Abstract
A connector includes an aluminum cable, a copper terminal, and an aluminum junction part having a first end configured to join to the aluminum cable and a second end configured to join to the copper terminal. By providing the junction part in aluminum, the connector establishes a metallurgically compatible interface and enables efficient electrical conduction between the aluminum cable and the copper terminal.
Claims13
A connector, comprising:
- an aluminum cable;
- a copper terminal;
- and
- a junction part made of aluminum, wherein the junction part comprises a first end able to be joined to the aluminum cable and a second end able to be joined to the copper terminal.
A method of manufacturing a connector having an aluminum cable, a copper terminal, and a junction part made of aluminum, wherein the junction part comprises a first end able to be joined to the aluminum cable and a second end able to be joined to the copper terminal, wherein the second end comprises a first face perpendicular to a connector's axis, and the copper terminal comprises a corresponding second face perpendicular to the connector's axis, facing the first face, and one of the faces among the first face of the second end and the second face of the copper terminal comprises an outer chamfer and the first face comprises a corresponding inner chamfer, shaped to cover and receive the outer chamfer, the method comprising:
- inserting the outer chamfer into the inner chamfer;
- joining the second end of the junction part with the copper terminal by cold forging, so as to interpenetrate both chamfers;
- and
- joining the first end with the aluminum cable by electromagnetic pulse technology welding.
