It should be noted that the method for identifying corrosion of the connector provided in the embodiment of the present application can be operated with the first device or the second device, and the implementation principles of the first device and the second device are similar. Therefore, in the following embodiments, the operation of the first device is mainly used as an example for description.

Example 1

FIG. 3 is a flowchart of a method for identifying corrosion of a connector in one embodiment. The corrosion identification method of the connector in this embodiment is described by taking the operation on the first device in FIG. 1 as an example. As shown in Figure 3, the corrosion identification method of the connector includes the following steps:

S301: Acquire a first parameter of the connector of the first device; the first parameter is the parameter of the connector of the first device collected when the first device is not connected to the second device.

Wherein, the connector of the first device is a connector of the first device, for example, the connector of the first device may be a POGO PIN, a spring pressing piece, a terminal, etc. on the first device. The first parameter is a parameter of the connector of the first device collected when the connector of the first device is not in contact with the connector of the second device, and the first parameter may be the voltage, current, impedance on the connector of the first device and other parameters.

In this embodiment, before the first device is not connected to the second device, the first device collects current, voltage, impedance, etc. on the connector of the first device as the first parameter. Various sensors may be provided inside the first device, for example, a current sensor, a voltage sensor, etc., for collecting the first parameter.

Taking the first device as the charging box and the second device as the earphone as an example, before the earphone is not put into the charging box, collect at least one of the voltage, current and impedance on the POGO PIN of the charging box as the first parameter, or, when When the first device is an earphone and the second device can be an earphone box, before the earphone is not put into the charging box, at least one of the voltage, current and impedance on the POGO PIN of the earphone is collected as the first parameter. Not limited to this.

S302: Determine the corrosion state of the connector of the first device according to the first parameter.

The corrosion state is used to indicate whether the connector is corroded, and the corrosion state of the connector of the first device indicates whether the connector of the first device is corroded.

In this embodiment, when the first device is not connected to the second device, the first parameter of the connector of the first device is collected, and the corrosion state of the connector of the first device can be determined according to the first parameter. Under normal circumstances, when the connector is not corroded, the voltage, current, impedance, etc. on the connector are all fixed values. Once the connector is corroded, the voltage on the connector may decrease, and the leakage may cause excessive current and impedance. Therefore, the collected first parameter can be compared with the parameter value when the connector is not corroded, so as to judge the corrosion state of the connector of the first device.

For example, when the connector of a common earphone charging box is not corroded, the voltage on the connector of the charging box is 5V. When the connector is corroded, it is equivalent to connecting a resistance in parallel with the resistance of the connector, and the resistance of the connector becomes smaller. , its voltage will also decrease. You can collect the voltage value on the POGO PIN of the charging box when the earphone is not placed in the charging box. If the voltage value on the POGO PIN is less than 5V, it is determined that the connector of the charging box is corroded. Or, if the voltage value on the POGO PIN is within a certain voltage range, it can be determined that the connector of the charging box is not corroded. For example, when the headset is not placed in the charging box, the voltage value on the POGO PIN of the charging box In the range of 4.8V-5V, it is determined that the POGO PIN is not corroded. If the voltage value on the POGOPIN of the charging box is less than 4.8V, it is determined that the POGO PIN is corroded. For another example, when the connector of the common earphone charging box is not corroded, the current on the connector of the charging box is 2A. If the connector is corroded, leakage may occur, resulting in an increase in the current on the connector, which can be collected. When the headset is not placed in the charging box, the current on the POGO PIN of the charging box, if the current is greater than 2A, it is determined that the connector of the charging box is corroded, or, if the current on the POGO PIN is within a certain current range, It can be determined that the connector of the charging box is not corroded. For example, when the headset is not placed in the charging box, the current on the POGO PIN of the charging box is in the range of 1.9A-2.1A, then it is determined that the POGO PIN is not corroded. , if the current on the POGO PIN of the charging box is greater than 2.1A, it is determined that the POGO PIN is corroded. When the first parameter is the collected voltage and current on the POGO PIN of the earphone, the implementation principle thereof is similar to that of the earphone box, which will not be repeated here.

It should be noted that when determining the corrosion state of the connector of the first device according to the first parameter, an appropriate first parameter and method may be selected according to the actual situation to determine the corrosion state of the connector of the first device. is not restricted.

It should be noted that, in the above-mentioned embodiments, the first device is an earphone box and the second device is an earphone as an example to illustrate the method for identifying corrosion of the connector. The first device is an earphone and the second device is an earphone. It will not be repeated here.

In the method for identifying corrosion of a connector provided by the embodiment of the present application, the first parameter of the connector of the first device collected when the first device is not connected to the second device is acquired, and the first parameter of the connector of the first device is determined according to the first parameter. Corrosion state, through the parameters of the connector of the first device collected when the first device and the second device are not connected, to determine whether the connector of the first device is corroded, and the corrosion of the connector of the first device can be identified in time, Reduce the influence of poor contact caused by corrosion of the connector.

Embodiment 2

On the basis of the embodiment shown in FIG. 3 , the second parameter of the connector of the first device collected when the first device is connected to the second device can be further obtained, and the second parameter can be determined according to the first parameter and the second parameter. Corrosion state of the connector of the device. As shown in FIG. 4 , the method for identifying corrosion of the connector may further include the following steps:

S401. Acquire a second parameter of the connector of the first device; the second parameter is a parameter collected when the first device and the second device are connected through the connector.

