Isolating DC jack

[rasco22862]

Hi, how can isolate this type of dc jack, from the enclosure in a safety way:


Thanks

In my experience it is a lot of trouble to insulate that type of DC jack from an enclosure, I had the same situation (I bought them without thinking about it) but I 'fixed' my problem by just buying new plastic ones (do not require insulation). It's just: if you try to insulate it with something, think about the fact that the isulation will wear and after some time it's possible that it doesn't insulate that much anymore: that's why I'd say to go for the 'safe' way to avoid problems and go with the plastic jacks

i cant get the plastic ones, here in Argentine.

Hmm, ... well actually I couldn't get them locally as well, but the guy in the store said he might be able to find a few in no longer used things he had lying around. I got back two days later and he had opened up some things and desoldered the plastic 9v jacks: maybe you can do the same with an old electronical device? If not: you can always order worldwide from Banzai I believe and as a final solution you could try to insulate the jack using rubber things: I've seen some people do it in the pictures thread I believe.

Rasco:
se consiguen las entradas de alimentacion tipo Boss, que son de plastico, en las casas de electronica  del centro
Solo que tenes que hacer un agujero en la caja que no es redondo, sino cuadrado en un extremo, y redondo en el otro  . (como una "D")
Mucha lima cola de raton.
Tampoco tiene rosca y tuerca, las tenes que pegar a la caja
Mas trabajo, pero funciona!

Just make the hole bigger and insert a rubber grommet. Like the one here:

   I isolated them in raco's, but..
 start with a big hole, enough to surround the jack with say 1/8'' or so, so it doesn't touch the sides.
 Work a hole into a piece of hardwood [I like to start with larger piece, then trim so I have someting to grab while drilling] about 1/4'' thick, get it so the threads will grab and make threads in the hole, maybe glue it in if necessary, I had to widen the hole past whatever drill bit I had that was close to get the threads to go all the way in 1/2 way easy.
 Drill 2 or 4 holes through the enclosure around the large DC jack hole, to mount the jack 'board' on, the wood insulates...mounted on the inside, with the jack centered, it looks pretty good, and comes out about flush.

I have isolated these by drilling a larger hole in the enclosure, and then mounting the jack in a piece of blank circuit board (you could also use something thin that insulates like formica or maybe thin plexiglas).  You then mount the board, with the jack centered in the larger hole, with two small screws to each side of the hole.  It takes a little longer to do, but is very rugged and works well.

Yes, you can do what petemoore and MKB recommended, but my idea works perfectly and it has a professional look.

I bought a bunch of these as well.  IMHO, there are two professional options that both have small drawbacks: 

1.  Drill the whole bigger and use a rubber gromaut (sp)... I've been doing this since I bought 10 of those, payed for them, I'm going to us em. 

2.  Reverse the positive and negative.  If you use a power brick to power your pedals, most come with a wire (sometimes with a red jack) that is for pedals with reverse polarity. 

Each have their drawbacks.  Next time, order some of the boss style plastic ones from smallbear.  I'm sure he'll ship em to ya!
