发明内容
本发明欲解决的问题
然而,与汇流条部件不同的连结端子也能够以组装到汇流条部件后与电线连接的方式形成,与此相反,也能够以连接电线后组装在汇流条部件的方式形成。例如,在前者的情况下,通过组装平板状的汇流条部件和连结端子,从而形成电线连接汇流条。电线连接汇流条例如在使平面彼此相互面对面层叠多个的状态下被搬送,因此,期望的是在其搬送时不施加无用的负荷,由此能够提高成品率。
因此,本发明的目的在于提供一种成品率优异的电线连接汇流条以及导电模块。
用于解决问题的技术方案
为了达成上述目的,本发明所涉及的电线连接汇流条包括:导电性的汇流条部件,其与排列具有正负各个电极端子的多个单体电池的电池模块的至少一个电极端子电连接;以及导电性的连结端子,其具有:第1端子部,其与所述汇流条部件物理且电连接;以及第2端子部,其与用于电连接所述汇流条部件以及电气连接对象物之间的电线物理且电连接,所述汇流条部件具有:平板状的汇流条主体,其与所述电极端子电连接;臂体,其是朝向相对于所述汇流条主体的基准平面的交叉方向从所述汇流条主体延伸的部位,并具有物理且电连接所述第1端子部的电气连接部;以及至少一个突出体,其朝向相对于所述基准平面的交叉方向从所述汇流条主体突出,所述突出体在沿着所述基准平面观察时,以在相对于所述基准平面的正交方向的从所述基准平面的突出量为所述正交方向的所述臂体和所述连结端子的连接体的从所述基准平面的最大突出量以上的方式形成。
此处,优选的是,在多个位置设置所述突出体的情况下,2个所述突出体分别以使所述臂体和所述连结端子的所述连接体存在于其间的方式配置。
另外,优选的是,所述第2端子部至少具有1组相对于所述电线的端部压接的2个筒片。
为了达成上述目的,本发明所涉及的导电模块包括:导电性的汇流条部件,其与排列具有正负各个电极端子的多个单体电池的电池模块的至少一个电极端子电连接;电线,其向多个所述单体电池的排列方向延伸,电连接所述汇流条部件以及电气连接对象物之间;以及导电性的连结端子,其具有:第1端子部,其与所述汇流条部件物理且电连接;第2端子部,其与所述电线物理且电连接;以及收纳部件,其收纳所述汇流条部件、所述电线以及所述连结端子,所述汇流条部件具有:平板状的汇流条主体,其与所述电极端子电连接;臂体,其是朝向相对于所述汇流条主体的基准平面的交叉方向从所述汇流条主体延伸的部位,并具有物理且电连接所述第1端子部的电气连接部;以及至少一个突出体,其朝向相对于所述基准平面的交叉方向从所述汇流条主体突出,所述突出体在沿着所述基准平面观察时,以在相对于所述基准平面的正交方向的从所述基准平面起的突出量为所述正交方向的所述臂体和所述连结端子的连接体的从所述基准平面起的最大突出量以上的方式形成。
发明效果
本发明所涉及的电线连接汇流条包括突出体,在搬送时,能够通过该突出体接受来自相邻的电线连接汇流条的负荷。另外,即使该电线连接汇流条在搬送时,相邻的电线连接汇流条与臂体、连结端子接触,也能够与该臂体、连结端子一起通过突出体接受来自相邻的电线连接汇流条的负荷。即,该电线连接汇流条能够将来自相邻的电线连接汇流条的负荷分散到臂体或者连结端子以及突出体。像这样,在该电线连接汇流条中,无论哪个都能够使搬送时施加给臂体、连结端子的负荷减少。因此,该电线连接汇流条在结束搬送后能够将臂体、连结端子的形状保持为搬送前的原来的形状。因此,本发明所涉及的电线连接汇流条与不具有突出体的部件比较能够提高成品率。另外,本发明所涉及的导电模块包括该电线连接汇流条,能够获得与该电线连接汇流条同样的效果。

具体实施方式
以下,根据附图,详细地说明本发明所涉及的电线连接汇流条以及导电模块的实施方式。需要说明的是,本发明不限于该实施方式。
[实施方式]
根据图1~图11,说明本发明所涉及的电线连接汇流条以及导电模块的实施方式之一。
