BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric wire holder for holding an electric wire such as a lead wire at a certain distance from a chassis or an electric component.

[0002]

2. Description of the Related Art In circuit wiring of a television receiver or the like, high voltage and high frequency current are applied to many electric wires.
In this case, wiring must be performed so that the other electric components and the electric wires do not electromagnetically interfere with each other.

Conventionally, an electric wire holder has been used as a means for holding an electric wire at a certain interval from other electric components. Representative examples of this conventional wire holder include a "lead clamper" disclosed in Japanese Utility Model Publication No. 59-32158, a "synthetic resin stopper" disclosed in Japanese Patent Application Laid-Open No. 63-163010, and the like. 60-617
No. 80, "Holding tool",
"The holding device of the lead wire" disclosed in 193684, "Clamper" disclosed in Japanese Utility Model Application Laid-Open No. Sho 62-14779, and "Cable Holder" disclosed in Japanese Utility Model Application Publication No. 64-3844. And so on.

The common configuration of these wire holders is an inner boss for holding the wire, an outer ring for separating the wire from other components, and connecting the inner boss and the outer ring to each other. It is made up of a plurality of ribs, and is provided with cutout portions in the inner boss portion and the outer ring portion to facilitate introduction of electric wires.

However, in the lead clamper disclosed in Japanese Utility Model Publication No. 59-32158 and the lead wire holding apparatus disclosed in Japanese Utility Model Application Laid-Open No. 58-193684, the inner diameter of the inner boss portion is substantially constant, so that electric wires having different diameters cannot be held. . Japanese Patent Application Laid-Open No. 63-163010 discloses a synthetic resin fastener and a clamper disclosed in Japanese Utility Model Application Laid-Open No. 62-14779, which have a weak holding force and are liable to shift in the axial direction. Since the outer ring portion of the holder of Japanese Utility Model Application Laid-Open No. 60-61780 and the cable holder of Japanese Utility Model Application Laid-Open No. 64-384 are divided in half, locking means for integrally connecting them is required.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide an electric wire holder which can easily attach and detach an electric wire, has a strong electric wire gripping force, and can hold electric wires of different diameters.

[0007]

The electric wire holder of the present invention comprises:
An inner boss portion for holding the electric wire, an outer ring portion for separating the electric wire from other components, and a plurality of ribs for connecting the inner boss portion and the outer ring portion to each other; A wire holder provided with a notch portion on a ring portion to facilitate the introduction of the wire; the inner boss portion includes three axially extending cylindrical portions substantially circumferentially spaced apart from each other; And three flexible thin bow sections integrally molded into the cylindrical sections , each cylindrical section being located substantially in the center of each thin bow section.
And projecting from at least the inner surface of the thin-walled portion
And each thin bow is centered on the inner boss
Curved towards the inside by the three thin bows
A concave triangular-shaped wire holding space is formed, and each of the ribs is integrally connected to an end of each of the thin-walled arc-shaped portions , and the cutout portion has a fan shape in a radial direction of the outer ring. wire holder that characterized in that it is defined by spaced apart pair the ribs and the thin arcuate portion,
This solves the above problem.

[0008]

In the electric wire holder of the present invention, the flexible thin bow portion elastically deforms radially outward according to the diameter of the electric wire. Then, the cylindrical portion substantially makes line contact in the axial direction on the outer periphery of the electric wire. This contact provides conventional three-point support, thus stabilizing the gripping of the wire and increasing the frictional force due to the axial line contact, thereby strengthening the gripping force.

The fan-shaped notch makes it easier to attach and detach the electric wire.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIGS. 1 to 5, an embodiment of a wire holder according to the present invention will be described. As shown in FIGS. 1 and 5, the electric wire holder 1 of the present invention includes an inner boss portion 11 for holding the electric wire 2, an outer ring portion 12 for separating the electric wire 2 from other components (not shown), and an inner boss portion. It comprises a plurality of ribs 13 for connecting the boss 11 and the outer ring 12 to each other.
Notch portions 14 are provided in the inner boss portion 11 and the outer ring portion 12 to facilitate introduction of the electric wire 2.

As shown in FIGS. 1 and 2, the inner boss 11
Are 3 axially distracted, equally spaced circumferentially
It comprises two cylindrical portions 111 and a flexible thin bow portion 112 integrally molded with each cylindrical portion 111.

Each rib 13 is integrally connected to each arcuate portion 112. A cutout portion 14 is defined by a set of ribs 13 and an arcuate portion 112 that are radially fanned apart.

Each arcuate section 112 and cylindrical section 111
Is formed to be thicker in the axial direction than the rib 13 as shown in FIGS. This is to increase the strength of the inner boss portion 11 and the gripping force of the electric wire. Application
The cylindrical part 111 is a medium as shown in FIGS.
The actual cylindrical shape is also included.

Further, as best shown in FIGS.
Adjacent pair of arcuate portions 112 define a variable elongate gap 113 communicating with the notch portion 14 and these gaps 11.
3 unite at the center of the inner boss 11 to form a central opening 114.

The electric wire 2 is, as shown in FIG.
From the central opening 114
Is inserted into. At this time, a part of the cylindrical portion 111 and a part of the bow-shaped portion 112 come into contact with the outer periphery of the electric wire 2 and grip the electric wire 2.

In order to pull out the electric wire 2 from the inner boss 11, the operation reverse to that described above may be performed.

[0017]

According to the present invention, the notch facilitates the attachment and detachment of the electric wire, and the rib, the thin bow-shaped portion and the cylindrical portion are integrally formed, so that the production becomes easy and the electric wire gripping force is reduced. Strengthening, and also allow for the retention of wires of different diameters.
