a coaxial cable

Abstract

The invention discloses a coaxial cable. The coaxial cable comprises a conductive body, a foamed insulating layer, an outer conductor layer, a fiber sleeve and an insulating layer which are arranged from inside to outside in sequence, wherein the fiber sleeve is provided with a framework with frame holes; the framework is made from second fibers in a fusing manner; the framework is fixedly connected with the outer conductor layer and the insulating layer; first fibers are alternately inserted in the frame holes; and the first fibers are connected mutually to form a net shape. The coaxial cable provided by the invention adopts the framework structure made from the second fibers, and the fiber sleeve woven by the first fibers woven with metal wires, so that the coaxial cable is simple in structure, good in shock absorption effect, and relatively high in bending and stretching resistance; due to the fiber material, the metal wires can be woven conveniently, so that the coaxial cable protective layer has a relatively good shielding effect, the cost of the overall cable is relatively low, the weight of the cable is relatively low, and the cable obtains a higher economic effect; and due to the fiber material, the chemical performances of the coaxial cable protection layer can be expanded and improved conveniently.

Description

technical field

[0001] The invention relates to the field of cable production, in particular to a coaxial cable. Background technique

[0002] Coaxial cables can be divided into two basic types, baseband coaxial cables and broadband coaxial cables. At present, the baseband is a commonly used cable, and its shielding wire is a mesh made of copper, with a characteristic impedance of 50 (such as RG-8, RG-58, etc.); the shielding layer of the cable commonly used in broadband coaxial cables is usually made of aluminum. Stamped, the characteristic impedance is 75 (such as RG-59, etc.).

[0003] Coaxial cables can be divided into thick coaxial cables and thin coaxial cables according to their diameters. The thick cable is suitable for a relatively large local network. It has a long standard distance and high reliability. Since the cable does not need to be cut during installation, the network access position of the computer can be flexibly adjusted according to the needs. However...

Embodiment 1

[0026] Embodiment 1: The embodiment of the present invention discloses a coaxial cable (see attached figure 1 , 2 , 3, 4), including: conductor 1, foam insulation layer 2, outer conductor layer 3, fiber sheath 5, insulation layer 6, said conductor 1, foam insulation layer 2, outer conductor layer 3, fiber sheath 5. The insulating layer 6 is arranged sequentially from the inside to the outside. The fiber sleeve 5 is provided with a skeleton 7 with frame holes 8. The skeleton 7 is made by melting the second fiber 52. The skeleton 7 is fixedly connected to the outer conductor layer 3 and the insulating layer 6, the first fibers 51 are interspersed in the frame holes 8, the first fibers 51 are braided with metal wires, and the first fibers 51 are interlinked to form a net. In the present invention, the second fiber 52 is used to make the skeleton 7 structure and the fiber sleeve 5 woven by the first fiber 51 braided with metal wires has a simple structure, good shock absorption e...

Embodiment 2

[0031] Embodiment 2: The melting temperature of the second fiber 52 is 150°C. The outer surface of the outer conductor layer 3 facing the fiber sleeve 5 is provided with a heat-insulating and corrosion-resistant coating film 4, and the fiber material with a melting temperature of 100°C-150°C has a lower melting temperature, and the heat required for melting is lower. When external hot air is used for heating, the heat-insulating and corrosion-resistant coating film effectively blocks the influence of heat transfer on the foam insulation, effectively reducing the difficulty of the production process.

[0032] The insulating layer 6 has a thickness of 5 mm. The 2mm-5mm polyethylene insulation layer is mainly used for waterproofing and penetration of the coaxial cable. It does not need the insulation layer 6 to have a greater impact on the physical properties of the coaxial cable such as shock absorption. It only needs a thickness of 2-5mm to achieve Anticipated requirements, it...
