Battery pack connector for connection to external device

The present invention relates to a battery pack connector structure to be connected to an external device, and more particularly, to a battery pack connector structure configured such that a negative (-) pin of a battery pack connector extends to protrude farther than a positive (+) pin of the battery pack connector, and thus, when the battery pack connector is connected to an external device, the negative (-) pin of the battery pack connector protrudes farther than the positive (+) pin of the battery pack connector. The negative (-) pin is electrically connected to a connector of an external device, and then the positive (+) pin is electrically connected to a connector of an external device. 本发明涉及一种要连接至外部设备的电池组连接器结构，并且更具体地，涉及一种电池组连接器结构，其被配置成使得电池组连接器的负(-)引脚延伸为比电池组连接器的正(+)引脚突出得更远，并且因此当电池组连接器连接至外部设备时，负(-)引脚电连接至外部设备的连接器，随后正(+)引脚电连接至外部设备的连接器。
