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 groove 12, it is coupled with the fastening groove 14 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 provide a cable tie that is different in color before and after cutting. In addition, another object of the present invention is to provide an RFID tag to the cable tie, thereby providing a cable tie that can continuously manage the cable management situation, such as installation time, maintenance situation, operator of the cable tie.

According to the present invention, in the cable tie consisting of a head and a band connected to the head, according to the present invention, an RFID tag is disposed on one side of the head and the band, and a sealed space is formed inside the band. And a redox indicator is inserted into the enclosed space, the color of which is changed when the redox indicator is in contact with the outside air, thereby achieving a cable tie indicating whether the cable tie is cut.

Preferably, it is formed on one side of the band, and further comprises a cradle for receiving the RFID tag.

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

2A-2C show a perspective view of a cable tie according to the invention.

The cable ties shown in FIGS. 2A-2C include a head 52, a band 61, a fastening groove 62, a fastening ring 53, a pair of guides 63 and 64, a cradle 65, and an RFID. It has a tag. 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 for protecting the fastening grooves 62 are formed at both sides of the fastening groove 62. .

The cradle 65 is formed integrally with the band 61. Since the band 61 is bent in a circular or oval shape when wrapping the cable, it is not suitable to place the RFID tag 70 on the band 61 itself. Therefore, it is preferable to attach the RFID tag 70 to the cradle 65 formed on one side of the band 61 or to insert the RFID tag 70 into the cradle 65. When the RFID tag 70 is attached to the cradle 65, the RFID tag 70 preferably has a tape in which an adhesive material is applied to a surface attached to the cradle 65, and a separate battery is required. It is preferable that it is a passive type RFID tag.

First, FIG. 2A shows a perspective view according to one example of a cable tie.

In the cable tie shown, the face of the cradle 65 is disposed perpendicular to the face of the band 61. When the surface of the holder 65 is disposed perpendicular to the surface of the band 61, the fastening groove 62 is bound to the band 61 so that the holder 65 is bent in a circular shape. So that it does not bend with

Next, the cable tie shown in FIG. 2B shows an example in which the surface direction of the band 61 and the surface direction of the holder 65 are arranged in parallel. In this case, in order not to bend the cradle 65 according to the deformation of the band 61, only the center portion of the cradle 65 should be joined to the surface direction of the band 65. This will refer to FIG. 10.

Finally, the cable ties shown in FIG. 2C show that the band 61 and the head 52 form a neighboring area in a “+” shape. The RFID tag 70 is disposed in the cradle 65 having a “+” shape, and is disposed in an area not intersected with the band 61. Through this, even when the band 61 is fastened to the fastening groove 53 to form a cable tie in a circular shape, no external force is applied to the cradle 65, and the RFID tag 70 is attached or inserted into the cradle 65. ) Is not damaged.

An RFID tag may be attached to the cradle 65 of the cable tie having the shape of FIGS. 2A to 2C or may be inserted into the cradle 65. The form in which the RFID tag 75 is attached to the cradle 65 will be described with reference to FIG. 3.

3 shows an example in which the adhesive RFID tag is mounted on the holder 65.

As shown, the RFID tag 75 is composed of an RFID chip 71a and a pair of antennas 72a and 74a. The RFID chip 71a and a pair of antennas 72a and 74a are attached to the tape base 73a. The RFID chip 71a is disposed in an area where the band 61 and the cradle 65 intersect, and the antennas 72a and 74a are respectively disposed in an area protruding from the band 61. The illustrated antennas 72a and 74a have a bow tie type suitable for the UHF frequency band and have a symmetrical structure around the RFID chip 71a. An adhesive material is applied to the surface of the base 73a on the side facing the holder 65, and the base 73a may be attached to the holder 65 using the adhesive material. Accordingly, the operator can attach the RFID tag 75 to the holder 65 after the cable is arranged using the cable tie, and there is a risk of damaging the RFID tag 70 during the cabling operation using the cable tie. none. The pair of antennas 72a and 74a have a triangular structure (bow-tie structure) to facilitate data transmission and reception in a high frequency band (eg, an ultra-high frequency (UHF) band).

4 shows an example of an RFID tag formed inside the cradle 65.

The illustrated RFID tag 76 is embedded in the cradle 65 and has a spiral antenna 72b around the RFID chip 71b. This type of antenna 72b may have a longer antenna than the bowtie type and is suitable when the transmission frequency of the external transponder is relatively low. Preferably, the antenna 72b is bent and disposed along the edge of the cradle 65. The length of the antenna 72b is determined according to the response frequency of the RFID chip 71b embedded in the cable tie. In general, the higher the response frequency of the RFID chip 71b, the shorter the length of the antenna (e.g., reference numeral 72b), and vice versa.

5 shows an example in which an RFID tag is embedded in a cradle.

The illustrated RFID tag 77 embeds an RFID chip 71c in an area where the band 61 and the cradle 65 intersect, and has a bowtie-type antenna 72c having a symmetrical structure around the RFID chip 71c. 72d).

In this embodiment, since the RFID tag 77 is embedded in the holder 65, after arranging the cables using cable ties, the RFID tag 77 is less likely to be damaged.

