[0014] In one embodiment, the power supply detection circuit further includes a diode, the anode of the diode D1 being connected to the resistor R4, the drain of the field-effect transistor Q4, the ground terminal of the third port, and the resistor R3, respectively, and the cathode of the diode being connected to the VBUSIN terminal.

[0015] In one embodiment, the Type-C connector circuit further includes a voltage regulator circuit, and the VBUSIN terminal is connected to the VDD terminal of the PD processor via the voltage regulator circuit to provide a stable DC power supply to the PD processor;

[0031] The preferred embodiments of this application will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this application can be more easily understood by those skilled in the art, thereby providing a clearer definition of the scope of protection of this application.

[0032] Please refer to the diagrams, where the same component symbols represent the same components. The principles of this application are illustrated by way of example implementation in a suitable computing environment. The following description is based on the specific embodiments of this application exemplified, and should not be construed as limiting other specific embodiments not detailed herein.

[0033] Please see Figure 1 The figure shows the structure of the Type-C connector circuit provided in an embodiment of this application.

[0034] like Figure 1 As shown, the Type-C connector circuit 5 includes a power supply detection circuit 51, a switch module 511, an enable control module 512, and a PD processor 52.

[0035] The Type-C connector circuit 5 includes a first port and a second port for connecting external devices. The first and second ports are used to connect power input devices to provide charging power to the electronic device 4. The input current of the first port is less than that of the second port, allowing for high-current charging at the second port. The power supply detection circuit 51 in the Type-C connector circuit 5 includes a switch module 511 and an enable module 512. The switch module 511 is connected to both the first and second ports to control the current of the power input. The Type-C connector circuit 5 also includes a PD processor 52, which is connected to a third port and a fourth port. The third and fourth ports are used to connect the audio headset 3 and the electronic device 4, respectively, and are connected for communication. The PD processor 52 is also connected to the power supply detection circuit 51. Based on the connection status of the second port, it generates an enable signal and transmits it to the enable control module 512. The enable control module 512 uses the enable signal to control the switch module 511, ensuring that the input current from the second port is supplied to the third and fourth ports. This achieves compatibility between charging and audio functions of the electronic device 4, improving the ease of use.

[0036] In one embodiment, the first port and the second port can be used to connect a computer 2 and a high-current charger 1, respectively. The first port and the second port can also connect to other power input devices, such as a power bank or other terminals with power output functions. Furthermore, the first port and the second port can be Type-C ports supporting the USB protocol to facilitate connection to external power supply devices with Type-C plugs, or other ports that can be used for power supply. This application does not limit the implementation of the above structure.

[0037] The power supply detection circuit 51 of the Type-C connector circuit 5 is used to identify power insertion. It identifies the insertion based on the electrical signals transmitted by the pins of the first port and the second port, and transmits the signals to the PD processor 52. Together with the enable control module 512 and the switch module 511, it realizes the switching of large current in the circuit.

[0038] The working principle of the Type-C connector circuit 5 in this application is as follows: After the external device connector is inserted, the power supply detection circuit 51 can confirm the power supply insertion identification by changing the level of the pin connected to the port according to the insertion connection status of the first port or the second port. At the same time, the PD processor 52 identifies the power supply protocol and sends an enable signal to the enable control module 512. The enable control module 512, according to the enable signal, cooperates with the switch module 511 to realize high-current charging of the electronic device 4. The PD processor 52 establishes a data transmission path between the electronic device 4 and the audio headset 3, while maintaining the charging path of the charger 1 or the computer 2 to the system, so that the electronic device 4 can be charged while the audio headset 3 is used.

[0039] It is understandable that the specific circuits and implementation methods of the power supply detection circuit 51, PD processor 52, first port, and second port can refer to existing designs, as long as the above functions can be achieved.

[0040] Please see Figure 2 The figure illustrates the structure of the Type-C connector circuit 5 provided in this application, where the port adopts a Type-C interface.

[0041] like Figure 2 As shown, the first and second ports of the Type-C connector circuit 5 share pins with the Type-C interface. The voltage is supplied to the entire circuit through the VBUS terminal of the Type-C interface, and the voltage flows from the VBUS terminal of the second port to the VBUS2 pin.