The second parameter is a parameter of the connector of the first device collected when the first device and the second device are connected through the connector. For example, the second parameter may be parameters such as voltage, current, and resistance collected on the connector of the first device when the first device and the second device are connected through the connector.

Taking the first device as the charging box and the second device as the earphone as an example, after the earphone is placed in the charging box, collect at least one of the voltage, current and impedance on the POGO PIN of the charging box as the second parameter, or when the first When the first device is an earphone and the second device can be an earphone box, after the earphone is put into the charging box, at least one of the voltage, current and impedance on the POGO PIN of the earphone is collected as the second parameter. This is the limit.

S402. Determine the corrosion state of the connector of the second device according to the first parameter and the second parameter.

In this embodiment, the value of the first parameter and the value of the second parameter may be compared in magnitude to determine the corrosion state of the connector of the second device. For example, if the first parameter includes collecting the voltage A on the connector of the first device when the first device is not connected to the second device, and the second parameter includes collecting the voltage A when the first device and the second device are connected through the connector The voltage B on the connector of the device may decrease the voltage on the connector due to the corrosion of the connector. Therefore, if the voltage B is less than the voltage A, it is determined that the connector of the second device is corroded. If the voltage B is equal to voltage A, it is determined that the connector of the second device is not corroded. Alternatively, the first parameter includes collecting the current C on the connector of the first device when the first device is not connected to the second device, and the second parameter includes collecting the first device when the first device and the second device are connected through the connector The current D on the connector, because the connector is corroded, the leakage of the connector may cause the phenomenon of excessive current. Therefore, if the current C is less than the current D, it is determined that the connector of the second device is corroded. If the current C is equal to Current D, it is determined that the connector of the second device is not corroded.

Alternatively, the corrosion state of the connector of the second device may also be determined by the degree of change between the value of the first parameter and the value of the second parameter. If the first parameter includes collecting the voltage A on the connector of the first device when the first device is not connected to the second device, and the second parameter includes collecting the voltage A of the first device when the first device and the second device are connected through the connector The voltage B on the connector may decrease due to the corrosion of the connector. If the difference between the voltage B and the voltage A is less than the preset voltage difference, that is, the first device and the second device Before and after the connection, the voltage change on the connector of the first device is small, it is determined that the second connector is not corroded, if the difference between the voltage B and the voltage A is greater than or equal to the preset voltage difference, that is, the first Before and after the device is connected to the second device, if the voltage on the connector of the first device changes greatly, it is determined that the second connector is corroded. Alternatively, the first parameter includes collecting the current C on the connector of the first device when the first device is not connected to the second device, and the second parameter includes collecting the first device when the first device and the second device are connected through the connector. The current D on the connector of the device, because the connector is corroded, the leakage of the connector may cause the phenomenon of excessive current. Therefore, if the difference between the current C and the current D is greater than the preset current difference, the second device is determined. The connector of the second device is corroded, and if the difference between the current C and the current D is less than or equal to the preset current difference, it is determined that the connector of the second device is not corroded.

In the method for identifying corrosion of a connector provided in this embodiment of the present application, the second parameter of the connector of the first device is obtained, and the corrosion state of the connector of the second device is determined according to the first parameter and the second parameter, since the first parameter It is the parameter of the connector of the first device collected when the first device is not connected to the second device, and the second parameter is the parameter collected when the first device and the second device are connected through the connector. The parameters of the connector of the first device before and after the device is connected can quickly determine the corrosion condition of the connector of the second device, and reduce the influence of poor contact caused by the corrosion of the connector.

Embodiment 3

On the basis of the embodiment shown in FIG. 3 , the second parameter of the connector of the first device collected when the first device is connected to the second device can be further obtained, based on the corrosion state of the connector of the first device and the The second parameter determines the corrosion state of the connector of the second device. As shown in FIG. 5 , the method for identifying corrosion of the connector may further include the following steps:

S501. Acquire a second parameter of the connector of the first device; the second parameter is a parameter collected when the first device and the second device are connected through the connector.

For the implementation principle of this embodiment, reference may be made to step S401 in the second embodiment, which will not be repeated here.

S502. Determine the corrosion state of the connector of the second device according to the corrosion state of the connector of the first device and the second parameter.

The corrosion state of the connector of the first device is that the connector of the first device is corroded or the connector of the first device is not corroded, and the corrosion state of the connector of the second device indicates whether the connector of the second device is corroded .

In this embodiment, after the corrosion state of the connector of the first device is determined, the corrosion state of the connector of the second device may be determined based on the corrosion state of the connector of the first device and the second parameter. For example, when the corrosion state of the connector of the first device is determined, the value of the second parameter can be compared with a preset parameter threshold to determine the corrosion state of the connector of the second device, or the value of the first parameter and the The value of the second parameter is compared to determine the corrosion state of the connector of the second device, and the corrosion state of the connector of the second device may also be determined by collecting some parameters of the second device during the charging process.

