ADC Punch Tool..?

S

spinjector

In a few places around here, we have those ADC punch blocks with the round split terminal in the center surrounded by a red, black, or white plastic shroud.

Hate them.

But I need a punch tool. Does anyone know where one can be had for cheap?

Or even what that style of punchblock is called? I don't eve know.

Thanks.
 
Omg. It's only $87..! That's wayyy better than I thought it would be. Almost cheap enough to get two. Ok, well maybe not.

Thanks. =-)
 
Corrosion blocks! Noise generators! Blistering barnacle semi-conducting #@&%! junctions detecting RF and rectifying! Arghh!

Sorry. Had to get that off my chest.

Put in a great big panel with screw terminals. Anything that's supposed to bite through insulation won't do a good enough job.
Anything that's not supposed to, will. Shortcuts make headaches. Punch panels are only designd to make things quick,
they are NOT the best way to do things. Ditto with cheeze-whiz connectors.
Twisting two wires together with MASKING tape insulation gives a lower ohmic connenction than a punch-block,
and it won't corrode (or oxide ) up in 10 years to bite you in the b*tt.
Well, the tape wiil fall off, etc, but I cannot say enough bad about punch blocks thank you.
 
Tom, personally I agree. I think punchblocks are the biggest bullshoot in radio engineering ever. Well - except for HD Radio... ;-)

I've often pondered the ways I would design a facility if I ever got the chance, and one of the things I would do different is there would be NO PUNCHBLOCKS. Oh and while I'm at it - NO ZIPTIES either. =-)
 
Back before the crash of the economy, when I worked for a big Entercom cluster and we had six engineers and could concentrate on projects, I set myself to the task of hunting down all the bad punches on the Sierra AS 64000 router and a 32000 router. 256 channels in & 256 channels out, and I forget the other, with 28 studios including the edit/news cubicles. It took days, but I got back about a dozen bad lines, which we needed badly.
 
Raise your hand if you've ever re-punched the jumpes on the back side of an ADC.
Or get a heat gun too close and melt the plastic.

Really haven't had any trouble with the old 66 blocks. Have hundreds of them (sigh).
The few problems were all sloppy installation.

But we don't have high humidity here.
 
Our biggest problem was, putting three wires in a single punch (such as half-normalling across). If you have three wires, the center one won't always make good contact.
We had to replace them all with ones where the normals were soldered internally.

:D The center one ALWAYS won't make contact! And ususally the upper one's not good for long either.
