为实现以上目的，本实用新型通过以下技术方案实现：

所述压接部与所述端子主体接触，所述第一压接翼板环抱或抵压所述压接部形成压接区域，所述压接部在所述压接区域中具有多层结构。
根据本实用新型的一个技术方案，所述压接部为平板状，并沿所述导体主体的长度方向对折设置。
根据本实用新型的一个技术方案，所述压接部为横截面为U型或V型截面的结构受压而成。

根据本实用新型的一个技术方案，所述转接端子还设置有一对第二压接翼板，所述第二压接翼板设置于所述端子主体上并突出于所述端子主体设置，所述一对第二压接翼板环抱所述绝缘皮将所述端子主体与所述连接部连接。
根据本实用新型的一个技术方案，所述端子主体围成一容置槽，所述端子主体上分别设置有一对第一压接翼板和一对第二压接翼板；所述连接部和所述压接部位于所述容置槽内，通过压接使所述第一压接翼板将环抱所述压接部，通过压接使所述第二压接翼板环抱所述绝缘皮；所述第一压接翼板和所述第二压接翼板将所述转接端子和连接端及绝缘皮连接。
根据本实用新型的一个技术方案，所述柔性扁平线缆数目为多个，并排连接设置；每个柔性扁平线缆的连接端连接有一个转接端子；每个转接端子的所述容置槽具有一开口；所述多个柔性扁平线缆的排列方向与所述容置槽的开口方向非重合地设置。
根据本实用新型的一个技术方案，所述多个柔性扁平线缆的排列方向与所述容置槽的开口方向垂直设置。

具体实施方式
如图1、图2和图3所示，柔性扁平线缆组件100，其包括柔性扁平线缆110 和转接端子120。所述柔性扁平线缆110包括绝缘皮118、导体主体111、连接端112。所述绝缘皮118包裹导体主体111，部分导体主体111露出绝缘皮118 之外。导体主体可根据实际使用要求选择，比如铝或铜等适合弯曲的导体。所述导体主体111整体为柔性，适合弯曲以适应使用场合的空间。所述连接端112包括连接部113和压接部114。所述连接部113与所述压接部114为一体结构。导体主体111、连接部113及压接部114依次连续。根据本实用新型的方案，所述连接端112与所述导体主体111一体设置。所述连接端112为经带状或平板状导体折弯、冲压而成。连接端112与导体主体111共同组成导体。在未压接之前，导体的端部与导体主体111均为平板状或带状，自导体端部起选取一定长度，采用折弯工艺加工。导体的端部经折弯后，压接部114横截面为U型或V 型，且具有第一开口115。使压接部114受压后变形，成为双层的结构，即为一块平板对折后形成的双层结构。冲压后，双层的压接部114上下两层相接触。由于压接部114为采用与导体主体111相同的结构折弯、冲压而成双层结构，所以，压接部114厚度大于导体主体111的厚度。
连接部113的结构和形状无特别限制，其可以为平板状，也可以适应压接部114的形状设置。比如，压接部114横截面为U型或V型时，连接部113边缘向中间逐渐收缩，平滑过渡为导体主体111的平板状。连接部113也可以直接设置为平板状。连接部113与端子主体111内部的导体电连接。
所述转接端子120包括端子主体121、一对第一压接翼板124、一对第二压接翼板125。转接端子120为金属件冲压弯折而成。端子主体121整体结构可视使用要求确定，其既可以是公端子，也可以是母端子。如图所示的示例中，转接端子120为母端子。端子主体121设置其中一段围成一容置槽123。容置槽123 具有一第二开口127。容置槽123用于容纳压接部114及部分绝缘皮118。端子主体121上设置有一对第一压接翼板124。第一压接翼板124与端子主体121连接并突出于端子主体121。一对第一压接翼板124相对设置。第二压接翼板125 与端子主体121连接并突出于端子主体121。一对第二压接翼板125相对设置。
转接端子120与连接端112及绝缘皮118压接连接。具体地，如图4所示，压接部114置于容置槽123内，第一开口115朝向与第二开口127朝向非重合地设置，优选为两个开口垂直。例如，第二开口127朝上设置，则第一开口115 朝左或朝右设置。压接部114位于一对第一压接翼板124之间。如图5所示，一对第一压接翼板124受压向压接部114方向变形，从两个方向环抱压接部114 或者端部抵顶在压接部124表面。一对第一压接翼板124受压后变形，形成压接区域。在该压接区域，横截面为U型的压接部114受压后层叠、形成具有两层的结构。在如图所示的示例中，压接方向为上下方向，沿上下方向，压接部114 为多层，如图所示为两层结构，且两层相互接触。一对第一压接翼板124将压接部114与端子主体121连接。在如图所示的优选示例中，一对第一压接翼板124 受压变形后，端部抵顶在压接部114表面，并使其表面微变形以增强抵顶力。
部分绝缘皮118位于一对第二压接翼板125之间，一对第二压接翼板125 受压向绝缘皮118方向变形，从两个方向环抱绝缘皮118。一对第二压接翼板 125将绝缘皮118与端子主体121连接。在如图所示的优选示例中，一对第二压接翼板125受压变形后，环抱绝缘皮118。
一个或多个柔性扁平线缆组件100、支架以及汇流排组成电池包连接组件，用于新能源汽车的电池中。多个柔性扁平线缆组件100的绝缘皮118并排设置，相互粘接。汇流排设置在支架上，汇流排与所述电池芯电连接。柔性扁平线缆组件100的导体主体118与汇流排电连接。
为增加利用率，柔性扁平线缆中的导体尽可能薄而窄。当连接端与导体主体一体成型设置时，薄而窄的连接端无法满足连接强度需要的保持力，压接过程中因压接操作而折断，或者使用过程中因无法提供较强的保持力而导致脱落。
本实用新型中的柔性扁平线缆组件及电池包连接组件，压接部对折设置，增强了与转接端子压接连接的压接部的厚度，既不会在压接过程中损坏，还能够在压接完成后提供足够的保持力，确保使用过程中的连接的牢固性，使用安全且方便。使用本实用新型中的柔性扁平线缆组件，其可以代替刚性线路板及柔性线路板，既可以降低电池包的厚度，又可以降低生产成本，使电池进一步发展以满足新能源汽车的使用要求。
以上仅为本实用新型较佳的实施例，并不用于局限本实用新型的保护范围，任何在本实用新型精神内的修改、等同替换或改进等，都涵盖在本实用新型的权利要求范围内。
