(Embodiment 1)

(1) Summary First, referring to FIGS. 1 and 4, the outline of the USB (Universal Serial Bus) outlet 10 of this embodiment will be described.

The USB socket 10 of this embodiment is a device that can be connected to the USB connector 91 of the device 9. The USB socket 10 is a device that supplies power to the device 9 (for example, a smart phone, etc.) through the USB connector 91 in a state of being connected to the USB connector 91. The device 9 uses the power supplied from the USB socket 10 to charge the storage battery 92 (see FIG. 4) included in the device 9, for example.

The USB socket 10 of the present embodiment is, for example, a wiring tool installed on an installation object 81 such as a wall surface of a building. These USB sockets 10 are always electrically connected to a power source (system power supply, etc.), similarly to general outlet devices that output AC voltages such as 100V or 200V, and are basically always in a energized state. Therefore, in the user, only by connecting the device 9 to the USB socket 10, power can be supplied to the device 9 from the USB socket 10 via the USB connector 91.

Here, if it is a general socket device that outputs AC voltage such as 100V or 200V, for example, when charging devices 9 such as smartphones, in order to supply power to the devices 9, a power source that converts AC voltage to DC voltage must be used Adapter. In contrast, if the USB socket 10 of this embodiment is used, the power adapter can be directly connected to the USB socket 10 to the USB connector 91 of the device 9 to supply power to the device 9. Therefore, according to the USB socket 10, even if it does not have a power adapter, for example, devices 9 such as smart phones can still be charged, and since a power adapter is not required, the periphery of the USB socket 10 is clean.

The USB socket 10 of this embodiment includes a connecting portion 2, a power supply circuit 11, a housing 3, and a notification portion 102. The connecting portion 2 can be electrically connected to the USB connector 91 of the device 9. The power supply circuit 11 supplies electric power to the device 9 from the connection unit 2. The casing 3 houses the power supply circuit 11. The notification unit 102 notifies if the monitored value exceeds the threshold value. The monitoring value consists of the magnitude of the current supplied to the device 9, the cumulative value of the current supplied to the device 9, the magnitude of the power supplied to the device 9, the amount of power supplied to the device 9, and the length of time the power is supplied to the device 9 At least one of them.

According to this configuration, if the monitoring value such as the magnitude of the current supplied from the power supply circuit 11 to the device 9 exceeds a threshold value, the notification unit 102 will notify. Therefore, for example, when an excessive current or power exceeding the rated output (current or power) of the power supply circuit 11 is supplied to the device 9 from the USB socket 10, the user can be notified of this phenomenon. Therefore, the abnormality of the monitoring value such as the magnitude of the current supplied by the device 9 can be notified early, and the reliability of the USB socket 10 can be improved. As a result, it is possible to provide a USB socket 10 that can easily achieve an improvement in reliability.

That is, in this embodiment, the USB connector 91 of the device 9 is a USB plug, so the connecting portion 2 of the USB socket 10 is a jack that can be connected to the USB plug. Therefore, the connection port 4 of the housing 3 of the USB socket 10 is included in the connection portion 2.

The “equipment” mentioned in the present invention is an electrical device (device, machine, and system) that can be electrically connected to the USB socket 10 and receive power supply from the USB socket 10. The device 9 includes, for example, information terminals such as smart phones, tablet terminals, or wearable terminals, mobile phone batteries, mobile phones, cameras, fans, flashlights, or TV receivers. The USB socket 10 supplies DC power by applying a DC voltage to the device 9, so the device 9 is a device corresponding to the DC input. Among such devices 9, devices 9 such as smartphones, tablet terminals, or wearable terminals include a storage battery 92 and have a function of charging the storage battery 92 with electric power supplied from the USB socket 10. Hereinafter, the device 9 having the function of charging the storage battery 92 may be referred to as a "chargeable device". In this embodiment, unless otherwise specified, the description is given by taking a case where the device 9 connected to the USB socket 10 is a rechargeable device 9 as an example.

In this embodiment, the USB socket 10 is fixed to the installation target 81. The "installation object" mentioned in the present invention is a member that fixes the USB socket 10, and includes, for example, structures such as walls, ceilings, or floors of buildings, or furniture (including decorations) such as tables, shelves, or counters. The USB socket 10 is, for example, installed in residential facilities such as single-family houses or multi-family houses, or non-residential facilities such as offices, shops, schools, factories, hospitals, or nursing facilities. In this embodiment, as an example, it is assumed that the USB socket 10 is a built-in type wiring appliance and is attached to an installation target 81 formed by the wall surface of a residential facility. In particular, the USB socket 10 is assumed to be an indoor wiring appliance used inside a building.

Hereinafter, the direction perpendicular (orthogonal) to the horizontal plane in the state where the USB socket 10 is fixed to the wall surface of the installation target 81, that is, the residential facility, will be described as the "up and down direction" of the USB socket 10 in some cases. In addition, the lower part when the USB socket 10 is viewed from the front may be described as the “lower part” of the USB socket 10. The direction perpendicular to the vertical direction and parallel to the surface (wall surface) of the installation target 81 is referred to as the "left and right direction" of the USB socket 10, and the right side when the USB socket 10 is viewed from the front is referred to as the "right side" of the USB socket 10 ", taking the left side as the "left side" of the USB socket 10 to explain the situation.

That is, whether the two values are equal or not can be arbitrarily changed according to the setting of the reference value, etc., so there is no technical difference between "above" or "greater". Similarly, in "not full", it can also be synonymous with "below".

(2.2) Basic composition Next, referring to FIGS. 1 to 3B, the basic structure of the USB socket 10 of this embodiment will be described.

As described above, in the present embodiment, as an example, the USB socket 10 is a built-in wiring appliance and is attached to the installation target 81 formed by the wall surface of the residential facility. That is, the USB socket 10 is fixed to the installation object 81 and is configured as a wiring tool that can be connected to the wiring L1 (refer to FIG. 4) passing through the back side of the installation object 81. In particular, this USB socket 10 is an embedded type that fixes the housing 3 to the installation object 81 in a state where at least a part of the casing 3 is inserted into the construction hole 82 (refer to FIG. 3A) formed in the installation object 81的wiring appliances.

In addition, the USB socket 10 is provided with a terminal portion 16 (refer to FIG. 4) for connecting to the wiring L1. For example, the wiring L1 that is wound around the wall surface (installation object 81) is connected to the terminal portion 16, thereby being connected via the wiring L1. It is electrically connected to the system power supply and other power sources. The wiring L1 can be directly connected to the power supply (system power supply, etc.), or indirectly connected via a switchboard, etc.

