martinw Posted November 17, 2011 Share Posted November 17, 2011 Picture link I have some confetti cannons fitted with this connector - does anyone know who makes it and where I can buy the mating part? Thanks Martin Link to comment Share on other sites More sharing options...
david.elsbury Posted November 17, 2011 Share Posted November 17, 2011 It looks like a figure-8 power connector.Do you have one to compare to?David Link to comment Share on other sites More sharing options...
martinw Posted November 17, 2011 Author Share Posted November 17, 2011 That would be a Telefunken power connector, but those have rounded corners, whereas this has sharp 90 degree edges. I see a lot of different connectors as part of my job, but I've never seen this before. M Link to comment Share on other sites More sharing options...
mutley Posted November 17, 2011 Share Posted November 17, 2011 It's not a standard fig-8 connector because it has flat edges with corners. Is the notch on both sides like a fig-8 or is it only on the one side to polarise it? (It's difficult to tell from the photo) It looks like it might be one of these.http://cpc.farnell.com/productimages/farnell/standard/CN0594206-40.jpg Link to comment Share on other sites More sharing options...
martinw Posted November 18, 2011 Author Share Posted November 18, 2011 Thanks Mutley That does indeed look like a very close match - I'll try and buy some sockets and see if they fit. Regards Martin Link to comment Share on other sites More sharing options...
slipstream Posted November 19, 2011 Share Posted November 19, 2011 If your playing with these - beware, we found them to be horribly unreliable - the power just melts a wire n string combo to release the gas - you can fire them on mains but sometimes they blow so fast they dont release, you need a decent amp 12v to be reliable and then you find they fire in 3 - 10 seconds - so can be iffy for a stage job when your used to pyro response times. If I recall, we found the plugs would fit into a standard figure8 connector with a bit of a trimming - and as it's 12v , I had no issue doing it Link to comment Share on other sites More sharing options...
Jivemaster Posted November 19, 2011 Share Posted November 19, 2011 I've heard of these being fired from 48v of sealed lead acid batteries, and probably 8+ AmpHour batteries too! This gets a big enough current pulse to fire them quickly, and remains low voltage. Link to comment Share on other sites More sharing options...
martinw Posted December 5, 2011 Author Share Posted December 5, 2011 Thanks for all the advice on this. I fired them from a 30V bench power supply with a 2A output limit (the supply goes straight into current limiting mode). This seemed to give a fairly consistent time of about 3 seconds between turning on the power and the cannon firing, which wasn't a problem for the show. I used 8 cannons and all fired correctly, so I would certainly recommend them and use them again. Martin Link to comment Share on other sites More sharing options...
