A Plug for the QC Port:
1. Short term, get something to safely hold and align
the pins (2 big for power, 7 small for handshake) to
allow us to begin experiments involving the vehicle.
2. Long term, provide a method by which interested
folks can obtain a very inexpensive cable-end connector,
for their own experimental usage. No, not UL listed.
First, reasonably accurate dimensions were needed,
and I think that we are doing well in that respect, at least
sufficiently well to make something that fits the LEAF's
QC port socket.
A 3D model was attempted on SketchUp, but it appears that
the free version is primarily suited for modeling shells,
or entirely solid objects. Maybe there is a way to model
internal voids within the solid, but I am not an expert in
using SketchUp, so I might be missing something.
However, a derived STL file could be used to drive
a 3D printer, I believe, with the appropriate settings
in the "slicer" for external walls and internal filler.
Another 3D model was made using Binder (?) and used to
print a 4-section 3D-Printed "plug" which will be sufficient
to hold the pins for our first experiments. No, it does not
yet have the latch and interlock, but that is being worked on.
Printed in PLA plastic, in a nearby country.
The handle is in two halves, connecting to a pin-retainer plate,
which attaches to the rear of the plug (pin holder part) that
mates with the QC socket.
