[Member-Forum] Motor Controller Ribbon Cable

[hank pronk]

Hi James,
The junction is just a strip with screws.  the reason for that is that you need to mechanically separate the wires.  You need to cut between the wires in the ribbon with a razor or similar.  The wires are so small and have a very small amount of insulation.  It is unlikely you will be able to separate the insulation equally between wires.  That is why the junction strip works.  You will end up with something that looks like guitar strings .  Then you need to pot the wires with epoxy or similar.   It is a bugger, but it works if your desperate.

Hi Guys, 
Kind of what i thought already.  Hank whats the junction box you talk about?  Is it something specific for ribbon cables? 

I wondered if there was some sort of vampire clamp to tap into the cable.  You get similar ones on computer ribbon cables. 
Thanks 
James

James, If you can't get to the business end of the ribbon cable it is possible cut and solder.  However this is a labor intensive approach as the cuts ends need to be prepped (stripped/cleaned such that they can be re soldered). It would be easier if you could have the cables on a bench surface but it looks like that isn't an easy option for your scenario.

Also it would be important to ensure no shorts so after ensuring the joints are good you could coat/secure it with some insulating material (epoxy?).

>>Trouble is that you cant undo the motor controler, or pot.  So you cant actually get to the start of end of the ribbon.  Well, not without breaking it open.
