Abstract

An electrical terminal includes a contact member. The contact member includes a contact base. The contact member includes a plurality of contact arms extending from the contact base. The contact arms are arranged on opposed sides of a terminal plane. The electrical terminal also includes a spring member. The spring member includes a spring base. The spring member includes a plurality of spring arms. The spring arms extend from the spring base. Each of the spring arms engages one or more of the contact arms. The spring member also includes a shroud. The shroud is connected to the spring base and extends around the contact arms and beyond the contact arms. The spring member is symmetrical across the terminal plane.

First claim

What is claimed is:

1. A female electrical terminal assembly that is configured to mate with a blade-type male terminal comprising:
a contact member including a contact base and a plurality of opposed pairs of contact arms extending from the contact base, each of the opposed pairs of contact arms including first and second contact arms arranged on opposed sides of a terminal plane so as to be configured to mate with a blade-type male terminal extending therebetween;
a spring member including a spring base, a plurality of spring arms extending from the spring base and engaging one or more of the opposed pairs of contact arms, and a shroud that is connected to the spring base and extends around the contact arms and beyond the contact arms,
the spring member being symmetrical across the terminal plane.

2. The female electrical terminal assembly of claim 1 , wherein the shroud includes a first shroud portion that is separated from a second shroud portion by two shroud gaps.

3. The female electrical terminal assembly of claim 2 , wherein the terminal plane passes through the shroud gaps.

4. The female electrical terminal assembly of claim 2 , wherein the terminal gaps are located on opposite sides of the contact arms.

5. The female electrical terminal assembly of claim 2 , wherein the first shroud portion includes a first side shield and the second shroud portion includes a second side shield, and wherein the terminal plane passes through the first side shield and the second side shield.

6. The female electrical terminal assembly of claim 1 , wherein the contact base defines an interior space, and wherein the spring base is located in the interior space.

7. The female electrical terminal assembly of claim 1 , wherein the shroud is connected to the spring base by first and second shroud connectors that are each located on the terminal plane for an entire span between the spring base and the shroud.

8. A female electrical terminal assembly that is configured to mate with a blade-type male terminal comprising:
a contact member including a contact base and a plurality of opposed pairs of contact arms extending from the contact base, each of the opposed pairs of contact arms including first and second contact arms arranged on opposed sides of a terminal plane so as to be configured to mate with a blade-type male terminal extending therebetween;
a spring member including a spring base, a plurality of spring arms extending from the spring base and engaging one or more of the opposed pairs of contact arms, and a shroud that is connected to the spring base and extends around the contact arms and beyond the contact arms;
the spring member including first and second shroud connectors that connect the shroud to the spring base, each of the first and second shroud connectors extending along the terminal plane for an entire span between the spring base and the shroud.

9. The female electrical terminal assembly of claim 8 , wherein the spring member is symmetrical across the terminal plane.

10. The female electrical terminal assembly of claim 8 , wherein the shroud includes a first shroud portion that is separated from a second shroud portion by two shroud gaps.

11. The female electrical terminal assembly of claim 10 , wherein the shroud gaps are located on opposed sides of the terminal plane.

12. The female electrical terminal assembly of claim 10 , wherein the first shroud portion includes a first side shield and the second shroud portion includes a second side shield and the terminal plane passes through the first side shield and the second side shield.

13. The female electrical terminal assembly of claim 8 wherein the contact base defines an interior space, and wherein the spring base is located in the interior space.

14. The female electrical terminal assembly of claim 13 , wherein the shroud connectors are located in the interior space.

15. A female electrical terminal assembly that is configured to mate with a blade-type male terminal comprising:
a contact member including a contact base and a plurality of opposed pairs of contact arms extending from the contact base, each of the opposed pairs of contact arms including first and second contact arms arranged on opposed sides of a terminal plane so as to be configured to mate with a blade-type male terminal extending therebetween;
a spring member including a spring base, a plurality of spring arms extending from the spring base and engaging one or more of the opposed pairs of contact arms, and a shroud that is connected to the spring base and extends around the contact arms and beyond the contact arms;
the shroud including a first shroud portion and a second shroud portion that are located on opposite sides of the terminal plane and are separated from each other by first and second shroud gaps.

16. The female electrical terminal assembly of claim 15 , wherein the terminal plane passes through the first and second shroud gaps.

17. The female electrical terminal assembly of claim 15 , wherein the spring base includes first and second outer bases, and wherein the plurality of spring arms extends from the first and second outer bases.

18. The female electrical terminal assembly of claim 17 , wherein the first and second outer bases are connected together by first and second base connectors.

19. The female electrical terminal assembly of claim 18 , wherein the contact base defines an interior space, and wherein the first and second base connectors extend through the interior space.
