[0002] Type-C electrical connectors are increasingly used in electronic products. Currently, the CC1 / CC2 wires in Type-C USB (Universal Serial Bus) female connectors require a resistor to ground. These two resistors play an important role in the communication protocol and power management of the Type-C interface.

[0003] The shortcoming is that the above-mentioned resistors are indispensable, which means that many consumer electronic products must add these two resistors to the circuit board of the electronic products in order to realize the charging function. This not only increases the requirements for the stacking structure of the circuit board, but also brings more steps to the manufacturing and processing of the circuit board. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] The terms "first," "second," and the like in this application are used to distinguish between different objects, rather than to describe a particular order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to the process, method, or device.

[0024] TYPE-C electrical connectors are increasingly used in electronic products. Currently, the CC1 / CC2 wires in the TYPE-C USB female connector require a resistor to ground. These two resistors play an important role in the communication protocol and power management of the TYPE-C interface.

[0025] The disadvantage is that the above resistors are indispensable, which means that many consumer electronic products must add these two resistors to the circuit board to achieve the charging function. This not only increases the requirements for the stacking structure of the circuit board, but also brings more steps to the manufacturing process of the circuit board. Specifically, Figure 1 As shown, the USB socket 100 is provided with two GND pins, two VBUS pins, and CC1 and CC2. Because CC1 and CC2 need to be grounded through resistors. Therefore, corresponding detection resistors (resistors R1 and R2) need to be set on the circuit board 200. One end of the resistor R1 and the resistor R2 is grounded so that when the USB socket 100 is connected to the circuit board 200, CC1 and CC2 are connected to the resistor R1 and the resistor R2 respectively, and grounded through the resistor R1 and the resistor R2.

[0026] Based on this, the present application proposes to set the detection resistor that must be connected to the CC pins (CC1 and CC2) in the USB socket 100. Compared with the electronic product equipped with the USB socket 100, the circuit board 200 of the electronic product does not need to be equipped with a detection resistor again. This not only reduces the requirements for the stacking structure of the circuit board 200, but also reduces the manufacturing and processing steps of the circuit board 200. Furthermore, the circuit board 200 can be more miniaturized while reducing the setting of the detection resistor.

[0027] Please refer to the following for details: Figure 2 , Figure 2 This is a schematic diagram of the structure of an embodiment of a USB female connector provided by the present application. The USB is of TYPE-C type. The USB female connector 100 includes: a housing (not shown) and a pin module.

[0028] The pin module is disposed within the housing and includes CC pins (CC1 and CC2) and sense resistors (R1 and R2), with the CC pins connected to the sense resistors. Furthermore, the pin module may also include a VBUS pin and a GND pin (ground pin). In some embodiments, the pin module may include only one CC pin and one sense resistor.

[0029] In some embodiments, the USB female connector 100 includes a first end and a second end. The first end is used to plug into a USB male connector, and the second end is used to connect to a corresponding circuit board of an electronic device (such as the circuit board 200 described above). A pin module also corresponds to the first and second ends, wherein the pins on the first end of the pin module correspond to the pins on the USB male connector, and the pins on the second end of the pin module correspond to the pins on the circuit board.

[0030] The pins at the first and second ends of the pin module are arranged correspondingly. For example, the CC pin has its first end located at the first end of the pin module, and its second end is connected to a detection resistor and then leads out of the second end of the pin module through the detection resistor.

[0031] In some embodiments, the detection resistor may be a chip resistor, so that the detection resistor is small in size and can be disposed inside the housing.

[0032] In some embodiments, the USB receptacle 100 includes not only a housing and a pin module but also an associated insulator. The pin module can be injection molded onto the insulator. In other words, a corresponding receiving slot can be provided on the insulator, and a detection resistor can be placed within the receiving slot, thereby eliminating the need to increase the size of the USB receptacle 100.

[0033] In some embodiments, the number of pins of the USB female socket 100 can be set according to actual needs, such as 24P (pin), 16P, 14P, 9P or 6P. Figure 2 As shown, the number of pins of the USB socket 100 of the present application is 6P.

[0034] In this embodiment, the detection resistor to which the CC pin must be connected is set in the USB socket 100. Compared with the electronic product provided with the USB socket 100, the circuit board of the electronic product does not need to be provided with a detection resistor again. This not only reduces the requirements for the stacking structure of the circuit board, but also reduces the manufacturing process of the circuit board. Furthermore, the circuit board can be more miniaturized under the premise of reducing the setting of the detection resistor.

