Quick install banana plug

1. A system, comprising:

a banana plug including

a pin,

a spring coupled to the pin, the spring having an arm, the arm defining an aperture,

wherein the spring at the aperture has a clamping portion configured to secure a wire against the spring,

wherein the spring has an opened position configured to receive the wire through the aperture,

wherein the spring has a closed position where the wire is clamped to the spring, and

a lever configured to actuate the spring to the opened position.

2. The system of claim 1 , wherein the spring is biased to the closed position.

3. The system of claim 1 , wherein the pin has one or more leaves bowing away from the pin.

4. The system of claim 1 , wherein the lever is configured to apply a compressive force to the spring in an actuation position to actuate the spring to the opened position.

5. The system of claim 4 , wherein the lever is configured to release the compressive force in a released position to release the spring to the closed position.

6. The system of claim 1 , further comprising:

a binding post; and

wherein the banana plug is plugged into the binding post.

7. The system of claim 6 , wherein:

the binding post has a binding post spring;

the binding post spring defines a binding post spring aperture with a binding post clamping portion configured to secure a binding post wire with the binding post spring;

the binding post spring has an opened position configured to receive the binding post wire through the binding post spring aperture;

the binding post spring has a closed position where the binding post wire is clamped to the binding post spring;

the binding post has a binding post lever; and

the binding post lever is configured to actuate the binding post spring to the opened position.

8. The system of claim 1 , wherein:

the spring has a guiding portion;

the guiding portion extends through the aperture in the arm of the spring; and

the clamping portion is configured to direct the wire into contact with the guiding portion when

the spring is in the closed position.

9. The system of claim 8 , wherein:

the guiding portion includes a busbar;

the busbar having a flange to which the pin is attached; and

the busbar being configured to provide an electrical connection between a wire and the pin.

10. The system of claim 8 , wherein:

the clamping portion of the spring at the aperture is positioned opposite to the guiding portion; and

the wire is sandwiched between the clamping portion and the guiding portion when the spring is at the closed position.

11. The system of claim 1 , wherein:

the banana plug has a body; and

the pin extends from the body.

12. The system of claim 11 , wherein:

the body defines a channel; and

the channel is configured to retain the lever to prevent accidental rotation of the lever.

13. The system of claim 12 , wherein the lever is configured to extend out of the channel when pivoted to compress the spring to the open position.

14. A system, comprising:

a binding post including

an outlet end,

a spring coupled to the outlet end, the spring having an arm, the arm defining an aperture,

wherein the spring at the aperture has a clamping portion configured to secure a wire against the spring,

wherein the spring has an opened position configured to receive the wire through the aperture,

wherein the spring has a closed position where the wire is clamped to the spring, and

a lever configured to actuate the spring to the opened position.

15. The system of claim 14 , further comprising:

an outlet cover; and

wherein the binding post is coupled to the outlet cover.

16. The system of claim 14 , further comprising:

a banana plug including a lever configured to actuate an internal spring; and

wherein the banana plug is plugged into the binding post.

17. A method, comprising:

opening an aperture in a spring of an electrical connector to an open position by actuating the spring with a lever of the electrical connector;

inserting a wire through the aperture in the spring;

rotating the lever to a released position to release the spring to a closed position where the wire in the aperture is clamped by the spring;

wherein the electronical connector has a pin; and

inserting the pin into a binding post.

18. The method of claim 17 , wherein the electrical connector is a banana plug.

19. The method of claim 18 , further comprising: plugging the banana plug into the binding post.
