其中，连接孔2121为沉孔，连接孔2121与盖板主体10的穿设孔101相对接。
具体地，第二极柱部22包括设置在穿设孔101外的第一极柱段和穿设在穿设孔101内的第二极柱段，第一极柱段和第二极柱段相互连接，第一极柱段设置在盖板主体10的内侧，第二极柱段远离第一极柱段的一端与第一极柱部21铆接。
具体地，绝缘部件30还包括绝缘主体32，绝缘主体32夹设在第一极柱部21和盖板主体10之间；绝缘主体32与绝缘凸缘部31连接。
在本申请的实施例中，绝缘凸缘部31的厚度大于或等于绝缘主体32的厚度；或者，绝缘凸缘部31与绝缘主体32为一体成型；或者，绝缘凸缘部31的厚度大于或等于绝缘主体32的厚度，绝缘凸缘部31与绝缘主体32为一体成型。
具体地，盖板主体10的靠近第一极柱部21的一侧设置有极柱沉槽11，绝缘部件30的至少部分设置在极柱沉槽11内。
本申请还提供了一种电池，包括电芯和盖设在电芯上的盖板组件，盖板组件为上述的盖板组件。
从以上的描述中，可以看出，本申请上述的实施例实现了如下技术效果：
本申请的盖板组件包括盖板主体10、极柱结构20和绝缘部件30，盖板主体10上设置有穿设孔101，极柱结构20的至少部分穿设在穿设孔101内，绝缘部件30的至少部分夹设在盖板主体10和极柱结构20之间；其中，极柱结构20具有位于盖板主体10外侧的第一极柱部21，第一极柱部21具有极柱外周面210；绝缘部件30具有环绕第一极柱部21设置的绝缘凸缘部31，绝缘凸缘部31具有绝缘外周面310；绝缘外周面310所在的曲形面位于极柱外周面210所在曲形面的外侧。这样，使得绝缘部件30包裹住极柱结构20，绝缘部件30卡在第一极柱部21(焊接铝块)与盖板主体10(光铝板)之间，将铆接铝块与光铝片两种金属材质的物料隔开，可以起到绝缘作用，可以有效避免电池在制作过程中短路的问题，避免绝缘失效。此结构可以避免铆接铝块和光铝片在实际加工过程中在边缘部位产生铝丝导通造成的短路，导致绝缘失效的问题。
需要注意的是，这里所使用的术语仅是为了描述具体实施方式，而非意图限制根据本申请的示例性实施方式。如在这里所使用的，除非上下文另外明确指出，否则单数形式也意图包括复数形式，此外，还应当理解的是，当在本说明书中使用术语“包含”和/或“包括”时，其指明存在特征、步骤、操作、器件、组件和/或它们的组合。
除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本申请的范围。同时，应当明白，为了便于描述，附图中所示出的各个部分的尺寸并不是按照实际的比例关系绘制的。对于相关领域普通技术人员已知的技术、方法和设备可能不作详细讨论，但在适当情况下，所述技术、方法和设备应当被视为授权说明书的一部分。在这里示出和讨论的所有示例中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它示例可以具有不同的值。应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
在本申请的描述中，需要理解的是，方位词如“前、后、上、下、左、右”、“横向、竖向、垂直、水平”和“顶、底”等所指示的方位或位置关系通常是基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，在未作相反说明的情况下，这些方位词并不指示和暗示所指的装置或元件必须具有特定的方位或者以特定的方位构造和操作，因此不能理解为对本申请保护范围的限制；方位词“内、外”是指相对于各部件本身的轮廓的内外。
为了便于描述，在这里可以使用空间相对术语，如“在……之上”、“在……上方”、“在……上表面”、“上面的”等，用来描述如在图中所示的一个器件或特征与其他器件或特征的空间位置关系。应当理解的是，空间相对术语旨在包含除了器件在图中所描述的方位之外的在使用或操作中的不同方位。例如，如果附图中的器件被倒置，则描述为“在其他器件或构造上方”或“在其他器件或构造之上”的器件之后将被定位为“在其他器件或构造下方”或“在其他器件或构造之下”。因而，示例性术语“在……上方”可以包括“在……上方”和“在……下方”两种方位。该器件也可以其他不同方式定位(旋转90度或处于其他方位)，并且对这里所使用的空间相对描述作出相应解释。
此外，需要说明的是，使用“第一”、“第二”等词语来限定零部件，仅仅是为了便于对相应零部件进行区别，如没有另行声明，上述词语并没有特殊含义，因此不能理解为对本申请保护范围的限制。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
