Problems solved by technology

[0006] However, there are certain defects in the current general-purpose cables
For example, with the continuous improvement of economic and social life, the power consumption has also increased significantly, so the input voltage to the cable has also increased step by step. Therefore, the temperature of the cable rises rapidly, causing the cable to be unable to withstand high temperatures and continue to heat up. burnt, thus greatly affecting the realization of the entire cable circuit
In addition, when the cable is connected to other lines, the cable access end needs to be peeled off, and the material covering the outer layer of the conductor in the existing cable is extremely difficult to peel off
In addition, the conductor is generally circular, and there are inevitably gaps between several conductors of the multi-core cable. When these conductors are extruded (wrapped) with insulating layers and sheaths, the conductors are extruded to form a wavy appearance. Greatly affects the feel and aesthetics of the cable

Embodiment Construction

[0024] Embodiments of the present invention will now be described with reference to the drawings, in which like reference numerals represent like elements. As described above, the present invention provides a multimedia data transmission system. The multi-core power cables are all made of high temperature resistant materials, which can ensure the safe operation of power signals. In addition, the second film layer enables the access end of the power cable to be easily peeled off when it is connected to other lines. In addition, the gaps between several conductors of the present invention are filled with fillers, which can ensure better roundness of the multi-core power cable of the present invention, and increase its hand feeling and aesthetic feeling.

[0025] Figure 1-2 An embodiment of the multimedia data transmission system of the present invention is shown. As shown in the figure, the power cable includes six conductors 110 , an insulating layer 120 , a filler 130 , a ...

Abstract

The invention discloses a multimedia data transmission system, which is characterized in that a multi-core power cable comprises a plurality of conductors, insulating layers coated on each of the conductors, a filling body, a first thin film layer, a copper braided layer, a glass fiber cloth layer, a second thin film layer and an outer covering layer; and the filling body is arranged in a gap among the conductors coated with the insulating layers and forms a cable core together with the conductors, and the first thin film layer, the copper braided layer, the glass fiber cloth layer, the secondthin film layer and the outer covering layer sequentially coat the cable core. The multi-core power cable disclosed by the invention is all made of high temperature resistant materials and can ensurethe safe operation of power signals. In addition, the second thin film layer makes convenience for an access end to be subjected to peeling treatment when the power cable is accessed to other circuits. Besides, the gap among the plurality of conductors is filled with the filling body, so that the power cable can be ensured to have good roundness, and the hand feeling and aesthetic feeling of thepower cable are increased. Meanwhile, the invention further discloses a method for manufacturing the multimedia data transmission system.

Description

technical field [0001] The invention relates to a power cable, and more particularly to a multimedia data transmission system and a manufacturing method thereof. Background technique [0002] At present, wires and cables have been widely used in industrial production, transportation, construction engineering and facilities, modern agriculture and scientific research, military equipment or military facilities, space, ocean detection, and have reached a ubiquitous state. With the step-by-step development of social and economic activities from depth to breadth, the varieties of wire and cable are constantly updated and improved, and the production volume continues to increase. For example, the construction of high-intelligence buildings requires computer network cables for hierarchical networking of hundreds or thousands of electronic computers; the establishment of urban public cable TV networks, the universal deposit and withdrawal of all banks in the city and even the countr...
