High power fuse terminal with scalability
View Patent ↗A female terminal receptor for an automotive fuse or a terminal includes three or more pairs of opposing beams and at least one U-shaped clamping member. The U-shaped clamping member has a first base portion laterally disposed between two pairs of opposing beams and at least one pair of first end portions disposed over at least one pair of opposing beams for applying a predetermined compression force. The opposing beams have a first metallic composition and the U-shaped clamping member has a second metallic composition, wherein the first metallic composition has a higher conductivity than the second metallic composition, and wherein the second metallic composition has a higher relaxation temperature than the first metallic composition.
1. An automotive fuse for coupling to a power distribution box, wherein the power distribution box includes first and second blade terminals, the fuse comprising:
a first terminal receptor including three or more pairs of first opposing beams and at least one first U-shaped clamping member, wherein each pair of first opposing beams spreads apart to receive the first blade terminal, wherein the first U-shaped clamping member has a first base portion laterally disposed between two pairs of first opposing beams and at least one pair of first end portions disposed over at least one pair of first opposing beams for applying a predetermined compression force; and
a second terminal receptor including three or more pairs of second opposing beams and at least one second U-shaped clamping member, wherein each pair of second opposing beams spreads apart to receive the second blade terminal, wherein the second U-shaped clamping member has a second base portion laterally disposed between two pairs of second opposing beams and at least one pair of second end portions disposed over at least one pair of second opposing beams for applying the predetermined compression force;
wherein the opposing beams have a first metallic composition and the U-shaped clamping members have a second metallic composition, wherein the first metallic composition has a higher conductivity than the second metallic composition, and wherein the second metallic composition has a higher relaxation temperature than the first metallic composition.
2. The automotive fuse of claim 1 wherein the opposing beams all have substantially the same width and are evenly spaced.
3. The automotive fuse of claim 1 wherein the first metallic composition comprises copper.
4. The automotive fuse of claim 1 wherein the first metallic composition comprises an alloy of copper with about 0.1% zirconium.
5. The automotive fuse of claim 1 wherein the second metallic composition comprises stainless steel.
6. The automotive fuse of claim 1 wherein the first and second U-shaped clamping members are each comprised of two or more separate spring members retained between different pairs of opposing beams.
7. The automotive fuse of claim 1 wherein the first and second blade terminals have a first predetermined thickness, wherein each pair of opposing beams is separated by less than the first predetermined thickness while in their rest positions, wherein each pair of opposing beams have a second aggregate thickness in the area where they are contacted by respective end portions, and wherein the end portions disposed over respective opposing beams are separated by less than the sum of the first predetermined thickness and the second aggregate thickness while in their rest positions.
8. A female terminal for an electrical connector for connecting to a male blade terminal, comprising:
a first terminal receptor including three or more pairs of opposing beams; and
at least one first U-shaped clamping member,
wherein each pair of opposing beams spreads apart to receive the blade terminal, wherein the first U-shaped clamping member has a base portion laterally disposed between two pairs of opposing beams and at least one pair of end portions disposed over at least one pair of opposing beams for applying a predetermined compression force, wherein the opposing beams have a first metallic composition and the U-shaped clamping member has a second metallic composition, wherein the first metallic composition has a higher conductivity than the second metallic composition, and wherein the second metallic composition has a higher relaxation temperature than the first metallic composition.
9. The female terminal of claim 8 wherein the opposing beams all have substantially the same width and are evenly spaced.
10. The female terminal of claim 8 wherein the first metallic composition comprises copper.
11. The female terminal of claim 8 wherein the first metallic composition comprises an alloy of copper with about 0.1% zirconium.
12. The female terminal of claim 8 wherein the second metallic composition comprises stainless steel.
13. The female terminal of claim 8 wherein the U-shaped clamping member is comprised of two or more separate spring members retained between different pairs of opposing beams.
14. The female terminal of claim 8 wherein the blade terminal has a first predetermined thickness, wherein each pair of opposing beams is separated by less than the first predetermined thickness while in their rest positions, wherein each pair of opposing beams have a second aggregate thickness in the area where they are contacted by respective end portions, and wherein the end portions disposed over respective opposing beams are separated by less than the sum of the first predetermined thickness and the second aggregate thickness while in their rest positions.
