Abstract

Electrical resistance between a male part and a female part through a canted spring is disclosed using mathematical modeling. Increase or decrease in resistance can be quickly analyzed by looking at the equivalence resistance and the number of contacts at the input side, the output side, or both. The number of contacts may also be created by forming a dimple having a discontinuity.

Claims (29)

1. A method of manufacturing an electrical connector with an equivalent resistance comprising:

providing a housing made from, at least in part, an electrically conductive material;

providing a pin made from, at least in part, an electrically conductive material;

positioning a canted coil spring comprising a spring coil in a groove, said groove being associated with the housing, the pin, or both; and

counting a first set of number of contact point or points between the spring coil and the housing and a second set of number of contact point or points between the spring coil and the pin;

using Ohm's Law, the first set of number of contact point or points, and the second set of number of contact point or points to compute the equivalent resistance for the electrical connector.

2. The method of manufacturing of claim 1 , further comprising associating the groove with the housing only.

3. The method of manufacturing of claim 1 , further comprising associating the groove with the pin only.

4. The method of manufacturing of claim 1 , wherein the first set of number of contact point or points is one, and the second set of number of contact point or points is one.

5. The method of manufacturing of claim 1 , wherein the first set of number of contact point or points or the second set of number of contact point or points is two by forming a V-shape bottom wall in the groove.

6. The method of manufacturing of claim 1 , wherein the first set of number of contact point(s) or the second set of number of contact point or point is two by forming a dimple on the coil to define a section having a discontinuity.

7. The method of manufacturing of claim 1 , wherein the first set of number of contact point or points or the second set of number of contact point or points is two by forming the groove with two tapered sidewalls relative to a bottom wall.

8. The method of manufacturing of claim 1 , wherein the contact between the spring coil and the housing or between the spring coil and the pin is along an arc length of the coil.

9. The method of manufacturing of claim 1 , further comprising determining a first path length of the spring coil between the housing and the pin and a second path length of the spring coil between the housing and the pin.

10. The method of manufacturing of claim 9 , further comprising using Ohm's Law, the first path length of the spring coil between the housing and the pin, and the second path length of the spring coil between the housing and the pin to compute the equivalent resistance for the electrical connector.

11. A method of manufacturing an electrical connector with an equivalent resistance comprising:

providing a housing made from, at least in part, an electrically conductive material;

providing a pin made from, at least in part, an electrically conductive material;

positioning a canted coil spring comprising a spring coil in a groove, said groove being associated with the housing, the pin, or both;

counting a first set of number of contact point or points between the spring coil and the housing and a second set of number of contact point or points between the spring coil and the pin; and

determining a first path length of the spring coil between the housing and the pin and a second path length of the spring coil between the housing and the pin;

using Ohm's Law, the first set of number of contact point or points, the second set of number of contact point or points, the first path length of the spring coil between the housing and the pin, and the second path length of the spring coil between the housing and the pin to compute the equivalent resistance for the electrical connector.

12. The method of manufacturing of claim 11 , further comprising associating the groove with the housing only.

13. The method of manufacturing of claim 11 , further comprising associating the groove with the pin only.

14. The method of manufacturing of claim 11 , wherein the first set of number of contact point or points is one, and the second set of number of contact point or points is one.

15. The method of manufacturing of claim 11 , wherein the first set of number of contact point or points or the second set of number of contact point or points is two by forming a V-shape bottom wall in the groove.

16. The method of manufacturing of claim 11 , wherein the first set of number of contact point or points or the second set of number of contact point or points is two by forming a dimple on the coil to define a section having a discontinuity.

17. The method of manufacturing of claim 11 , wherein the first set of number of contact point or points or the second set of number of contact point or points is two by forming the groove with two tapered sidewalls relative to a bottom wall.

18. The method of manufacturing of claim 11 , wherein the contact between the spring coil and the housing or between the spring coil and the pin is along an arc length of the coil.
