Embodiment Construction

[0030] see figure 1 Shown is a first embodiment of the cable of the present invention. The cable 100 includes a core wire 10, a first shielding layer 15 covering the core wire 10, a second shielding layer 16 covering the first shielding layer 15, and the first shielding layer 15 and the second shielding layer. The two ground wires 18 between 16 and the outer coating layer 17 covering the second shielding layer 16 .

[0031] In this embodiment, the core wire 10 includes two pieces, which are abutted and parallel to each other and extend in the longitudinal direction. The core wire 10 includes two inner conductors 11 , and the two inner conductors 11 are separately covered with insulation. Layer 12, the insulating layer 12 is covered with a sheath layer 13 extruded at the same time. The sheath layer 13 tightly wraps the core wire 10, so that the two core wires are abutted and parallel, which can effectively reduce the attenuation in the process of signal transmission. The str...

Abstract

The invention discloses a cable which comprises a core wire, a first shielding layer wrapping the core wire, a second shielding layer wrapping the first shielding layer and an outer coating layer wrapping the second shielding layer, the core wire comprises two inner conductors, and the two inner conductors are respectively and independently covered with an insulating layer. And a sheath layer which is simultaneously extruded and molded covers the insulating layer, and the sheath layer wraps the core wires, so that the core wires are propped against each other and are parallel to each other. The sheath layer compactly wraps the core wire group, the conductor spacing is smaller, the cable structure is more compact, and the shielding layer can realize full shielding, so that the signal attenuation can be effectively reduced, the signal integrity is ensured, and the distortion resistance of the cable is also enhanced.

Description

【Technical field】 [0001] The present invention relates to a cable, in particular to a low-loss high-speed signal cable for transmitting high-frequency signals. 【Background technique】 [0002] With the rapid development of the Internet era, the rise of big data and the Internet of Things has driven the rapid growth of the demand for high-speed and high-frequency signal cables. However, in the process of high-frequency and high-power signal transmission, cables are easily interfered by external electromagnetic signals. , the stable and effective transmission of the signal cannot be guaranteed. [0003] Therefore, it is necessary to provide a high-speed signal cable with low loss, high transmission rate, good anti-torsion performance, and simple manufacture. [Content of the invention] [0004] The main purpose of the present invention is to provide a high-speed signal cable with low loss, high transmission rate and good anti-twist performance. [0005] In order to achieve t...
