The overcurrent capability of the conductive terminal is determined by its own resistance. Generally speaking, the smaller the resistance, the greater the overcurrent capability. The size of the resistance is not only related to the conductivity of the conductive terminal material itself, but also related to the volume of the conductive terminal. In the case of the same length, the larger the cross-sectional area of the conductive terminal (the wider and higher the conductive terminal), the higher the resistance. Smaller, the greater the overcurrent capability.

Please refer to Figure 10. In order to meet the positive and negative insertion function of the connector female seat, a total of 24 symmetrical conductive terminals are arranged on the upper, lower, left and right sides, resulting in crowding between the conductive terminals, especially the power terminals (A4, A4, A9, B4, B9), the width and thickness of the power terminals are limited due to factors such as other terminals on the upper and lower sides, as well as the manufacturing process, so the overcurrent capability is limited; even if the conductive terminals are improved The material itself, using the high-conductivity copper material currently on the market to make the conductive terminals, cannot meet the high current overload of more than 10A, which further limits the improvement of the charging power.