Taking the charging box and the earphone as an example, when it is determined that the connector of the charging box is not corroded, if the connector of the earphone is not corroded, the voltage change on the connector of the charging box before and after the earphone is placed in the charging box is very small. If the connector of the earphone is corroded, the voltage change on the connector of the charging box before and after the earphone is placed in the charging box will be relatively large. You can collect the voltage value a of the connector of the charging box when the earphones are placed in the charging box, and compare the voltage value a with the voltage value b of the connector of the charging box when the earphones are not placed in the charging box. If the difference between the voltage value b and the voltage value b is less than a certain threshold, it is determined that the connector of the earphone is not corroded. If the difference between the voltage value a and the voltage value b is greater than a certain threshold value, it is determined that the connector of the earphone is corroded. Alternatively, it is also possible to directly compare the voltage value a with a preset threshold value. If the voltage value a is greater than or equal to the threshold value, it is determined that the connector of the earphone is not corroded, and if the voltage value a is smaller than the threshold value, it is determined that The connector of the headset is corroded. Similarly, when it is determined that the charging box is corroded, if the connector of the earphone is not corroded, the voltage on the connector of the charging box before and after the earphone is placed in the charging box changes very little. The voltage change on the connector of the charging box before and after it is placed in the charging box will also be relatively large. You can also use the above voltage value comparison method to determine whether the connector of the earphone is corroded. The difference is that the threshold or the range of the threshold value is different. The embodiments of the present application are not limited thereto.

Alternatively, after the corrosion state of the connector of the charging box is determined, it can be determined whether the connector of the earphone is corroded by the change of the current on the connector of the charging box before and after the earphone is placed in the charging box. For example, if the charging box The connector of the charging box is not corroded. The current of the connector of the charging box before the earphone is placed in the charging box is c, and the current of the connector of the charging box after the earphone is placed in the charging box is d. If the difference between the current c and the current d is less than the preset value If the current threshold is set, it is determined that the connector of the earphone is not corroded. If the difference between the current c and the current d is greater than or equal to the current threshold, it is determined that the connector of the earphone is corroded, and the embodiment of the present application is not limited to this.

In the method for identifying corrosion of a connector provided by the embodiment of the present application, the first parameter of the connector of the first device collected when the first device is not connected to the second device is acquired, and the first parameter of the connector of the first device is determined according to the first parameter. Corrosion state, and when the first device and the second device are connected through the connector, the second parameter of the connector of the first device is collected, and the corrosion state of the connector of the first device and the second parameter are used to determine the second device. The corrosion state of the connector can identify the corrosion state of the connector of the second device in time, and reduce the influences such as poor contact caused by the corrosion of the connector.

Embodiment 4

In the embodiment shown in FIG. 3, there are various ways to determine the corrosion state of the connector of the first device according to the first parameter. In one embodiment, the corrosion state of the connector of the first device is determined according to the first parameter, The method includes: determining the corrosion state of the connector of the first device according to the first parameter and the preset threshold.

Wherein, different first parameters correspond to different preset thresholds. For example, if the first parameter is current, the preset threshold is a preset current threshold, and if the first parameter is voltage, the preset threshold is a preset voltage threshold, If the first parameter is a resistance value, the preset threshold is a preset resistance threshold, and different preset thresholds can be determined according to actual requirements, device parameters of the first device, device parameters of the second device, etc., for example, for normal rate charging For the second device that requires fast charging, the preset threshold can be appropriately set to a smaller value, or the range of the preset threshold can be appropriately larger. For the second device that requires fast charging, the charging time is required to be higher. , the preset threshold may be appropriately set to be larger, or the range of the preset threshold may be appropriately smaller, which is not limited in this embodiment of the present application.

In this embodiment, the first device may select a corresponding preset threshold according to the type of the collected first parameter, so as to determine the corrosion state of the connector of the first device. The value of the first parameter can be compared with the preset threshold, and the corrosion state of the connector of the first device can be determined according to the magnitude relationship between the value of the first parameter and the preset threshold. For example, when the value of the first parameter is greater than the preset threshold , the connector of the first device is not corroded, and when the value of the first parameter is less than the preset threshold, the connector of the first device is corroded. By using the first parameter and the preset threshold, the corrosion state of the connector of the first device can be quickly and simply determined, so as to reduce the influence of the corrosion of the connector on the first device.

Embodiment 5

This embodiment focuses on the specific implementation process of determining the corrosion state of the connector of the first device when the first parameter is voltage. In this embodiment, the first parameter includes a first voltage, and the first voltage is the voltage on the connector of the first device collected when the first device is not connected to the second device. According to the first parameter and the preset threshold, Determining the corrosion state of the connector of the first device includes: if the first voltage is greater than or equal to a preset first voltage threshold, determining that the connector of the first device is not corroded; if the first voltage is less than the first voltage threshold, Then it is determined that the connector of the first device is corroded.

In this embodiment, some resistors may be set in the first device to collect the voltage on the connector of the first device. As shown in FIG. 6 , the first device includes a first resistor R1 and a second resistor R2, the first end of the first resistor R1 is connected to the preset voltage V1, the second end of the first resistor R1 is connected to the first end of the second resistor R2 The second end of the second resistor R2 is connected to the ground, the first end of the second resistor R1 is also connected to the charging contact OPGO PIN+ of the connector of the first device, and the second end of the second resistor is also connected to the first device. The ground contact of the connector is OPGO PIN-connected. In this embodiment, the charging contact OPGO PIN+ and the grounding contact OPGO PIN- of the connector of the first device can be connected to the processor of the first device, and the voltage V2 is collected by the processor of the first device.

The first resistor R1 and the second resistor R2 may be specially set as resistors inside the first device, or may be equivalent resistors of other functional devices in the first device, which are not limited in the embodiments of the present application.

