(Embodiment 1)

(1) Summary

The outlet system 10 of this embodiment includes an outlet 1 as shown in FIG. 1A. The outlet 1 (Concent, Outlet) includes a terminal member 2, a connecting member 3, and a housing 4 (refer to FIG. 2A). In this embodiment, all the components (terminal member 2 and connection member 3, etc.) other than the housing 4 of the outlet system 10 are housed or held in the housing 4. That is, in this embodiment, all the components of the outlet system 10 are integrated in one outlet 1, and the outlet system 10 is the same as the outlet 1.

The outlet 1 (outlet system 10) of this embodiment is, for example, a wiring appliance that is connected to a plug 91 (refer to FIG. 5A) of an electrical appliance to supply power to the electrical appliance, that is, an outlet. The socket 1 is installed, for example, in a residential facility such as a single-family house or a collective housing, or in a non-residential facility such as an office, a store, a school, or a care facility. The socket 1 is, for example, installed on a construction surface 100 such as a wall surface, a ceiling surface, and a floor surface of a facility (building) (refer to FIG. 2A).

The socket system 10 of the present embodiment, as shown in FIGS. 1A and 1B, in addition to the terminal member 2, the connecting member 3 and the housing 4, further includes a temperature detection unit 5, an opening/closing unit 6 and a heat transfer structure 50. The terminal member 2 is a member connected to the power supply line 92 (refer to FIG. 5B). The connecting member 3 is a member connected to the plug 91. The housing 4 houses the terminal member 2 and the connecting member 3.

The temperature detection unit 5 includes a temperature sensor 51. The temperature detection unit 5 uses one temperature sensor 51 to detect the temperature of the detection point group P100 as the detection temperature. The detection point group P100 includes at least one of a plurality of first detection points and a plurality of second detection points. The first detection points are plural detection points that are electrically insulated from each other. The plural second detection points are plural detection points provided at different locations in the internal space 40 (refer to FIG. 1B) of the terminal member 2, the connecting member 3, and the housing 4. As an example, the combination of the detection point P1 and the detection point P2 in FIG. 1B (or the combination of the detection point P3 and the detection point P4) becomes the first detection point. The details will be described later. On the other hand, the combination of the detection point P1, the detection point P3, and the detection point P5 in FIG. 1B (or the combination of the detection point P2, the detection point P4, and the detection point P5) becomes a plurality of second detection points.

Here, the detection point group P100 that becomes the temperature detection target of one temperature sensor 51 may include at least one of a plurality of first detection points and a plurality of second detection points. That is, the detection point group P100 may include only the plurality of first detection points among the plurality of first detection points and the plurality of second detection points, may only include the plurality of second detection points, or may include the plurality of first detection points and plural Both sides of the second detection point. P100 contains plural numbers in the detection point group In the case of both the first detection point and the plural second detection points, a part of the first detection point may overlap with a part of the second detection point. That is, in the example of FIG. 1B, the detection point P1 becomes the first detection point in combination with the detection point P2, and becomes the second detection point in the combination with the detection point P3 and the detection point P5. In this way, a part of the first detection point may be the same detection point as a part of the second detection point (for example, the detection point P1).

The opening and closing portion 6 is electrically connected between the terminal member 2 and the connecting member 3. The opening and closing section 6 switches from the on state to the off state when the determination condition is satisfied. The judgment condition includes that the detected temperature is higher than the threshold temperature. The heat transfer structure 50 thermally couples the detection point group P100 and one temperature sensor 51. The "thermal coupling" disclosed in the present invention refers to coupling between two points by means of heat (thermal energy) moving between two points by heat conduction, radiation, or convection, or a combination thereof. That is, heat can move between the detection point group P100 thermally coupled by the heat transfer structure 50 and one temperature sensor 51.

According to the above configuration, in the outlet system 10, if the detection temperature of the temperature detection unit 5 becomes higher than the threshold temperature and the determination condition is satisfied, the opening and closing unit 6 is switched from the conducting state to the blocking state, thereby electrically connecting the terminal member 2 and the connecting member 3 cut off. Therefore, the socket system 10 can automatically connect the connection member 3 and the terminal member if the detected temperature rises due to poor contact between the terminal member 2 and the power supply line 92, or poor contact between the connection member 3 and the plug 91, etc. 2 Electrically cut off. In this way, for example, even in a state where the connecting member 3 is connected to the plug 91 of the electric appliance, the power supply to the electric appliance can be stopped, and further heat generation can be suppressed.

In addition, in the above-mentioned outlet system 10, the temperature detection unit 5 detects the temperature of the detection point group P100 as the detection temperature through one temperature sensor 51, and the detection point group P100 includes a plurality of first detection points and a plurality of first detection points. 2 At least one of the detection points. That is, in the outlet system 10, one temperature sensor 51 is used to detect one of a plurality of first detection points that are electrically insulated from each other, and a plurality of second detection points that are provided at different locations. The temperature of at least one. Therefore, one temperature sensor 51 is shared for temperature detection at a plurality of first detection points, for example. In addition, one temperature sensor 51 is shared for temperature detection at a plurality of second detection points, for example. Therefore, compared to the case where individual temperature sensors are provided at the first detection points, or the case where individual temperature sensors are provided at the second detection points, one of the required temperature sensors can be used. The number is suppressed to a small amount. As a result, according to the socket system 10 described above, the number of temperature sensors required for the number of detection points can be suppressed to a small amount, and an increase in the number of parts can be suppressed.

(2) Details

Next, the outlet system 10 of this embodiment will be described in more detail.

(2.1) Overall composition

First, referring to FIGS. 1A to 4B, the overall configuration of the outlet system 10 will be described.

The socket system 10 of this embodiment, as shown in FIG. 1A, includes a terminal member 2, a connecting member 3, a housing 4 (refer to FIG. 2A), a temperature detection unit 5, and an opening/closing unit 6, and further includes a control unit 7, an operating unit The member 81, the display 82, the buzzer 83, and the switch 84. In addition, the socket system 10, as shown in FIG. 1B, includes a heat transfer structure 50, and the heat transfer structure 50 thermally couples the detection point group P100 and one temperature sensor 51.

2A and 2B are perspective views of the state in which the socket 1 of the socket system 10 is installed on the construction surface 100. In this embodiment, the socket 1 is a built-in wiring appliance installed in the mounting frame of a large rectangular connecting wiring appliance standardized in accordance with Japanese Industrial Standards. Specifically, the socket 1 is mounted on the construction surface 100 via the mounting frame. Here, the installation frame is fixed to the construction surface 100 via an insert box or directly. That is, by fixing the installation frame to the construction surface 100, the socket 1 is installed on the construction surface 100 through the installation frame. Install the makeup cover 101 on the mounting frame, as shown in Figures 2A and 2B, the socket 1 is exposed from the inside of the makeup cover 101 state. Here, the mounting frame may be a different component from the housing 4 of the socket 1, or may be integrated with the housing 4. In this embodiment, the case where the socket 1 is used indoors, that is, the case where the construction surface 100 is the inner wall surface of a building (facility) is described, but it is not limited to this example, and the socket 1 may also be used outdoors.

Hereinafter, the direction perpendicular to the horizontal plane (orthogonal) when the socket 1 is installed on the construction surface 100, that is, the inner wall of the building, is described as the "up and down direction"; when viewed from the front, the bottom of the socket 1 (vertical direction) As "below" description. In addition, the direction perpendicular to the vertical direction and parallel to the construction surface 100 is described as the "left-right direction"; when viewed from the front, the right side of the socket 1 is described as "right", and the left side is described as "left". Furthermore, the direction perpendicular to both the up-down direction and the left-right direction, that is, the direction perpendicular to the construction surface 100, is described as the "front-rear direction"; and the back side (wall back side) of the construction surface 100 is described as the "rear". However, these directions are not intended to limit the usage direction of the socket system 10. For example, when the socket 1 is installed on the floor surface instead of the wall surface, the "front-rear direction" becomes the direction perpendicular to the horizontal plane, and the "up-down direction" and the "left-right direction" become directions parallel to the horizontal plane. In addition, when the socket 1 is installed on a wall surface, the "up and down direction" is also a direction parallel to the horizontal plane (ie, lateral direction). The socket 1 is installed on the wall surface so that the "left-right direction" becomes a direction perpendicular to the horizontal plane.

