Description

Cable with fluorescent display means {CABLE WITH FLUORESCENT MARKING MEANS}

The present invention relates to signal and power cables such as RF and optical, and more specifically, to cables equipped with display means that can improve efficiency by facilitating identification during construction and management.

The installation of cables for signals and power is common not only in each industrial complex or facility, but also within homes, and various cables for signal or power transmission, such as RF cables, feed lines, power lines, optical cables, and ground lines, are used.

To ensure smooth operation at work sites, the sheath of cables used to run electricity is mainly made of black insulator that covers and protects the internal wires.

However, cables made of black insulation are hard to see by workers at work sites, causing various safety accidents.

For example, temporarily connected cables are left unprotected on the floor of a work site, mainly by laying temporary power sources exposed to the outside rather than using wire trays. Additionally, some cables installed in the air impede the movement of workers or cause inconvenience to their work.

In order to solve this problem, attempts are being made to develop safety devices to prevent safety accidents by making the cable coating easily identifiable with the naked eye.

For example, there are cases where an identification tag is configured, and on the cable identification tag, the name of the supply location where the cable is supplied or the user's name are written in letters or symbols. Therefore, the operator can identify the cable through the cable identification tag.

However, since the characters and symbols on such cable identification tags are written with an oil-based marker pen, the characters or symbols may be discolored or discolored by rain or ultraviolet rays, making it difficult for workers to recognize the characters or symbols after a long period of time. When attaching to a cable, there was also a problem of the tape peeling and separating due to rain or ultraviolet rays. In addition, when the purpose of the wire cable changes frequently and it is necessary to frequently change the cable identification tag, the identification tag must be separated from the cable and then a new identification tag must be attached, which makes the replacement work very inconvenient and cumbersome. there was.

Korean Public Utility Model No. 20-2015-000390 discloses a cable equipped with an identification means, and Figure 1 is a perspective view of this.

Looking at this in detail, the cable 100 is configured with an identification means on the surface 150, and the identification means is formed by a solid line 200 formed on the surface 150 of the cable 100. This solid line 200 is formed along the longitudinal direction of the cable 100 on the surface 150 of the cable 100. The surface 150 may be formed in a different color for each cable 100, and the solid line 200 is also formed. It may be formed in at least one of a plurality of colors different from the cable 100.

However, even in this case, there are limitations to identification and classification in the dark of night, and it is difficult to identify signal transmission problems in the cable due to disconnection or twisting.

The present invention was made to solve the above-mentioned problems, and its purpose is to provide a cable equipped with a display means to easily identify the cable and recognize problems in any working environment.

The present invention is a cable including a conductor and a sheath, and includes a groove 1110 formed along the length of the sheath; A fluorescent layer 1101 is inserted and placed in the groove and contains a fluorescent material, and is disposed inside the fluorescent layer to be isolated from external air by the inner wall of the groove and the fluorescent layer, and is oxidized and changes color upon contact with external air due to a disconnection of the coating. A fluorescent display unit 1100 having this changing oxidation layer 1102; A cable including a plurality of disconnected portions 1120 arranged in the groove to prevent the propagation of oxidation and color change by blocking the connection of the oxidation layer in the longitudinal direction of the coating is provided.
The fluorescent display unit allows cables to be distinguished by the color of the fluorescent layer, but when a break in the covering occurs and the oxidation layer comes in contact with the outside air, oxidation propagates in the section between the breaks, allowing a change in color or brightness to be recognized. Improves construction and management efficiency.

Hereinafter, a cable including a fluorescent display means according to the present invention will be described in more detail with reference to the attached drawings.

In the following description, when a part is said to be 'connected' to another part, this includes not only the case where it is directly connected, but also the case where it is connected with another part or device in between. Additionally, when a part is said to 'include' a certain component, this does not mean that other components are excluded, but that it can further include other components, unless specifically stated to the contrary.

The present invention basically provides a cable having a display means made of a fluorescent material on the outer surface of the cable sheath.

The cable applied to the present invention is not limited in type, such as RF cable for mobile communication, KEPCO (electric wire, power line), cable for broadcasting communication, optical communication cable, optical cable, cable for Internet communication, cable for military communication, etc., and the size and material of the sheath or conductor does not limit the concept of the present invention.

