A female banana connector (banana
jack) is a single-wire (one conductor) electrical connector used for joining
wires to equipment.
The banana jack that is usually
mounted on equipment is a 4mm socket for banana plugs about 25 mm (one inch)
long and 4 mm in diameter. An electric contact is made when the banana plug is
inserted into the front hole of a banana jack. The back end of a banana jack has
a contact plate for connection to the internal wiring of a device. The banana
jacks usually have an insulating color-coded plastic cover.
|Long Banana Jack
Long Banana Jack is a panel-mount socket
for 4mm banana plugs with up to 20 mm (1 inch) long pin. Can be mounted
on metal surfaces with up to 2 mm, and plastic or wood surfaces with up
to 5 mm thickness. It mounts on a 8mm hole. The overall length is 25 mm.
(Price and Availability)
The socket hole in long banana plugs is closed
at the bottom end. There is also a smaller hole on the back end. Internal wiring
may be achieved in two different ways. You may insert the internal wire into the
back hole and crimp it using a crimp tool or locking pliers. Alternatively you
may place the wire between the two internal nuts and tighten the connection by
turning the nuts so that the wire will be clamped between the two nuts.
|Short Banana Jack
Short banana jack is a panel-mount socket
for 4mm banana plugs with any length. Can be mounted on metal surfaces
with up to 1 mm, and plastic or wood surfaces with up to 4 mm thickness.
It mounts on a 8mm hole. The overall length is 13 mm. The face outer
diameter is 11 mm.
The socket hole in short banana plugs is open
ended, that is why it can receive any length banana jack. Internal connection is
made by soldering to a tin plated pierced lug terminal.
