Abstract

A terminal includes a top wall, a side wall, and a curved part connected between the top wall and the side wall. A notch is formed on the curved part. The notch reduces a bending force for forming the curved part and prevent cracks from being generated in the curved part during forming the curved part.

First claim

What is claimed is:

1. A terminal, comprising:
a top wall;
a side wall; and
a curved part connected between the top wall and the side wall, a notch is formed on the curved part, and the notch is only located on the curved part.

2. The terminal of claim 1 , wherein the notch reduces a bending force for forming the curved part and prevent cracks from being generated in the curved part during forming the curved part.

3. The terminal of claim 1 , wherein the notch is one of a plurality of notches in the curved part, the notches are spaced from each other and extend along a length direction of the terminal.

4. The terminal of claim 3 , wherein a sum of a plurality of extension lengths of the notches along the length direction is greater than or equal to one-fourth of an extension length of the curved part along the length direction.

5. The terminal of claim 4 , wherein the sum of the plurality of extension lengths of the notches along the length direction is less than or equal to three-quarters of the extension length of the curved part along the length direction.

6. The terminal of claim 4 , wherein the extension lengths of the notches are the same as one another.

7. The terminal of claim 4 , wherein the extension lengths of the notches are different from one another.

8. The terminal of claim 1 , wherein the notch is the only notch on the curved part.

9. The terminal of claim 8 , wherein an extension length of the notch along a length direction of the terminal is greater than or equal to one-fourth of an extension length of the curved part along the length direction.

10. The terminal of claim 9 , wherein the extension length of the notch along the length direction is less than or equal to three-quarters of the extension length of the curved part along the length direction.

11. The terminal of claim 1 , wherein the side wall includes a first side wall and a second side wall at opposite sides of the top wall in a width direction, the curved part has a first curved part connected between the top wall and the first side wall and a second curved part connected between the top wall and the second side wall.

12. The terminal of claim 11 , wherein the notch is one of a plurality of notches formed on at least one of the first curved part and the second curved part.

13. The terminal of claim 11 , wherein the notch is a single notch formed on each of the first curved part and the second curved part.

14. The terminal of claim 11 , further comprising an elastic latch connected to the first side wall configured to be locked to a housing of a connector.

15. The terminal of claim 11 , further comprising an elastic arm connected to the second side wall and facing the top wall, the elastic arm electrically contacts a mating terminal inserted between the elastic arm and the top wall.

16. The terminal of claim 15 , wherein the top wall has a first electrical contact projecting toward the elastic arm.

17. The terminal of claim 16 , wherein the elastic arm has a second electrical contact projecting toward the first electrical contact, the first electrical contact and the second electrical contact simultaneously contact an upper side and a lower side of the mating terminal.

18. The terminal of claim 1 , further comprising a wire connection part connected to the top wall and the side wall.

19. The terminal of claim 18 , wherein the wire connection part has a pair of first wings crimped on a conductor core of a wire and a pair of second wings crimped on an outer layer of the wire.

20. The terminal of claim 1 , wherein the terminal is formed by stamping a single terminal material plate.

21. A connector, comprising:
a housing; and
a terminal disposed in the housing, the terminal including a top wall, a side wall, and a curved part connected between the top wall and the side wall, a notch is formed on the curved part, and the notch is only located on the curved part.