In addition, in this embodiment, as the socket system 10, a double-port socket 1 capable of connecting two plugs 91 at the same time is exemplified. That is, the socket 1 has two connection ports 11 corresponding to the two plugs 91. The two connection ports 11 are configured to be connectable to one plug 91 respectively, and are arranged side by side in the vertical direction (vertical direction) on the front surface of the housing 4. One of the two connection ports 11 (upper) is a two-pole socket with no grounding pole for AC 100V; the other (lower) connection port 11 is a two-pole socket with grounding pole for AC 100V. Pole socket.

In this embodiment, the socket 1 is provided with a pair of terminal members 2 having opposite polarities to each other, which corresponds to a two-pole plug 91. That is, one of the terminal members 2 of the pair of terminal members 2 is connected to the power supply line 92 on the L pole (HOT) side; the other terminal member 2 is connected to the power supply line 92 on the N pole (COLD) side. Similarly, the socket 1 is provided with a pair of connecting members 3 having different polarities in each connection port 11, and a total of two pairs (4) of connecting members 3 are provided. Here, two connecting members 3 of the same polarity are connected by a lead plate 30 (refer to FIG. 3). Furthermore, the connecting member 3 and the terminal member 2 which have the same polarity to each other are electrically connected via the opening and closing portion 6.

The socket 1 includes a housing 4 and internal components such as a terminal member 2 and a connecting member 3 housed or held in the housing 4. As shown in FIG. 3, the housing 4 includes an outer shell 41, an outer cover 42, an inner shell cover 43, an inner partition 44, and a terminal partition 45. The housing 4 is formed by combining the outer shell 41, the outer shell cover 42, the inner shell cover 43, the inner spacer 44, and the terminal spacer 45. The case 4 is made of synthetic resin with electrical insulation.

The outer shell 41 is formed in a box shape with an open front surface. The opening surface (front surface) of the outer shell 41 is a rectangle whose vertical dimension is longer than the horizontal dimension. The internal partition 44 maintains the state of the connection member 3, and is housed in the outer casing 41 together with other internal parts (the terminal member 2 and the opening and closing portion 6, etc.). An inner shell cover 43 is installed on the front surface of the outer shell 41. As a result, between the outer shell 41 and the inner shell cover 43, internal parts including the connecting member 3 held in the internal partition 44 are housed. The outer shell cover 42 is installed on the front surface of the inner shell cover 43. Thereby, the connecting member 3 is accommodated between the internal partition 44 and the outer cover 42. Here, an opening window 431 penetrating in the front-rear direction is formed in a portion of the inner case cover 43 corresponding to the inner partition 44. Therefore, the front surface of the internal partition 44 holding the connection member 3 is covered with the housing cover 42. When the housing cover 42 is removed, the front surface of the internal partition 44 is exposed forward through the opening window 431. The terminal spacer 45 holds the terminal member 2 and is housed in the housing 41 together with other internal parts.

That is, the inner partition 44 and the outer cover 42 constitute a holding member for holding the connecting member 3. The terminal spacer 45 constitutes a holding member for holding the terminal member 2. In other words, the socket system 10 further includes a holding member that holds at least one of the terminal member 2 and the connecting member 3.

In this embodiment, the housing cover 42 is configured to be further divided into a plurality of members (for example, three members), but the housing cover 42 may be integrated (one member). Here, the part of the housing cover 42 that covers the internal partition 44 and the internal partition 44 are made of urea resin, for example.

In the part of the housing cover 42 that covers the internal partition 44, the above-mentioned two connection ports 11 are formed. One (upper) connection port 11 of the two connection ports 11 is provided with a pair of plug blades 911 ( Refer to the pair of insertion holes 111 in Fig. 5A). The other (lower) connection port 11 of the two connection ports 11 has a pair of insertion holes 111, and the ground pin of the plug with a grounding electrode is inserted into the ground Insert hole 112, and ground cover 113. Inside the housing 4, the connecting member 3 is arranged at a position corresponding to each insertion hole 111, the first ground member 114 is arranged at a position corresponding to the ground insertion hole 112, and the second ground member 114 is arranged at a position corresponding to the ground cover 113. Component 115. The first ground member 114 is a spring member connected to the ground pin of a plug with a ground electrode. The second ground member 115 is a screw terminal connected to the ground wire of the electrical appliance. The ground wire can be attached to and detached from the second ground member 115 when the ground cover 113 is opened.

In addition, in the space between the outer casing 41 and the inner casing cover 43, the opening and closing portion 6 and the base plate 85 are housed on the left of the inner partition 44. The substrate 85 is arranged above the opening and closing portion 6. On the substrate 85, the first indicator lamp 821 and the second indicator lamp 822 constituting the display portion 82, and the switch 84 are mounted. As an example, the first indicator lamp 821 and the second indicator lamp 822 are LEDs (Light Emitting Diodes) with different luminous colors; the switch 84 is a push button switch. In this manner, the opening and closing portion 6, the display portion 82, and the switch 84 are housed in the housing 4 (the outer shell 41 and the inner cover 43). However, the light-transmitting portion 432 and the cantilever piece 433 are formed in the inner shell cover 43, which may The light of the display unit 82 is visually confirmed from the front of the casing 4, and the switch 84 can be pressed from the front of the casing 4. That is, the light of the display portion 82 can be visually confirmed from the front of the housing 4 through the light transmitting portion 432, and the switch 84 can be pressed and operated from the front of the housing 4 through the cantilever piece 433. In FIGS. 2A and 2B, for convenience, the positions corresponding to the display portion 82 (the first display lamp 821 and the second display lamp 822) and the switch 84 on the front surface of the housing 4 are given to the display portion 82 and the switch 84 symbol.

The control unit 7 is housed in the housing 4, and is mounted on a control board arranged behind the internal shelf 44, for example. The buzzer 83 is also housed in the housing 4 in the same manner, and is mounted on a control board, for example. The control unit 7 is electrically connected to the opening and closing unit 6, the display unit 82, the buzzer 83, the switch 84, and the temperature detection unit 5. The control unit 7 controls at least the opening and closing unit 6, the display unit 82, and the buzzer 83.

The control unit 7 has, for example, a microcomputer as a main configuration. The microcomputer realizes the function of the control unit 7 by executing a program recorded in the memory of the microcomputer with a CPU (Central Processing Unit). The program can be pre-recorded in the memory of the microcomputer, and can also be provided by recording on a non-temporary recording medium such as a memory card, or through a telecommunication line. In other words, the above-mentioned program is a program that makes the microcomputer function as the control unit 7.

In addition, the control unit 7 has a function as a notification unit 71 and a function as a status presentation unit 72. The notification unit 71 notifies when the warning determination condition is satisfied, and the warning determination condition includes that the temperature detected by the temperature detection unit 5 is higher than the warning temperature lower than the threshold temperature. In this embodiment, as an example, the notification by the notification unit 71 is realized by the output of the reminder sound from the buzzer 83 and the reminder display on the display unit 82. That is, the control unit 7 realizes the notification from the notification unit 71 by controlling the buzzer 83 and the display unit 82. The state prompting section 72 prompts that the opening and closing section 6 is in a conducting state or in a blocking state. In the present embodiment, as an example, the notification of the state notification unit 72 is based on the output of the warning sound from the buzzer 83, And the warning display on the display part 82 is realized. That is, the control unit 7 controls the buzzer 83 and the display unit 82 to realize the notification of the status notification unit 72. The details of the control unit 7 (including the notification unit 71 and the status presentation unit 72) will be described in the paragraph "(2.3) Operation".

