Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a schematic block diagram illustrating a connector that may be adapted for use with a terminal having an interface according to an exemplary embodiment. As shown in fig. 1, the joint includes:

A first end 11 for connecting an interface of a terminal;

a second end 12 for connecting a power line;

a third terminal 13 for connecting an audio input/output component;

Wherein the first terminal 11 includes a power pin 111 and a data pin 112, the power pin 111 is connected to the second terminal 12, and the connector further includes:

and a first connection module 14 connected to the data pin 112, and configured to connect the data pin to the second terminal 12 when receiving a first signal from the data pin 112, and connect the data pin to the third terminal 13 when receiving a second signal from the data pin 112.

In one embodiment, the first end of the connector may interface with a processor in the terminal and a power management chip, the power management chip needs to obtain charging handshaking information, such as charging voltage, charging current, and the like, before receiving a charging signal from the power line, and the handshaking information belongs to data and needs to be input to the terminal through a data pin. When a user listens to music in the terminal through an audio input/output component, such as a headset, audio is also data and needs to be output to the audio input/output component through a data pin.

in one embodiment, the first end may be a male port of the connector, the second end may be a female port of the connector, and the third end may be another interface different from the male port and the female port, so that the connector can simultaneously connect the interface, the power cord and the audio input/output module by providing the third interface. And the first connection module can switch the conduction of the first end and the second end or the conduction of the first end and the third end according to different received signals.

Since the second terminal is always on with the power pin in the first terminal, the processor in the terminal can detect once the electrical signal is present at the second terminal. When the second terminal is detected to have an electrical signal (for example, a voltage signal), it may be determined that the second terminal is connected to a power line, so that the first signal may be transmitted to the first connection module, the third terminal and the data pin in the first terminal are temporarily disconnected, and the second terminal and the data pin are connected, so that the data pin may receive a charging handshake signal input by the power line.

In one embodiment, the received charging handshake signals may be forwarded by the processor to the power management chip, so that the power management chip may be configured according to the charging handshake information to receive the power signals input by the power line. And after the processor receives the charging handshake signal, the processor does not need to receive data from the power line, so that the processor can transmit a second signal to the first connection module, disconnect the data pin in the first terminal from the second terminal, and reconnect the third terminal and the data pin in the first terminal, so that a user can continue to listen to music in the terminal through the audio input/output component. And because the time quantum of receiving the information of charging handshake is very short, so the time of breaking off the data pin in third end and the first end is also very short, and the user is in the in-process of listening to the music, when the second end inserts the power cord, can hardly influence the effect of listening to of music, can realize charging to the terminal when listening to the music.

therefore, according to the connector in the embodiment, when the connector is connected to the interface listening terminal for music, the terminal can be charged simultaneously, a user does not need to pull out the audio input/output component connected to the connector, and the use experience of the user on the interface is improved.

it should be noted that the first connection module 14 shown in fig. 1 is a single-pole double-throw switch, which is only an illustration, and other structures having a switching function may be adopted as the first connection module 14.

in fig. 2, the connector may be adapted to a Type-C interface, the audio input/output component may be a 3.5 mm-sized headset, and the DET1 pin of the headset is connected to the CC pin and the VCONN pin of the connector, so that whether the headset is plugged into the connector or not can be detected through the connection relationship. The LEFT pin and the RIGHT pin (corresponding to LEFT and RIGHT channels) are respectively connected to a Dp1 pin and a Dn1 pin, wherein the Dp1 pin and the Dn1 pin are data pins shown in fig. 1. The VBUS pin in the connector is the power pin shown in fig. 1. The functions of the pins GND, SSTXp1, SSTXp2, SSRXp1, SSRXp2, SBU1, SBU2, etc. in the connector are similar to those in the related art, and are not described herein again.

