The holes in the prongs
Have you ever taken a close look at the male prongs on
your power cable? Even the best power cords in the
world have them. Ever wonder why they are there?
Our research has indicated that these holes, which
reduce the contact surface area of the male prong, were
first introduced over a quarter of a century ago to solve
the problem of plug grip when inserted into the female AC
socket.
Years ago, and well before the advent of the Hospital
Grade receptacle (like the PS Power Port), plug grip
strength was achieved by the addition of small dimples in
the female AC outlet. These dimples, which are no
longer manufactured, snapped into the associated holes
on the male prongs to achieve a tighter connection.
So, while the dimples have disappeared the holes have
not. We're certain there are probably half a dozen
reasons why these are still there, but this explanation was
the best we could find. |

，其實是緊急時，可以及時輕易扯下插頭。而且接觸面大，電阻小比較不會產生高熱。
呵呵呵~~~~~長知識!!!