As shown in FIG. 6 , the equivalent circuit diagram includes voltage V1, resistor R1, resistor R2, voltage V2, and voltage V3. When the earphone box charges the earphone, power is provided by voltage V3. For example, the voltage V3 can be stable 5V voltage. In order to avoid the influence of the voltage V3 or other charging voltages on the measured voltage on the OPGO PIN, generally after the earphone box is not charged to the earphone or the charging process is disconnected, the voltage V2 can be collected by the processor as the above-mentioned first voltage, the first voltage Equivalent to V2=V1*R2/(R1+R2), when there is no corrosion between POGO PIN+ and POGO PIN- of the charging box, the resistance R2 is very large, and the voltage of V2 is relatively high.

In this embodiment, the circuit when the connector of the charging box is corroded is equivalent to the circuit diagram shown in Figure 7. When there is corrosion between the POGO PIN+ and POGO PIN- of the charging box, it is equivalent to connecting the resistor R2 in parallel. A resistor, therefore, the equivalent circuit diagram shown in Figure 7 includes voltage V1, resistor R1, resistor R2, resistor R3, and voltage V2. When there is corrosion between POGO PIN+ and POGO PIN- of the charging box, similar to the resistance A resistor R3 is connected in parallel with R2, the impedance between POGO PIN+ and POGOPIN- becomes smaller, V2=V1*(R2//R3)/(R1+R2//R3), so the voltage of V2 becomes smaller.

In this embodiment, referring to the circuit principles shown in FIG. 6 and FIG. 7 , the first voltage threshold can be preset to collect the first voltage V2 across R2 when the earphone is not placed in the charging box. When the first voltage V2 is greater than or equal to When the first voltage threshold is set, it is determined that the connector of the charging box is not corroded, and when the second voltage V2 is less than the first voltage threshold, it is determined that the connector of the charging box is corroded. For example, when the connector of the earphone box is not corroded, the voltage on the connector is 5V, and the first voltage threshold may be set to 4.9V, 4.85V, 4.8, etc., which is not limited in the embodiments of the present application. The first voltage threshold can be obtained by collecting the voltages on the connectors of a plurality of first devices in uncorroded and corroded states, respectively, and obtained through multiple tests, and can also be calculated according to the principle of equivalent circuit obtained, which is not limited in the examples of the present application.

In the method for corroding a connector provided by the embodiment of the present application, when the first device is not connected to the second device, the collected first voltage on the connector of the first device, if the first voltage is greater than or equal to the preset first voltage voltage threshold, it is determined that the connector of the first device is not corroded; if the first voltage is less than the first voltage threshold, it is determined that the connector of the first device is corroded, by comparing the first voltage with the preset first voltage threshold size, the corrosion state of the connector of the first device can be quickly and accurately determined.

In this embodiment, when the first device is connected to the second device, the collected second voltage on the connector of the first device can be determined according to the second voltage and the The preset second voltage threshold determines the corrosion state of the connector of the second device, or the voltage difference between the first voltage and the second voltage is calculated, and the connector of the second device is determined according to the magnitude of the voltage difference corrosion state. In the case that the connector of the first device is corroded, the corrosion state of the connector of the second device may be determined according to the second voltage and the preset second voltage threshold, or the corrosion state of the connector of the second device may be determined according to the difference between the first voltage and the second voltage. The degree of change determines the corrosion state of the connector of the second device.

The specific implementation of this solution will be described below by taking as an example that the connector of the first device is not corroded and the corrosion state of the connector of the second device is determined according to the second voltage and the preset second voltage threshold. In this embodiment, taking the second device as an earphone as an example, to identify whether the POGO PIN of the earphone is corroded, the principle is that the POGO PIN of the earphone can be equivalent to a resistor R4, when the earphone is put into the charging box , which is equivalent to connecting a resistor R4 in parallel on the POGO PIN+ and POGO PIN- of the charging box. The schematic diagram is shown in Figure 8. The earphone is placed in the charging box with the POGO PIN uncorroded. At this time, V2=V1*(R2 //R4)/(R1+R2//R4), where R4 represents the resistance value at both ends of the POGO PIN of the headset. When the POGO PIN of the headset is not corroded, the resistance value of R4 is relatively large, and V2 is relatively large.

In this embodiment, when the POGO PIN of the earphone is corroded, as shown in FIG. 9 , both ends of the POGO PIN of the earphone are equivalent to a resistor connected in parallel, that is, a resistor R5 is connected in parallel to both ends of R4 . When the POGO PIN corroded charging box is put into the POGO PIN corroded charging box, its equivalent circuit diagram is shown in Figure 10, at this time V2=V1*(R2//R5//R4)/(R1+R2// R5//R4), since the POGO PIN of the charging box is not corroded, the V2 voltage measured on the charging box is relatively high before putting the earphones in, but the POGO PIN on the earphone end is corroded. At this time, the POGO PIN on the earphone end is equivalent to resistance R4 //R5 is relatively small, so when the headset is put in, the voltage of V2 will be much lower. From this, it can be judged that the POGO PIN of the charging box itself is not corroded, but the POGO PIN of the earphone is corroded.

Based on the above circuit principle, you can set the corresponding second voltage threshold or voltage difference based on the voltage change of the POGO PIN of the earphone box before and after the earphone is put into the POGO PIN uncorroded charging box, and put the earphone into the POGO PI uncorroded charging box. After the charging box, the second voltage and the second voltage threshold collected to the POGO PIN of the charging box determine the corrosion of the connector of the earphone, or the charging data collected before and after the earphone is put into the POGO PIN uncorroded charging box. The actual difference of the voltage of the POGO PIN of the box is compared with the preset voltage difference threshold to determine the corrosion of the connector of the earphone.

