Detailed Description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, the same components are denoted by the same reference numerals, and redundant description thereof is omitted. The drawings are schematic and the ratio of the dimensions of the components and the shapes of the components may be different from the actual ones.

With reference to figure 1 of the drawings,

the utility model provides an ultra-thin charger, it can include the shell and range upon range of the PCBA (Printed Circuit Board Assembly) 2 that sets up in the shell in proper order, participate in gland 3, AC shell fragment 4 and AC and participate in 5. The pin gland 3 can be used for capping the AC elastic piece 4 and the AC pin 5, one end of the AC elastic piece 4 can be welded on the PCBA, and the other end of the AC elastic piece 4 can be electrically connected with the AC pin 5.

The utility model discloses in, through reasonable configuration PCBA2 in the shell, participate in gland 3, AC shell fragment 4 and AC and participate in the position of 5, also participate in gland 3, AC shell fragment 4 and AC through with PCBA2, participate in 5 and range upon range of the setting in proper order in the shell, can greatly reduce the utilization ratio of shell inner space from this, can reduce the volume of this charger.

In some examples, the peripheral corners of the housing of the ultra-thin charger may be of a circular arc design.

In this embodiment, the PCBA may include a PCB (Printed Circuit Board), a power storage Circuit, and an AC-DC conversion Circuit, which are assembled on the PCB.

In some examples, the power storage circuit, the AC-DC conversion circuit, and other electronic devices may be assembled on the PCB by SMT (Surface Mounted Technology) top or DIP (dual in-line package) packages on a PCB basis. In this case, the PCBA can be conveniently integrated.

In some examples, the power storage circuit may be a rechargeable battery such as a lithium battery, a lead storage battery, or the like.

In some examples, the AC-DC conversion circuit may be used to convert the AC power introduced by the AC pins into DC power for output to the power storage circuit for storage.

In the present embodiment, the housing may include an upper case 11 and a lower case 12. A tapping process may be performed inside the upper case 11 and the lower case 12. Thereby, the usage volume of the space in the housing can be further saved.

In this embodiment, one side of the PCBA may be provided with a USB interface 21. Therefore, the equipment needing to be charged can be conveniently plugged and charged.

In some examples, the number of USB interfaces may be two.

In this embodiment, the ultra-thin charger may further include a USB cover 6, and the USB cover 6 may be disposed on the side of the USB interface 21 for covering the USB interface; the USB cover 6 may be reserved with a socket for plugging and charging the device requiring charging. Therefore, the USB interface can be conveniently sealed, and charging of devices (such as mobile phones, cameras and other electronic products) needing charging can be conveniently carried out.

In the present embodiment, the inner surface of the lower case 12 may be provided with a groove for receiving the AC pin 5. Therefore, the AC pins can be conveniently fixed and can be conveniently charged by the direct heterodyne plug-in power supply of the ultrathin charger.

In the present embodiment, the lower case 12 is provided with an opening 121 for plugging at a position corresponding to the AC pin 5. Therefore, the ultra-thin charger can be charged conveniently by an external power supply of the AC pin 5.

In this embodiment, in order to maximize the utilization of the internal space of the ultra-thin inflator, first, the wall thickness of the housing can be designed as thin as possible while satisfying the conventional mechanical properties and fire-resistance rating; and aiming at the condition that the height of the local element and the height of the surface of the patch are high, the inner surface of the shell can be designed and processed by adopting glue digging.

Second, the PCBA2 stack assembly also employs an unconventional assembly method, where one end of the PCBA insert may be assembled facing the AC pins 5 and one end of the PCBA patch may be assembled facing the face housing. The assembling mode can be vertical assembling from top to bottom. The assembling mode can maximize the internal space of the charger, and the requirement on the design space ratio of the AC elastic sheet 4 is reduced.

Thirdly, the AC elastic sheet 4 is also optimally adjusted and designed on the basis of the existing elastic sheet, and the AC elastic sheet 4 can be directly welded on the PCBA2 in a smart assembly mode because the product is designed in a vertical assembly mode. Therefore, the internal space of the product can be utilized to the maximum extent.

Finally, the inner surface ribs of the shell can take factors such as product appearance and the like, and the ribs can be connected to the arc-shaped inner wall of the shell. Therefore, the strength of the rib and the rigidity of the product can be guaranteed.

In the utility model, the positions of the PCBA2, the pin gland 3, the AC elastic sheet 4 and the AC pin 5 are reasonably configured in the shell, namely the PCBA2, the pin gland 3, the AC elastic sheet 4 and the AC pin 5 are sequentially stacked in the shell, so that the utilization rate of the space in the shell can be greatly reduced, and the volume of the charger can be reduced; and the AC plug pins 5 can be used for directly externally plugging a power supply to charge the ultrathin charger, so that an additional charging wire is not needed, and the charging mode of the conventional charger can be greatly improved.

While the present invention has been described in detail in connection with the drawings and the examples, it is to be understood that the above description is not intended to limit the present invention in any way. Those skilled in the art can modify and change the present invention as needed without departing from the true spirit and scope of the present invention, and such modifications and changes are intended to fall within the scope of the present invention.
