本申请要求在2016年3月30日提交中国专利局、申请号为201620256105.8、名称为“柔性扁平电缆”的中国专利申请的优先权，该申请的全部内容通过引用结合在本申请中。
技术领域
本申请实施例属于电子电路技术领域，例如涉及一种柔性扁平电缆。

具体实施方式
下面结合附图和实施例对本申请作详细地说明。可以理解的是，此处所描述的实施例仅仅用于解释本申请，而非对本申请的限定。另外还需要说明的是，为了便于描述，附图中仅示出了与本申请相关的部分而非全部结构。在不冲突的情况下，本申请实施例中的特征可以任意组合。
第一实施例
本实施例提供了柔性扁平电缆的第一种技术方案。在该技术方案中，所述柔性扁平电缆中的电源传输导体的横截面宽度大于信号传输导体的横截面宽度。
参见图1，所述柔性扁平电缆包括：绝缘膜11，以及被夹持在所述绝缘膜11中的传输导体12。
所述绝缘膜11是由绝缘材料制成的柔性膜。所述绝缘膜11覆盖在所述导体11的两侧，能够保证所述柔性扁平电缆中不同传输导体12之间相互绝缘，同时可以保证所述传输导体12与外界绝缘。
所述绝缘膜可以是由聚对苯二甲酸乙二醇酯(Polyethylene terephthalate，PET)材料制成的。而且，在本实施例的一些可选实施方式中，所述绝缘膜可以不仅仅是一个单层膜，而是由不同材料制成的，具有多个材料层的复合膜。所述复合膜可以包括基膜层、阻燃层等多个材料层。
所述传输导体12由金属材料制成。可选的，所述传输导体12为其上表面镀有锡层的铜线。由于所述传输导体12具有较好的电导率，其能够完成各种电信号的传输。
所述传输导体12包括：电源传输导体121及信号传输导体122。可选的，所述传输导体的总数是二十个，其中，所述电源传输导体121的个数是三个，而所述信号传输导体122的个数是十七个。参见图1，上述三个电源传输导体121设置在上述十七个信号传输导体122的一侧，并且任意两个电源传输导体121之间不会再设置其他的信号传输导体122。
图2示出了本实施例提供的柔性扁平电缆的A-A’剖面图。参见图2，无论所述电源传输导体121，还是所述信号传输导体122，其横截面的形状均为矩形。在本实施例中，所述电源传输导体121的横截面宽度大于所述信号传输导体122的横截面宽度。同时，所述电源传输导体121的横截面厚度与所述信号传输导 体122的横截面厚度相同。由于上述宽度及厚度设置，所述电源传输导体121的横截面面积大于所述信号传输导体122的横截面面积。而且，所述电源传输导体121的横截面面积相较于所述信号传输导体122的横截面面积，要大20％至30％。
由于每个传输导体的分布电阻可以由如下公式给出：
Figure PCTCN2016097023-appb-000001
其中，R表示所述传输导体的分布电阻，ρ表示所述传输导体的电阻率，L表示所述传输导体的长度，而S表示所述传输导体的横截面面积。
可以理解的是，一旦所述传输导体的材料选定，其电阻率一般是一个定值。因此，增大所述传输导体的横截面面积，则单位长度的传输导体的分布电阻的阻值就会下降。由于所述传输导体的分布电阻阻值的下降，由传输造成的能量耗散就会降低，从而使得所述传输导体两端的电压压降降低。
由于所述电源传输导体的横截面面积大于所述信号传输导体的横截面面积，所述电源传输导体的分布电阻的阻值会小于所述信号传输导体的分布电阻的阻值。由于其上的分布电阻的阻值较小，因此，采用所述电源传输导体进行传输时，产生的电压压降也就相对较小。
本实施例通过增大传输导体中电源传输导体的宽度，增大了所述电源传输导体的横截面面积，降低了所述电源传输导体的分布电阻阻值，有效的降低了采用电源传输导体进行传输时产生的电压压降。
