对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为说明书的一部分。
在这里示出和讨论的所有例子中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它例子可以具有不同的值。
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。
本发明提供一种铜铝分线连接结构，如图1-图9所示，包括：连接件、第一套筒13和第二套筒14，连接件包括固定部12，固定部12包含第一固定面17和第二固定面18，分别连接第一套筒13和第二套筒14，第一套筒13或第二套筒14至少一个的材质含有铝。本发明的第一套筒13和第二套筒14通过摩擦焊的方式与固定端连接，可以根据不同的生产条件及产品需求将铝导线与铜导线或与铝导线或与铜端子进行连接，较为方便；而且可以用较短的时间完成铝导线与其他材质导线的连接，不需要重新增加或设计连接件。
在一些实施方式中，连接件还包括连接部11，连接部11为片状结构。连接部11可以用于将铜铝分线连接结构与其他用电器进行连接。
在一些实施方式中，固定部12为片状结构，如图1所示，包括相对设置的第一固定面17和第二固定面18，以及与第一固定面17和第二固定面18相邻的侧面，连接部11与侧面连接。第一固定面17与第一套筒13连接，第二固定面18与第二套筒14连接。
在一些实施方式中，固定部12为柱状结构，包括相对设置的第一固定面17和第二固定面18，以及与第一固定面17和第二固定面18相邻的侧面，连接部11与侧面连接。具体地，连接部11可以设置在固定部12侧面的中间，如图2所示，也可以设置在固定部12侧面的一端，如图3所示，具体可根据装配时的需要设置。
在一些实施方式中，第一固定面17和第二固定面18平行或呈预定角度。根据实际应用需要，通过调整第一固定面17和第二固定面18之间的角度设置，使对应连接的第一套筒13和第二套筒14平行或呈预定角度，如图4所示，满足线束装配的需求。
在一些实施方式中，第一固定面17和第二固定面18之间的夹角为0°-90°。通过设置不同的夹角，可以使两端分别固定的线缆呈现不同的角度。夹角为0°时，第一固定面17和第二固定面18相互平行，此时第一套筒13和第二套筒14平行；夹角在0°-90°之间，第一套筒13和第二套筒14可以呈现不同角度的连接方式；当夹角为90°时，第一固定面17和第二固定面18相互垂直，此时第一套筒13和第二套筒14相互垂直，用于分别连接相互垂直的线缆。
在一些实施方式中，连接部11的平面与第一套筒13或第二套筒14的轴向方向垂直，如图6所示。
在一些实施方式中，连接部11的平面与第一套筒13或第二套筒14的轴向方向平行，如图5所示。在具体实施中，可以根据线缆的安装方向调整连接部11的设置方向。
在一些实施方式中，连接部11的平面与第一套筒13或第二套筒14的轴向方向可以为0°-90°之间的任意预定角度。
在一些实施方式中，还包括弯折部112，如图7所示，弯折部112两端分别连接连接部11和固定部12，并使连接部11与固定部12的轴向方向呈预定角度。
在一些实施方式中，连接部11与固定部12的轴向方向的夹角为45°-180°。当夹角小于45°时，连接部11趋近于弯折部112，不便于将连接部11与用电装置进行连接，连接部11与固定部12的轴向方向夹角最大为180°，即连接部11与固定部12平行，具体实施例中，连接部11弯折方向不固定，可以根据实际安装需要设置。
在一些实施方式中，连接部11上设置安装孔111，用于与用电装置连接。具体地，可以利用螺栓结构通过安装孔111将连接结构与用电装置连接。
在一些实施方式中，第一套筒13靠近固定部12的一端为封闭结构，第一套筒13在靠近固定部12的径向直径小于远离固定部12的径向直径；第二套筒14靠近固定部12的一端为封闭结构，第二套筒14在靠近固定部12的径向直径小于远离固定部12的径向直径。具体地，将线缆固定于第一套筒13时，剥除表面绝缘层的线芯15部分设置在第一套筒13径向直径较小处，线缆及线芯装配至第一套筒内部后，使用压接机，将第一套筒与线缆及线芯冲压为一体，采用压接的方式可以提高量产率，利用自动压接机能够迅速大量的制造稳定品质的产品。
在一些实施方式中，第一套筒13的最小内径小于等于第二套筒14的最小内径，如图8和图9所示。在具体实施例中，由于负载功率不同，需要不同直径的线缆传递电流，通过调整第一套筒13和第二套筒14的最小内径，可以将不同直径的线缆连接，满足性能及装配要求。
在一些实施方式中，连接部11与固定部12一体成型，简化加工步骤，提高连接件的稳定性，增强耐用性。
在一些实施方式中，第一套筒13和第二套筒14通过摩擦焊的方式分别固定于第一固定面17和第二固定面18。摩擦焊的方式是指利用工件接触面摩擦产生的热量为热源，使工件在压力作用下产生塑性变形而进行焊接的方法。
在一些实施方式中，连接部11表面至少部分设置镀层，镀层材质含有镍、镉、锰、锆、钴、锡、钛、铬、金、银、铝、锌、锡铅合金、银锑合金、钯、钯镍合金、石墨银、石墨烯银和银金锆合金中的一种或多种。连接部11表面设置镀层，可以提高连接部 11的耐腐蚀性，提高导电性能，并且能延长连接部11的使用寿命，避免经常需要更换和维护。
在一些实施方式中，固定部12的材质中含有铜，以获得更好的导电性能，优选的，固定部12的材质为碲铜合金，使固定部12具有良好的导电性和易切削性能，保证电学性能也能提高加工性，同时，碲铜合金的弹性也很优良。
在一些实施方式中，固定部12的表面具有镀层，是为了提高耐腐蚀性，提高导电性能，更好的延长固定部12的使用寿命。
虽然已经通过例子对本发明的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上例子仅是为了进行说明，而不是为了限制本发明的范围。本领域的技术人员应该理解，可在不脱离本发明的范围和精神的情况下，对以上实施例进行修改。本发明的范围由所附权利要求来限定。
