The main structural types include parallel double conductors, parallel multi-conductors, coaxial lines, strip lines, and microstrip lines working in quasi-TEM mode, all of which can be analyzed by means of a simple double conductor model. Various waveguides that transmit TE mode, TM mode, or their mixed modes can be considered as generalized transmission lines. The distribution law of the electromagnetic field in the waveguide along the propagation direction is similar to that of the voltage and current on the transmission line, and can be analyzed from the perspective of an equivalent transmission line.

However, the traditional single metal shield wrapping structure is unstable and has poor attenuation retention. Although the traditional single metal shield longitudinal package structure has good structural stability, it also has poor attenuation improvement. Therefore, how to ensure the structural stability of the cable and improve the attenuation of the data line to the signal is a problem that people in this field need to consider.

The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] See also Figure 1A high-frequency data transmission line includes: a core component 100, a shielding tape 200, a grounding component 300 and a folded sleeve 400. It should be noted that the core component 100 is used to transmit high-frequency signals; the shielding tape 200 is used to shield interference signals; the grounding component 300 is used to achieve grounding; and the folded sleeve 400 is used to further achieve a shielding effect.

[0031] See also Figure 1 The wire core assembly 100 includes a plurality of transmission cores 110, each of which is arranged in parallel with each other, and the outer side walls of each adjacent transmission core 110 are in close contact. It should be noted that by arranging the transmission cores in parallel with each other, the transmission stability and reliability of the high-frequency signal can be guaranteed, and since they are in direct close contact and parallel arrangement, it is convenient to process the high-frequency data transmission line, meet various processing requirements, and greatly improve the promotion.

[0032] See also Figure 1 , the shielding tape 200 is longitudinally wrapped around the outside of each transmission core wire 110 along the extension direction of each transmission core wire 110, and the inner side wall of the shielding tape 200 is tightly fitted with the outer side wall of each transmission core wire 110. It should be noted that the shielding tape 200 is longitudinally wrapped around each transmission core wire 110, which can shield the interference of the outside world on the core wire when transmitting high-frequency signals, and at the same time, it can also avoid the interference of the ground wire on the transmission core wire 110, so that the distortion of the signal during high-frequency transmission is minimized, and the problem of bit error is avoided, which further improves the stability and reliability of the high-frequency data transmission line, and can also improve the signal transmission capacity of the high-frequency data line, and maintain the stable physical structure and electrical performance of the high-frequency data transmission line.

[0033] See also Figure 1 , the grounding assembly 300 includes at least one ground wire 310, each of the ground wires 310 is respectively arranged in parallel with each of the transmission core wires 110, and each of the ground wires 310 is respectively tightly attached to the outer wall of the shielding tape 200. It should be noted that in this embodiment, two ground wires are provided, and the two ground wires are respectively arranged on the left and right sides of the shielding tape 200, and the ground wires located on the left and right sides are respectively arranged in parallel with the transmission core wires 110. Further, while the shielding tape is longitudinally wrapped around the two transmission core wires, the two ground wires are fixed in parallel on the outer wall of the shielding tape. Since the two ground wires are symmetrically placed on both sides of the wire, not only can the shielding balance of the high-frequency data transmission line be further enhanced, but also the processing and assembly of the high-frequency data transmission line can be facilitated, and at the same time, the transmission performance of the high-frequency data transmission line can meet the requirements of high frequency (≧25GHz), that is, the signal attenuation of the high-frequency data transmission line is reduced.

[0034] It should be noted that the grounding assembly includes two ground wires 310, and the two ground wires 310 are respectively arranged in parallel with each of the transmission core wires, and the two ground wires are respectively tightly attached to the outer side walls of the shielding tape. In this embodiment, the two ground wires are respectively arranged outside the two side edges of the shielding tape. In this way, the structural stability of the high-frequency data transmission line and the effectiveness of the shielding can be guaranteed.

[0035] See also Figure 1 , the folded sleeve 400 is spirally wound around the shielding tape 200 and each of the ground wires 310. It should be noted that the folded sleeve is wrapped around the shielding tape 200 and each of the ground wires 310 in a transverse wrapping form, which can not only fix the ground wire on the outer wall of the shielding tape 200, but also improve the structural stability of the entire high-frequency data transmission line. In this embodiment, the folded sleeve fixes the two ground wires on the left and right sides of the shielding tape respectively, which can ensure the symmetry of the entire high-frequency data transmission line, further strengthen the balance of the shielding, and improve the shielding effect of the high-frequency data transmission line.