FIG. 3 is a schematic block diagram illustrating another joint according to an exemplary embodiment. As shown in fig. 3, on the basis of the embodiment shown in fig. 1, the joint further includes:

a first buffer register module 15, connected to the first connection module 14 and the data pin 112, for registering the first signal or the second signal.

in one embodiment, the first signal may be a high or low level signal and the second signal may also be a high or low level signal, but the two remain different. Through the first buffer register module, the state of receiving the first signal can be kept in the time from the time when the first connection module receives the first signal to the time when the first connection module receives the second signal. For example, the second terminal may be kept conductive with the data pin after receiving the first signal of high level until receiving the second signal of low level. Similarly, the third terminal may be kept in conduction with the data pin after receiving the second signal of low level until receiving the first signal of high level. Therefore, the connection is prevented from being switched when the first connection module does not receive the signal due to the influence of factors such as noise and the like.

FIG. 4 is a schematic block diagram illustrating yet another joint according to an exemplary embodiment. As shown in fig. 4, on the basis of the embodiment shown in fig. 1, the joint further includes:

And a second connection module 16 connected to the third terminal 13, for grounding the third terminal 13 when receiving the second signal, and disconnecting the third terminal 13 from the ground when receiving the first signal.

in one embodiment, when the terminal is charged, the charging current may cause interference to an audio signal transmitted from the data pin to the third terminal, and the interference may be reduced by grounding the third terminal when the terminal is charged through the second connection module, thereby ensuring a listening effect of a user.

In one embodiment, a resistor may be further disposed between the third terminal and the ground, so that on one hand, the voltage of the third terminal may be raised to a required level, and on the other hand, the mobile phone housing may be used as the ground, and the current transmitted from the third terminal to the mobile phone housing may be prevented from being too large by the resistor, thereby protecting a user to a certain extent.

FIG. 5 is a schematic block diagram illustrating yet another joint according to an exemplary embodiment. As shown in fig. 5, on the basis of the embodiment shown in fig. 4, the joint further includes:

and a second buffer register module 17, connected to the second connection module and the data pin, for registering the first signal or the second signal.

Similar to the embodiment shown in fig. 3, the second buffer module can avoid the influence of noise and other factors from causing the second connection module to switch connection when not receiving a signal.

FIG. 6 is a schematic block diagram illustrating yet another joint according to an exemplary embodiment. As shown in fig. 6, the embodiment shown in fig. 5 may be combined with the embodiment shown in fig. 3. Of course, it is also possible to combine the embodiment shown in fig. 4 with the embodiment shown in fig. 3.

In step S71, detecting whether a power signal exists at the second end, and if so, proceeding to step S72;

In step S72, generating a first signal, transmitting the first signal to the first connection module;

In step S73, acquiring charging handshake information from the power supply signal;

In step S74, receiving the power supply signal according to the charging handshake information;

In step S75, a second signal is generated and transmitted to the first connection module.

in one embodiment, the above steps may all be performed by the terminal where the Type-C interface is located, and specifically, the steps S71, S72, S73 and S75 may be performed by a processor in the terminal, and the step S74 may be performed by a power management chip in the terminal. After the processor executes step S73, the charging handshake information may be transmitted to the power management chip, and then step S75 may be executed without waiting for the execution of step S74.

FIG. 8 is a schematic flow chart diagram illustrating another method of controlling connector charging in accordance with an exemplary embodiment. As shown in fig. 8, on the basis of the embodiment shown in fig. 7, the method further includes:

In step S76, after determining that the power signal exists, determining whether the voltage of the power signal is greater than a predetermined voltage, and if so, performing step S72 to generate a first signal.

in one embodiment, since the voltage at the power line input may be unstable and the battery may be damaged by charging with an unstable voltage, especially a lower voltage, after determining that the power signal is present, i.e. after determining that the voltage signal is present at the first terminal, it may be further determined whether the voltage is large enough, e.g. larger than a preset voltage, and only if it is larger than the preset voltage, it is determined that the voltage at the power line input is suitable for charging, otherwise no charging is performed.
