技术领域technical field
本发明涉及屏蔽铜箔及其应用技术领域，尤其是指一种屏蔽复合铜箔及使用该铜箔的对绞数据传输线。The invention relates to the technical field of shielding copper foil and its application, in particular to a shielding composite copper foil and a twisted pair data transmission line using the copper foil.
背景技术Background technique
屏蔽铜箔主要是用于屏蔽信号线电信号或磁信号，屏蔽主要是依靠铜本身优异的导电性能，主要用于消除电磁干扰；目前的数据线用铜箔缠绕(绕包)的屏蔽线缆广泛应用于电子信号传输、控制、航空、医疗器械等领域，一般通过铜箔缠绕的线缆的情况下能起到良好的屏蔽效果，然而，在某些对绞数据传输线(雷电线)的加速寿命测试中，当到达一定的温度条件下，线缆传输信号衰减严重；对其进行研究发现观察发现，由于铜箔本身较薄，在缠绕弯折或高温下容易变形，而且复位能力较差，对绞的芯线易产生相对位移，因此导致屏蔽性能受到影响，尤其是在屏蔽效果要求高的场合体现的更加明显，极易引起衰减的异常波动。Shielding copper foil is mainly used to shield signal line electrical signals or magnetic signals. Shielding mainly relies on the excellent electrical conductivity of copper itself, and is mainly used to eliminate electromagnetic interference; current data lines are shielded cables wrapped (wrapped) with copper foil It is widely used in electronic signal transmission, control, aviation, medical equipment and other fields. Generally, it can play a good shielding effect in the case of cables wound with copper foil. However, in the acceleration of some twisted data transmission lines (lightning wires) In the life test, when the temperature reaches a certain level, the cable transmission signal attenuates seriously; it is found that due to the thin copper foil itself, it is easy to deform when it is wound or bent at high temperature, and the reset ability is poor. The twisted core wires are prone to relative displacement, which will affect the shielding performance, especially in the occasions where the shielding effect is high, and it is easy to cause abnormal fluctuations in attenuation.
