one rim is shown of an yo yo shaped adapter housing 25 of the power adapter 10 fig1 shows an outer surface 27 of the adapter housing 25 preferably the yo yo shaped adapter housing 25 is made of hardened and light weight plastics or acrylics further the central portion of the outer surface 27 is preferred to be manufactured in a manner unable to be seen through however the rim 22 that is integral to the outer surface 27 is preferred to be made either clear or translucent the apple computer logo 30 is shown to demonstrate the possibility of the placement of a product logo on the outer surface 27 it 30 is shown for illustrative purposes only and not as a part of the present invention fig2 is a simplified and side view of the yo yo shaped adapter housing 25 showing how the dc power cable 20 is wound and placed around a spool 35 inside an annular groove 37 of the adapter housing 25 the dc connector 15 is drawn in a simplified manner to better illustrate how its flange 17 snaps into the annular groove 37 between the two rims 22 and 23 the flange 17 is made of plastics with a certain amount of resilience for the ease of engaging with the rims 22 23 fig2 is further simplified in that it shows neither the ac to dc regulation electronics nor the mechanical configuration inside the spool 35 as mentioned earlier the electronics for the present invention is well known in the art however fig2.