In this embodiment, determining the corrosion state of the connector of the second device according to the second voltage and the preset second voltage threshold includes: if the second voltage is greater than or equal to the second voltage threshold, determining the corrosion state of the connector of the second device The connector is not corroded; if the second voltage is less than the second voltage threshold, it is determined that the connector of the second device is corroded.

In this embodiment, the second voltage threshold may be preset, and the second voltage is compared with the second voltage threshold to determine the corrosion state of the connector of the second device. As shown in Figure 10, when the earphone is put into the charging box, the second voltage V2 on the POGO PIN of the charging box is collected. When the second voltage V2 is greater than or equal to the second voltage threshold, it means that the resistance value on the POGOPIN of the earphone is relatively large. , confirm that the POGO PIN of the headset is not corroded; when the second voltage V2 is less than the second voltage threshold, it means that the resistance value on the POGO PIN of the headset is relatively small, and it is determined that the POGO PIN of the headset is corroded.

It should be noted that the second voltage threshold may be the same as the first voltage threshold, the second voltage threshold may also be different from the first voltage threshold, and the second voltage threshold may be smaller than the first voltage threshold, for example, the second voltage threshold may be 4.85V, 4.8V, 4.75V, 4.7V, etc., the embodiments of the present application are not limited thereto. The second voltage threshold may be the case where the connector of the first device is not corroded, the connector of the second device is not corroded, and the connector of the second device is corroded, etc. The voltage on the connector of the second device is obtained through multiple measurement experiments, or it may be calculated according to the equivalent circuit, which is not limited in the embodiments of the present application.

In the connector corrosion identification method provided by the embodiment of the present application, when the first device is connected to the second device, the second voltage on the connector of the first device is collected, and if the second voltage is greater than or equal to the second voltage threshold, then determine The connector of the second device is not corroded; if the second voltage is less than the second voltage threshold, it is determined that the connector of the second device is corroded, and the second device can be simply and accurately determined by the preset second voltage threshold Whether the connector is corroded, so as to reduce the impact of connector corrosion on the second device.

Embodiment 7

The above focuses on the implementation of determining the corrosion state of the connector of the second device when the connector of the first device is not corroded. Implementation of the corroded state of the connector.

In this embodiment, the equivalent circuit when the connector of the charging box is corroded is shown in Figure 7, and as shown in Figure 11, when the POGO PIN corroded charging box is put into the POGO PIN uncorroded earphone, it is equivalent to Connect a resistor R4 in parallel with the resistors R2 and R3. At this time, V2=V1*(R2//R3//R4)/(R1+R2//R3//R4), because the charging box is corroded, so put it in Before the headset, the V2 voltage measured on the charging box is relatively low. However, the POGO PIN on the earphone end is not corroded, and the resistance R4 is still relatively large at this time, so when the earphone is put in, the voltage of V2 will not become much lower. It can be judged that when the POGO PIN of the charging box itself is corroded, the voltage V2 before and after the earphone is put into the charging box changes relatively small, and the POGO PIN of the earphone is not corroded.

In this embodiment, as shown in Figure 12, when the POGO PIN of the charging box is corroded, after putting the corroded earphones, it is equivalent to connecting a resistor R5 in parallel on the basis of the resistors R2, R3, and R4. At this time, V2 ＝V1*(R2//R3//R5//R4)/(R1+R2//R3//R5//R4), because the POGO PIN of the charging box is corroded, so before putting the earphones, test on the charging box The resulting V2 voltage is relatively low. However, the POGO PIN on the earphone end is corroded. At this time, the equivalent resistance R4//R5 of the POGO PIN on the earphone end is relatively small, so when the earphone is put in, the voltage of V2 will be much lower again. It can be judged that when the POGO PIN of the charging box itself is corroded, and the voltage V2 before and after the earphone is put into the charging box changes greatly, the POGO PIN of the earphone is corroded.

Based on the above principles of the equivalent circuit diagrams shown in FIGS. 11 and 12 , in the case that the connector of the first device is corroded, the connector of the second device can be determined according to the second voltage and the preset second voltage threshold. The corrosion state of the connector of the second device can also be determined according to the voltage difference between the first voltage and the second voltage. Further, in this embodiment, determining the corrosion state of the connector of the second device according to the voltage difference between the first voltage and the second voltage includes: if the voltage difference is less than a preset first difference threshold , it is determined that the connector of the second device is not corroded; if the voltage difference is greater than or equal to the first difference threshold, it is determined that the connector of the second device is corroded.

In this embodiment, when the connector of the first device is corroded, if the voltage difference between the first voltage and the second voltage is smaller than the preset first difference threshold, the connection of the second device is determined The device is not corroded; if the difference between the first voltage and the second voltage is greater than or equal to the first difference threshold, it is determined that the connector of the second device is corroded. That is to say, in the case where the connector of the first device is corroded, if the voltage on the connector of the first device before the first device is connected with the second device, the first device after the first device is connected with the second device If the change between the voltages on the connectors of the second device is small, it is determined that the connector of the second device is not corroded; if the voltage on the connector of the first device before the first device is connected to the second device, the After the second device is connected, the change between the voltages on the connector of the first device is large, and it is determined that the connector of the second device is corroded.

