[0003] In order to solve the communication connection between the power-consuming equipment and the charging equipment, the charging connector of related technologies has chosen to place communication terminals on the charging connector. However, the layout of the positive terminal, negative terminal and communication terminals is generally unreasonable, resulting in a complex structure of the charging connector, poor plugging convenience, short service life and high manufacturing cost. Utility Model Content

[0005] The technical solution is as follows:

[0006] On one hand, a charging connector is provided, the charging connector comprising: a male connector assembly and a female connector assembly;

[0007] The male connector assembly includes a first insulating shell, a metal probe, a first metal plate, and a second metal plate;

[0008] The first insulating shell includes a first inner sleeve portion, the metal probe is coaxially arranged inside the first inner sleeve portion, and the first metal sheet and the second metal sheet are circumferentially spaced on the outer wall of the first inner sleeve portion;

[0009] The female connector assembly includes a second insulating shell, a metal sleeve, a first metal spring, and a second metal spring.

[0010] The second insulating shell includes a second outer tube portion, and the metal insert is coaxially arranged inside the second outer tube portion; the first metal spring and the second metal spring are circumferentially spaced on the inner wall of the second outer tube portion;

[0011] When the male connector assembly and the female connector assembly are plugged in, the first inner sleeve and the second outer sleeve are coaxially plugged in; the metal probe and the metal sleeve are plugged in to form a first electrical connection structure, the first metal piece and the first metal spring piece are elastically abutted to form a second electrical connection structure, and the second metal piece and the second metal spring piece are elastically abutted to form a third electrical connection structure.

[0012] One of the first electrical connection structure, the second electrical connection structure, and the third electrical connection structure is used to realize the positive circuit connection, another is used to realize the negative circuit connection, and the third is used to realize the signal circuit connection.

[0013] In this embodiment of the charging connector, the first insulating shell serves as the insulating support for the male connector assembly. A metal probe is arranged on the axis of the first inner sleeve portion of the first insulating shell. A first metal piece and a second metal piece are respectively arranged on the outer wall of the first inner sleeve portion. The three conductive components are mutually insulated, giving the male connector assembly the advantages of simple structure and convenient assembly. Similarly, the second insulating shell serves as the insulating support for the female connector assembly. A metal sleeve is arranged on the axis of the second outer sleeve portion of the second insulating shell. A first metal spring and a second metal spring are respectively arranged on the inner wall of the second outer sleeve portion. The three conductive components are mutually insulated using the first inner sleeve portion. The female connector assembly also has the advantages of simple structure and convenient assembly. During the insertion of the male and female connector assemblies, the metal probe and metal sleeve are inserted axially, and the first and second metal springs slide against the first and second metal pieces respectively. The engagement and disengagement of the three electrical connection structures do not hinder the insertion and removal activities of the male and female connector assemblies. The charging connector has good insertion convenience, and the wear during the engagement of the three electrical connection structures is minimal, which helps to improve the service life of the charging connector.

[0014] In some possible implementations, the first electrical connection structure is used to implement a positive circuit connection, the second electrical connection structure is used to implement a negative circuit connection, and the third electrical connection structure is used to implement a signal circuit connection.

[0015] With the above arrangement, the charging connector can achieve electrical conduction of the positive circuit, negative circuit and signal circuit, thus meeting the functional requirements of the charging connector.

[0016] In some possible implementations, the first metal spring and the second metal spring respectively include a crown-shaped elastic part, a snap-fit ​​fixing part, and a wiring part;

[0017] The coronal elastic part is located on the inner wall of the second outer sleeve part, the snap-fit ​​fixing part is located on the edge of the coronal elastic part, and the middle part of the coronal elastic part protrudes towards the axis of the second outer sleeve part; the snap-fit ​​fixing part is used to snap and fix the edge of the coronal elastic part to the inner wall of the second outer sleeve part, the wiring part is connected to the coronal elastic part, and the wiring part is used to connect to the external circuit.

[0018] With the above arrangement, the first and second metal springs are connected to the external circuit via the wiring part, and the crown elastic part is used to elastically press against the first or second metal piece. The crown elastic part has a larger contact area, which can meet the requirements of high current transmission, and has better contact stability and longer service life.

[0020] With the above arrangement, the multiple elastic arms in the coronal elastic part can elastically abut against the first metal sheet or the second metal sheet respectively, realizing multi-point contact, which can significantly improve the stability of the connection and increase the current carrying area of ​​the circuit structure; the elastic arms in the coronal elastic part have fewer insertion and removal variables during operation, which can significantly improve the service life of the first metal spring, maintain a stable connection under high-frequency vibration conditions, eliminate the risk of instantaneous disconnection, and have a long seismic life.

[0021] In some possible implementations, the central angle α corresponding to the circumferential dimension of the coronal elastic portion along the second outer sleeve portion ranges from 30 to 50 degrees.

[0022] When the value of the central angle α of the coronal elastic part meets the above-mentioned range, the coronal elastic part has good contact stability and current-carrying area, and can maintain a stable connection under high-frequency vibration conditions, without the risk of instantaneous breakage, and has a long seismic service life.

