有屏蔽要求的快速充电线束的常见设计是使用高压屏蔽铜导线。如图1所示,铜导线100的两端连接充电座连接器110和电池连接器120,充电座连接器110用于和外部的充电插头(未示出)连接,电池连接器120用于和电池组或电池组的配电盒连接,多根铜导线100用于传递电力。
充电座连接器110一般被设于车身侧面,例如车身左后或右后,靠近后轮的位置。电池组则通常被设于车身底盘上。因此,充电座连接器和电池组之间的铜导线有较大的长度。由于铜是一种密度较大的材料,且成本亦较高,因此图1所示的线束中,铜导线100的重量和制造成本均会影响新能源汽车降本减重的开发需求。

实施例1:
一种充电线束,如图2所示,包括:由多个铝棒1构成的导电段;连接于铝棒的第一端的充电座连接器2;连接于铝棒的第二端的电池连接器3。充电座连接器2的尾端接出铜线缆4,铜线缆4的末端和铝棒1的第一端焊接。电池连接器3的尾端接出铜线缆4,铜线缆4的末端和铝棒1的第二端焊接。
其中,充电线束包括两根铝棒1,铝棒1可以预成形为特定的形状以适应于在车体内的安装。线束两端的充电座连接器2和电池连接器3的尾端仍用铜线缆4接入,然后铝棒1的两端和上述两个连接器尾端的铜线缆4中的铜导体形成电连接,从而完成从充电插座到电池组/电池组配线盒的电传输路径。
如图3所示,本实施例中,铜线缆4从内到外,依次包括铜线芯4-1、铜缆绝缘层4-2、铜缆屏蔽层4-3、铝箔4-4和护套4-5。可以理解的是,铝箔4-4可以设置在铜缆屏蔽层4-3外侧,作为一种替代,其也可以在铜缆屏蔽层4-3的内侧。
如图4所示,本实施例中,铝棒1包括圆形实心铝芯1-1、线束绝缘层1-2、线束屏蔽层1-3,此外,还可以有图中未示出的保护层。圆形实心铝芯1-1的横截面积可为120mm2。线束绝缘层1-2可通过PA12、XLPE或PVC材料挤塑。线束屏蔽层1-3可以是编织层、编织套管,或者铝带或铜带的缠绕结构。保护层可以是套管或管道。
关于铝棒1和铜线缆4的连接结构,如下:
如图5所示,一段铜缆屏蔽层4-3裸露在铝箔4-4外形成外露铜缆屏蔽层4-3,一段铜缆绝缘层4-2裸露在外露铜缆屏蔽层4-3外形成外露铜缆绝缘层4-2,一段铜线芯4-1裸露在外露铜缆绝缘层4-2外形成外露铜线芯4-1,外露铜线芯4-1被设置为扁平铜端子;在铜线缆4与铝棒1的连接处,一段线束绝缘层1-2裸露在线束屏蔽层1-3外形成外露线束绝缘层1-2,一段圆形实心铝芯1-1裸露在外露线束绝缘层1-2外形成外露圆形实心铝芯1-1,外露圆形实心铝芯1-1被设置为扁平铝端子;扁平铜端子和扁平铝端子焊接连接。
具体操作时,在铜线缆4与铝棒1的连接处,将铜线缆4的端部剥开,从而在端部露出一段铜线芯4-1,在铜芯线后一段距离露出一段铜缆绝缘层4-2,在铜缆绝缘层4-2后一段距离露出一段铜缆屏蔽层4-3;同样,将铝棒1的端部剥开,从而在端部露出一段圆形实心铝芯1-1,在圆形实心铝芯1-1后一段距离露出一段线束绝缘层1-2,在线束绝缘层1-2后一段距离露出一段线束屏蔽层1-3;将外露的铜线芯4-1加工制作为扁平铜端子,将外露的圆形实心铝芯1-1加工制作为扁平铝端子,扁平铜端子和扁平铝端子以诸如波峰焊的技术焊接连接。
如图6所示,在扁平铜端子和扁平铝端子的焊接互连部分5外包覆有第一热缩管6,第一热缩管6包覆的区域还包括焊接互连部分5两端的外露铜缆绝缘层4-2和外露线束绝缘层1-2。
如图7所示,在第一热缩管6外包覆有编织屏蔽层7,编织屏蔽层7包覆的区域还包括第一热缩管6两端的铜缆屏蔽层4-3和线束屏蔽层1-3,编织屏蔽层7与第一热缩管6两端的铜缆屏蔽层4-3和线束屏蔽层1-3在一段距离内产生交叠。
如图8所示,本实施例中,在编织屏蔽层7与第一热缩管6两端的铜缆屏蔽层4-3和线束屏蔽层1-3的交叠区域上缠绕有铝箔带8。其他实施方式中,作为一种替代方式,不使用铝箔带8,而是在编织屏蔽层7与第一热缩管6两端的铜缆屏蔽层4-3和线束屏蔽层1-3的交叠区域上压接有铜环端子。
如图9所示,本实施例中,在铜线缆4与铝棒1的连接处,编织屏蔽层7外还包覆有第二热缩管9,第二热缩管9的一端还包覆铜线缆4的一段护套4-5。此外,上文所提到的铝箔带8为铝箔胶带,铝箔胶带的一面带铝箔,用于和编织屏蔽层7接触,另一面涂胶,用于和第二热缩管9接触。此外,本实施例中,考虑到铝棒1还包括包覆在线束屏蔽层1-3外的保护层,因此,在铜线缆4与铝棒1的连接处,第二热缩管的两端还包覆铜线缆4的一段护套4-5和铝棒1的一段保护层。
为了减重降本,在充电线束中,可以使用铝棒1代替铜线缆4,可节省车内空间,减轻重量和降低成本,可普遍适用于新能源汽车。
考虑到充电座连接器2和电池连接器3的尾端使用铜线缆4,本申请设计了铝棒1和铜线缆4之间的连接方案,如下:
铜线芯4-1和圆形实心铝芯1-1锻压成扁平后焊接,套热缩管做绝缘层,编织屏蔽层与铜缆屏蔽层4-3和线束屏蔽层1-3有一个接触重叠区,在重叠区缠绕胶带或压接铜端子,从而实现编织屏蔽层与铜缆屏蔽层4-3和线束屏蔽层1-3连接,最后再套热缩管进行密封防水。本申请设计的连接方案工艺简单,成本较低。
以上详细描述了本实用新型的较佳具体实施例。应当理解,本领域的普通技术人员无需创造性劳动就可以根据本实用新型的构思做出诸多修改和变化。因此,凡本技术领域中技术人员依本实用新型的构思在现有技术的基础上通过逻辑分析、推理或者有限的实验可以得到的技术方案,皆应在由权利要求书所确定的保护范围内。
