Abstract
An electrical connection includes an electrically conductive first contact member, an electrically conductive second contact member, an interface, and an attachment. The first contact member includes a first contact surface for passing current. The second contact member includes a second contact surface for passing current that directly contacts the first contact surface. The interface includes one of a cold weld and a fused section that physically joins the first contact member and the second contact member, and that forms a primary conductive path between the first contact member and the second contact member. The interface is formed by ultrasonic vibration of the first contact surface relative to the second contact surface. The attachment is separate from the interface and mechanically joins the first contact member and the second contact member. A method for forming the electrical method is also provided.
