Problems solved by technology

However, the improvements made to the HDMI cable in the prior art are mainly limited to the stability of the structure, short-circuit prevention, attenuation reduction, etc., and there is no substantial improvement in the improvement of the signal transmission quality.
In addition, the electronic wires and signal wires in the existing HDMI cables are all 24 wires (that is, the diameter is 0.511mm). The overall thickness of the cable makes it extremely uncoordinated when used with some small electronic devices.

Embodiment 1

[0026] see figure 2 , the HDMI cable provided in this embodiment includes: five-strand coil 1, four PE wires 2, one peripheral ground wire 3, aluminum foil 4, braiding layer 5 and sheath 6; five-strand round coil 1 and four PE wires The wire 2 is wrapped by an aluminum foil 4, the aluminum foil 4 is provided with a braided layer 5, the external ground wire 3 is buried between the aluminum foil 4 and the braided layer 5, and the outer layer of the braided layer 5 is provided with a sheath 6. Wherein, each strand of coil 1 includes a pair of signal wires 11 wrapped with aluminum foil 13 and a built-in ground wire 12 .

[0027] The specific manufacturing process of the above-mentioned high-definition multimedia connection line is as follows:

[0028] a. Production of foaming wire: The bare copper wire of the inner conductor is extruded on a layer of foaming PE material through a 50-type extruder, and there are two kinds of white and blue.

[0029] b. Production of PE core wire...

Embodiment 2

[0037] The difference between the second embodiment and the first embodiment is that the five-strand coil 1 and the four PE wires 2 are first covered with a layer of PET film, and then covered with aluminum foil 4 .

Embodiment 3

[0039] The difference between Embodiment 3 and Embodiment 1 is that in Embodiment 1, the diameters of the signal wire 11, the four PE wires 2 and the built-in ground wire 12 are the same; while the diameters of the four PE wires 2 and the built-in ground wire 12 used in Embodiment 3 are It is assumed that the diameter of the ground wire 12 is smaller than the diameter of the signal wire 11 . For example, the signal line 11 uses No. 24 wire (0.511mm in diameter), while the four PE wires 2 and the built-in ground wire 12 use No. 26 (0.404mm in diameter), No. 28 (0.32mm in diameter) or No. 30 wire (0.254mm in diameter). mm).

Abstract

The invention relates to a HDMI connecting line and a manufacturing method thereof. The HDMI connecting line comprises five strand coils, four PE wires, one peripheral ground wire, an aluminum foil, a braiding layer and a sheath. The five strand coils and the four PE wires are wrapped by the aluminum foil. The braiding layer is arranged out of the aluminum foil. The peripheral ground wire is buried between the aluminum foil and the braiding layer. The sheath is arranged on an external layer of the braiding layer. The each strand coil comprises a pair of signal lines wrapped by a wing aluminum foil and one internal ground wire. According to the invention, a fundamental change is made to the current HDMI connecting line. A transmission capability of the signal line is enhanced. The number of electronic line is reduced. Signal transmission quality is further improved. Simultaneously, normal working of the electronic line can be maintained. On an appearance aspect, an external diameter size of a whole cable can be reduced. A usage amount of a material except the cable can be reduced. An esthetic effect of the cable is increased. Production cost is reduced and resources can be saved.

Description

technical field [0001] The invention relates to a multimedia connection line and a manufacturing method of the multimedia connection line. Background technique [0002] High-definition multimedia cable (referred to as HDMI cable) is mainly used to transmit high-definition digital signals between DVD, PS3, high-definition digital TV set-top boxes and high-definition digital TV, 3D TV or display devices. HDMI cables can transmit audio and video signals at the same time. The HDMI cable transmits a large amount of traffic, and all information is transmitted in the form of digital signals. In this way, the signal will not be distorted during transmission. Since the HDMI cable can integrate audio and video signal transmission, and is small in size, light in weight, and beautiful in appearance, it will gradually replace the existing audio and video signals and VGA cables and be widely used. [0003] For the structure of the existing HDMI cable, please refer to figure 1 , which ...
