The utility model discloses a connector with external strong cooling structure. The connector includes: shell, a plurality of jack parts, a plurality of cables and at least one external
air cooling part, the shell includes a plurality of
high heat conduction fixed wire ends, and a plurality of protruding cooling fins are integrally arranged on the outer wall of each fixed wire end, the jack part is fixedly sleeved with the front end of the shell and the rear end is inserted into the fixed wire end, the cable is fixedly sleeved with the rear end of the shell and is inserted into the fixed wire end to connect the jack part, the external
air cooling part is fixedly connected with one side of the fixed wire end, the air suction port of the external
air cooling part is opposite to each cooling fin, the cooling fin conducts the heat of the connecting heat source to the outer end of the cooling fin, the external cooling part makes the
airflow continuously flow through the surface of the cooling fin and takes away the heat, and the connector is at the appropriate
working temperature. The utility model has the effects of simple structure, good heat dissipation, improved current-
carrying capacity and reduced temperature rise, more advantageous battery size, capacity and endurance, and good safety.
