Abstract
Abstract A TWO PART DIE CRIMPS A WIRE CONDUCTOR TO A CONNECTOR BARREL. THE BARREL IS COVERED BY A PLASTIC INSULATING SLEEVE THAT FORMS A SHROUD FOR A SHORT LENGTH OF THE CONDUCTOR EXTENDING OUT OF THE BARREL. ONE PART OF DIE CRIMPS THE BARREL TO THE CONDUCTOR AND IS FORMED WITH A CHANNEL INTO WHICH THE PLASTIC OF THE SLEEVE FLOWS DURING CRIMPING TO FORM A RIDGE THAT LIMITS THE EXTRUSIONS OF THE SLEEVE SO AS TO PRESERVE ITS INSULATING VALVE. THE OTHER PART OF THE DIE PRESSES THE SHROUD PORTION OF THE SLEEVE AGAINST THE CONDUCTOR. A STOP DETERMINES THE DEGREE OF MOVEMENT BETWEEN THE TWO PARTS OF THE DIE AND THEREFORE THE PRESSURE AGAINST THE SHROUD PORTION OF THE SLEEVE.