第二实施例
本实施例提供了柔性扁平电缆的第二种技术方案。在该技术方案中，所述柔性扁平电缆中的电源传输导体的横截面厚度大于其中的信号传输导体的横截面厚度。
参见图3，所述柔性扁平电缆包括：绝缘膜31，以及被夹持在所述绝缘膜31中的传输导体32。图4是本申请第二实施例提供的柔性扁平电缆的B-B’剖面图。
所述绝缘膜31的结构及功能与本申请第一实施例中提供的绝缘膜完全相同，在此不再赘述。
所述传输导体32由金属材料制成。所述传输导体32可以由表面涂覆有锡层的铜线制成。采用上述材料制成的传输导体32具有较好的电导率，因此可以进行电信号的传输。
与本申请第一实施例相同，所述传输导体也包括：电源传输导体321及信号传输导体322。所述电源传输导体321的数目可以是三个，所述信号传输导体322的数目可以是十七个。而且，所述电源传输导体321均设置在所述信号传输导体322的一侧。并且，任意两个电源传输导体321中间不会孤立的设置一个信号传输导体322。任意两个信号传输导体322中间也不会孤立的设置一个电源传输导体321。
与本申请第一实施例的不同之处在于，在本实施例中，所述电源传输导体321的横截面宽度与所述信号传输导体322的横截面宽度相等，转而依靠横截面厚度的增加而增大所述电源传输导体的横截面面积。也就是说，所述电源传输导体321的厚度大于所述信号传输导体322的厚度。
由于所述电源传输导体321的横截面厚度大于所述信号传输导体322的横截面厚度，所述电源传输导体321的横截面面积大于所述信号传输导体322的横截面面积。基于与本申请第一实施例中相类似的原因，所述电源传输导体321的分布电阻小于所述信号传输导体322的分布电阻，从而使得所属电源传输导体的传输压降降低。
本实施例通过增大传输导体中电源传输导体的厚度，增大了所述电源传输导体的横截面面积，降低了所述电源传输导体的分布电阻阻值，有效的降低了采用电源传输导体进行传输时产生的电压压降。
第三实施例
本实施例提供了柔性扁平电缆的第三种技术方案。在该技术方案中，不仅所述柔性扁平电缆中的电源传输导体的横截面宽度大于信号传输导体的横截面宽度，而且所述柔性扁平电缆中的电源传输导体的横截面厚度大于信号传输导体的横截面厚度。
参见图5，所述柔性扁平电缆包括：绝缘膜51，以及被夹持在所述绝缘膜51中的传输导体52。图6是本申请第三实施例提供的柔性扁平电缆的C-C’剖面图。
所述绝缘膜51的结构及功能与本申请第一实施例中提供的绝缘膜完全相同。
所述传输导体52的结构布置与本申请前述实施例相类似。与本申请前述实施例不同的是，本实施例中的电源传输导体521的横截面宽度及横截面厚度均大于信号传输导体522。由于横截面宽度及横截面厚度均大于所述信号传输导体522的相应参数，所述电源传输导体521的横截面面积也大于所述信号传输导体522的横截面面积。基于与本申请前述实施例中相类似的原因，所述电源传输导体521的分布电阻小于所述信号传输导体522的分布电阻，从而使得所属电源传输导体的传输压降降低。
本实施例通过增大传输导体中电源传输导体的横截面宽度及横截面厚度，增大了所述电源传输导体的横截面面积，降低了所述电源传输导体的分布电阻阻值，有效的降低了采用电源传输导体进行传输时产生的电压压降。
以上所述仅为本申请的可选实施例，并不用于限制本申请，对于本领域技术人员而言，本申请可以有各种改动和变化。
工业实用性
本申请实施例提供的柔性扁平电缆，有效的降低了采用电源传输导体进行传输时产生的电压压降。
