The side walls comprise a first side wall with a rotatablely movable block, the latching member is defined at the top of the movable block, the latching member moves outward with the movable block rotating.

First claim

What is claimed is:

1. A power adapter comprising:
a cover and a printed circuit board module received in the cover, the cover having a base and an upper cover covering the base, the base having a bottom wall and a plurality of side walls surrounding the bottom wall, the bottom wall and the side walls forming a receiving space for receiving the printed circuit board module, wherein
the cover has a plurality of latching members at the top of the side wall, the latching members are on both ends of the cover, the latching members are defined above the upper cover and extend to each other, the side walls comprise a first side wall with a rotatablely movable block, the latching member is defined at the top of the movable block so as to move outward with the movable block; wherein
the movable block is discrete from but pivotally mounted upon the first side wall, and constantly urged by a spring to a locking position.

2. The power adapter as claimed in claim 1 , wherein the bottom wall has a fixed seat received in the receiving space, the movable block has a positioning pin, one end of the spring is set in the positioning pin, the other end of the spring is fixed to the fixed seat, the spring is defined between the fixed seat and the movable block, the spring is compressed inward with the movable block rotating outward under an external force, the movable block resets with a resetting force of the spring when the external force is releasing.

3. The power adapter as claimed in claim 2 , wherein the spring is in a pre compressive state, the movable block is pushed outward continually, the movable block has a relying portion for relying on one edge of the upper cover, the relying portion is used for keeping the movable block still with no external force.

4. The power adapter as claimed in claim 1 , wherein the bottom wall also has a retaining wall for avoiding the movable block rotating inward excessively.

5. The power adapter as claimed in claim 1 , wherein the first side wall has two fixed walls integrated with the base, each of the fixed walls has a pivotal hole, the movable block has two pivotal rods at two sides, the pivotal rods are received in the pivotal holes respectively.

6. The power adapter as claimed in claim 5 , wherein the pivotal hole extends through to the receiving space, the movable block is set between two fixed walls through the receiving space.

7. The power adapter as claimed in claim 5 , wherein the movable block comprises a body and an operating portion protruding outward from the bottom of the body, the operating portion is set in a lateral surface of the body and for operating by a hand of a user.

8. The power adapter as claimed in claim 1 , wherein the printed circuit board module comprises a printed circuit board, a Micro USB socket and a power connector, the Micro USB socket is mounted onto a lower surface of the printed circuit board and has an interface exposing outward, the power connector is mounted onto an upper surface of the printed circuit board and has a plurality of pin-shaped terminals, the pin-shaped terminals go through the upper cover and expose outside.

9. The power adapter as claimed in claim 8 , wherein the printed circuit board has a switch module, the power connector, the Micro USB socket and the switch are defined in three different edges respectively.

10. The power adapter as claimed in claim 1 , wherein the bottom wall has a plurality of ribs, the ribs form a supporting surface for supporting the printed circuit board module, the side wall has a pair of stopping blocks, the stopping blocks are relying on the edge of the printed circuit board module for avoiding the printed circuit board module shaking.

11. A power adapter comprising:
a cover defining a base and an upper cover covering the base, and the base having a bottom wall and a peripheral wall around the bottom wall, the peripheral wall and the bottom wall cooperatively define a receiving space; and
a printed circuit board module retained within the receiving space;
wherein at least two latching members respectively disposed on two opposite ends of the assembled peripheral wall and the upper cover in a lengthwise direction, said two latching members are located above an upward face of the upper cover and extend toward each other, and the peripheral wall is equipped with a movable block, and one of the latching members is formed on a top of the movable block and can move outwardly with the movable block; wherein
said movable block is discrete from but pivotally mounted upon the peripheral wall and constantly urged by a spring to a locking position.

12. The power adapter as claimed in claim 11 , wherein the bottom wall provides a fixed cavity located in the receiving space, and said spring is set between the fixed cavity and the movable block by one end fitting for a positioning post projecting from a lower portion of the movable block and the other end retained to the fixed cavity, the spring is compressed inward while the movable block rotates outwardly under an external force.

13. The power adapter as claimed in claim 11 , wherein said movable block is pivotal about the peripheral wall along a pivot axis extending along a horizontal transverse direction perpendicular to said lengthwise direction, and is equipped with a spring constantly urging a bottom portion of the movable block to move outwardly along said lengthwise direction so as to have the corresponding latching member located in an inward locking position when no outward external force is imposed upon said latching member.

14. The power adapter as claimed in claim 13 , wherein said peripheral wall forms a pivotal hole inwardly communicating with the receiving space in the lengthwise direction so as to allow the movable block to be assembled thereinto along the lengthwise direction, and the upper cover abuts against an upper portion of the movable block to resist a force derived from the spring and to stop the latching member in a locking position.

15. The power adapter as claimed in claim 11 , wherein the other of said two latching members is immovable.

16. The power adapter as claimed in claim 11 , wherein the printed circuit board module includes a printed circuit board with an I/O (Input/Output) connector and a power connector located upon two opposite surfaces of the printed circuit board.

17. The power adapter as claimed in claim 16 , wherein the I/O connector has a metallic shell with a pair of outward tabs to be received within a pair of slots formed in the printed circuit board.

18. A power adapter comprising:
a cover defining a base and an upper cover covering the base, and the base having a bottom wall and a peripheral wall around the bottom wall, the peripheral wall and the bottom wall cooperatively define a receiving space; the peripheral wall providing at least two latching members respectively disposed on two opposite top ends thereof, which are located above the upper cover and extend toward each other of which one is outwardly moveable; and
a printed circuit board module retained within the receiving space and including a printed circuit board with a power connector and an I/O (Input/Output) connector respectively mounted upon two opposite surfaces of the printed circuit board; wherein
upper ends of terminals of the power connector extend upwardly beyond the upper cover, and the I/O connector includes a metallic shell with a pair of outward tabs received within a pair of slots formed in the printed circuit board so as to have the metallic shell intimately abut against the printed circuit board.
