Making and mending - DIY banana plugs

Banana plugs belong to electrical engineering, a small single-conductor electrical plug having a curved metal spring along its shank forming a clip to hold it in its socket. Banana connector is the most common speaker service drop wire connector, actually every speaker on the market has banana port. Although there are other connectors that can be used with speaker drop wire telephone cables (even without connectors, cables can be connected directly to speakers), banana plugs are usually the most useful.


Other types of speaker connectors are more difficult to use and a bit outdated, more fragile and unable to provide strong connections between triplex overhead wires and speakers. Technically, connecting the bare wire directly to the speaker provides better signals, but the bare wire that is not connected to the connector is more easily damaged and is worse than the signal provided by the banana plug. Connecting the drop wire cable directly to the speaker also makes it difficult to move the speaker, especially when compared to pulling out the cable only.


Some banana plugs are shrouded so that even when plugged in there is no way to touch any exposed metal. This test probe set also comes with alligator sc apc duplex adapters. The Banana plug test probes are used with multimeters, power supplies, and other electrical gear.

Step 1: Collecting the supplies.


There are some simple supplies that will be needed for an installation or repair. The key components are the banana connectors as well as the voltage drop across cable. Banana jacks can accept 12 AWG (American Wire Gauge) thick. Coarse cables will have strong signal strength but low flexibility. The most common variety of speaker cables is 16 AWG, which can balance signal strength and flexibility. If you need to give priority to a factor, please select the appropriate cable. In addition to voltage drop across wires and connectors, the only other tools required are stripping pliers and small flat-headed screwdrivers.



Step 2: Stripping the jacket.


Pick up the stripping pliers and rotate them around the external sheath to expose the internal wires inside the main quadruplex overhead wire (called conductors). A number of stripping pliers are suitable for a variety of AWG, so be sure to use the correct stripping pliers and do not cut too deep. If the cut is really deep and damaged the conductor, cut off the end of the electrical drop wire and try again.



Step 3: Stripping the conductors.


Next, use the stripping clamp to remove the sheath on the conductor and expose the metal core below.



Step 4: Preparing the banana plugs.


Unscrew the plastic shell from the banana plug by hand and put it aside. Then use a screwdriver to unscrew the fastener from the connector.



Step 5: Attaching the cable.


Insert the bare speaker triplex service wire into the plug and re-screw the fastener. The fastener holds the cable in place and also acts as a contact point between the rest of the banana plug and the speaker line itself. At last, screw the plastic case back to the connector and the cable can be used.
