1results about How to "Poor connection" patented technology

This utility model relates to the field of portable power bank technology, specifically to a portable power bank. The portable power bank includes a main shell, a charging cable, and a circuit board. The main shell includes a bottom shell and a side shell surrounding the edge of the bottom shell. The circuit board is installed in the main shell. The side shell has a cable entry opening, through which the charging cable's connecting end passes from the outside of the side shell into the main shell and electrically connects to the circuit board. On the inside of the side shell, a limiting sleeve is fixedly fitted onto the charging cable's connecting end. The limiting sleeve and the inside of the cable entry opening form a barrier, preventing the charging cable's connecting end from being pulled outwards from the side shell. The limiting sleeve abuts against the inside of the cable entry opening, preventing the charging cable's connecting end from being pulled outwards from the side shell. This prevents external force from pulling on the electrical connection point between the charging cable and the circuit board, avoiding poor electrical connection. This utility model uses a limiting sleeve to limit the charging cable's connecting end, resulting in fewer parts, simpler assembly, no need for additional injection molding, convenient processing, and a lower defect rate.
