[0031] During the use of electronic devices, data cables are usually used for power transmission or data transmission. The connection between the data cable and the electronic device is usually plug-in, but the interfaces of different devices are different, resulting in different data cable styles, which is inconvenient to use. Magnetic connectors are now mostly used for connection. Through magnetic adsorption, it is more convenient to connect or disconnect than plug-in connection. However, the transmission can only be achieved between the connector and the connector seat by aligning their respective conductive parts. It is often necessary to find the corresponding position by rotation, and conduction can be achieved at a specific angle.

[0032] In order to solve the above technical problems, the utility model provides a magnetic charging connector and a charging structure, which realizes the transmission of magnetic field by arranging magnets and magnetic conductive parts, and realizes magnetic connection through the magnetic conductive parts. In addition, the magnetic conductive parts are arranged in a ring shape and spring needles are arranged coaxially with the magnetic conductive parts. The spring needles and the magnetic conductive parts serve as positive and negative poles respectively. The negative pole of the charging end of the electronic device is connected to the spring needle, and the positive pole can be rotated to any angle on the magnetic conductive part to realize conduction charging, thereby improving the convenience of charging.

[0033] In an embodiment of the utility model, the magnetic charging connector includes:

[0034] The first connector 100 includes a magnet 110 and a magnetic conductive member 120. The magnetic conductive member 120 is disposed at one end of the magnet 110 and contacts the magnet 110 to form a magnetic attraction. The magnetic conductive member 120 is annular; and

[0035] A spring needle 200, the spring needle 200 passes through the magnet 110 and the magnetic conductive member 120, and the needle head of the spring needle 200 protrudes from the magnetic conductive member 120;

[0036] The spring pin 200 and the magnetic conductive member 120 are coaxially arranged and serve as the positive and negative poles respectively.

[0037] In the technical solution of the utility model, the magnetic charging connector is used to connect the electronic device to charge the electronic device, wherein the magnetic charging connector is equivalent to a male head, and the electronic device has a female head, such as Figure 1 - Figure 3 As shown, the magnetic charging connector includes a first connector 100 and a spring pin 200. The first connector 100 includes a magnet 110 and a magnetic conductive member 120. The magnetic conductive member 120 is arranged at one end of the magnet 110 and contacts the magnet 110. The magnetic field is transmitted to the magnetic conductive member 120 through the magnet 110, so that the magnetic conductive member 120 has a magnetic attraction effect. The spring pin 200 passes through the magnet 110 and the magnetic conductive member 120 and protrudes from the magnetic conductive member 120. The magnetic conductive member 120 and the spring pin 200 in the connector are connected with a circuit board or a cable, so that the spring pin 200 serves as a positive pole and the magnetic conductive member 120 serves as a negative pole, which are connected to the charging end of the electronic device. The spring pin 200 and the magnetic conductive member 120 are coaxially arranged. , so that when the spring pin 200 is connected to the charging terminal on the electronic device, the spring pin 200 abuts against the negative pole of the charging terminal on the electronic device, and the positive pole of the charging terminal on the electronic device contacts the magnetic conductive member 120, and the magnetic conductive member 120 is arranged in an annular shape, so that the positive pole of the charging terminal on the electronic device can be connected to the magnetic conductive member 120 no matter how it rotates, and there is no need to rotate to find a fixed angle to achieve charging. Through the annular magnetic conductive member 120 and the coaxially arranged spring pin 200, 360° rotation contact charging is achieved; in addition, the magnet 110 contacts the magnetic conductive member 120, so that the magnetic conductive member 120 has a magnetic attraction effect, and is magnetically connected to the charging terminal of the electronic device, which can achieve quick connection and separation, thereby improving the convenience of charging.

[0038] In addition, the charging end of the electronic device is preferably configured as a magnet and a metal end with opposite magnetic properties to the magnet 110 in the connector, so that the magnetic attraction effect is better due to the attraction between opposite poles.

