Abstract
Provided are an electronic component, a lead part connection structure, and a lead part connection method which can reduce damage of a lead part and improve joint strength. In this lead part connection structure, a lead part (3) made of a conductor and a conductive wire (5) made of a plurality of core wires (52) are connected to each other through welding, wherein the lead part (3) and the conductive wire (5) are connected to each other through welding in a condition in which the lead part (3) is fitted into the plurality of core wires (52) of the conductive wire (5). In the conductive wire (5), the core wires (52) are not integrated with each other in advance through welding.
Claims11
A lead part connection structure, connecting a lead part formed by a conductor and a conductive wire formed by a plurality of core wires by welding,
- wherein the lead part and the conductive wire are connected by welding in a state in which the lead part is entered into the core wires of the conductive wire,
- wherein a deformation of a thickness dimension of a cross-section of the lead part due to welding between the lead part and the conductive wire is 50% or less.
A lead part connection method adapted for a resistance welding apparatus, wherein the resistance welding apparatus includes a lower electrode and an upper electrode, a mounting space of a material to be welded is formed on a side of the lower electrode, and the material to be welded is a lead part formed by a conductor and a conductive wire formed from a plurality of core wires, the core wires not being integrated by welding in advance, the lead part connection method comprising:
- in a state in which the conductive wire and the lead part on or in the conductive wire are mounted in the mounting space, pressing and heating only the lead part and the conductive wire from above and below by using the lower electrode and the upper electrode so as to bond the lead part and the conductive wire through welding.