Meanwhile, the RFID tags 75, 76, and 77 described with reference to FIGS. 3 to 5 disclose a form attached to the holder 65 and a form embedded in the holder 65, and mainly include a bow tie suitable for the UHF band ( The bow-tie antenna is mainly illustrated. However, the cable tie according to the present invention may be implemented in various forms when the transmission frequency of the external transponder performing data communication with the RFID chips 71a, 71b, and 71c exceeds or falls short of the UHF band. . For example, the antennas 72a, 74a, 72b, 72c, and 72d may have a dipole shape, a shape shown in FIG. 4, and a three-dimensional shape using mems. In the present specification, only one or two antennas are referred to for convenience of understanding and description, and the shape of the antenna does not obscure the subject matter of the present invention.

The cable ties described with reference to FIGS. 2 to 5 are used for the construction of communication lines and switchboards, and the operator uses a separate tag reader (not shown) to manage cable ties such as installation time, maintenance situation, and operator. Information about the situation can be recorded. If a worker installs a communication line such as a telephone line or an internet line, the worker can use the tag reader to record the date and time on which the communication line was laid and the worker information. The information recorded in the tag (for example, reference numeral 75) can be read to obtain worker information and temporary date and time information. This information is particularly useful for the construction of wiring and communication lines that require security.

In addition, the cable tie can minimize illegal facility changes or illegal theft of communication lines caused by others.

For example, when a person receives a broadcast by unauthorized access to the broadcast cable, the cable tie (cable tie according to the present invention) that binds the broadcast cable should be cut and the broadcast cable should be connected with a new cable tie (existing cable tie). do. In this case, the illegally installed cable ties are not read by the tag reader, and the form of the cable ties is also differentiated from the cable ties according to the present invention.

On the other hand, when the cable tie according to the present invention is illegally cut, in order to make it easier to determine, it is possible to fill the inside of the cable tie redox indicators, phosphors, and paints. The redox indicator makes it easy to determine whether the cable tie is illegally cut by causing the color to change in response to external oxygen when a portion of the band 61 is cut.

Here, inside the band 61,

1) redox indicator,

2) phosphor,

3) one of the paints 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 the point C of the band shown in Fig. 2, the color of the A region (see Figs. 2A to 2C) where the external oxygen is supplied the most is green, and the B region (see Figs. 2A to 2C) It becomes red. In addition, the areas A and B are not unified in the same green and red color, but each area itself has a light or dark color due to the high and low amount of oxygen supply, so that the entire color of the cut band 61 has various spectra. Will 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 to the cable or illegally laid its own cable, it is differentiated from a cable tie of an illegal worker. 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.

6 and 7 illustrate an example in which the redox indicator, the phosphor, and the paint are inserted into the band 61.

First, FIG. 6 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 64a (hereinafter, the guide grooves will be described based on the reference numeral 64a) are formed along the guides 63 and 64 provided in the band 61 and have a cylindrical shape inside the guides 63 and 64. Take the form of a pipe. Both ends of the guide groove 64a are sealed, and the redox indicator, the phosphor, and the paint remain inserted into the guide groove 64a. Therefore, the guides 63 and 64 have the color of the material inserted into the guide groove 64a, and thus have the same appearance as the two-colored ribbons.

Next, FIG. 7 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 shape is provided in the band 61, and the material described in 1) to 3) is filled in the space 65. The illustrated embodiment ensures sufficient space inside the band 61, inserts redox indicators, phosphors, or paints therein, to give the color of the material that fills the inner color of the band 61 itself. can do.

Meanwhile, in the structure described with reference to FIGS. 6 and 7, the substances (oxidation-reduction indicators, phosphors) described in 1) to 2) are filled in the liquid state or the guide grooves 63a and 64a (or inside the band). It can be formed and applied to the space 65. After applying the redox indicator or phosphor to the guide grooves 63 and 64 (or the space 65 formed inside the band, the band 61 is cut when sealed. Even if the liquid substance is not discharged to the outside, only the color of the cable tie can be changed, and for this purpose, the redox indicator is preferably inserted into the band 61 in a vacuum state. Do not need.

8 shows a form in which the head 52 of the cable tie and the band 61 are coupled, and FIG. 9 shows a form in which the end of the band 61 shown in FIG. 8 is cut.

8 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. 8, when the E region is cut, the paint filled inside flows outward 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 into the guide groove (or the space 65 formed inside the band) as an redox indicator, 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 is colored (usually white) of the band 61 itself. When the band 61 is cut illegally, it turns blue.

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 hours.

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. In addition, the RFID tag formed on the cable tie may be blocked at the same time as the illegal cutting of the cable tie may be recorded, and various information about the temporary status of the cable tie, the timing, and the operator may be recorded and managed.

As described above, the present invention fills cable ties with redox indicators, phosphors, or paints, and uses the same to determine whether the cable ties are illegally cut by varying the color before and after the cable ties are cut. You can judge. In addition, the present invention can be equipped with an RFID tag inside or on the surface of the cable tie, it is possible to systematically manage the work using the same. In this case, an operator and a work date and time may be recorded or read in the RFID tag. In addition, the present invention can easily determine the person in charge, when a problem occurs in the construction through the information obtained on the operator and the temporary date and time obtained through the cable tie.
