Tool for disconnecting a connector

1. A tool comprising:

a first arm comprising first handle and a first part having a first notch, the first notch for engaging a first connector connected to a circuit board;

a second arm comprising a second handle and a second part having a second notch, the second notch for engaging a second connector connected to a cable; and

a hinge to connect the first arm to the second arm;

wherein the hinge is biased so that, when the tool is not in use, the first handle and the second handle are apart and also the first part and the first notch are flush against the second part and the second notch.

2. The tool of claim 1 , further comprising:

a spring to bias the hinge.

3. The tool of claim 2 , wherein the spring is wound around the hinge and includes fingers that contact, to bias, the first arm and the second arm.

4. The tool of claim 1 , wherein the first handle and the second handle align longitudinally, and the hinge is located partway along the first arm and the second arm.

5. The tool of claim 1 , wherein the hinge is between the first handle and the first notch and between the second handle and the second notch.

6. The tool of claim 1 , wherein the second notch is configured to engage a groove in the second connector.

7. The tool of claim 1 , wherein the first part is configured to remain flush against an edge of the circuit board when the first notch engages the first connector.

8. The tool of claim 1 , wherein the first arm and the second arm comprise structures containing holes that align; and

wherein the hinge comprises a shoulder screw and a retaining nut, the shoulder screw for fitting within the holes and the retaining nut for engaging the shoulder screw.

9. The tool of claim 1 , wherein the hinge is biased so that, when the tool is in use, the first handle and the second handle move closer together and the first notch and the second notch move farther apart.

10. The tool of claim 9 , wherein movement of the first notch and the second notch farther apart causes the second connector to disconnect from the first connector.

11. The tool of claim 9 , wherein movement of the first notch and the second notch farther apart causes at least eleven pounds of force to be applied to the second connector in a direction away from the circuit board.

12. The tool of claim 1 , wherein the tool comprises metal that is produced by a three-dimensional printing process.

13. A tool comprising:

a support to maintain contact with an edge of a circuit board; and

a lever attached to the support part-way along a longitudinal dimension of the tool, the lever being attached to enable the lever to pivot relative to the support, the lever comprising a notch to engage a connector that is connected to the circuit board such that pivoting the lever causes the connector to disconnect from the circuit board;

wherein, when the tool is not in use, the hinge is biased so that the lever and the notch are flush against the support.

14. The tool of claim 13 , further comprising:

a hinge to attach the lever to the support.

15. The tool of claim 14 , further comprising:

a spring to bias the hinge.

16. The tool of claim 15 , wherein the spring is wound around the hinge and includes fingers that contact, to bias, at least one of the lever or the support.

17. The tool of claim 14 , wherein the support and the lever align longitudinally, and the hinge is located partway along the lever and the support.

18. The tool of claim 14 , further comprising:

a first handle connected to the support; and

a second handle connected to the lever;

wherein the hinge is biased so that, when the tool is in use, the lever and the support move farther apart while the first handle and the second handle move closer together.

19. The tool of claim 13 , wherein the connector is a sub-miniature push-on (SMP) connector.

20. The tool of claim 13 , wherein pivoting applies a force of at least eleven pounds to disconnect the connector from the circuit board.