In this embodiment, as an example, the USB socket 10 is electrically connected to a single-phase 100V, 60Hz commercial AC power supply (system power supply) through the wiring L1 by connecting the wiring L1 to the terminal portion 16. Here, the USB socket 10 is connected to an AC power supply (system power supply) via a switchboard, and if the circuit breakers (main circuit breaker and branch circuit breaker) of the switchboard are in a conducting state, they are always in an energized state. Therefore, the USB socket 10 is basically always in a state capable of supplying power to the device 9.

In addition, in this embodiment, as an example, a dual-port (dual-port) type USB receptacle 10 that can connect two USB connectors 91 is illustrated. That is, the USB socket 10 of this embodiment is provided with a plurality of (here, two) connecting portions 2 (including the connecting port 4) for connecting with the USB connector 91, and the device can be connected to the device from the plurality of connecting portions 2 9Supply power. Therefore, the USB socket 10 can simultaneously supply power to the plurality of devices 9 in a state where the USB connectors 91 of the plurality of devices 9 are connected. In the present embodiment, when a plurality of (here, two) connection parts 2 are distinguished, each connection part 2 may be referred to as a first connection part 21 and a second connection part 22, respectively. Similarly, when a plurality of connection ports 4 (here, two) are distinguished, each connection port 4 may be referred to as a first connection port 41 and a second connection port 42 respectively.

The USB socket 10, as shown in FIGS. 2A and 2B, includes a power supply circuit 11 and a casing 3. Fig. 2B is an enlarged view of the vicinity of the first connection port 41 in Fig. 2A. The power supply circuit 11 includes a circuit board (printed wiring board) and various electronic components mounted on the circuit board. The power supply circuit 11 converts the AC voltage applied from the AC power supply (system power supply) to the terminal portion 16 into a DC voltage, and outputs the DC voltage to the connection portion 2. Thereby, the power supply circuit 11 supplies power to the device 9 from the connection part 2. On the circuit board of the power supply circuit 11, the control unit 101 (refer to FIG. 4) is also mounted, and the details will be described later. The power supply circuit 11 may include only one circuit board, or may include a plurality of circuit boards. The casing 3 is fixed to the installation target 81 as described above. The casing 3 houses the power supply circuit 11. Strictly speaking, the casing 3 contains not only the power supply circuit 11 but also the control unit 101 and the like by accommodating the circuit board of the power supply circuit 11. Furthermore, in the case 3, in addition to the power supply circuit 11 and the control unit 101, internal components such as the connection portion 2 and the terminal portion 16 are also appropriately accommodated. The case 3 is made of synthetic resin with electrical insulation.

In this embodiment, the casing 3 is in the shape of a rectangular parallelepiped, and is formed into the same size as a wiring device of the size of three modules. The cabinet 3 has a front surface 31 exposed forward when the cabinet 3 is attached to an installation target 81. Here, the front surface 31 of the casing 3 is a rectangle whose size in the vertical direction is larger than that in the left and right direction. At least one connection port 4 is arranged on the front surface 31 of the casing 3.

This embodiment is a dual-port (dual-port) USB socket 10, so on the front 31 of the casing 3, two connection ports 4 are arranged. These two connection ports 4 are arranged side by side at a certain interval in the vertical direction. The two connection ports 4, as shown in Fig. 2A and Fig. 2B, are rectangles whose dimensions in the left-right direction are larger than those in the up-down direction when viewed from the front. That is, each connection port 4 is a horizontal (horizontal) long hole.

Inside the connection port 4, a metal shell and contacts are arranged. In this way, the connection port 4, together with the housing and contacts, etc., constitute the connection portion 2 (receptacle) for electrically and mechanically connecting the USB connector 91 of the device 9. The USB connector 91 is connected to the connecting portion 2 by inserting the USB connector 91 straight from the front to the connecting portion 2 configured in this way. That is, by inserting the plug-in USB connector 91 into the connection port 4 along the insertion direction, that is, the front-rear direction, the USB connector 91 is electrically connected to the connection portion 2 and mechanically coupled.

In the state in which the connecting portion 2 is connected to the USB connector 91, by pulling the USB connector 91 straight out from the connecting portion 2, the connection between the connecting portion 2 and the USB connector 91 is released. That is, by removing the USB connector 91 from the connection port 4 along the insertion direction (front-rear direction), the electrical connection of the USB connector 91 to the connection portion 2 is released, and the mechanical coupling is released. In short, the user can switch the connection of the device 9 (USB connector 91) to the connection portion 2 by plugging and unplugging the USB connector 91 to the connection port 4 formed on the front surface 31 of the casing 3. Not connected.

Here, in this embodiment, as shown in FIG. 3A, the housing 3 is detachably attached to the mounting frame 84 for fixing the housing 3 to the installation target 81. Further, on the mounting frame 84, the socket cover 8 is mounted as shown in FIG. 3A. Here, in this embodiment, the components of the USB socket 10 do not include the mounting frame 84 and the socket cover 8. However, the components of the USB socket 10 do not have to include the mounting frame 84 and the socket cover 8, and the components of the USB socket 10 may include at least one of the mounting frame 84 and the socket cover 8.

In the present embodiment, the USB socket 10 is a built-in type wiring appliance as described above, and therefore, it is mounted to an installation target 81 (here, a wall surface) using, for example, a mounting member 83 such as a built-in switch box. That is, a construction hole 82 is formed in the installation object 81, and the USB socket 10 is attached to the installation member 83 such as a switch box arranged on the back side (the back of the wall) of the installation object 81 through the construction hole 82.

The mounting frame 84 is, for example, a mounting frame of a large rectangular connection type wiring appliance standardized by Japanese Industrial Standards. Specifically, the mounting frame 84 is formed in a rectangular frame shape when viewed from the front. The housing 3 is mounted on the mounting frame 84 in such a way that the housing 3 is located inside the mounting frame 84.

The mounting frame 84 is made of synthetic resin as an example. In the mounting frame 84, a pair of mounting holes 841 and a pair of cover fixing holes 842 are formed. A pair of mounting screws 843 are tightened to mounting members 83 such as a switch box through a pair of mounting holes 841, so that the mounting frame 84 is mounted to the mounting target 81.

The socket cover 8 includes a makeup cover 85 and a fixed cover 86. That is, in the present embodiment, the socket cover 8 is composed of two members, the makeup cover 85 and the fixed cover 86. The socket cover 8 (the makeup cover 85 and the fixed cover 86) is made of synthetic resin as an example.

