Further, the operating member 79 presses the intermediate portion of the N-phase movable terminal plate 83. An N-phase movable terminal portion 84 is fixed to the other end of the N-phase movable terminal plate 83 by, for example, caulking. As will be described later, when the actuating member 79 rotates in the counterclockwise direction, the N-phase movable terminal plate 83 is pushed up by the rear end portion (lower end portion in FIG. 7) of the actuating member 79, and the N-phase movable terminal portion 84 Is designed to move forward (upper in FIG. 7).

As shown in FIG. 7, the L-phase movable terminal portion 82 is in contact with the L-phase fixed terminal portion 87 arranged in the housing 72 and is electrically connected. The L-phase fixed terminal portion 87 is fixed to one end of the L-phase fixed terminal plate 86 by, for example, caulking. The L-phase fixed terminal plate 86 extends to the outside of the housing 72.

The N-phase movable terminal portion 84 is in contact with the N-phase fixed terminal portion 89 arranged in the housing 72 and is electrically connected. The N-phase fixed terminal portion 89 is fixed to one end of the N-phase fixed terminal plate 88 by, for example, caulking. The N-phase fixed terminal plate 88 extends to the outside of the housing 72.

In the opening / closing unit 70 configured as described above, when power is supplied to the coil 73 by an operation signal from the substrate 120, the movable iron piece 74 is attracted by the magnetic force of the coil 73 and is directed by the arrow A as shown in FIG. Move to.

Then, one end of the operating plate 77 supported by the upper end of the support lever 76 is disengaged, and the operating plate 77 is pushed backward (downward in FIG. 8) by the pressing force of the pressing spring 78. At this time, the operating lever 71 is rotated so that the end portion protrudes from the front surface of the outlet 10 by the reaction force of the pressing spring 78 and the urging force of the torsion spring 90.

When the support lever 76 of the actuating plate 77 is disengaged, the actuating member 79 pushed and supported by the actuating plate 77 in the clockwise direction is rotated counterclockwise by the urging force of the pressure welding spring 80. .. As a result, the L-phase movable terminal plate 81 moves due to the urging force of the pressure contact spring 85, and the L-phase movable terminal portion 82 is separated from the L-phase fixed terminal portion 87. At the same time, the N-phase movable terminal plate 83 is moved so as to be lifted by being pushed by the operating member 79 that rotates in the counterclockwise direction. As a result, the N-phase movable terminal portion 84 is separated from the N-phase fixed terminal portion 89. By separating the L-phase movable terminal portion 82 and the N-phase movable terminal portion 84 from the L-phase fixed terminal portion 87 and the N-phase fixed terminal portion 89, respectively, the opening / closing unit 70 switches from the closed state to the open state. As a result, the power supply to the blade receiving spring blocks 42a and 42b is cut off, and the power supplied from the outlet 10 to the load of the home electric appliance or the like via the plug is turned off. When the abnormal state is released and the operating lever 71 is manually returned from the state shown in FIG. 8 to the state shown in FIG. 7, each component inside the opening / closing unit 70 is also shown in FIG. 7 from the state shown in FIG.

Lock springs 92 and 94 are arranged inside the phase connecting portions 86a and 88a, respectively. As a result, the connection portions 86a and 88a are so-called quick connection terminals that can be quickly connected by inserting the connection terminals of the L-phase and N-phase external power supply lines from the rear.

By pushing the unlocking member 96, the lock springs 92 and 94 can be separated from the phase connection portions 86a and 88a, and as a result, the connection terminals of the L-phase and N-phase external power supply lines are connected to the connection portion. It can be removed from 86a and 88a.

Further, the terminal portion 100 includes a grounding terminal portion 102. The grounding terminal portion 102 includes, for example, a grounding terminal plate 104 formed by punching and bending a metal plate such as a copper plate.

In the present embodiment, the temperature sensor 54 is sandwiched and fixed by a clip 56 which is an example of a pressing member. As a result, the temperature sensor 54 is closely arranged with the blade receiving spring block 42a, which is the temperature measurement target. The clip 56 integrally has a pair of holding pieces 56a and a connecting portion 56b that connects each holding piece 56a.

By sandwiching the temperature sensor 54 by the clip 56 in this way, the temperature sensor 54 is attached in close contact with the connection terminal portion 52 which is the temperature measurement target. This improves the temperature measurement accuracy of the temperature sensor 54. Further, the blade receiving spring blocks 42a and 42b can be easily assembled to the body member 44 in a state where the temperature sensor 54 is attached to the connection terminal portion 52 by the clip 56.

The temperature sensor 54 is preferably composed of a thermistor, a resistance temperature detector, or a thermocouple. In this case, the clip 56 heats any of the thermistor, the resistance temperature detector, and the thermocouple. It is attached in close contact with the connection terminal portion 52 to be measured. Further, a heat conductive member may be interposed between the temperature sensor 54 and the connection terminal portion 52. The heat conductive member is preferably composed of a flexible and thin member such as a sheet or grease having heat conductivity. By providing such a heat conductive member, the temperature sensor 54 tends to be in a state closer to the temperature measurement target, which can contribute to the improvement of the temperature measurement accuracy.

