The present invention relates to a cable tie, and more particularly, to a cable tie that can determine whether the cable tie is cut by causing the color of the cable tie to change when another person cuts the cable tie once installed.

In general, cable ties are mainly used to bundle and bundle several cables together, and are also used to fix an object to a specific point by connecting to an object to be fixed. 1 shows a perspective view of a conventional cable tie, as shown in the figure, consisting of a band 15 surrounding the cable, a head 11 coupled with the band 15. The head 11 is provided with a fastening ring 13, and when the band 15 is inserted into the fastening groove 12, it is coupled with the fastening groove 12 formed in the band 15 to fix the cable.

Meanwhile, after a communication line such as an optical cable, a telephone line, or a broadcasting cable is laid on the ground or underground, cable ties are used to fix the installed communication line, but cable ties are cut and the communication line is inserted or broadcasted. There are often cases of illegal access to cables. In addition, cable ties are often used to cut cable ties in fixed installations and to change facilities. Conventional cable ties are similar in shape to other cable ties, and there is a problem that it is difficult to recognize the replacement even if the cable ties are cut and replaced. Accordingly, the present applicant intends to propose a cable tie that can recognize illegal facility changes and illegal external cable connections by displaying the cable tie when the cable tie is illegally cut or replaced.

As described above, an object of the present invention is to provide a cable tie that is different from other cable ties due to its color change when cutting the hypothesized cable.

In addition, another object of the present invention is to manage whether or not the cable is damaged by a cable tie that is different in color before and after cutting.

According to the present invention, in the cable tie consisting of a head and a band fixed to the head, in accordance with the present invention, an oxidation-reduction indicator is inserted into the inside of the band, and when cutting a portion of the band, the insertion The redox indicator is reacted with external oxygen to change color and is achieved by cable ties indicating whether the band is cut.

The redox indicator may be indigo carmine or methylene blue.

The band further includes a fastening groove, the guide is formed along the longitudinal direction of the band and disposed on both sides of the fastening groove to protect the fastening groove, the inside of the guide, the length of the guide A guide groove may be formed along the direction in which the redox indicator is to be inserted.

The redox indicator may be applied to an inner circumferential surface of the guide groove.

Preferably, the band further includes a fastening groove along its longitudinal direction.

The above object is according to the present invention, in the cable tie consisting of a head and the band is fixed to the head, the band is provided with a receiving tube for receiving a material having a color, the receiving tube is the band It is embedded and sealed in the interior of the, and when cutting a portion of the band, the material is achieved by a cable tie which is discharged out of the band.

The band may further include a fastening groove along its length direction.

The accommodation tube may be filled with any one of a fluorescent solution, a redox indicator, or a paint.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 shows a perspective view of an example of a cable tie according to the invention.

The illustrated cable tie has a head 52, a band 61, a fastening groove 62, a fastening ring 53, and a pair of guides 63, 64. One surface of the band 61 is provided with a plurality of fastening grooves 62 having a washboard-shaped corrugation structure, and guides 63 and 64 are formed on both sides of the fastening groove 62 to protect the fastening grooves 62. .

The cable ties having the above-described configuration are arranged inside the band 61 so that the color thereof changes when the band 61 portion is cut.

1) redox indicator,

2) phosphor,

3) paints.

One of them may be buried.

The redox indicator described in 1) represents indigo carmine or methylene blue. Indigo carmine is yellow when it is blocked with oxygen, but becomes red when it is in contact with oxygen, and turns green when it is in contact with a large amount of oxygen. Thus, indigo carmine is used as a reagent to test redox reactions in chemical plants or laboratories. In the present invention, the indigo carmine solution (or diluted aqueous solution) may be inserted into the band 61, or indigo carmine may be applied, and it may be determined whether the cable 61 is cut in the band 61 portion of the cable tie.

On the other hand, indigo carmine has a characteristic that the color changes depending on the amount of reaction with oxygen, so that the color of the band of the end band of the cable tie and the color of the band of the head 52 side is different from each other. If the cut is made at point C of the band shown in FIG. 2, the color of the region A, which is supplied with the most external oxygen, is green, and the region B is red. In addition, the areas A and B are unified in the same green and red colors, and each area itself has a light or dark color as the amount of oxygen supplied is large and small, so that the overall color of the cut band 61 has various spectra. To have. Therefore, it is difficult to equalize the color of the cable tie once installed, and the conventional cable ties produced mainly in white or black are notable because they do not implement the color spectrum formed by indigo carmine.

Methylene blue is colorless when blocked with oxygen, but becomes blue when it encounters oxygen. When the methylene blue is inserted into the band 61, the color of the cable tie has the same color as that of a conventional cable tie and is not externally distinguished. When cutting the band 61 portion for the construction of a cable or facility, methylene blue reacts with external oxygen to turn blue. Therefore, the cable tie in which methylene blue is inserted has a different color from the existing cable tie, and when a broadcasting cable is connected or illegally hypothesized its cable, the cable tie of the illegal hypothesis is different. Through this, when the cable tied with cable tie is illegally cut and replaced with a normal cable tie, it is different from the surrounding cable tie (cable tie whose color is changed by methylene blue), so it is easy to recognize illegal hypothesis and connection. Can be.