Figure 2 is a perspective view of a cable equipped with a fluorescent display means according to the concept of the present invention.

The cable 1000 consists of a sheath 1010 and one or more conductors 1020 disposed inside, and various cable structures of known technology may be applied to this.

In the concept of the present invention, a fluorescent display unit 1100 is configured along the length of the coating 1010 so that it can be viewed from the outside, and fluorescent substances of different colors are coated with different colors depending on the type or thickness of the cable or its purpose. ) It can be formed by printing on the surface or inserting it into the coating 1010.

This fluorescent display unit 1100 can be made by, for example, printing or applying fluorescent ink, and is preferably arranged so as to cover the entire length along the longitudinal direction of the cable 1000.

The color or density that appears on the surface of the fluorescent display unit 1100 is optional and can be determined according to various selection factors such as purpose, function, manufacturer, supplier, and construction company.

In this way, when the selected type of fluorescent display unit 1100 is applied to one cable 1000 and a complex bundle of cables is arranged, they can be easily distinguished by light emission and color, and in particular, identification of twisted wires is excellent.

Meanwhile, according to another embodiment, an additional configuration is presented to facilitate confirmation of disconnection, and this will be examined further.

Figure 3 is a side view of a cable equipped with a fluorescent display means according to a further embodiment of the present invention.

In a further embodiment of the present invention, a groove 1110 is formed along the longitudinal direction in a portion of the coating 1010. The groove 1110 refers to a groove in which the fluorescent display unit 1100 can be placed, and the fluorescent display unit 1100 is inserted into the groove 1110.

This insertion method may be applied in various ways, such as press injection, double injection, or injection printing.

According to an additional concept of the present invention, a fluorescent layer 1101 made of a fluorescent material is applied to the outside of the fluorescent display unit 1100. Additionally, an oxide layer 1102 is disposed inside the fluorescent layer 1101.

The oxidation layer 1102 is isolated from the outside air by the inner wall of the groove 1110 and the fluorescent layer 1101, and may be made of a material that changes color as it oxidizes in contact with air when a coating break occurs.

The oxidation layer may be selected from a material that changes color when in contact with oxygen, for example, methylene blue, new methylene blue, neutral red, indigo carmine, acid red, safranin T, phenosafranine, and capri blue. , Nile blue, diphenylamine, xylene cyanol, nitrodiphenylamine, ferroin, and N-phenylanthranilic acid may be applied.

When color change occurs in this way, oxidation propagates inside the fluorescent layer 1101, causing color change, and the disconnection can be easily recognized by a change in color or brightness.

However, when the entire cable constitutes a single fluorescent display unit 1100 in the longitudinal direction, overall oxidation occurs and disconnection occurs. Therefore, as shown in FIG. 2, disconnections 1120 are formed in some sections of the groove 1110. It is desirable to configure

The oxidation disconnection portions 1120 are arranged at selected intervals (for example, 50 cm) and perform the function of blocking the connection of the oxidation layer 1102 at least.

Therefore, when a cable is cut, oxidation propagates in that section, more precisely, between the cut portion 1120 and the cut portion 1120 in the section, causing a change in color or brightness, making it easily recognizable.

Figure 4 is a diagram showing the use state of a cable equipped with the fluorescent display means of the present invention.

In the illustrated state, four cables are arranged side by side, and the first cable (1000a) is twisted in a direction that is not parallel to the second cable (1000b). Different fluorescent display units 1100 are applied to each cable, and because they emit light in different colors, the recognition of twists is intuitive.

Likewise, in the case of the above additional embodiment, it can be easily confirmed due to the color change of the corresponding cut section.

With the cable equipped with the fluorescent display means of the present invention described above, the installation status and stability of the cable can be easily checked, especially at night, so constructability is improved and it is easy to recognize and deal with problems when they occur. This means improved management convenience and economy.

In addition, because cables can be easily identified by purpose and function, efficiency in storage, construction, and maintenance is improved.

In the above, the present invention has been described in detail based on examples and accompanying drawings. However, the scope of the present invention is not limited by the above embodiments and drawings, and the scope of the present invention will be limited only by the content described in the claims described later.
