A partition (not shown) made of an insulator may be provided between the hollow portion of the positive terminal 16 and the plug body 11.

FIG. 4 is a block diagram showing the internal configuration of the AC adapter main body 20. The rectifying / smoothing circuit 21 is connected to the input unit 30. The rectifying / smoothing circuit 21 includes, for example, a bridge diode and a capacitor, rectifies the AC current of the AC power supply input from the input unit 30 by the bridge diode, smoothes it by the capacitor, and outputs it as a DC current.

The power conversion circuit 23 is connected to the rectifying / smoothing circuit 21. The power conversion circuit 23 includes a switching element, adjusts the power (voltage drops) by intermittently controlling (switching) the direct current output by the rectifying / smoothing circuit 21 with the switching element, and outputs it as an alternating current.

The rectifying / smoothing circuit 25 is connected to the power conversion circuit 23. The rectifying / smoothing circuit 25 includes, for example, a bridge diode and a capacitor, rectifies the alternating current output by the power conversion circuit 23 by the bridge diode, smoothes it by the capacitor, and outputs it as a direct current.

Further, the rectifying / smoothing circuit 25 is connected to the wiring L1 (16B) and the wiring L2 (14B). The wiring L1 is connected to the positive terminal 16 of the DC plug 10. The wiring L2 is connected to the negative terminal 14 of the DC plug 10. The rectifying / smoothing circuit 25 rectifies / smoothes the alternating current output from the power conversion circuit 23 and outputs it from the DC plug 10.

The control unit 26 is a circuit connected to the power conversion circuit 23. Further, the control unit 26 is connected to the DC plug 10 via the wiring L3 (17B). The wiring L3 is connected to the auxiliary terminal 17 of the DC plug 10.

The control unit 26 sends a control signal as an operation command to the power conversion circuit 23 according to the connection state of the auxiliary terminal 17, and controls the operation of the power conversion circuit 23 as the power conversion unit. More specifically, the control unit 26 detects whether or not the DC jack of the load device is connected to the DC plug 10 via the auxiliary terminal 17, and depending on whether or not the DC jack is connected, The operation of the power conversion circuit 23 is controlled or stopped.

For example, the control unit 26 detects whether or not the positive terminal 16 and the auxiliary terminal 17 have the same potential, and when the positive terminal 16 and the auxiliary terminal 17 have the same potential, the DC jack is connected. It detects that it is present and sends a control signal as an operation command.

The control unit 26 includes a control circuit 27, a stop circuit 28, a release circuit 29, and a voltage detection circuit 31.

The release circuit 29 is connected to the auxiliary terminal 17 of the DC plug 10. The release circuit 29 detects whether or not the DC jack of the load device is connected to the DC plug 10 via the auxiliary terminal 17. The release circuit 29 sends a release signal depending on whether or not the DC jack is connected.

Further, the release circuit 29 is connected to the stop circuit 28. The release circuit 29 sends a release signal to the stop circuit 28 when the DC jack is connected to the DC plug 10. When the DC jack is not connected to the DC plug 10, the release circuit 29 stops sending the release signal to the stop circuit 28.

The stop circuit 28 is connected to the control circuit 27. The stop circuit 28 sends a stop signal to the control circuit 27 in response to the release signal sent from the release circuit 29.

Specifically, the stop circuit 28 sends a stop signal to the control circuit 27 when the release signal is not received. When the stop circuit 28 receives the release signal, the stop circuit 28 stops sending the stop signal to the control circuit 27.

The control circuit 27 is connected to the power conversion circuit 23. The control circuit 27 sends a control signal to the power conversion circuit 23 in response to the stop signal from the stop circuit 28. Specifically, when the control circuit 27 receives the stop signal, the control circuit 27 stops the transmission of the control signal to the power conversion circuit 23 and stops the operation of the power conversion circuit 23.

When the control circuit 27 has not received the stop signal, the control circuit 27 sends a control signal to the power conversion circuit 23 to control the operation of the power conversion circuit 23. For example, the control circuit 27 controls the operation of the switching element of the power conversion circuit 23 on and off when the stop signal is not received.

The voltage detection circuit 31 as a monitor unit is connected to the auxiliary terminal 17 of the DC plug 10 via the wiring L3. The voltage detection circuit 31 detects the voltage of the wiring L3 when the DC jack is connected to the DC plug 10 and the operation of the power conversion circuit 23 is controlled. That is, the control unit 26 can detect and monitor the supply voltage output from the DC plug 10 via the auxiliary terminal 17.

Further, the voltage detection circuit 31 is connected to the control circuit 27. The voltage detection circuit 31 sends a detection signal indicating the detection result of the supply voltage to the control circuit 27.

For example, the control circuit 27 of the control unit 26 transmits an adjustment signal as an adjustment command for adjusting the supply voltage to the power conversion circuit 23 according to the detection signal as a monitoring result from the voltage detection circuit 31. To adjust the supply voltage. As a result, the feedback control of the supply voltage becomes possible, and the supply voltage can be output at a more stable voltage.