The phosphor can be applied when the cable tie is used in the dark. Phosphors emit light for a period of time after they receive light, so they can be distinguished from conventional cable ties when used in ceilings, underground boilers, and building switchboards. If the building cable is bundled using a cable tie in which phosphor is inserted in the building switchboard, the operator can directly distinguish the cable tie according to the present invention from the cable tie according to the present invention by simply looking at the flash. .

When the paint is inserted into the band 61, when the band 61 is cut, a colored liquid (color) flows out. When the paint is inserted into the band 61, the band 61 of the cable tie is preferably used after the cable is bundled and not cut. When the end of the band 61 is not cut, the color of the cable tie has a color of paint. When cutting the cable tie, the paint inserted into the band 61 is discharged to the outside to surround the cable tie. The paint spreads to determine whether the cable tie is cut.

3 to 5 show various examples in which the redox indicator, the phosphor, or the paint is inserted into the band 61.

First, FIG. 3 shows an example in which guide grooves 63a and 64a are formed in a guide formed in the band 61.

The guide grooves 63a and 64 are formed along the guides 63 and 64 provided in the band 61, and the guides 63 and 64a (hereinafter referred to as guide grooves will be described based on reference numeral 64a) have a cylindrical shape. Take the form of a pipe. Both ends of the guide groove 64a are sealed, and the redox indicator, phosphor or paint remains inserted into the guide groove 64a. Accordingly, the guides 63 and 64 have the color of the material inserted into the guide groove 64a, and thus have the appearance of a two-color stripe.

Next, FIG. 4 shows an example of forming a space in the band 61 and using the same.

As shown in the figure, a space 65 having a rectangular band shape is provided inside the band 61, and the material described in 1) to 3) is filled in the space 65. In the illustrated embodiment, a sufficient space is provided inside the band 61, and an oxidation-reduction indicator, a phosphor, or a paint may be inserted therein, and the color of the material filling the inner color of the band 61 itself may be changed. You can make it stand out.

Finally, FIG. 5 shows a variant embodiment for FIG. 4.

5 is similar to that described with reference to FIG. 4 to form a space inside the band 61, but the space 66 formed inside the band 61 is more similar to the fastening groove 62. FIG. It is characterized by increasing the mechanical stability of the fastening groove 62 by being spaced apart. Since other things are the same as those described above with reference to FIG. 4, redundant descriptions thereof will be omitted.

Meanwhile, in the structure described with reference to FIGS. 3 to 5, the substances (oxidation-reduction indicators, phosphors) described in 1) to 2) are filled in the liquid state, or the guide grooves 63 and 64 (or inside the band It may be applied to the space (65, 66). After applying the oxidation-reduction indicator or phosphor to the guide grooves 63 and 64 (or the spaces 65 and 66 formed inside the band), the liquid is not discharged to the outside even if the band 61 is cut when sealed. There is an advantage, and only the color of the cable ties can be changed, for this purpose, the redox indicator is preferably inserted in the band 61 in a vacuum state, the phosphor does not require this condition.

6 shows a form in which the head 52 and the band 61 of the cable tie are coupled, and FIG. 7 shows a form in which the end of the band 61 shown in FIG. 6 is cut.

6 shows a cable tie according to the present invention, and a form in which a conventional cable tie is fastened. Usually, after a cable tie is bundled or a facility is fixed, the area E of the band 61 is cut with a nipper or a knife. However, when paint is filled in the band 61, the E region is not cut. When the paint is filled in the band 61, as shown in Fig. 7, when the E region is cut, the paint filled inside flows out and spreads the paint around the cable tie.

When the band 61 is filled with an oxidation-reduction indicator or phosphor and the cable is not tied, the E region is not cut.

4) When indigo carmine is filled as a redox indicator in the guide groove (or the space 65 formed inside the band), the band 61 of the cable tie is yellow and the band 61 Is illegally cut, it turns red or green.

5) When methylene blue is filled as a redox indicator in the guide groove (or the space 65 formed inside the band), the band 61 of the cable tie becomes the color (usually white) of the band 61 itself. ) And turns blue when the band 61 is cut illegally.

6) When the phosphor is applied to the guide groove (or the space 65 formed inside the band), the color of the band 61 maintains the material color of the band 61 itself in a bright place, but when irradiated with light in a dark place, Light up for time.

That is, the cable tie according to the present invention can be used after cutting the band 61, or without cutting, after tying the cable, and the color before and after the band 61 is cut changes the cable tie easily. You can judge.

Herein, the cable ties having the fastening grooves are described as an example, but it is obvious that the cable ties not provided with the grooves may be included as described above.

As described above, the present invention provides a method of filling a cable tie with redox indicators, phosphors, or paints, and by using the same to change the color before and after the cable tie is cut to determine whether the cable tie is dirty or illegally cut. It can be determined.
