Embodiment Construction

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0023] refer to Figure 1-3 , a low-noise coaxial cable with high moisture-proof performance, including a twisted body 1, the twisted body 1 includes an inner conductor 101, an inner insulating layer 102, an electromagnetic shielding layer 103 and a current guide wire 104, and the inner conductor 101 is specifically a multi-strand plated The center of the tin-copper conductor is twisted with steel as the core. The guide wire 104 is made of multi-strand aluminum-zinc mixed material. The two inner conductors 101 are twisted into one strand, and the outer side of the inner conductor 101 is wrapped with an inner insulating layer. 102, the outer side of the inner insulati...

Abstract

The invention relates to the technical field of cables, in particular to a low-noise coaxial cable with high moisture-proof performance. The low-noise coaxial cable comprises twisted bodies, of whicheach comprises inner conductors, inner insulating layers, an electromagnetic shielding layer and a guide wire. Every two inner conductors are twisted as a stand, and the outer sides of the inner conductors are wrapped with the inner insulating layers respectively. The outer sides of every two inner insulating layers are wrapped with one electromagnetic shielding layer. Each guide body is interspersed between the inner insulating layers and the electromagnetic shielding layer of one twisted body. The outer side of the electromagnetic shielding layers is glued with a waterproof layer. A reinforcing core is interspersed on the central axis of the waterproof layer. The gap between the inner wall of the waterproof layer and the electromagnetic shielding layers is filled with sound insulation filler. The low-noise coaxial cable of the invention has the advantages of small transmission attenuation value and high transmission rate in a heavier environment, water and moisture prevention, soundinsulation and noise reduction, stable current, cost saving, and the like.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a low-noise coaxial cable with high moisture-proof performance. Background technique [0002] With the development of society, more and more cables are used, and the application fields are more and more extensive, and the requirements for cable types and performance are also getting higher and higher. It is composed of plastic and rubber organic polymers. When used in some environments, the protection of the wire core is not enough, especially under external pressure, it is easy to damage the wire core. In order to increase the strength of the cable, an armor layer is often added. Improve the compression resistance of the cable, but the general armor layer is not only heavy, but also has gaps, does not have the function of moisture resistance, and cannot be used in a humid environment. Such cables are prone to rust in a humid environment, resulting in reduced durability , thereby...
