Problems solved by technology

[0004] In the existing technology, such as figure 1 As shown, the inner shielding layer 3 of the coaxial cable is currently used in the industry to wind the copper tape in one direction. As a result of the one-way winding, the winding layer of the inner shielding layer will change Partial looseness, which leads to instability of the third-order intermodulation performance of the cable and affects the transmission performance of electrical signals

Embodiment Construction

[0024] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] Such as figure 2 and 3 As shown, the coaxial cable with stable third-order intermodulation performance includes an inner conductor 1, and the outer side of the inner conductor 1 is sequentially covered with an insulating layer 2, an inner shielding layer 3, an outer shielding layer 4 and a sheath 5, and the inner shielding layer 3 It is made of conductive tape cross braided; in this embodiment, the inner conductor 1 is used for the transmission of electrical signals, the sheath 5 is used as the outermost protection of the coaxial cable, and the inner shielding layer 3 is made of conductive tape cross braided. The formed structure makes the inner shielding layer of the cable not partially loose no matter in the state of bending / straightening / vibration, thus ensuring that the coaxial cable has stable and good...

Abstract

The invention provides a coaxial cable with stable order intermodulation performance, which comprises an inner conductor, the outer side of the inner conductor is sequentially sleeved with an insulating layer, an inner shielding layer, an outer shielding layer and a sheath, and the inner shielding layer is formed by weaving conductive bands in a crisscross manner; and according to the invention, the structure of the inner shielding layer is creatively changed, and unidirectional winding is changed into bidirectional alternate weaving, so that the inner shielding layer of the cable cannot be locally loosened in a bending / straightening / vibrating state, and the coaxial cable has stable and good three-order intermodulation performance.

Description

technical field [0001] The invention belongs to the technical field of coaxial cables, and in particular relates to a coaxial cable with stable third-order intermodulation performance. Background technique [0002] Third-order intermodulation (Third Order Intermodulation or 3rd Order IMD) means that when two signals are in a linear system, due to nonlinear factors, the second harmonic of one signal is beat by the fundamental wave of the other signal (mixing frequency) generated after the spurious signal. [0003] The name of the coaxial cable is related to its structure. Coaxial cables are also one of the most common transmission media in LANs. The pair of conductors it uses to transmit information is selected according to the structure that a cylindrical outer conductor is set outside the inner conductor (a thin core), and the two conductors are separated from each other by insulating materials. The outer conductor and The center of the central axis core line is on the s...