The switch 84 is operated when the sound output of the buzzer 83 is stopped. That is, if the switch 84 is pressed while the buzzer 83 is outputting a reminder sound or a warning sound, the control unit 7 controls the buzzer 83 to stop the buzzer 83. In addition, the switch 84 is also used as a test switch, and is also used when the opening and closing portion 6 is forcibly switched from the on state to the off state.

The opening and closing portion 6 is electrically connected between the terminal member 2 and the connecting member 3. The opening and closing section 6 is a device that switches between the on state and the off state. That is, if the opening and closing portion 6 is in a conductive state, the terminal member 2 and the connecting member 3 are conducted through the opening and closing portion 6; if the opening and closing portion 6 is in a disconnected state, the terminal member 2 and the connecting member 3 are opened and closed by Section 6 is electrically isolated (insulated). In the present embodiment, as described above, the socket 1 includes a pair of terminal members 2 that have mutually different polarities; and the opening and closing portion 6 electrically connects both of the pair of terminal members 2. Therefore, if the opening/closing portion 6 is in a blocked state, the two pairs (4) of the connection members 3 are all electrically disconnected from the terminal member 2.

Specifically, the opening/closing section 6 includes a butting device which has mutually different polarities and an electromagnetic release device. A pair of contact devices each have a fixed contact and a movable contact. The movable contact moves between the closed position in contact with the fixed contact and the open position away from the fixed contact. The fixed contact is electrically connected to the terminal member 2, and the movable contact is electrically connected to the connecting member 3. In more detail, the movable contact is disposed on the movable contact, and the movable contact is connected to the lead plate 30 with a braided wire, so that the movable contact is electrically connected to the connecting member 3.

The opening/closing portion 6 of such a structure is in a conductive state to conduct conduction between the terminal member 2 and the connecting member 3 by placing the movable contact in the closed position in the stable state. On the other hand, when the opening and closing section 6 receives the drive signal from the control section 7, the electromagnetic release device is activated to drive the movable contact, and the movable contact is moved to the open position, thereby switching between the terminal member 2 and the connecting member 3. The state of electrical isolation between. In this way, the opening and closing section 6 is switched from the on state to the off state by the drive signal from the control section 7.

In addition, the opening and closing portion 6 is mechanically coupled to the operating member 81. The operating member 81 is a lever-type handle that can rotate around a rotating shaft. Here, a first operation hole 434 and a second operation hole 421 are formed in the inner case cover 43 and the outer case cover 42, respectively, so that the operation member 81 can be operated from the front of the housing 4. That is, the operating member 81 is exposed to the front of the housing 4 through the first operating hole 434 and the second operating hole 421, and is operable from the front of the housing 4.

The operating member 81 rotates in conjunction with the opening and closing portion 6 and moves between an ON position (refer to FIG. 2A) and an OFF position (refer to FIG. 2B). The open position is a position corresponding to the conductive state of the opening and closing portion 6, and the closed position is a position corresponding to the blocking state of the opening and closing portion 6. That is, if the opening and closing portion 6 is in a conductive state, as shown in FIG. 2A, the operating member 81 is located at the open position. When the operating member 81 is in the open position, the front surface of the operating member 81 and the front surface of the housing 4 are substantially the same surface. On the other hand, when the opening and closing portion 6 is switched from the conducting state to the blocking state, the operating member 81 rotates, and the front end of the operating member 81 moves forward (the approaching front side). As shown in FIG. 2B, the operating member 81 moves to the closed position mobile. When the operating member 81 is in the closed position, the operating member 81 protrudes forward from the front surface of the housing 4.

In this way, the operating member 81 is interlocked with the opening and closing portion 6, so if the opening and closing portion 6 receives the drive signal from the control portion 7, and the opening and closing portion 6 is switched from the conducting state to the blocking state, the operating member 81 moves from the open position to the closed position 置Mobile. Conversely, when the operating member 81 moves from the closed position to the open position, the opening and closing portion 6 is switched from the blocking state to the conducting state. Therefore, the user operates the operating member 81 at the closed position to move to the open position, whereby the opening and closing portion 6 in the blocking state can be switched to the conducting state. Hereinafter, the operation of moving the operating member 81 from the closed position to the open position is referred to as "recovery operation". The details of the recovery operation will be explained in the paragraph "(2.3) Operation".

In addition, in the present embodiment, the opening and closing section 6 not only switches from the on state to the off state when the operating member 81 is moved from the open position to the closed position when the drive signal from the control section 7 is received. Therefore, the conducting state and the blocking state of the opening and closing portion 6 can be manually switched by the user by the operation of the operating member 81. In other words, the opening and closing portion 6 functions as a switch device that is turned ON/OFF in response to the operation of the operating member 81.

Next, referring to FIGS. 4A to 5B, the configuration of the connecting member 3 and the terminal member 2 will be described.

Two pairs (4 pieces) of connecting members 3, as shown in FIG. 4A and FIG. 5A, are held in the internal partition 44. Here, the two pairs of connecting members 3 are arranged at positions corresponding to the two pairs of insertion holes 111 formed in the housing cover 42, specifically, in the four corners of the inner frame 44 in the front view. Furthermore, as described above, the two connecting members 3 having the same polarity, that is, the two connecting members 3 arranged in the vertical direction, are connected by the lead plate 30. The pair of lead plates 30 that have mutually different polarities is formed in a long plate shape that is longer in the vertical direction than in the horizontal direction. Here, the two connecting members 3 and the lead plate 30 having the same polarity are integrally formed by a single metal plate. In FIGS. 4A and 5A, the metal plates constituting the connecting member 3 and the lead plate 30 are given dots (dotted hatching).

Each connecting member 3 is an edge-receiving member into which the bolt blade 911 of the plug 91 is inserted when the plug 91 is connected. Each connection member 3 is made of a metal having conductivity and elasticity, such as copper or copper alloy. Each connecting member 3 includes a pair of key blade receiving pieces 31 facing each other in the left-right direction. Each connecting member 3 is electrically connected to the key blade 911 in a state in which the key blade 911 is sandwiched between the pair of key blade receiving pieces 31, and mechanically holds the key blade 911.

The pair of terminal members 2 are held by the terminal spacer 45 as shown in FIGS. 4B and 5B. Here, the pair of terminal members 2 are arranged at positions corresponding to one pair of terminal holes 121 formed on the rear surface of the terminal spacer 45, respectively. Each terminal member 2 is a plug-in quick-connect terminal connected to the power supply line 92 by inserting the core wire 921 of the power supply line 92. Specifically, each terminal member 2 includes a terminal plate 21 and a lock spring 22 as shown in FIG. 5B. The terminal board 21 is made of conductive metal, such as copper or copper alloy. The lock spring 22 is made of elastic metal, such as stainless steel. In each terminal member 2, when the power supply line 92 is inserted into the terminal hole 121 opened on the rear surface of the housing 4, the core wire of the power supply line 92 is sandwiched between the terminal plate 21 and the lock spring 22, and the power supply The wires 92 are electrically connected and mechanically hold the power supply wires 92.

Furthermore, the terminal spacer 45 holds a ground terminal 116 for connecting a ground wire (refer to FIG. 4B). The ground terminal 116 is the same plug-in quick-connect terminal as the terminal member 2 and is arranged at a position corresponding to the ground terminal hole 122 formed on the rear surface of the terminal block 45. The ground terminal 116 is electrically connected to the first ground member 114 and the second ground member 115 in the housing 4.

