Description
Technical Field
The utility model relates to a shield technical field on the cable low frequency transmission line specifically is a novel structure that improvement wire rod low frequency was crosstalked.
Background
Because the low-frequency signal transmission cable in the existing cable is not shielded, when an electric signal passes through a conductor in an insulation, the conductor can generate a magnetic field surrounding the conductor; when the conductor inside the insulation is a stranded conductor, the stranded conductor can be regarded as a section of wound coil, namely an inductor, and when a magnetic field surrounding the conductor passes through the inductor, a current opposite to an original electric signal flows on the conductor, so that the transmission of the original electric signal on the conductor is interfered; nowadays, more and more products such as USB 3.2, USB 4, TB3 wires and the like have more and more strict requirements on low-frequency signal crosstalk, so at present, improvement on low-frequency transmission crosstalk is imperative.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a novel structure of improvement wire rod low frequency crosstalk to solve the problem of proposing among the above-mentioned background art.
In order to solve the technical problem, the utility model provides a following technical scheme: the utility model provides a novel structure that improvement wire rod low frequency was crosstalked, includes that power cord, first shield layer, outer protective sheath, high frequency signal transmission cable, low frequency signal transmission cable and second shield the layer, it has first shielding layer to peg graft on one side inner wall of outer protective sheath, it has high frequency signal transmission cable to distribute to peg graft on one side inner wall of layer first, it has low frequency signal transmission cable to distribute to peg graft on one side outer wall that corresponds high frequency signal transmission cable on one side inner wall of layer first, it shields the layer to have cup jointed the second on one side outer wall of low frequency signal transmission cable, it has the power cord to peg graft on one side outer wall that corresponds high frequency signal transmission cable on one side inner wall of layer first.
The outer wall of the power line is of an insulating rubber structure.
The first shielding layer is of a double-layer winding structure.
The number of the high-frequency signal transmission cables is ten, and the number of the low-frequency signal transmission cables is four.
Compared with the prior art, the utility model discloses the beneficial effect who reaches is: the utility model discloses a, simple structure, convenient to use covers the connected mode on layer through the outer cladding second of low frequency signal transmission cable, has realized the purpose of crosstalk shielding between the cable low frequency transmission, can effectually prevent mutual crosstalk between the low frequency transmission cable, and this second shields the layer and does not confine to the metal material, can be replaced by the metal that reaches 100% shield the coverage and non-metallic combination material or non-metallic conductive material, is convenient for satisfy the different demands of customer.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: a novel structure for improving low-frequency crosstalk of wire rods comprises a power wire 1, a first shielding layer 2, an outer protective sleeve 3, a high-frequency signal transmission cable 4, a low-frequency signal transmission cable 5 and a second shielding layer 6, wherein the first shielding layer 2 is inserted on the inner wall of one side of the outer protective sleeve 3, the high-frequency signal transmission cable 4 is inserted and connected on the inner wall of one side of the first shielding layer 2, the low-frequency signal transmission cable 5 is inserted and connected on the outer wall of one side, corresponding to the high-frequency signal transmission cable 4, of the inner wall of one side of the first shielding layer 2, the second shielding layer 6 is sleeved and connected on the outer wall of one side of the low-frequency signal transmission cable 5, and the power wire 1 is inserted and connected on the outer wall of one side, corresponding to the high-; the outer wall of the power line 1 is of an insulating rubber structure, and the insulating rubber structure achieves the insulating purpose and is convenient to use without changing the original structures and performances of OD, softness, swing and the like of the wire; the first shielding layer 2 is of a double-layer winding structure, so that the protection is facilitated; the quantity of high frequency signal transmission cable 4 is ten, and the quantity of low frequency signal transmission cable 5 is four, and the signal transmission of being convenient for is used in a plurality of high frequency signal transmission cables 4 and the cooperation of low frequency signal transmission cable 5.
When using the novel structure of improvement wire rod low frequency crosstalk, the one deck second of cladding shields layer 6 on the outer wall of low frequency signal transmission cable 5, this second shields layer 6 and can uses the metal to close frequently, but this metal shields thickness can not exceed 12um, in order to guarantee not to change the original OD of wire rod, the compliance, sway isotructure and performance, this second shields layer 6 also can adopt nonmetal or nonmetal and metal combined material, through the shielding structure to cladding on the 5 outer walls of low frequency signal transmission cable, make low frequency signal in the transmission process because the electromagnetic interference that electric current and vortex produced can be absorbed by the metal of shielding layer, thereby reach the purpose of the low frequency crosstalk of improvement cable.