Taking the headset and the charging box as an example, the POGO PIN of the charging box is corroded, and the first difference threshold is 0.2V. If the headset is placed in the charging box, the first voltage of the POGO PIN of the charging box is 4.7V, and the headset is placed in the charging box. When in the box, the second voltage of the POGOPIN of the charging box is 4.6V, the voltage difference between the first voltage and the second voltage is 0.1V, and 0.1V is less than 0.2V, then it is determined that the POGO PIN of the headset is not corroded. If the first voltage of the POGO PIN of the charging box is 4.7V before the headset is put into the charging box, and the second voltage of the POGO PIN of the charging box is 4.4V when the headset is put into the charging box, the difference between the first voltage and the second voltage is 4.4V. If the voltage difference is 0.3V, and 0.3V is greater than 0.2V, it is determined that the POGO PIN of the headset is corroded.

In the method for identifying corrosion of a connector provided by an embodiment of the present application, in the case that the connector of the first device is corroded, the first voltage of the connector of the first device is collected when the first device is not connected to the second device, and , when the first device is connected to the second device, the second voltage of the connector of the first device, calculate the voltage difference between the first voltage and the second voltage, if the voltage difference is less than the preset first difference threshold , then it is determined that the connector of the second device is not corroded; if the voltage difference is greater than or equal to the first difference threshold, it is determined that the connector of the second device is corroded, before and after the first device is connected to the second device, the first The degree of voltage change on the connector of the device can identify the corrosion state of the connector of the second device. This method can simply and accurately identify the corrosion state of the connector of the second device and reduce the corrosion effect of the connector of the second device. The effect of the second device.

Embodiment 8

In this embodiment, the location of current collection is different, and the way to identify the corrosion state of the connector is also different. This embodiment focuses on the implementation of collection of current between the connector of the first device and the power supply or the ground terminal.

In this embodiment, on the basis of the embodiment shown in FIG. 6 , as shown in FIG. 13 , the first device further includes a first current sensor, the input end of the first current sensor is connected to the preset voltage V1 , and the first current The output end of the sensor is connected to the first end of the first resistor R1. The equivalent circuit of the charging box may include a preset voltage V1, a resistance R1 and a resistance R2, and an ammeter is set between the voltage V1 and the resistance R1 for collecting the current at the connector end of the charging box. As shown in Figure 6 and Figure 7, when the POGO PIN terminal of the charging box is corroded, it is equivalent to connecting the resistor R3 in parallel with the resistor R2, which is equivalent to the resistance of the POGO PIN terminal of the charging box becoming smaller, and the current of the POGO PIN terminal of the charging box will be reduced. Therefore, when there is no earphone in the charging box, the current is relatively small, indicating that the POGO PIN terminal in the charging box is not corroded; when the current is still relatively large, it means that the corrosion of the POGO PIN terminal in the charging box is more serious. After the earphone is put into the charging box, if the current change is relatively small, it means that the POGO PIN end of the earphone is not corroded; but when the current change is relatively large, it means that the corrosion of the POGO PIN end of the earphone is more serious.

Taking the above Figure 13 as an example, when the earphone is not placed in the charging box, the current e between the voltage V1 of the charging box and the resistance R1 is collected. If the current e is less than the preset first current threshold, the POGO PIN of the charging box is determined. The terminal is not corroded; if the current e is greater than or equal to the first current threshold, it is determined that the POGO PIN terminal of the charging box is corroded. Or, taking Fig. 13 as an example, when the earphone is not placed in the charging box, the current f between the POGO PIN- of the charging box and the ground terminal is collected. If the current f is less than the preset first current threshold, the The POGO PIN terminal is not corroded; if the current f is greater than or equal to the first current threshold, it is determined that the POGO PIN terminal of the charging box is corroded.

In this embodiment, taking the charging box and the earphone as examples, when the POGO PIN of the charging box is not corroded, the impedance of the POGO PIN of the charging box is relatively large, as shown in Figure 15, the POGO PIN- of the charging box and R2 When the POGO PIN uncorroded charging box is put into the uncorroded earphone, since the impedance of the POGO PIN of the earphone is also relatively large, the current between the POGO PIN- and R2 of the charging box will not decrease. It is much smaller. Therefore, when the current between the POGO PIN- and R2 of the charging box is greater than or equal to the fourth current threshold, it is determined that the connector of the second device is not corroded. On the contrary, when the POGO PIN uncorroded charging box is put into the corroded earphone, the current between POGO PIN- and R2 is shunted a lot because the impedance of the POGO PIN of the earphone becomes smaller. Therefore, when the POGO PIN of the charging box is If the current between PIN- and R2 is less than the fourth current threshold, it is determined that the connector of the second device is corroded.

In this embodiment, taking the charging box and the earphone as examples, when the POGO PIN of the charging box is corroded, as shown in Figure 15, the current between POGO PIN- and R2 becomes smaller. When the POGO PIN is not corroded, the current between POGO PIN- and R2 will not be much smaller because the POGO PIN impedance of the earphone is relatively large. Therefore, when the POGO PIN corroded charging box is put into the POGO PIN uncorroded earphone If the current difference before and after is less than or equal to the third difference threshold, it is determined that the POGO PIN of the earphone is not corroded. However, when the POGO PIN corroded charging box is put into the POGO PIN corroded earphone, the current between POGO PIN- and R2 will be much smaller due to the decrease of the POGO PIN impedance of the earphone. Therefore, when the POGO PIN corroded charging box is If the current difference before and after putting in the uncorroded earphone with POGO PIN is greater than the third difference threshold, it is determined that the POGO PIN of the earphone is corroded.

In the method for identifying corrosion of a connector provided by the embodiment of the present application, when the first device and the second device are not connected, the second current between the charging contact and the ground contact of the connector of the first device is collected, and the second current is collected.

