Resolver external conductor fixing structure
View Patent ↗A resolver external conductor fixing structure which includes a connection body having a plurality of leads, and a terminal pin holding part formed on a portion of an insulation cover for an annular stator. The terminal pin holding part and the connection body are configured to detachably engage to allow the leads to be disconnected during assembly of a resolver and connected when assembly is complete.
1. A resolver external conductor fixing structure, comprising:
a ring-shaped stator having a first surface and a second surface;
an insulating cover including a first ring-shaped member integral with said first surface of said ring-shaped stator, and a second ring-shaped member integral with said second surface of said ring-shaped stator;
a connection body including a plurality of leads;
a terminal pin holding part integral with said insulating cover; and
a plurality of terminal pins disposed in said terminal pin holding part, each of said terminal pins having a coil connecting portion, a lead connecting portion which protrudes from said terminal pin holding part so as to be exposed, and a step portion adjoining said coil connecting portion and said leading connecting portion such that said coil connecting portion is spaced radially outward of said lead connecting portion, wherein
said coil connecting portion extends from said first surface of said ring-shaped stator in an axial direction, and said lead connecting portion extends toward said second surface of said ring-shaped stator in an opposite axial direction, and said connection body and said terminal pin holding part are configured to detachably engage to allow said plurality of leads to be connected with said lead connecting portions of said plurality of terminal pins.
2. The resolver external conductor fixing structure according to claim 1 , wherein each of said lead connecting portions includes an outer surface and an inner surface extending toward said second surface of said ring-shaped stator in the opposing axial direction, said outer and inner surfaces being exposed so as to be connectable with said plurality of leads.
3. The resolver external conductor fixing structure according to claim 1 , wherein each of said lead connecting portions has a flat plane shape.
4. The resolver external conductor fixing structure according to claim 1 , wherein said connection body comprises a plurality of lead guide holes formed therein, for guiding said plurality of leads.
5. The resolver external conductor fixing structure according to claim 1 , wherein said coil connecting portion is disposed in a first plane, and said lead connecting portion is disposed in a second plane which is parallel to said first plane.
