Abstract

A connector system is configured for macro motion. Two mating terminals are configured so that during macro motion cycles, the resistance between two terminals does not substantially increase. One terminal can have multiple, somewhat spherical-shaped mating surfaces while a mating surface on the other terminal can be flat. The mating terminals can be configured to provide desirable resistance performance after more than 5000 cycles of macro motion.

First claim

We claim:

1. A energy transfer system, comprising:
a first panel supporting a first header with a first terminal and a second header with a second terminal, the first and second headers being on opposing sides of the first panel;
a second panel supporting a third header with a third terminal, wherein the first panel and the second panel are configured to be mounted adjacent each other; and
a connector with a first end and a second end, the first end configured to mate with the first header and the second end configured to mate with the third header, the connector including a fourth terminal configured to electrically couple the first and third terminals, wherein the first, third and fourth terminals are configured to provide a resistance between the first and third terminals that increases less than 20 milliohms after 5000 cycles of macro motion between the first and second panels.

2. The energy transfer system of claim 1 , wherein the starting resistance is less than about 10 milliohms.

3. The energy transfer system of claim 1 , wherein the resistance increase less than 20 milliohms over 7000 macro cycles.

4. The energy transfer system of claim 1 , wherein the resistance increases less than 20 milliohms over 15000 macro cycles.

5. The energy transfer system of claim 1 , wherein the macro motion is at least 0.50 mm.

6. The energy transfer system of claim 1 , wherein the macro motion is at least 1.0 mm.

7. The energy transfer system of claim 1 , wherein each macro motion cycle occurs during a temperature change that is an average of at least 30 C.

8. The energy transfer system of claim 7 , wherein the temperature change is an average of at least 40 C.

9. The energy transfer system of claim 1 , wherein the resistance increase is less than 10 milliohms.

10. The energy transfer system of claim 1 , wherein the fourth terminal includes a first end and a second end that each include bifurcated fingers, the bifurcated fingers configured to engage opposing sides of the corresponding first and third terminals.

11. An energy transfer system, comprising:
a first panel configured for securely mounting on a base and including a first header with a first pair of terminals and a second header with a second pair of terminals, the first and second headers being on opposing sides of the first panel, the first panel having a first coefficient of thermal expansion;
a second panel configured for securely mounting on the base and including a third header with a third pair of terminals, the second panel having a second coefficient of thermal expansion, the first and second coefficients of thermal expansion being configured such that when the first and second panels are secured to the base adjacent each other, the first header and the second header will vary at least 0.25 mm in response to a temperature variation of 30 degrees C.; and
a connector configured to mate to the first header and the second header, the connector including a fourth pair of terminals configured to respectively electrically couple the first and third pairs of terminals, each terminal of the fourth pair of terminals configured to provide a resistance between the corresponding terminals of the first and third pairs of terminals that is less than 30 milliohms after at least 5000 cycles of macro motion.

12. The energy transfer system of claim 11 , wherein the first, third and fourth pairs of terminals are configured so that the resistance is less than 30 milliohms after at least 7000 cycles of macro motion.

13. The energy transfer system of claim 11 , wherein the terminals are configured so that the resistance is less than 20 milliohms after at least 10000 cycles.

14. The energy transfer system of claim 11 , wherein at least one of the pairs of terminals is configured to provide at least 0.50 mm of wipe.

15. The energy transfer system of claim 11 , wherein each terminal of the fourth pair of terminals has a first and second end, the first and second ends each having multiple fingers.

16. The energy transfer system of claim 15 , wherein the multiple fingers are configured to engage opposing sides of corresponding first and third pairs of terminals.

17. The energy transfer system of claim 15 , wherein each of the fingers has a mating surface with a first radius extending between edges of the finger and a second radius in a direction of translation during macro motion, the first radius being greater than the second radius.

18. The energy transfer system of claim 15 , wherein each finger presses on a corresponding surface of the terminals of the first and second pairs of terminals with a force that is less than 100 grams.

19. The energy transfer system of claim 11 , wherein one of the first pair of terminals and the fourth pair of terminals includes an end with bifurcated fingers and each finger presses on a corresponding surface of the other terminals with a force that is less than 100 grams.

20. The energy transfer system of claim 19 , wherein the end includes two sets of opposing fingers.

21. The energy transfer system of claim 11 , wherein each of the first and second panels includes a solar conversion region.
