Abstract

本发明公开的电线由能够传导电流的金属线构成，其外表面包裹在由特定的金属按设定量组成的合金中。

Description

电导体
发明领域
本发明涉及电线领域。
背景技术
小的和可变的电信号例如声频信号的传输已经证明是一种比本领域已经知道的要复杂得多的现象，这是因为在电信号的传输中，发生了听众可听见的现象，如声音的音色、空间性和刺耳度，虽然这些现象不能用仪器来鉴别。
由用来制造传统电线的铜造成的高频的失真和中声频的压缩(packing)是可听见的并且立即被银布线(silver wiring)察觉。
为了克服上述问题，美国专利6399885公开了由许多电线组成的电缆，这些电线按串联或并联的方式排放，各自由不同的金属(具体是金、铜、或银)制造，所述的电线彼此绝缘并被包裹在介电护皮中。
尽管这些电线很可靠，但由于需要用金并且制造复杂，它们显然难以按工业水平来提供。
另一种解决办法是应用滤波器或补偿电路，以便补偿由部件的金属和布线产生的各种音色或失真。但是，其结果不完全令人满意，失真仍然存在，无法消除并能被听众察觉。
鉴于单独使用银可产生非常清晰的无失真的声音，但这种声音很弱并且确实太金属性的事实，因此，消除上述的与纯金属相关的负面因素就非常重要。
发明内容
令人惊喜地发现，有可能以完全令人满意的方法解决上述问题，所述的方法是使用金属线，在它的表面上沉积由合适的金属按设定的百分比组成的合金。
另外，已经发现，本说明书所叙述的和所主张保护的电线不仅完美地解决了上述的问题，而且还可用于其它的应用，在这些应用中电信号传输的纯度对于获得优秀的最终性能是必需的。
具体实施方式
本发明的电线由能够传导电流的普通金属构成，例如铜线，其外表面覆盖在含锡、锑和铜的合金之中。
优选地，构成该合金的各种金属以下列浓度存在：
锡                      74％-98.9％
锑                      1％-10％
铜                      0.1％-25％
更优选地，本发明合金由锡95％、锑4％、铜1％构成。
通常，随着合金层厚度增加，电线的品质也提高。
为了得到本发明电线，将金属线浸渍在包含熔融合金的池(浴)中。显然，电线停留在池中的时间取决于池的温度、构成电线的金属的种类和电线的尺寸，以便使合金沉积在电线上而不会由于在过高的温度浸泡的时间太长而使电线发生熔化或损坏。
如果，例如，电线的直径是0.4mm，使用的池有300℃-450℃之间的温度，则电线浸泡的时间是大约三秒钟。
在浸渍入熔融的合金池之前，金属线最好先通过一种焊剂，其种类为通常用于电气材料的焊接或用于电路制造的种类，例如松香，然后让它干燥，该焊剂能提高熔融合金对电线的粘合性。
如果需要，在浸渍入合金浴之前，可以将电线预热到，例如60°-90℃之间的温度。
以下是制造本发明电线的实施例。
实施例1
将直径为0.40mm的铜线通过松香，让它干燥，然后将该铜线预热到60°-80℃。
然后将该电线以3m/min的速度浸渍入装有熔融的由锡(95％)、锑(4％)和铜(1％)构成的合金的坩埚中，其温度为大约400℃，浸泡时间为大约3秒钟。
然后将沉积了一层合金的电线冷却。
实施例2
重复实施例1，使用0.90mm电线，并以大约3.3cm/sec的速度将其浸渍，保持合金池的温度在大约400℃。
用按照以上实施例制造的电线进行的试验表明，分辨率(resolution)有了相当大的提高，因为在例如声频或视频领域中，与其有关的参数都提高了：环境、微观对比度和颜色。
本发明电线适合于非常宽广范围的应用，不仅可作为低水平信号用的接线电缆，而且可用作电力供应接线电缆，用于印刷电路轨道，用于耦合、信号、脉冲和电力变压器，用于偶极、阵列和微波传送带天线，用于供信号或电力供应用的连接线以及用于电磁屏蔽的连接器。
本发明特别涉及电力变压器，用于模拟、数字和脉冲信号的配电网和/或耦合变压器，它们的线圈是用上述的电线制造的。
优选地，用于本发明变压器的介电护皮是用黑丝(black silk)制造的，优选编织在电线本身上面。
特别是，所述的变压器能够提高声频信号中的动力学，降低供电噪声；它们还能够提高微信息和环境，改变录制和重放(复制)系统的音色；所述的现象也能够在耦合变压器中获得。
将所述电力变压器用于视频系统，可提高颜色和对比度，降低噪声。
用上述的电线制造的用于数字信号的变压器与用其它电线材料制造的变压器比较，对于上述参数已经产生了非常好的结果。