[0023] In some possible implementations, the first metal sheet and the second metal sheet are arranged on the outer wall of the first inner sleeve at a 180-degree interval;

[0025] With the above arrangement, the first metal sheet and the second metal sheet are arranged 180 degrees apart, which has better insulation performance. Correspondingly, the first metal spring and the second metal spring are also arranged 180 degrees apart, which also has better insulation performance.

[0026] In some possible implementations, the first insulating shell further includes a first outer sleeve portion and a first base portion, the first inner sleeve portion is coaxially arranged inside the first outer sleeve portion, the first axial first ends of the first inner sleeve portion and the first outer sleeve portion are respectively connected to the first base portion, and the second axial ends of the first inner sleeve portion and the first outer sleeve portion are open.

[0027] The metal probe, the first metal sheet, and the second metal sheet extend axially to one end of the first base portion facing away from the first inner sleeve portion.

[0028] With the above arrangement, the first inner sleeve and the first and second metal pieces on its outer wall are respectively wrapped by the first outer sleeve, which can play a good protective role and help improve the sealing protection of the charging connector in the plugging state.

[0029] In some possible implementations, the second insulating shell includes a second inner sleeve portion and a second base portion, the second inner sleeve portion being coaxially arranged inside the second outer sleeve portion, the second axial ends of the second inner sleeve portion and the second outer sleeve portion being respectively connected to the second base portion, and the second axial ends of the second inner sleeve portion and the second outer sleeve portion being open;

[0030] The metal sleeve, the first metal spring, and the second metal spring each extend axially to one end of the second base portion facing away from the second inner sleeve portion;

[0031] The second inner sleeve is inserted into the first inner sleeve, the second outer sleeve is inserted into the first outer sleeve, and the first inner sleeve is located between the second inner sleeve and the second outer sleeve.

[0032] With the above arrangement, after the male connector and female connector are plugged in, the first insulating shell and the second insulating shell are nested together to form a multi-layered connection from the outside to the inside, consisting of the first outer sleeve, the second outer sleeve, the first inner sleeve, and the second inner sleeve. This results in better plugging performance and meets the safety requirements of charging connectors in the field of fast charging products.

[0033] In some possible implementations, the first insulating shell further includes an end plate portion that is perpendicular to the axial direction of the first outer sleeve portion and is connected to the outer peripheral wall of the axial second end of the first outer sleeve portion.

[0034] With the above arrangement, the first insulating shell can be fixedly connected to the charging device or the electrical device using the end plate, thereby realizing the fixed connection between the male connector assembly and the charging device or the electrical device.

[0035] In some possible implementations, the second insulating shell further includes a limiting flange that is perpendicular to the axial direction of the second outer sleeve portion and connected to the outer peripheral wall of the second axial end of the second outer sleeve portion.

[0036] With the above arrangement, when the second insulating shell and the first insulating shell are inserted into each other, the limiting flange can be used to abut against the port of the first insulating shell to realize the insertion limit of the male and female components, and prevent excessive insertion from causing damage to the male or female components.

[0060] On the one hand, combined with Figures 1 to 4 As shown, this embodiment provides a charging connector, which includes a male connector assembly 1 and a female connector assembly 2.

[0061] The male connector assembly 1 includes a first insulating shell 11, a metal probe 12, a first metal piece 13, and a second metal piece 14.

The first metal piece 13 and the second metal piece 14 are respectively arranged on the outer wall of the first inner sleeve portion 111. The three conductive components are mutually insulated, and the male connector assembly 1 has the advantages of simple structure and convenient assembly. The second insulating shell 21 serves as the insulating support for the female connector assembly 2. The metal sleeve 22 is arranged on the axis of the second outer sleeve portion 211 of the second insulating shell 21.

The charging connector has good insertion convenience, and the wear during the engagement of the three electrical connection structures is small, which is conducive to improving the service life of the charging connector.

[0067] In some possible implementation schemes, the communication signals transmitted by the signal circuit include connection status signals and charging status signals (such as voltage signals and current signals), among which the connection status signals and charging status signals can be used to realize the on-off control of the positive and negative circuits.

[0068] In some possible implementations, the first electrical connection structure is used to implement the positive circuit connection, the second electrical connection structure is used to implement the negative circuit connection, and the third electrical connection structure is used to implement the signal circuit connection.

[0071] The coronal elastic part 231 is located on the inner wall of the second outer sleeve part 211, and the snap-fit ​​fixing part 232 is located on the edge of the coronal elastic part 231. The middle part of the coronal elastic part 231 protrudes towards the axis of the second outer sleeve part 211. The snap-fit ​​fixing part 232 is used to snap and fix the edge of the coronal elastic part 231 on the inner wall of the second outer sleeve part 211. The wiring part 233 is connected to the coronal elastic part 231 and is used to connect to the external circuit.

The crown elastic part 231 has a larger contact area, which can meet the requirements of high current transmission, and has better contact stability and longer service life. The crown elastic part 231 is fixed to the inner wall of the first outer sleeve part 112 by the snap-fit ​​fixing part 232. The structure is simple, the reliability is higher, and the possibility of movement under the action of the insertion and extraction force of the male connector assembly 1 and the female connector assembly 2 is smaller.
