Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electric device, and more particularly, to an electric device having a concent plug for visually displaying an operating state of the electric device.

[0002]

[Prior art]

 In general, many electric devices connect an outlet plug to an outlet to which AC power is supplied, and operate with the power supplied from this. In such electrical equipment, if one electrical equipment is connected to the outlet, no problem will occur, but if the outlet plugs of multiple electrical equipments are connected to the outlet, it often happens. Sometimes I couldn't figure out which electrical device was compatible with the outlet plug.

Especially when a large number of electric devices are used in a temporary state, it is often difficult to perform one-layer discrimination because power supply and signal cables are complicated and they are often connected to outlets through various routes. In such a situation, if you accidentally pull out the outlet plug of one electric device and pull out the outlet plug of another electric device that is in operation, it may stop working and cause a serious failure. Therefore, the worker had to be careful enough to pull out the outlet plug.

[0004]

[Problems to be solved by the device]

 However, even with such sufficient attention, it is not possible to determine from the outlet plug whether or not the electric device is in operation, so it is often the case that the plug other than the desired electronic device is pulled out, and the troubles associated therewith are completely eliminated. I couldn't avoid it. In particular, many electric devices in recent years store settings and data in volatile semiconductor memory.If the power is turned off without saving the data, the settings and data will be lost and it will take a lot of time to recover. May be required.

The present invention solves the above-mentioned drawbacks of the prior art, and makes it possible to confirm whether or not an electric device is in operation by using a plug, so that the outlet plug of the electric device in operation can be checked. It is an object of the present invention to provide an electric device equipped with a contact plug with an operating indicator that can prevent accidental pulling out.

Note that the term “electrical device” used in this specification includes electronic devices such as communication devices, information devices, or power supply devices.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention is such that an electric device 8 connected to a power source through an outlet plug 7 and operated by this power source emits light when the electric device 8 is in operation. Side, a light emitting means 3 provided on the side, an optical fiber cable 5 for guiding the light emitted by the light emitting means 3, and an emitting end 6 provided on the side of the outlet plug 7 for outputting the light guided by the optical fiber cable 5. Have.

[0008]

[Action]

 According to the present invention, when the electric device 8 is in operation, a current is supplied to the light emitting means 3, which emits light. The light of the light emitting means 3 is guided to the optical fiber cable 5 and emitted from the emission end 6 provided on the outlet plug 7 side to the outside.

【Example】

 Next, an embodiment of an electric device having an outlet plug with an operating indicator according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a schematic view showing an embodiment of an electric device having an outlet plug with an operating indicator according to the present invention. It should be noted that, in order to facilitate understanding of the present invention, constituent elements directly related to the present invention are shown in the figure, and an internal circuit of the electric device 8 which is not directly related to the present invention is not shown for brevity.

The connector 1 is a connector provided on the electric device side and is connected to the connector 2 on the power cable side. The connector 1 is also provided with a light emitting element 3 having a relatively high brightness such as a light emitting diode. The light emitting element 3 is an element that emits light when a current is supplied from the electric device 8 when the electric device 8 is in operation, and is arranged at a position facing the optical fiber cable 5 built in the connector 2.

The optical fiber cable 5 is built in these through the connector 2 and the power supply cable 4, and is connected to the emission end 6 attached to the outlet plug 7. The exit end 6 is the exit end of the optical fiber cable, and a diffusing lens or the like is attached in order to widen the exit angle of light and enhance the visibility. The emitting end 6 is also provided on the back surface of the outlet plug 7 as shown in FIG. 1 so that the light emitted from the outlet plug 7 can be easily recognized when the outlet plug 7 is inserted into an outlet (not shown). ing. The outlet plug 7 is, for example, an outlet that is plugged into the outlet of an AC 100V or AC 200V power source, and supplies electric power to the electric device 8 via the power cable 4.

In the present embodiment, when the outlet plug 7 is inserted into the outlet and the operation switch (not shown) of the electric device 8 is turned on, a current is supplied to the light emitting element 3 to light it. Since the light emitting element 3 to the diffuser lens at the emitting end 6 are optically connected by the optical fiber 5, the light of the light emitting element 3 is emitted to the outside from the diffuser lens at the emitting end 6 of the fiber cable 5. .

As described above, according to the present embodiment, the technology such as a lighting device for a gastric camera and a lighting device for guiding sun rays to the basement are separated by using the optical fiber cable to separate the light emitting portion and the light emitting portion. However, it is possible to provide a reliable operating indicator on the outlet plug.

It should be noted that the embodiments described here are for explaining the present invention, and the present invention is not necessarily limited to this, and a person skilled in the art can do without departing from the spirit of the present invention. Such variations and modifications are included in the scope of the present invention. In other words, the present invention is one in which a light emitting element is caused to emit light according to the operating state of an electric device and this light is guided to an outlet plug by an optical fiber cable, and a technique similar to this is included in the scope of the present invention. .

[0016]

[Effect of device]

 As described above, according to the present invention, when the worker pulls out the outlet plug 7, whether the electric device 8 connected to the outlet plug 7 is currently in operation by the light of the diffusing lens provided on the plug 7 You can judge. Therefore, it is possible to prevent the outlet plug of the operating electric device from being accidentally pulled out. Further, according to the present invention, since the electric circuit for controlling the lighting of the light emitting element 3 is provided inside the electric device, noise is not received from the outside and unnecessary radiation is not emitted to the outside.
