Description

Connecting device

The present invention relates to a connecting device, and more particularly to a connecting device for connecting two electronic devices.

As technology advances, many components can be integrated into a single integrated circuit (IC). Therefore, the size of the electronic device is getting smaller and smaller. In order to further reduce the volume of the electronic device, the number of connection ports of the electronic device is less and less. In some electronic devices, there may be only a single port, and thus it is not possible to connect a plurality of peripheral devices at the same time. Moreover, the transmission speed of the port is also increasing. Many new electronic devices are equipped with new ports. Therefore, peripheral devices with old ports cannot be supported.

The present invention provides a connection device including a DC power socket, a C-type universal serial bus connector, a connection connector, a controller, a first power conversion circuit, and a second power conversion circuit. The DC power socket is for receiving a first input power. The C-type universal sequence busbar connector is coupled to a first electronic device. The connector is coupled to a second electronic device. The controller is coupled to a DC power outlet and a Type C universal serial busbar connector. When the DC power socket receives the first input power and the C-type universal sequence bus connector is coupled to the first electronic device, the controller communicates with the first electronic device to generate a control signal. The first power conversion circuit receives the first input power and converts the first input power according to the control signal to generate a first output power to the C-type universal sequence bus connector. The second power conversion circuit converts the first input power to generate a second output power to the connection connector.

In order to make the objects, features and advantages of the present invention more obvious and obvious, the embodiments are described below, and the detailed description is made in conjunction with the drawings. This written description provides different embodiments to illustrate the technical features of the different embodiments of the present invention. The configuration of each component in the embodiments is for illustrative purposes and is not intended to limit the present invention. In addition, the overlapping portions of the drawings in the embodiments are for the purpose of simplifying the description, and do not mean the relationship between the different embodiments.

Figure 1 is a schematic diagram of the operating system of the author. As shown, the operating system 100 includes a power input device 110, a connection device 120, and electronic devices 130 and 140. In a possible embodiment, the power input device 110 is a power adapter for converting an AC power into a DC power. In this embodiment, the power input device 110 has an input interface 111, a conversion circuit 112, and an output interface 113.

The input interface 111 is for receiving an AC power source. In one possible embodiment, the input interface 111 is a 2-hole connector for receiving utility power. The conversion circuit 112 converts the alternating current power into a direct current power source. In a possible embodiment, the conversion circuit 112 is an AC-DC converter. The output interface 113 is used to output a DC power source. In a possible embodiment, the output interface 113 is a DC power plug.

The connection device 120 has a DC jack 121, a control circuit 122, a Type C universal serial bus connector (USB Type-C) 123, and a connection connector 124. In a possible embodiment, the connecting device 120 is a dongle.

The DC power socket 121 is configured to be coupled to the power input device 110. In the present embodiment, when the power input device 110 is inserted into the DC power socket 121, the DC power socket 121 receives the DC power (or input power) generated by the power input device 110.

The C-type universal sequence bus bar connector 123 is used to couple the electronic device 130. In the present embodiment, the C-type universal sequence bus bar connector 123 is located outside the connection device 120, but is not intended to limit the present creation. In a possible embodiment, the Type C universal sequence busbar connector 123 is integrated in the connection device 120. In this example, a connection line (not shown) is coupled between the C-type universal serial bus bar connector 123 and the electronic device 130. This creation does not limit the type of electronic device 130. In this embodiment, the electronic device 130 is a notebook computer, but is not intended to limit the creation. In other embodiments, any electronic device that can receive an external power source and supply power to an external device can be used as the electronic device 130.

The connection connector 124 is used to couple the electronic device 140. In a possible embodiment, the connector 124 is a Type A universal serial bus connector (USB Type-A), but is not intended to limit the present invention. In another possible embodiment, the connector 124 is a Type C universal serial busbar connector. In the present embodiment, the connection joint 124 is integrated into the connection device 120, but is not intended to limit the creation. In other embodiments, the connection joint 124 may be located outside of the connection device 120.

In the present embodiment, the electronic device 140 is directly inserted into the connection connector 124, but is not intended to limit the creation. In some embodiments, the electronic device 140 is coupled to the connection connector 124 via a connection line (not shown). This creation does not limit the type of electronic device 140. In a possible embodiment, the electronic device 140 is a flash drive. In other embodiments, any peripheral device (such as a smart phone) that can transmit data with the electronic device 130 can be used as the electronic device 140.

The control circuit 122 is responsible for power and data transmission between the power input device 110 and the electronic devices 130 and 140. For example, when the power input device 110 is inserted into the DC power socket 121, the control circuit 122 receives an input power provided by the power input device 110, and determines whether the electronic device 130 is coupled to the C-type universal serial bus connector 123. When the C-type universal serial bus connector 123 is electrically coupled to the electronic device 130, the control circuit 122 communicates with the electronic device 130 to learn the power required by the electronic device 130, and then converts the power input device 110 according to the communication result. The input power is supplied to the electronic device 130.

