Description

Quincuncial core wire for high-speed cable

Technical Field

The utility model relates to a quincuncial core wire for a high-speed cable, which can effectively improve the signal transmission capability of a cable core and the bending resistance effect of the cable core, and belongs to the field of core wire manufacturing.

Background

US202017033595A entitled "cable", the main object of the present utility model is to provide a cable with good shielding effect and stable signal transmission capability. To achieve the above object, a cable includes: a core wire including an inner conductor and an insulating layer surrounding the inner conductor by extrusion molding; a shielding layer covering the core wire; an outer insulating layer covering the shielding layer; wherein the shielding layer is silver-plated copper foil, and an insulating layer is not arranged between the core wire and the silver-plated copper foil. Compared with the prior art, the utility model has the advantages that the silver-plated copper foil is used as the shielding layer to increase the shielding effect of the signal cable, thereby protecting the signal cable from external interference when transmitting signals, and simultaneously ensuring the reliability of signal transmission. The utility model only adopts silver-plated copper foil as a shielding layer, so that the shielding effect of the signal cable is enhanced, but the capacity of transmitting signals to the cable core is not improved, and meanwhile, the mechanical strength of the cable core is not improved.

Disclosure of Invention

The design purpose is as follows: the plum blossom core wire for the high-speed cable, which can not only effectively improve the bending resistance of the core wire, but also effectively improve the transmission efficiency of the core wire, is designed to avoid the defects in the background art.

The design scheme is as follows: to achieve the above design objective. The utility model is structurally designed: 1. the design of the cross section of the cable core wire into a plum blossom-shaped structure (see fig. 1) is one of the technical characteristics of the utility model. The purpose of this design is: when the cable core wire surface (in the longitudinal direction) is in a plum blossom-shaped structure, a plurality of reinforcing ribs (plum blossom petals) are arranged on the equivalent cable core wire surface, and the reinforcing ribs can effectively improve the mechanical strength of the core wire, and the longitudinal groove parts between the reinforcing ribs also provide space for bending the cable core wire, so that the cable core wire has good bending resistance. 2. The design that the width of the concave arc part is larger than that of the plum blossom valve is a second technical feature of the utility model. The purpose of this design is: when the width of the concave arc opening is larger than that of the convex arc part, the quincuncial insulating sheath wires can be prevented from being formed by the two core wire insulating sheaths, and when the cables (cables) are formed by the plurality of the quincuncial insulating sheath wires, the cables can be arranged in a staggered manner, so that the variety (or the diameter) of the assembled cables is reduced.

The technical scheme is as follows: the plum blossom core wire for the high-speed cable comprises a cable core wire, wherein the cross section of the cable core wire is of a plum blossom-shaped structure, and a concave arc part is arranged between plum blossom petals and plum blossom petals in the plum blossom-shaped structure.

Compared with the background technology, the utility model not only can completely meet and exceed the technical requirements of the wire cores required by the high-speed cables, but also has strong capability of high-speed data signals; secondly, the mechanical property is very excellent, the bending resistance and the bending resistance effect are very excellent, the coating layer is broken in the test, and the cable core wire is not broken.
