Abstract
The utility model relates to an audio and video signal transmission cable. The audio and video signal transmission cable includes a cable core, and a weaving belt and an external sheath which are wrapped outside the cable core in sequence, wherein the cable core includes a digital audio signal transmission line, an analogue audio signal transmission line, and a video signal transmission line which are integrally stranded, and polyester belt filler is wrapped outside the cable core in a pressing manner. In the audio and video signal transmission cable, the digital audio signal transmission line, the analogue audio signal transmission line, and the video signal transmission line are integrally stranded, so that the three signal lines can be paved at the same time, thereby reducing construction cost and improving construction efficiency. In addition, the strength of the integrally stranded cable is improved distinctly, so that the audio and video signal transmission cable can be applied to a wide range.
Description
Technical field
The utility model relates to a kind of signal-transmitting cable, particularly a kind of transmission cable for transmission of digital, simulation, video, audio signal.
Background technology
Signal-transmitting cable of the prior art, video, audio frequency and digital signal transmission cable generally separately lay, three kinds of cables all need to be applied to respectively family, take up room large, trouble is installed, construction cost improves, and mutual interference is larger, and the cable intensity difference laying separately, fragile or break, in the environment for use of many complexity, be subject to restrictedly, seriously restricted the use occasion of signal-transmitting cable.
Utility model content
The problem that the utility model exists for prior art, a kind of applied widely, transmission cable of transmission of digital, simulation, video and audio signal is simultaneously provided, simplifying signal-transmitting cable laying work, reduce construction cost, the phase mutual interference while reducing signal transmission.
The purpose of this utility model is to realize like this, a kind of audio frequency, video signal transmission cable, comprise outer wrapped braiding band and the oversheath successively of core and core, described core comprises whole stranded digital audio and video signals transmission line, simulated audio signal transmission line and video signal transmission wire, and described core extrudes polyester belt filler outward.
Adopt signal-transmitting cable of the present utility model, digital audio and video signals transmission line, simulated audio signal transmission line and video signal transmission wire integral body are twisted into one, can realize three kinds of holding wires has once laid, reduce construction cost, improve efficiency of construction, and the cable intensity after integral body is stranded obviously improves, and applicable situation is wide.
For further improving the signal transmission performance of cable, reduce the phase mutual interference between signal, described digital audio and video signals transmission line and video signal transmission wire arrange respectively two strands, and along core, be right-angled intersection diagonal angle and distribute, described simulated audio signal transmission line is arranged with six strands and digital audio and video signals transmission line and video signal transmission wire are isolated respectively along core.Signal-transmitting cable of the present utility model, is symmetrical arranged each transmission signal line and be spaced from each other along core, and the phase mutual interference that can cancel out each other between each signal transmission improves signal transmission performance.
Accompanying drawing explanation
Fig. 1 is a kind of audio frequency of the present utility model, video signal transmission construction of cable schematic diagram.
Wherein, 101 digital audio and video signals transmission lines; 102 simulated audio signal transmission lines; 103 video signal transmission wire; 2 braiding bands; 3 oversheaths; 4 polyester belt fillers.
Embodiment
Be illustrated in figure 1 audio frequency of the present utility model, video signal transmission cable, comprise outer wrapped braiding band 2 and the oversheath 3 successively of core and core, core comprises whole stranded digital audio and video signals transmission line 101, simulated audio signal transmission line 102 and video signal transmission wire 103, and core extrudes polyester belt filler 4 outward; Digital audio and video signals transmission line 101 and video signal transmission wire 103 arrange respectively two strands, and along core, be right-angled intersection diagonal angle and distribute, simulated audio signal transmission line 102 is arranged with six strands and digital audio and video signals transmission line 101 and video signal transmission wire 103 are isolated respectively along core.In the present embodiment, it is φ 3.3 that simulated audio signal transmission line 102 adopts external diameter, wire size is the cable of L-2B2AT or L-2SCHD, it is φ 4.1 that digital audio and video signals transmission line 101 adopts external diameter, wire size is the cable of DA202AT, and it is φ 4.3 that video signal transmission wire 103 adopts external diameter, and wire size is L-2.5CHD cable, whole external diameter stranded and that fill the cable after extruding is φ 17.6mm, and oversheath thickness is 1.5mm.Signal-transmitting cable of the present utility model, by digital audio and video signals transmission line 101, simulated audio signal transmission line 102 and video signal transmission wire 103 integral body are twisted into one, and each transmission signal line is symmetrical arranged and is spaced from each other along core, the phase mutual interference that can cancel out each other between each signal transmission, make the interference of each signal transmission as far as possible little, realizing three kinds of holding wires has once laid, reduce construction cost, improve efficiency of construction, and the cable intensity after integral body is stranded obviously improves, wide model is applicable to various military, civilian, numeral, simulation, in the transmission of video and audio signal.
The utility model is not limited to above-described embodiment; for example each transmission news road is not limited to the quantity in embodiment; every on the basis of the disclosed technical scheme of the utility model; those skilled in the art is according to disclosed technology contents; do not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein, these replacements and distortion are all in the scope of the utility model protection.
