 5, and forms concave portions 53A to 53D for mounting electric wires, respectively.

As described above, the base is provided with a plurality of pairs of locking holes, and the pair of locking holes are arranged orthogonal to each other. , Two types of base functions can be obtained with one base. For example, when two pairs of hook holes having different inner diameters are provided, the optimum hook holes can be used for binding bands having different widths, and the binding bands can be stably fixed. Further, by forming the concave portions having different widths for each pair, it is possible to use optimal concave portions for electric wires having different thicknesses, and to stably mount the electric wires.

Further, as shown in FIG. 7 and FIGS. 3 and 4 described above, the area of the bottom surface of the support portion 4 in contact with the fixing surface may be smaller than the area of the base in plan view.
Thus, the area occupied on the fixing surface required for fixing the wire / cable fixing device can be reduced, and dust adhering to the lower end of the wire / cable fixing device can be reduced. Further, the influence of the positional relationship during mounting and the mounting area on other components mounted on the fixed surface can be reduced. In the above, the case of fixing a cable band that binds electric wires used in an electric device will be described as an example.However, the present invention is not limited to this, and the present invention is applicable to any case of a binding band that binds members. It can be applied, and a similar effect can be obtained.

[0021]

As described above, according to the present invention, the base for hooking the binding band is separated from the fixing surface by the support portion by passing the binding band through the hook hole provided in the upper portion. As it is supported at the height position, compared to the conventional one where the height of the base itself is low and the distance between the locking hole for passing the binding band and the fixing surface is short, it is fixed to the electric wire cable. Since a sufficient gap can be formed between the surfaces, dust is less likely to adhere, and operations such as cleaning and cleaning can be easily performed.
