MB6582 Base to CS connection

Recommended Posts

Hey all,

I'm a big-time lurker, low post-count kind of guy, so you've probably not seen much of me. Greetings!

I'm also lazy when it comes to connecting circuit boards together. So...

I was wondering if there was anyone out there looking for an alternative to all the ribbon cable

business (ie. cutting, stripping, bleeding) and would be interested in something more befitting a lazy person

such as myself, like pre-cut FFC with solder tabs:

I'm open to ideas, thoughts, comments, and would be willing to organize a bulk order

should enough people prove interested.

You can also tell me to stuff it and I will gladly pick up my XActo knife and go home.  ;)

-Tristan

looooooong.  Stupid long.  5" or something like that.  And I got them with female SIP on one end to mate with a right-angle header I put on the CS board.  You probably want 2".  If memory serves, I bought 10x 8-conductor (made sense with the price break) and 1x 2-conductor.

I've just been too lazy to do anything about it.  But forget about stripping those little ribbons.  They are the length that they are.

Resurrecting this thread... The connection between Baseboard and CS makes me a lot of headache.

The 100mil spacing ribbon cable (Part Number: 606162-F0) from Conrad is no longer available (discontinued summer 2012). As a replacement Conrad proposed a different cable (607378-62). I've tried this without success. This is not the stiff solid wire! It's stranded wire (see first picture) which won't give a strong connection (wire breaks between the soldered connection and the insulation) and it's a pain to remove the insulation without partly destroying individual wires...

Then I found bunches of jumper cables at ebay (search for "Dupont cable" or "jumper wire"). They are 20cm in lenght and crimped to a 1-pin female header at each side (see third picture). The cable itself is AWG26. My idea was to cut it to a short lenght and solder one end to the baseboard. At the other end I pulled the crimped connector out of the housing and pushed it into 8-pin SIL housings (Mouser Part Number: 855-M20-1060800), see picture 4. Looks good, but same problem here: Seems to break easily at the soldered end. :(

Of course I found other threads with different solutions (from Bugfight; the superb guide from Hawkeye...). The Reichelt PSK 254/8W connectors for example (see picture 2) seems feasible, but the cable here is thicker (AWG24 compared to AWG26 above). I tried them (like others did sucessfully) but they are to stiff in my opinion and it's to hard to close the case.

As I couldn't found 100mil ribbon cable (solid wire) in Germany at the moment I might go shopping at Mouser again...

After searching for hours and days I came to another idea (and this thread): FFC - Flexible flat cable. So far I found a couple of vendors (like here) but no supplier which sell FFC cables as long with the proper LIF or ZIF connectors in small quantities. That's why I'm asking for here. :smile:

Hey there :smile:

 

While this does not answer your original question regarding the flexible wire - and also it may not be the most elegant solution, you can always fold the thicker and stiff wires at an 180° angle "in the middle" of the MB6582 case, thus allowing for very easy opening and closing of the box. I opened the case multiple times since 2010 and all is good:

My advice:  Bite the bullet and just cut all the jumpers to length by hand and make sure you use 24 ga wire with FLEXIBLE insulation (i.e. NOT TEFLON), it takes a while but down the road it will save you a TON of time.  The 0.1" ribbon is a pain to strip and if you break any of those leads, you have to make a new one and take out the old on to fix it (had to do that twice) which is a long and painful operation.  With single wires, if anything goes bad, its ONE wire to replace

I can second that. I have the flexible ribbon cable in my machine, but it was a long and painful process. Things usually go wrong at the last lead in the ribbon cable, i.e. I broke a lot of wires when trying to remove the insulation of the last lead in the ribbon cable...

I am at this stage in building my MB 6582 but can't seem to source a good quality cable for the control surface to main board connection. I prefer to deal with Mouser or Digikey if I can. I did find one suitable cable on Mouser, but instead of 8 individual wire strands the cable had 4 pairs of 2 wires. Doesn't sound like the right kind of cable for this project.

 

Anyone have some recommendation for connector cable from Mouser or Digitech? Ebay?
