具体实施方式
下面将结合本发明的附图，对本发明实施例的技术方案进行清楚、完整的描述。
本发明所揭示的一种光电混合金属丝铠装缆，采用金属丝梳绕铠装，主要改善了现有波纹铠装混合缆的弯曲性能和加工生产工艺。
结合图3～图5所示，本发明所揭示的一种光电混合金属丝铠装缆，包括光电混合单元、金属丝铠装100和外护套200，金属丝铠装100包裹在光电混合单元外，外护套200包裹在金属丝铠装100外。
具体地，光电混合单元包括混合的电源单元和光单元101，其中，电源单元包括至少两根电通信链路，每根电通信链路包括多根金属丝绞合的 电源导体102和包裹在电源导体102外的绝缘材料103，绝缘材料103的横截面为圆形或扇形。光单元101包括一对或多对光纤芯。
进一步地，电源导体102的规格可按客户要求选取，可以是12AWG(4mm 2)，10AWG(6mm 2)，8AWG(10mm 2)等，绝缘材料103和厚度满足0.6/1KV的电压要求。光纤芯根据客户要求，可以是单模或多模，且光纤芯数量也可按客户要求确定。
优选地，光电混合单元还包括至少一加强件104，加强件104与光单元101和电源单元混合在一起，可以设置一个或多个，起到增加线缆拉力的作用。
进一步地，本发明所揭示的一种光电混合金属丝铠装缆还包括阻水包带300，如图3所示，阻水包带300包裹在光电混合单元外，主要起到防止水进入混合缆内部的作用。
金属丝铠装100包裹在阻水包带300外，主要用于增强混合缆的机械强度，从而保护混合缆不会被外界的机械力破坏、被化学气体腐蚀等等。具体地，金属丝铠装100由金属线沿光电混合单元的轴向或径向绕裹于阻水包带外，金属线为单根金属丝或由多根金属丝并线绞合而成。优选地，金属丝的材质可以是铝丝、镁丝或铜丝等。
金属丝铠装绕裹的过程为：如果混合缆比较大，金属丝(如铜丝)根数较多，则先将金属丝按需要的根数先分组，然后并线绞合成多股金属线，然后将绞合好的金属线，装到笼绞机上；如果金属丝根数不多，则不需要并丝处理，直接装在笼绞机上(即直接为单根金属丝)；将挤好混合缆的半成品通过笼绞机中心孔放线，同时笼绞机的放线架开始旋转，将并好的金属线均匀的束满阻水包带的整个外表面。
由于采用金属丝绕裹铠装，所以弯曲性能良好，优于现有结构的金属波纹铠装缆；且金属丝梳绕铠装的生产加工工艺远远低于波纹铠装的生产加工工艺，大大降低了混合缆的生产成本。
进一步地，在尺寸设置上，金属丝铠装的外径同对应规格的同轴馈缆的铠外径。
外护套200包裹在金属丝铠装100外，外护套200的材质可优选阻燃，抗紫外线的室外绝缘材质，可以是PVC，PE或LSZH等材质。在尺寸上，外护套200的外径同对应规格的同轴馈缆的外径相同。由于金属丝铠装100的外径同对应规格的同轴馈缆的铠外径，并且外护套200的外径同对应规格的同轴馈缆的外径相同，因此可充分利用现有同规格的同轴馈缆的固缆夹、接地卡和吊网对本发明的光电混合缆进行安装，方便固定、接地，不需定制的固缆夹和吊网，且接地性能良好，优于现有的波纹铠装混合缆。
更进一步的，为了降低了混合缆的开剥难度，本发明在金属丝铠装100上设置开缆绳400。
结合图4和图5所示，分别为本发明光电混合缆的另一个实施方式的剖面示意图和立体图。与上述图3所示实施方式不同的是，该实施方式中，阻水包带包括第一阻水包带300和第二阻水包带500，以及在第一阻水包带300和第二阻水包带500之间增设了内护套600。
具体地，第一阻水包带300包裹在光电混合单元外，内护套600包裹在第一阻水包带300外，第二阻水包带500包裹在内护套600外，金属丝铠装100包裹在第二阻水包带500外。其中，第一阻水包带300和第二阻水包带500与上述实施方式中的材料相同，也是主要起到防止水进入混合缆内部的作用。内护套600与上述外护套200的材质相同，可优选阻燃，抗紫外线的室外绝缘材质，可以是PVC，PE或LSZH等材质。第一、第二阻水包带和内护套600的设置，更进一步增强了混合缆的防水性能。
在尺寸上，同样，金属丝铠装100的外径同对应规格的同轴馈缆的铠外径，并且外护套200的外径同对应规格的同轴馈缆的外径相同。
另外，与上述图3所示实施方式不同的是，该实施方式中，在内护套600和金属丝铠装100上均设置开缆绳400，用于降低混合缆的开剥难度。
本发明的技术内容及技术特征已揭示如上，然而熟悉本领域的技术人员仍可能基于本发明的教示及揭示而作种种不背离本发明精神的替换及修饰，因此，本发明保护范围应不限于实施例所揭示的内容，而应包括各种不背离本发明的替换及修饰，并为本专利申请权利要求所涵盖。
