Abstract

Disclosed herein is a motor terminal including a body including a connection terminal, a rear end portion allowing the connection terminal to be connected to a busbar terminal, and a front end portion allowing the connection terminal to be connected to a terminal of another component, and a pair of hook portions formed on both sides of the body, respectively, so as to be symmetrical on the basis of a criteria line passing a center of the body in a width direction, and configured so as to be open to be further away from each other as directed toward the front end portion from the rear end portion and to be elastically deformable. Consequently, it may be possible to prevent damage to the terminal and more effectively prevent the terminal from being inclined or biased in an initial state in which the terminal is inserted into a terminal hole.

First claim

What is claimed is:

1. A motor terminal comprising:
a body comprising a connection terminal, a rear end portion allowing the connection terminal to be connected to a busbar terminal, and a front end portion allowing the connection terminal to be connected to a terminal of another component; and
a pair of hook portions formed on both sides of the body, respectively, and configured so as to be open to be further away from each other as directed toward the front end portion from the rear end portion and to be elastically deformable,
wherein the body comprises a first part in which one of the pair of hook portions is disposed and a second part in which the other of the hook portions is disposed, the second part being coupled to the first part,
wherein the first part comprises coupling protrusions disposed on front and back surfaces thereof, and the second part comprises coupling holes disposed on front and back surfaces thereof, the coupling protrusions being fitted into the coupling holes.

2. The motor terminal of claim 1 , wherein the body comprises a pair of centering ribs disposed on both sides of the body so as to be symmetrical on the basis of a center line and protrude in a width direction.

3. The motor terminal of claim 2 , wherein each of the centering ribs comprises a first cutting portion disposed by cutting a corner formed by a tip surface of the centering rib and a side surface of the centering rib.

4. The motor terminal of claim 1 , wherein the rear end portion comprises a pair of second cutting portions disposed so as to be symmetrical on the basis of a criteria line and disposed by cutting a corner formed by an end surface of the rear end portion and both side surfaces of the rear end portion.

5. The motor terminal of claim 1 , wherein the pair of hook portions are symmetrical on the basis of a criteria line passing a center of the body in a width direction.

6. A motor terminal assembly comprising:
a bracket formed with a terminal hole; and
a terminal comprising a body which comprises a connection terminal, a rear end portion allowing the connection terminal to be connected to a busbar terminal, and a front end portion allowing the connection terminal to be connected to a terminal of another component, and a pair of hook portions formed on both sides of the body, respectively, and configured so as to be open to be further away from each other as directed toward the front end portion from the rear end portion and to be elastically deformable,
wherein the front end portion has a larger horizontal cross-section than the terminal hole so as to be caught by the terminal hole, and the rear end portion has a smaller horizontal cross-section than the terminal hole so as to move in the terminal hole,
wherein the body comprises a first part in which one of the pair of hook portions is disposed and a second part in which the other of the hook portions is disposed, the second part being coupled to the first part,
wherein the first part comprises coupling protrusions disposed on front and back surfaces thereof, and the second part comprises coupling holes disposed on front and back surfaces thereof, the coupling protrusions being fitted into the coupling holes.

7. A method of assembling a motor using the motor terminal assembly of claim 6 , the method comprising:
a) assembling the bracket to a motor housing in such a manner that the connection terminal connected to a cable passes through the terminal hole;
b) assembling the terminal by coupling the body to the connection terminal; and
c) inserting the assembled terminal into the terminal hole.

8. The motor terminal of claim 1 , wherein each of the hook portions comprises a first fixed end portion which extends in a first direction from an end portion thereof to support an inside surface of a bracket around a terminal hole, and a second fixed end portion which extends in a perpendicular direction to the first direction from the end portion to support an inner wall of the terminal hole.

9. The motor terminal of claim 5 , wherein each of the hook portions comprises third cutting portions disposed by cutting a corner formed by an end surfaces and outside surfaces of the hook portion.

10. The method of claim 7 , wherein:
the body comprises a first part in which one of the pair of hook portions is formed and a second part in which the other of the hook portions is formed, the second part being coupled to the first part; and
in the b) assembling the terminal, the first and second parts are coupled to each other such that the body is coupled to the connection terminal.

11. The motor terminal assembly of claim 6 , wherein the bracket comprises fixed ribs which protrude from an inside surface around the terminal hole to restrict movement of the pair of hook portions.

12. The motor terminal assembly of claim 6 , wherein each of the hook portions comprises a first fixed end portion which extends in a first direction from an end portion thereof to support an inside surface of the bracket around the terminal hole, and a second fixed end portion which extends in a perpendicular direction from the first direction to the end portion to support an inner wall of the terminal hole.

13. The motor terminal assembly of claim 6 , wherein the pair of hook portions are symmetrical on the basis of a criteria line passing a center of the body in a width direction.