[0036] In this way, by providing the shielding tape for longitudinal wrapping and the folded sleeve for wrapping, it is possible to take into account both the effective shielding of the electromagnetic field by the longitudinal wrapping and the good characteristics of the softness of the wrapping structure, while increasing the shielding effect without reducing the bending radius of the wire. At the same time, the two ground wires are respectively arranged on the left and right sides of the shielding tape, so as to strengthen the balance of the shielding and improve the shielding effect, and also simplify the operation during assembly and facilitate processing; at the same time, the symmetrically arranged ground wires and transmission core wires can improve the transmission performance of the data transmission line and reduce the attenuation and distortion of signal transmission.

[0037] It should be noted that the wire core assembly includes two transmission core wires, the two transmission core wires are arranged in parallel, and the outer side walls of the two transmission core wires are in close contact, so as to improve the stability and efficiency of data transmission.

[0038] It should be noted that, in one of the transmission core wires 110, the transmission core wire 110 includes an insulating rubber layer 111 and a conductor 112, wherein the insulating rubber layer 111 is coated on the outside of the conductor 112, and the outer wall of the insulating rubber layer 111 is in close contact with the inner wall of the shielding tape 200. The insulating rubber layer 111 is used to wrap the conductor and achieve an insulation effect; the conductor is used to transmit high-frequency data and signals. In this way, by providing the insulating rubber layer 111, two adjacent conductors can be prevented from being connected to each other, and at the same time, it can also play a certain role in isolation and shielding, and can also protect the conductor from damage.

[0039] See also Figure 2, the high-frequency data transmission line also includes a protective component 500, and the protective component 500 is coated on the outside of the folded sleeve 400. In this embodiment, the protective component 500 includes at least one layer of protective tape, and each of the protective tapes is sequentially coated on the outside of the folded sleeve. Preferably, the protective tape is a hot-melt Mylar tape. It should be noted that the protective component 500 is used to protect the wire from damage. At the same time, when coating, it can further tighten the structural stability and compactness of each transmission core wire 110, each wire 310, shielding tape 200 and folded sleeve 400, and further improve the structural stability of the high-frequency transmission data line.

[0040] Please refer again Figure 1 The high-frequency data transmission line further includes a printing layer 600, and the printing layer 600 is attached to the folded package 400. The printing layer is used for marking.

[0041] It is understandable that the traditional single wrapping structure is unstable and has poor attenuation retention. Although the longitudinal wrapping structure has better structural stability than the single wrapping structure, its attenuation improvement and structural stability are inferior to the longitudinal wrapping metal shield plus the wrapping folded metal shield. Therefore, in order to improve the structural stability of high-frequency data transmission lines, reduce the attenuation of signal transmission, and improve the signal shielding effect of high-frequency data transmission lines, for example, please refer to Figure 3 The folded sleeve 400 is formed by folding the shielding layer 410, and the shielding layer 410 is spirally wound and wrapped around the shielding tape 200 and each of the ground wires 310. In this way, by providing the folded shielding layer, the structural stability of the high-frequency data transmission line can be effectively improved after the folding, the attenuation of the signal transmission can be reduced, and the signal shielding effect of the high-frequency data transmission line can be improved.

[0042] For further information, see Figure 3 The shielding layer 410 is provided with a conductive surface 411 and a non-conductive surface 412. After being folded in half, the first shielding area and the second shielding area are separated along the folding line. The non-conductive surface 412 on the first shielding area and the non-conductive surface 412 on the second shielding area are attached to form a folded wrapping tape, which is wrapped in the form of a horizontal wrapping around the shielding wrapping tape 200 and each of the ground wires 310. In this way, after the folded shielding layer is provided, the conductive surface faces outward when folded in half, and then can be connected to each other after wrapping, so that the electromagnetic field is further shielded, and the shielding effect of the folded wrapping is further improved.

[0043] It should also be noted that the protective tape is wrapped around the folded sleeve in a spiral winding manner, and the direction of the spiral winding is opposite to the direction of the spiral winding of the folded sleeve. That is, when the spiral winding direction of the folded sleeve is clockwise, the spiral winding direction of the protective tape is counterclockwise, thereby further improving the structural stability of the high-frequency data transmission line.

