[0020] As Figures 1-3 shown, the embodiments of the present utility model include:

[0021] A magnetic adsorption type electrical connector for a wheel hub motor, comprising a female terminal wire end 1 and a male terminal wire end 2. The female terminal wire end 1 is provided with a female terminal positioning member 3. A plurality of Hall jacks 4 and phase current jacks 5 are arranged on the female terminal positioning member 3. A female terminal magnet 6 is embedded in the female terminal positioning member 3. The male terminal wire end 2 is provided with a male terminal positioning member 7. A slot 8 for cooperating with the female terminal positioning member 3 is formed on the male terminal positioning member 7. A plurality of Hall pins 9 for cooperating with the Hall jacks 4 and phase current pins 10 for cooperating with the phase current jacks 5 are arranged in the slot 8. A male terminal magnet 11 is embedded in the male terminal positioning member 7. The female terminal magnet 6 and the male terminal magnet 11 have opposite polarities. The female terminal positioning member 3 is inserted into the male terminal positioning member 7 by the mutual attraction of the female terminal magnet 6 and the male terminal magnet 11.

[0022] Wherein, when the female terminal positioning member 3 and the male terminal positioning member 7 are inserted into each other, the female terminal magnet 6 and the male terminal magnet 11 are aligned in position.

[0023] Further, there are two female terminal magnets 6 and two male terminal magnets 11 respectively. The Hall jacks 4 and the phase current jacks 5 are distributed in the middle of the female terminal positioning member 3. The female terminal magnets 6 are arranged at both ends of the female terminal positioning member 3. The Hall pins 9 and the phase current pins 10 are distributed in the middle of the male terminal positioning member 7. The male terminal magnets 11 are arranged at both ends of the male terminal positioning member 7.

[0024] Further, the Hall jacks 4, the phase current jacks 5, the Hall pins 9, and the phase current pins 10 are all arranged in a single-column straight line at equal intervals. The Hall jacks 4 and the phase current jacks 5 are arranged in parallel. The Hall pins 9 and the phase current pins 10 are arranged in parallel.

[0025] Further, the female terminal wire end 1 is encapsulated with a female injection molded housing 12, the female injection molded housing 12 has a female docking plane 13, and the female positioning member 3 is centrally arranged on the female docking plane 13 in a boss shape; the male terminal wire end 2 is encapsulated with a male injection molded housing 14, the male injection molded housing 14 has a male docking plane 15, and the male positioning member 7 is arranged in a cylindrical shape surrounding the edge of the male docking plane 15; the male docking plane 15 cooperates with the female docking plane 13.

[0026] Further, the corners of the female positioning member 3 and the male positioning member 7 are provided with rounded corners that fit each other, and an annular sealing ring 16 is arranged around the side surface of the female positioning member 3.

[0027] This product is used for the electrical connection of the hub motor of an electric assist two-wheeler. Among them, the male and female connectors fix the male and female ends through the magnetic attraction of magnets. At the same time, the male terminal pins and the female terminal sockets are mutually matched to form the transmission of phase current and Hall signals, facilitating the assembly of the entire process connector. Both the male and female connectors contain two magnets, and the end faces of the two magnets have opposite polarities, one side is the N pole and the other side is the S pole. When mating with the male magnet 11, the opposite polarities attract each other to form a closed state. When the male and female connectors are inserted backwards by 180 degrees, the same polarities repel each other, forming a polarity anti-fooling function, ensuring reliable performance. The female connector is provided with an integral circumferential annular sealing ring 16. When the male and female connectors are mutually matched, the female end sealing ring and the male end inner cavity are pressed against each other to form a sealed waterproof structure, which can reach the waterproof level of IPX7. The motor end outgoing line uses a flat wire connection, saving the space for opening holes and the convenience of wiring.

[0028] In addition, the male and female connectors fix the male and female ends through the magnetic attraction of magnets. At the same time, the male terminal pins and the female terminal sockets are mutually matched to form the transmission of phase current and Hall signals. The male positioning member 7 is in a long strip shape, and 3 phase current pin 10 terminals are arranged side by side on one side, and 6 Hall signal pin terminals are arranged side by side on the other side. The magnets are symmetrically distributed on both sides of the positioning member. At the same time, the end faces of the two magnets have opposite polarities, one side is the S pole and the other side is the N pole. The female positioning member 3 is in a long strip shape, and 3 phase current socket 5 terminals are arranged side by side on one side, and 6 Hall signal socket terminals are arranged side by side on the other side. The magnets are symmetrically distributed on both sides of the positioning member. Corresponding to the male end, the end faces of the two magnets have opposite polarities, one side is the N pole and the other side is the S pole. When mating with the male magnet 11, the opposite polarities attract each other to form a closed state. When the male and female connectors are inserted backwards by 180 degrees, the same polarities repel each other, forming a polarity anti-fooling function. When the male and female connectors are mutually matched, the female end sealing ring and the male end inner cavity are pressed against each other to form a sealed waterproof structure.

[0029] In summary, the present utility model provides a magnetic-attraction type electrical connector for a wheel hub motor. The cavity of the male end positioning member 7 accommodates the pin terminals, enabling the terminals to be protected by a fence, which can effectively reduce the risk of deformation of the pin terminals. The magnetic-attraction mutual matching fixing method can significantly improve the convenience of plugging and unplugging and assembling the connector. At the same time, the elastic sealing ring greatly enhances the waterproof performance of the product and improves the reliability of the product during long-term use.
