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.

The utility model provides a silicon carbide ceramic radiating fin which comprises a radiating plate, the top of the radiating plate is concaved inwards to form a heat conduction silicone grease cavity, a threaded column is vertically arranged at the bottom of the heat conduction silicone grease cavity, a connecting plate matched with the heat conduction silicone grease cavity is arranged on the threaded column in a sleeved mode, a threaded cylinder is rotationally arranged at the top of the connecting plate, and the threaded cylinder is connected with the heat conduction silicone grease cavity in a sleeved mode. The threaded cylinder is arranged on the threaded column in a sleeving mode and is in threaded connection with the threaded column, and a plurality of cooling fin bodies are arranged at the top of the connecting plate; the heat-conducting silicone grease is flatly laid in the heat-conducting silicone grease cavity, heat absorbed by the heat-conducting silicone grease is dissipated through the cooling fin bodies arranged on the connecting plate, the situation that the heat-conducting silicone grease directly makes contact with the electronic element and overflows to pins welded to the electronic element can be avoided, and poor connection of the electronic element is prevented.
