DETAILED DESCRIPTION

[0051] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims. It should also be understood that the term "and / or" as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0052] At present, when an electronic device is in use, an electronic device accessory may be inserted into the interface to realize the corresponding function. For example, the interface of the electronic device can be connected to an external device such as a computer or a tablet computer to realize the data transmission function between the external device and the electronic device. The interface of the electronic device can also be connected to an electronic device accessory such as a charging device and a mobile power supply to realize the charging function of the electronic device accessory to the electronic device. The interface of the electronic device can also be connected to an electronic device accessory such as an adapter and a headset to realize the audio transmission function between the electronic device accessory and the electronic device. When the interface is connected to the electronic device accessory, it can be inserted either forward or reverse, and the electronic device needs to detect whether the electronic device accessory is inserted through the detection terminal of the interface. The tongue is the core component of the interface, and a plurality of functional terminals are arranged on the surface. When the electronic device accessory or the external device is connected to the interface of the electronic device, the electronic device accessory or the external device transmits data with the electronic device through the functional terminal and charges the electronic device. The functional terminal may include, for example, a ground terminal GND, a power supply terminal VBUS, and a configuration channel terminal CC. Among them, the electronic device detects whether an electronic device accessory or an external device is inserted through the configuration channel terminal CC. When the electronic device accessory and the external device are not inserted, the voltage of the configuration channel terminal CC is a fixed voltage, which is used to indicate the "no connection" state of the electronic device accessory and the external device. When an electronic device accessory or external device is plugged in, the voltage of the configuration channel terminal CC will change, which is used to indicate different types of electronic device accessories or external devices, such as charging devices, headphones, computers, etc. Since the configuration channel terminal CC remains charged when electronic device accessories and external devices are not plugged in, when liquid enters the interface of the electronic device, the functional terminal is prone to corrosion and cause a short circuit problem.

[0053] In order to solve the problem of interface corrosion, in the related art, an interface structure is provided, in which a ground terminal GND is used as a detection terminal CID instead of a configuration channel terminal CC for insertion detection of electronic device accessories and external devices. Since there is no need to configure the channel terminal CC for insertion detection of electronic device accessories and external devices, the configuration channel terminal CC is no longer kept in a charged state, and corrosion is not easy to occur even if liquid enters the interface. By occupying a ground terminal GND in the tongue as a detection terminal CID, not only the problem of interface corrosion is solved, but also whether an electronic device accessory or external device is inserted can be detected. However, due to the reduction in the number of ground terminals GND, when the charging device is inserted into the interface to charge the electronic device, the charging current flowing through each ground terminal GND will increase under the same input current, and the temperature rise of the interface will increase. When the temperature rise of the interface is greater than the temperature rise limit, the electronic device will automatically reduce the charging current or stop charging. This is because excessive temperature rise may cause risks such as melting of the interface, resulting in damage to the electronic device. Therefore, the charging device cannot charge the electronic device through the interface with a large current, and the charging power of the electronic device is limited.

[0054] Based on this, the present disclosure provides an interface, wherein the tongue of the interface includes a plurality of preset positions for setting functional terminals, and at least one preset position is provided with a ground terminal and a detection terminal insulated from each other. Since the detection terminal does not replace the ground terminal at the preset position, the number of ground terminals does not decrease. When a charging device is inserted into the interface to charge the electronic device, the charging current flowing through each ground terminal will decrease under the same input current, thereby reducing the temperature rise generated by charging, thereby increasing the charging power of the electronic device. At the same time, since the detection terminal can detect whether an electronic device accessory is inserted into the interface, the possibility of corrosion of the functional terminal on the tongue is reduced, thereby improving the reliability of the interface structure. Moreover, since the ground terminal and the detection terminal are insulated from each other, the detection terminal is prevented from contacting the ground terminal to interfere with the function of the electronic device, thereby further improving the reliability of the interface structure.

[0055] An exemplary embodiment of the present disclosure provides an interface structure, such as Figure 1 As shown, the interface structure includes an interface 10, the interface 10 includes a tongue 11, the tongue 11 includes a plurality of preset positions P for setting functional terminals, at least one preset position P is provided with a ground terminal GND and a detection terminal CID insulated from each other.

[0056] In this embodiment, the interface structure includes an interface, and the tongue of the interface includes a plurality of preset positions for setting functional terminals, and at least one preset position is provided with a mutually insulated ground terminal and a detection terminal. By providing mutually insulated ground terminals and detection terminals at at least one preset position, it is avoided that the number of ground terminals on the tongue is reduced due to the detection terminal occupying the preset position. Since the number of ground terminals on the tongue remains unchanged, when the charging device is inserted into the interface to charge the electronic device, the temperature rise generated by charging is reduced, thereby increasing the charging power of the electronic device. At the same time, since the detection terminal can detect whether the electronic device accessory is inserted into the interface, the possibility of corrosion of the functional terminal on the tongue is reduced, thereby improving the reliability of the interface structure. Moreover, since the ground terminal and the detection terminal are insulated from each other, it is avoided that the detection terminal contacts the ground terminal and interferes with the function of the electronic device, thereby further improving the reliability of the interface structure.

