Connectors - Any idea what these are called and where I can get them from?

[Chris Walby]

Attached to the other end of my retract. Either male & female plugs or extension leads don't mind, just need half a dozen. 

 

Ps the look like a normal servo plug, but two wires only 

 

Thanks in advance

Looks like a JST plug found on small lipos.

Hi Chris,

 

It's a JST BEC connector.

It does look like just a 2-way version of a standard servo plug. A JST power connector has chamfered corners on one side and a groove down the middle on the same side so it is polarised.

It should plug into a standard servo extension lead, just need to take care with the polarisation.

This kit has housings. The crimps aren't particularly high quality, so I would suggest taking the wires out of a servo extension and moving them over.

Thanks guys, yes its a JST....Mike I did think of that until I get to the retract controller and then the std servo plug won't fit....

 

PS I really don't like making these up so just buy the ones with a short lead and then inline solder/heat shrink sleeve.

I still cannot see any chamfers or grooves in that connector. I assume you problem at the retract controller is it only has a 2-way socket so a servo extension won't plug in.

My suggestion then is to swap the existing 2-way housing for a 3-way housing from a servo extension lead, and put the 2-way housing on the end of the extension.

Look at the existing plug and you can see 2 tabs that are retaining the crimps in the housing. Using a pin, gently lift each tab up and pull the crimp out. Repeat this with the plug on the end of the extension. Then just push the crimps into the "other" housings.

I think these are DuPont connectors - I've just bought a kit of them - it wasn't much more to buy a kit than the few individual ones that I wanted.

 

They are common in electronics and computing.  They are similar but not the same as the JST plugs which have chamfered edges (making them polarised - you can only plug them in one way) where these are squared.

 

I bought these

Do you have a crimp tool or do you need them with leads already attached.  By the way the male connectors come in two guises either as a header strip (which isn't in that kit) which would typically be soldered to a PCB but can be connected to wires, or as plug similar to what is in your photo but with pins sticking out (they are in the kit - using the same plastic housing as used for the female connectors).

 

Cheers,

 

Nigel