[0039] Among them, the spring needle 200 has a needle, a spring and a needle tube, and charging is achieved through needle contact. One end of the needle of the spring needle 200 protrudes from the magnetic conductive part 120, and the protruding needle is inserted into the female connector of the electronic device. The positive pole of the charging end of the electronic device is connected to the magnetic conductive part 120 to achieve connection between the positive and negative poles.

[0040] It should be noted that the cross-section of the magnet 110 can be square or circular, and the spring needle 200 and the magnet 110 can be coaxially arranged or not, as long as the magnet 110 can be in contact with the magnetic conductive part 120 and the magnetic field can be transmitted to the magnetic conductive part 120 so that the magnetic conductive part 120 has a magnetic attraction. In the specific implementation of this embodiment, the magnet 110 is in a cylindrical state and is coaxially arranged with the magnetic conductive part 120, so that the end of the magnetic conductive part 120 away from the magnet 110 has a balanced magnetic attraction, making the magnetic attraction connection more stable, and the needle end of the spring needle 200 passes through the magnet 110 and the magnetic conductive part 120 in turn, and the needle end protrudes from the magnetic conductive part 120, and cooperates with the annular magnetic conductive part 120 to achieve 360° rotation and contact charging at any angle.

[0041] Optionally, the first connector 100 further includes a conductive member 130 , and the conductive member 130 is used to connect the magnetic conductive member 120 and a cable or a circuit board to achieve electrical conduction.

[0042] In this embodiment, the conductive member 130 is welded to the magnetic member 120 to achieve connection with the magnetic member 120. In addition, the conductive member 130 is also connected to a cable or a circuit board to achieve circuit conduction and conduction, so that the magnetic member 120 is energized. The magnetic member 120 and the spring pin 200 serve as the positive and negative ends of charging respectively. The conductive member 130 includes a first part and a second part. The first part is arranged at one end of the magnet 110 and welded to the magnetic member 120. The second part is arranged on the outer periphery of the magnet 110 and arranged along the axial direction of the magnet 110, leading to the end of the magnet 110 away from the magnetic member 120, and communicating with the cable or the circuit board to achieve current conduction between the conductive member 130 and the magnetic member 120. The first part and the second part are integrally formed, and the second part can be in the form of a sheet, which is arranged along the axial direction of the magnet 110, or can be arranged around the outer periphery of the magnet 110. It is preferred to set the second part in the form of a sheet, which not only realizes current conduction, but also saves materials and reduces costs. Circuit conduction can be achieved without large-area connection, so that the magnetic member 120 is connected as a negative pole for charging.

[0043] In the specific implementation process, the first part can be set to a ring shape, and the inner circle diameter of the first part is larger than the inner circle diameter of the magnetic component 120 and smaller than the outer circle diameter of the magnetic component 120. The magnetic component 120 can not only contact with the conductive component 130 for welding to conduct current, but also contact with the magnet 110 to form magnetic attraction.

[0044] Furthermore, the magnetic charging connector further includes a first plastic component 300 . The first plastic component 300 is disposed along the axial direction of the spring pin 200 and disposed on the outer periphery of the spring pin 200 to isolate the spring pin 200 from the magnetic conductive component 120 .

[0045] In this embodiment, if Figure 3As shown, the first plastic part 300 is disposed on the periphery of the spring pin 200 and along the axial direction of the spring pin 200. The first plastic part 300 isolates the spring pin 200 from contact with the magnetic conductive part 120 to avoid short circuit between the positive and negative electrodes.

[0046] Optionally, an end of the first plastic component 300 close to the needle head of the spring needle 200 is lower than the magnetic conductive component 120 .

[0047] In this embodiment, the first plastic part 300 is lower than the magnetic conductive part 120, that is, the distance between the end of the first plastic part 300 and the needle is greater than the distance between the magnetic conductive part 120 and the needle, which can prevent poor contact when pairing with the electronic device.

[0048] Furthermore, the magnetic charging connector further includes a second plastic component 310 , and the second plastic component 310 is disposed on the outer periphery of the magnet 110 and on a side of the magnet 110 away from the magnetic conductive component 120 .

