Description

带有蓄电池电极的蓄电池壳盖结构
本发明涉及带有蓄电池电极的蓄电池壳盖结构，特别是涉及电解液蓄电池用的蓄电池壳盖结构。
从现有技术，例如，从文献DE 102005030992A1、DE 4127956B4、DE 10301043B3、DE 68910878T2、DE 68913339T2、DE 19860198C2、DE 3417521C2、DE 69612537T2已知大量蓄电池电极结构。这些蓄电池电极结构设计得使其应该是对液体和气体密封的。
此外已知，在蓄电池电极上还安置传感器或测量导线。这时，出现下列基本问题：传感器或测量导线连接在蓄电池电极上的触点必须受到良好的保护。这种保护涉及化学和机械影响。例如，当腐蚀性电解液渗到触点上时，由于腐蚀，出现附加的电阻，使测量结果失真。此外，由于腐蚀，触点的机械强度
Figure BPA00001314897600011
可能减小，使得测量导线受到小的机械负载时可能中断。
然而，此外还需要防止机械损坏，因为在实践中，这样的蓄电池还会用高压射水清洁，这不应使触点受损。
在文献DE 19961311A1、DE 10118051A1、DE 3532044A1、DE 69616306T2、US 4572878、EP 1204165A1、WO 99/54744A1中公开了带有附加的连接线或带有传感器的蓄电池电极。已经表明，基本困难是，要同样良好地满足预防腐蚀性介质和机械损坏的要求，而为此的结构费用应该小。当要进一步保持外壳和电极包裹的公差时，满足标准蓄电池的要求特别困难。
因此，本发明的任务是，提供一种蓄电池电极结构，它要保证可靠地防水和防止测量导线所连接的蓄电池电极的机械损坏。一个特殊的要求在于，这样的预防措施的费用要小，而且应该要求与传统的蓄电池电极结构相比基本上不变。
这个任务借助于按照权利要求1的带有蓄电池电极的蓄电池壳盖结构解决。
以下的描述涉及一个唯一的蓄电池电极及其在蓄电池壳盖上的安置，尽管在一个蓄电池壳盖上安置多个蓄电池电极，然而它们的设计相同。
在该蓄电池壳盖中安置一个蓄电池电极，而且要用传统的方法固定，例如，靠形状配合夹紧。在蓄电池电极上至少设置一个测量电极段，该测量电极段在蓄电池壳盖平面上侧向地从蓄电池电极出发伸展。测量导线可用传统的方法连接在这个测量电极段上。在蓄电池电极四周，在蓄电池壳盖内设置一个用盖板(Abdeckung)覆盖的平凹座。该测量电极段处于这个凹座内。该凹座用弹性的密封基质填充。因此，该测量电极段、一段测量导线和特别是测量导线与测量电极段连接时所在的触点，用弹性的密封基质包围，并良好地预防液体和蒸汽。这样的密封基质是本领域技术人员已知的，故不必列举产品名称。由于这种密封基质的弹性，故在温度波动时不会出现丝状裂纹，例如腐蚀性电解液可能会渗入到这种丝状裂纹中。采用具有较高机械强度的固体浇铸料时存在这种危险。因此，设置一个由稳定的材料，最好由塑料制成的盖板，其覆盖该平凹座，其中该盖板的尺寸这样确定，使得高压射水本身或落在该盖板上的工具例如螺丝刀不会引起破坏。
按照权利要求2，该盖板可借助于夹子支架固定在该凹座上。这些夹子支架在制造壳盖时可以容易而且成本低廉地制造、非常可靠地保持，而且密封良好。
按照权利要求3，盖板借助于胶带固定在凹座上。它作为按照权利要求2的实施方式的替代方案，成本特别低廉。
下面将根据实施例和附图阐述本发明：
图1表示采用本发明的蓄电池壳盖的透视图；
图1a表示蓄电池电极。
在蓄电池壳盖2中蓄电池电极1用形状配合的方法固定。在该实施例中，在蓄电池电极1上设置两个测量电极段1c1、1c2，在每一个测量电极段上，例如，可通过钎焊、焊接或者借助于夹紧螺钉连接测量导线。在蓄电池壳盖2中围绕蓄电池电极1设置平凹座3，其可用盖板4覆盖。测量电极段1c1、1c2彼此相对，且在该凹座内水平延伸。凹座3最好完全用弹性的密封基质填充，使得测量电极段1c1、1c2完全嵌入密封基质中，这样预防水分和腐蚀性蒸汽。盖板4最好用与蓄电池壳盖2本身相同的材料制成，以保证可靠地预防机械负载。边缘侧的夹子支架5保证该盖板4非常可靠地连接在该凹座3上。该凹处6使测量导线(未示出)的延长成为可能。
所描述的实施方式是本发明的最佳实施方式。根据所描述的实施方式，本领域技术人员可以完全领会本发明的技术教导。显然，这些实施方式可以由本领域技术人员按照本发明的教导进一步发展、改变或加以组合。因此，没有明确地描述或示出的其他实施方式也落在以下权利要求书的保护范围之内。
