由于高压分线器是电路回路节点,如果不采用分线器线路会杂乱无序,占有很大空间,不仅增加了成本,也降低了动力电池系统的空间利用率。并且安装和拆卸复杂,导致动力电池系统的回路的可维护性差,目前现有的分线器不具备快速散热功能,长时间工作,容易损伤分线器造成危险的发生;
为了让分线器快速散热,因此固定组件2采用高导热性的材料构成,或者固定组件的表面涂有高导热材料,然后通过固定组件2对第一扁带101和第二扁带102进行固定或者限制,通过固定组件2上的上的散热翅3和/或内部的冷却气体或冷却液进行高效的降温,从而保证了分线器长时间工作,不易因为高温造成损伤;
第一扁带101和第二扁带102固定连接,避免在工作时出现晃动或者移动的现象,导致杂乱无章,之后通过固定组件2进行固定,固定形式可为固定组件2内的卡接、焊接、螺接或一体注塑形式进行固定;
分线器1数量可为多个,多个分线器1通过其中第一扁带101或者第二扁带102电连接,实现分线功能。
在一些实施例中,高导热性材料为石英玻璃、碳化硅、云母、砂石、硅、石墨烯及衍生物或硅脂中的一种。
固定组件2的材质可为石英玻璃、碳化硅、云母、砂石、硅、石墨烯及衍生物或硅脂,以上材料导热好。
石英玻璃是由各种纯净的天然石英(如水晶、石英砂等)熔化制成。

在一些实施例中,第一扁带的材质为铜或铜合金,第二扁带的材质为铝或铝合金。
为了让第一扁带更好的进行导电,由于某些分线对导电传输效率不高,为了减轻重量,因此第二扁带的材质可选为铝或者铝合金,第一扁带和第二扁带的材质可随着实际需要进行更换。
在一些实施例中,第一扁带和第二扁带的至少部分表面设置有散热胶。
第一扁带和第二扁带上的散热胶,可以起到快速导热的功能,从而达到对第一扁带和第二扁带快速散热的效果。
在一些实施例中,第一扁带和第二扁带表面的散热胶厚度不同。
第一扁带和第二扁带上的散热胶,可以根据实际需要达到不同的厚度,达到不同的散热效果,从而避免资源的浪费,减少了生产不必要的损失。
在一些实施例中,第一扁带和/或第二扁带包括至少两个形状和/或横截面积不同的横截面。
在遇到狭窄的空间时,此结构的设计在不改变电能传输效果的同时还能够更好的与车辆的布线路径相适应。第一扁带和第二扁带可以为一体成型结构,相比于传统的采用两条不同的导体进行转接,此结构有效的降低了成本,提高安装效率。
在一些实施例中,固定组件上设置有至少一个散热翅。
安装在固定组件2上的散热翅3可以快速的进行散热,空气的流通会加速对散热翅3散热,从而加速带走固定组件2上的热,给分线器1进行降温。
在一些实施例中,散热翅数量为多个,多个散热翅在固定组件上并排布置或交叉布置或螺旋布置。
多个散热翅3可以加速对固定组件2进行散热,并排布置或交叉布置或螺旋布置可以更加快速的进行散热。
在一些实施例中,散热翅与固定组件一体成型。
与固定组件2一体注塑的散热翅3较为牢固,使用方便,无需安装,可以批量生产,节省人力。
在一些实施例中,散热翅的材质为金属材料,金属材料贴合或嵌入固定组件。
金属的散热翅3导热性能好,为了让散热翅3能更好的工作进行散热,因此散热翅3贴合或者部分嵌入固定组件2内,更大的接触面积,更加快速的导热,从而快速的降温。
在一些实施例中,固定组件上设置散热机构。
为了更好对分线器1进行散热,因此在固定组件2内设置散热机构,散热机构可以分线器1和固定组件2进行散热。
在一些实施例中,固定组件中设置至少一个管道,管道中流通冷却气体或冷却液。
固定组件2内具有一个或多个管道4,管道4内流通冷却用的冷却气体或者冷却液,冷却气体或者冷却液在管道4内的流通,可以带动端子组件和分线器1上的热,从而达到高效降温散热的功能。