The fixed cover 86 is fixed to the mounting frame 84. The makeup cover 85 is installed on the fixed cover 86 in a manner of covering the front surface of the fixed cover 86. In this way, the makeup cover 85 is indirectly fixed to the mounting frame 84 to which the casing 3 is mounted via the fixing cover 86. A window hole 801 is formed in the makeup cover 85, and in a state where the socket cover 8 is attached to the mounting frame 84, the front surface 31 of the casing 3 is exposed from the window hole 801.

That is, the socket cover 8 is a frame-shaped member having a window hole 801, and is combined with the mounting frame 84 so that the front surface 31 of the casing 3 is exposed from the window hole 801. In other words, in a state where the mounting frame 84 and the socket cover 8 are combined, when viewed from the front, the front 31 of the casing 3 is located inside the socket cover 8 (the makeup cover 85) (inside the window hole 801) . As a result, as shown in FIG. 3B, in a state where the socket cover 8 is attached to the installation object 81 together with the casing 3, the socket cover 8 covers the periphery of the casing 3, and the mounting frame 84, construction hole 82, etc. are not exposed And make the appearance better.

More specifically, the makeup cover 85 is formed in a rectangular frame shape when viewed from the front. At the center of the makeup cover 85, a window 801 that penetrates the makeup cover 85 in the front-rear direction is formed. The makeup cover 85 is mechanically coupled with the fixed cover 86 in a detachable state by the snap-fitting structure. That is, the makeup cover 85 and the fixed cover 86 utilize the elasticity of at least one of the makeup cover 85 and the fixed cover 86 to hook the claws of one of the makeup cover 85 and the fixed cover 86 to the hole on the other. , With mechanical coupling.

In addition, the fixed cover 86 is formed in a rectangular frame shape when viewed from the front. Furthermore, a pair of through holes 861 are formed on the fixed cover 86. A pair of fixing screws 844 are locked to a pair of cover fixing holes 842 of the mounting frame 84 through a pair of through holes 861, so that the fixing cover 86 is mounted to the mounting frame 84.

(2.3) The specific composition of the USB socket Next, referring to FIG. 2A, FIG. 2B, and FIG. 4, the specific structure of the USB socket 10 of this embodiment will be described.

The USB socket 10 of this embodiment, as shown in FIG. 4, in addition to the power supply circuit 11, at least one (two here) connection portion 2, and the housing 3, further includes a terminal portion 16, a control portion 101, And the notification department 102. The control unit 101 includes a detection unit 12 and a setting unit 13. The notification unit 102 includes a display unit 14 and a sound output unit 15. At least a part of the terminal unit 16, the control unit 101, and the notification unit 102 are housed in the casing 3 together with the power supply circuit 11.

The power supply circuit 11 includes an AC/DC conversion circuit that converts AC voltage to DC voltage. The power supply circuit 11 is inserted between the terminal part 16 and the connection part 2, converts the AC voltage input from the terminal part 16 into a DC voltage, and outputs it to the connection part 2. Here, as an example, the power supply circuit 11 converts an AC voltage of 100V applied to the terminal portion 16 from an AC power supply (system power supply) into a DC voltage of 5V. Thereby, the AC voltage of 100V input to the terminal portion 16 is converted into a DC voltage of 5V by the power supply circuit 11, and a DC voltage of 5V is supplied to the connecting portion 2. In this embodiment, a plurality of (here, two) connection parts 2 are connected to one power supply circuit 11. That is, the DC voltage output from the power supply circuit 11 is applied to both the first connection portion 21 and the second connection portion 22. Thereby, the output of the power supply circuit 11 can be output from a plurality of (here, two) connection parts 2 to the USB connector 91 of the device 9.

In these configurations, the total of the currents (and power) output from the plurality of connection parts 2 to the device 9 becomes the output current of one power supply circuit 11. Therefore, for example, the rated output (current or power) of the plurality of connection parts 2 is specified by the total value of the output current (or output power) of the plurality of connection parts 2. The "rated output" mentioned in the present invention refers to the rated value of current and/or power, which is at least one of the rated current and the rated current. That is, based on the rated output (current or power) of the power supply circuit 11, the rated value of the total output (current or power) of the plurality of connection parts 2 is determined. As an example, if the rated output of the power supply circuit 11 is set to 4A, the total output current of the plurality of (here, two) connecting parts 2 is 4A, which becomes the rated value.

In this embodiment, a distribution display unit 32 is provided on the front surface 31 of the casing 3 as shown in FIG. 2A, so that the user can easily recognize the rated output as described above. In this embodiment, as an example, the distribution display portion 32 is realized by marking formed on the front surface 31 of the casing 3. The display unit 32 is allocated to display output information. The "output information" in the present invention refers to information about the amount of power that can be output by each of the connecting parts 2. For example, the rated output (current or power) of the connection part 2, that is, the rated current and rated power of the connection part 2, are related to the output power of the connection part 2, so it is included in the "output information". In FIG. 1, the illustration of the allocation display unit 32 is omitted.

Here, as shown in FIG. 2A, the distribution display portion 32 is arranged around the connection port 4 in the front surface 31 of the casing 3. In particular, in this embodiment, the distribution display portion 32 is arranged above and below the connection port 4 in the front surface 31 of the casing 3. Specifically, the output information displayed on the distribution display unit 32 represents the rated output (rated current) of each connection unit 2 like "2.5A" or "1.5A". Here, as an example, the distribution display portion 32 corresponding to the first connection portion 21 (first connection port 41) is indicated by text as output information such as "2.5A" as the rated output. The distribution display part 32 corresponding to the second connection part 22 (the second connection port 42) is indicated by text as output information such as "1.5A" of the rated output.

Furthermore, the output information displayed on the distribution display portion 32 includes priority information such as "1" or "2", which indicates the priority order of each connection portion 2. The "priority information" mentioned here can be the information indicating the priority recommended for the plurality of connection parts 2, and it is not limited to numbers such as "1" or "2". For example, it can also be used to indicate the main or Information about secondary relationships. Here, as an example, the allocation display portion 32 corresponding to the first connection portion 21 (the first connection port 41) is used as priority information, and the priority order such as "1" is indicated by a text. The distribution display portion 32 corresponding to the second connection portion 22 (the second connection port 42) has priority information such as "2" as priority information. In this example, it is recommended that the first connection part 21 be used in preference to the second connection part 22.

