[0027] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0028] like Figure 1-Figure 5 As shown, a magnetic circular PD fast charging kit includes a magnetic male connector 1 and a magnetic female connector 2 that are magnetically connected and detachable. The magnetic male connector 1 includes a Type-C male connector 11, a large circular PCB board 12, a rubber sleeve 13, a male magnet 14, and a small circular PCB board 15. The Type-C male connector 11 and the small circular PCB board 15 are both soldered to the large circular PCB board 12, and the Type-C male connector 11 and the small circular PCB board 15 are respectively located on either side of the large circular PCB board 12. The small circular PCB board 15 is provided with a middle solder pad 151 and a circular solder pad 152, which surrounds the middle solder pad 151. The male magnet 14 is annular, and the small circular PCB board 15 is located in the male magnet 14 and protrudes from the male magnet 14. The large circular PCB board 12 and the small circular PCB board 15 are located in the rubber sleeve 13, which is provided with an opening for connecting the Type-C male connector 11 to the circuit board assembly.

[0029] like Figure 1 、 Figure 3 、 Figure 6-Figure 8 As shown, the magnetic female socket 2 includes a female magnet 21, a 3P contact 22 and a female PCB board 23. The female PCB board 23 is a circular PCB board. The 3P contact 22 and the female PCB board 23 are soldered together, and the 3P contact 22 and the female PCB board 23 are electrically connected. The female magnet 21 is annular, and the 3P contact 22 is located in the female magnet 21. The outer diameter of the female magnet 21 and the male magnet 14 are the same. The 3P contact 22 has three PIN pins, namely the CC detection PIN pin 221 located in the middle and the two VBUS power positive PIN pins 222 located on both sides. When the magnetic male connector 1 and the magnetic female socket 2 are magnetically connected through the male magnet 14 and the female magnet 21, the circuit board assembly presses the three PIN pins of the 3P contact 22, and the CC detection PIN pin 221 is connected to the middle solder pad 151, and the two VBUS power positive PIN pins 222 are connected to the annular solder pad 152. Three pads are provided on the back of the mother PCB board 23, namely the VBUS pad 231, the GND pad 232 and the CC pad 233.

[0030] The manufacturing method and working principle of the present invention are as follows: When manufacturing the magnetic male connector 1, the Type-C male connector 11, the large circular PCB board 12, the male connector magnet 14 and the small circular PCB board 15 are put into a customized special fixture after the tinning patch process, and then reflow soldering is performed after fixing. After the four components are welded together, they are plastic-molded and encapsulated to fix the shape, that is, the shape of the encapsulation sleeve 13. The definition of the male connector in the requirements of the PD protocol is that the functions of VBUS (positive power supply), GND (negative ground) and CC (detection pin) need to be brought out for use, wherein the definition of the small circular PCB board 15 is to connect VBUS (positive power supply) and CC (detection pin) by welding with the large circular PCB board 12, and the middle pad 151 of the small circular PCB board 15 is designed as the CC detection pin, and the circular pad 152 is designed as VBUS. The GND connection is defined as the connection between the male magnet 14 and the large circular PCB board 12 after welding. The male magnet 14 is welded to the large circular PCB board 12, firstly to connect the connection, and secondly to prevent the magnet from breaking. When making the magnetic female socket 2, the female socket magnet 21, 3P contact 22, and female socket PCB board 23 are put through the tinning patch process, and then the three components are placed in a customized special fixture, fixed, and then reflow soldered. The 3P contact 22 has three PIN pins, namely the CC detection PIN pin 221 located in the middle and the two VBUS power positive PIN pins 222 located on both sides. The welding between the female socket magnet 21 and the female socket PCB board 23 is defined as the GND power negative pole. To match this, three pads are set on the back of the female socket PCB board 23, namely the VBUS pad 231, the GND pad 232, and the CC pad 233.

[0031] When the utility model is used, the prepared magnetic male connector 1 is inserted into the device to be used, and the magnetic female connector 2 is prepared as a data cable or base kit. The two products are attracted to each other to perform fast charging according to the PD protocol.

[0032] In summary, the main components of the present invention are the magnetic male connector 1 and the magnetic female connector 2. The terminal structure of the two is simple, and the magnetic male connector 1 and the magnetic female connector 2 can be magnetically detached and connected, making it very convenient to use. In addition, the present invention can use the PD protocol function by defining the VBUS, GND, and CC of the magnetic male connector 1 and the magnetic female connector 2. The wire bonding wire is reduced from the original four-core wire to the current three-core wire, reducing material usage and lowering production costs.

[0033] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
