Assembling the power cable

Photos can be enlarged by clicking them. They will open in a new window.
The kit contains the following parts:
  • Plug, 4 pins male;
  • Socket, chassis, 4 pins female;
  • Socket, chassis, 3 pins male;
  • Plug, 3 pins female;
  • Cable 1,20 m, smooth textile covered, 5 strains of litze wire 0,35 mm;
  • 10 ferrules, 1 mm2 (not on the photo)
    •
   
We start with mounting the 3 pin plug on the side of the cable that has the thinner tubing and the cut off copper ends.

Slide the cap over the cable, cut the wires to length.

The yellow wire has the proper length, cut the others to the same length.
   
Strip the cables one at a time and ....

 
   
.... put a 1.0 mm2 ferrule over the end and crimp it.

If you don't have ferrules, you can twist a length of thin solid wire around the litze and solder this.

Litze wire is difficult to solder without ferrule or a wire winding around it.

You need a pair of crimping pliers to crimp the ferrules, but a pair of combination pliers can do the trick as well.
   
Four wires later, you will end up with this.

Of course you can decide to put a ferrule on the yellow wire as well, but it is difficult to get the copper end off, and the yellow cable is too short already to cut the copper end off and fit a ferrule.
   
Next, we can solder the wires to the female plug.

There are 5 wires for 3 pins, so we can combine wires or cut 2 off.

I used brown for HT, white and green for Ground, yellow and grey for filament.

The pins are all numbered, the schematic follows these numbers.

Finally we can slide the cap over the socket, stick in the special nail and mount the strain relief. This one is ready.
   
To mount the square plug without altering the plastic tubing, the hole in the cap has to be made a little wider. I used a reamer, but a drill bit will also do it.

Next, slide the cap on the cable!!

Cut the wires to the desired length.

Strip the wires one at a time and put the ferrules on.
   
Next, we can solder the wires to the male plug.

The pins are all numbered, the schematic follows these numbers.

Finally we can slide the cap over the socket, stick in the special nail and mount the strain relief. This cable is ready.

 
   
And this is what you end up with.
