Re: Another shout for help, please - plugs/connectors
« on: November 28, 2021, 09:42:29 am »

My request this time concerns the orientation of M/F plugs/connectors on model wiring. Is there a convention to follow?
Starting where?
My outboard has Male bullets obviously to connect to Female on the next wires. Would it then follow that at the other end of those wires would be a Male leading to Females on the ESC? Would the same apply to the Battery connections?
Needing this information to sort out my Riva type setup in the correct way as it's a bit of a mash up caused by inexperience/unavailability of parts and using kit I already have.


Thanks again in advance.

It all starts from the battery. This should have 'female' i.e. shrouded connectors to prevent accidental short circuits. Moving on from this point, the following connectors define themselves as male or female to ensure the powered connector is always similarly protected.

Thanks barrie, I think I understand that the M/F designation concerns the orientation of the actual terminal not the housing?

Yes the m/f designation is the actual metal connection.
Shrouded conenctors, as om says, are always a very good idea.

Yes I tried to make this clear in when writing my post, but deleted the text because I couldn't find the right way to describe what I meant. %)  Forget the housing, its the metal that matters O0

Thank you so far, so to be clear the same scenario carries on from tho outboard Male bullets?

Think of the power outlets in your home - you always plug male into female. Its the same in your model - doesn't matter if the 'power' outlet is the battery or the Speed Control - male into female.

Thank you barrie, I am obviously looking for something that doesn't exist. (as usual)

I used to go for insulated female connectors on the + side of the battery and males on the -ve side. The reason is to avoid the risk of accidental reverse polarity connections damaging the ESC. With this arrangement it is possible to plug the battery into itself, so the fly leads are cut to a length so that they cannot physically connect together. Now I tend to use a dual conductor connector such as the Deans T plug with females on the power source side and males on the load.

Now I tend to use a dual conductor connector such as the Deans T plug with females on the power source side and males on the load.
In most model setups, plugs are twins - from the battery, one lead going to a two pole line socket that is polarised so it can't be connected in reverse (unless it was wired that way by the user).  Similarly with the ESC power plug.  ESC outputs and motor leads are often bullet connectors on separate leads to make life easier when it is discovered that the motor is turning the wrong way.  Most batteries came with a Tamiya connector, nowadays a greater choice of better ones is available ready fitted.  Care is obviously needed if changing from Tamiya to something better to ensure that the right wire goes to the right pin.
Red for positive with black for negative is almost universal.  Having blue and yellow for the motor output leads is nice - ESC makers who insist on using red and black for their motor leads deserve to be roundly cursed.


SLA are a case where great care is needed - it is very easy to get the pos and neg reversed as they are almost identical tags, the only indication being the red dot by the pos terminal, which might have a symbol moulded in nearby.

A picture may be worth a thousand words! See Fastelectrics post! I use these ones and choose which size to suit the job. :-))

I have always understood that the XT60 connector with the pins inside is the MALE and the insert with the sockets is the FEMALE.

That is generally taken as the standard but the manufacturers of the XT connectors call them the opposite. They use the outer casing to determine the gender of the plug while most others use the plug or socket to determine it. Most use the sockets for the battery connector as they are fully shrouded and less likely to be shorted by a piece of metal.

on connectors like deans, there is also correct orientation regarding which is positive and which is negative pole.  on "real" deans connectors, there are little + and - molded into the plastic.

The XT60 and 90 connectors also have the polarity moulded into the plastic casings.

Just waiting now for the postal service.


Nail biting tomorrow as the drill comes out.



Huge thanks to Stan for the info and conversations.

Hi good luck with the adhesives we discussed and hope all goes well with electric side of things.
