Abstract

本实用新型涉及一种电极耳外插拔式的动力锂电池塑壳，包括由上盖和下壳体构成的塑壳和正、负极耳，其特征是：所述下壳体两侧壁设有垂直凹槽，所述正、负极耳呈直角形折片，两片折片的水平片分别与电芯的正负极连接，折片的垂直片插过下壳体侧壁的横切口插入凹槽呈插拔式电极耳。有益效果：外插接式电极耳置于塑壳下壳体上，使极耳的路径缩短，内阻减小，避免了电芯间的短路。电极耳深陷于壳体凹槽中，外部不占空间，连接牢固，整体效果好，合格率大幅度提高。工艺简单、成本低。

Description

电极耳外插拔式的动力锂电池塑壳
技术领域
本实用新型属于动力锂电池，尤其涉及一种电极耳外插拔式的动力锂电池塑壳。
背景技术
动力锂电池开始推广使用环保型塑壳，当上盖与下壳体的连接采用粘合方式得以突破后，动力锂电池选择塑壳将成为市场主流产品。目前的动力锂电池内部结构是采用叠片式电芯，将每层叠片的正极和负极分别并联，再与正、负极耳连接，正、负极耳接在上盖表面。其缺点是制造难度很大，极易造成电芯间的短路，同时内阻加大。 
实用新型内容
本实用新型的目的在于克服上述技术的不足，而提供一种电极耳外插拔式的动力锂电池塑壳，外插接式电极耳置于塑壳下壳体上，使极耳的路径缩短，内阻减小，避免了电芯间的短路。 
本实用新型为实现上述目的，采用以下技术方案：一种电极耳外插拔式的动力锂电池塑壳，包括由上盖和下壳体构成的塑壳和正、负极耳，其特征是：所述下壳体两侧壁设有垂直凹槽，所述正、负极耳呈直角形折片，两片折片的水平片分别与电芯的正负极连接，折片的垂直片插过下壳体侧壁的横切口插入凹槽呈插拔式电极耳。 
有益效果：外插接式电极耳置于塑壳下壳体上，使极耳的路径缩短，内阻减小，避免了电芯间的短路。电极耳深陷于壳体凹槽中，外部不占空间，连接牢固，整体效果好。合格率大幅度提高。工艺简单、成本低。 
附图说明
图1是本实用新型的结构示意图； 
图2是图1的侧视图。
具体实施方式
下面结合附图及较佳实施例详细说明本实用新型的具体实施方式。如图所示，一种电极耳外插拔式的动力锂电池塑壳，包括由上盖1和下壳体2构成的塑壳和正、负极耳3，所述下壳体两侧壁设有垂直凹槽4，所述正、负极耳呈直角形折片，两片折片的水平片分别与电芯的正负极连接，折片的垂直片插过下壳体侧壁的横切口（图中未示）插入凹槽呈插拔式电极耳。 
组装时，正、负极耳其一端分别与可以与圆柱形电芯的正负极连接，当折片的垂直片部分穿过下壳体侧壁的横切口（图中未示）插入凹槽后，折片的水平片与壳体内侧齐平。   
以上所述，仅是本实用新型的较佳实施例而已，并非对本实用新型的结构作任何形式上的限制。凡是依据本实用新型的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本实用新型的技术方案的范围内。
