1. A power adapter comprising:
- a main body of cylindrical shape, a top of the main body defining a recess, and an annular sidewall enclosing the recess;
a rotation-proof component which is received in the annular sidewall of the main body and which defines a rotation-proof portion extending into the recess;
a plug rotatably mounted in the recess, a side of the plug defining at least one rotation-proof recess; and
,a main shell having a platform formed at an inner side thereof for supporting the main body thereon, the rotation-proof component further having two fixing portions extending oppositely from two ends of the rotation-proof portion and extending out of a bottom of the annular sidewall and bending towards the platform for being sandwiched between the bottom of the annular sidewall and the platform;
wherein the rotation-proof portion is elastically pressed against the plug as the plug rotates in the recess, and is then released into the rotation-proof recess for restraining the plug from reverse rotation.

Abstract
A power adapter has a main body of cylindrical shape. A top of the main body defines a recess and an annular sidewall enclosing the recess. A rotation-proof component received in the annular sidewall of the main body defines a rotation-proof portion extending into the recess. A plug is rotatably mounted in the recess, and a side of the plug defines at least one rotation-proof recess. The plug is rotatably secured in the recess then the rotation-proof portion is elastically pressed against the plug and finally the rotation-proof portion is released into the rotation-proof recess for restraining the plug from reverse rotation.

2. A power adapter comprising:
-
a main body of cylindrical shape, a top of the main body defining a recess, and an annular sidewall enclosing the recess; a rotation-proof component which is received in the annular sidewall of the main body and which defines a rotation-proof portion extending into the recess; and a plug rotatably mounted in the recess, a side of the plug defining at least one rotation-proof recess; wherein the rotation-proof portion is elastically pressed against the plug as the plug rotates in the recess, and is then released into the rotation-proof recess for restraining the plug from reverse rotation; wherein the side of the plug defines a leading recess extending along a circumferential direction with the width thereof decreased gradually, a narrow end of the leading recess is adjacent to the rotation-proof recess, and the rotation-proof portion slides away from the leading recess to the rotation-proof recess. - View Dependent Claims (3)
