在该实施例中蓄电池模块保护罩30具有开口或空隙1,所述开口或空隙如此如在图2中示出的现有技术的蓄电池模块保护罩30中的每个那样设置,从而蓄电池单元40的蓄电池单元端子11、12在蓄电池模块保护罩30的安装状态下能够通过空隙1或开口引导穿过。为了蓄电池单元40的蓄电池单元端子11、12的相互电气接触,蓄电池模块保护罩30在该实施例中纯示例性地具有蓄电池单元连接器8,该蓄电池单元连接器的开口相应于空隙1并且通过所述开口同样能够引导通过蓄电池单元端子11、12。蓄电池单元连接器8构成为,分别导电连接第一蓄电池单元40的蓄电池单元端子11或12与另一邻近第一蓄电池单元40的蓄电池单元40的蓄电池单元端子11或12。在图3的实施例中如此设置蓄电池单元连接器8,使得蓄电池单元40在安装蓄电池模块保护罩30的情况下串联连接。自然也能够实现具有蓄电池模块保护罩30的蓄电池模块50,在该蓄电池模块保护罩中如此设置蓄电池单元连接器8,使得蓄电池模块50的蓄电池单元40在安装蓄电池模块保护罩30的情况下相互并联连接或以其他方式连接。
在蓄电池模块保护罩30的该实施例中,集成到该蓄电池模块保护罩中的导电路径13可选择地与所有蓄电池单元连接器8导电连接。集成到蓄电池模块保护罩30中的导电路径备选地也能够仅仅与例如一个蓄电池单元连接器8或一个以上的蓄电池单元连接器8连接。此外,集成到蓄电池单元连接器8中的导电路径13在该实施例中纯示例性地与插头2连接,该插头与蓄电池模块保护罩30连接。例如传感器能够与这样一个插头2连接,从而通过集成到蓄电池模块保护罩30中的导电路径13能够将测量数据由蓄电池单元连接器8或通过蓄电池单元连接器由蓄电池单元端子11、12,通过导电路径13传送到传感器。
在该实施例中,蓄电池模块保护罩30纯示例性地构成为空间上注塑的电路载体。换言之,蓄电池模块保护罩30在该实施例中构成为所谓的模塑互连装置。此外蓄电池模块保护罩30在该实施例中纯示例性地构成为具有集成的结构化的金属化结构的高温热塑性塑料。在中间在蓄电池模块保护罩30中该蓄电池模块保护罩可选择地具有倒圆的开口,该开口在该实施例中纯示例性地相应于蓄电池单元包含罩的设计方案,也就是相应于蓄电池模块50的蓄电池单元40的蓄电池单元壳体的保护盖,从而在蓄电池模块保护罩30的安装状态下在该实施例中蓄电池模块保护罩30的中间开口之一分别在中间位于蓄电池单元保护盖的外侧之上。
在该实施例中,可选择地将密封件6喷注到在蓄电池模块保护罩30中的在中间设置的开口中。在蓄电池模块保护罩30的安装状态下,能够通过密封件6密封在蓄电池模块保护罩30与蓄电池单元40之间的间隙一方面以防液体由外进入到蓄电池模块50中而另一方面以防例如包含在蓄电池单元40中的电解质的化学试剂可能的流出。此外在该实施例中纯示例性地也将蓄电池单元连接器8喷注到蓄电池模块保护罩30中。而且这对于按照本发明的蓄电池模块50自然仅仅是可选择的。那么也能够实现具有蓄电池模块保护罩30的蓄电池模块50,在该蓄电池模块保护罩中仅仅喷注蓄电池单元连接器8或仅仅喷注密封件6或者既不喷注密封件6也不喷注蓄电池单元连接器8。
在该实施例中,构成密封件6的材料纯示例性地为三元乙丙橡胶(EPDM)。然而,构成密封件6的材料在按照本发明的蓄电池模块50的其他实施例中也能够包括其他材料或特别是其他橡胶弹性的材料。
图4示出了按照本发明的用于制造蓄电池模块50的蓄电池模块保护罩30的方法的一个实施例的视图。在该实施例中示出了五个方法步骤S1至S5,其中该实施例的第五方法步骤S5可选择地用于按照本发明的方法的实施。在第一方法步骤S1中制造用作电路载体的蓄电池模块保护罩坯件。在按照本发明的方法的该实施例中这纯示例性地借助于双色注塑也就是借助于双色注塑技术进行。对于用作电路载体的蓄电池模块保护罩坯件的制造自然也能够应用单色注塑技术或所谓的插入成型技术——其中涉及注塑的特殊形式——或者也能够应用完全其他的技术。蓄电池模块保护罩坯件例如已经能够具有完成的蓄电池模块保护罩30的形状,自然还没有用于导电路径13的结构或者还没有导电路径13自身。
在第二方法步骤S2中,全面地也就是说完全地金属化所述用作电路载体的蓄电池模块保护罩坯件。换言之,所述用作电路载体的蓄电池模块保护罩坯件完全以金属覆盖。这能够例如借助于化学或机械的PVD工艺,也就是借助于化学或机械、物理气相沉积实现,或者也能够通过完全其他的方式和方法实现。
随后结构化用作电路载体的蓄电池模块保护罩坯件的金属化结构也就是金属涂层。在第三方法步骤S3中,在蓄电池模块保护罩30的金属化涂层中对随后要实现的导电路径13进行结构化。在此能够采用3D掩膜或抗激光或激光直接工艺。此外结构化能够纯示例性地通过激光激活或所谓的涂底漆-移印工艺或者使用冲模、注塑工具、凸的弯曲薄膜或者以完全其他方式实现。
在第四方法步骤S4中,随后附加地金属化所述电路载体,由此在蓄电池模块保护罩坯件中实现导电路径13。这例如能够借助于印刷技术例如通过所谓的Flamecon技术、通过喷雾技术、喷墨技术、借助于化学或电镀工艺或通过完全其他的方式和方法例如通过热压实现。
在结束第四方法步骤S4之后已经能够应用由此产生的蓄电池模块保护罩30用于蓄电池模块50的保护。在该实施例中,在第五方法步骤S5中还可选择地将密封件6和蓄电池单元连接器8喷注到所述电路载体或蓄电池模块保护罩30中。此外可选择地也能够仅仅将密封件6而不将蓄电池单元连接器8或者仅仅将蓄电池单元连接器8而不将密封件6喷注到蓄电池模块保护罩30中。如上所述,自然也能够完全没有喷注密封件6和/或蓄电池单元连接器8的情况下实现按照本发明的方法。
因此,借助于按照本发明的方法能够制造按照本发明的蓄电池模块保护罩30连同密封件6、蓄电池单元连接器8以及集成到蓄电池模块保护罩30中的导电路径13。