[0057] Exemplarily, the interface 10 may include an inner shell, an outer shell, etc. in addition to the tongue 11 .

[0058] In one embodiment, at the same preset position P, the ground terminal GND and the detection terminal CID are arranged at intervals.

[0059] In this embodiment, the ground terminal and the detection terminal are spaced apart and insulated from each other by air, thereby improving the reliability of the interface structure. At the same time, since the ground terminal and the detection terminal can be insulated from each other without adding an insulating structure, the cost and complexity of the interface structure are reduced.

[0060] In one embodiment, if Figure 2 As shown, at the same preset position P, an insulating portion 20 is provided between the ground terminal GND and the detection terminal CID.

[0061] In this embodiment, since the insulating part has strong insulating performance, the ground terminal and the detection terminal can be reliably insulated, thereby improving the reliability of the interface structure.

[0062] Exemplarily, the insulating part 20 may be made of one or more insulating materials such as insulating plate, plastic film, rubber, etc.

[0063] Exemplarily, the insulating portion 20 , the ground terminal GND and the detection terminal CID may be integrally mounted on the tongue piece 11 , or may be separately mounted on the tongue piece 11 .

[0064] In one embodiment, if Figure 3 As shown, the projection area of ​​the detection terminal CID on the tongue piece 11 is smaller than the projection area of ​​the ground terminal GND on the tongue piece 11 .

[0065] In this embodiment, since the area of ​​the grounding terminal is larger, when the charging device is inserted into the interface to charge the electronic device, the temperature rise generated under the same charging current is lower. By making the projected area of ​​the grounding terminal larger than the projected area of ​​the detection terminal, the temperature rise generated by charging is reduced so that the charging device can charge the electronic device with a larger current, thereby improving the charging power of the electronic device.

[0066] Exemplarily, the projected shape of the detection terminal CID may be a rectangle, a square, a trapezoid, etc. The projected shape of the ground terminal GND may be a rectangle, a square, a trapezoid, etc.

[0067] In one embodiment, at least one row of preset positions P is provided on the tongue 11, and multiple preset positions P in the same row are arranged at intervals along the first direction. At the same preset position P, the ground terminal GND and the detection terminal CID are arranged along the second direction, and the second direction is arranged at an angle to the first direction.

[0068] In this embodiment, by arranging multiple preset positions in the same row at intervals along the first direction, the positions of the functional terminals in the interface remain unchanged, thereby improving the versatility of the interface structure. By making the arrangement direction of the ground terminal and the detection terminal at an angle to the arrangement direction of the preset positions, corresponding adjustments can be made according to the different functions that the interface needs to implement, thereby improving the reliability of the interface structure.

[0069] Exemplarily, the angle between the second direction and the first direction may be 30 degrees, 45 degrees, 60 degrees, 90 degrees, 125 degrees, 145 degrees, etc.

[0070] In one embodiment, at the same preset position P, the distance between the ground terminal GND and the free end of the tongue piece 11 is smaller than the distance between the detection terminal CID and the free end of the tongue piece 11 .

[0071] In this embodiment, since the distance between the ground terminal GND and the free end of the tongue 11 is greater than the distance between the detection terminal CID and the free end of the tongue 11, during the process of inserting an electronic device accessory or an external device into the interface, the electronic device accessory or the external device will first be connected to the detection terminal and then to the ground terminal. Then, in the case where the electronic device accessory or the external device is not fully inserted into the interface, the detection terminal will detect that the electronic device accessory or the external device is inserted into the interface, which may easily cause the electronic device to malfunction. Since the distance between the ground terminal GND and the free end of the tongue 11 is less than the distance between the detection terminal CID and the free end of the tongue 11, during the process of inserting an electronic device accessory or an external device into the interface, the electronic device accessory or the external device will first be connected to the ground terminal and then to the detection terminal. Since the detection terminal does not detect the insertion of the electronic device accessory or the external device when the electronic device accessory or the external device is not fully inserted into the interface, the possibility of malfunction of the electronic device is reduced, thereby improving the reliability of the interface structure.

[0072] In one embodiment, if Figure 4 As shown, at least one row of preset positions P is provided on the tongue 11, and multiple preset positions P in the same row are arranged at intervals along the first direction. At the same preset position P, the ground terminal GND and the detection terminal CID are arranged along the first direction.

