Description
本发明涉及一种内装光波导管的带状光缆，这种带状光缆中至少并行排列有两条光波导管，光波导管嵌装在带状载体内，相互间有间隔隔开（见EP-PSO 091717）。
光波导管-下文中缩略为LWL-是由玻璃纤维制成的成品件，无需再做加工即可用来传输光波。这种光波导管在通信技术方面可以用来取代以前通用的金属导体。同金属导体相比，光波导管有很多优点：光波导管的频带宽、衰耗小，易弯曲，直径小，此外不易受外界电磁干扰场的影响。
如将光波导管用于通信技术中的传输目的，则可将光波导管装在光缆（光波导管电缆）中，光波导管在光缆中受到保护，不易受到机械损坏。在光缆中，光波导管既可作为单个的机体，也可将多根光波导管组合在一起装入光缆芯中。
在将光波导管加工成光缆之前，先将光波导管组装在一起的方法之一如一开始所提到的EP-PSO 091717专利所述。使用这种方法，先将光波导管组装成带状导线的形状，带状导线由一带状的载体组成，载体中并行排列有若干通道。光波导管松散地位于通道中，光波导管是在载体制成后插入的。一条外面包有保护层的光缆芯中至少装有一条这样的带状光缆。这样，总的来看，这种制造方法费用高、工序多。尤其是制造带状光缆本身更是这样，因为首先必须制造出带有通道的载体，然后再费时耗资地将光波导管插入载体通道中。
本发明的任务是，研制出一种带状导线形式的光缆，这种光缆制造简单，不需采取其它保护措施即可作为制成品使用。
根据本发明，以本文开头所说的这种带状光缆解决这一任务的方法是，将光波导管嵌装于两个各有一面涂有粘胶层的扁带中，两条扁带既能粘住光波导管，又能互相粘合，而且，扁带的热膨胀系数又和光波导管的热膨胀系数相等。
通过将光波导管嵌装在两条扁带之间，光波导管的整个长度均牢牢固定在扁带中，此外，防潮和抗弯曲或抗扭折损伤的性能也好。由两条扁带夹合光波导管所形成的结合体使这种带状光缆具有必需的机械稳定性。这种机械稳定性在带状光缆所处的各种条件下均可保持不变。尤其是在温度的影响下更是这样：由于制造扁带所用材料的热膨胀系数与光波导管的热膨胀系数相同，故温度不会对光缆的机械稳定性产生不利影响。就是说，在光波导管和扁带之间不会由于温度变化而发生相对运动。
装有光波导管的这种扁形带状光缆机械性能非常好，无需附加保护即可用作光缆或光波导线。因此，这种光缆比如可以用作安装用普通导线，可以敷设于糊墙纸底下，装于墙上，或铺设在室内地板上的地毯下面。安装时可以将带状光缆用相应的线架粘贴，或根据相应的形状用不带光波导管的板条加钉子钉住带状光缆的边缘或中间。带状光缆亦适宜于穿进建筑物墙壁中敷设的管道内。
在带状光缆中至少装两条光波导管，最好装入数量较多的光波导管，光波导管相互间以固定的距离隔开。这样，它们很容易同时连续连接，或接到仪器上，尤其是当光波导管在一预先准备好的网栅里相互并行排列时就更便于连接。
本发明的一种结构实例在附图中绘出。
其中：
图1和图2是按本发明制造的带状光缆不同结构的截面图。
图3是一条带状光缆的顶视图。
在图1至3所绘的带状光缆1中，扁带3和4之间嵌装有6根光波导管2，两条扁带各有一个面涂有可粘合的涂层。扁带3和4的粘合层在制造带状光缆1时相向而对，以便在将光波导管2装入时使光波导管之间的间隙和扁带的边缘相互粘合。带状光缆1中装入的光波导管数目任意。光波导管数可视不同的使用目的而定。在最佳结构形式中，一根带状光缆1中比如可以并排安装5至10根光波导管2。
组装在带状光缆1中的光波导管2可用相应的连接元件或焊接器同时全部连接或焊接。尤其是当带状光缆1中的光波导管2以带状光缆的全部宽度置于一个预先备好的网栅中时就更便于连接。
扁带3和4的材料温度膨胀系数相当于光波导管2的温度膨胀系数。这样可以做到温度变化对光波导管2无影响。在最佳结构形式中，扁带3和4的材料可以使用任意一种玻璃纤维增强的塑料。在带状光缆1中，光波导管2的嵌装在机械方面受到保护。此外，尤其在使用玻璃纤维增强的塑料带时，带状光缆1抗拉性能强。将光波导管2嵌装于扁带3和4之间，总的来说它们构成了一个易于弯曲的组合体，在这个组合体中，在机械方面易受损坏的光波导管2即便在弯曲时也可保持足够的稳定。
带状光缆的制造情况举例如下：
将所需要的光波导管2数目从线架上取下，然后相互并行送到一个压紧装置上，压紧装置比如由两个可旋转的轴承辊构成。光波导管2与扁带3和4位于光波导管2的不同侧面，二者各有一个面有粘合层，在制造带状光缆1时，两个粘合层同时对着光波导管2。
利用两轧辊将扁带3和4压到光波导管2上，这时扁带3和4与光波导管2粘合在一起，光波导管2相互间有间隔地粘在一起，同时，两条扁带的边缘也粘合在一起。如果为压制而使用定做的压辊，则带状光缆1的截面就呈现图2中的样子。这时扁带3和4也挤压进光波导管的间隔之中。
