But even finding the #Fischer / #Phylion charging plug for sale seems to be pretty impossible.
There are a handful of OEM charger manufacturers, but no one sells the plug / cable assembly without a charger.
And it doesn't even have a real designation, it's simply called "#trapezoid 5-pin" everywhere (DE: #Trapezstecker)
Except for the custom metal shield it appears to follow Sub-D dimensions for pin pitch and diameter.

Anybody got an idea how it's called or where to get one by chance?