If the current difference is greater than the preset third difference threshold, it is determined that the connector of the second device is corroded; if the second current difference is less than or equal to the third difference threshold, it is determined that the connector of the second device is not corroded. By judging the degree of change between the second current and the fourth current, the corrosion state of the connector of the second device is determined, so as to avoid the influence on the performance of the second device when the connector of the second device is corroded.

Embodiment 14

In some scenarios, the corrosion state of the connector can also be identified by the impedance of the connector. In this embodiment, the first parameter includes a first resistance value, and the first resistance value is when the first device and the second device are not connected , collecting the resistance value of the connector of the first device, and determining the corrosion state of the connector of the first device according to the first parameter and the preset threshold, including: if the first resistance value is greater than or equal to the preset first resistance threshold , it is determined that the connector of the first device is not corroded; if the first resistance value is less than the first resistance threshold, it is determined that the connector of the first device is corroded.

In this embodiment, taking the first device as the charging box as an example, as shown in Figures 6 and 7, when the POGOPIN on the charging box is corroded, it is equivalent to connecting a resistor R3 in parallel with the resistor R2. Therefore, when charging When the POGO PIN on the case is corroded, the resistance value of the POGO PIN on the charging case decreases. Based on this principle, the first resistance threshold can be preset to collect the first resistance value of R2 when the earphone is not placed in the charging box. If the first resistance value is greater than or equal to the first resistance threshold, the POGO PIN of the charging box is determined. There is no corrosion.

Based on this principle, the first resistance threshold can be preset to collect the first resistance value of R8 when the earphone is not placed in the charging box. If the first resistance value is greater than or equal to the first resistance threshold, it is determined that the POGO PIN of the earphone has no Corrosion, if the first resistance value is less than the first resistance threshold, it is determined that the POGO PIN of the earphone is corroded.

Wherein, the first resistance value may be obtained by directly collecting the resistance value of the connector of the first device by using a resistance sensor when the first device and the second device are not connected, or it may be obtained by collecting the resistance value of the connector of the first device and the second device when the first device is not connected. The voltage and current on the connector of the first device are calculated and obtained according to the voltage and current, which are not limited in this embodiment of the present application. The first resistance threshold value may be obtained by collecting the resistance values on the connectors of the connectors of the plurality of first devices in the uncorroded and corroded states respectively, and obtained through multiple tests, or according to the principle of equivalent circuit. It can be obtained by calculation, which is not limited in the embodiments of the present application.

The magnitude of the first resistance threshold value can quickly and accurately determine the corrosion state of the connector of the first device.

Embodiment fifteen

On the basis of the twelfth embodiment, the embodiment of the present application focuses on the specific implementation of determining the corrosion state of the connector of the second device when the first parameter and the second parameter are both resistance values. In this embodiment, the first parameter includes a first resistance value, the first resistance value is the resistance value of the connector of the first device collected when the first device and the second device are not connected, and the second parameter includes the second resistance value, the second resistance value is the resistance value of the connector of the first device collected when the first device and the second device are connected through the connector; according to the corrosion state of the connector of the first device and the second parameter, determine the second resistance value Corrosion status of the equipment's connectors, including:

If the connector of the first device is not corroded, determine the corrosion state of the connector of the second device according to the second resistance value and the preset second resistance threshold; or, according to the difference between the first resistance value and the second resistance value The resistance difference between the two determines the corrosion state of the connector of the second device;

If the connector of the first device is corroded, determine the corrosion state of the connector of the second device according to the second resistance value and the preset second resistance threshold; or, according to the difference between the first resistance value and the second resistance value The resistance difference value determines the corrosion state of the connector of the second device.

The second resistance value may be obtained by directly collecting the resistance value of the connector of the first device by using a resistance sensor when the first device and the second device are connected through the connector, or by collecting the first device and the second device through the connection When the connector is connected, the voltage and current on the connector of the first device are collected, and the voltage and current are calculated according to the voltage and current, which are not limited in the embodiments of the present application.

In this embodiment, taking the charging box where the first device is an earphone and the second device as an example, as shown in Figure 17, the POGOPIN uncorroded charging box is equivalent to a resistor R9, as shown in Figure 18, without the POGO PIN Put the uncorroded earphones into the POGO PIN uncorroded charging box, which is equivalent to connecting R8 in parallel with resistor R9. At this time, V4=V5*(R8//R9)/(R7+R8//R9), where R9 represents the earphone’s Resistor for POGO PIN. When the POGO PIN of the charging box is not corroded, the resistance value of R9 is relatively large. Therefore, the resistance of the POGO PIN of the earphone changes relatively small before and after the earphone is placed in the charging box. When the POGO PIN of the charging box corrodes, the resistance value of R9 is relatively small. Therefore, the resistance of the POGO PIN of the earphone changes greatly before and after the earphone is placed in the charging box.

In this embodiment, when the first device is connected to the second device through the connector, the collected second resistance value on the connector of the first device can be determined according to the condition that the connector of the first device is not corroded. The second resistance value and the preset second resistance value threshold value determine the corrosion state of the connector of the second device, and the connector of the second device can also be determined according to the resistance difference between the first resistance value and the second resistance value corrosion state. When the connector of the first device is corroded, the corrosion state of the connector of the second device may be determined according to the second resistance value and the preset second resistance value threshold, or the first resistance value and the second resistance value may be determined according to the corrosion state of the connector of the second device. The degree of change between the values determines the corrosion state of the connector of the second device.

