Multimeter Banana Plugs

The second banana plug on one of my multimeters failed, so I finally got around to replacing them with a dual plug from the Drawer o’ Banana Stuff:

Dual banana plug - assembled
Dual banana plug – assembled

The bulky test leads don’t quite fit through the convenient retaining ring, so the zip tie holds ’em in place.

A setscrew at the base of each banana jack tunnel crunches the test lead wire against the plug base, but, alone among the collection, this plug had one missing screw. Rather than toss it away (or, worse, back in the Drawer), I decided to Solve The Problem once and for ever:

Dual banana plug - improvised clamp screw
Dual banana plug – improvised clamp screw

That’s an ordinary M3 screw from the Drawer o’ Random M3 Stuff with its head hacksawed off, a slot crudely hacksawed slightly off-center into the end, then lightly filed to hide the worst damage. With a bit of luck, nobody will ever notice it …

    1. Got it in one!

      Well, OK, I tried running the black lead under the ring, but it didn’t cooperate.

  1. The second banana plug on one of my multimeters failed,

    I feel cheated by fact that “second” is not a hyperlink leading down the rabbit hole that is this blog :)
    There is still hope you somehow forgot to make it a link though :)

    1. The original “banana plugs” had metal posts split into bent-outward quadrants. Unsurprisingly, the metal wasn’t springy, so the quadrants gradually bent inward and eventually broke off. When the second quadrant in one plug broke, I chopped off both plugs, tossed ’em in the trash, installed the dual plug, took out the trash, then wrote it up.

      That’s the story and I’m sticking with it.

      I’m sure there’s another set of those craptastic test leads disintegrating in another meter. They’ll get a backlink to this story, fer shure!

      1. Very well, I’ll let this one slide, though it brings “dog ate my homework” excuse to mind :P
