Abstract: A first electrical insulation substrate having a pin and a second electrical insulation substrate having a hole formed therethrough for receiving the pin is provided. The pin is designed to control and limit the flow of the pin material to an upper portion of the pin during a cold forming process to avoid cracking the pin. This is accomplished by making a lower portion of the pin resistant to flow and the upper portion of the pin susceptible to flow. The lower portion of the pin may have a greater cross sectional area than the upper portion thus making the lower portion resistant to flow and the upper portion of the pin susceptible to flow.

Abstract: The invention includes an electrical distribution center for including a two-piece main insulation assembly, Stamped male blade or tuning fork terminals are press-fit between the two-piece main insulation assembly, The upper half of the two-piece insulation assembly has a top surface including a plurality of terminal stations and guide stations that are raised and separated from each other so as to provide a network of wire channels that communicate with wire passages, The terminal stations have terminal slots that extend through the upper half of the main insulation assembly to intersect the wire passages, The bottom surface of the lower half of the two-piece insulation assembly is configured in a similar fashion as the top base of the upper portion of the two-piece insulation assembly,
