Electrical terminal assembly
View Patent ↗An electrical terminal assembly includes a base and a spring member. The base defines an axis and includes a plurality of base beams deflectable toward the axis. The spring member has a main portion that is disposed over the base, and a plurality of spring beams that extend from the main portion. The spring beams bias the base beams toward the axis. The main portion of the spring member is made from a folded blank having a first edge that is permanently secured to a second edge such that the edges cannot be pulled apart from one another.
1. An electrical terminal assembly comprising:
a base including a box-shaped main portion having four walls that are generally oriented at ninety degrees relative to one another, each of the four walls of the base having a base beam extending therefrom;
a spring member including a box-shaped main portion having four walls that are generally oriented at ninety degrees relative to one another, each of the four walls of the spring member having a spring beam extending therefrom, the box-shaped main portion of the spring member being disposed about the box-shaped main portion of the base such that the spring beams of the spring member urge the base beams of the base toward one another;
first securing features provided on the base and the spring member that cooperate to prevent movement of the base relative to the spring member in a first axial direction; and
second securing features provided on the base and the spring member that cooperate to prevent movement of the base relative to the spring member in a second axial direction that is opposite to the first axial direction,
wherein either (1) each of the four walls of the base has a plurality of base beams extending therefrom, or (2) each of the four walls of the spring member has a single spring beam extending therefrom.
2. The electrical terminal assembly defined in claim 1 wherein the box-shaped main portion of the base is made from a folded blank having first and second edges that abut one another in a non-overlapping manner.
3. The electrical terminal assembly defined in claim 1 wherein the box-shaped main portion of the spring member is made from a folded blank having first and second edges that abut one another in a non-overlapping manner.
4. The electrical terminal assembly defined in claim 1 wherein both (1) the box-shaped main portion of the base is made from a folded blank having first and second edges that abut one another in a non-overlapping manner, and (2) the box-shaped main portion of the spring member is made from a folded blank having first and second edges that abut one another in a non-overlapping manner.
5. The electrical terminal assembly defined in claim 1 wherein the first securing features provided on the base and the spring member include a tab provided on the base that cooperates with an edge of an opening provided on the spring member.
6. The electrical terminal assembly defined in claim 1 wherein the second securing features provided on the base and the spring member include an edge of an opening provided on the base that cooperates with a finger provided on the spring member.
7. The electrical terminal assembly defined in claim 1 wherein both (1) the first securing features provided on the base and the spring member include a tab provided on the base that cooperates with an edge of an opening provided on the spring member, and (2) the second securing features provided on the base and the spring member include an edge of an opening provided on the base that cooperates with a finger provided on the spring member.
8. The electrical terminal assembly defined in claim 1 wherein each of the four walls of the base has a plurality of base beams extending therefrom, and wherein each of the four walls of the spring member has a single spring beam extending therefrom.
9. The electrical terminal assembly defined in claim 1 wherein each of the four walls of the base has a plurality of base beams extending therefrom.
10. The electrical terminal assembly defined in claim 9 wherein each of the four walls of the spring member has a single spring beam extending therefrom.
11. The electrical terminal assembly defined in claim 1 wherein the box-shaped main portion of the spring member is made from a folded blank having first and second edges that abut one another in an overlapping manner.
12. The electrical terminal assembly defined in claim 11 wherein the first edge has a tab extending therefrom that overlaps a flap extending from the second edge.
13. The electrical terminal assembly defined in claim 11 wherein the first edge has a tab extending therefrom that overlaps each of two flaps extending from the second edge.
14. An electrical terminal assembly comprising:
a base including a box-shaped main portion having four walls that are generally oriented at ninety degrees relative to one another, each of the four walls of the base having a base beam extending therefrom;
a spring member including a box-shaped main portion having four walls that are generally oriented at ninety degrees relative to one another, each of the four walls of the spring member having a spring beam extending therefrom, the box-shaped main portion of the spring member being disposed about the box-shaped main portion of the base such that the spring beams of the spring member urge the base beams of the base toward one another;
a tab provided on the base that cooperates with an edge of an opening provided on the spring member to prevent movement of the base relative to the spring member in a first axial direction; and
an edge of an opening provided on the base that cooperates with a finger provided on the spring member to prevent movement of the base relative to the spring member in a second axial direction that is opposite to the first axial direction.
15. The electrical terminal assembly defined in claim 14 wherein the box-shaped main portion of the base is made from a folded blank having first and second edges that abut one another in a non-overlapping manner.
16. The electrical terminal assembly defined in claim 14 wherein the box-shaped main portion of the spring member is made from a folded blank having first and second edges that abut one another in a non-overlapping manner.
17. The electrical terminal assembly defined in claim 14 wherein both (1) the box-shaped main portion of the base is made from a folded blank having first and second edges that abut one another in a non-overlapping manner, and (2) the box-shaped main portion of the spring member is made from a folded blank having first and second edges that abut one another in a non-overlapping manner.
18. The electrical terminal assembly defined in claim 14 wherein the box-shaped main portion of the spring member is made from a folded blank having first and second edges that abut one another in an overlapping manner.
19. The electrical terminal assembly defined in claim 14 wherein the first edge has a tab extending therefrom that overlaps a flap extending from the second edge.
20. The electrical terminal assembly defined in claim 14 wherein the first edge has a tab extending therefrom that overlaps each of two flaps extending from the second edge.
