AmP is actually a terminal manufacturer so pervalent that it is almost like kleannex. The quick disconnect being a std go to these days. 32 years ago when I worked for TRW Resistive Products Division we used Amp terminals to crimp the wire leads to the power wirewound resistors. They were a brass terminal that would cut the wire to length after the wirewound resistor core material, a fiberglass braided cord, was fed into the termination machine. It would cut the core material to length and crimp the wire leads to the resistive wire wound around the fiberglass braid. Using Amp's terminals that were joined together with thin bridge of material left between each terminal that was sheered from its adjacent terminal in the strip fed terminals. The dies would cut the core to a setup length that was tuned by the line mechanics to get the resistors within tolerances (aiming towards the specified value of course). The wire for the leads cut and fed into their positions on the terminal segments held in the die, core dropped in place, then the die would crimp the terminals on both ends tight before ejecting the completed core resistor into the receptical for the next step in the manufacturing process wher the resistor was placed in its ceramic shell and filled with a thermally conductive material encapsulating the resistor into its final package.
Sorry for the segue, sidetrack... Amp make a ton of specialized and common terminals used in all kinds of electrical/ electronic connectors and terminals.
Amp also makes tubular pin and socket terminals as well...Our bike's stock bullet connectors are a type of connector making a physical locking connection by the terminals ( male and female) rather than a connector housing. The terminals in the connector blocks are often an Amp product as is the connector body. There are more makers than Amp but they are one of if not the largest out there worldwide.
