Patent ID: 6841921

Claim:
An ultrasonic horn assembly for transporting ultrasonic energy to an operating location to apply the ultrasonic energy to at least one article at the operating location, the horn assembly comprising: a first stack component having at least one transfer face; a second stack component having at least one transfer face adapted to engage the transfer face of the first stack component at an interface for transmitting ultrasonic energy from one of the first and second stack components to the other; a connector which connects the first stack component to the second stack component by applying opposing clamping forces originating at locations within the first and second stack components, which opposing clamping forces oppose each other across the interface, and which connector is free of directly engaging gripping connection to at least one of the first and second stack components along a segment of the connector passing through a plane defined by the interface; and wherein the segment of the connector which is free of directly engaging gripping connection constitutes between about 50% and about 75% of the overall length of the connector.
