[0048] Embodiment 1

[0049] Please refer to Figure 1 and Figure 2 The present embodiment provides a connector 1, which comprises a protective shell 11, an adapter 12, a circuit board 13, a charging chip 14 and a connector body 15.

[0050] The circuit board 13 is arranged between the adapter 12 and the connector body 15, and the adapter 12 and the connector body 15 are electrically connected with the circuit board 13, that is, the adapter 12 and the connector body 15 are electrically connected through the circuit board 13.

[0051] The adapter 12 has a first interface 121 for electrically connecting with an external line, and the connector body 15 includes a second interface 151 for electrically connecting with an electronic device. The charging chip 14 is arranged on the circuit board 13. The adapter 12, the circuit board 13, the charging chip 14 and the connector body 15 are encapsulated by the protective shell 11, and the first interface 121 and the second interface 151 extend out of the protective shell 11.

[0052] The inventor of the present application has found that in the design of a conventional charging data line, the charging chip 14 is designed at the line end, which causes the connector 1 of the data line to become a power bottleneck during charging. Even if the charging protocol and the charging wire can provide higher charging power, the actual charging power cannot reach the design power of the charging protocol and the charging wire due to the limitation of the connector 1.

[0053] In the technical solution of the present embodiment, the inventor arranges the charging chip 14 on the circuit board 13 of the connector 1, so that the connector 1 can also be adapted to the corresponding charging protocol, and the power of the connector 1 during charging can also reach the set power of the charging protocol. On this basis, as long as the wire at the line end can meet the corresponding power requirement, the charging can be performed according to the design power of the corresponding charging protocol.

[0054] During use, the first interface 121 of the connector 1 is connected with the interface at the line end, and the second interface 151 of the connector body 15 is connected with the charging interface of the electronic device, so that the electronic device can be charged.

[0055] Please refer to Figure 2 and Figure 3 The protective shell 11 includes a first shell 111 and a second shell 112. The first shell 111 is provided with a first opening 1111 for the first interface 121 to pass through, and the first opening 1111 is adapted to the first interface 121. The second shell 112 is provided with a second opening 1121 for the second interface 151 to pass through, and the second opening 1121 is adapted to the second interface 151.

[0056] The first shell 111 and the second shell 112 are connected, so that the adapter 12, the circuit board 13 and the connector body 15 are encapsulated in the protective shell 11. The first interface 121 of the adapter 12 extends out of the first opening 1111 of the first shell 111, and the second interface 151 of the connector body 15 extends out of the second opening 1121 of the second shell 112.

[0057] The positioning ring 113 is sleeved on the first interface 121 of the adapter 12, and is located inside the protective shell 11 after the connector 1 is completely packaged. The side wall of the positioning ring 113 away from the first interface 121 and the side wall of the positioning ring 113 away from the circuit board 13 are both in contact with the inner wall of the first shell 111. In this way, the positioning ring 113 can well stabilize the first interface 121, greatly improving the stability and reliability of the first interface 121, and avoiding loosening of the first interface 121.

[0058] In the embodiment, the positioning ring 113 is made of a magnetic material, so that the connector 1 is magnetically connected to external lines by the first interface 121. It can be understood that in other embodiments of the application, at least one of the first shell 111 and the positioning ring 113 can be made of a magnetic material.

[0059] Further, please refer to Figure 2 , Figure 3 and Figure 4 , the adapter 12 specifically includes the first interface 121, the first pin 122 and the positioning plate 123.

[0060] The first pin 122 is fitted in the first interface 121, and the pin of the first pin 122 is electrically connected to the circuit board 13. In the embodiment, the number of the first pin 122 is four, and the four first pins 122 correspond to V+, V-, D+ and D- respectively.

[0061] Specifically, the inside of the first interface 121 is provided with a first pin slot 1211 for accommodating the first pin 122. Along the width direction a (as shown in Figure 4 , the first interface 121 defines two opposite edges. Along the thickness direction b (as shown in Figure 4 , the first interface 121 defines two opposite sides. The first pin slot 1211 is arranged on the same side of the inside of the first interface 121, and the four first pin slots 1211 are arranged close to one edge of the first interface 121.

[0062] It should be noted that the above-mentioned "arranged close to one edge of the first interface 121" is intended to express that the four first pin slots 1211 are closer to one edge of the first interface 121, and the distance between the four first pin slots 1211 and the other edge of the first interface 121 is farther.

[0063] Through the above design, the number of the first pin 122 corresponding to the first interface 121 is only four, which can reserve installation space for the charging chip 14. In addition, the four first pins 122 are located on the same side of the first interface 121, which can realize the double-sided conduction function of the first interface 121. The four first pins 122 are arranged close to the edge of the first interface 121, which can make the four first pins more concentrated and reduce the interference on the installation of the charging chip 14, thereby reserving more space for the installation of the charging chip 14.

