|
|

hi
whats the official name of the 4 pin power connectors in the computers?
(what we use to power a CDrom or a hard disk)
some computer shops refer to this as LP-4 or molex connector, but with these names, i can not find it anywhere. (not even at Molex website) I just want to buy a connector (PCB type, female), not a cable.

It can be found at molex.com, the product name is Disk Drive Power. Related standards as ATA-x specification just provide a drawing, not a product name. ATX power connector would rather designate the MiniFitJr type connector interfacing the main board.
Also Tycoelectronics MATE-N-LOK series should contain suitable connectors. Most catalog suppliers, particularily for hobby electronics have parts in stock, I think. Cause they usually have a limited number of types, you'll may find it easier there as at a manufacturer.

| Yes, that's the 12V ATX supply MiniFit Jr connector) in contrast to the connector used to power a CDrom or a hard disk, as requested.

thanx.
these companies offer the same connector at different pitch sizes, obviously only one size can be used for existing hard drives. i will not to make a pc and make a hard drive for that, i want to use the standard connectors.
so, which pich is used for HDDs? 0.2 inch, 0.25 inch, 0.16734564564 inch?
i measured one with a ruler, its around 4mm. (the pin was unstable, so the pitch was 3...5mm.)
these mechanical drawings are so bad... its impossible to figure it out if its male or female, of course the product pages dont mention this negligible detail...

Do you want the connector that comes from the computer's power supply, or the mating connector on the drive's PCB? Those documents specify the AMP 1-480424-0 shell and AMP 61314-1 contacts (or equivalent). That's the connector coming from the power supply:
http://catalog.tycoelectronics.com/TE/bin/TE.Connect?C=1&M=BYPN&TCPN=1-480424-0&RQPN=1-480424-0
If you want the drive's PCB connector, try clicking "mating products" on that page.
Connector manufacturers usually don't use the terms 'male' and 'female' because many connectors have interchangeable pin types or the shells have opposite type from the pins, so the terms can be confusing.

ok.
the connector which hangs usually at the end of the power cable, what we plug into a hard drive:
i want that one as a PCB solderable version. so I want to solder it onto a PCB instead of a wire.
(so NOT that one soldered onto a HDD)
Added after 1 minutes:
isnt that 0.156 inch pitch?
your link shows a 0.2 inch pitch connector, obviously these are not compatible

These connectors have 0.200 inch pitch, not 0.156.
Go to the Tyco link shown in my previous message. Under the catalog section, click on "SOFT SHELL PIN AND SOCKET CONNECTORS" to download a PDF of various styles of this connector, including PCB mount.
Shopping for connectors can be tedious and time consuming. Good luck.

i checked those, they say 0.2 inch on the websites.
but i have measured one (which is hanging on the ATX powersupplies) and it was much less than 0.2 inch, around 4mm, which is 0.156inch.
maybe tyco wants to sell it for computers, but they dont use it.
I dont know...

Yes. there is a connector with 0.156" spacing, that's the ATX auxilary 12V-connector I mentioned in previous posting, but it isn't used for hard or floppy drives. I think, the two types a hardly to mix-up, cause the harddisk or "peripheral power" connector is one row, 4 positions and the ATX auxilary power has 2 rows.
To my opinion, enough references have been given in this thread to loacte the correct connector.

-yes its used for them, what i measured it was on a SATA cable, for hard disk power input.
"To my opinion, enough references have been given in this thread to loacte the correct connector. "
-I dont agree, its still not clear for me... (dont think that i am stupid!)

OK, you possibly could mention, that you have been talking of a wire-to-wire connector on a SATA cable. If I may remember the original question:
| Quote: |
| whats the official name of the 4 pin power connectors in the computers? (what we use to power a CDrom or a hard disk) |
I don't hear of a SATA connector here.
Furthermore, the SATA power connector always needs 5V for 3.5" drives and additionally 12V for 5.25" drives. 3.3V should be present, but are not used by todays drives. So if a SATA power connector is connected through an adapter, the said 0.2" old-fashioned peripheral power connector would be used in most cases.
Some manufacturers have their own connectors for adapters, but they are not standarized, as far as I know. Could be, that you are facing such a manufacturer-private connector.
P.S.: For further clarification: Has your connector one or two rows? Which colours are used for the four wires?

what i mentioned is a cable: one end is a sata connector, going into the ahrds disks sata connector, the other end is a 4pin connector.
although in the sata specs they require 3.3v, the HDD manufacturers dont, so thats why its so popular to sell cables without 3.3v.
one row, white, 4 pin. colours: 12V, 5V, and 2 grounds.

The only standarized PC connector of this kind is the said 0.2" peripheral connector as shown below. This types are generally available from catalog distributors. If I understand right, you're searching for PCB socket type connector. The AMP 770997-1 and similar types should fit, but may be difficult to get.
P.S.: I was incorrect regarding the MiniFit Jr. 2x2 pin ATX connector, it's 1.65" (4.2 mm) rather than 1.56" (3.96 mm).

what i am looking for is a mix of the firs 2 pictures among the above 3 pictures: pcb mountable, right angle, but socket and not pin. maybe it doesnt exist.
i dont understand if all manufacturers make it as 0.2 inch, then why did i measured 4 milimetrers (0.156 inch) instead of 5mm (0.2 inch)?
i will check it next working day again, on more connectors in the lab. (tuesday)
is it possible that the 0.2 inch is not the pitch, but the distance between the pin-centerline and the edge of the connector?

The shown connectors have a distance of 0.6" (15.24 mm) between the outermost pins/sockets, very clearly. Of course, a different connector may be used with your power supply, but then it's non-standard.
A right-angle PCB socket header isn't available from AMP according to the catalog, only vertical version exists. Other manufacturers have smaller type variety than AMP/Tyco, as far as I've seen.