在一些实施例中,第一扁带和第二扁带的自由端设置连接结构,连接结构上设置至少一个通孔或螺纹孔。
第一扁带101和第二扁带102的自由端设有连接结构5可以与外部元器件或者零部件进行连接,在连接结构5上设有通孔或者螺纹孔可以固定。
在一些实施例中,第一扁带和第二扁带上除了连接结构的部分设置绝缘层,至少部分绝缘层外表面与固定组件接触连接。
为了让分线器在使用的过程中避免发生危险,因此除了连接结构5处,其余部分均设有绝缘层6,起到保护的作用,绝缘层6的和端子组件相接触,避免端子组件与连接部相连接,发生危险。
在一些实施例中,至少有两个连接结构不在同一水平面内。
为了利用安装的空间,因此至少两个连接结构不处在同一水平面,便于安装。
在一些实施例中,第一扁带和第二扁带中至少一者含有至少一个弯折段。
第一扁带101和第二扁带102上的弯折段7可以让第一扁带101和/或第二扁带102拉伸延长或者调整连接结构5的方向及角度,便于安装。
在一些实施例中,弯折段的两端分别具有第一安装孔和相对于第一安装孔可移动的至少一个第二安装孔,第二安装孔的中心点相对于第一安装孔的中心点的可移动距离与第一 安装孔直径的比值范围为:0.25:1-1.65:1。
发明人为了选用不同的第二安装孔的中心点相对于第一安装孔的中心点的可移动距离与第一安装孔直径的比值范围连接导电件,来测试比值是否影响连接导电件以及导电是否充分,测试结果如表1所示。
表1,第二安装孔的中心点相对于第一安装孔的中心点的可移动距离与第一安装孔直径的比是否影响连接导电件和导电是否充分:
从表1可知,第二安装孔的中心点相对于第一安装孔的中心点的可移动距离与第一安装孔直径的比值范围为小于0.25:1的时候,移动距离太小,无法调整连接到导电件;第二安装孔的中心点相对于第一安装孔的中心点的可移动距离与第一安装孔直径的比值范围大于1.65:1的时候,安装孔孔径相对大,导电接触面积小,导电不充分;只有在比为0.25:1-1.65:1区间的时候,既可以导电充分又可以实现电连接,因此发明人选取了最适合的第二安装孔的中心点相对于第一安装孔的中心点的可移动距离与第一安装孔直径的比值范围为0.25:1-1.65:1
在一些实施例中,至少弯折段的材质为柔性材料。
为了让弯折段7工作时减少或者避免损伤,应采取柔性材料,弯折的过程中不易发生损伤或者影响导电。
在一些实施例中,固定组件与分线器的的接触面积不小于分线器表面积的18%。
为了选择更好的固定组件2与分线器1的的接触面积以让固定组件2与分线器1更好的进行工作,发明人进行了相关实验,实验方法为选用13根相同的分线器1,并通相同的电流,每个分线器上设置固定组件2,每个固定组件2与分线器的接触面积不同。在封闭的环境中,记录通电前的分线器1的温度和通电后的温度,并作差取绝对值。在本实施例中,温升小于50K为合格值。结果如表2所示。
表2:固定组件与型分线器的的接触面积对分线器温升的影响

如表2所示,当固定组件2与分线器1的的接触面积与分线器表面积的比小于18%时,温升大于50K,为不合格,因此发明人优选固定组件2与分线器1的的接触面积不小于分线器1表面积的18%。更好的对分线器进行固定的同时进行散热。
在一些实施例中,不同分线器的第二扁带的延伸方向相背设置。
为了节约车内安装空间,和分线器的空间利用,因此不同分线器内的第二扁带相反放置,可以更好的节约空间。
显然,上述实施例仅仅是为清楚地说明所作的举例,而并非对实施方式的限定。对于所属领域的普通技术人员来说,在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而由此所引伸出的显而易见的变化或变动仍处于本发明创造的保护范围之中。