The temperature detection unit 5 includes a temperature sensor 51. The temperature detection unit 5 is housed in the housing 4. The temperature detection unit 5 uses one temperature sensor 51 to detect the temperature of the detection point group P100 (refer to FIG. 1B) including at least one of the first detection point and the second detection point. The details of temperature will be explained in the paragraph of "(2.2) Composition of temperature detection unit". The temperature sensor 51 is used for the detection end The temperature sensor of the sub-member 2, the connecting member 3, and the internal space 40 of the housing 4 (refer to FIG. 5A). The temperature sensor 51 is realized by, for example, a thermistor, thermocouple, bimetallic sheet, or thermopile.

In this embodiment, the temperature detection unit 5 is provided with only one temperature sensor 51 as a sensor element. The “only one temperature sensor 51 as a sensor element” disclosed in the present invention means that as a sensor element, the number of the temperature sensor 51 is only one, and its intention is not to exclude the temperature detection part 5 When it has components other than sensor components (such as substrates and electronic components). That is, the temperature detection unit 5 has only one temperature sensor 51, and with this one temperature sensor 51, the temperature of the plural detection points P1 to P5 (refer to FIG. 1B) included in the detection point group P100 is detected . Therefore, the temperature sensor 51 is thermally coupled with the plurality of detection points P1 to P5 included in the detection point group P100 through the heat transfer structure 50 described later.

The temperature detection unit 5 outputs a detection signal reflecting the detected temperature detected by the temperature sensor 51 to the control unit 7. The "detection signal" disclosed in the present invention can be a signal (electrical signal) that conveys information about the reaction temperature through a specific symbol, for example, a signal that changes the resistance value, voltage value, or current value in response to temperature. In addition, the detection signal may also be a binary signal that switches on/off (or high level/low level) depending on whether the temperature detected by the temperature detection unit 5 is above the threshold temperature or below the threshold temperature. Furthermore, the temperature detection unit 5 may also include a processing circuit to process the output of the temperature sensor 51 to output a detection signal.

The heat transfer structure 50 thermally couples the detection point group P100 and one temperature sensor 51 as shown in FIG. 1B. The heat transfer structure 50 is a state in which heat (thermal energy) is moved between the detection point group P100 and one temperature sensor 51 by heat conduction, radiation, or convection, or a combination of the like, and is designed to move the detection point A structure in which the group P100 is coupled with one temperature sensor 51 (ie, thermally coupled). The heat transfer structure 50, as an example, may be a member having heat conductivity such as a resin member or a metal member disposed between the detection point group P100 and the temperature sensor 51, or Can be heat pipes, etc. In addition, the heat transfer structure 50 only needs to thermally couple the detection point group P100 and one temperature sensor 51. Therefore, it is not necessary to fill the gap between the detection point group P100 and the temperature sensor 51 without any gaps. A gap (space) is provided between the detection point group P100 and the temperature sensor 51.

In this embodiment, as described above, the temperature detection unit 5 includes only one temperature sensor 51 as a sensor element, so the heat transfer structure 50 includes all the detection points P1 to P5 included in the detection point group P100, It is thermally coupled with a temperature sensor 51. That is, the heat of the plurality of detection points P1 to P5 included in the detection point group P100 is collected in one temperature sensor 51 by the heat transfer structure 50.

In addition, in the present embodiment, the heat transfer structure 50 and the conductive member that electrically connects the terminal member 2 and the connection member 3 are different members. The "conductive member" disclosed in the present invention is conductive, and is a member that constitutes at least a part of the current path between the terminal member 2 and the connecting member 3, for example, includes a lead plate 30 and a movable contact that connects the opening and closing portion 6 Braided wires connected to the wire board 30, etc. In short, the heat transfer structure 50 is a different member from these conductive members (wire plate 30 and braided wires, etc.). Since the electrical connection between the terminal member 2 and the connecting member 3 is ensured by the conductive member, the transmission The thermal structure 50 may not have conductivity.

Specifically, the heat transfer structure 50, as shown in FIG. 5A, is realized by an embedding material filled into the internal space 40 of the housing 4. That is, in the present embodiment, the internal space 40 of the casing 4 is filled with an embedding material of synthetic resin having electrical insulation, and the embedding material is cured to form the heat transfer structure 50. The embedding material should have high heat transfer. The embedding and sealing material constituting the heat transfer structure 50 may be filled in at least a part of the internal space 40, and the entire internal space 40 may not be filled.

(2.2) Composition of temperature detection section

Next, with reference to FIGS. 1B and 4A to 5B, the configuration of the temperature detection unit 5 will be described in detail.

In this embodiment, the temperature sensor 51 of the temperature detection unit 5 (refer to FIG. 1A) is arranged in the internal space 40 of the housing 4, as shown in FIG. 5A, for example. Specifically, the temperature sensor 51 is located behind the internal partition 44 in the internal space 40 and is arranged at a position away from the internal partition 44. In more detail, as shown in FIG. 4A, the temperature sensor 51 is arranged at a position slightly above the center of the inner shelf 44 in a front view. That is, in the front view, the temperature sensor 51 is located between a pair of lead plates 30 that have different polarities. In the vertical direction, they are arranged on two connecting members of the same polarity connected by the lead plates 30. 3 in the position near the upper connecting member 3.

In the housing 4, a pair of terminal members 2 and two pairs (4) of connecting members 3 are housed. In addition, the internal space 40 of the housing 4 is filled with the embedding material as the heat transfer structure 50 as described above, so the temperature sensor 51 is embedded in the heat transfer structure 50 (embedded material). Thereby, in the housing 4, the heat generated in the terminal member 2 or the connecting member 3 is transferred to the temperature sensor 51 through the heat transfer structure 50 arranged in the internal space 40. In this embodiment, the temperature sensor 51 is arranged slightly above the center of the inner shelf 44 in consideration of the nature of heat that heat easily moves upward.

With the above configuration, as shown in FIG. 1B, the temperature sensor 51 can detect the temperature of the detection points P1 to P5 provided in the terminal member 2, the connecting member 3 and the internal space 40. Here, the detection point P1 and the detection point P2 are respectively provided at one and the other detection points of a pair of terminal members 2 of opposite polarities. The detection point P3 and the detection point P4 are respectively set at the detection points of one and the other of the pair of connecting members 3 of opposite polarities. The detection point P5 is a detection point provided in the internal space 40 of the housing 4. FIG. 1B illustrates the detection points P1 to P5 conceptually as the detection point group P100 to be the temperature detection target of the temperature sensor 51, and the meaning is not to specify the specific positions of the detection points P1 to P5.

The combination of the detection point P1 and the detection point P2 (or the combination of the detection point P3 and the detection point P4) among the detection points P1 to P5 becomes a plurality of first detection points that are electrically insulated from each other. That is, for example, the detection point P1 and the detection point P2 are provided at the detection points of one and the other of the terminal member 2 of a pair of opposite polarities, and therefore correspond to the plural first detection points. On the other hand, the combination of the detection point P1, the detection point P3, and the detection point P5 (or the combination of the detection point P2, the detection point P4, and the detection point P5) is provided in the terminal member 2, the connection member 3, and the housing 4. A plurality of second detection points at different locations in the internal space 40. That is, for example, the detection point P1, the detection point P3, and the detection point P5 are detection points provided in the internal space 40 of the terminal member 2, the connection member 3, and the housing 4, respectively, and therefore correspond to the plural second detection points.

In this embodiment, the detection point group P100 that becomes the temperature detection target of one temperature sensor 51 includes all the detection points P1 to P5, that is, both the plural first detection points and the plural second detection points. In short, the detection point group P100 includes a plurality of first detection points constituted by the combination of the detection point P1 and the detection point P2, or the combination of the detection point P3 and the detection point P4, and the detection point P1 and the detection point P3 The combination of the detection point P5, or the combination of the detection point P2, the detection point P4, and the detection point P5 constitutes both of the plurality of second detection points.