By displaying the output information on the distribution display section 32, it is recommended for the user to use the first connection section 21 with the highest priority. Therefore, when only one of a plurality of (here, two) connecting parts 2 is used, the user basically uses the first connecting part 21. And if the rated output of the power supply circuit 11 is 4A, when only the first connection part 21 is used, if the first connection part 21 is used within the rated value (2.5A), the two connection parts 2 The total output current is naturally within 4A. In addition, when both the first connecting portion 21 and the second connecting portion 22 are used, if the first connecting portion 21 is used within the rated value (2.5A), and the second connecting portion 22 is used within the rated value ( If used within 1.5A), the total output current of the two connection parts 2 will be within 4A.

That is, in the present embodiment, a plurality of connection parts 2 are provided. A distribution display portion 32 is provided on the front surface 31 of the casing 3, and the distribution display portion 32 displays output information about the magnitude of the power that each of the plurality of connection portions 2 can output. Furthermore, the output information includes priority information indicating the priority order of the plurality of connection parts 2. In the case of a plurality of connection parts 2, by displaying the output information (including priority information) by the distribution display part 32, it is not easy for the user to be confused as to which connection part 2 of the plurality of connection parts 2 should be used .

The terminal portion 16 is housed in the casing 3. Here, a terminal hole for connecting the wiring L1 is formed on the back of the casing 3. The terminal portion 16 is arranged in the casing 3 at a position corresponding to the terminal hole. The terminal portion 16 includes a terminal board and the like. When the tip portion (core wire) of the wiring L1 is inserted into the terminal hole, the tip portion (core wire) of the wiring L1 is mechanically held and electrically connected to the wiring L1. In this embodiment, as an example, the terminal portion 16 is a so-called quick-junction terminal of a plug-in type, and the wiring L1 can be connected only by inserting the wiring L1 from the terminal hole.

The control unit 101 includes, for example, a microcontroller having one or more processors and one or more memories as a main configuration. The microcontroller realizes the function of the control unit 101 by executing programs stored in more than one memory with one or more processors. The program can be pre-stored in the memory, can also be stored in a non-transitory storage medium such as a memory card and provided, or provided through an electrical communication line. In other words, the above-mentioned program is a program that makes one or more processors function as the control unit 101.

The control unit 101 controls at least the power supply circuit 11. In addition, in this embodiment, as described above, the control unit 101 is mounted on the circuit board of the power supply circuit 11 and is housed in the casing 3 together with the power supply circuit 11. Furthermore, the control unit 101 has functions as the detection unit 12 and the setting unit 13 as shown in FIG. 4. The detecting unit 12 compares the monitoring value with the threshold value, and detects the situation where the monitoring value exceeds the threshold value. As mentioned above, the monitoring value is determined by the magnitude of the current supplied to the device 9, the cumulative value of the current supplied to the device 9, the magnitude of the power supplied to the device 9, the amount of power supplied to the device 9, and the amount of power supplied to the device 9. At least one of the length of time constitutes. The setting unit 13 performs various settings regarding the operation of the detection unit 12, for example. The functions of the detection unit 12 and the setting unit 13 will be described in detail in the column of "(2.4) Notification Function".

The notification unit 102 notifies the detection result of the detection unit 12. In this embodiment, the notification unit 102 includes a display unit 14 and a sound output unit 15. The display unit 14 is arranged on the front of the casing 3, and reports the detection result of the detection unit 12 through its display state. In this embodiment, the display unit 14 includes a light-emitting element 141 and an optical member 142, as shown in FIG. 2B. Such display aspects of the display unit 14 include, for example, on/off, light-emitting color, or lighting mode (flashing period, etc.), or a combination thereof. In short, in this embodiment, the notification unit 102 includes the display unit 14 provided on the front surface 31 of the casing 3. The notification unit 102 reports (the detection result of the detection unit 12) based on the display state of the display unit 14.

Here, as shown in FIGS. 2A and 2B, the display portion 14 is arranged around the connection port 4 in the front surface 31 of the casing 3. In particular, in this embodiment, the display portion 14 is arranged on the front surface 31 of the casing 3 so as to surround the entire circumference of the connection port 4. Therefore, the display unit 14 emits light covering the entire circumference of the connection port 4. In other words, in the front surface 31 of the casing 3, the connection port 4 is located in the area surrounded by the ring-shaped display portion 14.

Specifically, the light emitting element 141, for example, receives power supply from the control unit 101 and emits light. The light emitting element 141 is composed of, for example, an LED (Light Emitting Diode). The optical member 142 is, for example, a molded product of a transparent resin such as acrylic resin. It is a member that guides light, that is, the output light of the light-emitting element 141 is guided to the surface (front) of the optical member 142 through the inside of the optical member 142. The optical member 142 is formed in a rectangular frame shape when viewed from the front, and its inner side becomes the connection port 4. The display portion 14 of these configurations causes the surface (front) of the optical member 142 to emit light by causing the light-emitting element 141 to emit light. That is, the surface (front surface) of the optical member 142 surrounding the connection port 4 becomes a light-emitting surface.

Furthermore, in the present embodiment, the display unit 14 is configured to be visually confirmed from the front even when the USB connector 91 of the device 9 is connected to the connection unit 2 (connection port 4). Specifically, the display unit 14 is configured such that at least a part of the display unit 14 protrudes from the periphery of the USB connector 91 when viewed from the front. That is, even if the display portion 14 is provided around the connection port 4, it is not completely shielded by the USB connector 91 inserted into the connection port 4. Thereby, even if the USB connector 91 of the device 9 is connected to the USB socket 10, the display state of the display unit 14 can be visually confirmed.

The sound output unit 15 is realized by, for example, a speaker or a buzzer. The sound output unit 15 outputs a beep sound, for example, and reports the detection result of the detection unit 12 by outputting the sound of the beep sound. The state of the beep, as an example, includes the state of "beep", "beep" or "beep-beep-". However, the sound output unit 15 is not limited to the beep sound, and may replace the beep sound with a voice or melody, or output it together with the beep sound.

In addition, in this embodiment, as described above, a plurality of connection portions 2 are provided. The notification unit 102 is configured to report the detection result to each of the plurality of connection units 2 individually. Specifically, at least the display portion 14 is provided in each connection port 4, as shown in FIGS. 2A and 2B. In other words, the display unit 14 is provided in plural corresponding to the plural connection ports 4. These plural display parts 14 are arranged around the first connection port 41 and the second connection port 42 respectively. In FIG. 4, the display unit 14 is labeled as one, but in fact, a plurality of (here, two) display units 14 are provided. The function of the notification unit 102 will be described in detail in the column of "(2.4) Notification Function".

(2.4) Notification function Next, the notification function in the USB socket 10 of this embodiment will be described. The notification function is mainly realized by the detection unit 12, the setting unit 13, and the notification unit 102 included in the control unit 101.

