Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of electronic equipment, and particularly relates to a fast-charging charger. BACKGROUND

[0002] The charger is a device for converting alternating current into low-voltage direct current. The charger is widely used in various fields, especially in the field of life. The charger is widely used for charging common electrical appliances such as mobile phones and cameras. The charger is a static current conversion device that converts alternating current with fixed voltage and frequency into direct current. It is used everywhere in life and is an indispensable device. However, the common chargers on the market have a series of defects. For example, the charger is prone to heat during charging. The ordinary charger cannot well dissipate heat, and the heat dissipation efficiency is too low. The heat dissipation problem of the fast-charging charger is particularly serious.

[0003] In view of the insufficient heat dissipation of the charger, the following improvements are mainly made. First, the heat dissipation structure is increased. Therefore, the charger needs more space and has a larger volume. Accordingly, the assembly process of the charger becomes more complex, and the enterprise cost is increased. Second, the local components on the circuit board are locally glued and locally cooled. The heat dissipation efficiency is still limited. The reason why the entire glue is not filled is that the existing charger structure cannot be completely sealed. The glue will flow out from the unsealed opening (the USB interface and the foldable plug) before solidification, which makes it impossible to achieve full glue filling in the assembly process.

[0004] Therefore, in order to effectively solve the heat dissipation problem of the charger, the structure of the charger needs to be further improved. SUMMARY

[0005] The purpose of the application is to provide a fast-charging charger to solve the problem of low heat dissipation efficiency of the fast-charging charger in the prior art.

[0006] To achieve the above purpose, the technical scheme adopted by the application is as follows:

[0007] A fast-charging charger, comprising an upper cover plate, a lower cover plate and a shell main body, the upper cover plate is connected with the top of the shell main body, the lower cover plate is connected with the bottom of the shell main body, and a PCB circuit board is arranged in the shell main body, characterized in that the PCB circuit board comprises a circuit board main body part and a circuit board connecting part; a partition is arranged in the shell main body, so that the shell main body is divided into an upper cavity and a lower cavity; a through hole is formed in the partition, and only the circuit board connecting part passes through the through hole; the circuit board main body part is arranged in the lower cavity, and the lower cavity is filled with silica gel; and the circuit board connecting part passes through the through hole of the partition and is connected with an alternating current plug arranged in the upper cavity.

[0008] In this invention, the AC plug includes two metal prongs and a plastic body connecting the two metal prongs.

[0009] Furthermore, the plastic body is cylindrical.

[0010] Preferably, the top surface of the partition is provided with a plug holder with a support hole, and the AC plug is fixed to the support hole of the plug holder by a plastic body, so that the AC plug can rotate on the plug holder.

[0011] In some embodiments of the present invention, the upper cavity of the outer shell body is provided with a conductive spring, one end of which is connected to the circuit board connection part, and the other end is in contact with the metal plug of the AC plug.

[0012] Furthermore, the top surface of the partition is provided with a spring support, and the conductive spring is fixed on the spring support.

[0013] The present invention can be improved by having two slots on the upper cover plate that match the AC plug. With this arrangement, the AC plug can be exposed and retracted through these slots during rotation.

[0014] Furthermore, plastic rivets are provided on the bottom surface of the upper cover plate, and correspondingly, a mounting bracket is provided on the top surface of the partition, the mounting bracket having fixing holes that match the rivets.

[0015] Furthermore, there are two plastic rivets and two mounting brackets.

[0016] The invention can be further improved by providing a USB port on the lower cover plate.

[0017] The present invention has the following beneficial effects:

[0018] (1) The fast charger of the present invention improves the internal structure of the charger by adding a partition layer, so that the main body of the circuit board is located in the lower cavity, thereby filling the entire space of the lower cavity with silicone material and improving the heat dissipation efficiency of the charger.

[0019] (2) The silicone used for potting the fast charger of the present invention has good thermal conductivity and insulation properties. Although silicone is added, the materials such as heat sink, fixing glue, insulating sheet and insulating tape are reduced, and the overall material cost is reduced. Moreover, by adopting this fast charger structure, the packaging process steps of the charger are greatly reduced, which greatly simplifies the production process and makes it more convenient and faster.

[0020] (3) The present invention sets up a partition, on which a plug support, a spring support and a mounting support are set up to fix the AC plug, the conductive spring and the rivet of the top cover plate respectively. After the top cover plate is ultrasonically welded to the outer shell body, each component is fixed and has strong drop resistance. Attached Figure Description

The PCB circuit board 6 includes a circuit board main body 601 and a circuit board connecting part 602. The circuit board main body 601 is located in the lower cavity of the main body 1. The remaining space of the lower cavity is filled with silicone material (not shown in the figure). The silicone material achieves good heat dissipation and also plays a role in fixing the circuit board and its electrical components. The circuit board connecting part 602 is set through the through hole 11 of the partition 7, and the size and thickness of the circuit board connecting part 602 are similar to the size of the through hole 11. In this way, the silicone will not flow out of the through hole 11 during the silicone filling process.