图1以及图2的附图标记1表示本实施方式的导电模块。另外,图1以及图2的附图标记10表示本实施方式的电线连接汇流条。导电模块1与构成电池模块110的多个单体电池120中的至少一个电连接,并与该电池模块110一起构成电池组100。电池组100搭载于具有将转动机作为驱动源的车辆(电动汽车、混合动力车辆等)中,并用于相对于该转动机的供电等。首先,对该导电模块1的连接对象进行说明。
单体电池120包括单元主体121以及两个电极端子122(图2)。各个电极端子122以露出到外部的状态分别设置在单元主体121的任何位置,一侧是正极,另一侧是负极。各个电极端子122例如是设置在单元主体121的外壁面的板状部件,或者是从单元主体121的外壁面突出的柱状的极柱。在单元主体121具有多个外壁面的情况下,单体电池120的各个电极端子122可以配置在一个外壁面,也可以将配置有电极端子122的外壁面分到每个电极端子122。在电池模块110中,在各个单体电池120的任一侧的电极端子122排成一列并且另一侧的电极端子122也排成一列的状态下,将各个单体电池120连续地排列。因此,在该电池模块110中,由排成一列的电极端子122构成的电极端子群125被设置在两个位置。
在该电池模块110中,在每个各个电极端子群125电连接在单体电池120的排列方向相邻的两个电极端子122。进而,在该电池模块 110的全部电极端子122中,有2个没有与其他的电极端子122电连接。该独立的2个电极端子122一个为所谓的总正极,其中的另一个为所谓的总负极。
例如,本实施方式的单体电池120的单元主体121形成长方体。因此,本实施方式的电池模块110通过排列的多个单体电池120的集合体形成假想的长方体,并具有6个壁面。另外,在本实施方式的单体电池120中,正负各个电极端子122被配置在1个外壁面。因此,在本实施方式的电池模块110中,在形成长方体的6个壁面中的一个设置2个电极端子群125。另外,在本实施方式的单体电池120中,正负各个电极端子122被形成为板状。
需要说明的是,在电极端子122设置成为连接电线连接汇流条10 时的定位的基准的突起部122a(图2)。该突起部122a是从电极端子 122的露出平面(如后所述的连接电线连接汇流条10的平面)突出的柱状体,可以设置在所有电极端子122,也可以设置在特定的电极端子 122。在前者的情况下,可以将所有突起部122a设置为相同的形状,例如,也可以是正极用电极端子122和负极用电极端子122改变形状。另外,在后者的情况下,例如,只设置在正极用电极端子122和负极用电极端子122中的任一者。在该示例中,在整个电极端子122设置相同形状的突起部122a。
本实施方式的导电模块1相对于像这样构成的电池模块110与各个电极端子群125中的至少一个连接。该示例的导电模块1构成为分别与双方的电极端子群125电连接。
导电模块1包括电线连接汇流条10(图1~图7)。该电线连接汇流条10包括汇流条部件20和连结端子30(图3~图7)。进而,导电模块1包括与电线连接汇流条10成对的电线40(图7)。此外,导电模块1包括收纳该电线连接汇流条10和电线40的收纳部件50(图1 以及图2)。在该导电模块1中,至少设置1组使相互电连接的一对电线连接汇流条10和电线40的组合。在该示例中,在每个各个电极端子群125设置多组该组合。
电线连接汇流条10具有导电性,与电池模块110的至少一个电极端子122电连接,并且,与成对的电线40电连接。在该电线连接汇流条10中,导电性的汇流条部件20负责相对于电极端子122的电连接,导电性的连结端子30负责相对于电线40的电连接。在该电线连接汇流条10中,分别由金属等导电性材料形成该汇流条部件20和连结端子30。汇流条部件20和连结端子30可以分别由相同的导电性材料形成,也可以由不同种类的导电性材料形成。例如,应用于汇流条部件 20和连结端子30的导电性材料可以在分别考虑原价、形状等后决定。作为使用的导电性材料例如可以考虑铝、铝合金、铜、铜合金等。