[0042] The above structure reduces the space occupied in the connector, and a single Type-C interface can integrate multiple functions such as charging transmission, data transmission, and audio transmission, which is conducive to the thinner and lighter design of the connector.

[0043] Please see Figure 3 The figure shows the structure of the power supply detection circuit 51 of the Type-C connector circuit 5 provided in the embodiment of this application.

[0044] like Figure 3As shown, the power supply detection circuit 51 includes a switch module 511 and an enable control module 512. The enable control module 512 is connected to the VBEN terminal of the PD processor 52 via the VBUS_EN pin. The enable signal generated by the PD processor 52 is transmitted to the VBUS_EN pin, which is connected to the gate of the field-effect transistor Q1 of the enable control module 512. The drain of the field-effect transistor Q1 is connected to the VBUSIN terminal of the fourth port and the switch module 511, respectively. The source of the field-effect transistor Q1 is connected to the ground. The field-effect transistor Q1 is used to turn on according to the enable signal, pulling down the level at the drain of the field-effect transistor Q1, so that the switch module 511 can switch the control according to the change of the level here.

[0045] The enable control module 512 further includes resistors R1 and R2. One end of resistor R1 is connected between the VBUS_EN pin and the gate of the field-effect transistor Q1, and the other end of resistor R1 is connected between the source and ground of the field-effect transistor Q1. Resistor R1 connects the gate of the field-effect transistor Q1 to ground, acting as a pull-down resistor. When there is no input signal on the VBUS_EN pin, resistor R1 can pull the gate voltage of the field-effect transistor Q1 to a low level (close to ground potential), ensuring that the field-effect transistor Q1 is reliably turned off and avoiding false turn-on of the field-effect transistor Q1 due to uncertain gate potential. One end of resistor R2 is connected to the source of the field-effect transistor Q1, resistor R1, and ground, respectively. The other end of resistor R2 is connected to the switch module 511 and the C1DT terminal of the PD processor 52 via the VBUS_DET pin.

[0046] The switch module 511 is connected to the VBUS2 pin to supply power to the power supply detection circuit 51. The switch module 511 includes field-effect transistors Q2, Q3, and Q4, resistors R3 and R4. The VBUS2 pin is connected to the drain of field-effect transistors Q2 and Q3, while the VBUSIN terminal of the fourth port is connected to the source of field-effect transistors Q2, Q3, and Q4, respectively. The drain of field-effect transistor Q1 is also connected to the gate of field-effect transistors Q2 and Q4. When field-effect transistor Q1 is turned on, it pulls down field-effect transistors Q2 and Q4, turning them on and allowing the voltage of the VBUS2 pin to flow into the VBUSIN terminal of the fourth port, thereby charging the electronic device 4. Similarly, the gate of the field-effect transistor Q3, which is also connected to the VBUS2 pin, is connected to the drain of the field-effect transistor Q4 and the ground terminal of the third port via the resistor R4. The ground terminal of the third port is connected to the drain of the field-effect transistor Q4, the resistor R3 and the resistor R4 via the VBUS1- pin. The resistor R4 plays the role of voltage divider and current limiter in the circuit. The resistor R4 is connected in series with the gate of the field-effect transistor Q3, which can limit the current flowing into the gate of the field-effect transistor Q3 and prevent excessive current from flowing into the gate and damaging the field-effect transistor Q3.

[0047] Furthermore, the power supply detection circuit 51 also includes a resistor R5 and a diode D1. One end of R5 is connected to the gate of the field-effect transistor Q2 and the gate of the field-effect transistor Q4, respectively, and the other end is connected to the source of the field-effect transistor Q2 and the source of the field-effect transistor Q4, respectively, so that the drain of the field-effect transistor Q1 is connected to the VBUSIN terminal of the fourth port through the resistor R5. The resistor R5 is also the bias resistor of the field-effect transistors Q2 and Q4.

[0048] The positive terminal of diode D1 is connected to resistor R4, the drain of MOSFET Q4, the ground terminal of the third port, and resistor R3, respectively. The negative terminal of diode D2 is connected to the VBUSIN terminal of the fourth port. Diode D1 is used in conjunction with resistor R4 to prevent current from entering the gate of MOSFET Q3 and also to provide voltage isolation for the VBUSIN terminal.