The detection unit 12, as described above, compares the monitoring value with the threshold value, and detects the situation where the monitoring value exceeds the threshold value (also referred to as "abnormality of the monitoring value"). The "monitoring value" mentioned in the present invention consists of the magnitude of the current supplied to the device 9, the cumulative value of the current supplied to the device 9, the magnitude of the power supplied to the device 9, the amount of power supplied to the device 9, and the amount of power supplied to the device 9 9. At least one of the lengths of time for power supply is constituted. Here, the length of time during which power is supplied to the device 9 refers to the length of the elapsed time from the start of power supply when the power is continuously supplied from the USB socket 10 (power circuit 11) to the device 9. That is, the detection unit 12 uses the magnitude of the current supplied to the device 9 from the USB socket 10 (power supply circuit 11) as a monitoring value, and compares the monitoring value with the threshold value. The threshold value is set according to each type of monitoring value, such as the threshold value for the magnitude of the current and the threshold value for the cumulative value of the current.

The magnitude of the current or power supplied by the device 9 can be detected by the magnitude of the current or power output from the power supply circuit 11, for example. Therefore, the detection unit 12, for example, monitors (measures) the current or power output from the power supply circuit 11, and detects the situation where the monitoring value exceeds the threshold value according to the magnitude of the current or power, that is, the abnormality of the monitoring value. The current output from the power supply circuit 11 can be measured by a suitable current sensor such as a converter or shunt resistor. The cumulative value of the current supplied to the device 9, the amount of power supplied to the device 9, and the length of time the power is supplied to the device 9 can all be obtained from the current or power output from the power supply circuit 11.

The monitoring value compared with the threshold is determined by the magnitude of the current supplied to the device 9, the cumulative value of the current supplied to the device 9, the magnitude of the power supplied to the device 9, the amount of power supplied to the device 9, and the amount of power supplied to the device 9. At least one of the length of the power supply time is constituted. That is, the monitoring value may be, for example, the magnitude of the current supplied to the device 9, the length of time that the power is supplied to the device 9, or a combination thereof. In this embodiment, as an example, the monitoring value is assumed to be the magnitude of the current supplied from the USB socket 10 (power circuit 11) to the device 9. That is, the detection unit 12 uses the magnitude of the current supplied from the USB socket 10 (power circuit 11) to the device 9 as a monitoring value, and compares the monitoring value with a threshold value.

The setting unit 13 performs various settings regarding the operation of the detection unit 12. The setting unit 13 sets, for example, any one of the magnitude of the current supplied to the device 9, the integrated value of the current supplied to the device 9, and the magnitude of the power supplied to the device 9, as a monitoring value. In addition, the setting unit 13 is also caused to perform settings such as a threshold value for comparison with the monitoring value. Furthermore, it is also suitable to use the setting unit 13 to perform various settings regarding the operation of the notification unit 102. In the present embodiment, as an example, the setting content of the setting unit 13 is determined based on a person's operation on the operation unit such as a two-row unit switch or a semi-fixed resistor installed in the casing 3.

Then, through the notification unit 102, the detection result of the detection unit 12 is notified. In this embodiment, as described above, the notification unit 102 includes the display unit 14 and the sound output unit 15. Therefore, the display mode of the display unit 14 or the mode of the output sound from the sound output unit 15 informs The detection result of the detection unit 12. For example, when the monitoring value is the magnitude of the current supplied from the USB socket 10 (power circuit 11) to the device 9, the notification unit 102 performs differently because the magnitude of the current (monitoring value) is below the threshold or greater than the threshold. Announcement.

As an example, if the monitored value (here, the magnitude of the current) is below the threshold value, the notification unit 102 lights the display unit 14 in green. On the other hand, if the monitored value (here, the magnitude of the current) is larger than the threshold value, that is, exceeds the threshold value, the notification unit 102 lights the display unit 14 in red. Thereby, if there is no abnormality in the monitoring value, the display part 14 is lighted in green; if there is an abnormality in the monitoring value, the display part 14 is lighted in red. Furthermore, in a state where the connection part 2 is not connected to the USB connector 91 of the device 9, the notification part 102 may also turn off the display part 14. In addition, if the monitored value (here, the magnitude of the current) is larger than the threshold value, the notification unit 102 outputs a beep sound such as "beep-beep-" from the sound output unit 15, for example. The beep should be output continuously while the monitoring value exceeds the threshold.

On the other hand, in this embodiment, a plurality of connecting portions 2 are provided as described above. Therefore, the detection unit 12 individually detects an abnormality in the monitoring value (when the monitoring value exceeds the threshold value) for each of the plurality of connection units 2. For example, when the monitoring value is the magnitude of the current supplied from the USB socket 10 (power circuit 11) to the device 9, the detection unit 12 will measure the magnitude of the current for the first connection part 21 and the second connection part 22 ( Monitoring value) exceeding the threshold value is detected as an abnormality of the monitoring value. Therefore, the detection unit 12 detects the abnormal state of the monitoring values of both the first connection portion 21 and the second connection portion 22, the state that the monitoring values of both are not abnormal, the state that only the monitoring value of the first connection portion 21 is abnormal, Or any one of the states in which only the monitoring value of the second connecting portion 22 is abnormal. In this way, in order to individually detect the abnormality of the monitored value for each of the plurality of connection parts 2, the detection part 12 distinguishes, for example, the current output from the power supply circuit 11 to the first connection part 21 and the current output from the power supply circuit 11 to the second connection. The current output by the section 22 is monitored (measured).

Then, in the present embodiment, regarding the notification unit 102, the abnormality of the monitoring value (the detection result of the detection unit 12) is also reported to each of the plurality of connection units 2 individually. For example, when the monitoring value is the magnitude of the current supplied from the USB socket 10 (power circuit 11) to the device 9, the notification unit 102 will monitor the magnitude of the current for the first connection portion 21 and the second connection portion 22 (monitoring Value) If the threshold value is exceeded, an abnormality is reported as a monitoring value. As an example, if only the monitoring value of the first connection part 21 is abnormal, the notification part 102 lights up the display part 14 corresponding to the first connection part 21 in red, and points the display part 14 corresponding to the second connection part 22. Lights up in green. In the notification unit 102, a distinction is made between the state where the monitoring values of both the first connection section 21 and the second connection section 22 are abnormal, the state where the monitoring values of both are not abnormal, the state where only the monitoring value of the first connection section 21 is abnormal, and the state only 2 If the monitoring value of the connection part 22 is abnormal, it will be notified.