[0073] In this embodiment, by arranging multiple preset positions in the same row at intervals along the first direction, the positions of the functional terminals in the interface remain unchanged, thereby improving the versatility of the interface structure. Since the grounding terminal and the detection terminal are arranged along the first direction, the electronic device accessory or external device is connected to the grounding terminal and the detection terminal at the same time during the insertion process, and the electronic device can detect the insertion of the electronic device accessory or external device to improve the reliability of the interface structure.

[0074] In one embodiment, if Figure 5 As shown, the tongue piece 11 includes a first surface 111 and a second surface 112 which are separated from each other. A row of preset positions P are arranged on the first surface 111 and the second surface 112. The preset positions P for setting the ground terminal GND and the detection terminal CID are selected from one or any combination of the following preset positions P:

[0075] A preset position P at a first end of a row of preset positions P on the first surface 111 .

[0076] A preset position P at a second end of a row of preset positions P on the first surface 111 .

[0077] A preset position P at a first end of a row of preset positions P on the second surface 112 .

[0078] A preset position P at a second end of a row of preset positions P on the second surface 112 .

[0079] In the present embodiment, since ground terminals are provided at the preset positions of the first end of the first surface of the tongue, the second end of the first surface, the first end of the second surface and the second end of the second surface, by selectively replacing the ground terminals in some or all of the preset positions with ground terminals and detection terminals, the charging power of the electronic device is improved on the basis of realizing insertion detection of electronic device accessories and external devices.

[0080] Exemplarily, the ground terminal GND in one preset position P can be replaced by the ground terminal GND and the detection terminal CID, the ground terminals GND in two preset positions P can be replaced by the ground terminal GND and the detection terminal CID, the ground terminals GND in three preset positions P can be replaced by the ground terminal GND and the detection terminal CID, and the ground terminals GND in four preset positions P can be replaced by the ground terminal GND and the detection terminal CID.

[0081] It can be understood that when the ground terminals GND in the four preset positions P are replaced with the ground terminal GND and the detection terminal CID, for electronic device accessories and external devices that are only provided with 1, 2 or 3 ground terminals GND, the problem of being unable to be identified due to the ground terminal GND of the electronic device accessories and external devices not being connected to the detection terminal CID of the interface 10 can be avoided.

[0082] In one embodiment, the interface 10 is a Type-C interface.

[0083] In this embodiment, since the Type-C interface can be inserted forward and backward, insertion detection of electronic device accessories and external devices is required. By setting mutually insulated ground terminals and detection terminals at at least one preset position, it is avoided that the detection terminal occupies the preset position, resulting in a reduction in the number of ground terminals on the tongue. Since the number of ground terminals remains unchanged, the restriction on charging power is reduced while avoiding interface corrosion, thereby increasing the charging power of the electronic device. At the same time, since the Type-C interface is a powerful and widely used interface, most electronic devices use the Type-C interface for charging and data transmission, thereby improving the versatility of the interface structure.

[0084] It can be understood that, in addition to the Type-C interface, interface 10 can also be a Type-A interface, a Type-B interface, a VGA interface, an HDMI interface, a DP interface, a DVI interface, a USB interface, an RJ45 interface, an MHL interface and a Micro USB interface.

[0085] In one embodiment, the interface 10 is a female socket.

[0086] In this embodiment, since the interface of the electronic device is a female socket, the charging power of the electronic device and the versatility of the interface structure are improved by arranging a ground terminal and a detection terminal at at least one preset position of the tongue.

[0087] For example, Figure 6 As shown, when the male plug of an electronic device accessory or an external device is inserted into the female socket of the electronic device, the functional terminal of the male plug will be connected to the functional terminal corresponding to the female socket. Among them, the ground terminal GND of the male plug is connected to the ground terminal GND and the detection terminal CID of the female socket, the first functional terminal A1 of the male plug is connected to the first functional terminal A1 of the female socket, and the second functional terminal of the male plug is connected to the second functional terminal of the female socket. Since the ground terminal GND of the male plug can be connected to the ground terminal GND and the detection terminal CID of the female socket, the charging current of the charging device can flow through the ground terminal GND of the female socket and the electronic device can detect whether the electronic device accessory or external device is inserted through the detection terminal CID, thereby improving the charging power of the electronic device and reducing the possibility of corrosion of the interface.

[0088] In one embodiment, the interface 10 is a male connector.

[0089] In this embodiment, since the interface between the electronic device accessories and the external device is a male plug, by setting a ground terminal and a detection terminal at at least one preset position of the tongue, the charging power of the electronic device accessories and the external device and the versatility of the interface structure are improved.

[0090] In one embodiment, if Figure 7 As shown, the interface structure further includes a detection circuit 30. The detection circuit 30 is connected to the detection terminal CID. The detection circuit 30 is used to detect whether an electronic device accessory or an external device is inserted through the detection terminal CID.