[0044] It can be understood that when wrapping the protective tape of the high-frequency data transmission line, there will be a certain overlap, and there will be a certain level of unevenness between the overlapping protective tape and the non-overlapping protective tape, so this will cause the high-frequency data transmission line to be uneven and asymmetrical; and, since the overlapping protective tape has one more layer of protective tape than the non-overlapping protective tape, this will also result in a poor shielding effect; at the same time, since the overlapping protective tape is higher than the non-overlapping protective tape, there is a fine gap between the overlapping protective tape and the non-overlapping protective tape, and these fine gaps will be magnified after the high-frequency data transmission line is bent, wound or pulled, that is, the gap of the protective tape will be increased, thereby reducing the stability of its structure and reducing its high-frequency data transmission performance; therefore, in order to avoid the problem of unevenness when wrapping the protective tape, that is, to avoid the height difference between the overlapping protective tape and the non-overlapping protective tape, it is ensured that the high-frequency data transmission line has a flat and symmetrical structure; and, in order to avoid the overlapping part The problem that the shielding effect of the protective tape with one more layer is poorer than that of the protective tape without overlapping parts, and at the same time, in order to avoid a slight gap between the overlapping protective tape and the non-overlapping protective tape, the stability of the high-frequency data transmission line structure is improved and the high-frequency data transmission performance of the high-frequency data transmission line is reduced; in one embodiment, for example, the protective component also includes a wrapped thickened glue layer and an adhesive layer, the adhesive layer is attached to the protective tape, and the wrapped thickened glue layer is attached to the side of the adhesive layer away from the protective tape. When the When the protective tape is spirally wound on the folded sleeve, the wrapped thickened adhesive layer is arranged on the position of the protective tape in the overlapping part of the spiral winding; the wrapped thickened adhesive layer includes a first overflow adhesive portion, a second overflow adhesive portion and a hot melt connection portion, the hot melt connection portion has a first connection end and a second connection end, the first connection end of the hot melt connection portion is connected to the first overflow adhesive portion, and the second connection end of the hot melt connection portion is connected to the second overflow adhesive portion; the wrapped thickened adhesive layer is a glue layer, and the first overflow adhesive portion and the second overflow adhesive portion are respectively located on both sides of the hot melt connection portion.In this way, by providing a wrapping thickened glue layer, and providing a first overflow glue portion, a second overflow glue portion and a hot-melt connection portion on the wrapping thickened glue layer, the problem of uneven height during wrapping of the protective tape can be avoided, that is, the height difference between the overlapping protective tape and the non-overlapping protective tape can be avoided, thereby ensuring that the high-frequency data transmission line has a flat and symmetrical structure; and the problem of poor shielding effect due to the overlapping protective tape having one more layer of protective tape than the non-overlapping protective tape can be avoided. At the same time, the appearance of a fine gap between the overlapping protective tape and the non-overlapping protective tape can be avoided, thereby improving the stability of the high-frequency data transmission line structure and reducing the high-frequency data transmission performance of the high-frequency data transmission line.

[0045] In order to better explain and illustrate the above-mentioned wrapping thickening adhesive layer, so as to better understand the concept of the above-mentioned wrapping thickening adhesive layer. Figure 4 As shown, the protective component also includes a wrapping thickened adhesive layer 700 and an adhesive layer 800, the adhesive layer is attached to the protective tape, and the wrapping thickened adhesive layer 700 is attached to a side of the adhesive layer away from the protective tape. When the protective tape is spirally wound on the folded sleeve, the wrapping thickened adhesive layer 700 is arranged at the position of the protective tape at the overlapping part of the spiral winding. It should be noted that the wrapping thickened adhesive layer 700 is a commonly used glue on the market, and is used to attach the overlapping part of the protective tape. After heating, the protective tape is more stable and no gaps will appear.

[0046] The wrapping thickened glue layer 700 includes a first overflow glue part 710, a second overflow glue part 720 and a hot melt connection part 730, wherein the hot melt connection part 730 has a first connection end and a second connection end, wherein the first connection end of the hot melt connection part 730 is connected to the first overflow glue part 710, and the second connection end of the hot melt connection part 730 is connected to the second overflow glue part 720; the wrapping thickened glue layer is a glue layer, wherein the first overflow glue part and the second overflow glue part are respectively located on both sides of the hot melt connection part. It should be noted that the first overflow glue part 710 is used to overflow on one side of the protective tape after heating, and the second overflow glue part 720 is used to overflow on the other side of the protective tape after heating, and the hot melt connection part 730 is used to connect the first overflow glue part 710 and the second overflow glue part 720.

