Problems solved by technology

[0002] At present, most of the audio and video monitoring cables used in locomotives are only simple audio or video cables, and they are two separate cables, and none of the cables has dual functions.
At the same time, the audio and video data transmission signals of this cable are poor, which cannot meet the requirements of use.
These cables have no shielding function, poor flexibility, no torsion resistance, low strength, no tensile resistance, inconvenient to use, and short service life

Embodiment Construction

[0020] The present invention will be further explained below in conjunction with the accompanying drawings.

[0021] As shown in the accompanying drawings, it is the audio and video monitoring cable for locomotives of the present invention. The locomotive audio and video monitoring cable includes an outer sheath 1, a total shielding layer 2, a drain wire 3, a wrapping tape 4, a video control wire 5, a filling material 6, a voice control wire 7 and a power control wire 8.

[0022] The wrapping tape 4 wraps the video control line 5, the voice control line 7 and the power control line 8 into a circle; the filling material 6 is filled in the gap between the video control line 5, the voice control line 7 and the power control line 8; A total shielding layer 2 and an outer sheath 1 are wrapped in turn around the wrapping tape 4 ; the drain line 3 is arranged between the wrapping tape 4 and the total shielding layer 2 .

[0023] The video control line 5 is composed of an inner condu...

Abstract

The invention discloses a locomotive audio-video monitoring cable which comprises a video control wire, a voice control wire and a power supply control wire, wherein, the video control wire, the voice control wire and the power supply control wire are wound by a winding belt to form a circle, a whole shielding layer and an outer sheath are sequentially covered outside the winding belt, and a drainage lead is arranged between the winding belt and the whole shielding layer. The locomotive audio-video monitoring cable is especially suitable for the transmission and the monitoring of voice-frequency and video digital signals inside the locomotive. The main technology of the product adopts a novel material and a new structure, thus having the advantages of multiple functions, good shielding property, tensile strength, torsional strength and durable performance, etc.

Description

technical field [0001] The invention relates to an audio and video monitoring cable, in particular to an audio and video monitoring cable for a locomotive. Background technique [0002] At present, most of the audio and video monitoring cables used by locomotives are simple audio or video cables, and are two separate cables, and none of the cables has dual functions. At the same time, the audio and video data transmission signals of this cable are poor, which cannot meet the requirements of use. These cables have no shielding function, poor flexibility, no torsion resistance, low strength, no tensile resistance, inconvenient use, and short service life. Contents of the invention [0003] Purpose of the invention: Aiming at the above-mentioned deficiencies in the prior art, the present invention provides an audio and video monitoring cable to realize that a cable has the characteristics of multi-function, good shielding performance, tensile resistance, torsion resistance a...