Here, the temperature of the connecting member 3 detected by the temperature detection unit 5 is, as an example, the temperature at any one of the plurality of detection points P101 to P111 shown in FIG. 5A. In other words, the detection point P3 and the detection point P4 provided on the connecting member 3 are respectively selected from the plural detection points P101 to P111 shown in FIG. 5A. That is, the temperature rise of the connecting member 3 often occurs because the part of the connecting member 3 that is in contact with the pin blade 911 becomes a heat source. Therefore, the detection point P3 or the detection point P4 provided in the connecting member 3 is selected from, for example, the detection points P101, P102, P110, and P111 near the part of the connecting member 3 that is in contact with the pin blade 911. In addition, if the temperature of any one of the connecting members 3 rises, the heat of the connecting member 3 is transferred to the lead plate 30 and the The other connecting members 3 connected by the lead plate 30 are transmitted. Therefore, the detection point P3 or the detection point P4 provided on the connecting member 3 may be, for example, the detection point P107 set at the center of the lead plate 30 in the upper and lower direction.

Furthermore, if the temperature of the connecting member 3 rises, heat from the connecting member 3 or the lead plate 30 may be transferred to the holding member holding the connecting member 3. In particular, when the holding member is a member made of synthetic resin such as the inner frame 44 and the outer cover 42 as in the present embodiment, the characteristics of the holding member (the inner frame 44 and the outer cover 42) are affected by heat. There are cases where the characteristics of the holding member change (including deterioration, discoloration, and deformation). Therefore, the detection point P3 or the detection point P4 provided on the connection member 3, for example, can also be from the connection member 3 and the lead plate 30 approaching the detection point P105 of the part in contact with the holding member (internal partition 44 and housing cover 42) , P106, P108, P109 selection.

In addition, the temperature of the terminal member 2 detected by the temperature detection unit 5 is, as an example, the temperature at any one of the plurality of detection points P121 to P125 shown in FIG. 5B. That is, the temperature rise of the terminal member 2 often occurs because the portion of the terminal member 2 in contact with the core wire 921 becomes a heat source. Therefore, the detection point P1 or the detection point P2 provided in the terminal member 2 can be selected from, for example, the detection points P124 and P125 near the part of the terminal member 2 that is in contact with the core wire 921. Moreover, if the temperature of the terminal member 2 rises, this heat will be transmitted to the whole terminal board 21 by thermal conduction. Therefore, the detection point P1 or the detection point P2 provided on the terminal member 2 may be, for example, the detection point P122 of the part of the terminal board 21 far from the contact with the core wire 921.

In addition, when the temperature of the terminal member 2 rises, heat from the terminal member 2 may be transferred to the holding member that holds the terminal member 2. In particular, when the holding member is a synthetic resin member such as the terminal spacer 45 as in the present embodiment, the characteristics of the holding member (terminal spacer 45) are affected by heat, and the characteristics of the holding member are changed ( Including deterioration, discoloration and deformation). because Here, the detection point P1 or the detection point P2 provided in the terminal member 2 may be selected from, for example, the detection points P121 and P123 near the contact portion of the terminal member 2 with the holding member (terminal spacer 45).

Furthermore, if the temperature of the connecting member 3 rises, the temperature of the internal space 40 (refer to FIG. 5A) of the housing 4 will also rise due to heat dissipation from the connecting member 3 or the lead plate 30. Similarly, if the temperature of the terminal member 2 rises, the temperature of the internal space 40 of the housing 4 also rises due to heat dissipation from the terminal plate 21 or the lock spring 22. Therefore, the temperature detection unit 5 can also detect the temperature of the detection points P112, P113, P114 (refer to FIG. 5A), etc., set in the internal space 40 of the housing 4, instead of the connecting member 3, the lead plate 30, or the terminal member 2. Therefore, the temperature of the connecting member 3 or the terminal member 2 can be detected indirectly. That is, the detection point P5 provided in the internal space 40 of the housing 4 is selected from the detection points P112, P113, and P114, for example.

The arrangement of the temperature sensor 51 shown in FIGS. 5A and 5B and the positions of the detection points P101 to P114, and P121 to P125 are just an example, and can be changed as appropriate.

As described above, the temperature detection unit 5 uses one temperature sensor 51 to detect the temperature of the detection points P1 to P5 provided in the terminal member 2, the connection member 3, and the internal space 40, for example, by the following configuration , Can distinguish the temperature of detection points P1~P5.

That is, as described above, for example, the temperature rise of the connecting member 3 often occurs because the part of the connecting member 3 in contact with the pin blade 911 becomes a heat source. On the other hand, the temperature rise of the terminal member 2 is mostly caused by the terminal member 2. The part in contact with the core wire 921 becomes a heat source and occurs. Furthermore, the temperature increase of the internal space 40 of the housing 4 occurs due to the temperature increase of the terminal member 2 or the connection member 3. Therefore, the characteristics of temperature changes are set at the detection points P1, P2 of the terminal member 2 and the detection points P3, P2 of the connection member 3 P4, the detection point P5 provided in the internal space 40 of the housing 4 is different. Therefore, the temperature detection unit 5 or the control unit 7 can distinguish the temperatures of the detection points P1 to P5 by performing analysis processing on the output of the temperature sensor 51.

As an example, immediately after the start of the power supply to the outlet system 10, that is, immediately after the start of the outlet system 10, if the temperature rises rapidly in a few seconds, it is estimated that the temperature rises at the detection points P1 and P2 provided at the terminal member 2 . On the other hand, when a predetermined time has elapsed since the energization of the outlet system 10, the temperature rises rapidly within a few seconds, it is estimated that the temperature of the detection points P3 and P4 provided at the connection member 3 has risen. In addition, when the temperature gradually rises within one hour, it is estimated that the temperature of the detection point P5 provided in the internal space 40 of the housing 4 rises.

(2.3) Operation

Next, the operation of the outlet system 10 of this embodiment will be described.

As the basic operation of the outlet system 10, the opening and closing unit 6 operates by switching from the on state to the off state when the determination condition is satisfied. The judgment condition includes that the detected temperature is higher than the threshold temperature. Here, the detected temperature is the temperature of at least one of the terminal member 2 and the connecting member 3 detected by the temperature detecting unit 5. The opening and closing section 6 can be switched from the blocking state to the conducting state when the determination condition is not satisfied.

The "switchable from the cut-off state to the on-state" disclosed in the present invention refers to a state that allows the switching of the open-close portion 6 from the cut-off state to the on-state, that is, a state that allows the open-close portion 6 in the cut-off state to be switched to the on state . Therefore, if it is not "switchable from the blocking state to the conducting state", the switching of the opening and closing portion 6 in the blocking state to the conducting state is prohibited, and the blocking state is maintained. Here, the switching of the opening and closing part 6 from the off state to the on state can be performed manually by the user, or by the socket system 10. For example, it will be automatically executed when it receives a recovery signal from the outside of the socket 1, or meets the recovery conditions such as a predetermined time.

In this embodiment, the control unit 7 receives the detection signal from the temperature detection unit 5 to obtain the detected temperature. Then, the control unit 7 compares the threshold temperature stored in the memory or the like with the detected temperature, and executes the judgment of the judgment condition. When the control unit 7 determines that the determination condition is satisfied, it outputs a drive signal to the opening/closing unit 6 to switch the opening/closing unit 6 from the conducting state to the blocking state. In addition, in this embodiment, as an example, the determination condition is only that the detected temperature is equal to or higher than the threshold temperature. That is, if the detected temperature is higher than the threshold temperature, the determination condition is satisfied, and if the detected temperature is less than the threshold temperature, the determination condition is not satisfied.

