Description

Technical Field

[0001] The present application relates to the technical field of cables and electronic tags, and in particular to an electronic tag and a communication cable. Background Art

[0002] In the ODN field, a large number of outdoor optical cables and jumpers need to be labeled for distinguishing management. Although traditional hanging labels or printed marks can solve the problem of distinguishing optical cables, when the optical cables are laid and dragged, the installed hanging labels are easy to fall off, and the dragging friction can easily cause the printed marks to be blurred, affecting the distinction between cables or optical cables.

[0003] Therefore, using optical cables with embedded smart passive electronic tags can solve the above-mentioned installation problems. However, for jumpers with connectors added at both ends, it is impossible to ensure that there are electronic tags at both ends due to the different lengths of the jumpers. In addition, it is impossible to embed electronic tags in the already laid optical cables without embedded smart electronic tags. Utility Model Content

[0004] The embodiments of the present application provide an electronic tag and a communication cable to solve the problem in the related art that when an embedded intelligent passive electronic tag is used, a jumper with connectors is added at both ends. Due to the different lengths of the jumpers, it is impossible to ensure that both ends of the jumper have electronic tags; and it is difficult to add intelligent electronic tags to the laid optical cables without embedded intelligent electronic tags at a later stage.

[0009] Since an elastic pre-tightening member is provided in the internal channel of the fastening sleeve, and is clamped and sleeved on the optical cable by the elastic pre-tightening member; a transparent protective sleeve is sleeved on the fastening sleeve; the electronic tag body is located between the transparent protective sleeve and the fastening sleeve, and is pressed and held on the outside of the fastening sleeve by the transparent protective sleeve; by setting the elastic pre-tightening member as above, the fastening sleeve can be stably connected to the outside of the optical cable, and relative sliding will not occur during laying and dragging; when movement is required, the large elastic force can be overcome to move, so that any number of fastening sleeves can be sleeved on the optical cable to meet the need for electronic tags at both ends; optical cables without embedded intelligent passive electronic tags can be temporarily added or removed later, thereby facilitating the needs of convenient removal of electronic tags and the need for stability and non-falling off during use.

[0010] This structural form is an external electronic tag, and the electronic tag can be removed and added as needed, which is more convenient than embedded intelligent passive electronic tags. It finally solves the problem that when using embedded intelligent passive electronic tags in the related technology, connector jumpers are added to both ends. Due to the different lengths of the jumpers, it cannot be guaranteed that there are electronic tags at both ends of the jumpers; and it is difficult to add intelligent electronic tags to the laid optical cables without embedded intelligent electronic tags at a later stage.

[0011] In some embodiments, the transparent protective cover is made of a transparent heat shrinkable material.

[0012] In some embodiments, the length of the transparent protective sleeve in the axial direction of the optical cable is greater than the length of the fastening sleeve in the axial direction of the optical cable;

[0014] In some embodiments, the elastic preload member includes a plurality of elastic ribs distributed circumferentially along the inner wall of the fastening sleeve;

[0018] The inner channel of the fastening sleeve is a cylindrical channel, the outer contour of the cross section of the fastening sleeve is a polygon, each corner of the polygon is an arc angle, and the curvature radius of the arc angle is greater than the design value.

[0019] In some embodiments, the polygon is a triangle or a quadrilateral.

[0020] In some embodiments, the electronic tag body includes a flexible substrate, on which a rectangularly distributed antenna is disposed, and on which a chip connected to the antenna is disposed;

[0021] A barcode area and a serial number area are arranged on the flexible substrate and inside the rectangle.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] Existing optical cables use embedded intelligent passive electronic tags to achieve intelligence, but ODN wiring requires the actual line length to cut the optical cable, and there is no guarantee that both ends of the optical cable have embedded electronic tags; in addition, there are still a large number of traditional optical cables (optical cables without embedded intelligent electronic tags) in the existing network.

[0037] The RFID tag is attached to the corresponding optical cable, and the attached tag is easy to fall off. In addition, if the tag is not encapsulated, it cannot meet the harsh outdoor environment.

[0038] After the tag is packaged, it is fixed to the optical cable near the connector in a similar way to a cable tie. The wiring equipment is connected to multiple optical cables. After bundling, the position of the RFID tag is uncertain, which makes it difficult to read. In addition, when the optical cable is dragged, the installed tag is easily dropped.

[0039] Existing cable electronic tags have no indicator lights to guide operation, no barcodes, and are difficult to trace after the tags are damaged.

[0040] Flexible labels with indicator lights, such as PET protective film labels, consume energy to light up the indicator lights, so the antenna and label sizes are large. The chip and indicator lights of the label are attached to the antenna with conductive adhesive. The label is bent and stressed, which can easily cause the chip, indicator light and antenna to peel off, resulting in label failure.

[0041] In view of the above problems, an electronic tag and a communication cable are proposed.

[0042] First, see Figure 2 and Figure 3 , an electronic tag, comprising:

[0043] A fastening sleeve 1, in which an elastic pre-tightening member 3 is provided in an inner passage thereof, is used to clamp and sleeve the optical cable 2 through the elastic pre-tightening member 3;

[0044] A transparent protective sleeve 4, which is sleeved on the fastening sleeve 1;

[0045] The electronic tag body 5 is located between the transparent protective cover 4 and the fastening sleeve 1 , and is pressed and held on the outside of the fastening sleeve 1 by the transparent protective cover 4 .

