What are these connectors called?

[Robin GrahamParticipant @robingraham42208]

I have a project which would be easier if I could use in line connectors like this:

I've tried various search terms, but failed to find them so far. Ideally I'd like single, two, three and four way connectors which can be connected to the wires without any more specialised equipment than a crimping tool or soldering iron.

Can anyone help?

Robin.

The round pin "Molex" connections come in multiple sockets. click on the link Molex

Do a search for JST connectors.

[Paul LousickParticipant @paullousick59116]

Electronic part suppliers should have them. We have local shops called Jaycar and I believe that they are in the UK as well.

Oops, just noticed the red arrow pointing to the off board connector. I was looking at the PCB. If you want an incredibly simple in line connector, how about a straight through WAGO style connector?

3M Scotchlok are a recipe for disaster ! To the best of my knowledge they are only made to piggy back one wire onto another, the connector is made for a given size of conductor – wire small = poor connection and wire to big cuts conductor that then breaks. They have kept many auto electricians in a job ! Noel.

Hmm, Scotchloks, IDC (Insulation Displacement Connector) as stated. a pain for auto electrical quick connections. Strangely enough, a smaller versions favoured by the telecoms companies for both internal socket and external extension connection.

For this sort of application (depending on the current capacity) I use automotive connectors,

The component indicated in the photo. doesn't look like any Scotchloc that I've used. Seems to be the male half of a 2-pin connector, but I don't know the spec.

The telecom ones are usually called Jelly Crimps,(they're full of a gel) , commonly 2 or 3 way and should only be used on single core cable as they will shred stranded cores.. I used loads of them when I wired track power droppers all over an OO layout with no problems.

Have you tried the Component Shop. https://www.componentshop.co.uk/leads/connectors.html?p=8

+1 for JST connector.
Theise need specail crimp tools.
An alternative is 0.1" pithch headers. The Amercans call them "dupont" Connectors. Try a seach on your favoite online market for dupont connector kit

The type pictured by Robin might be an XH connector.

I like Powerpole Connectors and posted about them about halfway down this forum page. They're a bit clunky though for light electronic work.

Thanks for replies – all very helpful. I should have been more explicit perhaps – what I'm looking for is the in line type of connector pointed to by the red arrow. The board in the pic is the 'brain' of a toy pony – the various wires bring in signals from sensors on the toy's body and actuate motors which move the head etc. My task is to remount the sensors and motors in a much bigger frame for a theatrical prop, so I need to extent the wires.

Following the links it looks like JST connectors are intended only for PCB headers rather than in – line? It looks like automotive connectors are the things I want. I can get a box of 40 assorted from Amazon for a tenner – probably pretty flimsy compared to the more expensive connectors suggested in some replies, but will do the job for what I want I daresay. The thing is powered by six D batteries, so max 9V and not much current I guess.

Thanks again, Robin.

I probably shouldn't suggest this, even though the connector is vaguely familiar, but:-

15W Antex with 60/40 solder.

 

I'll get my coat…

Eee, there's always one . Fair point though! The thing is that the 'creatives' who have asked me to make the prop don't really have a clear idea of what they actually want yet. I'll come up with something, they'll say 'Great, but could you change the place where you pat it to make the head nod'. It's an iterative process. So I'm trying to make my design as modular as possible. Hence the desire for connectors rather than soldering.

Dave – thanks for the link to Powerpole connectors. They might well be useful for something else, but probably overkill for this project.

Robin.

Would this be the variety that you need?

[Robin GrahamParticipant @robingraham42208]

Well, this has been an eye-opener. I bought a box of connectors (DuPont and JST) together with a new crimping tool which works with both. £35. But not quite right for what I wanted to do or the wire gauges I had to work with. So I investigated further. JST have a range, according to their website, of more than 30,000 styles. Then there's Molex and others. The right things must be out there, but this rabbit hole is too deep for me.

I shall resort to the trusty soldering iron as Mark advised, and heat shrink.

Thanks for all the advice though – it's been an interesting journey into the weird world of electrical connectors.

.

For what you appear to be doing, Robin … I think Robert’s alternative would be ideal.

Widely used on Arduino projects, and readily available