[0091] In this embodiment, since the levels of the detection terminals are different when the electronic device accessory and the external device are not inserted into the interface and when they are inserted into the interface, the level of the detection terminal is detected by the detection circuit, so as to detect whether the electronic device accessory or the external device is inserted into the interface to improve the reliability of the interface structure.

[0092] Exemplarily, when the electronic device accessory and the external device are not plugged into the interface 10, the level of the detection terminal CID is a floating level. When the electronic device accessory or the external device is plugged into the interface 10, the level of the detection terminal CID is a low level.

[0093] In one embodiment, if Figure 8 As shown, the detection circuit 30 includes a processing unit 31. The processing unit 31 is connected to the detection terminal CID.

[0094] In this embodiment, the processing unit is connected to the detection terminal to directly transmit the level of the detection terminal to the processing unit. The processing unit determines whether an electronic device accessory or external device is inserted based on the level of the detection terminal, thereby improving the reliability of the interface structure.

[0095] In one embodiment, there are multiple detection terminals CID, and the processing unit 31 is connected to each detection terminal CID.

[0096] In this embodiment, when there are multiple detection terminals, the processing unit is connected to each detection terminal, so that the processing unit can judge whether there is an electronic device accessory or an external device plugged into the interface according to the level of each detection terminal. Since there are multiple detection terminals, the problem of an electronic device accessory or an external device being unable to be identified due to having only one ground terminal is avoided, thereby improving the reliability of the interface structure.

[0097] Exemplarily, when the level of one detection terminal CID or multiple detection terminals CID changes, the processing unit 31 determines that an electronic device accessory or an external device is plugged into the interface 10 .

[0098] In one embodiment, if Fig. 9 As shown, each detection terminal CID is connected to an input terminal of the processing unit 31 respectively.

[0099] In this embodiment, by connecting each detection terminal to an input terminal of the processing unit respectively, the processing unit can determine whether an electronic device accessory or an external device is inserted through the voltage level of each input terminal, thereby reducing the complexity of the detection circuit detection and reducing the complexity of the detection circuit structure.

[0100] In one embodiment, if Fig.10 As shown, the detection circuit 30 also includes a switch circuit 32 and a control circuit 33. Each first end of the switch circuit 32 is connected to a detection terminal CID, and each second end of the switch circuit 32 is connected to and connected to the input end of the processing unit 31. The control circuit 33 is connected to the control end of the switch circuit 32, and the control circuit 33 is used to make each first end and the corresponding second end of the switch circuit 32 cyclically conductive.

[0101] In this embodiment, the control circuit controls each first end and the corresponding second end of the switch circuit to be cyclically connected, so that each detection terminal and the processing unit are cyclically connected, thereby reducing the occupancy of the input terminal of the processing unit to improve the functionality of the interface structure.

[0102] In one embodiment, if Fig.11 As shown, the switch circuit 32 includes a plurality of switch units, a first end of each switch unit is connected to a detection terminal CID, and a second end of each switch unit is connected to an input end of the processing unit 31 .

[0103] In this embodiment, the detection terminal is connected to the processing unit through each switch unit, so that the control circuit controls the conduction and disconnection of each switch unit to control the cyclic conduction of each detection terminal and the processing unit, thereby reducing the complexity of the detection circuit control.

[0104] Exemplarily, the switch unit may include a transistor.

[0105] Exemplarily, taking the number of switch units as 4 as an example, the control circuit 33 controls the first ends and the corresponding second ends of the switch circuit 32 to be cyclically turned on to explain. The control circuit controls the first switch unit to be turned on within a certain period of time, and controls the other switch units to be turned off. Then the second switch unit is controlled to be turned on, and the other switch units are controlled to be turned off. Then the third switch unit is controlled to be turned on, and the other switch units are controlled to be turned off. Then the fourth switch unit is controlled to be turned on, and the other switch units are controlled to be turned off. Then the first switch unit is controlled to be turned on, and the other switch units are controlled to be turned off, and the cycle is repeated in sequence. That is, only one switch unit is turned on each time.

[0106] In one embodiment, the output terminal of the processing unit 31 is connected to the enable terminal of the control circuit 33, and the processing unit 31 is used to enable or stop the control circuit 33.

[0107] In this embodiment, since the electronic device may not need to immediately detect whether there is an electronic device accessory or an external device plugged into the interface when it is powered on, the processing unit can stop the control circuit from running to reduce the power consumption of the control circuit. The electronic device needs to detect whether there is an electronic device accessory or an external device plugged into the interface after being powered on for a period of time, and the processing unit can control the operation of the control circuit to perform the detection. By controlling the operating state of the control circuit by the processing unit, on the one hand, the power consumption of the electronic device can be reduced, and on the other hand, the electronic device accessories and external devices can be detected while reducing the possibility of corrosion of the interface.

[0108] An exemplary embodiment of the present disclosure provides an interface structure, such as Fig.12As shown, the interface structure includes an interface 10 and a detection circuit 30.
