Power adapter

Abstract

A power adapter includes a body, a plug, and an operation board. The plug is detachably received in and electrically connected to the body. The plug has an engagement slot. The operation board is rotatably received in the body and includes a hook, a pressing portion and a pop portion. The hook latches to the engagement slot to secure the plug to the body. The pressing portion is pressed by external forces. The pop portion is positioned below the plug. When the pressing portion receives an external force, the pressing portion rotates towards the body and drives the pop portion to rotate away from the body, whereby the pop portion pops up the plug from the body.

FIG. 1 illustrates an exemplary embodiment of a power adapter 100, which is configured to be coupled to a power socket to charge for an electronic device. The power adapter 100 includes a body 10, a plug 20, and an operation board 30.

Referring to FIG. 2, the body 10 includes a first groove 11, a guiding slot 12, a second groove 13, a pair of conductive columns 14 and a fixing board 15. The body 10 further includes a top surface 102 and a side surface 104 adjacent to the top surface 102. A portion of the top surface 102 recesses to form the first groove 11. In at least one embodiment, the first groove 11 is substantially square and includes a bottom wall 112. A first receiving groove 114 and a second receiving groove 116 are formed by recessing from the bottom wall 112. The first receiving groove 114 is adjacent to the second receiving groove 116. The conductive columns 14 are received in the first receiving groove 114 in parallel and configured to electrically connect the plug 20 and a circuit board (not shown) of the body 10.

The guiding slot 12 is formed by recessing a portion from the side surface 104. The guiding slot 12 is communicated with the first groove 11. An end surface of the guiding slot 12 away from the first groove 11 defines a hole 122. The second groove 13 is formed by recessing a portion from the top surface 102 and communicated with the first groove 11. In at least one embodiment, the second groove 13 is substantially rectangular. The second groove 13 has a smaller width and a greater depth than that of the first groove 11. A lower portion of the second groove 13 extends to a below of the first groove 11 and adjacent to the second groove 116. The fixing board 15 is mounted on a bottom of the second groove 13 and extends to a below of the bottom wall 112, while a portion of the fixing board 15 is exposed by the second groove 116. The fixing board 15 is configured to secure the operation board 30.

Referring to FIGS. 2 and 3, the plug 20 includes a main portion 22, a conductive portion 24, pins 26, an engagement slot 28, and a protrusion 29. The main portion 22 is substantially L-shaped and detachably received in the first groove 11 and the guiding slot 12. The conductive portion 24 is substantially column shaped and formed by protruding from an internal surface of the main portion 22. The conductive portion 24 is received in the first receiving groove 114 and electrically connected to the conductive columns 14. The conductive portion 24 defines conductive holes (not shown) for receiving the conductive columns 14. In at least one embodiment, the plug 20 includes two conductive portions 24 for receiving the conductive columns 14. The pins 26 are formed by protruding from an end of the main portion 26 away from the conductive portion 24. The pins 26 are configured to be coupled to the socket for conducting electricity. In at least one embodiment, the conductive columns 14 extend along a Z-axis direction and the pins 26 extend along a Y-axis direction. The engagement slot 28 is defined on an end of the main portion 22 and adjacent to the conductive portion 24. The engagement slot 28 is configured to secured the operation board 30. The protrusion 29 is formed by protruding from an end of the main portion 22 away from the engagement slot 28 and configured to be coupled to the hole 122 for securing an end of the main portion 22 to the body 10.

A quantity of the pins 26 and a structure of the pins 26 can be multiple, which can be adapted to different standard sockets in different places. In at least one embodiments, the quantity of the pins 26 can be two and the structure can be substantially rectangular sheet.

Referring to FIGS. 2, 3, and 4, the operation board 30 is substantially ladder-shaped and includes a shaft 31, an elastic piece 32, a pop portion 33, a connecting portion 34 and a pressing portion 35. The shaft 31 is mounted between the fixing board 15 and the bottom wall 112. The pop portion 33 and the pressing portion 35 are perpendicularly connected to opposite ends of the connecting portion 34 and extend in opposite directions. The end of the connecting portion 34 connecting the pop portion 33 is secured to the shaft 31, while the other end connecting the pressing portion 35 forms a hook 36. The hook 36 is configured to latch to the engagement slot 28 to limit a movement of the plug 20 in a Z-axis direction, thereby preventing the plug 20 falling off from the body 10. The elastic piece 32 hitches the shaft 31 and is elastically resisted to the connecting portion 34 and the fixing board 15. Thus, the operation board 30 can rotate corresponding to the body 10 based on the shaft 31, and the elastic piece 32 provides an elastic restoring force. The pop portion 33 is received in the second receiving groove 116 and adjacent to the first receiving groove 114. The pop portion 33 is coplanar with the bottom wall 112 is configured to pop up the plug 20. The pressing portion 35 is configured to be pressed by the user. In at least one embodiment, the operation board 30 can be formed by plastic injection molding.

In manufactory, the operation board 30 is received in the second groove 13, the pop portion 33 is received in the second receiving groove 116. The pop portion 33 and the shaft 31 are mounted the fixing board 15, the elastic piece 32 hitches the shaft 31 and is elastically resisted to the connecting portion 34 and the fixing board 15. The pressing portion 35 is coplanar with the top surface 102 of the body and capable of rotating in the second groove 13 circumfusing the shaft 31. The plug 20 slides along the guiding slot 12 to be received in the first groove 11 and the guiding slot 12. The protrusion 29 is engaged to the hole 122 to secured an end of the plug 20 to the body 10. The conductive portion 24 is received in the first receiving groove 114 and electrically connected to the conductive columns 14. The pins 26 extend outwardly for being connected to the socket. The engagement of the conductive portion 24 and the first receiving groove 114 and the engagement of the protrusion 29 and the hole 122 can limit a movement of the plug 20 in the X-axis and the Y-axis directions. The end of the main portion 22 having the engagement slot 28 is overlapped above the pop portion 33, the hook 34 latched to the engagement slot 28 to secure the plug 20 on the body 10.

Referring to FIG. 5, when the user need to change the plug 20 to adapt to different standard sockets, may press the pressing portion 35 to force the pressing portion 35 to rotate towards the fixing board 15. The pop portion 33 rotates away from the fixing board 15 to push the main portion 22, thus the hook 36 detaches from the engagement slot 28, therefore, the pop portion 33 pops up the plug 20. Then another plug 20 with different standard pins 26 can be changed to the body 10.

The power adapter 100 can easily secure and pop up the plug 20 via the operation board 30, thus, the power adapter 100 can conveniently change different standard plugs 20 to be adapted to different standard sockets, which has a great universality and practicability.

It is believed that the embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the scope of the disclosure or sacrificing all of its advantages, the examples hereinbefore described merely being illustrative embodiments of the disclosure.
