Method for potting electrical devices
Abstract
Abstract METHOD FOR POTTING ELECTRICAL DEVICES IN WHICH A FRAME HAVING AN OPENING AND A THREE-DIMENSIONAL SPACER IS PLACED ON AN OPEN PORTION OF THE HOUSING. THE THREEDIMENSIONAL SPACER EXTENDS INTO SAID HOUSING AND HOT POTTING COMPOUND IS POURED INTO THE HOUSING THROUGH THE FRAME OPENING. UPON COOLING OF THE POTTING COMPOUND THE FRAME IS REMOVED LEAVING A VOID WHERE THE SPACER WAS LOCATED INTO WHICH THE POTTING COMPOUND CAN EXPAND UPON SUBSEQUENT HEATING. AN INSULATED LEAD WIRE OF THE ELECTRICAL DEVICE PASSES OUT THROUGH A HOUSING WALL ADJACENT WHICH THE SPACER IS LOCATED. THE SPACER COVERS A PORTION OF THE LEAD WIRE TO PREVENT THE HOT POTTING COMPOUND FROM COMING INTO DIRECT CONTACT WITH IT.