(3) Operation Next, referring to FIG. 5, the operation of the USB socket 10 of this embodiment will be described. FIG. 5 is a flowchart showing an example of the operation of the USB socket 10 when the monitoring value is the magnitude of the current supplied from the USB socket 10 (power circuit 11) to the device 9.

After the USB socket 10 is turned on, the monitoring value is normal (the monitoring value is not abnormal) (S1). At this time, the notification unit 102, for example, lights the display unit 14 in green. After that, the USB socket 10 uses the detecting unit 12 to detect whether the monitored value (here, the magnitude of the current) exceeds the threshold (S2). If the detection unit 12 does not detect the abnormality of the monitoring value, that is, does not detect that the monitoring value exceeds the threshold (S2: No), the USB socket 10 continues to notify that the monitoring value is normal (S1).

If the detection unit 12 detects an abnormality in the monitoring value, that is, detects that the monitoring value exceeds the threshold (S2: Yes), the USB socket 10 reports the abnormality of the monitoring value through the notification unit 102 (S3) . At this time, the notification unit 102, for example, lights the display unit 14 in red. After that, the USB socket 10 uses the detecting unit 12 to detect whether the monitored value (here, the magnitude of the current) is below the threshold (S4). If the detection unit 12 does not detect that the monitoring value is normal, that is, it does not detect a situation where the monitoring value is below the threshold (S4: No), the USB socket 10 continues to report that the monitoring value is abnormal (S3).

If the detection unit 12 detects that the monitoring value is normal, that is, it detects that the monitoring value is below the threshold (S4: Yes), the USB socket 10 will be monitored by the notification unit 102 and the monitoring value is normal (the monitoring value is not Abnormality) notification (S1).

The USB socket 10 repeats the processes of S1 to S4 described above. The flowchart in FIG. 5 is only an example of the operation of the USB socket 10, and the processing can be omitted or added, and the sequence of the processing can be changed as appropriate.

In this way, in the USB socket 10 of the present embodiment, if the monitoring value such as the magnitude of the current supplied from the power supply circuit 11 to the device 9 exceeds the threshold value, the notification unit 102 will notify it. Therefore, for example, when an excessive current or power exceeding the rated output (current or power) of the power supply circuit 11 is supplied to the device 9 from the USB socket 10, the user can be notified of this phenomenon. In particular, the USB socket 10 is different from a general socket device that outputs AC voltage such as 100V or 200V, and there are cases where the circuit breaker of the switchboard is not directly shut off even if an overcurrent flows to the equipment 9, so such notification is a useful method. . Therefore, the abnormality of the monitoring value such as the magnitude of the current supplied by the device 9 can be notified early, and the reliability of the USB socket 10 can be improved. As a result, it is possible to provide a USB socket 10 that can easily achieve an improvement in reliability.

Furthermore, not the device 9 on the charged side, but the USB socket 10 on the charging side, that is, the side that supplies power for charging, notifies the overcurrent or the like. Therefore, the charged device may not be used for the notification of the overcurrent or the like. Power of device 9 on the side. In short, in the device 9 on the charged side, the electricity stored in the battery 92 or the electricity that should be stored in the battery 92 is not used for notification of overcurrent, etc., but can be used for the original purpose of charging. on. Therefore, according to the USB socket 10 of the present embodiment, the device 9 can be charged efficiently and so on.

(4) Modifications Embodiment 1 is only one of various embodiments of the present invention. In the first embodiment, if the purpose of the invention is achieved, various changes can be made in accordance with the design and the like. The drawings described in the present invention are schematic diagrams, and the respective ratios of the sizes and thicknesses of the constituent elements in the drawings are not limited to reflect the actual size ratios. In addition, the same functions as the USB socket 10 of the first embodiment can also be implemented by methods, (computer) programs, or non-transitory storage media storing programs, etc.

Hereinafter, a modified example of Embodiment 1 will be listed. The modified examples described below can be appropriately combined and applied. Hereinafter, with respect to the same configuration as that of the first embodiment, common symbols are given, and the description will be omitted as appropriate.

The basic structure of the USB receptacle 10 is not limited to the structure described in Embodiment 1. For example, various types of USB receptacles 10A to 10C such as those shown in FIGS. 6A to 6C can be realized.

In the aspect shown in FIG. 6A, the display portion 14 of the USB socket 10A is different from that of the first embodiment in that it is not a shape surrounding the corresponding connection port 4, but is arranged at one place around the connection port 4. Specifically, in the example of FIG. 6A, the display portion 14 is a point light source arranged above the corresponding connection port 4.

In the aspect shown in FIG. 6B, the USB socket 10B has the casing 3 formed into the same size as the wiring device of the size of the two modules. The USB socket 10B, for example, together with the socket device 51 that outputs an AC voltage of 100V, is mounted on the installation target 81 (refer to FIG. 3A) by the mounting frame 84 (refer to FIG. 3A).

In the aspect shown in FIG. 6C, the USB socket 10C is a single port (single port) that has the housing 3 formed into the same size as the wiring appliances of the two module sizes, and can be connected to a USB connector 91 Type of USB socket. In the example of FIG. 6C, the connection port 4 is a rectangle with a size larger in the vertical direction than the size in the left and right direction when viewed from the front. That is, the connection port 4 is arranged in a longitudinal direction (straight type). Furthermore, the USB socket 10C, for example, is mounted on the installation target 81 (refer to FIG. 3A) by the mounting frame 84 (refer to FIG. 3A) together with the sensor device 52 such as a human body sensor. The sensor device 52 is not limited to a human body sensor. For example, it may be a brightness sensor, a vibration sensor, a proximity sensor, or a sound sensor, or a combination thereof. The USB socket 10C can also operate according to the output of the sensor device 52. For example, in the case where the sensor device 52 is a human body sensor, the USB socket 10C, if there is no one around, the power to the connection part 2 will be turned off.

In addition, in the USB socket, there may be one connection portion 2 (connection port 4), or three or more.

In addition, the plurality of connection parts 2 may include two or more connection parts 2 of different generations (standards of transmission speed) and/or USB terminal shapes. For example, the USB receptacle 10 may include the connection part 2 of the A terminal (USB Type-A) and the connection part 2 of the C terminal (USB Type-C).

