Adapter J2J SOW:
1. Unzip 95-j1772-xx_sldwks.zio and 95-j1772-xx.rar from folder J2J Adapter/3D/August 25 2023
2. Open project. There are 3 major objects
a. Charger Plug: 55-j1772_charger
b. J2J Adapter,
c. EV Inlet: 55-j1772_recept

3. Work on the J2J Adapter ONLY. It is made of many parts. Three parts are plastic parts:
a. Plug: 50-j1772_plug-xx
b. Inlet: 50-j1772_recpt_mod-xx
c. Latch: 50-j1772_latch_v2

"Party line"
"Ridge"
J2J Adapter PLUG wall: make
it 4.1 mm
Remove this RIDGE and
add a GROVE
J2J Adapter Plug: 50-j1772_plug-xx
4. Work on Plug and Inlet:
a. increase the thickness of external walls (both parts) to 4.1 mm. Do not modify the internal side
and shape of the internal walls (both parts). Note: the overall cross section of the device will
increase, however the internal shape and dimensions must not change.
b. Inner and outer walls draft angles according to the slides 9-11 in doc ELEVATE Mechanical
Update.pdf. This doc reports the discussion results with the injection molding contractor Slopes
of the walls are needed to extract the plastic part from the mold tooling after injection of the
plastic.
c. Outer external tapering surface should be rebuilt as a spline surface.

d. Modify the mating between the two parts in "Tongue and groove joint with energy director".
Note. Tongue is on Plug and Groove on Inlet. Use these data (figures are for illustration only, do
not use data in these figures):

Wall thickness (both parts) is W= 4.1 mm (E + C + F + C + E = 1 + 0.05 + 2 + 0.05 + 1
mm)
Grove depth, G = 10 mm from
Tongue width, F = 1.5 mm
Tongue length (D+G) = 0.7 + 10 = 10.7 mm
Tongue sharp edge angle = 90 degree
Tongue side draft angle = 4 degrees
