A pair of plug blades having a voltage pole of a plug with a ground electrode (so-called 3P plug; hereinafter simply referred to as “plug”) are inserted into the first insertion port 231 and the second insertion port 232. The third insertion port 233 is formed in a circular shape. A pin of a ground electrode of the plug is inserted into the third insertion port 233.

  The first insertion port 231, the second insertion port 232, and the third insertion port 233 are each closed by the shutter 24. When the plug blades and pins of the plug are inserted into the insertion ports 231 to 233, the shutters 24 are pushed by the plug blades and pins so as to move to positions where the insertion ports 231 to 233 are opened. It is configured. Moreover, each shutter 24 is comprised so that it may reset to the position which obstruct | occludes each insertion port 231-233, if the plug blade and pin of a plug are extracted from each insertion port 231-233. Whether or not the connection device 1 includes these shutters 24 is arbitrary.

  The connecting portion 25 includes a first blade receiving portion 251, a second blade receiving portion 252, and a third blade receiving portion 253. The 1st blade receiving part 251 and the 2nd blade receiving part 252 are provided in the position which opposes the 1st insertion port 231 and the 2nd insertion port 232 in the inside of the container 21, respectively. The third blade receiving portion 253 is provided at a position facing the third insertion port 233 inside the container body 21. The first blade receiving portion 251 and the second blade receiving portion 252 are configured such that a pair of plug blades of the plug are in contact with each other and connected.

Accordingly, the pair of plug blades and pins of the plug are inserted into the first insertion port 231, the second insertion port 232, and the third insertion port 233, respectively, so that the first blade receiving unit 251 and the second blade receiving unit are inserted. 252 and the third blade receiving portion 253 are electrically connected. Below, a pair of plug blades and pins of the plug are
Connecting to the first blade receiving portion 251, the second blade receiving portion 252, and the third blade receiving portion 253, respectively, is referred to as “connecting the plug to the outlet block 2”.

  As shown in FIGS. 1A, 1B, and 5, the breaker block 3 includes a casing 31, a circuit breaker 34, a ground terminal 35, and a test switch 36. The breaker block 3 further includes a handle 37 as a part of the circuit breaker 34.

  The housing 31 is formed in a box shape from, for example, a resin material. The housing 31 includes a box-shaped body 32 having one surface (front surface) opened and a box-shaped cover 33 having one surface (rear surface) opened. Specifically, the housing 31 is configured by coupling the body 32 and the cover 33 with the opening of the body 32 and the opening of the cover 33 abutting each other. The cover 33 is provided with a rectangular opening 331. A part of the handle 37 housed inside the housing 31 is exposed from the opening 331.

  The circuit breaker 34 is housed inside the housing 31. As shown in FIG. 5, the circuit breaker 34 is connected between the connecting portion 25 and the AC power source (power source) AC <b> 1. The circuit breaker 34 includes a contact for electrically connecting the connecting portion 25 and the AC power supply AC1 and a movable element for opening and closing the contact. When the predetermined condition is satisfied, the circuit breaker 34 operates the mover to open the contact point, thereby interrupting the pair of electric circuits L1 that connect the connection unit 25 and the AC power supply AC1. The pair of electric paths L1 is a power supply path from the AC power supply AC1 to the connection unit 25.

  In this embodiment, the circuit breaker 34 is an earth leakage breaker. The circuit breaker 34 is configured to detect an unbalance of the current flowing through the electric wire passing through the zero-phase-sequence current transformer (ZCT) 341. And the circuit breaker 34 will interrupt | block a pair of electric circuit L1, if the imbalance of the electric current accompanying a leak is detected.

  Moreover, the circuit breaker 34 may be comprised so that a pair of electric circuit L1 may be interrupted | blocked, if an overcurrent and a short circuit are detected besides an electric leakage. This configuration can be realized by providing an overcurrent tripping device. In addition, the circuit breaker 34 may be configured to interrupt the pair of electric circuits L1 when the tracking phenomenon is detected. This configuration can be realized by providing an electrode for detecting a current generated by the occurrence of the tracking phenomenon between the first blade receiving portion 251 and the second blade receiving portion 252.

  As illustrated in FIG. 1A, the ground terminal 35 is provided so as to protrude forward from one surface (front surface) of the cover 33. As shown in FIG. 5, the ground terminal 35 is electrically connected to the ground E1 through terminals T5, T8, and T9 described later. The ground terminal 35 is a terminal for connecting the ground line P2 (see FIG. 6). The ground line P2 is connected to a device to be used together with a two-pole plug (so-called 2P plug) P1 having a pair of voltage electrode plug blades. As shown in FIG. 6, when the two-pole plug P1 is connected to the outlet block 2, the ground line P2 is electrically connected to the ground E1 by connecting the ground line P2 to the ground terminal 35.