[0035] Further, if Figure 2 As shown, the CC pins include CC1 (a first CC pin) and CC2 (a second CC pin), and the detection resistors include a first detection resistor R1 and a second detection resistor R2. CC1 is connected to the first detection resistor R1, and CC2 is connected to the second detection resistor R2. That is, CC1 can be led out from the second end of the USB receptacle 100 through the first detection resistor R1. CC2 can be led out from the second end of the USB receptacle 100 through the second detection resistor R2.

[0036] In some embodiments, the resistance of the first detection resistor R1 is 5.1K ohms.

[0037] In some embodiments, the resistance of the second detection resistor R2 is 5.1K ohms.

[0038] See Figure 3 , Figure 3 This is a schematic diagram of the structure of another embodiment of the USB female connector provided by the present application. The USB female connector is of TYPE-C type. The USB female connector 100 includes: a housing and a pin module.

[0039] The pin module is disposed within the housing, and includes CC pins (CC1 and CC2), detection resistors (R1 and R2), a ground pin, and a VBUS pin. The CC pin, detection resistor, and ground pin are connected in sequence. Furthermore, the pin module may further include a VBUS pin and a GND pin. In some embodiments, the lead wires of the two VBUS pins and the lead wire of the ground pin are disposed outside the housing.

[0040] like Figure 3 As shown, the second end of the pin module does not actually need to expose the CC pin. Because the first detection resistor R1 and the second detection resistor R2 need to be grounded, after the CC pin is connected to the detection resistor (for example, CC1 is connected to resistor R1, and CC2 is connected to resistor R2), the first detection resistor R1 and the second detection resistor R2 are connected to the ground pin. When the USB socket 100 is subsequently set up to correspond to the circuit board of the electronic product, the detection resistor can be grounded through the ground pin, eliminating the need to set up additional layout circuits corresponding to the resistor grounding on the circuit board of the electronic product.

[0041] That is, the pin module in the USB socket 100 further includes two VBUS pins and two ground pins; the USB socket 100 is coupled to the external circuit board only through the two VBUS pins and the two ground pins.

[0042] See Figure 4 , Figure 4 This is a schematic diagram of the structure of an embodiment of the electronic atomization device provided by the present application. The electronic atomization device 300 includes: a USB female socket 100 and a circuit board 200. The USB is TYPE-C.

[0043] The USB socket 100 includes: a shell and a pin module. The pin module is arranged in the shell, and the pin module includes CC pins (CC1 and CC2) and detection resistors (R1 and R2), and the CC pins are connected to the detection resistors. Furthermore, the pin module can also include two VBUS pins and two GND pins. The circuit board 200 is coupled to the CC pin of the pin module through the detection resistor. The lead wires of the two VBUS pins and the lead wire of the ground pin are arranged outside the shell for coupling with an external circuit board. That is, the USB socket 100 is coupled to the circuit board 200 only through two VBUS pins and two ground pins.

[0044] In some embodiments, the USB female connector 100 includes a first end and a second end. The first end is used to connect to a USB male connector, and the second end is used to connect to a corresponding circuit board 200 of an electronic device. A pin module also corresponds to the first and second ends, with the pins on the first end of the pin module corresponding to the pins on the USB male connector and the pins on the second end of the pin module corresponding to the pins on the circuit board 200.

[0045] The pins at the first and second ends of the pin module are arranged correspondingly. For example, the CC pin has its first end located at the first end of the pin module, and its second end is connected to a detection resistor and then leads out of the second end of the pin module through the detection resistor.

[0046] In some embodiments, the detection resistor may be a chip resistor, so that the detection resistor is small in size and can be disposed inside the housing.

[0047] In some embodiments, the USB receptacle 100 includes not only a housing and a pin module but also an associated insulator. The pin module can be injection molded onto the insulator. In other words, a corresponding receiving slot can be provided on the insulator, and a detection resistor can be placed within the receiving slot, thereby eliminating the need to increase the size of the USB receptacle 100.

[0048] In some embodiments, the number of pins of the USB female socket 100 can be set according to actual needs, such as 24P, 16P, 14P, 9P or 6P. Figure 2 As shown, the number of pins of the USB socket 100 of the present application is 6P.

[0049] Further, if Figure 4As shown, the CC pins include CC1 (a first CC pin) and CC2 (a second CC pin), and the detection resistors include a first detection resistor R1 and a second detection resistor R2. CC1 is connected to the first detection resistor R1, and CC2 is connected to the second detection resistor R2. That is, CC1 can be led out from the second end of the USB receptacle 100 through the first detection resistor R1. CC2 can be led out from the second end of the USB receptacle 100 through the second detection resistor R2.

