Abstract

A wiring terminal and a motor including the wiring terminal are provided. The wiring terminal includes: a mounting subassembly adapted to embed in a slot of an end insulator of a motor, a connection subassembly configured to support a wire stock having a lead wire, and a winding subassembly configure to receive an enameled wire wound on the winding subassembly. The connection subassembly and the winding subassembly are disposed on the top surface of the mounting subassembly. The lead wire of the wire stock is electrically connected to the enameled wire wound on the winding subassembly.

First claim

The invention claimed is:

1. A wiring terminal, comprising:
a mounting subassembly, the mounting subassembly comprising a mounting sheet having a first end and a second end opposite to each other; the first end of the mounting sheet being adapted to be inserted in a slot of an end insulator of a motor;
a supporting subassembly, the supporting subassembly comprising a supporting sheet that is adapted to support a wire stock having a lead wire; and
a winding subassembly, the winding subassembly comprising a winding post that is adapted to receive an enameled wire wound on the winding post;
wherein:
the supporting subassembly and the winding subassembly are disposed on the second end of the mounting subassembly; and
the lead wire of the wire stock is adapted to be electrically connected to the enameled wire wound on the winding subassembly;
the supporting sheet protrudes from the second end of the mounting sheet, and extends away from the winding post and substantially along a transversal direction that is perpendicular to the mounting sheet;
the winding post protrudes from the second end of the mounting sheet, and extends substantially along a longitudinal direction that is parallel to the mounting sheet and that extends from the first end of the mounting sheet toward the second end of the mounting sheet;
a free end of the supporting sheet extends toward the winding post and substantially along the longitudinal direction; and
a notch is confined by the supporting sheet and the winding post for securing the lead wire of the wire stock, wherein the notch has a u-shape cross section and extends along a direction that is substantially perpendicular to the longitudinal direction.

2. The wiring terminal of claim 1 , wherein the supporting sheet is two in number; the two supporting sheets respectively protrude from two edges of the second end of the mounting subassembly in the same direction; and the winding post is located between the two supporting sheets, and extends in a direction away from the two supporting sheets.

3. The wiring terminal of claim 2 , wherein a lower part of the winding post extends toward the two supporting sheets and is adapted to squeeze and fix the wire stock in the notch.

4. The wiring terminal of claim 3 , wherein two lug bosses protrude from two sides of a free end of the winding post, respectively; and the winding post is T-shaped.

5. The wiring terminal of claim 3 , wherein one surface of the mounting sheet comprises a convex part, and the other surface of the mounting sheet is provided with a concave part; and the convex part is corresponding to the concave part.

6. The wiring terminal of claim 2 , wherein two lug bosses protrude from two sides of a free end of the winding post, respectively; and the winding post is T-shaped.

7. The wiring terminal of claim 2 , wherein one surface of the mounting sheet comprises a convex part, and the other surface of the mounting sheet is provided with a concave part; and the convex part is corresponding to the concave part.

8. The wiring terminal of claim 1 , wherein two lug bosses protrude from two sides of a free end of the winding post, respectively; and the winding post is T-shaped.

9. The wiring terminal of claim 1 , wherein one surface of the mounting sheet comprises a convex part, and the other surface of the mounting sheet is provided with a concave part; and the convex part is corresponding to the concave part.

10. A motor, comprising a wiring terminal of claim 1 .

11. The motor of claim 10 , comprising:
a rotary shaft;
a plastic-packaged stator, the plastic-packaged stator comprising a sleeve base, a stator core, an end insulator, coil windings, and a plastic-packaged body; and
an external rotor comprising a chamber;
wherein
the plastic-packaged stator is disposed in the chamber of the external rotor;
the end insulator is disposed on one end surface of the stator core; the coil windings are wound on the end insulator; the sleeve base is disposed in a shaft hole of the stator core; bearing housings are disposed on two ends of the sleeve base; a bearing is disposed in each bearing housing; the rotary shaft is disposed in the sleeve base, and two ends of the rotary shaft are supported by the bearing; the sleeve base, the stator core, the end insulator, and the coil windings are disposed in the plastic-packaged body; one end of the rotary shaft protrudes out from the sleeve base and is connected to the external rotor; and
the end insulator is provided with a slot, and the wiring terminal is embedded in the slot.

12. The motor of claim 10 , wherein the supporting sheet is two in number; the two supporting sheets respectively protrude from two edges of the second end of the mounting subassembly in the same direction; and the winding post is located between the two supporting sheets, and extends in a direction away from the two supporting sheets.

13. The motor of claim 12 , wherein a lower part of the winding post extends toward the two supporting sheets and is adapted to squeeze and fix the wire stock in the u-shaped notch.

14. The wiring terminal of claim 13 , wherein two lug bosses protrude from two sides of a free end of the winding post, respectively; and the winding post is T-shaped.