The USB socket 10 of the present invention includes a computer system in the control unit 101 and the like. Computer systems are mainly composed of processors and memory as hardware. The function of the USB socket 10 of the present invention is realized by making the processor execute the program stored in the memory of the computer system. Programs can be pre-stored in the memory of the computer system, can also be provided through electrical communication lines, or can be stored in non-transitory storage media such as memory cards, optical disks, and hard disks that can be read by the computer system. . The processor of a computer system is composed of one or more electronic circuits including semiconductor integrated circuits (IC) or large integrated circuits (LSI). Integrated circuits such as IC or LSI mentioned here are called differently depending on the degree of concentration, including system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale) Integration, very large integrated circuit) of the integrated circuit. Furthermore, FPGA (Field-Programmable Gate Array) can be programmed after the manufacture of the LSI, or it can be used to reconstruct the bonding relationship within the LSI or to re-separate the circuit within the LSI. The logical components of the composition are used as processors. Multiple electronic circuits can be integrated into one chip or distributed on multiple chips. Multiple chips can be integrated into one device or distributed in multiple devices. The computer system described here includes a microcontroller with more than one processor and more than one memory. Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

In addition, integrating at least a part of the functions of the USB socket 10 into one casing 3 is not a necessary component of the USB socket 10, and the components of the USB socket 10 may also be distributed in a plurality of casings. For example, a part of the functions of the control unit 101 may be provided in a casing different from the connection unit 2 (connection port 4). In addition, at least a part of the functions of the control unit 101 and the like, for example, may also be realized by a server or cloud (cloud computing).

In addition, the USB socket 10 is not limited to indoor use, but may also be used outdoors. In the USB socket 10 for outdoor use, a rain-proof (drip-proof) structure is appropriately adopted.

In addition, in the first embodiment, although the case where the device 9 connected to the USB socket 10 is a rechargeable device 9 is described as an example, it is not limited to this example, and a non-chargeable device 9 can also be connected to the USB socket 10 (Equipment 9 other than rechargeable equipment 9).

In addition, the USB socket 10, for example, may also have a function of judging whether the device 9 connected to the USB socket 10 is a rechargeable device. These discrimination functions, as an example, are realized by the following method: the USB socket 10 communicates with the device 9 through wired communication or wireless communication through the USB connector 91. If it has such a discrimination function, the USB socket 10, for example, may only be connected to a rechargeable device 9 by the detection unit 12 to detect that the monitoring value exceeds the threshold value (abnormality of the monitoring value).

In addition, the USB socket 10 is not limited to a built-in wiring appliance. That is, the USB socket 10 may be an "exposure type" wiring tool, and it may be arranged so that the entirety is exposed from the surface of the installation object 81 such as a wall surface. In this case, the USB socket 10 is installed to the installation object 81 by using an exposed switch box instead of an embedded switch box. In addition, the USB socket 10 may be attached to the attachment object 81 by using attachment members other than the switch box, such as a clip.

In addition, mounting the housing 3 to the mounting frame 84 is not a necessary configuration of the USB socket 10. For example, the housing 3 and the mounting frame 84 may be integrated. Furthermore, mounting the socket cover 8 to the mounting frame 84 is not a necessary component of the USB socket 10, and the socket cover 8 may be omitted as appropriate.

The USB socket 10, for example, may also be provided by devices such as a personal computer.

In addition, in Embodiment 1, although a plurality of connection parts 2 are connected to one power supply circuit 11, this configuration is not an essential configuration of the USB socket 10, and individual power supply circuits 11 may be provided for each of the plurality of connection parts 2. That is, the USB socket 10 may include a plurality of connection portions 2 and a plurality of power supply circuits 11 corresponding to the plurality of connection portions 2 one-to-one. In this case, power is supplied from individual power supply circuits 11 to the plurality of connection parts 2, so the rated output (current or electric power) is also specified for each connection part 2 individually.

In addition, the distribution display portion 32 is not limited to the marking formed on the front surface 31 of the casing 3, and may be realized by printing, a label, a display lamp (light emitting element), or a display, for example. When the distribution display unit 32 is realized by a display lamp, a display, or the like, the display content of the distribution display unit 32 can be appropriately changed.

In addition, the distribution display section 32 is not a necessary configuration of the USB socket 10, and the distribution display section 32 may be omitted as appropriate.

In addition, the detection unit 12 is used to detect the situation where the monitoring value exceeds the threshold (abnormality of the monitoring value), and is not limited to monitoring (measurement) the current output from the power circuit 11, for example, it may also be monitored (measurement). Power output from the power supply circuit 11. Furthermore, the detection unit 12 can also detect the situation where the monitoring value exceeds the threshold value (abnormality of the monitoring value) by means other than monitoring (measurement) of the output (current or power) of the power supply circuit 11. For example, the detection unit 12 can also communicate with the device 9 connected to the connection unit 2 through wired communication or wireless communication via the USB connector 91. In this case, the detection unit 12 can detect a situation in which the monitoring value exceeds the threshold value (abnormality of the monitoring value) through communication with the device 9.

In addition, the detection unit 12 individually detects that the monitoring value exceeds the threshold value (abnormality of the monitoring value) for each of the plurality of connection units 2, and is not a necessary configuration of the USB socket 10. That is, the detection unit 12 may also detect a situation in which the monitoring value exceeds the threshold value (abnormality of the monitoring value) for a plurality of connection units 2 together. Similarly, the notification unit 102 individually reports that the monitoring value exceeds the threshold value (abnormality of the monitoring value) for each of the plurality of connection units 2, and is not a necessary configuration of the USB socket 10. That is, the notification unit 102 may collectively notify a situation in which the monitoring value exceeds the threshold value (abnormality of the monitoring value) to the plurality of connection units 2.

In addition, when the monitoring value exceeds the threshold value, the notification unit 102 may be required to notify, and the detection unit 12 is not a necessary configuration of the USB socket 10. That is, by replacing the detection unit 12, the notification unit 102 compares the monitoring value with the threshold value to detect the situation where the monitoring value exceeds the threshold value, and the detection unit 12 can be omitted as appropriate.

Furthermore, the notification unit 102 may also notify (notify) the monitored value itself (for example, the magnitude of the current). For example, when the monitoring value exceeds the threshold value, the notification unit 102 may notify the monitoring value itself through display or voice output. In addition, even if the monitoring value does not exceed the threshold value, the notification unit 102 may notify the monitoring value itself through display or voice output at an arbitrary timing (for example, periodically).

In addition, the notification unit 102 is provided with the display unit 14 and the audio output unit 15 and is not an essential component of the USB socket 10. The notification unit 102 may not have either the display unit 14 or the audio output unit 15.

In addition, providing the display unit 14 with the light emitting element 141 and the optical member 142 is not a necessary configuration of the USB socket 10. The display unit 14 may also be realized by an image display device such as a liquid crystal display or an organic EL (Electro Luminescence) display.

