Embodiment Construction

[0017] The present invention will be further explained below in conjunction with the accompanying drawings.

[0018] As shown in the accompanying drawings, it is the video data cable for locomotives of the present invention. The locomotive video data cable includes a voice control cable 7 , a power control cable 4 and a power control cable 5 .

[0019] 1 voice control cable 7, 2 power control cables 4 and 6 power control cables 5 are wound into a circle by the wrapping tape 3, and the overall shielding layer 2 and the outer sheath are sequentially wrapped outside the wrapping tape 3 1; Between the wrapping tape 3 and the overall shielding layer 2, there is a drain wire 6 made of a tinned stranded wire.

[0020] The voice control cable 7 is composed of four inner conductor groups 9 wrapped around the wrapping tape 10, and a shielding layer 8 and an inner sheath 14 are arranged in sequence on the outer periphery of the wrapping tape 10; the inner conductor groups 9 are two wrap...

Abstract

The invention discloses a compound audio-frequency control cable for locomotives, comprising a voice control cable and two power supply control cables which are wound into a round shape by a winding belt, and a whole shielding layer and an outer sheath are sequentially wrapped outside the winding belt, and a drainage lead is arranged between the winding belt and the whole shielding layer. The compound audio-frequency control cable is particularly suitable for the transmission and signal control of the audio-frequency digital signal inside the locomotives. The main technology of the compound audio-frequency control cable adopts a novel material and a novel structure and overcomes the disadvantages of prior cable such as easy to break, no tension, no torsional strength and single function, and the strength of the whole cable is improved and the using function of the cable is increased. The compound audio-frequency control cable has the advantages of multiple functions, good shielding performance, tensile strength, torsional strength and durable performance, etc.

Description

technical field [0001] The invention relates to a composite audio control cable, in particular to a composite audio control cable for locomotives. Background technique [0002] At present, the audio control cables used in locomotives are mostly single-core wires, and the audio data transmission signal is poor, which cannot meet the requirements of use. At the same time, 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 a composite audio control cable for locomotives to realize the characteristics of multi-functional cables, good shielding performance, tensile resistance, torsion resistance and durability. [0004] Technical solution: In order to realize the above-mentioned purpose of the invention, the technical ...
