Description

[Detailed description of the invention] The present invention relates to an insulated conductor whose energization state can be recognized.

Generally, insulated conductors such as electric wires and cables have an insulator on the outer periphery to insulate the conductor from others, but do not have a function to indicate whether or not the conductor is energized. Therefore, although it is possible to avoid some danger by separating it from others with the outer insulator, it not only requires another protective member to prevent danger at the conductor connection part, but also prevents electromagnetic effects caused by energization. Since this is impossible, it is necessary to provide a means to prevent close contact, which is both uneconomical and inconvenient.

Therefore, an object of the present invention is to provide an insulated conductor that can recognize whether electricity is flowing through the conductor. Therefore, according to the present invention, an insulated conductor is constituted by a conductor, a current-carrying display provided along the conductor, and a transparent insulating jacket covering the current-carrying display and the conductor. . In this configuration, the energization indicator is an electroluminescent element.

Light-emitting diodes, thermochromic materials, neon display materials, etc. can be effectively used, and various fluororesins can be suitably used as the transparent insulating jacket.

With an insulated conductor having such a configuration, the energization state can be visually checked, which calls attention to the part where the insulated conductor is installed or the installed equipment. This has the effect of providing various new uses.

Next, the present invention will be explained in more detail with reference to the drawings.

FIG. 1 shows an end perspective view of an insulated conductor I according to an embodiment of the present invention. This insulated conductor I uses a twisted conductor 2 as a conductor, and an electroluminescent element 3 is provided along this twisted conductor 2. This electroluminescent element 3 has a twisted conductor 2 on one side of a light emitting member 4.
The transparent electrode 5 is in conductive contact with the other surface, and the transparent electrode 5 is in conductive contact with the other surface.

A transparent insulating jacket 6 made of, for example, fluororesin is provided on the outer periphery of these, and acts as an insulating material for the insulated conductor 1, while also notifying the outside that the embedded electroluminescent element 3 emits light when energized. It's becoming more visible.

When using the insulated conductor 1 according to this embodiment, the transparent electrode 5, which is the other electrode of the electroluminescent element 3, is conductively connected to the ground 7, etc., and a luminescent electric field is applied to the electroluminescent element 3. FIG. 2 is a perspective view of an end portion of an insulated conductor 8 according to another embodiment of the present invention. This insulated conductor 8 has a conductor 9 as a single wire with a round cross section, and has a structure in which a light emitting diode 10 is disposed in conductive contact with the surface of the conductor 9, and the outermost periphery is covered with a transparent insulating jacket 11. It has become.

Here, as best shown in FIG. 3, the light emitting diode 10 has an insulator 13 and a light emitting diode part 14 connected to each other on a flexible electrode plate 12, and a flexible It has a structure in which transparent electrodes 15 are arranged.

Therefore, in this embodiment as well, it is necessary to connect the transparent electrode 15 to the ground 16 etc. and apply a light emitting voltage to each light emitting diode section 14, as in the embodiment shown in FIG.

FIG. 4 shows a perspective end view of an insulated conductor 18 according to yet another embodiment of the invention. In this case, a thermochromic body 20 is provided on the outer periphery of the round conductor 19, and a transparent insulating jacket 21 is provided on the outer periphery.

In this embodiment, the thermochromic body 20 changes color due to Joule heat generated when a current flows through the conductor 19, and this is used to visually check whether the current is flowing. There is no need to worry about grounding one electrode. However, the thermochromic body 20 in this case needs to be set to change color at low temperatures, which may cause malfunctions. In order to eliminate this difficulty, an insulated conductor 23 as shown in FIG. 5 can be used.

In this insulated conductor 23, a conductive thermochromic body 24 is provided on the outer periphery of the round conductor 19, a conductive layer 25 is provided on the outer periphery, and a transparent insulating jacket 26 is further provided on the outermost periphery.
is provided. Here, since the conductive thermochromic body 24 only needs to generate enough heat to cause discoloration, it may have low conductivity and may be semi-conductive, for example, and may be energized by means such as connecting to the ground 27 via the conductive layer 25. Fever is brought on.

FIG. 6 shows a further different embodiment of the invention. The insulated conductor 30 according to this embodiment is provided by wrapping a neon display member 32 around the outer periphery of a round conductor 31 with one electrode in conductive contact with the round conductor 31, and a transparent conductor 32 is provided on the outer periphery of the neon display member 32. It is formed by providing an insulating jacket 33.

Here, the neon display body 32 is formed by, for example, enclosing neon scum between a pair of electrodes, at least one of which is transparent, which are placed opposite each other and are insulated and spaced apart.

According to the insulated conductor 30 according to this embodiment, the conductor 31
Since the neon display body 32 lights up in color when energized, there is no need to worry about grounding the other electrode of the neon display body 32, which is advantageous.

Furthermore, in this embodiment, since the insulated conductor l according to the embodiment shown in FIG. 1 and the insulated conductor 8 according to the embodiment shown in FIG. By arranging the stripes, the color of the colored stripes becomes clear to the viewer due to the light emitted when the conductor is energized, and the effect of making the display clearer can be obtained.

FIG. 7 is a partial perspective view showing a specific example of the neon display body 32.

In the figure, one electrode 35 and the other electrode 36 are made of a transparent electrode body made of synthetic resin, and are placed in a facing arrangement so that both ends thereof are insulated and spaced apart by resin insulators 37ζ. In the space surrounded by these electrodes 35 and 36 and the insulator 37, neon scum is sealed, and an intermittent Q narrowing section 38 is provided to divide the neon gas chamber into a plurality of sections along the longitudinal axis. .

By forming the neon display body 32 in this manner, the light emitting function of the neon display body is not lost even if the insulated conductor is cut to an arbitrary length, which is advantageous.As described above, according to the present invention, By configuring an insulated conductor consisting of a conductor, a current-carrying indicator provided along the conductor, and a transparent insulating jacket covering the current-carrying indicator and the conductor, the insulated conductor is The energization status can be directly observed, which not only alerts people and improves safety, but also has a function to display energization operation, which has the effect of providing various new uses.

Note that the present invention is not limited to the above-mentioned embodiments; for example, the shape of the conductor may be arbitrarily selected, the conductor and the current-carrying display may be arbitrarily combined, or any transparent insulator may be used. Of course, various modifications can be made without using resin within the scope of the idea of this invention.
