Electric wire connection structure and connection method
A connection structure for an electric wire includes an electric wire that has a conductor and an outer sheath covering the conductor; a bonding member that is made of a conductive metal material and is attached to the electric wire and; and a busbar that is made of a conductive metal material and on which the bonding member is overlapped and ultrasonically bonded with the conductor interposed between the busbar and the bonding member. The bonding member includes a crimping portion for crimping and fixing the electric wire.
1. A connection structure for an electric wire, the connection structure comprising:
an electric wire that has a conductor and an outer sheath covering the conductor;
a bonding member that is made of a conductive metal material and is attached to the electric wire; and
a busbar that is made of a conductive metal material and on which the bonding member is overlapped and ultrasonically bonded with the conductor interposed between the busbar and the bonding member,
wherein the bonding member includes a crimping portion that crimps and fixes the electric wire.
2. The connection structure for an electric wire according to claim 1 ,
wherein the bonding member is made of copper or a copper alloy.
3. The connection structure for an electric wire according to claim 1 ,
wherein the bonding member is made of aluminum or an aluminum alloy.
4. A connection method of an electric wire, the connection method comprising:
an electric wire fixing step of crimping and fixing a crimping portion provided on a bonding member made of a conductive metal material to an electric wire exposing a conductor from an outer sheath; and
a bonding step of overlapping and ultrasonically bonding the bonding member to a busbar made of a conductive metal material via the conductor.