In the present embodiment, the control circuit 122 also supplies power to the connection terminal 124. The control circuit 122 may directly supply the input power provided by the power input device 110 to the connection connector 124, or first convert the input power provided by the power input device 110, and then supply the converted power to the connection connector 124. Therefore, when the electronic device 140 is electrically coupled to the connection connector 124, the electronic device 140 can receive the power. In a possible embodiment, the power supplied to the electronic device 130 by the control circuit 122 may be the same or different from the power supplied to the electronic device 140. For example, control circuit 122 provides 20V to electronic device 130 and provides 5V to electronic device 140.

In other embodiments, when the electronic device 140 is coupled to the connection connector 124, the electronic device 130 can perform data transmission with the electronic device 140 through the connection device 120. For example, the electronic device 130 may read the data stored by the electronic device 140 through the connection device 120 or write the data to the electronic device 140 through the connection device 120. In another possible embodiment, when the power input device 110 is removed or the input power generated by the power input device 110 is unstable, the control circuit 122 stops supplying power to the electronic devices 130 and 140. In this example, control circuit 122 requires electronic device 130 to provide another input power source and to communicate the input power provided by electronic device 130 to connection connector 124. The control circuit 122 may directly transmit the input power provided by the electronic device 130 to the connection connector 124, or convert the input power provided by the electronic device 130, and then deliver the converted power to the connection connector 124.

Since the connection device 120 not only supplies power to the electronic devices 130 and 140 but also provides a data transmission path between the electronic devices 130 and 140, the number of ports of the electronic device 130 can be expanded. Moreover, current electronic devices are usually equipped with newer connectors (such as Type-C), so products with old connectors (such as Type-A) cannot be supported. However, when the connector 120 is compatible with the old connector, the electronic device (e.g., 130) can communicate with the product having the old connector.

FIG. 2A is a possible embodiment of the control circuit 122 of the present invention. As shown, the control circuit 122 includes a power conversion circuit 210, 230, a controller 220, and a data transmission path 240. The power conversion circuit 210 is coupled between the DC power socket 121 and the C-type universal serial bus connector 123 for receiving the input power VIN _{1 of the} DC power socket 121 and converting the input power VIN ₁ according to a control signal SC. For generating an output power source VO ₁ to the C-type universal sequence bus bar connector 123. In a possible embodiment, the power conversion circuit 210 is a DC-DC converter. In other embodiments, the power conversion circuit 210 includes an Inter-Integrated Circuit interface 211 for receiving the control signal SC.

The power conversion circuit 230 is coupled between the DC power socket 121 and the connection connector 124 for converting the input power source VIN ₁ and supplying the converted power source (ie, the output power source VO ₂ ) to the connection connector 124. The output power source VO ₂ may be the same or different from the output power source VO ₁ . In a possible embodiment, the power conversion circuit 230 is a DC-DC converter. In other embodiments, power conversion circuit 230 can be omitted. In this example, the DC power socket 121 is directly coupled to the connection connector 124 for providing the input power source VIN ₁ to the connection connector 124.

The data transmission path 240 is coupled between the C-type universal sequence bus bar connector 123 and the connection connector 124. When the C-type universal serial bus bar connector 123 is electrically connected to the electronic device 130 and the connection connector 124 is electrically connected to the electronic device 140, the electronic device 130 performs data transmission with the electronic device 140 through the data transmission path 240. For example, the electronic device 130 may provide data to the electronic device 140 through the data transmission path 240 or receive data from the electronic device 140 through the data transmission path 240.

In a possible embodiment, the data transmission path 240 transmits a differential signal pair. In some embodiments, the data transfer path 240 couples the D+/D- pins of the C-type universal serial busbar header 123 to the D+/D- pins of the connection header 124. In this example, the signal on the D+/D- pin is compliant with the USB 2.0 specification. In other embodiments, the data transmission path 240 may be coupled to the SSRX/SSTX pin of the C-type universal sequence bus connector 123 and the D+/D- pin of the connection connector 124. In this example, the SSRX/SSTX pin is compliant with USB 3.0 regulations.

The controller 220 is coupled to the DC power socket 121 and the C-type universal serial bus connector 123 for receiving the input power VIN ₁ and hand shaking with the electronic device 130 through the C-type universal serial bus connector 123. In a possible embodiment, the input power source VIN ₁ is the operating power source of the controller 220. Therefore, when the DC power outlet 121 provides the input power VIN ₁ , the controller 220 starts to operate. In this example, the controller 220 determines whether the electronic device 130 is electrically connected to the C-type universal sequence bus bar connector 123 according to the level of a specific pin of the C-type universal sequence bus bar connector 123. In a possible embodiment, the specific pin refers to the configuration channel pin CC of the C-type universal sequence bus bar connector 123.