  As shown in FIG. 1A, the test switch 36 is a push button provided in a form embedded in the cover 33. The test switch 36 is used to test the operation of the circuit breaker 34. The circuit breaker 34 is configured such that when the test switch 36 is operated, a pseudo current of a leakage current flows through an electric wire passing through the zero-phase current transformer 341. For this reason, if the circuit breaker 34 interrupts the pair of electric circuits L1 when the user (for example, a contractor) operates the test switch 36, the user may confirm that the circuit breaker 34 is operating normally. it can.

As shown in FIG. 2, the handle 37 includes a handle body 370, a bearing 371, and a rotating shaft 372. The handle body 370 is made of, for example, a resin material.
The bearing 371 is formed integrally with the handle body 370, and the rotation shaft 372 is inserted therethrough. The rotating shaft 372 is attached to the housing 31 in a state of being inserted into the bearing 371.

  The handle 37 is mechanically connected to the mover of the circuit breaker 34, and is configured to interlock with the mover. As shown in FIG. 2, the handle 37 is configured to rotate about the rotation shaft 372 between the on position and the off position in conjunction with opening and closing of the circuit breaker 34.

  In the on position, as shown in FIG. 1A, only an exposed surface 373 and a convex portion 374 of the handle 37 described later are exposed from the opening 331, and other portions of the handle 37 are accommodated inside the housing 31. Yes. That is, when the handle 37 is in the on position, the user can touch only the exposed surface 373 and the convex portion 374. In the off position, as shown in FIG. 1B, the handle body 370 is at a position rotated by a predetermined angle about the rotation shaft 372 from the on position. That is, most of the handle 37 is exposed from the opening 331 when the handle 37 is in the off position.

  In the present embodiment, the handle 37 rotates from the on position to the off position when the circuit breaker 34 opens the contact point and interrupts the pair of electric circuits L1. Specifically, when the circuit breaker 34 operates the mover to open the contact, the handle 37 rotates from the on position to the off position in conjunction with the mover. And the handle | steering-wheel 37 is latched in an OFF position by interlocking with the needle | mover of the circuit breaker 34. FIG. Further, the handle 37 rotates from the off position to the on position by being given a predetermined rotational force at the off position. Specifically, when the user manually operates the handle 37 and the handle 37 rotates from the off position to the on position, the mover of the circuit breaker 34 operates in conjunction with the handle 37, The contact is closed.

  The handle main body 370 includes an exposed surface 373 and a convex portion 374. As shown in FIGS. 1A and 2, the exposed surface 373 is exposed from the opening 331 at the on position of the handle 37. Further, the exposed surface 373 is substantially flush with one surface (that is, the front surface of the cover 33) provided with the opening 331 in the housing 31 at the on position of the handle 37.

  The convex part 374 protrudes from the exposed surface 373 as shown in FIGS. 1A and 2. Specifically, the convex portion 374 protrudes obliquely downward from the lower end edge of the exposed surface 373. That is, the convex portion 374 protrudes from the end edge (here, the lower end edge) of the exposed surface 373 farthest from the rotation shaft 372.

  The convex portion 374 has an inclined surface 375. The inclined surface 375 is inclined with respect to the exposed surface 373 and is configured to receive a rotational force F1 for rotating the handle 37 from the on position to the off position. Here, the rotational force F <b> 1 is a force in a direction parallel to the tangent of the arcuate track of the handle body 370 with the rotation shaft 372 as the center.

  In the present embodiment, the inclined surface 375 is a surface that is almost orthogonal to the rotational force F <b> 1 when the handle 37 is on. Of course, the inclined surface 375 does not have to be orthogonal to the rotational force F1 at the on position of the handle 37, and may be any surface that can receive the rotational force F1.

In the present embodiment, the breaker block 3 includes five terminals T1 to T5 as shown in FIG. The outlet block 2 includes four terminals T6 to T9 as shown in FIG. Each of the terminals T1 to T9 is composed of, for example, a quick connection terminal. As shown in FIG. 4, in the body 22 of the outlet block 2, insertion holes 221 to 224 for inserting electric wires are provided at positions corresponding to the terminals T6 to T9. Moreover, as shown in FIG. 4, in the body 32 of the breaker block 3, insertion holes 321 to 325 for inserting electric wires are provided at positions corresponding to the terminals T1 to T5.

