Abstract
A terminal-wire bonding method includes: arranging a first core at a second end of a first terminal-wire having a first terminal connected with the first core exposed from an insulating sheath at a first end, onto a side of an anvil and a second core at a second end of a second terminal-wire having a second terminal connected with the second core exposed, at a first end, from an insulating sheath longer than the insulating sheath of the first terminal-wire, onto a side of a horn; and bonding the first core at the second end and the second core at the second end together by ultrasonic bonding between the horn and the anvil.
Claims7
A terminal-wire bonding method with a first terminal-wire and a second terminal-wire, the first terminal-wire having a first terminal connected with a first core exposed from an insulating sheath at a first end, the first core being exposed from the insulating sheath at a second end of the first terminal-wire, the second terminal-wire having a second terminal connected with a second core exposed, at a first end, from an insulating sheath longer than the insulating sheath of the first terminal-wire, the second core being exposed from the insulating sheath longer than the insulating sheath of the first terminal-wire, at a second end of the second terminal-wire, the terminal-wire bonding method comprising:
- arranging the second core at the second end onto a side of a horn for ultrasonic bonding and the first core at the second end onto a side of an anvil for ultrasonic bonding;
- and
- bonding the first core at the second end and the second core at the second end together by ultrasonic bonding between the horn and the anvil.
A bonded terminal-wire comprising:
- a first terminal-wire having a first terminal connected with a first core including a plurality of strands exposed from an insulating sheath at a first end, the first core being exposed from the insulating sheath at a second end of the first terminal-wire;
- and
- a second terminal-wire having a second terminal connected with a second core including a plurality of strands exposed, at a first end, from an insulating sheath longer than the insulating sheath of the first terminal-wire, the plurality of strands each being identical in thickness to each strand of the first core, the second core being exposed from the insulating sheath longer than the insulating sheath of the first terminal-wire, at a second end of the second terminal-wire, wherein
- the first core at the second end and the second core at the second end are bonded together by ultrasonic bonding between a horn and an anvil for ultrasonic bonding with the second core at the second end arranged on a side of the horn and the first core at the second end arranged on a side of the anvil, and
- the plurality of strands of the second core at the second end on the side of the horn is bonded with collapse stronger than collapse of the plurality of strands of the first core at the second end on the side of the anvil.