汇流条部件20与电池模块110的至少一个电极端子122电连接,与连接对象的电极端子122的数量、形状、电池模块110上的配置等相对应地决定自身的形状。例如,汇流条部件20在电极端子122是板状的情况下以通过焊接与该电极端子122(激光焊接、超音波焊接、电阻焊接等)物理且电连接的方式形成。另外,在电极端子122为极柱的情况下,使电极端子122形成为柱状螺栓状,并且,在汇流条部件 20形成插通电极端子122的贯通孔。该情况的汇流条部件20和电极端子122通过使阴螺丝部件与该电极端子122螺合,从而使相互物理且电连接。
连结端子30与汇流条部件20物理且电连接,并且,与电线40物理且电连接。该连结端子30可以使用任何方法与汇流条部件20物理连接。例如,连结端子30可以相对于汇流条部件20压接并固定,也可以通过焊接(激光焊接等)相对于汇流条部件20固定。另外,该连结端子30可以使用任何方法与电线40物理连接。例如,连结端子30 可以相对于电线40压接并固定,也可以通过焊接、铜焊相对于电线40 固定。
此处,本实施方式的导电模块1包括作为该电线连接汇流条10在单体电池120的排列方向电连接相邻2个电极端子122的部件(以下,称为“电线连接汇流条10A”)、与总正极电连接的部件(以下,称为“电线连接汇流条10B”)、以及与总负极电连接的部件(以下,称为“电线连接汇流条10C”)(图1以及图2)。虽然各个电线连接汇流条 10A、10B、10C的连接对象的电极端子122的数量、电池模块110上的配置的形状不同,但在汇流条部件20具有汇流条主体21和臂体22 (图3~图7)方面没有变化。因此,以下列举电线连接汇流条10A的例子来说明电线连接汇流条10。
该示例的汇流条部件20将板状的铝作为母材,冲压成型为下述形状。
汇流条部件20具有与电极端子122电连接的平板状的汇流条主体 21(图3~图7)。该示例的汇流条主体21形成为长方形的平板状,在单体电池120的排列方向与相邻的2个电极端子122焊接。此处,如上所述,在电极端子122设置突起部122a。因此,在该示例的汇流条主体21上,在每个突起部122a形成用于避开该2个电极端子122的突起部122a的贯通孔21a(图3)。
另外,该汇流条部件20具有物理且电连接连结端子30的臂体22 (图3~图7)。该臂体22是朝向相对于汇流条主体21的基准平面21BL 的交叉方向从汇流条主体21延伸的部位。为了从基准平面21BL突出,该示例的臂体22从长方形的汇流条主体21的四个边部中的任一个延伸。此处,从位于相对于连接对象的2个电极端子122的排列方向的交叉方向的2个边部中的一个(边部21b)延伸(图3以及图5~图7)。
具体而言,该示例的臂体22具有:片体状的第1片部22a,其以从基准平面21BL突出的方式从边部21b立起;片体状的第2片部22b,其从该第1片部22a的突出方向侧的端部延伸;以及电气连接部22c,其设置在该第2片部22b的延伸方向侧的端部(图3以及图5~图7)。第2片部22b具有与包括基准平面21BL的设想平面平行的平面。电气连接部22c是物理且电连接连结端子30的后述第1端子部31的部位。该示例的电气连接部22c通过冲压成型层叠弯曲的2张片体,向汇流条部件20的连接对象的2个电极端子122的排列方向延伸。该电气连接部22c以通过第1端子部31夹入的方式被压接。该示例的臂体22从边部21b的大致中央延伸。