(Embodiment 2) The USB socket 10D of this embodiment is different from the USB socket 10 of the first embodiment in that it has the function of communicating with the communication terminal 62 as shown in FIG. 7. Hereinafter, with respect to the same configuration as that of the first embodiment, common symbols are given, and the description will be omitted as appropriate.

That is, the USB socket 10D of this embodiment includes a communication unit 61. The communication unit 61 is configured to be able to communicate with the communication terminal 62. The "communicable" mentioned in the present invention refers to information that can be transmitted and received directly, or indirectly via a network or a repeater, through an appropriate communication method such as wired communication or wireless communication. In this embodiment, the communication unit 61 and the communication terminal 62 can perform bidirectional communication via a network, for example. In this embodiment, as an example, the communication unit 61 adopts a general model based on specifications such as Wi-Fi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or low-power radio (specific low-power radio) that does not require a license. Wireless communication using radio waves as a communication medium.

The communication terminal 62 is a terminal having at least the function of communicating with the communication unit 61, such as a portable terminal such as a smart phone, a tablet terminal, or a wearable terminal, or a personal computer. This kind of communication terminal 62 has a user interface such as a display function and a sound output function. In the example of FIG. 7, the communication terminal 62 is a tablet terminal which is different from the device 9 connected to the USB socket 10D. However, the communication terminal 62 may also be the device 9 connected to the USB socket 10D.

Here, the notification unit 102 has a function of using the communication unit 61 to send the detection result of the detection unit 12 to the communication terminal 62. That is, the detection result of the detection unit 12 is transmitted from the communication unit 61 to the communication terminal 62. Specifically, if the monitoring value exceeds the threshold value, the notification unit 102 sends the detection result of the detection unit 12 indicating that the monitoring value exceeds the threshold value from the communication unit 61 to the communication terminal 62 as a notification instruction. The communication terminal 62 that has received the detection result of the detection unit 12 can directly display the detection result of the detection unit 12, or it can only perform push notifications when there is a specific operation performed by the user (operation of a specific object) ) And the detection result of the detection part 12 is displayed.

In this manner, in the present embodiment, the notification unit 102 sends a notification instruction to the communication terminal 62 through communication if the monitoring value exceeds the threshold value to notify. In this way, for example, even when the USB socket 10D is located at a blind spot of the user, or is located far away from the user, the user can easily confirm the detection result of the detection unit 12 through the communication terminal 62.

In addition, as in the present embodiment, when two-way communication is possible between the communication unit 61 and the communication terminal 62, the notification unit 102 may also use the detection result of the detection unit 12 as a countermeasure from the communication terminal 62 The response to the outgoing signal is sent to the communication terminal 62. That is, when the communication unit 61 receives the outgoing signal from the communication terminal 62, the notification unit 102 transmits the detection result of the detection unit 12 to the communication terminal 62 through communication. Thereby, when the user wants to confirm the state of the monitoring value (whether the monitoring value exceeds the threshold value), the communication terminal 62 can confirm the state of the monitoring value.

Furthermore, in the USB socket 10D of this embodiment, the communication with the communication terminal 62 is wireless communication or power line communication. That is, the communication unit 61 communicates with the communication terminal 62 through wireless communication using radio waves as a medium, or power line communication using power lines as a medium. In this case, it is not necessary to connect a dedicated communication line to the USB socket 10D. That is, it is not necessary to connect in the case of wireless communication, and it is not necessary to connect a dedicated communication line to the USB socket 10D in the case of power line communication. That is, the wiring L1 connected to the terminal portion 16 is a power line, so the communication section 61 can perform power line communication with the communication terminal 62 by using this wiring L1 as a transmission line. In addition, the communication unit 61 can also use both wireless communication and power line communication to communicate with the communication terminal 62.

The configuration (including modification examples) described in Embodiment 2 can be appropriately combined with the various configurations (including modification examples) described in Embodiment 1.

(Embodiment 3) As shown in FIG. 8, the USB socket 10E of this embodiment is different from the USB socket 10 of the first embodiment in that it includes a limiting circuit 17. Hereinafter, with respect to the same configuration as that of the first embodiment, common symbols are given, and the description will be omitted as appropriate.

The limiting circuit 17 limits the power supplied to the device 9 from the USB socket 10E (power circuit 11) when the monitored value exceeds the first threshold or the second threshold. The "first threshold" mentioned here is the threshold used in the notification judgment of the notification unit 102. In addition, the "second threshold" mentioned here is a threshold different from the first threshold. The second threshold value may be a value larger than the first threshold value, or may be a value smaller than the first threshold value. In this embodiment, as an example, the second threshold value is a value larger than the first threshold value; the limiting circuit 17 limits the power supplied from the power supply circuit 11 to the device 9 if the monitoring value exceeds the second threshold value.

That is, in the USB socket 10E of the present embodiment, if the monitoring value exceeds the first threshold value, the notification unit 102 is caused to report. In addition, if the monitoring value of the USB socket 10E exceeds the second threshold value (>the first threshold value), the limit circuit 17 limits the power supplied from the power supply circuit 11 to the device 9. The "restriction of power" in the present invention includes power reduction and power isolation (stop power supply). In this embodiment, the restriction circuit 17 restricts the electric power by reducing the electric power supplied from the power supply circuit 11 to the device 9.

As an example, the limiting circuit 17 controls the switching elements included in the power supply circuit 11 to reduce the output current of the power supply circuit 11 and reduce the power output from the power supply circuit 11 to the device 9. In addition, the limiting circuit 17, as an example, can also reduce the output current from the power supply circuit 11 to the connection portion 2 by drawing a part of the current output from the power supply circuit 11, thereby reducing the power output from the power supply circuit 11 to the device 9 . The limiting circuit 17 reduces the current supplied from the power supply circuit 11 to the device 9 to below the first threshold value, for example, if the monitored value (here, the magnitude of the current) exceeds the second threshold value.

In this manner, the USB socket 10E of the present embodiment includes the limiting circuit 17, and if the monitoring value exceeds the threshold value or a second threshold value different from the threshold value, which is the first threshold value, the power supplied to the device 9 is limited. Thereby, for example, the pressure on the power supply circuit 11 and the device 9 caused by the supply of overcurrent from the power supply circuit 11 to the device 9 can be reduced. The limiting circuit 17 is not limited to the configuration that limits the electric power when the monitoring value exceeds the second threshold value as described above, and may limit the electric power when the monitoring value exceeds the first threshold value (threshold value).

As a modification of the third embodiment, the second threshold value may be a value smaller than the first threshold value.

The configuration (including modification examples) described in Embodiment 3 can be appropriately combined with the various configurations (including modification examples) described in Embodiment 1 or 2 as appropriate.