When the electronic device 130 is electrically connected to the C-type universal serial bus connector 123, the controller 220 communicates with the electronic device 130 through the configuration channel pin CC to inquire about how much power the electronic device 130 needs. In this example, the controller 220 generates a control signal SC for instructing the power conversion circuit 210 to generate a suitable output power source VO ₁ based on the communication result. Therefore, the electronic device 130 can receive a suitable operating power through the C-type universal serial bus bar connector 123.

In addition, when the DC power socket 121 provides the input power VIN ₁ , the power conversion circuit 210 converts the input power VIN ₁ for generating the output power VO ₂ to the connection connector 124. Therefore, when the electronic device 140 is inserted into the connection connector 124, the electronic device 140 can immediately receive the output power VO ₂ . Moreover, the electronic device 130 can also communicate with the electronic device 140 through the data transmission path 240.

FIG. 2B is another embodiment of the control circuit 122 of the present invention. Fig. 2B is similar to Fig. 2A except that the control circuit 122 of Fig. 2B has a power switch 250. As shown, the power switch 250 is coupled between the C-type universal serial bus connector 123 and the connection connector 124 for transmitting an input power provided by the electronic device 130 to the electronic device 140.

3A-3C are schematic diagrams showing the operation mode of the control circuit 122. Referring to FIG. 3A, when the power input device 110 is coupled to the DC power socket 121, the DC power socket 121 receives the input voltage VIN ₁ from the power input device 110, and supplies the input power VIN ₁ to the power conversion circuits 210, 230, and Controller 220. At this time, the controller 220 operates in a first mode. In this mode, the controller 220 determines whether the C-type universal sequence bus bar connector 123 is electrically coupled to the electronic device 130 according to the voltage of the configuration channel pin CC.

In a possible embodiment, when the voltage of the configuration channel pin CC is equal to a predetermined voltage, it indicates that the electronic device 130 has been electrically connected to the C-type universal sequence bus bar connector 123. Therefore, the controller 220 communicates with the electronic device 130 through the configuration channel pin CC to learn the power required by the electronic device 130. The controller 220 generates a control signal SC based on the communication result. The power conversion circuit 210 converts the input power source VIN ₁ according to the control signal SC to generate a suitable output power source VO ₁ to the C-type universal sequence bus bar connector 123.

In the first mode, the power input device 110 that provides the input power source VIN ₁ is a power role, and the electronic device 130 is a data role. In addition, the C-type universal sequence busbar connector 123 can be considered as a downstream facing port. In addition, since the input power source VIN ₁ reaches a predetermined value, the controller 220 does not turn on the power switch 250.

Referring to FIG. 3B, when the electronic device 140 is electrically connected to the connection connector 124, the controller 220 enters a second mode. In this mode, the connection connector 124 provides an output power source VO ₂ to the electronic device 140. Therefore, the connection joint 124 is also used as the next line. In addition, in the second mode, the electronic device 130 performs data transmission with the electronic device 140 through the data transmission path 240. At this time, the power of the electronic device 140 is from the power input device 110, and the data of the electronic device 140 is from the electronic device 130. In this mode, the input power supply VIN ₁ up to a preset value, the controller 220 so that power switch 250 is still turned on.

Referring to FIG. 3C, when the power input device 110 is removed or the input power source VIN _{1 is} unstable, the input power source VIN ₁ will be less than a preset value. Since the input power source VIN _{1 does} not reach the preset value, the controller 220 enters a third mode. In the third mode, the controller 220 turns on the power switch 250 such that the power switch 250 transmits the input power source VIN ₂ to the electronic device 140. In this example, input power source VIN ₂ is provided by electronic device 130.

When the input power source VIN _{1 does} not reach the preset value, the power conversion circuits 210 and 230 are suspended, and the output power sources VO ₁ and VO _{2 are} temporarily not provided. In other embodiments, when the power input device 110 is reinserted into the DC power socket 121, or the input power source VIN ₁ reaches a preset value, the controller 220 does not turn on the power switch 250, so that the power switch 250 does not transmit the input power source VIN ₂ to Electronic device 140. At this time, since the input power source VIN ₁ has reached the preset value, the power conversion circuits 210 and 230 start to operate, and the output power sources VO ₁ and VO _{2 are} again supplied to the electronic devices 130 and 140.

In the third mode, the controller 220 changes the role of the electronic device 130 to switch the role of the electronic device 130 from the data role to the power role. At this time, the C-type universal sequence bus bar connector 123 is regarded as an upstream facing port. Since the C-type universal sequence bus bar connector 123 can be used not only as a downlink but also as an uplink port, the C-type universal sequence bus bar connector 123 is called a dual role port (DRP).