Here, in the present embodiment, the temperature detection unit 5 detects the temperature of the connection member 3 as the detection temperature, and detects the temperature of the terminal member 2 as the auxiliary detection temperature. The opening and closing section 6 switches from the conducting state to the shut-off state when satisfying the assist determination condition including the assist detection temperature being equal to or higher than the assist threshold temperature, and restricts switching from the shut-off state to the conducting state. That is, in the present embodiment, the temperature detection unit 5 detects only the temperature of the terminal member 2 and the connection member 3 of the connection member 3 as the detection temperature, and the temperature of the terminal member 2 is the auxiliary detection temperature different from the detection temperature And detection.

Therefore, regarding the temperature of only the connecting member 3 of the terminal member 2 and the connecting member 3, when the determination condition is satisfied, the opening and closing portion 6 is switched from the conducting state to the blocking state, and when the determination condition is not satisfied, the opening and closing portion 6 can Switch from the off state to the on state. Regarding the temperature of the terminal member 2 (auxiliary detection temperature), when the auxiliary determination condition is satisfied, the opening and closing portion 6 switches from the conductive state to the blocking state, but the switching from the blocking state to the conductive state is restricted. That is, when the auxiliary detection temperature satisfies the auxiliary determination condition, even if the auxiliary determination condition is not satisfied, the switching of the opening and closing section 6 from the blocking state to the conducting state is restricted (for example, prohibited).

In the present embodiment, as an example, the auxiliary determination condition is that the auxiliary detection temperature is equal to or higher than the auxiliary threshold temperature, similarly to the determination condition. That is, if the auxiliary detection temperature is equal to or higher than the auxiliary threshold temperature, the auxiliary judgment condition is satisfied, and if the auxiliary detection temperature is less than the auxiliary threshold temperature, the judgment condition is not satisfied. The same applies to the reminder judgment conditions used to judge whether to execute the notification by the notification unit 71. In the present embodiment, only the detected temperature is higher than the reminder temperature. That is, if the detected temperature is higher than the reminder temperature, the reminder judgment condition is satisfied, and if the detected temperature is less than the reminder temperature, the reminder judgment condition is not satisfied.

In addition, in the present embodiment, as the display mode of the display unit 82, there are a plurality of modes by the combination of the lighting state (light off, lighting, flashing, etc.) of the first display lamp 821 and the second display lamp 822 The display state. For example, the display unit 82 performs a "normal" display by turning on the first indicator lamp 821 and turning off the second indicator lamp 822 when the opening/closing portion 6 is in a steady state of the on state. On the other hand, when the alarm determination condition including the detection temperature of the temperature detection unit 5 being higher than the alarm temperature lower than the threshold temperature is satisfied, the display unit 82 turns on the first indicator lamp 821 to turn on the second indicator lamp 822 flashes, and "reminder" is displayed. Furthermore, when the opening and closing section 6 is switched from the on state to the off state, the display section 82 turns on the first display lamp 821 and turns on the second display lamp 822 to display "warning".

Similarly, as the aspect of the output sound from the buzzer 83, there are also a plurality of patterns including a reminder sound to realize the notification of the notification unit 71 and a warning sound to realize the notification of the status notification unit 72. That is, the buzzer 83 stops when the opening and closing section 6 is in the steady state of the conducting state; when the alarm determination condition including the detection temperature of the temperature detection section 5 is higher than the alarm temperature lower than the threshold temperature is satisfied, the alarm sound is output . Furthermore, when the opening and closing unit 6 is switched from the conducting state to the blocking state, the buzzer 83 outputs a warning sound different from the warning sound.

In addition, in this embodiment, the threshold temperature is set to the detected temperature when the characteristic of the under-holding member undergoes a predetermined change. That is, as described above, when heat from the connecting member 3 is transferred to the holding members (internal partition 44 and housing cover 42) of the holding connecting member 3, the characteristics of the holding member are affected by the heat, and there is Changes in the characteristics of components (including deterioration, discoloration and deformation). On the other hand, in the outlet system 10 of this embodiment, the outlet 1 can be used again even after the temperature rise occurs. Therefore, the opening and closing portion 6 should be cut off so that the characteristics of the holding member do not exceed the allowable range. The "predetermined change" disclosed in the present invention is a change when the change in the characteristics of the holding member reaches the upper limit of the allowable range. For example, if the allowable range of the characteristics of the holding member is determined in a specific specification, it is advisable to keep the characteristics of the holding member within this allowable range even if the temperature rises. Therefore, by making the temperature of the detected temperature when the characteristic of the under-holding member undergoes a predetermined change as the threshold temperature, the opening and closing portion 6 can be shut off before the characteristic of the holding member changes more than the predetermined change. Thereby, before the characteristic of the holding member deteriorates, the opening and closing portion 6 is in a blocked state to suppress further temperature rise, and it is possible to prepare for the re-use of the socket 1.

In addition, the outlet system 10 of the present embodiment is provided with an operating member 81 that accepts operations from the user as described above, and the operating member 81 is linked with the opening and closing portion 6. Therefore, the opening and closing portion 6 is switched from the blocking state to the conducting state by the operation (recovery operation) of the operating member 81 when the determination condition is not satisfied. That is, after the determination condition is satisfied and the opening and closing section 6 is switched from the conducting state to the blocking state, if the factor that satisfies the determination condition is removed and the recovery operation is performed in the state where the determination condition is not satisfied, the opening and closing section 6 is switched from the blocking state to Conduction state. Thereby, the user can manually switch the opening and closing portion 6 from the blocking state to the conducting state.

In addition, in this embodiment, as described above, the operating member 81 moves between the open position and the closed position in conjunction with the opening and closing portion 6. That is, according to the position of the operating member 81, the opening and closing portion 6 is in a conductive state. Or it is in a blocked state, so the operating member 81 also functions as a state prompting section for prompting the state of the opening and closing section 6. In this embodiment, because the operating member 81 is only visible when the operating member 81 is in the closed position, it is painted red, so that the operating member 81 can be visually confirmed in the open position and closed even at a distance. What is the location.

Hereinafter, an example of the operation of the outlet system 10 of this embodiment will be described with reference to the flowchart of FIG. 6. In addition, the flowchart of FIG. 6 is only an example, and the order of processing can be changed as appropriate, and processing can be added or omitted as appropriate.

In FIG. 6, first, the control unit 7 receives the detection signal from the temperature detection unit 5 to obtain the actual temperature T1 (S1). The actual measured temperature T1 includes both the temperature of the connection member 3 (detected temperature) and the temperature of the terminal member 2 (auxiliary detection temperature).

Next, the control unit 7 compares the actual temperature T1 with the warning temperature Tth1 (S2). The reminder temperature Tth1 is a temperature that is compared with the detected temperature in order to determine whether the reminder determination condition is satisfied, that is, whether the notification by the notification unit 71 is executed. The reminder temperature Tth1 is a temperature lower than the threshold temperature Tth2. If the measured temperature T1 is less than the reminder temperature Tth1 (S2: No), the control unit 7 determines that the reminder judgment condition is not satisfied, and executes the stop processing of the buzzer 83 (S3) and the "normal" display of the display unit 82 ( S4), return to processing S1.

On the other hand, in process S2, if the actual measured temperature T1 is greater than or equal to the reminder temperature Tth1 (S2: Yes), the control unit 7 determines that the reminder determination condition is satisfied, and executes the notification from the notification unit 71, that is, from the buzzer 83 The alert sound is output (S5), and "reminder" is displayed on the display section 82 (S6). In this state, if the switch 84 is pressed and operated, that is, the stop button of the buzzer 83 is pressed (S7: Yes), the control unit 7, The stop process of the buzzer 83 is executed (S8), and the actual temperature T1 is acquired (S9). If the switch 84 is not pressed, that is, the stop button of the buzzer 83 is not pressed (S7: No), the control unit 7 skips the stop process of the buzzer 83 (S8), and obtains the actual temperature T1 (S9) .