In the present embodiment, an example is given in which the clip 56 is used as a pressing member for pressing the temperature sensor 54 and bringing it into close contact with the connection terminal portion 52 which is the temperature measurement target, but the present invention is not limited to this. .. Instead of the clip 56, the temperature sensor may be pressed against the temperature measurement target by using an urging member such as a coil spring or a leaf spring.

FIG. 13 is a perspective view showing a state in which one blade receiving spring block 42a is assembled to the body member 44. FIG. 14 is an exploded perspective view showing one blade receiving spring block 42a and the body member 44. Note that the temperature sensor 54 and the clip 56 are not shown in FIGS. 13 and 14.

It integrally has a connection terminal portion 52 formed by bending along the front-rear direction Y from the edge portion of the 50. The blade receiving spring 48 includes a pair of blade receiving pieces facing each other. The tip of each blade receiving piece is bent outward so as to open in a substantially V shape. This ensures that the plug blade of the plug is received between the pair of blade receivers.

Further, the blade receiving spring block 42a integrally has U-shaped bending spring portions 49 provided apart from each other on both sides of the blade receiving spring 48 including the pair of blade receiving pieces. The bending spring portion 49 has a bending portion 49a on the same side as the tip end portion of the pair of blade receiving pieces, and also has a pair of stretching portions 49b extending from the bending portion 49a toward the base end portion side of the pair of blade receiving pieces. doing.

The blade receiving spring block 42a is housed and arranged in the body member 44. The body member 44 is formed so as to partition the four recesses 45. Of the inner wall surface that partitions the recess 45, two ribs 47a are formed on the wall surface located on the center side in the width direction X at intervals and extended in the front-rear direction Y. These ribs 47a can increase the strength of the body member 44.

Further, among the inner wall surfaces that partition the recess 45, ribs 47b are formed so as to face each other on the inner wall surface facing the vertical direction Z. As shown in FIG. 13, these ribs 47b are a pair of stretches of bending spring portions 49 located on both sides of the blade receiving spring 48 in the vertical direction Z when the blade receiving spring block 42a is assembled to the body member 44. It is in a state of being sandwiched by the portion 49b. Further, the bent portion 49a of the bent spring portion 49 is in contact with the end portion of the rib 47b.

By assembling the bent portion 49a of the bent spring portion 49 in contact with the end portion of the rib 47b formed on the body member 44 in this way, the blade receiving spring block 42a is accurately positioned with respect to the body member 44. Can be assembled into a state. Further, when the pair of extension portions 49b of the bending spring portion 49 are in a state of sandwiching the rib 47b, the blade receiving spring block 42a can be firmly assembled to the body member 44.

Further, when a force in the width direction X acts on the insertion plug inserted into and removed from the outlet 10, the pair of blade receiving pieces are plastically deformed so as to open abnormally, and the contact pressure between the plug blade and the blade receiving piece. May be weakened. Then, minute light emission discharge or the like may occur due to poor contact, which may cause abnormal overheating. On the other hand, in the outlet 10 of the present embodiment, the rib 47b is sandwiched between the bending spring portion 49 integrally formed with the blade receiving spring 48, so that even if the above-mentioned opening force acts, the pair is paired. It is possible to prevent or suppress the blade receiving spring 48 made of the blade receiving piece from being abnormally opened and deformed.

In the present embodiment, an example in which ribs 47b are formed on the two inner wall surfaces of the recess 45 facing the vertical direction Z and sandwiched by the bending spring portion 49 has been described, but the present invention is not limited to this. The ribs protruding from the inner wall surface of the concave portion 45 in the front-rear direction Y (that is, the bottom surface of the concave portion 45) may be sandwiched between a pair of extending portions of the bending spring portion 49, or the ribs protruding from the bottom surface may be sandwiched. It may be configured to be sandwiched by the base end portion (that is, the end portion on the side opposite to the tip end portion) of the pair of blade receiving pieces.

FIG. 15 is an enlarged perspective view showing a part of the terminal portion. As shown in FIG. 15, a printed circuit board 110 for temperature measurement may be provided. Temperature sensors 112a and 112b are mounted on the printed circuit board 110. The temperature sensors 112a and 112b are preferably configured by, for example, a thermistor, a resistance temperature detector, or a thermocouple. The temperature sensors 112a and 112b may be covered with a heat conductive member and provided on the printed circuit board 110. In this case, the temperature sensors 112a and 112b are joined to the L-phase fixed terminal board 86 and the N-phase fixed terminal board 88, which are the objects of temperature measurement, via the heat conductive member. The heat conductive member is preferably a flexible resin having heat conductivity. As a result, the temperature sensors 112a and 112b come into close contact with the temperature measurement target, and the temperature measurement accuracy can be improved. Further, in order to make the electrical insulation between the L-phase fixed terminal board 86 and the N-phase fixed terminal board 88, which are the objects of temperature measurement, more reliable, the heat conductive member is preferably an insulating resin. As a specific example, a low-hardness acrylic resin can be used as the heat conductive member, and for example, Hypersoft heat dissipation sheets (registered trademark) 6500H, 6510H, 5578H manufactured by 3M can be used.

