Dual linked banana plugs?

What would one use these for?

Re: Dual linked banana plugs?
Good evening,
I have seen similar links used for bench or lab type power supplies. They are for the option of mains earthing a floating DC output or for linking the voltage/current sense feedback connections on a stabilised power supply. Christopher Capener |

If they are 19mm spacing they can be used for shorting the input terminals on multimeters to show any deviation from zero on ohms range before calibration.

I've seen similar jumpers but 1/4" jacks for patching on a patch bay,maybe these had a similar function as there are quite a few of them? They look bespoke and well made.

We used versions of those on breakout boxes. You unplug a control module from the wiring, and put the breakout box and leads between the CM and wiring. All wires run to a pair of 4mm sockets, with one of these bridges or jumpers linking the two sides together. You can then easily probe each line, or pull out the jumper and probe either side, or inject other signals. That way you can fault find the system, check out behaviour under fault conditions and so on.
EDIT: This is what we used: https://uk.rs-online.com/web/p/banan...ctors/4321705/ |

duncan- similar to what we used in GPO TRS ,with output in centre on audio panels to give us a test point on ( usually) OB circuits.

I use insulated versions of these links to set output voltage, earth connections, etc on an isolation transformer, see photos.

4mm for the plug is a hard metric size... I can't see the standard spacing for the twin version being 19.05mm rather than 19mm. They also exist in twin-4mm to BNC. When I have laid out a panel, I've always used 19mm. However, as the difference between 19mm and 3/4" is only 0.05mm, I might have been wrong, and just got away with it. I'd love to know! |