[0049] The aforementioned power supply detection circuit 51 utilizes a switch module 511 and an enable control module 512, along with a PD processor 52, to achieve insertion identification and charging judgment. Moreover, this circuit uses only basic components, making it relatively inexpensive and saving hardware costs, thereby reducing product costs.

[0050] Please see Figure 4 The figure illustrates the structure of the voltage regulator circuit provided in an embodiment of this application.

[0051] like Figure 4 As shown, the Type-C connector circuit 5 also includes a voltage regulator circuit. The VBUSIN terminal is connected to the VDD terminal of the PD processor 52 via the voltage regulator circuit to provide a stable DC power supply to the PD processor 52. The voltage regulator circuit includes a voltage regulator U1, capacitors C1, C2, and C3. Pin 3 of the voltage regulator U1 is the input terminal, pin 2 of the voltage regulator U1 is the output terminal, and pin 1 of the voltage regulator U1 is the ground terminal.

[0052] In this circuit, capacitor C1 is located at the input of voltage regulator U1, while capacitors C2 and C3 are located at the output of voltage regulator U1. All three capacitors are grounded and serve as filters in the circuit. Capacitor C1 filters out low-frequency ripple and interference at the input, capacitor C2 filters out low-frequency noise at the output to reduce the impact of low-frequency ripple on the downstream circuit, and capacitor C3 utilizes the high-frequency characteristics of a small-capacity capacitor to filter out high-frequency interference at the output. The three resistors, together with voltage regulator U1, provide a stable 5V output voltage to PD processor 52 for powering PD processor 52. Preferably, voltage regulator U1 in this circuit is an HT7550, and the voltage regulator circuit outputs a 5V voltage.

[0053] The above structure allows for the output of a stable voltage in the circuit, which can then be used for the PD processor 52 or other chips.

[0054] Please see Figure 5 The figure illustrates the structure of the PD processor provided in an embodiment of this application.

[0055] like Figure 5 As shown, the 5V output of the voltage regulator circuit is connected to the VDD terminal of the PD processor 52 via resistor R6. Resistor R6 is connected in series between the output terminal and the VDD terminal of the voltage regulator circuit. Resistor R6 limits the current flowing into the chip, preventing damage to the internal circuitry due to excessive current, thus protecting the chip. Additionally, capacitor C4 is located at the VDD terminal of the PD processor 52, connected between the VDD terminal and the ground terminal. Capacitor C4 filters out high-frequency noise and ripple on the power line, preventing interference signals from entering the PD processor 52 and affecting its normal operation. Preferably, the PD processor 52 is an LDR6023SS.

[0056] The input terminal of the PD processor 52 is formed by the voltage regulator circuit, resistor R6, and capacitor C4, in conjunction with... Figure 5 The connection relationships and voltage regulation circuits in the circuit ensure that the PD processor 52 can input a stable voltage, thus ensuring the stable operation of the Type-C connector circuit.

[0057] Please see Figure 6 The figure illustrates the structure of the chip circuit provided in an embodiment of this application.

[0058] like Figure 6 The Type-C connector circuit also includes a chip circuit, in which the 5V voltage output by the aforementioned voltage regulator circuit also flows to the chip circuit. The chip circuit includes resistors R7 and R8 and a field-effect transistor Q5. One end of resistor R7 is connected to the REV3 terminal of the PD processor 52 via the PT_POW pin, and the other end is connected to the gate of resistor R8 and the field-effect transistor Q5 respectively. The other end of resistor R8 is connected to the output terminal of the voltage regulator circuit and the source of the field-effect transistor Q5 respectively. The drain of the field-effect transistor is connected to the SOC chip via the RT_5V pin.

[0059] This chip circuit enables better audio processing. Resistor R7 limits the current to the MOSFET Q5, preventing large current surges to its gate. Resistor R8 acts as a pull-down resistor; when there is no signal input to the RT_POW pin, resistor R8 pulls the gate voltage of MOSFET Q5 low, ensuring reliable cutoff. Preferably, the SOC chip is an ATS3031.

