Embodiment Construction

[0043] The following is attached Figure 1-9 The application is described in further detail.

[0044] The embodiment of the present application discloses a coaxial cable arrangement. refer to figure 1 and figure 2 , the coaxial cable arrangement includes a plurality of cable units arranged side by side, and each cable unit includes a conductor 1, a fiber winding layer 2, a dielectric layer 3, an outer shielding layer 4, and a sheath layer 5 arranged in sequence from the inside to the outside. The sheath layers 5 of the two cable units are integrally connected.

[0045] refer to figure 1 and figure 2 , the conductor 1 is a single conductor of silver-plated copper-clad steel, the thickness of the silver-plated layer is between 1.5-3um, and the thickness of the silver-plated layer is preferably 2um here, and the conductor 1 has a higher transmission rate.

[0046] The fiber winding layer 2 can be wound on the conductor 1 by a single helix of fiber filaments capable of wit...

Abstract

The invention relates to a coaxial cable flat cable, an extrusion die head and a production process, and relates to the technical field of communication cables. The coaxial cable flat cable comprises at least two cable units arranged side by side, wherein each cable unit comprises a conductor and an insulating sheath layer, and the sheath layers of two adjacent cable units are integrally fixed; and the extrusion die head comprises a die body, one end of the die body is open and internally provided with a die cavity, the other end of the die body is provided with a die hole, the die hole comprises at least two communicated round holes, the number of the round holes is consistent with that of the cable units, and the aperture of the round holes is the same as the outer diameter of the outline of the sheath layer. The production process comprises the steps of manufacturing cable unit semi-finished products; enabling the plurality of cable unit semi-finished products to pass through an extrusion die head of a plastic extruding machine; and coating the surface of the cable unit semi-finished product passing through the extrusion die head with a sheath layer, and connecting the sheath layers of the plurality of cable units into a whole to form the cable flat cable after cooling. According to the invention, the advantage that multiple paths of signals can be transmitted for a long distance at the same time through one-time laying operation is achieved.

Description

technical field [0001] The application relates to the technical field of communication cables, in particular to a coaxial cable arrangement, an extrusion die and a production process. Background technique [0002] Coaxial cables have the characteristics of high frequency of use and strong resistance to external interference, so they are widely used in the interconnection and intercommunication between electronic devices. The insulating dielectric materials of coaxial cables are mainly polyethylene and polypropylene. With the development of the times, these two types of materials cannot meet the requirements in terms of temperature and frequency of use. Therefore, a new generation of coaxial cables that use fluoroplastics as insulating media Axial cables gradually replaced the old coaxial cables. [0003] For related technologies, please refer to the patent application number 201420090217.1 which discloses a fluoroplastic cable, which includes a cable core. The cable core in...
