PCB connector confusion

Wed Jul 25, 2018 5:59 pm

I am adapting an 18v DC supply for a project and it comes with 240v AC input and 18v DC output but I don't recognise the board connectors. I managed to find the male pins on ebay but cant find the female version to connect my wiring? Pins are approx 5mm pitch and are square 1.17mm x 1.17mm x 11mm high.
Any ideas?

Do you know what device this power supply is from? It looks like it came out of something else and knowing what it was would help a bit.

Those headers are quite common in products I have dismantled. Unfortunately I have no idea what they are called. I usually just use the connectors cut off whatever they used to connect to.

You can always unsolder the pins, replace them with screw terminal blocks, or solder on flying wires to choc-block.

They used to be known as "Molex" connectors, but Molex manufactures a wide range of connectors now, and this format is an industry standard.
You can buy "Molex PCB connector housings" and "Molex PCB connector contacts" separately, the contacts crimp or solder to individual wires and are then pushed into the housing.
Since you are on Zarg I don't know what supplier to recommend, delivery charges could be astronomical :o :shock: (HINT: set your location to something more useful if you want sensible help.)

I only know molex as the old round pin connectors, usually in computers for connecting drives. These are square and a little smaller. Without a reference I'm finding it really hard to find the right thing!
Oh and in my case Zarg is currently in Brexitland!

No idea what it is from, but it is a standard JY-72-18 PSU.

If the pitch is correct they should be interchangable. Look up Molex at CPC or RS.
And yes, Brexitland deserves to be called Zarg.

Here ya go: https://www.overclock.net/forum/31-powe ... mbers.html has a listing of connector part numbers and https://www.digikey.com/product-detail/ ... ND/3160341 has drawings.

I thought they looked familiar. Molex MiniFit Jr. series. You can chase down the part #'s listed in the first link, and if you dig around you'll find the drawings in the second link and that should lead you to what you need.
