What is Banana Plug and How to Use It?

The cylindrical banana plug, also known as a 4mm connector, is utilized for electrical wiring. It has the fruit name “banana” since it has a projecting spike in the center. It does, however, have a spring-mounted fin that assures a secure connection when put into the equipment socket.

Now that we’ve recognized its structure and application, it’s vital to comprehend how we use the banana plug.¬†

How to Use Banana Plug?

Step 1: Cut the wires and separate them

Determine the length of wire you’ll need to get started. When you’re finished, make sure to tuck one end away to give yourself some breathing room. Also, if you’re going to wire from behind the wall, make sure you do so before you attach the banana plugs.

After that, you’ll need to separate the wires from one another so you can operate with each one separately. For ease, keep the wires apart by about an inch or two.

Step 2: Remove the Jacket to reveal the Bare Wire

Cut the cable about a half-inch away from the end of the cable to expose the wire. Place the wire stripper on the wire as needed and twist with light pressure to remove the jacket.

Remove the wire stripper and take off the jacket to reveal the bare wire once finished. This bare wire will be used to connect the banana plug to the wire. Carry on with the same process for the remaining wires.

Step 3: Connect the Banana Plugs to the Wire

As mentioned earlier, it’s time to feed the bare wire into the banana plugs. You won’t need a wire stripper in this situation. To guarantee a secure connection to the plug, you’ll need to twist the copper strands. Many wires can be positioned between the finger and thumb to do this. After that, slide your finger across the top of the wires to force them to twist around one another.

Now that the wires have been braided together, it’s time to connect the Strike banana plugs. However, there are two stripped plugs, one red and one black. The grey-coated cable connects to the red stripe plug, while the black cable connects to the black stripe plug.

Step-4: Feed the Speaker Wire into the Plugs

In this step, feed the speaker wire on the bottom of the red stripe plug as much as possible with the grey cable for a stronger connection. Then tighten the plug to enhance the connection’s strength. Repeat the procedure for the other stripe plug.

Step 5: Attach the Banana Plugs to the Speaker

After you’ve supplied the plugs with speaker wires, simply put them into the back-end of the speaker or receiver, and voila! You’re all set to go!
