IGBT PTC CONNECTING STRUCTURE OF PTC ROD AND BUSBAR

摘要

The present invention relates to a connection structure of a PTC rod and a bus bar for heat exchange of an IGBT that can stably connect electrodes of a PTC rod to a bus bar without a crimping and soldering process using a separate brass piece. The present invention is a connection between the PTC rod and the bus bar for heat exchange of the IGBT of the PTC heater for heating the air for heating the vehicle, the bus bar is bent in a '∩' shape in the connecting groove of the guide member, the connection As the electrode of the PTC rod is inserted into the groove, the busbar and the electrode of the PTC rod come into surface contact.