  As shown in FIG. 5, the terminals T1 and T2 are each electrically connected to an AC power supply AC1. That is, the terminals T1 and T2 are input terminals used to electrically connect the breaker block 3 to the AC power supply AC1. Terminals T3 and T4 are output terminals for outputting an AC output from the AC power supply AC1. The terminal T5 is electrically connected to the ground terminal 35.

  The terminal T6 is electrically connected to the terminal T3 of the breaker block 3 via the electric wire C1 (see FIG. 4). The terminal T7 is electrically connected to the terminal T4 of the breaker block 3 via the electric wire C2 (see FIG. 4). That is, the terminals T6 and T7 are input terminals that are electrically connected to the output terminals (terminals T3 and T4) of the breaker block 3. The terminal T8 is a terminal for electrically connecting to the ground E1, and is electrically connected to the ground E1 via an electric wire. The terminal T9 is electrically connected to the terminal T5 of the breaker block 3 via the electric wire C3 (see FIG. 4). Therefore, the ground terminal 35 of the breaker block 3 is electrically connected to the ground E1 via the terminals T5, T8, and T9.

  The terminals T6 and T7 are electrically connected to the first blade receiving portion 251 and the second blade receiving portion 252 of the connecting portion 25, respectively. For this reason, the 1st blade receiving part 251 and the 2nd blade receiving part 252 are electrically connected with AC power supply AC1 via terminal T1, T2, T3, T4, T6, T7. Therefore, by connecting the plug of the device to be used to the outlet block 2, power can be supplied from the AC power supply AC1 to the device. Further, the terminal T8 is electrically connected to the third blade receiving portion 253. Therefore, by connecting the plug of the device to be used to the outlet block 2, the ground terminal of the device is electrically connected to the ground E1.

  Hereinafter, operation | movement of the connection apparatus 1 of this embodiment is demonstrated. The connection device 1 of the present embodiment is used in a state where the handle 37 is in the on position during normal times when no abnormality such as leakage occurs. In normal times, when the plug of the device to be used is connected to the outlet block 2, power can be supplied from the AC power supply AC1 to the device. Here, for example, when a leakage occurs, the circuit breaker 34 operates to interrupt the pair of electric circuits L1. For this reason, at the time of abnormality, electric power is not supplied to apparatus from AC power supply AC1. At this time, the handle 37 rotates from the on position to the off position in conjunction with the operation in which the circuit breaker 34 interrupts the pair of electric paths L1.

  Thereafter, the handle 37 is latched in the off position until the user manually turns on the handle 37. The on operation refers to an operation of applying a rotational force necessary for the handle 37 to move from the off position to the on position. After eliminating the abnormality, the user manually turns on the handle 37 at an arbitrary timing, so that the handle 37 moves to the on position. Along with the movement of the handle 37 to the on position, the breaker 34 releases the break, whereby the pair of electric paths L1 become conductive again. For this reason, electric power can be supplied from the AC power supply AC1 to the device.

  Unlike the connection device in which the user cannot manually turn off the handle 37, the connection device 1 of this embodiment allows the user to manually turn off the handle 37 even when the handle 37 is in the on position. Is possible. The off operation refers to an operation for applying a rotational force necessary for the handle 37 to move from the on position to the off position.

That is, in the connection device 1 of the present embodiment, when the handle 37 is in the on position, the user hooks the fingernail on the inclined surface 375 of the convex portion 374 and gives the handle 37 a rotational force F1, thereby 37 can be manually rotated from the on position to the off position. In addition, the user can apply the rotational force F <b> 1 to the handle 37 by hooking the tip of the tool S <b> 1 (see FIG. 9) such as a flat-blade screwdriver on the inclined surface 375 of the convex portion 374. As described above, the connection device 1 according to the present embodiment includes the convex portion 374 and allows the user to manually turn off the handle 37.

  Here, when allowing the user to manually turn off the handle, the appearance of the connecting device may be deteriorated by exposing the handle from the opening so that the user can easily turn off the handle. For example, a connection device in which the convex portion 374 does not have the inclined surface 375 will be described as an example. In this connection device, when the user manually turns off the handle 37, the user needs to apply the rotational force F <b> 1 to the handle 37 while picking the convex portion 374 or pressing the belly of the finger against the convex portion 374. is there. For this reason, it is necessary to increase the protruding amount of the convex portion 374 so that the user can easily pick the convex portion 374 or the user can press the belly of the finger against the convex portion 374. The protruding amount refers to an amount (length in the front-rear direction) in which the convex portion 374 protrudes from the opening 331 when the handle 37 is in the on position. And if the protrusion amount of the convex part 374 becomes large, since the convex part 374 is conspicuous, the appearance of a connection apparatus may worsen.

