Patent ID: 7105961

Claim:
A lead terminal structure of a resolver comprising; a ring-shaped stator core in which a fixed magnetic pole having a plurality of fixed pole shoes is protruded in the direction of the center of a ring-shaped yoke member and a plurality of plate-like members are laminated; a lead-wire-fixed portion in which a stator winding wound around the fixed pole shoes of the stator core is connected to a lead wire; a stator-winding mounting board, on which a fixing pin for fixing the stator winding is arranged so as to stand thereon, provided in the lead-wire-fixed portion; and a lead-wire-fixing attachment, at the upper end of which at least one through-hole for fixing the lead wire is provided, arranged above the stator-winding mounting board, wherein the lead wire is connected to the stator-winding mounting board by way of the through-hole, the lead-wire-fixed portion is filled with a potting material, the lead-wire-fixing attachment is formed by a first attachment and a second attachment, the first attachment includes at least one first notch provided along a first contacting surface of the first attachment, the second attachment includes at least one second notch provided along a second contacting surface of the second attachment, each of the through-holes is formed by corresponding ones of the first notch and the second notch when the first contacting surface is in contact with the second contacting surface, and the first attachment and the second attachment are connected at corresponding ends thereof by a connection that allows for the first contacting surface of the first attachment and the second contacting surface of the second attachment to be moved toward each other to form the respective notches, and to be moved away from each other to open the respective notches, wherein the lead wire connected to the stator-winding mounting board does not touch a bottom portion of the lead-wire-fixed portion due to a protrusion with a through-hole formed at the bottom portion of the lead-wire-fixed portion.
