磁环对HDMI线的重要性,不可省略

date:On December 08, 2017 Source:  

   HDMI线的抗干扰能力就是磁环所带来的效果,为什么HDMI线这么受欢迎,完全是经过多种技术的保护与加工而制成的,如何一条细小的线材,却能带来这么大的效果,高清输出的经过完全是取决的线材的稳定性,有时候看视频为什么会卡,主要是传输不够稳定,带宽跟不上,所以HDMI线的出现就起到很好的作用,在这当中磁环就起到一个抗干扰能力,所以在HDMI线的加工上就选用上了磁环,那么磁环到底有什么特别的地方呢,下面马上进行分享。

HDMI cable anti-jamming capability is the effect of the magnetic ring, why HDMI cable is so popular, is completely protected by a variety of technologies and processing made, how a small wire, it can bring such a big Effect, high-definition output is completely dependent on the stability of the wire, and sometimes look at why the video card, the main transmission is not stable enough, the bandwidth can not keep up, so the emergence of HDMI cable to play a very good role in this Magnetic ring to play an anti-interference ability, so the HDMI cable processing on the choice of a magnetic ring, then the magnetic ring in the end what is the special place, the following immediately share.

HDMI线

   磁环它是电子电路中常用的抗干扰元件,对于高频噪声有很好的抑制作用,一般使用铁氧体材料(Mn-Zn)制成。磁环在不同的频率下有不同的阻抗特性,一般在低频时阻抗很小,当信号频率升高磁环表现的阻抗急剧升高。大家都知道,信号频率越高,越容易辐射出去(要买优质的电脑机箱也是要减小电磁泄漏),而一般的信号线都是没有屏蔽层的,那么这些信号线就成了很好的天线,接收周围环境中各种杂乱的高频信号,而这些信号叠加在本来传输的信号上,甚至会改变原来传输的有用信号。那么在磁环作用下,使正常有用的信号很好的通过,又能很好的抑制高频干扰信号的通过,而且成本低廉。

Magnetic ring It is commonly used in electronic circuits anti-jamming components, for high-frequency noise has a good inhibitory effect, the general use of ferrite materials (manganese - zinc) made. The magnetic ring has different impedance characteristics at different frequencies, and the impedance is generally small at low frequency. When the signal frequency increases, the impedance of the magnetic ring increases sharply. As we all know, the higher the signal frequency, the easier it is to radiate (to buy a good computer chassis is to reduce electromagnetic leakage), and the general signal lines are not shielded, then these signal lines have become very good antenna , To receive the clutter of the surrounding high-frequency signals, and these signals superimposed on the original signal transmission, and even change the original useful signal transmission. So under the action of the magnetic ring, the normal and useful signals pass well, and the signals of high frequency interference can be well suppressed, and the cost is low.


   不同的磁材会有不同的磁导率、不同的温度特性。其中温度特性是最重要的,因为一支节能灯在工作中,磁环必须经历常温、高温(高达100℃)、低温,然后在高温当中恒定工作。但是,不同材料的温度曲线会有很大的差别,磁导率低的会在前半端呈现得比较平坦,磁导率较高的会显得比较陡峭;不同的温度里,饱和磁感应强度BS的变化也会不同,所以HDMI线选用的是较好磁材作为加工的一部分,为传输与干扰的能上增加了不同的重要性质,所以今天你了解了HDMI线就能了解磁环的一部分了解,更多传输方案就深圳利诺威。

Different magnetic materials will have different magnetic permeability, different temperature characteristics. Among them the temperature characteristic is the most important, because a energy-saving lamp in the work, the magnetic ring must go through the normal temperature, the high temperature (up to 100 ℃), the low temperature, and then the constant work under the high temperature However, the different material temperature curve may have the very big Difference, low permeability will appear in the first half of the relatively flat, higher permeability will appear steeper; different temperatures, the saturation magnetic flux density of the BS changes will be different, so the choice of HDMI cable is better As part of the processing of magnetic materials for the transmission and interference can increase the different important properties, so today you understand the HDMI cable can understand some of the understanding of the magnetic ring, more transmission solutions on the Shenzhen Linuo Wei.
