第一实施例first embodiment
参阅图1至图4所示,本申请第一实施例提供一种电池导片结构100a,可用以焊接于电池B的电极端BE。电池B可为18650型号的锂电池,并可应用于电动车、电钻或是其他电动工具上。电池并非本申请的范畴,因此不再加以赘述。此外,本申请不限制于18650型号的锂电池,也可应用于其他型号的圆柱状电池,仅需配合电池尺寸等比例缩小或放大电池导片结构。Referring to FIGS. 1 to 4 , the first embodiment of the present application provides a
电池导片结构100a包括一导片本体11、一连接部13以及至少两个电极连接片15a。导片本体11呈一环形,导片本体11可为多边形或是圆形,导片本体11的环形不在此限。需要说明的是,于本实施例中,导片本体11的环形是以圆形来进行说明。导片本体11的外围向相反的两方向向外延伸,形成至少一个固定部111,本实施例中以两个固定部111来进行说明。两个向相反的两方向向外延伸的固定部111定义一个纵长方向LD(如图2所示)。至少一个固定部111用于将电池导片结构100a固定于电池B上。电极连接片15a、导片本体11以及连接部13的材质可以选自如铜金属、镍金属或是硫化铜。The
连接部13呈一环形,连接部13可为多边形或是圆形,连接部13的环形不在此限。需要说明的是,本实施例中,连接部13的环形是以圆形来进行说明。连接部13是由导片本体11的内缘向内倾斜延伸。也就是说,连接部13与导片本体11并非位于同一平面上(如图3所示)。连接部13具有一高度差H,高度差H为导片本体11与电极连接片15a的垂直距离。The connecting
如图3所示,连接部13具有一斜度θ,连接部13的斜度θ为导片本体11与连接部13间所夹的角度,斜度θ的范围介于90度到150度之间,斜度θ较佳为135度。当斜度θ为90度时,导片本体11与连接部13两者呈现相互垂直。连接部13内缘直径IL是小于或是等于电池B的电极端BE直径BEL。也就是说,连接部13必定能对应于电池B的电极端BE(如图4所示)。As shown in FIG. 3 , the connecting
请复参图2及图3,两个电极连接片15a分别由连接部13的内缘向内延伸,两个电极连接片15a分别位于连接部13的内缘直径IL的两侧,其中,连接部13内缘直径IL可以是平行于导片本体11的纵长方向LD,使得电极连接片15a与导片本体11如图1所示,并且两个电极连接片15a于连接部13内缘形成一分离槽S1,该分离槽S1呈S型。此外,连接部13内缘直径IL也可以是不平行于导片本体11的纵长方向LD,使得电极连接片15a的延伸方向垂直于导片本体11的纵长方向LD。两个电极连接片15a朝相反方向向内延伸。2 and FIG. 3 again, the two
本实施例中,两个电极连接片15a并不相连,两个电极连接片15a之间具有一间距D(如图1所示)。其中间距D与电极连接片15a的长度L与宽度W的比为0.8:8:3。也就是说,间距D与电极连接片15a的长度比为1:10,且电极连接片15a的长度L与宽度W的比为8:3。在一较佳实施例中,间距D与电极连接片15a的长度比可为1:8,电极连接片15a的长度L与宽度W的比为8:2。此外,高度差H与间距D的比值介于为7/8至1之间。其中,两个电极连接片15a间较佳的间距D为0.8mm(毫米),且电极连接片15a较佳的长度L与宽度W分别为8mm(毫米)与3mm(毫米),高度差H介于0.7mm(毫米)至0.8mm(毫米)间。电极连接片15a的厚度约为0.2mm。连接部13的内缘圆周长与电极连接片15a的长度L的比为11.5:8,连接部13的内缘圆周长的较佳值为11.5mm。In this embodiment, the two
电极连接片15a仅有一端与连接部13相接,也就是说,电极连接片15a的另一端形成自由端。当一点焊机(图未示)对电极连接片15a与电池B的电极端BE进行点焊作业时,由于电极连接片15a仅有一端与连接部13相接,电极连接片15a的自由端得以通过支点(也就是电极连接片15a与连接部13相接处)向下靠近电池B的电极端BE,稳固电池导片结构100a与电池B的电极端BE的连接关系,避免产生脱落及接触不良的问题。Only one end of the
每一电极连接片15a上可以具有至少一个凸点结构151,凸点结构151的数量也可以是一个、二个、三个或是三个以上,凸点结构151是突出于电极连接片15a的一侧且凸点结构151突出于远离导片本体11的一侧。换句话说,凸点结构151是凸出于靠近电池B的电极端BE的一侧,使得凸点结构151与电极端BE进行点焊作业时,能更有效点焊。本实施例的每一电极连接片15a上具有两个凸点结构151。Each
第二实施例Second Embodiment

参阅图5至图7,本实施例提供一种电池导片结构100b,其包括一导片本体11、一连接部13以及四个电极连接片15b。四个电极连接片15b分别是由连接部13的内缘向内延伸。四个电极连接片15b的任两个电极连接片15b可以是两两相互对称(如图5所示)且四个电极连接片15b并不相连。四个电极连接片15b于连接部13内缘形成一分离槽S2,该分离槽S2呈梅花型。电极连接片15b的材质可以选自如铜金属、镍金属或是硫化铜。Referring to FIGS. 5 to 7 , the present embodiment provides a
连接部13具有一高度差H,高度差H为导片本体11与电极连接片15b的垂直距离。The connecting
每一电极连接片15b上具有至少一个凸点结构151。凸点结构151到连接部13的内缘具有一距离DD。电极连接片15b的长度L、宽度W与距离DD的比为4.3:2.4:2.7。在一较佳实施例中,电极连接片15b的长度L、宽度W与距离DD的比可为4.2:2.1:2.5。其中,电极连接片15b较佳的长度L与宽度W分别为4.3mm与2.4mm且距离DD的最佳值为2.7mm。因此,当进行点焊作业时,在距离DD为2.7mm及宽度W为2.4mm的条件下,电极连接片15b上的凸点结构151能被确保有效地与电池B的电极端B进行点焊。Each