[0064] In addition, the positioning plate 123 is annular, the fixing plate is sleeved outside the first interface 121 and is fixedly connected to one end of the first interface 121 close to the circuit board 13. The adapter 12 is attached to the circuit board 13 through the positioning plate 123. Specifically, the side of the positioning plate 123 close to the circuit board 13 is provided with a first positioning column 124, and correspondingly, the circuit board 13 is provided with a first matching hole 131 adapted to the first positioning column 124. When the positioning plate 123 is matched with the circuit board 13, the first positioning column 124 is matched in the first matching hole 131. This greatly improves the matching stability of the adapter 12 and the circuit board 13, and prevents the adapter 12 and the circuit board 13 from being offset.

[0065] On the other hand, the positioning plate 123 and the first interface 121 close to the circuit board 13 are provided with a give-way slot 125 for matching with the charging chip 14, and when the adapter 12 is attached to the circuit board 13 through the positioning plate 123, the charging chip 14 is accommodated in the give-way slot 125. Through this design, not only the matching tightness of the adapter 12 and the circuit board 13 is further improved, but also the adapter 12 can also play a protective role for the charging chip 14.

[0066] It can be understood that in other embodiments of the present application, the number of the first pin 122 can be different, and is not limited to four, which can be more than four or less than four. In addition, the arrangement mode of the first pin 122 in the first interface 121 can also be different, which is not limited to this.

[0067] Please combine Figure 2 , Figure 4 and Figure 5 , the outside of the first interface 121 is also provided with a second needle slot 1212, the second needle slot 1212 is recessed from the outer wall of the first interface 121, and the second needle slot 1212 penetrates the positioning plate 123. The circuit board 13 is provided with a cc signal (i.e. link confirmation signal) module (not shown in the figure), and the cc signal module pin 132 is matched in the second needle slot 1212.

[0068] The positioning ring 113 is sleeved outside the first interface 121 of the adapter 12, and the positioning ring 113 is attached to the positioning plate 123. The positioning ring 113 can cover the second pin slot 1212. As shown in Figure 6 , the cc signal module pin 132 is connected to the positioning ring 113. The connector 1 can realize cc signal transmission by using the magnetic properties of the positioning ring 113.

[0069] Please continue to refer to Figure 2 , Figure 3 and Figure 4 . The first matching module 133 is arranged on the side of the circuit board 13 close to the adapter 12, and the second matching module 134 is arranged on the side of the circuit board 13 close to the connector body 15. The first matching module 133 is used to cooperate with the first pin 122 of the adapter 12 to realize electrical connection, and the second matching module 134 is used to cooperate with the connector body 15 to realize electrical connection. The cc signal module pin 132 and the charging chip 14 are arranged on the side of the circuit board 13 close to the adapter 12.

[0070] Please continue to refer to Figure 2 , Figure 3 and Figure 4 . The connector body 15 specifically includes a second interface 151, a second pin 152, and a second positioning column 153. The second pin 152 cooperates with the second interface 151, and the second interface 151 is electrically connected with the second matching module 134 of the circuit board 13 through the second pin 152. The second positioning column 153 is arranged at one end of the second interface 151 close to the circuit board 13. Correspondingly, the circuit board 13 is provided with a second matching hole 135 matched with the second positioning column 153. When the connector body 15 cooperates with the circuit board 13, the second pin 152 cooperates with the second matching module 134 of the circuit board 13, and the second positioning column 153 is accommodated in the second matching hole 135. In this way, the cooperation stability of the connector body 15 and the circuit board 13 can be effectively improved, the deviation between the connector body 15 and the circuit board 13 can be avoided, and the accurate cooperation of the second pin 152 and the second matching module 134 of the circuit board 13 can be ensured.

[0071] In the embodiment, the second interface 151 is an apple interface. It can be understood that in other embodiments of the application, the second interface 151 can also be an Android interface (as shown in Figure 7 ) or a type-c interface (as shown in Figure 8 ). In addition, the second interface 151 can also be multiple, and the second interface 151 is at least two of the Android interface, the apple interface and the type-c interface.

[0072] It should be noted that in other embodiments of the application, the charging chip 14 can also be replaced by other types of smart chips, not limited to the charging chip 14 itself.

It can be understood that the wire 31 is electrically connected with the external end 212 of the base 21, and the connector 1 is also electrically connected with the base 21 after being connected with the base 21. Therefore, the wire 31, the base 21 and the connector 1 can form a complete charging and data transmission circuit to realize charging and data transmission for external electronic devices.

[0079] It should be particularly noted that when the data line 3 is applied to a high-power fast-charging data line with an Apple interface, a fast-charging requirement of 100W or even higher power can be realized. Compared with the current 60W fast-charging when compatible with the Apple interface, the power upper limit is greatly improved.