[0046] By setting the elastic preload member 3 as described above, the fastening sleeve 1 can be stably connected to the outside of the optical cable, and relative sliding will not occur during laying and dragging; when movement is required, the larger elastic force can be overcome to move it, so that any number of fastening sleeves 1 can be installed on the optical cable 2 to meet the requirement of having electronic tags at both ends; optical cables without embedded intelligent passive electronic tags can be temporarily added or removed later, thereby facilitating the convenience of electronic tag removal and the requirement of stability without falling off during use.

[0047] This structural form is an external electronic tag, and the electronic tag can be removed and added as needed, which is more convenient than embedded intelligent passive electronic tags. It finally solves the problem that when using embedded intelligent passive electronic tags in the related technology, connector jumpers are added to both ends. Due to the different lengths of the jumpers, it cannot be guaranteed that there are electronic tags at both ends of the jumpers; and it is difficult to add intelligent electronic tags to the laid optical cables without embedded intelligent electronic tags at a later stage.

[0048] The transparent protective cover 4 not only plays a protective role, but also plays a role in allowing the naked eye to obtain information.

[0049] In some preferred embodiments, in order to facilitate the pressing of the electronic tag body 5 on the outside of the fastening sleeve 1, the transparent protective sleeve 4 is made of a transparent heat-shrinkable material; the heat-shrinkable feature allows for a perfect fit. However, there is no way to seal the two ends of the fastening sleeve 1, and it is also necessary to further strengthen the connection stability of the fastening sleeve 1 and the optical cable 2 after the connection, so the following settings are provided:

[0050] The length of the transparent protective sleeve 4 in the axial direction of the optical cable 2 is greater than the length of the fastening sleeve 1 in the axial direction of the optical cable 2;

[0051] The two ends of the transparent protective cover 4 in the axial direction of the optical cable 2 are used to be connected to the optical cable 2 after heat shrinkage.

[0052] Through the above arrangement, the heat-shrinkable transparent protective sleeve 4 seals the electronic tag body 5 between the fastening sleeve 1 and the transparent protective sleeve 4, so as to achieve tag protection, and the fixed tag will not slide on the optical cable 2, thereby enhancing stability. Such a structure and the elastic pre-tightening member 3 can also adapt to optical cables of different diameters, and can position and pre-clamp on the optical cable 2; due to the characteristics of elastic deformation under stress and heat shrinkage, it can adapt to optical cables 2 of different sizes.

[0053] Furthermore, in order to facilitate the control and positioning, the elastic preload member 3 is not eccentrically arranged and includes a plurality of elastic ribs distributed along the inner wall of the fastening sleeve 1 in the circumferential direction;

[0054] The axial length of the elastic rib is less than or equal to the axial length of the fastening sleeve 1 ; the elastic rib has a designed length in the radial direction of the fastening sleeve 1 .

[0055] In some preferred embodiments, reference Figure 3 The outer surface of the fastening sleeve 1 is provided with a circumferential receiving groove 100 for accommodating the electronic tag body 5; the fastening sleeve 1 is made of plastic material. The electronic tag body 5 can be connected to the circumferential receiving groove 100 by adhesive backing, and at the same time, the above structure ensures that the optical cable 2 is in the center of the fastening sleeve 1.

[0056] In some preferred embodiments, reference Figure 4 The electronic tag body 5 includes a flexible substrate 500, on which a rectangularly distributed antenna 501 is disposed, and on which a chip 502 connected to the antenna 501 is disposed;

[0057] A barcode area 503 and a serial number area 504 are provided on the flexible substrate 500 and located inside the rectangle;

[0058] The flexible substrate 500 is also provided with an indicator light 505 connected to the antenna 501 .

[0059] When the electronic tag is not invalid, it can be identified through the indicator light 505; when the electronic tag is invalid, the tag can be identified by the barcode; it can also be visually identified by the serial number to improve compatibility and apply to different situations.

[0060] In some preferred embodiments, there are specific requirements for the external dimensions and shape of the fastening sleeve 1:

[0061] In the first type, the inner passage of the fastening sleeve 1 is a cylindrical passage, and the outer contour of the cross section of the fastening sleeve 1 is a circle.

[0062] The second type is that the internal channel of the fastening sleeve 1 is a cylindrical channel, and the outer contour of the cross section of the fastening sleeve 1 is a polygon, each corner of the polygon is an arc angle, and the curvature radius of the arc angle is greater than the design value. The polygon is a triangle or a quadrilateral. Since the curvature radius of the arc angle is too small, it is easy to cause poor contact of the conductive glue at the chip or indicator light, and the label is invalid. In order to avoid excessive bending of the label at the indicator light and chip, the sleeve cross section is improved, such as a triangle, a quadrilateral, etc., and the bending radius at the indicator light is increased.

[0063] refer to Figure 5 The outer contour of the cross section of the fastening sleeve 1 is optimized. In this example, it is a triangular circle with large curvature radii on the three sides. The indicator lights and chip of the label are located on the three sides to avoid poor contact of the conductive glue at the chip or indicator light.

[0064] Through the above settings, the above electronic tags can meet the application of outdoor underground and overhead environments. The tags and optical cables are reliably fixed and will not slide relative to each other during laying and dragging. Tags can also be installed on laid optical cables.

[0065] The application also proposes a communication cable, which includes:

[0066] The optical cable 2 has an electronic tag on its outer side and at least one of its two ends is provided with a connector 6. The problem in the related art that when a jumper with a built-in intelligent passive electronic tag is used, connectors are added to both ends, and it is impossible to ensure that both ends of the jumper have electronic tags due to different lengths of the jumpers; and it is difficult to add intelligent electronic tags to the laid optical cable without the built-in intelligent electronic tag in the later stage.
