Abstract

An electrical terminal is disclosed. The electrical terminal has a first contact made of a first metal and a coupling member made of a metal fixed to the first contact. The coupling member has a cantilever extending along the first contact with a free end extending toward the first contact. The cantilever presses a second contact made of the first metal against the first contact.

First claim

What is claimed is:

1. An electrical terminal, comprising:
a first contact made of a first metal; and
a coupling member made of a second metal fixed to the first contact, the coupling member having a cantilever with a free end extending toward the first contact, the cantilever pressing a second contact made of the first metal and fixed to a mating electrical terminal against the first contact, the second contact disposed between the cantilever and the first contact.

2. The electrical terminal of claim 1 , wherein the mating electrical terminal is formed identically to the electrical terminal.

3. The electrical terminal of claim 1 , wherein the coupling member is fixed to the first contact by spot welding or swaging.

4. The electrical terminal of claim 1 , wherein the first contact has an elongated rectangular shape or a rod-like shape.

5. The electrical terminal of claim 4 , wherein the first contact has a projection extending from a side face of the first contact.

6. The electrical terminal of claim 4 , wherein the first contact has a catch disposed approximately centrally on a side of the first contact.

7. The electrical terminal of claim 6 , wherein the coupling member has a latch disposed approximately centrally on a side of the coupling member engaging the catch.

8. The electrical terminal of claim 1 , wherein the coupling member has a crimping portion crimped to press the first contact against an electrical wire made of the first metal.

9. The electrical terminal of claim 8 , wherein the coupling member is fixed to the first contact independently of crimping at the crimping portion.

10. The electrical terminal of claim 9 , wherein the coupling member has a sheath crimping portion disposed on a rear end of the coupling member.

11. The electrical terminal of claim 10 , wherein the coupling member has a core crimping portion disposed adjacent the sheath crimping portion.

12. The electrical terminal of claim 11 , wherein the sheath crimping portion is crimped to a sheath of the electrical wire.

13. The electrical terminal of claim 12 , wherein the core crimping portion is crimped to a core of the electrical wire.

14. The electrical terminal of claim 1 , wherein a front end of the first contact extends from a front end of the coupling member.

15. The electrical terminal of claim 1 , wherein a front end of the first contact is aligned with a front end of the coupling member in a direction perpendicular to a longitudinal direction of the electrical terminal.

16. The electrical terminal of claim 1 , wherein the first metal is alumel or chromel.

17. The electrical terminal of claim 16 , wherein the second metal is a copper alloy.

18. The electrical terminal of claim 1 , wherein the cantilever extends from a top wall of the coupling member and the first contact is disposed along an opposite bottom wall of the coupling member.

19. The electrical terminal of claim 18 , wherein the cantilever directly abuts the second contact.
