具体实施方式
本发明提供了一种碳纤维复合芯导线的接头结构，包括导线1和连接接头2，导线1包括线芯11和包覆线芯11的导电层12，连接接头2包括钢锚21和与钢锚21联接的引流线夹22，钢锚21的末段设有内层压接管23，内层压接管23外套有外层套管24，内层压接管23中设有供线芯11嵌入的空腔。
本碳纤维复合芯导线的接头结构中，通过加入内层压接管23和套住其的外层套管24，使得当碳纤维复合芯导线进行线夹压合时，压合的力需经两层管壁对导线施压，这样便将压合力分散到受力的钢锚上，保证了碳纤维复合芯导线受力的均匀性，提高了连接接头2对导线1的握力。本发明结构简单合理，锚接方便可靠，受力合理，广泛用于碳纤维复合芯导线的输电线路架设上。
第一个实施例，参照图1，包括钢锚21和与钢锚21联接的引流线夹22，钢锚21的末段与内层压接管23连接，且二者连成一体，内层压接管23外套有外层套管24，内层压接管23中设有供线芯11嵌入的空腔，线芯11与内层压接管23间还设有保护层。保护层为薄薄的铝制构件或者其他软性构件，保护层包覆线芯，并嵌入内层压接管23，保护层主要起保护作用，可防止线芯11在机械压合时受到损伤。钢锚21与内层压接管23为一体式，可使导线1受到的载荷直接传到钢锚21，可避免因安装所造成的错位使导线1受到其他方向的载荷而出现断裂的隐患。工作时，待联接的导线1的线芯11位于内层压接管23内，前端与钢锚21顶靠。导线1的机械性能通过内层压接管23及外层套管24传达到钢锚21上，并传达到终端，导线1的电气性能由外层套管24经过引流板，传达到引流线夹22上。另外，引流线夹22可以分0°和30°引流设置。钢锚21在远离内层压接管23的一端设有钢锚环25，钢锚环25用于与外设的绝缘子串连接。
第二个实施例，参照图2，包括钢锚21和与钢锚21联接的引流线夹22，钢锚21的末段联接有锚头26，锚头26的外面套有内层压接管23，内层压接管23中设有供线芯11嵌入的空腔，锚头26上在内层压接管23的内部设有若干道凹槽。具体地，钢锚21与锚头26为一体，钢锚21是通过引流板与引流线夹22连结的，引流板与外层套管24焊接为一整体。工作时，待联接的导线1的线芯11位于内层压接管23内，前端与锚头26顶靠。导线1的机械性能通过内层压接管23及外层套管24传达到锚头26上，并传达到终端，导线1的电气性能由外层套管24经过引流板，传达到引流线夹22上。另外，引流线夹22可以分0°和30°引流设置。钢锚21在远离锚头26的一端设有钢锚环24，钢锚环24用于与外设的绝缘子串连接。
作为本发明优选的实施方式，内层压接管23为铝合金构件，外层套管24为铝质或铝合金质构件。为了让后续的机械压合顺利，内层压接管23与外层套管24采用铝管作为原材料，这样其本身即具有了金属塑性，通过机械压合发生变形后，便可将线芯11与锚头26牢固地锚接在一起。当然，亦可采用其他类似的塑性材料来作为两个套管的材质，其亦属于本发明的等同变体。
作为本发明优选的实施方式，外层套管24的一端与钢锚21的末段套接并将内层压接管完全包覆在内，钢锚21上在外层套管24的内部设有若干道凹槽。这时，其另一端套在外设的待联接的碳纤维复合芯导线1的外层上，从而外层套管24的长度为从引流线夹22与钢锚21的联接点出发，直至碳纤维复合芯导线1的外层上且再延伸一段为止。进行机械压合的时候，外层套管24的两端均需压实。这时，内层压接管23承受了碳纤维复合芯导线1的95%剪切力，且该受力全部通过内层压接管23传递到钢锚21上。
钢锚21与锚头26上所设的凹槽，在进行压合联接的时候，铝质的内层压接管23与外层套管24就会产生变形并嵌入所述凹槽当中，这样便极大地增加了径向的摩擦力，让线芯11不容易滑脱。
作为本发明优选的实施方式，钢锚21的末段直径大于锚头26的直径。实际上，即指钢锚21的本体与锚头26构成轴肩台阶的结构。更进一步，可让钢锚21的末段直径大致等于内层压接管23的外径，锚头26的直径大致等于内层压接管23的内径，相应地，内层压接管23的内径亦要大致等于线芯11的直径。需注意的是，各个内外径的配合必须要在能够容许相互嵌套的前提下尽量紧密。
作为本发明优选的实施方式，线芯11是由2根或以上的碳纤维复合芯绞合而成，韧性更好提高。进一步，上述的碳纤维复合芯各层方向相反扭绞绞合。
作为本发明优选的实施方式，导电层12分为铝导体内层121和铝导体外层122，铝导体内层121是多条铝导体缠绕在线芯11外部，沿线芯11方向以螺旋形逆时针排列，构成铝导体内层121；铝导体外层122由多条铝导体沿线芯11方向以螺旋形顺时针排列，以反向的缠绕方式可防止导线1扭曲，紧密地缠绕在铝导体内层121上。
根据上述铝导体 2 各自 3 种的不同形状，可以将该碳纤维复合芯导线排列成如下所述的有九种不同的结构。
参照图 3，构成梯形铝导体内层121和梯形铝导体外层122；参照图 4，构成Z形铝导体内层121和Z形铝导体外层122；参照图 5，构成圆形铝导体内层121和圆形铝导体外层122；参照图6，构成梯形铝导体内层121和Z形铝导体外层122；参照图 7，构成梯形铝导体内层121和圆形铝导体外层122；参照图 8，构成Z形铝导体内层121和梯形铝导体外层122；参照图 9，构成 Z形铝导体内层121和圆形铝导体外层122；参照图 10，构成圆形铝导体内层121和梯形铝导体外层122；参照图11，构成圆形铝导体内层121和Z形铝导体外层122。
另外，除了上述九种实施例之外，还可以有如图 12、图 13 所示的另外两种实施例，参照图 12，铝导体内层121的铝导体为凹形，铝导体外层122的铝导体为与铝导体内层121配合的凸形。参照图 13，铝导体内层121的铝导体为凸形，铝导体外层122的铝导体为与铝导体内层121配合的凹形。在上述的凹、凸形结构中，所述的铝导体内层121的铝导体和铝导体外层122的铝导体的条数数量相等，两者一一对应，使铝导体内、外两层连接更加紧密。
装配时，先将碳纤维复合芯导线1的前端外层剥去一定长度，露出线芯11，然后对准线芯11与锚头26，套入内层压接管23，将内层压接管23与锚头26、线芯11整体压合，再在外表面套上外层套管24，即可锚固导线1。
当然，本发明创造并不局限于上述实施方式，熟悉本领域的技术人员在不违背本发明精神的前提下还可作出等同变形或替换，这些等同的变型或替换均包含在本申请权利要求所限定的范围内。
