Abstract

In some embodiments, a power terminal is in electrical connection to a power supply terminal, and a printed circuit board is supplied with a board to power contact. Bringing the board to power contact together with the PCB contact causes an electrical connection between the power supply and the PCB. In some embodiments the electrical connection resists disconnection from the PCB contact without requiring an external force on the PCB. In some embodiments the PCB-to-power-contact and the PCB contact are brought together in a direction perpendicular to a plane of the PCB. In some embodiments the PCB-to-power-contact includes fingers with grasp the PCB contact on two sides.

Claims

1. A method of mounting a printed circuit board (PCB) to a power supply comprising:

pushing the PCB into a position on a mounting U;

simultaneously engaging mechanically a PCB-to-power-contact connected to the PCB to a PCB contact connected to said mounting and electrically connecting said PCB-to-power-contact to said PCB contact;

fixing a location of said PCB contact with respect to said mounting;

locating a power supply terminal separate from said fixing of said PCB contact; and

joining said PCB contact to said power supply terminal with an adaptor element.

2. The method of claim 1, wherein said engaging includes forming a friction contact between said PCB-to-power-contact and said PCB contact.

3. The method of claim 2, wherein said engaging includes clasping a rail from opposite sides.

4. The method of claim 3, wherein said engaging includes sliding said rail between two fingers, wherein said two fingers are mounted parallel to a direction of said pushing.

5. The method of claim 4, wherein said sliding includes elastically deforming said fingers to admit said rail between said fingers.

6. The method of claim 4, wherein a first force between at least one of said fingers and said rail is at least partially balanced by a second force between at least a second of said fingers and said rail.

7. The method of claim 4, wherein, a net force on said rail is less than a tenth of a sum of magnitudes of individual forces on said rail.

8. The method of claim 1, further comprising directing the PCB to said position with a guide.

9. The method of claim 1, wherein said pushing is in a direction substantially perpendicular to a plane of the PCB.

10. The method of claim 1, wherein after said engaging, said PCB-to-power-contact resists disconnection from said PCB contact without requiring an external force.

11. The method of claim 1, wherein after said engaging, said electrically connecting remains stable without stressing the PCB.

12. A system for mounting a printed circuit board (PCB) to a power supply comprising:

a PCB contact positioned on a mounting for the PCB in a fixed position with respect to the mounting;

a PCB-to-power-contact positioned on the PCB;

a friction contact mechanically engaging and electrically connecting the PCB-to-power-contact to said PCB contact;

a power supply terminal having a position fixed separately from the fixed position of the PCB contact; and

an adaptor element joining the PCB contact to the power supply terminal.

13. The system of claim 12, wherein said friction contact includes at least two fingers extending perpendicular to a plane of the PCB, said fingers configured for sliding onto opposite sides of a rail.

14. The system of claim 13, wherein in an unstressed state said fingers are positioned on opposite sides of a gap and wherein said gap is configured for sliding a rail into said gap, elastically deforming said fingers to grasp opposite sides of said rail.

15. The system of claim 13, wherein during said mechanical engaging, said at least two fingers are elastically stressed by said rail in opposing directions by forces from said rail that at least partially counter balance each other, a net force being less than a sum of magnitudes of individual forces.

16. The system of claim 15, wherein during said mechanical engaging, said at least two fingers are elastically stressed in a direction substantially parallel to a plane of said PCB.

17. The system of claim 13, wherein during said mechanical engaging, said at least two fingers are elastically stressed by said rail in opposing directions by forces from said rail that at least partially counter balance each other, a net force being less than a tenth of a sum of magnitudes of individual forces.

18. The system of claim 12, further comprising:

a guide positioned on said mounting, said guide configured to direct said positioning prior to said engaging of said friction contact.

19. The system of claim 12, wherein said friction contact is configured for said engaging in response to pushing in a direction substantially perpendicular to a plane of the PCB.

20. The system of claim 12, wherein after said engaging, the PCB-to-power-contact resists disconnection from said PCB contact without requiring an external force.
