第三电连接器60，其配置于电路板30，并包括至少一接口，所述接口适于与外部的用电设备电连接，使得来自电芯的电力可以通过第三电连接器60提供给用电设备；
第一连接件70，其适于与第一用电设备200a闩锁连接；
第一连接件70设置于第三侧面10d，其长度方向与第三侧面10d的长度方向垂直。
进一步地，第三侧面10d至少部分为连续延展的平面，以便于与用电设备匹配面配合。
进一步地，还包括第二连接件80，第二连接件80适于与第二用电设备200b闩锁连接；且第一连接件70与第二连接件80与与之对应的用电设备200闩锁连接时，二者互不干涉。
进一步地，第二连接件80设置于第三侧面10d。
进一步地，第二连接件80的长度方向与第三侧面10d的长度方向垂直，并且与第一连接件70的长度不同。
进一步地，第一连接件70和第二连接件80为闩槽，所述用电设备匹配有与之对应的闩锁；
当所述闩锁与所述闩槽之一闩锁连接时，其闩锁行进路径上，所述闩锁与另一所述闩槽不匹配；和/或
当所述闩锁与所述闩槽之一解锁脱离时，其解锁脱离路径上，所述闩锁与另一所述闩槽不匹配。
本技术方案配置第三连接器60，该第三连接器60包括至少一接口，其接口可以供不同的用电设备用电，如3C类电子设备或者大电流动力工具等，并且基于特定的电池包形状，将与用电设备匹配使用的连接件设置于特定的电池包侧面上，方便使用和利于电池包外形设计美观。
请继续参照图1至图9所示，一种多用电池包100，其包括：
壳体10，以及内置于壳体10中的电芯20和电路板30；
第一电连接器40，其将电芯20正负极的一端与电路板30相连接；
第二电连接器50，其将电芯20正负极的另一端与电路板30相连接；
电动工具用电的放电接口60a，其配置于电路板30，并包括至少一接口，所述接口适于与外部的用电设备电连接，使得来自电芯的电力可以通过该电动工具用电的放电接口60a提供给电动工具用电设备；
第一连接件70，其适于与第一用电设备闩锁连接，并靠近电动工具用电的放电接口60a；
第二连接件80，其适于与第二用电设备闩锁连接，并远离电动工具用电的放电接口60a；
当第二连接件80对应与第二用电设备闩锁连接或解锁脱离时，第一连接件70与第二用电设备不发生干涉。
具体地，第一连接件70为第一闩槽，第二连接件80为第二闩槽，第一用电设备匹配有对应的第一闩锁，第二用电设备匹配有对应的第二闩锁；
当第二闩槽对应与第二闩锁闩锁连接或解锁脱离时，第一闩槽与第二闩锁不匹配。
更具体地，参照图9所示，第一闩槽和第二闩槽的呈条形状，且二者的长度方向均与多用电池包的长度方向垂直，同时，第二闩槽的长度大于第一闩槽的长度。
如此，当第二闩槽对应与第二用电设备闩锁连接或解锁脱离时，由于第二闩槽的长度大于第一闩槽的长度，第二用电设备与第二闩槽对应的闩锁也必然较第一闩槽的长度大，进而实现，虽然第一闩槽在第二闩槽与第二用电设备对应的线性路径段L2上，但由于第二用电设备的闩锁较第一闩槽的长度大，因此不与之相匹配，如此，不会发生干涉。
请继续参照图1至图9所示，一种多用电池包，其包括：
壳体10，以及内置于壳体10中的电芯20和电路板30；
第一电连接器40，其将电芯20正负极的一端与电路板30相连接；
第二电连接器50，其将电芯20正负极的另一端与电路板30相连接；
电动工具用电的放电接口60a，其配置于电路板30，并包括至少一接口，所述接口适于与外部的用电设备电连接，使得来自电芯的电力可以通过该电动工具用电的放电接口60a提供给电动工具用电设备；
第一连接件70，其适于与第一用电设备闩锁连接，并靠近电动工具用电的放电接口60a；
第二连接件80，其适于与第二用电设备闩锁连接，并远离电动工具用电的放电接口60a；
当第一连接件70对应沿其第一线性路径段L1与第一用电设备闩锁连接或解锁脱离时，第二连接件80于第一线性路径段L1之外；
如此，第二连接件80必然与第一连接件70不干涉，无交互，不影响电池包100与清洁设备200a匹配使用。
其中，上述第一连接件70和第二连接件80优选位于相同平面10d。
此外，还值得一提的是：
电路板30间隔支撑于支撑骨架上，电路板与支撑骨架之间最小间距不大于2mm；通过间距H的设置，有效保证电路板30与电芯20之间具有一定的散热效果和电子安装空间。
并且，电路板30宽度为Y，电芯20直径为D，宽度Y为宽度D的95％或更小；本实施例中，电路板30宽度Y为20mm，电芯20直径D为21mm。
此外，电芯20长度为L3，电池包100的长度为L4，L4为L3的1.3倍或更小；电芯直径为D，电池包高度为M，M为D的1.8倍或更小；在具体实施例中，电芯20长度为70mm，电池包100的长度为82mm；电芯20直径为21mm，电池包100高度为36mm；采用上述结构设置，能够有效保证本实施例的电池包的结构小巧，作为移动电源使用时，便于携带，同时能够适用于各种小型电动工具。
最后应说明的是：以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述实施例所记载的技术 方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明实施例技术方案的范围。
