Title: Connectors
Post by: The long Build on October 05, 2011, 10:15:31 PM
There now seem to be a few type of connectors available, I,m sure there are many, many others, however the ones I am looking at are

The Tamiya type

Bullet type

Deans connectors (new one to me)

What do people prefer ? and Why..

I used to always use the Tamiya ones but tend to start getting connection problems after regular use, also when hands cold very hard to undo, have started to use the Bullet type, but have now seen these deans connectors and just wondered what the advantages each had over the other.

The Deans Connectors have a good surface area in contact so can carry a higher current.
The way the pins are arranged ensures you cant connect any way but the correct way.
BUT
If fitting these do not leave the soldering iron on when soldering the wires on the contacts as the heat can melt the body.

I converted to Deans, as you can only connect one way (on some connectors you can push worn plugs together the wrong way) they also take High ish amps, the gold bullet can take more, they can be very stiff to push in and out, there are a lot of cheap coppies  I try to buy in bulk from the same place and they tend to fit together better, I tend to be involved with boats that the connectors need to pass a bit of current.
the deans don't seem to tarnish the way tamiya or the amp connectors do that are just pressed steel.

have a play with a pair of deans before you decide to convert over as they are not to everyones liking.

I have a block for soldering Deans connectors from the states , you need a very big iron and work very quick, plus I find if insert  the one you are soldering in to a spareplug they tend not to deform

Must admit when looking at the deans I was not / still am not quite sure how to go about it..

HS93.. You say you have a block , how does that work. Any links to any pictures of said item.  Also intrigued that you say the bullets can take more amps, as one of or members recons its the deans that can take more ?.

Jiant Cod do some nice deans connectors made out out of decent plastic  plus they have grips on, when soldering clean terminal part to be solderd with a smal lrotary grinder, then use baker fluid and wash after dont forget to put heat shrink on first , ( I put two pieces on each and use the glued type) as they will have a lot of pulling in there life.

Peter,

Was looking at one of these if suitable/similar to what you use.

The latest version of these Ultra Dean type plugs are now pre-coated with flux and can be soldered without any preparation.

I have now changed the connections to these in all my boats and have no problems at all.  Component shop offer batteries with Deans type connectors already fitted at no extra cost.

Some of the cheap clone deans can be a lttle difficult to connect, diconnect owing to the smooth surface.  This is compounded on model boats if you have wet hands.

I engrave a couple of grooves on mine to give a better grip

These ones are quite popular as well

I have standardised on Deans connectors in all my boats because, as both Shipmate60 and HS93 said, they are virtually foolproof as they can only be connected one way. I have organised it so that any motor and any ESC can be used in any boat, as the wiring is the same polarity throughout my (small) fleet.

I hold the connector in a vice while soldering wires to the tags.