Further, according to the present embodiment, by detecting the supply voltage by the auxiliary terminal 17, the supply voltage is actually supplied to the load device as compared with the case where the supply voltage after power conversion is detected in the AC adapter main body 20, for example. The voltage to be generated can be detected more accurately. For example, feedback control that compensates for the influence of the voltage drop caused by passing through the wiring L3 from the AC adapter main body 20 to the DC plug 10 becomes possible, and improvement in the accuracy of the feedback control of the supply voltage can be expected.

The output from the rectifying / smoothing circuit 21 provides an operating power source for the control circuit 27, the stop circuit 28, the release circuit 29, and the voltage detection circuit 31.

The control unit 26 does not have to have the voltage detection circuit 31.

The connection of the DC jack 40 to the DC plug 10 will be described with reference to FIGS. 5 and 6. In this embodiment, a case where the DC jack 40 is a DC jack conforming to the JEITA standard RC-5320 will be described.

FIG. 5 is a cross-sectional view of the DC plug 10 and the DC jack when the DC jack is not connected to the DC plug 10. In FIG. 5, the positive terminal 41 shows a metal center electrode provided on the DC jack 40. The center electrode 41 is formed in a shape that can be fitted to the inner side surface of a hollow cylindrical shape formed by the positive terminal 16 and the auxiliary terminal 17 of the DC plug 10.

In FIG. 5, the minus terminal 42 indicates the minus terminal of the DC jack 40. The minus terminal 42 is provided in a shape that can be fitted to the outer surface of the minus terminal 14 of the DC plug 10.

In the state of FIG. 5, as described above, the auxiliary terminal 17 of the DC plug 10 is provided apart from the positive terminal 16 and is electrically separated from the positive terminal 16. In other words, the positive terminal 16 and the auxiliary terminal 17 are in an open state. In this case, the positive terminal 16 and the auxiliary terminal 17 are in different potential states.

FIG. 6 is a cross-sectional view of the DC plug 10 and the DC jack 40 when the DC jack 40 is connected to the DC plug 10. As shown in FIG. 6, the center electrode 41 of the DC jack 40 is housed and fitted inside the positive terminal 16 and the auxiliary terminal 17 of the DC plug 10. Further, the negative terminal 42 of the DC jack 40 is fitted to the outside of the negative terminal 14 of the DC plug 10.

In the state of FIG. 6, the positive terminal 16 of the DC plug 10 and the positive terminal 41 of the DC jack 40 are in contact with each other, and the negative terminal 14 of the DC plug 10 and the negative terminal 42 of the DC jack 40 are in contact with each other. As a result, the electric power that has passed through the AC adapter main body 20 is relayed by the DC plug 10 and output to the load device side.

Further, in the state of FIG. 6, the positive terminal 16 and the auxiliary terminal 17 as one terminal of the DC plug 10 are both in contact with the positive terminal 41 of the DC jack 40 (that is, the terminal of the opposite connector). Therefore, the positive terminal 16 and the auxiliary terminal 17 of the DC plug 10 are short-circuited. In this case, the auxiliary terminal 17 is at the same potential as the positive terminal 16.

As shown in FIG. 6, the release circuit 29 (see FIG. 4) of the AC adapter main body 20 has the auxiliary terminal 17 at the same potential as the positive terminal 16 when the DC jack 40 is connected to the DC plug 10. Is detected and a release signal is sent.

When the stop circuit 28 (see FIG. 4) receives the release signal, the stop circuit 28 stops sending the stop signal. When the transmission of the stop signal is stopped, the control circuit 27 (see FIG. 4) sends a control signal to the power conversion circuit 23 (see FIG. 4) to control the operation of the switching element. As a result, the DC voltage output from the rectifying / smoothing circuit 21 is power-adjusted by the power conversion circuit 23, and is output from the DC plug 10 via the rectifying / smoothing circuit 25.

As shown in FIG. 5, the release circuit 29 of the AC adapter main body 20 detects that the auxiliary terminal 17 is in a potential state different from that of the positive terminal 16 when the DC jack 40 is not connected to the DC plug 10. Stop sending the release signal.

When the stop circuit 28 does not receive the release signal, the stop circuit 28 sends a stop signal. When the control circuit 27 receives the stop signal, it does not send a control signal to the power conversion circuit 23 and does not control the operation of the switching element. As a result, the DC voltage output from the rectifying / smoothing circuit 21 is not output from the power conversion circuit 23.

FIG. 7 is a circuit diagram showing an example of the circuit configuration of the release circuit 29 in the circuit 20A (see FIG. 4) of this embodiment. The release circuit 29 has a resistor R1 and a resistor R2 connected in series with each other between a node A connected to a power source (not shown) for supplying a power supply voltage Vcc and a node B connected to a ground potential. ing. Further, the release circuit 29 has a resistor R1 and a resistor R3 connected in parallel with the resistor R2 between the node A and the node B.