Next, the control unit 7 compares the actual temperature T1 acquired in the process S9 with the threshold temperature Tth2 (S10). The threshold temperature Tth2 is a temperature to be compared with the detected temperature in order to determine whether or not the determination condition is satisfied, that is, whether the opening and closing portion 6 is turned off. Furthermore, in the present embodiment, the threshold temperature Tth2 also serves as an auxiliary threshold temperature to be compared with the auxiliary detection temperature to determine whether the auxiliary determination condition is satisfied. That is, the auxiliary threshold temperature is equal to the threshold temperature Tth2. If the actually measured temperature T1 is less than the threshold temperature Tth2 (S10: No), the control unit 7 determines that the determination condition and the auxiliary determination condition are not satisfied, and returns to the process S1.

Therefore, even if the notification by the notification unit 71 is determined to meet the reminder determination condition, if the measured temperature T1 drops below the reminder temperature Tth1 (S2: No), the buzzer 83 is stopped. (S3), and "normal" display on the display portion 82 (S4). Therefore, for example, even if a temperature rise due to a temporary event occurs, and the actual measured temperature T1 rises and it is determined that the warning temperature Tth1 is higher, if the actual measured temperature T1 decreases thereafter, the notification by the notification unit 71 is automatically stopped.

On the other hand, in process S10, if the actual measured temperature T1 is greater than or equal to the threshold temperature Tth2 (S10: Yes), the control unit 7 determines that the judgment condition or the auxiliary judgment condition is satisfied, and outputs a drive signal to the opening and closing unit 6 to turn the opening and closing unit 6 Switch from the on state to the off state (S11). Then, the control unit 7 executes the notification of the status notification unit 72, that is, the output of the warning sound from the buzzer 83 (S12), and the "warning" display of the display unit 82 (S13). In this state, if the switch 84 is pressed, that is, the stop button of the buzzer 83 is pressed (S14: Yes), the control unit 7 executes the stop process of the buzzer 83 (S15), and the process proceeds to S16. If the switch 84 is not pressed, that is, the stop button of the buzzer 83 is not pressed (S14: No), the control unit 7 skips the stop process of the buzzer 83 (S15) and proceeds to the process S16.

In process S16, the control unit 7 determines whether or not the actual temperature T1 determined to be greater than or equal to the threshold temperature Tth2 is the temperature of the connecting member 3. That is, if the actual temperature T1 at this time is the temperature of the connecting member 3 (S16: Yes), it is determined that the determination condition is satisfied in the process S10, so the control unit 7 goes to the switchable part 6 to be shut off. Process S17 for switching to the conductive state. In this state, when the restoration operation of the operating member 81 is performed (S17: Yes), the opening and closing section 6 is switched from the blocking state to the conducting state (S18), and the process proceeds to S9. At this time, if the factor of the determination condition has not been released, that is, the actual measured temperature T1 is still greater than the threshold temperature Tth2 (S10: Yes), the control unit 7 immediately switches the opening and closing unit 6 from the on state to the off state (S11). On the other hand, if the factor of the determination condition is cancelled and the actual temperature T1 is less than the threshold temperature Tth2 (S10: No), the control unit 7 determines that the determination condition and the auxiliary determination condition are not satisfied, and returns to the process S1. Thereby, the opening and closing portion 6 is maintained in a conductive state, and the socket 1 becomes a state in which it can be used again.

On the other hand, in process S16, when it is determined that the actual temperature T1 determined to be greater than or equal to the threshold temperature Tth2 is not the temperature of the connecting member 3 (S16: No), in process S10, it is determined that the auxiliary determination condition is satisfied. In this case, the control unit 7 proceeds to the process S19 in which the opening and closing unit 6 cannot be switched from the blocking state to the conducting state. In this state, if the restoration operation of the operating member 81 is performed (S19: Yes), the control section 7 forcibly maintains the opening and closing section 6 in the blocking state by the drive signal (S11).

In addition, if the recovery operation (S17: No or S19: No) is not performed in any of the processes of the process S17 and the process S19, the control unit 7 proceeds to the process S14.

In the above-mentioned outlet system 10, when the determination condition is not satisfied, the opening and closing unit 6 can be switched from the cut-off state to the on-state. That is, in the outlet system 10, even if the opening/closing section 6 was once in a disconnected state due to the satisfaction of the judgment condition, if the factor for satisfying the judgment condition is removed later and the judgment condition is not satisfied, the opening/closing section 6 can be restored to the on state. Therefore, according to the outlet system 10, even if the opening/closing part 6 has been in a blocked state, by restoring the opening/closing part 6, the outlet system 10 (outlet 1) can be used again without replacing the outlet system 10 (outlet 1). Therefore, for example, when the temperature rise is caused by a temporary event, or caused by an electrical appliance connected to the socket 1, the original socket 1 does not need to be replaced, and the socket 1 does not need to be replaced, which improves the socket system 10 convenience.

(3) Modifications

The above-mentioned embodiment is only an example of the various embodiments disclosed in the present invention. If the above embodiment can achieve the purpose disclosed in the present invention, various changes can be made in accordance with the design and the like. In addition, the control method of the socket 1, a computer program, or a non-temporary recording medium on which the computer program is recorded can be used to specifically realize the same functions as the control unit 7 of the above-mentioned embodiment.

Hereinafter, modified examples of the above-mentioned embodiment are listed. The modified examples described below can be appropriately combined and applied.

The socket system 10 disclosed in the present invention, for example, the control unit 7 and the like, includes a computer system. A computer system is mainly composed of a processor and memory as hardware. The function of the control unit 7 disclosed in the present invention is realized by enabling the processor to execute the program recorded in the memory of the computer system. The program can be pre-recorded in the memory of the computer system, can be provided through electrical communication lines, and can also be recorded on non-temporary recording media such as memory cards, optical discs, and hard disks that can be read by the computer system. The processor of a computer system is one or more including semiconductor integrated circuit (IC) or large integrated circuit (LSI) Electronic circuit composition. Multiple electronic circuits can be integrated into one chip, or can be distributed on multiple chips. Multiple chips can be integrated into one device or distributed in multiple devices.

In addition, integrating the multiple functions of the socket system 10 into one housing 4 is not a necessary configuration for the socket system 10, and the components of the socket system 10 may be distributed in multiple housings. Further, the control unit 7 and the like, for example, can implement at least a part of the functions of the socket system 10 by means of cloud (cloud computing). Conversely, it is also possible to integrate all the functions of the socket system 10 into one housing 4 as in the above-mentioned embodiment.

In addition, the control unit 7 can be omitted as appropriate, and is not a necessary configuration for the outlet system 10. That is, if the outlet system 10 is operated when the judgment condition is satisfied, the opening and closing section 6 is switched from the on state to the off state, and when the judgment condition is not satisfied, the opening and closing section 6 can be switched from the off state to the on state. . Therefore, for example, when the output (detection signal) of the temperature detection unit 5 is directly input to the opening and closing unit 6 and the opening and closing unit 6 receives the detection signal and operates, the control unit 7 can be omitted. Furthermore, for example, when the temperature detection part 5 is a bimetal or the like and the opening and closing part 6 is directly driven, the control part 7 may be omitted.

