A full connector understanding requires several layers of information that are easy to confuse. Contact count is not the same as contact role. Physical arrangement is not the same as polarity. A title-level configuration is not the same as a drawing. In a battery pack connector context, the difference is especially important because the interface may sit near energy storage, power distribution, sensing, or control circuits. Even a simple-looking connector label may hide decisions about creepage distance, insulation, terminal size, mating sequence, contact plating, locking style, and strain relief. These items normally belong to the specification sheet, drawing package, or engineering communication, not to a short product title.