[0049] In this embodiment, if Figure 3 As shown, the second plastic part 310 is arranged on the periphery of the magnet 110 and the end of the magnet 110 away from the magnetic conductive part 120. The second plastic part 310 covers the magnet 110 and the conductive part 130 to prevent the magnet 110 from leaking out and corroding. In addition, the end of the conductive part 130 away from the magnetic conductive part 120 passes through the second plastic part 310 to be connected to the cable or circuit board, forming an interference fit with the second plastic part 310, which can prevent the magnet 110 and the magnetic conductive part 120 from being sucked out.

[0050] In addition, if Figure 4 As shown, the second plastic part 310 is cylindrical and can be set in the cylindrical cavity to install the magnetic charging connector; Figure 5 As shown, a connecting piece 311 is protrudingly provided on the outer periphery of the second plastic part 310, so that the magnetic charging connector can be installed through the connecting piece 311, which has a wide range of applications.

[0051] Figure 4 and Figure 5 It is shown that the conductive member 130 and the spring pin 200 pass through the second plastic member 310 to connect with the cable. The conductive member 130 and the spring pin 200 may also be connected with a circuit board (not shown).

[0052] Optionally, the first plastic component 300 and the second plastic component 310 are integrally formed.

[0053] In this embodiment, the first plastic part 300 and the second plastic part 310 are integrally formed, which can prevent the magnet 110 from being exposed and causing corrosion.

[0054] Furthermore, the magnetic charging connector also includes a top cover 400 and an adhesive component. The top cover 400 is arranged at one end of the magnet 110 where the magnetic conductive component 120 is provided, and is connected to the second plastic component 310. A glue storage groove 401 is provided on the side of the top cover 400 facing away from the magnet 110. The adhesive component is arranged in the glue storage groove 401 and connects the top cover 400 and the magnetic conductive component 120.

[0055] In this embodiment, if Figure 1 - Figure 3 As shown, the top cover 400 is arranged at one end of the magnet 110 where the magnetic conductive part 120 is provided, and is fixedly connected to the second plastic part 310. A receiving cavity is formed inside the top cover 400, the second plastic part 310 and the magnetic conductive part 120. The magnet 110 is located in the receiving cavity. A glue storage groove 401 is provided on one side of the top cover 400 close to the magnetic conductive part 120. An adhesive is provided in the glue storage groove 401. The top cover 400 and the magnetic conductive part 120 are connected by the adhesive, so that the interior of the receiving cavity is sealed, which can prevent the top cover 400 from loosening and prevent liquid from flowing into the interior of the receiving cavity to cause corrosion of the magnet 110, thereby improving the corrosion resistance of the structure.

[0056] The top cover 400 is made of plastic, and the adhesive member can be a sticky substance such as glue.

[0057] Optionally, the magnetic conductive member 120 and the conductive member 130 are both made of metal, and the magnetic conductive member 120 and the conductive member 130 are made of different metal materials;

[0058] And / or, a metal coating is disposed on the outside of the magnetic conductive component 120 and the conductive component 130 , and the metal coating of the magnetic conductive component 120 and the metal coating of the conductive component 130 are made of different materials.

[0059] In the present embodiment, the magnetic member 120 and the conductive member 130 are both made of metal material. The conductive and magnetic conductive effects of the metal material are good. The magnetic field is transferred by the contact between the magnetic member 120 and the magnet 110, and magnetic attraction is achieved through the magnetic member 120. In addition, the cable or circuit board is connected through the conductive member 130 and connected to the magnetic member 120 to achieve current conduction. In addition, the metal materials of the magnetic member 120 and the conductive member 130 are different. Since the magnetic member 120 is exposed to the outside, beautiful metal can be selected, so the cost is high, while the conductive member 130 is inside, low-cost metal can be selected, thereby reducing the production cost.

[0060] In another embodiment, a metal coating is provided on the outside of the magnetic conductive component 120 and the conductive component 130, and the metal coating is made of different materials. The metal coating of the magnetic conductive component 120 is adsorbed onto the magnet 110 to form a magnetic attraction, and the metal coating of the conductive component 130 conducts electricity. Similarly, the metal coating of the conductive component 130 can be made of low-cost metal to reduce production costs.
