Description

Technical field

The utility model relates mainly to the electrical industry and can be used for terminal termination of cable and wire products.

State of the art

Cable marking is a fairly significant process, as it simplifies cable routing. In addition, the use of labeled product samples greatly simplifies subsequent maintenance and control of cable networks, as well as reduces the time spent on sorting and identification and reduces the likelihood of accidental errors.

Various equipment is used for marking the cable, which mainly differs in the method of marking (labeling) the wire. In particular, the marking disclosed in the application for invention CN 105138944, published on 12/09/2015, in which the power cable or optical cable is provided with electronic tags (2.4-GHz active RD-QQ2013 chips and TD-JY005 RF chip, is known in the prior art). 900 MHz), housed in a plastic label housing mounted on a cable.

The disadvantage of this technical solution is the low reliability of the device as a whole, due to the insufficiently strong fastening of the plastic case for labels.

The closest set of essential features to the claimed utility model is the technical solution disclosed in the international application WO 2014/184385, published on 11/20/2014, which consists in the fact that indicators having a constant and customizable marking function are enclosed in a shell made of glass or ceramic material, and are located in the cable sheath with a certain interval along its length.

The disadvantage of this technical solution is the complexity and, accordingly, the high cost of products labeled in this way, as well as low reliability due to the use of glass or ceramic shells.

Utility Model Disclosure

The technical result, to which the claimed utility model is directed, is to simplify the design of label mounting while increasing the reliability of marking.

The specified technical result is achieved due to the fact that the terminator of the cable and wire products includes a housing and a tag placed inside it, made in the form of a passive, non-contact microchip with cryptographic protection. In this case, the body is made of heat-shrinkable material.

The mark can be placed on the end or on the side surface of the housing.

The presence of a housing made of heat-shrinkable material will allow it to be securely fixed at the end of cable and wire products, and the placement of a label inside the housing will protect it from mechanical and chemical damage during transportation and operation.

An embodiment of the utility model. The terminal of the cable and wire products is a housing (1) and a mark (2) placed inside it. For the purpose of covert marking of cable and wire products, a microchip with a high degree of cryptographic protection is used as a tag, in particular a passive (without power), non-contact microchip, for example, a microchip with a working distance of 50 to 500 mm, having cryptographic protection with a key, size 192 bit. Depending on the production need, another microchip having cryptographic protection with a key of a different size can be used.

Various types of microchips can be used:

in the radio frequency range UHF (860-960 MHz), LF (125-134 KHz) and HF (13.56 MHz);

by type of memory: RO (only reading information recorded during chip manufacturing), WORM (reading and once rewritable information), RW (repeatedly rewriting information);

by complexity (size) of the cryptographic encryption key 56, 64, 80, 112, 128, 168, 192, 256 bits and higher;

according to the range of reading / writing information: from 10 mm to 10000 mm (1 cm - 10 m). The location of the label inside the housing allows you to:

- eliminate the effect on the chip of magnetic interference from a high mass of metal in the cable;

- increase the resistance of the chip to mechanical loads during transportation (vibration, mechanical shock);

- minimize the impact on the chip of high temperatures (up to + 250 ° C) during heat shrinkage and low (up to -50 ° C) during transportation and storage of the cable in open areas;

- protect the ends of cable and wire products during transportation and storage from moisture, dirt, oxidation, including the use of a terminal with a built-in nipple that allows you to save certain types of cable under pressure or in a nitrogen atmosphere.

The terminal case is made of a special heat-shrinkable material, which is compressed when heated, reducing the diameter of the terminal case and hermetically closes the free end of the cable-conductor products. To increase the tightness of the fit and additional fixation of the terminal at the end of the cable, the inner surface of the terminal is additionally coated with hot-melt adhesive.

Each tag is authorized and personalized in the database of cable products. Each microchip has several unique numbers that are recorded in the database. The presence of cryptographic protection on the microchip and its registration with several unique numbers in the database makes the possibility of breaking it in, forgery or cloning from an economic point of view.

In the database, using specialized software that provides user identification and protection of the entered data, a record is created for each commodity unit (drum, bay, construction length) produced or imported into the Russian Federation of cable and wire products. After creating a record of a product, records of two tags that were previously entered into the database are attached to it. These two marks are placed at the two ends of the cable or wire of the corresponding commodity unit.

The mark (2) is placed inside the housing (1) of the cable terminator using hot melt adhesive (3). The mark can be placed on any inner surface of the cable terminal housing (at the end, on the side surface). The cable terminator is put on at the free end of the cable-conductor products (4). Further, under the influence of high temperature, with the help of an industrial hair dryer or blowtorch, heat shrinkage of the terminal case is performed. When heated, the special material of the terminal box body is compressed and tightly fits the end of the cable or wire. The adherence density is further enhanced by the hot-melt adhesive applied inside the terminal case.

During heat shrinkage, the mark is tightly fixed between the inner wall of the terminal housing and the outer surface of the cable or wire. The label is protected against accidental loss, moisture or dirt.

The label is located inside an opaque terminator and is not accessible for visual or mechanical contact. In this case, the label is available for reading and writing using a contactless reader operating at a given frequency and equipped with specialized software. Using the specified software, the reader accesses the database using the label as an access key and an identifier for a record in the database about a specific commodity unit.

When a cable or wire unit is delivered to a new owner (distributor, retail outlet, end consumer) using a contactless reader operating at a given frequency and equipped with specialized software for any of the two tags placed on the unit, you can get information about this products in accordance with the granted access rights: in off-line mode you can read the minimum information that is written on the label, for example: label number, manufacturer, country and production, manufacturer's TIN, production date, product brand, number of products, item number (drum, bay, pallet), and on-line in accordance with access rights, you can get detailed information from the database: item weight, information on scientific and technical documentation, certification information, type of marking, date of testing, controller of the technical control department, date of retesting, actual values of test results (acceptance test report for up to 20 different parameters), d transport packaging, information about the materials used, copies of supporting documents, etc.

When using a cable or wire - connecting it to an electric or information network, using a contactless reader operating at a given frequency and equipped with specialized software for any of the two tags, you can perform the procedure of "disposal" of a given commodity unit from circulation. The right to carry out the “retirement from circulation” procedure is granted to identified users in accordance with established access rights. After the retirement procedure, the database additionally displays data on the place, date of application of the products, responsible persons in the application, the number of products used, etc. etc. This information will be available to users of the information system in accordance with the granted access rights for special links and access keys generated by the system for 25 years.

When mounting a cable or wire, the tags along with the terminators are cut off and must be disposed of or reused.
