  • Patent number: 7983064
    Abstract: A power adapter includes an insulation casing. A plug module has at least one plug pin which defines a plug end protruding out of the insulation casing and an inserting end opposite to the plug end received in the insulation casing. The insulation casing receives a printed circuit board, at least one connecting member and conductive member therein. The conductive member is fixed on the printed circuit board and defines a receiving space. The connecting member has a contact portion received in the receiving space of the conductive member for electrical connection therebetween and a retaining portion connecting with the inserting end of the plug module. The assembly structure of the power adapter is simplification.

  • Patent number: 7787238
    Abstract: A power supply adapter includes a casing defining at least one inserting groove therein, at least one resilient piece disposed in the casing and having a locating portion and a resisting portion extended gradually upward from the locating portion, and a plug module rotatablely disposed in the casing. The plug module has at least one retaining block disposed in the inserting groove of the casing and capable of rotating around the resisting portion of the resilient piece. A connecting terminal runs through the retaining block to form an inserting portion and a projecting portion at opposite sides of the retaining block. The projecting portion is capable of compressing the resisting portion when the inserting portion is raised erectly to be exposed externally from the inserting groove.