Further, determining the corrosion state of the connector of the second device according to the second resistance value and the preset second resistance threshold, including: if the second resistance value is greater than or equal to the second resistance threshold, determining the connection of the second device The connector is not corroded; if the second resistance value is less than the second resistance threshold, it is determined that the connector of the second device is corroded.

In this embodiment, taking the first device as the charging box and the second device as the earphone as an example, to identify whether the POGO PIN of the earphone is corroded, the principle is that the POGO PIN of the earphone can be equivalent to a resistor, and when the earphone is used When placed in the charging box, it is equivalent to connecting a resistor in parallel to the POGO PIN+ and POGO PIN- of the charging box. When the POGO PIN uncorroded charging box is put into the POGO PIN uncorroded earphone, since the impedance of the POGO PIN of the charging box and the impedance of the POGO PIN of the earphone are relatively large, the equivalent impedance of the POGO PIN of the earphone at this time is relatively large. It is also relatively large; when the POGO PIN corroded earphone is placed in the uncorroded charging box, since the impedance of the POGO PIN of the earphone decreases, the equivalent impedance of the POGO PIN of the earphone decreases at this time.

Based on this principle, the second resistance threshold can be preset, and the second resistance value can be compared with the second resistance threshold to determine the corrosion state of the connector of the second device. For example, when the earphone is put into the charging box, the second resistance value on the POGO PIN of the charging box is collected. When the second resistance value is greater than or equal to the second resistance value threshold, it means that the resistance value on the POGOPIN of the earphone is relatively large. The POGO PIN of the earphone is not corroded; when the second resistance value is less than the second resistance value threshold, it means that the resistance value on the POGO PIN of the earphone is relatively small, and it is determined that the POGO PIN of the earphone is corroded.

It should be noted that the second resistance value threshold may be the same as the first resistance value threshold, the second resistance value threshold may also be different from the first resistance value threshold, and the second resistance value threshold may be smaller than the first resistance value threshold. The embodiment is not limited thereto. The second resistance value threshold may be collected from the resistance values on the connector of the first device when the connector of the first device is not corroded, the connector of the second device is not corroded, and the connector of the second device is corroded, etc. . The resistance value on the connector of the second device is obtained through multiple measurement experiments, or may be calculated according to the equivalent circuit, which is not limited in the embodiments of the present application.

In the method for identifying corrosion of a connector provided in this embodiment of the present application, when the first device and the second device are connected through the connector, the second resistance value on the connector of the first device is collected. If the second resistance value is greater than or equal to the second resistance value resistance value threshold, it is determined that the connector of the second device is not corroded; if the second resistance value is less than the second resistance value threshold, it is determined that the connector of the second device is corroded. Whether the connector of the second device is corroded is simply and accurately determined, so as to reduce the influence of the corrosion of the connector on the second device.

In another embodiment, an implementation manner of determining the corrosion state of the connector of the second device according to the resistance difference between the first resistance value and the second resistance value is mainly introduced, including: if the resistance difference is less than a preset value the fourth difference threshold, it is determined that the connector of the second device is not corroded; if the resistance difference is greater than or equal to the fourth difference threshold, it is determined that the connector of the second device is corroded.

In this embodiment, taking the first device as the charging box and the second device as the earphone as an example, as shown in Figure 11, when the POGOPIN corroded charging box is put into the POGOPIN uncorroded earphone, it is equivalent to the resistance R2 A resistor R4 is connected in parallel with R3. Since the resistance R4 of the POGO PIN of the headset is relatively large, the equivalent resistance of the POGO PIN of the headset box changes little before and after the headset is placed in the headset box. As shown in Figure 12, when the POGO PIN of the charging box is corroded, after putting the corroded earphones, it is equivalent to adding a resistor R5 in parallel on the basis of the resistors R2, R3, and R4. Since the resistance R4 of the POGO PIN of the earphone decreases Small, resulting in a large change in the equivalent resistance of the POGO PIN of the earphone box before and after the earphone is placed in the earphone box.

Based on this principle, if the resistance difference between the first resistance value and the second resistance value is smaller than the preset fourth difference threshold, it is determined that the connector of the second device is not corroded; if the first resistance value and the second resistance value are not corroded If the resistance difference between the resistance values is greater than or equal to the fourth difference threshold, it is determined that the connector of the second device is corroded. That is to say, if the resistance value on the connector of the first device before the first device and the second device are connected through the connector, the resistance value on the connector of the first device after the first device and the second device are connected through the connector The change between the values is small, it is determined that the connector of the second device is not corroded; if the resistance value on the connector of the first device before the first device and the second device are connected through the connector After the two devices are connected through the connector, the change between the resistance values on the connector of the first device is relatively large, and it is determined that the connector of the second device is corroded.

In the method for identifying corrosion of a connector provided by the embodiment of the present application, the first resistance value of the connector of the first device is collected when the first device and the second device are not connected, and the first device and the second device are connected through the connector When the second resistance value of the connector of the first device is calculated, the resistance difference between the first resistance value and the second resistance value is calculated. If the resistance difference is less than the preset fourth difference threshold, the second device is determined. The connector of the first device is not corroded; if the resistance difference is greater than or equal to the fourth difference threshold, it is determined that the connector of the second device is corroded. Before and after the first device is connected to the second device through the connector, the connection of the first device The degree of resistance change on the device can be used to identify the corrosion state of the connector of the second device. This method can simply and accurately identify the corrosion state of the connector of the second device and reduce the corrosion of the connector of the second device. Impact.
