Abstract

In accordance with one embodiment, an electrical connector includes a connector housing, and at least one electrical terminal supported by the connector housing. The electrical terminal defines a mating portion and a mounting portion, the mounting portion carrying a crimp member having crimp teeth configured to pierce through a flex cable when crimped so as to mount the flat flex cable to the mounting portion of the electrical terminal.

Claims

1. An electrical terminal comprising:

a mating portion defining a contact surface that is configured to removably electrically connect to an electrical terminal of a complementary electrical component; and

a mounting portion including a mounting member and a crimp member that extends from the mounting member, the crimp member having flexible crimp teeth that, when the mounting portion of the electrical terminal is mounted to a flat flex cable, crimp so as to

     1) pierce through the flat flex cable along a first direction, and

     2) fold back and pierce into the flat flex cable along a second direction substantially opposite the first direction,

wherein the crimp member extends from the mounting member along a direction that is substantially parallel to a direction in which the mating portion is spaced from the mounting portion.

2. The electrical terminal as recited in claim 1, wherein the crimp member extends from the mounting member along a direction away from the contact surface.

3. The electrical connector as recited in claim 1, wherein the crimp member extends from the mounting member along a direction toward the contact surface.

4. The electrical terminal as recited in claim 1, wherein the mating portion includes a proximal region, a distal region, and a flexible bent intermediate region connected between proximal region and the distal region, wherein the proximal region defines a contact surface configured to contact a complementary electrical terminal, thereby causing the flexible bent intermediate region to flex such that the proximal region compresses toward the distal region.

5. The electrical terminal as recited in claim 4, wherein the proximal region compresses along a direction that is substantially the same as a direction from which the crimp member extends from the mounting member.

6. The electrical terminal as recited in claim 4, wherein the proximal region compresses along a direction that is substantially opposite a direction from which the crimp member extends from the mounting member.

7. The electrical terminal as recited in claim 4, wherein the proximal region carries a retention member configured to secure the electrical terminal to a connector housing, and the proximal region overlaps the mounting portion.

8. The electrical terminal as recited in claim 7, wherein the distal region overlaps the proximal region and the mounting portion.

9. The electrical terminal as recited in claim 1, further comprising an intermediate portion that is connected between the mating portion and the mounting portion, wherein the mating portion and the mounting portion extend from spaced first and second locations, respectively, of the intermediate portion.

10. The electrical terminal as recited in claim 9, wherein the mating portion and the mounting portion extend from the intermediate portion in the same direction such that the mating portion and the mounting portion overlap each other.

11. The electrical terminal as recited in claim 10, wherein the mating portion defines a proximal region, a distal region, and a bent region that is connected between the proximal and distal regions, such that the proximal and distal regions overlap each other.

12. The electrical terminal as recited in claim 11, wherein the bent region defines a substantially 180°

bend.

13. The electrical terminal as recited in claim 1, wherein each of the crimp teeth defines a tapered distal end.

14. An electrical connector assembly, comprising:

a connector housing that includes a first housing surface that defines a mating interface configured to mate with a complementary electrical connector, and a second housing surface that defines a mounting interface that is configured to secure to a flat flex cable;

at least one electrical terminal supported by the housing, the electrical terminal defining a mating portion that faces out from the first housing surface, and a mounting portion that includes at least one crimp member that includes a plurality of crimp teeth that face out from the second surface and are configured to pierce the flat flex cable so as to electrically connect the mounting portion of the electrical terminal to the flat flex cable, the mating portion including a proximal region, a distal region, and a flexible bent intermediate region connected between proximal region and the distal region, wherein the proximal region defines a contact surface configured to contact a complementary electrical terminal, thereby causing the flexible bent intermediate region to flex such that the proximal region compresses toward the distal region; and

a strain relief assembly configured to compress the flat flex cable against the connector housing after the mounting portion of the electrical terminal has been electrically connected to the flex cable,

wherein the crimp member extends from the mounting member along a direction that is substantially parallel to a direction in which the mating portion is spaced from the mounting portion.

15. The electrical terminal as recited in claim 14, wherein the crimp member extends from the mounting member along a direction away from the mating portion.

16. The electrical connector as recited in claim 14, wherein the crimp member extends from the mounting member along a direction toward the mating portion.

17. The electrical terminal as recited in claim 14, wherein the proximal region compresses along a direction that is substantially the same as a direction from which the crimp member extends from the mounting member.

18. The electrical terminal as recited in claim 14, wherein the proximal region compresses along a direction that is substantially opposite a direction from which the crimp member extends from the mounting member.

19. An electrical terminal comprising:

a mating portion including a proximal region, a distal region, and a flexible bent intermediate region connected between proximal region and the distal region, wherein the proximal region defines a contact surface configured to contact an electrical terminal of a complementary electrical component so as to removably electrically connect to the electrical terminal, thereby causing the flexible bent intermediate region to flex such that the proximal region compresses toward the distal region; and

a mounting portion including a mounting member and a crimp member that extends from the mounting member, the crimp member having flexible crimp teeth configured to pierce through a flat flex cable along a first direction so as to mount the flat flex cable to the mounting portion of the electrical terminal,

wherein the crimp member extends from the mounting member along a direction that is substantially parallel to a direction in which the mating portion is spaced from the mounting portion.

20. The electrical terminal as recited in claim 19, wherein the proximal region compresses along a direction that is substantially the same as a direction from which the crimp member extends from the mounting member.

21. The electrical terminal as recited in claim 19, wherein the proximal region compresses along a direction that is substantially opposite a direction from which the crimp member extends from the mounting member.

22. The electrical terminal as recited in claim 19, wherein the proximal region carries a retention member configured to secure the electrical terminal to a connector housing, and the proximal region overlaps the mounting portion.

23. The electrical terminal as recited in claim 22, wherein the distal region overlaps the proximal region and the mounting portion.

24. The electrical terminal as recited in claim 19, wherein the flexible crimp teeth are further configured to fold back and pierce into the flat flex cable along a second direction substantially opposite the first direction when crimped so as to mount the flat flex cable to the mounting portion of the electrical terminal.
