  • the connecting device can be easily inserted into the housing and again easily removed from the housing.
  • the tabs offer the advantage that the supply lines of the connector can be fixed by compressing the tabs when removing the sealant molding from the housing.
  • a part body has a nose, preferably a latching nose, and the corresponding part body has an associated recess.
  • the partial bodies are mechanically fixed in addition to each other.
  • Another embodiment would be a non-detachable connection, in which the part bodies are connected by way of example by gluing.
  • the sealant molding has at least one stop edge, which is formed in each case for abutment against an associated abutment in the housing. This ensures a tight and permanent fit.
  • the leads When inserting the connector, the leads are inserted with connected contact means in the first recesses in one of the two body part.
  • the connector is inserted with slight pressure, so that the slats include the leads partially.
  • the last method step involves the assembly of the sealant molding with the housing.
  • the connecting device is inserted into the housing of the power semiconductor device.
  • the advantage of this method is that the connecting device can be quickly mounted according to the above method steps.
