## Abstract

A simple structure which improves reliability of connection and secures creeping and spatial distances for electrical insulation without increasing manufacturing cost is provided. Feed-through terminals whose diameters can be reduced are bonded to lands of a wiring substrate, and insertion terminals are bonded to core wires of lead wires. The insertion terminals of the lead wires are arranged in the feed-through terminals bonded to the lands. In a state where the feed-through terminals are swaged and the insertion terminals of the lead wires are pressure-bonded, the insertion terminals of the lead wires are bonded to the feed-through terminals.

## Claims

### Claim 1

A power line connecting structure of a stator which is a structure which connects a lead wire as a power line to a wiring substrate which the stator comprises, wherein
a feed-through terminal whose diameter can be reduced is bonded to a land of the wiring substrate, and a core wire of the lead wire is arranged in the feed-through terminal bonded to the land, and
in a state where the feed-through terminal is swaged and a coated portion and the core wire of the lead wire are pressure-bonded, the core wire of the lead wire is bonded to the feed-through terminal.

### Claim 2

A power line connecting structure of a stator which is a structure which connects a lead wire as a power line to a wiring substrate which the stator comprises, wherein
a feed-through terminal is bonded to a land of the wiring substrate, and an insertion terminal is swaged such that a coated portion and a core wire of the lead wire are pressure-bonded to bond the insertion terminal to the core wire of the lead wire,
the insertion terminal of the lead wire is arranged in the feed-through terminal bonded to the land, and
the insertion terminal of the lead wire is bonded to the feed-through terminal.

### Claim 3 (depends on 1)

The power line connecting structure of the stator according to claim 1, wherein the feed-through terminal is a U-shaped terminal whose at least one side is opened.
