Description

  The present invention relates to an outlet with a blocking function for electrically connecting an existing outlet to an electric device.

  Electrical equipment has the potential for fire and electric shock accidents that occur as a result of natural disasters such as earthquakes and floods. When used in ordinary households, consumers are not always familiar with electrical knowledge. Therefore, it is not possible to pay attention to these dangers, which may lead to an unexpected accident. In addition, since it is difficult to predict when natural disasters occur, it is often difficult to take action.

  Therefore, a sensor unit that transmits earthquake information sensed by a sensor wirelessly to an outlet and shuts off electricity and energization at the outlet receiving the earthquake information is known (for example, see Patent Document 1). Further, there is known a seismic isolation outlet that is attached to the back side of a wall outlet and interrupts an electric circuit when a sphere exceeds a convex portion by an earthquake (see, for example, Patent Document 2).

An opening 62a is formed at the lower end of the main body 62, and water can flow from the opening 62a toward the float 5 side. Further, a shield 62b is provided above the float 5 so as to prevent water flowing into the float 5 from flowing upward. Further, two mounting bolts 63 are attached to the main body 62 in the vertical direction, and the casing 6 can be attached to the existing outlet 100 using the mounting bolts 63 as will be described later.

  Next, the installation method and operation of the outlet 1 with a blocking function having such a configuration will be described.

  First, as shown in FIG. 7, the panel 101 of the existing outlet 100 is removed, and the plug 11 of the outlet 1 with the blocking function is inserted into the plug receiving portion 103 provided in the main body 102 of the existing outlet 100. Here, the existing outlet 100 is disposed on a vertical member such as a wall or pillar of a house and connected to a commercial power source. Next, the outlet 1 with a blocking function is attached to the existing outlet 100 by tightening the attachment bolt 63 in the screw hole 103 a provided in the main body 102. Here, without removing the panel 101, the plug 11 of the outlet 1 with the blocking function may be inserted into the plug receiving portion 103 from above the panel 101.

  Subsequently, when a plug for a power cable of an electric device such as a TV or a vacuum cleaner is attached to the plug receiving portion 12 of the outlet 1 with a shut-off function, and the operation bar 43 is pressed once and released, the weight 3 as described above. Is disposed on the base 31. In this state, as shown in FIG. 1, the switch bar 2 is located at the bottom dead center, the detection relay 7 is turned off, the connection switch 13 is turned on, and the plug 11 and the plug receiver 12 are connected. It is in the state. In other words, the existing outlet 100 and the electric device are energized via the plug 11 and the plug receiver 12.

  In this state, when a predetermined vibration is applied to the outlet 1 with a blocking function due to an earthquake, an infant's contact or mischief, the weight 3 is detached from the pedestal 31 as shown in FIG. Accordingly, as described above, the switch bar 2 slides to the top dead center by the force of the compression coil spring 23, the detection relay 7 is turned on, and the connection switch 13 is turned off. That is, the connection between the insertion plug 11 and the plug receiving portion 12 is released, and the energization between the existing outlet 100 and the electric device is interrupted.

  Similarly, as shown in FIG. 8, when the float 5 is submerged to a predetermined position with drainage or rainwater from a drainage facility, the switch bar 2 and the weight 3 are pushed up as described above, and the weight 3 is detached from the pedestal 31. . Thereby, the connection between the plug 11 and the plug receiving portion 12 is released, and the energization between the existing outlet 100 and the electric device is interrupted.

  Thereafter, after confirming safety, when the operation bar 43 is once pushed and released, the weight 3 is returned to the base 31 as described above, whereby the switch bar 2 is located at the bottom dead center and the detection relay 7 is turned off. The connection switch 13 is turned on. And the plug 11 and the plug receiving part 12 are reconnected, and the energized state of the existing outlet 100 and the electric equipment is restored.

  As described above, according to the outlet 1 with the shut-off function, when vibration or flooding occurs, the energization between the existing outlet 100 and the electric device is shut off, thereby reliably preventing a fire or an electric shock. It becomes possible. In addition, once the energization is interrupted, the weight 3 does not return to the upper end of the switch bar 2 unless the reset mechanism 4 is operated, that is, the energization is not restored, and thus energization is inadvertently restored. Is prevented / suppressed.

  Also, since the plug 11 and the plug receiving portion 12 are connected and separated by turning the connection switch 13 on and off with the switch bar 2, once the connection switch 13 is turned on, the plug 11 and the plug receiving portion are connected. The energization state with the part 12 is stable. That is, unlike the conventional case, since the connection state is not maintained by the weight of the sphere, even if the weight 3 is shaken on the pedestal 31 due to vibration, the energization state is not affected, and a stable energization state is achieved. can get.

  Furthermore, since the upper cover part 61 of the casing 6 is transparent, the position state of the weight 3 can be confirmed from the outside. For this reason, if the weight 3 is removed from the pedestal 31 except for the upper lid 61 when the electric device does not operate, it can be determined that the energization is cut off by the outlet 1 with the blocking function. If it is disposed, it can be determined that a power failure of the commercial power source or a failure of the electrical equipment itself has occurred.

  Moreover, since it is only necessary to insert the plug 11 of the outlet 1 with a blocking function into the plug receptacle 103 of the existing outlet 100, even a consumer who is not familiar with electricity knowledge can easily handle it. Moreover, since no power source, power, or radio is required, it can be used anywhere and anytime. Further, since the power supply is easily restored by simply pressing the operation bar 43, the handling is extremely easy and safe.

  Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above embodiment, and even if there is a design change or the like without departing from the gist of the present invention, Included in the invention. For example, in the above embodiment, the connection switch 13 is turned on / off via the detection relay 7, but the connection switch 13 may be directly turned on / off by the switch unit 22.