[0047] By providing a wrapped thickened adhesive layer on the adhesive layer, when the protective tape is wound, due to the presence of the wrapped thickened adhesive layer, after the wire is heated, the wrapped thickened adhesive layer on the protective tape is squeezed after winding, that is, the wrapped thickened adhesive layer will overflow to both sides, that is, the first overflowing adhesive portion will overflow to the outside of the protective tape after heating and pressurization, so that the side where a slight gap appears between the overlapping protective tape and the protective tape without overlapping portion in the traditional method can be filled with glue, that is, the first overflowing adhesive portion is filled on the side where a slight gap appears between the overlapping protective tape and the protective tape without overlapping portion; similarly, at the overlapping portion The other side of the slight gap between the overlapping protective tape and the non-overlapping protective tape will also be filled with glue, that is, the other side of the slight gap between the overlapping protective tape and the non-overlapping protective tape will be filled with the second overflow glue portion, which can avoid the problem of poor shielding effect due to the overlapping protective tape having one more layer than the non-overlapping protective tape, and by providing the first overflow portion and the second overflow portion, it can be avoided that there is no gap between the overlapping portion and the non-overlapping portion, and the structure of the wire will not be damaged after the wire is bent, wrapped or pulled, thereby improving the stability of the structure, and then improving the performance of high-frequency data transmission.

[0048] It should also be noted that after the hot-melt connection part is heated and extruded, due to the extrusion force, the hot-melt connection part will also expand its area to both sides, so that the hot-melt connection part is connected to the first overflow glue part and the second overflow glue part on both sides, and because the first overflow glue part, the second overflow glue part and the hot-melt connection part are extruded at the same time, the problem of unevenness when wrapping the protective tape can be avoided, thereby ensuring that the high-frequency data transmission line has a flat and symmetrical structure; further, after heating and extrusion, the first overflow part and the second overflow part can be extended outward, so that the first overflow part and the second overflow part are in close contact with each other to form a glue layer, that is, when the first overflow part and the second overflow part are heated and pressurized, the first overflow part on one side of the protective tape can be connected to the second overflow part of the outer tape adjacent to the protective tape, and in close contact, thereby further avoiding the problem of unevenness of the high-frequency data transmission line, and further ensuring that the high-frequency data transmission line has a flat and symmetrical structure.

[0049] In this way, by providing a wrapping thickened glue layer, and providing a first overflow glue portion, a second overflow glue portion and a hot-melt connection portion on the wrapping thickened glue layer, the problem of uneven height during wrapping of the protective tape can be avoided, that is, the height difference between the overlapping protective tape and the non-overlapping protective tape can be avoided, thereby ensuring that the high-frequency data transmission line has a flat and symmetrical structure; and the problem of poor shielding effect due to the overlapping protective tape having one more layer of protective tape than the non-overlapping protective tape can be avoided. At the same time, the appearance of a fine gap between the overlapping protective tape and the non-overlapping protective tape can be avoided, thereby improving the stability of the high-frequency data transmission line structure and reducing the high-frequency data transmission performance of the high-frequency data transmission line.

[0050] The advantages and beneficial effects of the present invention compared to the prior art are as follows:

[0051] The present invention is a high-frequency data transmission line. By providing a shielding tape for longitudinal wrapping and a folded sleeve for wrapping, the effective shielding of the electromagnetic field by the longitudinal wrapping is taken into consideration, and the good characteristics of the softness of the wrapping structure are also taken into consideration. While increasing the shielding effect, the bending radius of the wire is not reduced. At the same time, two ground wires are respectively arranged on the left and right sides of the shielding tape, so that the balance of the shielding can be strengthened, the shielding effect can be improved, and the operation during assembly can be simplified, which is convenient for processing; at the same time, the symmetrically arranged ground wires and transmission core wires can improve the transmission performance of the data transmission line and reduce the attenuation and distortion of signal transmission.

[0052] The above-mentioned embodiments only express several embodiments of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
