Abstract

A circuit board connector is disclosed that has isolator ribs between contact tails, and slots in the edge of a circuit board between circuit pads that communicate with the ribs to avoid pad-to-pad current leakage and high-voltage breakdown. The slots may be between individual circuit board fingers that each include one of the conductor pads.

First claim

What is claimed is:

1. A device comprising:
a circuit board; and
a connector mounted on an edge of the circuit board;
wherein the circuit board has contact pads away from an edge of the circuit board that is closest to the connector;
wherein the connector has ribs alternating with contact tails; and
wherein the contact tails engage the contact pads;
wherein the circuit board has slots that are between adjacent circuit board fingers; and
wherein the slots have a depth that extends further from the edge than do the contact pads.

2. The device of claim 1 , wherein the contact pads are on individual circuit board fingers.

3. The device of claim 1 , wherein the slots are rectangular slots.

4. The device of claim 1 , wherein the ribs enter the slots when the connector is coupled to the circuit board.

5. The device of claim 1 , wherein the ribs are between adjacent contact pads, extending the isolation path between the adjacent contact pads.

6. The device of claim 1 , wherein the ribs are parts of a plastic connector body of the connector.

7. The device of claim 6 , wherein the connector body is a single molded plastic piece.

8. The device of claim 1 , wherein the contact pads have respective conductive vias that electrically connect the conductive pads to circuitry of the circuit board.

9. The device of claim 8 , wherein the circuitry is within (inside) the circuit board, as opposed to being on a surface of the circuit board.

10. The device of any of claim 1 , wherein the combination of the ribs and the slots provides an extended isolation path preventing current leakage and voltage breakdown.

11. A circuit board comprising:
circuit board fingers with slots therebetween; and
contact pads, away from an edge of the circuit board, on the circuit board fingers;
wherein the circuit board has slots that are between adjacent circuit board fingers; and
wherein the slots have a depth that extends further from the edge than do the contact pads.

12. The device of claim 11 , wherein the slots are rectangular slots.
