do flat psu socket's cable exist?

12345678

so this block is bothering me, I want something that does use less space

 

I thought into using a pcb to turn the connector in a better place

 

but I can't find something without those huge blocks, I wonder if they do even exist

so... you are looking for a "flat" 24 pin connector.... is that right? if so the don't exist, if not, I am confused, I'm not sure what you are asking exactly

I'm not really sure I understand your question. Do you want a cable without the connector? Or do you want your 24-pin to be 24 pins wide instead of 12 pins wide and 2 pins high?

No. Flat 24 pin PSU cables dosen't exist and no low profile connector exists

Flat, thin,... 24 pin cables don't exist. What could maybe work for you is a 90 degree connector if you want a little less bends.

 

HOWEVER make sure they are good quality as there have been some really cheap ones that caught fire before.

If you solder the 24pin wire directly to the board that would probably acheive the desired effect

The problem with what you want is that you need that height to hide the point where the sleeving is glued or heatshrinked to the cable. 

Also, each pin inside the connector has the bit that goes into the motherboard connector and a bit that crimps to the wire :

 

image.png.1803d6eed644b6abbece5f4b959769a7.pngThere needs to be that amount of height .. the first pair of "wings" crimps around the copper strands making very good connection, and the larger pair of "wings" crimps around the cable insulation and maybe sleeving, so that when you bend the cable or pull on the cable, you won't tear / break the actual copper strands and risk to do damage.

 

Lower height connectors would be possible if they change it to some sort of press-fit system where the cables would be "punch-down"-ed into the pins like they did with IDE cables and right angle SATA connectors. But, then you may not have the same amount of current carrying capability. 

 

One option you may have is to buy right angle adapters for the 24 pin connector. The connector that normally goes in the motherboard is soldered to a small PCB which also has the female 24 pin connector, so it's more like a very tiny extension. It's not that much shorter, but at least the cables don't go straight up, they're not horizontal to the motherboard.

Here's some examples

 

a bit uglier, you can see the pcb as they just put some tape or foam over it  : https://www.amazon.com/24Pin-female-adapter-desktop-supply/dp/B07BJ2QHM4

more professional looking, as it's nice plastic case, but much taller, kinda beats the purpose :  https://www.amazon.com/Cooler-Master-Degree-Adapter-Capacitor/dp/B07HZ6B6R1

not sure what's called that shorter version of the black plastic plug (the male one)

I've never seen one (in that form factor) for the 24 pin connector, but if you're really desperate, here are two solutions.

 

1) Desolder the connector, then solder the cable directly to the board, as Emosun suggested. You could also solder the cable to the BACK of the board (being mindful that you get the pinout right). I don't recommend this, since it's probably an 8 layer board with a lot of thermal mass. You'll need a vacuum desoldering tool (Hakko FR300 would work, but a Metcal DS1 would be a LOT better). I suspect if you try to do it with wick or a hand pump you'll trash the board.

 

2) Go on Mouser / Digikey and find the connectors you need (shouldn't be hard). You need a male and a female PCB-mount connector. This is BY FAR the hardest part, since these distributors have a massive number of different connectors in stock. Then you can lay out your own little board in KiCAD and have it made by a board house. The cost to have boards made in China is about $5 + shipping, and the quality is excellent. Soldering the connectors to the board is so easy that almost anyone can do it.

the problem is finding the connector

there are like thousands of different connectors

I'm not even sure what are specifically called the psu's connectors

 

some manufacturers do offer assemblying, but within their products/libraries such as jlcpcb

but not knowing wth those connectors are called, I can't either put em in a kitcad/altium drawing

They're a Molex connector of some sort, you might even be able to find it by googling since computer power supplies are so common. You may need to make a footprint yourself, though if you have the manufacturer's CAD drawings (which any useful connector datasheet will have) it only takes about 15 minutes. 

 

Don't have a PCB manufacturer do assembly on something like this unless you have 1000+ to do. This will be through-hole soldering, so they can't use their pick and place machines- that makes it expensive. It's also really easy to do yourself. Where the PCB assembly services by companies like JLCPCB are really nice is when you've got a whole bunch of boards with lots of small SMD parts on them. For example, nobody wants to solder 1000 SOT-23 transistors by hand.

I've spent a fair bit of time looking for a connector like that too, to make a 180 degree 24 pin connector/adapter, and never was able to find that type of connector. As far as I could tell, it's not actually a connector meant for connecting to a board, but instead is just a (custom?) cable connector that they mount flush to the pcb with very short wires.

Like mariushm said, that part of the connector is there to cover part of the pin that's crimped to the wire, so there's not much of an option unless you go with a completely different pin and connector configuration.

And unfortunately, those 90 and 180 pcb connectors usually have a much lower rated current capacity, so in case anyone is interested in them be sure to check that out first.

There should be a board-mount female connector, however. You might have to spend a fair bit of time with the Digi-Key parametric search engine, but I think it is likely that it exists.

Oh yeah, the female connectors are fairly easy to come by, I should have specified it's the male connectors that don't seem to exist.

I have seen female cable connectors, though.

the 24pin connector itself?

 

its called "mini fit" and produced by molex, i think you can order it in mouser, dont quote me on that though

FWIW the gender of a connector is determined by the contacts, NOT the connector housing. The standard PCB-mount molex connectors we are talking about are MALE, and the standard PSU cable connectors are FEMALE.
