Problems solved by technology

[0008] Since each signal line is used in conjunction with a lotus plug and the corresponding socket, the connection between the audio and video lines of the TV set and the external circuit is cumbersome, which brings a lot of difficulties to the appearance design; and the lotus plug and the socket occupy a large The volume is not conducive to the planar design of the TV; at the same time, it is extremely inconvenient for users to plug in and out, and it is easy to plug in by mistake

Embodiment Construction

[0021] Such as figure 1 As shown, the audio and video signal line of the present invention includes: a signal line body with 19 cores, its two ends have plug terminals J1 and J2 respectively, and the plug terminals J1 and J2 are mated with sockets J1-1 and J2-1 .

[0022] Among them, the sockets J1-1 and J2-1 adopt current common materials to facilitate users or reduce costs.

[0023] Of course, the plug terminals J1 and J2 both have 19 core wires, and each core wire is consistent with the core wires in the signal cable body.

[0024] In the 19-core signal cable body, the core wires used to transmit different signals are distinguished by different colors for the convenience of users.

[0025] As shown in Table 1, the 19 core wires in the signal cable body are: the first core wire is VGA-R signal wire, the second core wire is ground wire, the third core wire is VGA-G signal wire, and the fourth core wire is VGA-R signal wire. 5VGA-B signal line, the 6th core is the ground, t...

Abstract

The invention discloses a connecting line for digital audio-video signals, comprising a connecting line body of a 19 core line, which integrates a color difference video input signal line Y/Pb/Pr, a vertical synchronous signal line VSY, a horizontal synchronous signal line HSY, a VGB signal line and an audio line. A plug terminal is respectively arranged at both ends of the connecting line body, and is butted with a socket in a matching way. A prior high-definition digital television signal line is integrated to an audio-video signal line to be uniformly managed, and plugs and sockets of various signal lines are reduced, thereby the invention is convenient to use for users, is beneficial to planarization design of the television, and has wider use prospect.

Description

technical field [0001] The invention relates to a signal transmission line structure, in particular to a connection line for transmitting audio and video signals. Background technique [0002] With the continuous emergence of high-definition panel TVs, digital multimedia technology is also changing and developing vigorously, and digital TV technologies such as IPV6 and IPTV have emerged. But the TV still relies on the traditional audio and video cable to acquire the digital TV signal externally. [0003] At present, the signal lines for digital TV and external signal transmission generally include: [0004] 1. Component video input signal lines: Y, Pb, Pr; [0005] 2. Vertical synchronization signal line: VSY, horizontal synchronization signal line: HSY; [0006] 3. VGB signal line: red primary color signal line R, green signal line G, blue primary color signal line B; [0007] 4. Audio cable: left channel line L, right channel line R. [0008] Since each signal line is...