In addition, in the above-mentioned embodiment, although the case where the temperature detection part 5 detects the temperature of the connection member 3 as a detection temperature, and detects the temperature of the terminal member 2 as an auxiliary detection temperature was demonstrated, it is not limited to this example. For example, the temperature detection unit 5 may detect the temperature of the terminal member 2 or the temperature of both the terminal member 2 and the connection member 3 as the detected temperature. In the case where the temperature of both the terminal member 2 and the connecting member 3 is used as the detection temperature, the determination condition is that the detection temperature of the terminal member 2 and the detection temperature of the connection member 3 may be the same or different.

In addition, as long as the determination condition includes that the detected temperature is equal to or higher than the threshold temperature, other conditions may be included in addition to the detected temperature being equal to or higher than the threshold temperature. For example, the determination conditions may also include events where the detected temperature is higher than the threshold temperature for a predetermined time, a predetermined number of occurrences, or a frequency higher than a predetermined value. The same applies to the assist determination conditions, as long as it includes the assist detection temperature being equal to or higher than the assist threshold temperature, and other conditions may be included in addition to the assist detection temperature being equal to or higher than the assist threshold temperature. The same applies to the reminder determination condition, as long as it includes that the detected temperature is higher than the reminder temperature, other conditions may be included in addition to the detected temperature being higher than the reminder temperature.

In addition, the socket 1 is not limited to being provided with a grounding electrode, and may not be provided with a grounding electrode. For example, it may be a socket (Concent, Outlet) for AC power or DC power. Furthermore, the socket 1 is not limited to an A-type socket. For example, it may also be a B-type or C-type socket that can be connected to a plug with pin-shaped blades. The socket 1 is not limited to a double-port type, for example, it may be a single-port type or a three-port type. Furthermore, the socket system 10 not only includes the socket 1, but may further include a human body sensor, a timer, a switch, etc., for example. In addition, the terminal member 2 may not be a quick-connect terminal, for example, it may be a screw terminal. In addition, the socket 1 is not limited to a configuration in which the rear part is embedded in the construction surface 100 by using a mounting frame (insertion installation type), and it may also be a configuration in which the entirety is exposed on the construction surface 100 (exposed installation type).

In addition, the socket 1 may also have a locking mechanism that serves as a fixing member of the plug 91. The locking mechanism, for example, fixes the bolt blade 911 of the plug 91 by rotating the plug 91. Socket 1, can also be attached with a protective door.

In addition, in the above embodiment, if the electromagnetic release device is actuated and the opening and closing portion 6 is switched from the conducting state to the blocking state, the operating member 81 also moves to the closed position in conjunction with the opening and closing portion 6, but it is not limited to this configuration. For example, when the opening and closing portion 6 is switched from the on state to the off state, the operating structure The piece 81 is maintained in the open position. In this case, the recovery operation is achieved by first moving the operating member 81 from the open position to the closed position, and then moving the operating member 81 from the closed position to the open position.

In addition, the opening and closing portion 6 may be realized by, for example, a mechanical relay or a semiconductor switch.

In addition, the temperature detection unit 5 may include at least one temperature sensor 51, and may include one or more other temperature sensors in addition to the one temperature sensor 51. In this case, one temperature sensor 51 also detects the temperature of the detection point group P100 including at least one of the plurality of first detection points and the plurality of second detection points as the detection temperature.

In addition, the heat transfer structure 50 is not limited to the embedding material filled into the internal space 40 of the housing 4, and may also be other resin members or metal members with heat transfer properties, or may be heat pipes, etc. Realized by their combination. In this case, the embedding material filled in the internal space 40 can be omitted. Furthermore, the heat transfer structure 50 can be integrated with a conductive member that electrically connects the terminal member 2 and the connection member 3. In other words, the conductive member (wire plate 30, braided wire, etc.) can also be used as the heat transfer structure 50.

In addition, in the above-mentioned embodiment, the state of presentation by the state presentation unit 72 is the same regardless of whether the judgment condition is satisfied or the auxiliary judgment condition is satisfied. However, it is not limited to this form, and may be the case when the judgment condition is satisfied. When the auxiliary determination condition is satisfied, the state presentation unit 72 is caused to perform presentation in a different manner. As an example, when it is determined that the actual measured temperature T1 above the threshold temperature Tth2 is the temperature of the connecting member 3, the first indicator lamp 821 may be lit, and when the actual measured temperature T1 is the temperature of the terminal member 2, the first display The lamp 821 flickers, etc., so that the display mode of the display unit 82 is different.

In the content disclosed in the present invention, in the comparison of two values such as the detected temperature and the threshold temperature, the reference to "above" includes both the case where the two values are equal and the case where one of the two values exceeds the other. However, it is not limited to this form, and "above" mentioned here may be synonymous with "greater" which only includes a case where one of the two values exceeds the other. That is, whether or not the two values are equal can be changed arbitrarily according to the setting of the reference value, etc., so "above" or "greater" does not have a technical difference. Similarly, when referring to "not full", it is also synonymous with "below".

(Embodiment 2)

The outlet system 10A of this embodiment is different from the outlet system 10 of the first embodiment in that the outlet 1A is equipped with a temperature sensor 52 as shown in FIGS. 7A and 7B. Hereinafter, for the same configuration as that of the first embodiment, common symbols are given, and descriptions are appropriately omitted.

That is, in this embodiment, the temperature detection unit 5 includes a temperature sensor 51 (hereinafter also referred to as "first temperature sensor 51") and a temperature sensor 52 (hereinafter also referred to as "second temperature sensor Detector 52") These two sensor elements. The second temperature sensor 52 is, like the first temperature sensor 51, for example, a thermistor, thermocouple, bimetal, or thermopile.

The first temperature sensor 51 is a sensor for detecting the temperature of the connecting member 3. The second temperature sensor 52 is a sensor for detecting the temperature of the terminal member 2. Therefore, the first temperature sensor 51 is thermally coupled with the detection points P3 and P4 (refer to FIG. 1B) provided in the connecting member 3 by the heat transfer structure 50; the second temperature sensor 52 is thermally coupled with the heat transfer structure 50 and thermally coupled to the detection points P1 and P2 (refer to FIG. 1B) provided on the terminal member 2.

The second temperature sensor 52 is, for example, arranged in the internal space 40 of the housing 4 (refer to FIG. 5A). Specifically, the second temperature sensor 52 is arranged behind the terminal spacer 45 in the internal space 40, as shown in FIGS. 7A and 7B. In more detail, the second temperature sensor 52, as shown in FIG. 7A, is arranged between a pair of terminal members 2 having different polarities in a front view.

With the above configuration, the second temperature sensor 52 can detect the temperature of the detection points P1 and P2 provided in the terminal member 2. Here, the detection point P1 and the detection point P2 are set at the detection points of one and the other of the terminal member 2 of a pair of opposite polarities. Therefore, the combination of the detection point P1 and the detection point P2 becomes electrically insulated from each other Plural number 1 detection point. That is, the detection point group that becomes the temperature detection target of the second temperature sensor 52 includes a plurality of first detection points (detection points P1 and P2). On the other hand, the first temperature sensor 51 can detect the temperature of the detection points P3 and P4 provided on the connecting member 3. Here, the detection point P3 and the detection point P4 are set at the detection points of one and the other of the connecting member 3 of a pair of opposite polarities. Therefore, the combination of the detection point P3 and the detection point P4 becomes electrically insulated from each other Plural number 1 detection point. That is, the detection point group that becomes the temperature detection target of the first temperature sensor 51 includes a plurality of first detection points (detection points P3 and P4).

According to the configuration of this embodiment, one temperature sensor (51 or 52) detects the temperature of a plurality of first detection points that are electrically insulated from each other, so that the number of temperature sensors required for the number of detection points The number of parts is suppressed to a small amount, which can suppress the increase in the number of parts. In addition, the temperature of the terminal member 2 and the temperature of the connecting member 3 are detected by different temperature sensors 51 and 52, so it is easy to distinguish the temperature of the terminal member 2 from the temperature of the connecting member 3.

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