此处,电线连接汇流条10A用汇流条部件20具有朝向相对于基准平面21BL的交叉方向从汇流条主体21突出的至少1个突出体23(图 3~图7)。该突出体23在沿着基准平面21BL观察时,以来自相对于基准平面21BL的正交方向的从基准平面21BL的突出量H,为来自该正交方向的臂体22和连结端子30的连接体的从基准平面21BL的最大突出量HO以上的方式形成(图4~图6)。该示例的突出体23形成为片体状,以从基准平面21BL突出的方式从与臂体22相同的边部21b 立起。此处,使突出体23的突出量H比连接体的最大突出量HO大。另外,此处,在比边部21b的大致中央更靠近连结端子30的后述的第 2端子部32侧,并且,在比该第2端子部32更靠近汇流条主体21的角部21c侧设置突出体23(图3)。
连结端子30具有与汇流条部件20物理且电连接的第1端子部31 和与电线40物理且电连接的第2端子部32(图3~图8)。该示例的第 1端子部31形成为作为与汇流条部件20的电气连接部22c压接的压接部。另外,该示例的第2端子部32形成为作为与电线40的端部压接的压接部。该示例的连结端子30在同轴上配置该第1端子部31和第2 端子部32,以该轴线沿着汇流条部件20的连接对象的2个电极端子 122的排列方向的方式相对于电气连接部22c安装。
该示例的第1端子部31至少具有1组对置配置的2个片体状的筒片31a、31b(图3、图7以及图8)。各个筒片31a、31b夹着电气连接部22c,紧固压接在该电气连接部22c。此处,设置2组该一对筒片 31a、31b的组合。该各个组合沿着汇流条部件20的连接对象的2个电极端子122的排列方向排列。在一个的组合筒片31a、31b,为了避开第2片部22b,相对于一侧的筒片31a将另一筒片31b变短。另外,在另一个的组合筒片31a、31b,使各个形成为相同的长度。
该示例的第2端子部32至少具有1组对置配置的2个片体状的筒片32a、32b(图3、图7以及图8)。各个筒片32a、32b夹着电线40 的端部,并且,紧固压接在该电线40的端部。此处,设置2组该一对筒片32a、32b的组合。该各个组合沿着汇流条部件20的连接对象的2 个电极端子122的排列方向排列。另外,该各个组合相对于第1端子部31的各个筒片31a、31b的组合沿着该电极端子122的排列方向排列。一个的组合的筒片32a、32b被压接在电线40的端部的剥离的芯线41。另一个的组合的筒片32a、32b被压接在电线40的端部的包覆42(图7)。在双方的组合中,使各个筒片32a、32b的每对形成为相同的长度。
像这样,本实施方式的连结端子30相对于电气连接部22c、电线 40压接,因此,需要用于继续维持该压接力的弹簧性。因此,本实施方式的连结端子30将弹性极限高的铜合金的板材作为母材并冲压成型。
电线40被应用于电连接汇流条部件20以及电气连接对象物200 (图7)之间。该电线40在电池组100中向多个单体电池120的排列方向延伸。电气连接对象物200是指例如监视单体电池120的电池状态(电压、电流、温度等)的电池监视单元。因此,电线40被设置为用于检测单体电池120的电压的电压检测线。
收纳部件50由合成树脂等绝缘性材料形成。在该收纳部件50收纳电线连接汇流条10(汇流条部件20、连结端子30)和电线 40。该示例的收纳部件50在每个各个电极端子群125具有收纳汇流条部件20 的汇流条收纳室51、收纳连结端子30以及电线40的端部的端子收纳室52以及收纳电线40的电线收纳室53(图9)。
该示例的收纳部件50作为一个的电极端子群125侧的汇流条收纳室51具有第1汇流条收纳室51A、第2汇流条收纳室51B以及第3汇流条收纳室51C。第1汇流条收纳室51A是指收纳电线连接汇流条10A 的汇流条部件20的室。该第1汇流条收纳室51A形成在每个电线连接汇流条10A。第2汇流条收纳室51B是指收纳电线连接汇流条10B的汇流条部件20的室。第3汇流条收纳室51C是指收纳电线连接汇流条 10C的汇流条部件20的室。第2汇流条收纳室51B和第3汇流条收纳室51C分别各形成一个。另外,该示例的收纳部件50作为另一个电极端子群125侧的汇流条收纳室51具有每个电线连接汇流条10A的第1 汇流条收纳室51A。
