ABSTRACT:
A press-fit feed-through device has one or more sets of laterally protruding and symmetrically distributed teeth that are laterally aligned and cut through the material of a bulkhead as the feed-through is inserted into a bulkhead opening. Lateral grooves disposed immediately inboard of each set of teeth receive the bulkhead material cut by the respective set of teeth. In feed-through devices having more than one set of teeth, the additional sets of teeth are located successively outboard of, and in axial alignment with, the first set of teeth, and cut successively deeper into the bulkhead as the feed-through is inserted into the opening.