The release circuit 29 has a transistor Q1 arranged between the resistor R1 and the node B. The transistor Q1 is, for example, an NPN bipolar transistor in which the collector is connected to the resistor R1, the emitter is connected to the node B, and the base is connected between the resistors R1 and R2.

The release circuit 29 is connected to the stop circuit 28 at a node C between the resistor R3 and the transistor Q1. Further, the release circuit 29 is connected to the auxiliary terminal 17 of the DC plug 10 at the node D between the resistor R1 and the resistor R2.

As described above, when the DC jack 40 is not connected to the DC plug 10 (see FIG. 5), the auxiliary terminal 17 of the DC plug 10 is in the open state. Therefore, a current is supplied to the base of the transistor Q1 via the resistor R1, and the transistor Q1 is in the ON state. In this case, the node C has a low potential. In this way, the state in which the node C has a low potential can be set to the state in which the transmission of the release signal to the stop circuit 28 is stopped.

Further, as described above, when the DC jack 40 is connected to the DC plug 10 (see FIG. 6), the auxiliary terminal 17 is short-circuited with the positive terminal 16 and has the same potential. When the DC jack 40 is connected to the DC plug 10, the positive terminal 16 is connected to the ground voltage GND (see FIG. 4) of the circuit 20A via the circuit in the load device connected to the DC jack 40. Has been done. That is, the positive terminal 16 and the auxiliary terminal 17 have a ground potential.

Therefore, the node D has a ground potential, no current is supplied to the base of the transistor Q1, and the transistor Q1 is in the off state. As a result, no current flows from the resistor R3 to the ground potential GND side, so that the node C has a high potential. In this way, the state in which the node C has a high potential can be set to the state in which the release signal is sent to the stop circuit 28.

The circuit configuration of the release circuit 29 is not limited to the configuration shown in FIG. 7, and other configurations such as a configuration including an operational amplifier may be adopted.

As described above, in the AC adapter 100 including the power conversion circuit 23 of this embodiment, when the load device is not connected to the DC plug, the operation of the power conversion circuit 23 can be stopped. As a result, it is possible to reduce the power consumption while the load device is not connected, that is, during standby. In particular, it is possible to reduce power consumption due to the operation of the switching element in the power conversion circuit 23 during standby.

Further, in the AC adapter 100 of this embodiment, whether or not the AC adapter 100 is connected to the load device can be detected via the auxiliary terminal 17 provided on the DC plug 10.

For example, in the conventional example, in order to detect whether or not the AC adapter is connected to the load device, a dedicated circuit including, for example, a resistor for detecting a voltage may be provided on the load device side. In such a case, the AC adapter can be used only in the load device provided with the dedicated circuit.

Since the AC adapter 100 of this embodiment can be detected via the auxiliary terminal 17 provided on the DC plug 10, it is not necessary to provide the dedicated circuit as described above on the load device side. Therefore, the AC adapter 100 can be applied to any device that can be plugged and connected to the DC plug 10 without limiting the load device. For example, the same AC adapter 100 can be used for various devices as long as the connectors conform to a common standard.

Therefore, according to the AC adapter 100 of the present embodiment, it is possible to provide a power conversion supply connector device and a power conversion device that are versatile and can reduce power consumption during standby.

The structure of the auxiliary terminal 17 is not limited to the case shown in the above embodiment. For example, the auxiliary terminal 17 may be provided adjacent to the negative terminal 14. Further, for example, when the DC plug 10 is a DC plug of another standard, it may be provided adjacent to the positive terminal provided on the outer surface of the terminal supporting portion 15. That is, the auxiliary terminal 17 may be provided in the same plane as any of the terminals provided on the inner side surface or the outer side surface of the terminal supporting portion 15.

Further, the shape and size of the auxiliary terminal 17 are not limited to the cases shown in the above embodiment. For example, the auxiliary terminal 17 may have the same size as the positive terminal 16 and may be larger than the positive terminal 16.

Further, as shown in the above embodiment, the DC plug 10 and the DC jack are provided by providing either the auxiliary terminal 17 or the positive terminal 16 at a position far from the tip of the electrode portion 13 in the insertion direction in the insertion connection. It is possible to prevent the supply voltage from being supplied in a state where the connection with the 40 is incomplete.

In other words, of the ends of either the auxiliary terminal 17 or the positive terminal 16, the end of the DC plug 10 facing the DC jack 40 is the end of the other terminal. It suffices if it is provided offset from the end of the. In the embodiment, an example is shown in which the end portion of the auxiliary terminal 17 on the tip end side is offset from the end portion of the plus terminal 16 on the tip end side.

As a result, when the connection between the DC plug 10 and the DC jack 40 is incomplete and the center electrode 41 of the DC jack 40 does not reach the auxiliary terminal 17, the supply voltage is prevented from being supplied. be able to.

An example in which the control unit 26 has a control circuit 27, a stop circuit 28, a release circuit 29, and a voltage detection circuit 31 has been described, but the present invention is not limited to this.