The temperature sensor 112a mounted on the printed circuit board 110 is joined to the L-phase fixed terminal board 86, and the temperature sensor 112b mounted on the printed circuit board 110 is joined to the N-phase fixed terminal board 88. Then, the temperature of the L-phase fixed terminal board 86 measured by the temperature sensor 112a is transmitted to the control unit 122 of the substrate 120 via the signal line 114a. Further, the temperature of the N-phase fixed terminal board 88 measured by the temperature sensor 112b is transmitted to the control unit 122 of the substrate 120 via the signal line 114b.

The control unit 122 provided on the substrate 120 determines whether or not the fixed terminal temperature measured by the temperature sensors 112a and 112b exceeds a predetermined threshold temperature. Then, when the temperature of at least one of the fixed terminal plates 86 and 88 exceeds the predetermined threshold temperature, the control unit 122 determines that the outlet 10 is in an overheated state, and sends an operation signal to the opening / closing unit 70 via the signal line 60c. To send. As a result, the opening / closing unit 70 operates to open the circuit, and the power supply to the blade receiving spring blocks 42a and 42b is cut off. The predetermined threshold temperature here may be the same value as that compared with the temperature measured by the temperature sensor 54 of the blade receiving spring blocks 42a and 42b described above, or may be set to a higher value. You may.

In the outlet 10 of the present embodiment, the temperature sensors are arranged on both the blade receiving spring blocks 42a and 42b and the fixed terminal plates 86 and 88, but the blade receiving spring blocks 42a and 42b or the fixed terminal plates 86 and 88 have their temperature sensors. The temperature sensor may be arranged in only one of them.

Next, with reference to FIGS. 16 and 17 in addition to FIG. 15, the assembly of the opening / closing unit and the terminal storage box in the outlet 10 of the present embodiment will be described.

FIG. 17 is a side view showing a state in which the terminal storage box 91 is assembled to the opening / closing unit 70.

As shown in FIGS. 15 and 16, a support portion 72a is formed in a portion of the housing 72 of the opening / closing unit 70 facing the terminal portion 100. When the opening / closing unit 70 detects at least one of the blade receiving spring blocks 42a and 42b, and at least one of the L-phase fixed terminal plate 86 and the N-phase fixed terminal plate 88 (that is, overheating), the opening / closing unit 70 is in an open circuit state. As described above, it has a function of cutting off the power supply. Here, the blade receiving spring unit 40 and the terminal portion 100 correspond to the conductive connecting portion, and the blade receiving spring blocks 42a and 42b and the fixed terminal plates 86 and 88 form a conductive path electrically connected to the conductive connecting portion.

The housing 72 of the opening / closing unit 70 is preferably formed of, for example, a resin molded product, and the support portion 72a is integrally provided with the housing 72. The support portion 72a is formed in the shape of a cantilever. More specifically, the base end portion of the support portion 72a is connected to the housing 72 and extends linearly from the base end portion, and the tip end portion thereof is a free end. Further, the support portion 72a is formed in a direction inclined downward (right side in FIG. 16) with respect to the front-rear direction Y. Since the support portion 72a is formed in the shape of an inclined cantilever in this way, when the support portion 72a comes into contact with the support portion 72a when the terminal portion storage box is assembled as described later, the support portion 72a moves upward (FIG. 16). It is elastically deformed by being pressed against the left side of the inside). As a result, the elastically deformed support portion 72a exerts an elastic force on the terminal portion storage box in the plane direction along the plane including the width direction X and the vertical direction Z, and temporarily holds the terminal portion storage box.

It elastically deforms and bends. Then, as shown in FIG. 17, when the assembly of the terminal storage box 91 is completed, the pressure of the supported portion 97 against the support portion 72a of the opening / closing unit 70 is released, and the tip portion of the support portion 72a is supported. It is in a state of being in contact with the contact surface of the portion 97. As a result, the terminal storage box 91 is in a state in which movement in the vertical direction orthogonal to the plane direction along the plane including the width direction X and the vertical direction Z, specifically, the movement in the front-rear direction Y is restricted. As a result, the terminal storage box 91 cannot move in the plane direction including the width direction X and the vertical direction Z and the front-rear direction Y orthogonal to the width direction X and the vertical direction Z in the state of being assembled to the terminal part 100, and the opening / closing unit 70 and the opening / closing unit 70.

For example, in the above description, an example in which the support portion 72a is formed in the opening / closing unit 70 and the supported portion 97 is formed in the terminal portion storage box 91 has been described, but the present invention is not limited thereto. On the contrary, a support portion made of a cantilever-shaped elastic piece may be formed in the terminal storage box 91, and a supported portion having an inclined surface and a contact surface may be formed in the opening / closing unit 70.

Further, in the above, the example in which the movement of the terminal storage box 91 in the plane direction is restricted by the connection portions 86a, 88a and the like of the phase fixing terminal plates 86, 88 housed therein has been described, but the present invention is limited to this. It is not something that will be done.