  On the other hand, in the connection device 1 of the present embodiment, it is easy to apply the rotational force F1 to the handle 37 as long as even the fingernail or the tip of the tool S1 can be hooked on the inclined surface 375. For this reason, in the connection apparatus 1 of this embodiment, the protrusion amount of the convex part 374 can be suppressed, ensuring the ease of manual OFF operation of the handle | steering-wheel 37. FIG. That is, the connecting device 1 of the present embodiment is less likely to deteriorate in appearance as compared with a connecting device in which the convex portion 374 does not have the inclined surface 375. Further, in the connection device 1 according to the present embodiment, the exposed surface 373 is substantially flush with the front surface of the cover 33 when the handle 37 is in the off position, so that the handle 37 is not noticeable.

  As described above, in the connection device 1 of this embodiment, the handle 37 includes the convex portion 374 that protrudes from the exposed surface 373 of the handle body 370. For this reason, the connection device 1 of the present embodiment allows the user to manually turn off the handle 37. The convex portion 374 is inclined with respect to the exposed surface 373 and has an inclined surface 375 that receives the rotational force F1. For this reason, the connection apparatus 1 of this embodiment can suppress the protrusion amount of the convex part 374, accept | permitting manual OFF operation of the handle | steering-wheel 37, and does not become bad appearance.

  The connection device 1 of the present embodiment does not actively recommend that the user manually turns off the handle 37. The connection device 1 according to the present embodiment includes the inclined surface 375 on the convex portion 374, thereby preventing the handle 37 from being erroneously turned off unintentionally by the user. That is, in the connection device 1 of the present embodiment, the protruding portion 374 includes the inclined surface 375 as described above, thereby suppressing the protruding amount of the protruding portion 374. For this reason, in the connection apparatus 1 of this embodiment, since a user's leg | foot and the head of a cleaner are hard to be hooked on the convex part 374, the situation where the rotational force F1 is given to the handle | steering wheel 37 unintentionally does not occur easily.

  In particular, the inclined surface 375 is preferably provided so as not to be seen from the vertical direction of one surface (that is, the front surface of the cover 33) where the opening 331 of the housing 31 is provided when the handle 37 is in the on position. In this configuration, unless the user intentionally turns off the handle 37 with a fingernail or the tip of the tool S1, it is difficult for an external force to be applied to the inclined surface 375, and the handle 37 is less likely to be turned off accidentally.

Here, the exposed surface 373 does not have to be flush with the one surface (that is, the front surface of the cover 33) where the opening 331 of the housing 31 is provided in the on position of the handle 37, and if it is substantially flush. Good. For example, in the ON position of the handle 37, the height α between the exposed surface 373 in the front-rear direction and the front surface of the cover 33, and the height between one end (front end) of the convex portion 374 and the front surface of the cover 33 in the front-rear direction. It is only necessary that β satisfies the relationship of α ≧ 0 and β> 0. The height α is a positive value if the exposed surface 373 is behind the front surface of the cover 33, and a negative value if the exposed surface 373 is the front. Further, the height β is a positive value if one end of the convex portion 374 is in front of the front surface of the cover 33, and a negative value if it is rearward. That is, the exposed surface 373 may be positioned behind the front surface of the cover 33 as long as the convex portion 374 protrudes forward from the front surface of the cover 33 at the on position of the handle 37.

  Furthermore, as shown in FIG. 6, when using the connection apparatus 1 of this embodiment in the state attached to wall A1, the outlet block 2 and the breaker block 3 are arrange | positioned along with the perpendicular direction (up-down direction). ing. In the present embodiment, the breaker block 3 is disposed below the outlet block 2. This configuration is particularly suitable when the two-pole plug P1 is connected to the outlet block 2. That is, when the two-pole plug P1 is connected to the outlet block 2, the ground wire P2 is connected to the ground terminal 35. Even if the ground wire P2 is dropped from the ground terminal 35 during the construction, the ground wire P2 is 2 It is difficult to contact the plug blade of the pole plug P1. Therefore, this structure can improve the safety of construction.

  The ground terminal 35 provided on the same surface side as the handle 37 of the breaker block 3 is preferably located between the connecting portion 25 and the handle 37.