[0060] Please see Figure 7 The figure illustrates the structure of the protection circuit provided in an embodiment of this application.

[0061] like Figure 7As shown, the Type-C connector circuit 5 also includes a protection circuit 54, which includes resistors R9 and R10 and capacitor C5. One end of resistor R9 is connected to the outer shell of the second port, and the other end is connected to resistor R10. Capacitor C5 is connected in parallel with resistor R9, and the other end of resistor R10 is grounded.

[0062] The protection circuit 54 is mainly used for electrostatic discharge protection of the equipment casing. It provides a high-frequency discharge path for static electricity through capacitor C5, quickly conducting static electricity to ground. At the same time, resistors R9 and R10 limit the electrostatic discharge current, preventing large current from impacting the system circuit and protecting internal components. Moreover, resistors R9 and R10 have high impedance to low-frequency signals, blocking low-frequency interference.

[0063] Please see Figure 8 The figure illustrates the structure of the magnetic Type-C connector provided in an embodiment of this application.

[0064] like Figure 8 As shown, the magnetic Type-C connector includes the aforementioned Type-C connector circuit 5. The magnetic Type-C connector is provided with a pogo pin elastic pin assembly 11 for electrical connection with the second port. A magnetic component is provided in the housing near the pogo pin elastic pin assembly 11. The pogo pin elastic pin assembly 11 is plugged into and engaged with the external charger 1, and the magnetic component is attracted to the plug of the charger 1, so that the electronic device 4 can be conveniently connected during charging via the pogo pin elastic pin assembly 11.

[0065] Repeated physical plugging and unplugging of traditional Type-C interface devices can easily cause interface wear, shorten the device's lifespan, and increase the cost of replacing devices or interfaces for users. Moreover, in certain environments, such as on a bumpy car or during movement, the stability of conventional interfaces is poor, easily becoming loose, leading to charging or audio transmission interruptions. The magnetic attachment component, combined with the pogo pin elastic ejector assembly 11, can enhance the stability during insertion. This magnetic Type-C connector also has a Type-A interface 21 for electrical connection to the first port. Computer 2 connects to this Type-A interface 21 via a data cable, allowing computer 2 to connect to electronic device 4 through the magnetic Type-C connector, facilitating data transmission and communication between electronic device 4 and computer 2.

[0066] Preferably, the magnetic Type-C connector is connected to the electronic device 4 through the Type-C interface 31 of the audio headset 3. The pogo pin elastic pin assembly 11 and the Type-A interface 21 are both electrically connected to the corresponding pins of the Type-C interface 31, sharing the Type-C interface 31 of the audio headset 3, and using the Type-C interface 31 to connect to the electronic device 4.

[0067] It is worth noting that electronic device 4 can be a mobile phone, tablet, smartwatch, or other similar device. The magnetic Type-C connector is an accessory that works with the Type-C male connector of the audio headset 3. The Type-C interface 31 connects to electronic device 4, audio headset 3, the Type-A interface 21 of the first port, the pogo pin elastic ejector assembly 11 of the second port, and the Type-C connector circuit 5. The Type-C interface 31 connects to the power supply detection circuit 51, enabling the power supply detection circuit 51 to identify and determine the insertion of a power source. It then supplies power to the PD processor 52 through the voltage regulator circuit 53. The PD processor 52 sends an enable signal to the power supply detection circuit 51, allowing a large current to pass through and be transmitted to electronic device 4 via the Type-C interface 31. The PD processor 52 also supplies power to the chip circuit 55, enabling the audio headset 3 to be used while charging. A protection circuit 54 is also provided at the Type-C interface to protect internal components.

[0068] In addition, in some preferred embodiments, the pogo pin spring assembly can be located on either side of the housing of the magnetic Type-C connector, while the Type-A interface is located on the side adjacent to the pogo pin spring assembly. When the device is plugged in, the wire harnesses are located on the same side without occupying a large space. The adjacent interfaces can shorten the electrical connection path between the two, reduce the signal transmission distance, and make plugging convenient. There is no need to search for the interface at different positions on the connector, which is conducive to the compact design of the magnetic Type-C connector.