端子收纳室52设置在各个电极端子群125侧的每个电线连接汇流条10A的连结端子30。在该端子收纳室52收纳电线连接汇流条10A 的连结端子30和与该连结端子30连接的电线40的端部。另外,在一个电极端子群125侧设置收纳电线连接汇流条10B的连结端子30和与该连结端子30连接的电线40的端部的端子收纳室52。但是,电线连接汇流条10C的连结端子30被收纳在邻接的电线连接汇流条10A用端子收纳室52。
电线收纳室53被设置在各个电极端子群125的每个室。在该电线收纳室53收纳从连结端子30引出的电线40。在一个电极端子群125 侧的电线收纳室53收纳与该电极端子群125的各个电极端子122电连接的各个电线40。另外,在另一个电极端子群125侧的电线收纳室53 收纳与该电极端子群125的各个电极端子122电连接的各个电线40。
在该示例的收纳部件50的每个电极端子群125设置封闭汇流条收纳室51、端子收纳室52以及电线收纳室53的各个开口(收纳口)的盖体54(图9)。
在该导电模块1中,将连结端子30安装在汇流条部件20并形成电线连接汇流条10。电线连接汇流条10A可以通过各个电极端子群125 共用。另外,可以准备电线连接汇流条10A在每个各个电极端子群125 将连结端子30的安装方向(说起来电线40的拉出方向)设为相反的方向的2种。在该导电模块1中,在形成电线连接汇流条10后,电线 40的端部与该连结端子30连接。在该导电模块1中,例如,在将收纳部件50配置在电池模块110的基础上,将带电线40的电线连接汇流条10全部收纳在收纳部件50,将各个电线40沿着电线收纳室53布线。各个汇流条部件20与电极端子122焊接。在该导电模块1中,经过这些工序,收纳部件50的盖体54被关闭。
该导电模块1在经过这些工序的基础上被安装在电池模块110,因此,在电线连接汇流条10的形成工序和电线40向连结端子30的连接工序之间包含电线连接汇流条10的搬送工序。在该搬送工序中,使汇流条主体21的平面彼此相互面对面从而层叠多个电线连接汇流条10 (图10),因此,如果该层叠方向沿着竖直方向,则越下侧的电线连接汇流条10负担越大的负荷。在图10中例举电线连接汇流条10A的例子。
然而,本实施方式的电线连接汇流条10包括之前示出的突出体 23,在搬送时通过该突出体23能够接受来自相邻的电线连接汇流条10 的负荷。另外,本实施方式的电线连接汇流条10在搬送时,即使相邻的电线连接汇流条10与臂体22、连结端子30接触,也能够与该臂体 22、连结端子30一起通过突出体23接受来自相邻的电线连接汇流条 10的负荷。即,该电线连接汇流条10能够将来自相邻的电线连接汇流条10的负荷分散到臂体22或者连结端子30以及突出体23。像这样,在本实施方式的电线连接汇流条10中,无论哪个都能够使搬送时施加给臂体22、连结端子30的负荷减少。因此,本实施方式的电线连接汇流条10在结束搬送后能够将臂体22、连结端子30的形状保持为搬送前的原来的形状。因此,本实施方式的电线连接汇流条10与不具有突出体23的部件比较能够提高成品率。另外,本实施方式的导电模块1 包括该电线连接汇流条10,能够获得与该电线连接汇流条10同样的效果。
然而,本実施形态 的电线连接汇流条10可以在多个位置设置突出体23。在多个位置设置突出体23的情况下,优选的是,2个突出体23 以使臂体22和连结端子30的连接体存在于之间的方式分别配置在边部21b(图11)。优选的是,该2个突出体23使各个突出量H比连接体的最大突出量HO大。电线连接汇流条10通过配置该2个突出体23 和设定突出量H,从而能够减少相对于臂体22、连结端子30的相邻的电线连接汇流条10的接触的可能性,因此,能够进一步提高成品率。
如上所示,在本实施方式中,通过在电线连接汇流条10设置突出体23,从而能够获得成品率优异的电线连接汇流条10和导电模块1。
