Abstract
A terminal for connecting a fine magnet wire to a larger wire with relatively thick insulation. The terminal has a barrel at one end section thereof with serrations extending substantially circumferentially around the inner surface thereof. At the other end of said terminal there is a second barrel with tangs extending inwardly therein. The fine magnet wire is laid within the end of the barrel containing the serrations. The large wire with the heavy insulation is laid within both sections of said barrel including the portion containing the tangs and the portion containing the serrations. Crimping of both barrels in the terminal causes the heavy insulation on the large wire to force the magnet wire into the barrel serrations, thereby elongating the magnet wire and breaking the shellac or fine plastic insulation thereon so that the magnet wire makes electrical contact with the barrel. Because of the relatively soft and resilient nature of the heavy insulation on the large wire the forces on the magnet wire are distributed along the magnet wire so that breakage or weakening of the magnet wire is minimized while at the same time insuring electrical contact between the magnet wire and t…
