Abstract

An electronic device includes a printed circuit board having at least one edge and a strain relief including a plurality of overlapping, spaced-apart slots that cooperate with the at least one edge to define a resilient tab for redistributing strain induced in the printed circuit board.

First claim

What is claimed is:

1. An electronic device, comprising:
a printed circuit board including at least one edge and a strain relief comprising a plurality of overlapping, spaced-apart slots that cooperate with the at least one edge to define a resilient tab for redistributing strain induced in the printed circuit board; and
a sensor provided on the printed circuit board such that the strain relief redistributes strain away from the sensor.

2. The electronic device recited in claim 1 , wherein the at least one edge includes first and second edges extending transverse to one another.

3. The electronic device recited in claim 2 , wherein the plurality of slots comprises:
a first slot extending from the first edge;
a second slot extending from the second edge; and
a third slot overlapping the first and second slots to form the resilient tab.

4. The electronic device recited in claim 3 further comprising an opening extending through the printed circuit board and being positioned on the resilient tab for receiving a fastener to secure the printed circuit board to an electronic component.

5. The electronic device recited in claim 4 , wherein the opening is centered on an axis and the third slot extends circumferentially about the axis.

6. The electronic device recited in claim 3 , wherein the first and second slots are linear and the third slot is arcuate.

7. The electronic device recited in claim 1 , wherein the printed circuit board is circular such that the at least one edge comprises a single edge encircling a centerline.

8. The electronic device recited in claim 7 , wherein the at least one slot comprises:
first and second slots extending from the single edge towards the centerline; and
a third slot overlapping the first and second slots to form the resilient tab.

9. The electronic device recited in claim 7 further comprising an opening extending through the printed circuit board and being positioned on the resilient tab for receiving a fastener to secure the printed circuit board to a substrate.

10. The electronic device recited in claim 9 , wherein the opening is centered on an axis and the third slot extends circumferentially about the axis.

11. The electronic device recited in claim 7 , wherein the first and second slots are linear and the third slot is arcuate.

12. An electronic device, comprising:
a printed circuit board including first and second edges extending transverse to one another and a strain relief comprising a plurality of overlapping, spaced-apart slots that cooperate with the first and second edges to define a resilient tab, the plurality of slots comprising:
a first slot extending away from the first edge;
a second slot extending away from the second edge; and
a third slot overlapping the first and second slots to form the resilient tab; and
a sensor provided on the printed circuit board such that the strain relief redistributes strain away from the sensor.

13. The electronic device recited in claim 12 , wherein the first and second edges extend transverse to one another, the first slot extending from the first edge and the second slot extending from the second edge.

14. The electronic device recited in claim 12 further comprising an opening extending through the printed circuit board and being positioned on the resilient tab for receiving a fastener to secure the printed circuit board to an electronic component.

15. The electronic device recited in claim 14 , wherein the opening is centered on an axis and the third slot extends circumferentially about the axis.

16. The electronic device recited in claim 12 , wherein the first and second slots are linear and the third slot is arcuate.

17. An electronic device, comprising:
a printed circuit board including at least one edge and a strain relief comprising a plurality of overlapping, spaced-apart slots that cooperate with the at least one edge to define a resilient tab for redistributing strain induced in the printed circuit board, the at least one edge including first and second edges extending transverse to one another, the plurality of slots including:
a first slot extending from the first edge;
a second slot extending from the second edge; and
a third slot overlapping the first and second slots to form the resilient tab.

18. The electronic device recited in claim 17 further comprising a sensor provided on the printed circuit board such that the strain relief redistributes strain away from the sensor.

19. The electronic device recited in claim 17 further comprising an opening extending through the printed circuit board and being positioned on the resilient tab for receiving a fastener to secure the printed circuit board to an electronic component.

20. The electronic device recited in claim 19 , wherein the opening is centered on an axis and the third slot extends circumferentially about the axis.

21. The electronic device recited in claim 19 , wherein the first and second slots are linear and the third slot is arcuate.
