Tool and method of using the same for inserting leads through resilient grommets

Abstract

Abstract A TOOL AND METHOD OF USING THE SAME FOR FACILITATING THE OPERATION OF PASSING ELECTRICAL LEADS THROUGH RESILIENT GROMMETS WHICH ARE USED TO CONDUCT THE LEADS IN SOUNDTIGHT RELATIONSHIP THROUGH THE WALL OF A SOUND ATTENUATING HELMET EARCUP. THE TOOL IS AN ELONGATED TAPERED BODY HAVING AN AXIAL BORE EXTENDING FROM ITS LARGER END TO A POINT INTERMEDIATE THE ENDS OF THE BODY, AT WHICH POINT A SLANTED WALL LEADS OUTWARDLY TO AN OPENING IN THE SIDE OF THE BODY. IN USE OF THE DEVICE, THE GROMMET IS SLID OVER THE BODY FROM ITS SMALLER END TO A POINT BEYOND THE SIDE WALL OPENING. THE LEADS ARE THEN INSERTED INTO THE BORE UNTIL THE PLUGS ON THE ENDS OF THE LEAD ARE GUIDED OUT THROUGH THE SIDE OPENING BY THE SLANTED WALL. THE GROMMET IS THEN SLIPPED OFF THE ENLARGED END OF THE BODY AND ONTO THE LEADS. A REMOVABLE PIN EXTENDING ACROSS THE LONGITUDINAL AXIS OF THE BODY MAY BE EMPLOYED TO FACILITATE THE OPERATION JUST DESCRIBED. THE BODY MAY BE LUBRICATED TO ASSIST IN SLIDING THE GROMMET THEREON. AFTER THE GROMMET HAS BEEN SLIPPED OFF THE BODY ONTO THE LEADS, THE LEADS ARE PASSED THROUGH THE CUP WALL OPENING AND THE GROMMET IS PUSHED INTO THE OPENING TO COMPLETE THE ASSEMBLY.
