It is quite small to sneak inside and it will not damage the plastic housing or the pin itself. I find the 1mm flat screwdriver to be just the tool for the job.

Your life will be easier if you provide yourself a really small screwdriver. Before i discover the trick, i thought that it was 3 or 4 levels above. Obviously, this grip needs to be restored.Įxtracting the pins from 4-pin power supply Molex connectors Please try to save yourself from injuries. First, i pull the grip out with the edge of the blade, and then i straighten it with my finger.

When the pin is extracted, the grip probably needs to be restored. With a little practice, you will get the feeling. The force required to push the grip down is significantly less than the force to push the pin out of the housing. Try not to cannibalize the grip of the pin, as you will need it later. You will use the screwdriver to push slightly down the mechanical grip, and in the meanwhile you push the pin out of the housing. To extract it, you need to use a small flat screwdriver, about 2mm wide. The force required to push the pin down is significantly less than the force to push the pin out of the housing. So, i will start from the easiest connectors.Įxtracting the pins from floppy disc type Molex connectors and fan connectors

All you need is to know the mechanical grips where and how to reach them.

There are special pin extractors for the molex headers that you can get for as low as $8.00 each (+PP), but unless you are a professional and you extract tens or hundreds of pins daily, i really discourage you to buy them. This is the 'hardest' part compared to the whole procedure, but actually, nothing will be hard after all.

This is how i do it.įirst things first - Extract the pins out of the housing So, i had to find an easy and repeatable way to reuse and/or extend the Molex connectors.

For my current PC configuration, i had for example to extend the 24 pin power supply. Some other times, i needed to extend a PC connector, especially in PC case modding applications. In many occasions, i had the need to draw power from the PC power supply, either because i made a system built-in a computer case, or because i used a PC power supply to provide power to another device. You try to avoid theoretical maximums for production.Author: Giorgos Lazaridis Reuse and-or extend the Molex connectors Typically, power supplies supplied half that for peripherals (5A for both comes to mind). With the 14 AWG cable, you could get 11A on 12V circuit (Pins 1 and 2), 132W, and 11A on 5V circuit (Pins 3 and 4), 55W. And OP 44A/connector.įrom SuperUser (but no reference to external source) Is this a floppy disk connector to the power supply?: Increase wire size to 14 AWG and you do get 11A/pin. Odds are that no actual circuit will have 18A sourced due to other factors. There are other factors: Ambient Temperature. All applications should be tested by the end user.Īs in designer is responsibe. are intended to be a guide in the selection of a connector family. That is 18A supplied and 18A sunk (Ground). 36A per connector theoretical maximum, if 105☌ and 30☌ are maintained. With every circuit energized, for a 4 in-line connector, with 18 AWG wire is 9A/pin. Derating connector due to adjacent conductors. Table shows number of circuits vs size of wire. The maximum current that can be carried is a function of the maximum temperature of the housing (105☌) and the maximum temperature of individual connection (30☌) (and maximum temperature of wire insulation) (and length of wire) (and ambient temperature). The problem is a little bit more complicated than that. So 4 pins at 11A/pin leads to the 44A of OP.
