参照图1-2所示，为本实用新型提供的较佳实施例。
本实用新型提供的具有极柱的侧焊软连接片，运用在锂电池中，当然，亦可用于其他类型的电池中，不仅限于本实施例。
本实施例的具有极柱的侧焊软连接片，包括第一连接片101，该第一连接片101具有朝上布置的顶端面，第一连接片101的顶端面凸设有朝上延伸的极柱109，在实际装配中，第一连接片101的极柱109穿过顶盖；第一连接片101的一侧边朝外延伸有第二连接片100，该第二连接片100用于与电芯连接，第二连接片100相对于第一连接片101朝下弯折，并且，布置在电芯的侧边。
上述提供的具有极柱的侧焊软连接片，通过在第一连接片101的顶端面上凸设有极柱109，这样，在锂电池中，在第一连接片101对应的位置则不需要再独立设置极柱109，直接利用第一连接片101上的极柱109穿过顶盖则可，从而大大简化锂电池的结构，也大大降低锂电池的成本。
本实施例中，第一连接片101的顶端面凸设有凸起块，该凸起块形成上述的极柱109，参照图2所示，在极柱109的顶部凸设有连接柱108，可以利用该连接柱108与外部元件进行连接，从而实现锂电池与外部元件的连接。。
在凸起块的顶部凸设有焊接凸块110，这样，则便于第一连接片101的焊接。本实施例中，在凸起块上设置有两个上述的焊接凸块110，且该两个焊接凸块110分布在连接柱108的两侧，这样，焊接后的第一连接片101连接更加稳固。
本实施例中，第一连接片101具有与顶端面相背离的底端面，第一连接片101的底端面具有朝上凹陷布置的镂空区域107，通过设置镂空区域107，可以实现对软连接片的减重，实现锂电池的减重。
具体地，镂空区域107与极柱109之间呈上下对齐布置，这样，避免镂空区域107的设置导致影响第一连接片101强度的问题。并且，镂空区域107朝上延伸至极柱109的内部，优选地，镂空区域107的外形轮廓与极柱109的外形轮廓近似，且处于极柱109的包围范围内。
本实施例中，第一连接片101与极柱109为一体墩压成型，或者，也可以通过其他工艺一体成型。
在第一连接片101与第二连接片100的连接处的两侧分别设置有缺口106，这样，在不影响连接强度的前提下，可以进一步减重。
本实施例中，第二连接片100具有朝向电芯的内端面，第二连接片100的内端面设有凹槽103。
作为优选的实施例，凹槽103呈条状布置，且贯穿第二连接片100的下部，这样，则可以最大程度增大凹槽103的尺寸，进一步达到减重的效果。并且，第二连接片100的内端面设有两个上述凹槽103，两个凹槽103相间隔布置。
两个凹槽103隔开布置，且在两个凹槽103之间形成有凸条104，这样，在设置凹槽103的基础上，可以利用凸条104保证第二连接片100的强度要求。
本实施例中，第二连接片100的侧边朝外延伸有连接电芯的夹合片102，第二连接片100利用该夹合片102与电芯进行连接，并且，夹合片102的侧边缘呈倾斜状，这样，在不影响夹合片102的连接性能的基础上，进一步减少具有极柱的侧焊软连接片的重量。
夹合片102与第二连接片100的侧边连接，且夹合片102可以相对于第二连接片100相对摆动，在夹合片102与第二连接片100的连接处设有通孔105，这样，既可以使得夹合片102与第二连接片100之间摆动更加灵活，且进一步达到减重的效果。
以上所述仅为本实用新型的较佳实施例而已，并不用以限制本实用新型，凡在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的保护范围之内。
