Try Allied Electronics on-line. Lots of connectors.

I don't know where you got them... but I am looking for something for the
same use.
 
What I WANT is a 40 amp rated automotive blade fuse holder (1/4 inch blades)
that I can mount on the plane (I have found the 40 amp fuses in that size)
Since my plane draws under 30 amps doing static thrust tests, but all
components are rated 60 amps or more, a 40 amp fuse should be a good size
for me.
 
There is a larger form blade type fuse that I know has higher rated fuses.
 
Combining the safeties of a quick disconnect and a fuse in one just seems
like a good idea to me.  Currently I have one of my 4 mm bullet connections
accessable for my quick disconnect, but its not as easilly accessed as I
would really like.

All, we are using these connectors to make up our Jumper Plugs for higher
amp, and Pattern electrics. The female goes in the plane on the Plus lead
from the battery to the ESC and is mounted with a bracket to take the "push
in--pull out loads.The Male pins are jumpered with #12 wire and then
insulated with heat shrink,  as a result the resistance through the jumper
is not measurable on my Fluke
We call it "Sparky" because it snaps when you plug it in--ESC load-.This way
you turn on the Rx. and check the plane out--then plug the jumper in--listen
to the arming/check sounds- move the throttle to idle--and go fly. When you
land you pull the plug--then turn the Rx. off--that way you do not rely on
the ESC or throttle "off" to make sure the motor does not turn back on.
Have seen a couple actually do that after landing and stopping, once before
someone got to the plane, and the second as it was being carried back.  
The plastic body measures 0.355in long X 0.280in thick X 0.500in wide.
Contact area is about 0.160in deep and 0.350 wide-gold plated-, on each
side, so it can easily handle the I.
Now the problem--I bought these in a hobby shop several years ago, and of
course he no longer has them, or even remembers them. They have more contact
area than other similar   connectors (Anderson power poles),so are the best
thing out there I have found. 
Does anyone know where I can get some, or who may have made them. I assume
they were originally made for cars.
There is another e-mail with another view
Thanks
Jerry
