Topic: Correct headers for 0.1" heavy duty pins (Read 915 times) previous topic - next topic

So I bought a few larger displays from Futurlec a while ago and now I am going to drive these suckers (MAX7219 to the rescue).  But like my other projects, I want to put them into headers rather than making a permanent solder connection.  Here are the displays:

The pins are on a 0.2" spacing and fall fine into the normal 0.1" spacing, they just skip every other space.  The header I generally use is this one:

It's just too snug for this display's pins.  The pins push the header pins out of the header body.

Does anyone know of a similar header that is looser, more play, whatever the term would be?  Or any other idea for less-than-permanent mounting for these displays?  Thank you!

What is the diameter of the pins? The drawing does not seem to say.

Yeah, that is part of the problem.  I can't find a datasheet that says exactly.  When I bought them, I had no idea there was a difference, it doesn't say anywhere.  On the other hand, these are really nice displays and I have breadboarded them successfully so no complaints.  I don't have a micrometer that I could measure this sort of thing with.  All I can say is probably double the width of a normal pin on an LED display.  They are nice, stiff, and strong.  I could take a macro picture and post it if that would help.  But if anyone has an idea of a header that is useful for this sort of thing, I would be only too willing to buy a couple to try them out and if it doesn't work out I will not "blame" anyone.  I am only too willing to experiment.

Well standard male IDE header pins are .025" X .025" square with 'filed' points to aid insertion into female IDE sockets pins, but if you don't have a micrometer or other means to accurately measure what you have I don't know what to tell you to do?

I was just sort of hoping someone had trouble similar to this before and could recommend a header that is larger and looser, probably 50% so in each dimension.  I am willing to buy a few, eat the shipping, just to try them out.

Sounds like its time to add a new tool to the tool kit

Maybe discrete pins and wire up a cable?

Ha, I love Harbor Freight and there is one nearby and that is where I got my compressor and extra air tanks, but I have never considered them for precision tools.

I have found some headers that are 0.2" (5.08mm) by design and I think they take the heavier pins.  I am going to try to sample a few and if they work I will buy some.

Going to see if they have these calipers at the local shop.

Maybe something from JST

In regards "anyone has an idea", if you look through the digikey or mouser
catalogs, you'll find 200-300 pages of headers and connectors.