[0050] In some embodiments, the resistance of the first detection resistor R1 is 5.1K ohms.

[0051] In some embodiments, the resistance of the second detection resistor R2 is 5.1K ohms.

[0052] In this embodiment, the detection resistor to which the CC pin must be connected is set in the USB socket 100. Compared with the electronic product provided with the USB socket 100, the circuit board 200 of the electronic product does not need to be provided with a detection resistor again. This not only reduces the requirements for the stacking structure of the circuit board 200, but also reduces the manufacturing process of the circuit board 200. Furthermore, the circuit board 200 can be more miniaturized under the premise of reducing the need for the detection resistor.

[0053] See Figure 5 , Figure 5 This is a schematic diagram of another embodiment of the electronic atomization device provided by the present application. The electronic atomization device 300 includes: a USB female socket 100 and a circuit board 200. The USB is TYPE-C.

[0054] The USB receptacle 100 includes a housing and a pin module. The pin module is disposed within the housing and includes a CC pin, a sense resistor, and a ground pin. The CC pin is connected to the ground pin via the sense resistor. The circuit board 200 is coupled to the CC pin via the ground pin. The pin module may also include a VBUS pin and a GND pin.

[0055] like Figure 5 As shown, the second end of the pin module does not actually need to expose the CC pin. Because the first detection resistor R1 and the second detection resistor R2 need to be grounded, after the CC pin is connected to the detection resistor (for example, CC1 is connected to resistor R1, and CC2 is connected to resistor R2), the first detection resistor R1 and the second detection resistor R2 are connected to the ground pin. When the USB socket 100 is subsequently set to correspond to the circuit board 200 of the electronic product, the detection resistor can be grounded through the ground pin, eliminating the need to set up additional layout circuits corresponding to the resistor grounding on the circuit board 200 of the electronic product.

[0056] Furthermore, the pin module of the USB female connector 100 only has two VBUS pins and two ground pins as output pins. That is, the USB female connector 100 is a 4-pin type, and CC1 and CC2 are connected to the ground pins through corresponding resistors inside the USB female connector 100.

[0057] In this embodiment, the electronic atomization device 300 uses the USB socket 100 mentioned in any of the above embodiments. A detection resistor to which the CC pin must be connected is provided in the USB socket 100. Compared with the electronic product provided with the USB socket 100, the circuit board 200 of the electronic product does not need to be provided with a detection resistor again. This not only reduces the requirements for the stacking structure of the circuit board 200, but also reduces the manufacturing and processing steps of the circuit board 200. Furthermore, the circuit board 200 can be more miniaturized while reducing the setting of the detection resistor.

[0058] In some embodiments, the circuit board 200 is the mainboard of the electronic atomization device 300, that is, an airflow sensor and / or a control chip are provided on the circuit board 200. That is, when the circuit board 200 is the mainboard of the electronic atomization device 300, a detection resistor to which the CC pin must be connected is provided in the USB socket 100, and a detection resistor does not need to be provided on the mainboard of the electronic atomization device 300. This not only reduces the requirements for the stacking structure of the mainboard of the electronic atomization device 300, but also reduces the manufacturing and processing steps of the mainboard of the electronic atomization device 300. Furthermore, the mainboard of the electronic atomization device 300 can be more miniaturized while reducing the need for setting detection resistors.

[0059] The CC1 and CC2 mentioned above are used to identify the insertion direction of the connector and different insertion devices. CC1 and CC2 have the following functions:

[0060] First, tell the device what specific functions are in the cable.

[0061] Second, there is a fault-tolerant mechanism for the communication protocol to ensure that the device and the cable end are correctly connected, ensuring accurate and stable data transmission.

[0062] Third, the detection resistors connected through CC1 and CC2 allow the power adapter to adjust the output current to meet the charging needs of the device.

[0063] Fourth, some TYPE-C devices support fast charging function. By communicating with the charging adapter, the maximum charging current can be adjusted to a higher value to achieve fast charging effect.

[0064] To summarize, the USB socket 100 and the electronic atomization device 300 of the present application set the detection resistor to which the CC pin must be connected in the USB socket 100. Compared with the electronic product equipped with the USB socket 100, the circuit board 200 of the electronic product does not need to be equipped with a detection resistor again. This not only reduces the requirements for the stacking structure of the circuit board 200, but also reduces the manufacturing and processing steps of the circuit board 200. Furthermore, the circuit board 200 can be more miniaturized while reducing the setting of the detection resistor.
