hi all, I am trying to find the best way to connect led strips

hi all, I am trying to find the best way to connect led strips to an arduino or breadboard, and at the moment, the only way is to solder some cables, to pins but I find that really unstable…I am trying to find cheap 3pin pcb connectors to led, but I can only find 4pins, like these http://www.ebay.fr/itm/351016837417 (see the right one on the thumbnail below, or the one with Black/Blue/Red/Green cables) whereas I am looking for 3pins (for WS2811). Can any of you recommend a nice tip or share what you are using ? thanks a lot !!

I use ones similar to these (4 pin JST), you can get 3 pins as well:

I would suggest these…

Personally, I use the same type but in 4 pins version. They are very small but surprisingly robust. You will need a special crimper to terminate the wires: Model SN-01BM
