Embodiment Construction

[0014] Such as figure 1 As shown, a twinaxial or differential cable according to the first embodiment of the present invention includes a pair of core wires that are not entangled with each other. Each core wire is provided with a conductor 1 covered in an insulating layer 2, an insulating inner tape 4 wrapped around the pair of core wires, and a shielding tape 5 longitudinally wrapping the insulating inner tape 4, located on the outward side of the shielding tape 5 and located at the The grounding wire 3 on the center line between the cables, and the insulating outer tape 6 spirally wrapping the shielding tape 5 and the grounding wire 3 with the outer insulating tape 6 . The shielding strip 5 includes an insulating inner layer and a conductive outer layer. A technical feature of the present invention is that the seam of the longitudinally wound shielding tape 5 is located on the other side of the shielding tape 5 opposite to the ground wire 3, and this position is along the ...

Abstract

A cable includes a pair of wires, an insulative inner tape spirally wrapping the pair of wires, a shielding tape longitudinally wrapping the insulative inner tape, a ground wire positioned outside ofthe shielding tape and at a centerline between the pair of wires, and an insulative outer tape spirally wrapping both the shielding tape and the ground wire. Each wire comprises an insulating layer with a conductor. The shielding tape comprises an insulating inner layer and a conductive outer layer wrapping the insulating inner layer.

Description

【Technical field】 [0001] The present invention relates to a cable, in particular to a twinaxial cable for data transmission with a data transmission rate exceeding 10 Gbps. 【Background technique】 [0002] Traditional twinaxial cables for 10Gbps+ data transmission typically have about 5% coupling. Dual extrusion is an existing method to increase the coupling percentage of twinax cables. However, this approach cannot be developed for single insulated conductors relying on readily available in-line electronic process control. US Patent Nos. 5,142,100, 8,981,216 and 9,123,452 disclose some related designs. [0003] Therefore, there is a need for an improved twinaxial cable to overcome the deficiencies of the prior art. 【Content of invention】 [0004] The main purpose of the present invention is to provide a twinaxial cable with signal pair coupling of 7%-14% and relatively reduced signal power loss. [0005] In order to solve the above-mentioned technical problems, the pre...
