Deans ultra connectors

[olmod]

Probably the most widely used and accepted battery connector is being copied:eek: ,the only problems are complaints on how tight the origonals are,well there are some good tips to help this ,a light dusting of graphite dust;) ,burning with the tip of a hot iron around the sides to form a rough groove;) ,drilling holes through them and tying a piece of cord to form loops :) , but back to the imitations a few problems are being noted , some have a burr on the spring that scrapes of the gold plating while being used:eek: another type(black) fit themselves ok and so long as they are used throughout you whole system thats ok :) but they will not mate to the genuine ultra,the thickness of the male tags is too thin and if you had a pack with genuine ultra female on and tried to plug the copied male into it you would find its to loose and you will lose power:( . cheers Lez.:)

OK, here's a basic question: What's the proper wiring (polarity) of these connectors? I could not find a standard ...

doh ... your other post wrt a basic ammeter (assuming BLK = Gnd & RED = B+) just answered my question!

Thanks.

On both male and female Dean's connectors, the polarity is clearly marked
and, IIRC, the Dean's copies too!

I used to have a horrible time getting deans Ultra connector appart after I soldered them. I learned to hate them. I got a tip to use the other end (male or female depending) to plug in to the one that I was soldering. Turned out that I was getting them too hot and it was shifting the connectors within the plugs themselves. Using the mating end and being concious of how much heat I was using helped tremendously. They are as easy to get apart as JST connectors now :)

Yeah I used to have hard time to and dad read somewhere about using the soldering gun to put grooves into them and now its easy to get lose.when there brand new tho they still are to get un done there tight.

Good tip Mike. I'll have to try it next time I solder a couple. :)

I have never had a problem in unmating the Dean's plugs but I always do as Mike suggests above, always mate the mating half prior to soldering. This prevents missalignment due to heat. Use a big enough iron, pretin, get the heat on quickly by using the proper (at least 40 watt, preferably larger) size iron and then get off.

I have a hard time keeping the shrink wrap on them. After some use I find the shrink wrap pulls off the connector and slides down the wire. Even making sure that it is up tight against the connector when I shrink it doesn't seem to help. It appears to depend on the solder joint itself as to the type of surface it has to grab onto.

I've never tried it but maybe a drop of CA wicked under the heat shrink (end away from connection) before shrinking would help. :)

The keys to using Dean's Ultra connectors is partly as mentioned above, partly what follows.

First, everything must be clean. Second, tin the terminals first using flux, second using only enough solder to coat the terminal. Too much solder is bad. next, tin the wire end. You can plug the pair of connectors together if you like but it's not really needed if you are doing as I suggest. Next, hold the wire firmly against the tinned terminal on the connector. Place your iron on the other side of the terminal from the wire. Be sure to hold the iron so as much of the tip is flush against the terminal as possible allowing the most heat to move to the terminal quickly. Watch the solder melt and flow between the terminal and the wire. once that occurs remove the soldering iron and hold the wire still until the solder cools. You should be able to see the solder solidify.

A couple of points that are very important. As I mentioned everything must be clean including the tip of the soldering iron. Next, as before more solder is bad. If you've done the job right you should not have to add any solder to the connection when you heat them up to join them.

As for the shrink coming off it sounds like you have too much solder on them.

I am new at this, but I use a heat gun to shrink the tubing. I have no problem.
