Abstract

A terminal includes a terminal body and/or a first wing that may extend from the terminal body. The first wing that may have an end portion, a middle portion and/or a connecting portion. The inner surface of the end portion may be in contact with an inner surface of the middle portion. A terminal may include a second wing that may extend from the terminal body. An outer surface of the middle portion of the first wing may contact an outer surface of the middle portion of the second wing. A first wing and a second wing may be disposed on opposite sides of the terminal body. The second wing may include an end portion, a middle portion, and/or a connecting portion. A connecting portion of the first wing and a connecting portion of the second wing may both connect to the terminal body.

First claim

What is claimed is:

1. A terminal, comprising:
a terminal body, and
a first conductor wing extending from the terminal body, the first conductor wing including an end portion, a middle portion, and a connecting portion,
a first insulator wing extending from the terminal body, the first insulator wing including an end portion, a middle portion, and a connecting portion, and
wherein an inner surface of the end portion of the first conductor wing is in contact with an inner surface of the middle portion of the first conductor wing; an inner surface of the end portion of the first insulator wing is in contact with an inner surface of the middle portion of the first insulator wing; and the first conductor wing is offset from the first insulator wing in a longitudinal direction.

2. The terminal of claim 1 , including a second conductor wing extending from the terminal body.

3. The terminal of claim 2 , wherein an outer surface of the middle portion of the first conductor wing is in contact with an outer surface of the middle portion of the second conductor wing.

4. The terminal of claim 2 , wherein the first conductor wing and the second conductor wing are disposed on opposite sides of the terminal body.

5. The terminal of claim 2 , wherein the second conductor wing includes an end portion, a middle portion, and a connecting portion; and the connecting portion of the first conductor wing and the connecting portion of the second conductor wing are both connected to the terminal body.

6. The terminal of claim 2 , wherein the first conductor wing, the second conductor wing, and the terminal body form a substantially closed first channel.

7. The terminal of claim 2 , wherein the first conductor wing, the second conductor wing, and the terminal body are configured to retain at least a portion of a conductor; the first insulator wing, a second insulator wing, and the terminal body are configured to retain at least a portion of an insulator; and the insulator is connected to the conductor.

8. The terminal of claim 2 , including a second insulator wing.

9. The terminal of claim 8 , wherein the first conductor wing, the second conductor wing, and the terminal body form a substantially closed first channel; the first insulator wing, the second insulator wing, and the terminal body form a substantially closed second channel; and the substantially closed first channel and the substantially closed second channel both extend substantially along a longitudinal axis.

10. The terminal of claim 8 , wherein the connecting portion of the first conductor wing and the connecting portion of the second conductor wing are disposed apart at a first distance, a connecting portion of the first insulator wing and a connecting portion of the second insulator wing are disposed apart at a second distance, and the first distance is less than the second distance.

11. An electrical assembly comprising:
an electrical wire,
a terminal body, and
a plurality of wings including a first wing, and a second wing,
wherein the first wing includes a first bent portion, the second wing includes a second bent portion, the first wing and the second wing contact a bottom portion of the terminal body to form a channel, and at least one of the first bent portion and the second bent portion is crimped with the electrical wire.

12. The electrical assembly of claim 11 , wherein the electrical wire is a stranded conductor, and the stranded conductor substantially fills the channel.

13. The electrical assembly of claim 12 , wherein the first wing defines a first gap; the second wing defines a second gap; and no portion of the electrical wire is disposed within the first gap or the second gap.

14. The electrical assembly of claim 13 , wherein the plurality of wings includes a third wing and a fourth wing; the third wing and the fourth wing are offset from each other in a longitudinal direction; and the third wing and the fourth wing retain an insulator of the electrical wire.

15. A method of assembling a terminal assembly, the method comprising:
providing a first terminal, the first terminal including a terminal body, a first wing, and a second wing, the first wing and the second wing each including an end portion, a middle portion, and a connecting portion;
providing a second terminal, the second terminal including a terminal body, a first wing, and a second wing, the first wing and the second wing of the second terminal each including an end portion, a middle portion, and a connecting portion;
bending the end portion of the first wing of the first terminal and the end portion of the second wing of the first terminal to provide a first bent portion and a second bent portion of the first terminal;
crimping the first bent portion and the second bent portion of the first terminal onto a first wire;
bending the end portion of the first wing of the second terminal and the end portion of the second wing of the second terminal to provide a first bent portion and a second bent portion of the second terminal; and
crimping the first bent portion and the second bent portion of the second terminal onto a second wire; and
wherein a diameter of the first wire is larger than a diameter of the second wire; and, prior to bending and crimping, the first terminal is substantially similar to the second terminal.

16. The method of claim 15 , wherein bending the end portion of the first wing of the second terminal and the end portion of the second wing of the second terminal includes bending the end portion of the first wing of the second terminal and the end portion of the second wing of the second terminal to a greater degree than the bending of the end portion of the first wing and the end portion of the second wing of the first terminal.

17. The method of claim 15 , wherein the first terminal includes a third wing and a fourth wing, the third wing and the fourth wing each including an end portion, a middle portion, and a connecting portion.

18. The method of claim 15 , wherein bending the end portion of the first wing of the first terminal and the end portion of the second wing of the first terminal includes bending the end portion of the first wing of the first terminal and the end portion of the second wing of the first terminal via a bending die, the bending die including a plurality of recesses.

19. The method of claim 18 , wherein the bending die includes a substantially flat bridge portion disposed between a first recess and a second recess of the plurality of recesses, and a width of the bridge portion is at least half as wide as the first recess and the second recess.

20. The method of claim 19 , wherein the first recess and the second recess include a first portion and a second portion; the first portion of the first recess contacts the end portion of the first wing of the first terminal during bending; and the second portion of the second recess contacts the end portion of the second wing of the first terminal.
