Abstract

(57) [Abstract] [Purpose] A current sensor is provided so that a tap suitable for an OA system can be used as an ordinary tap. [Configuration] A switching switch is provided in parallel with a switching element that functions by a current sensor, and the switching switch can switch between a tap suitable for an OA system and a normal tap. [Effect] Since one tap can be used as the OA system or as an ordinary tap, convenience in use is enhanced.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an improvement of a tap having a plurality of outlets.

[0002]

[Prior Art]

 Various taps for OA devices have been proposed due to the spread of OA devices in recent years, but most of them have a current sensor installed in any one of a plurality of outlets, and the sensor detects the current. It is sometimes convenient to use as a power supply tap for an OA system in order to prevent forgetting to turn off the power, as it is the one that powers other outlets.

[0003]

[Problems to be solved by the device]

 The conventional tap described above is good when a plurality of devices are used together in one system, but when a plurality of devices are used separately, the action of the sensor described above is a drawback. That is, a specific outlet can be used freely, but other outlets whose energization is controlled by the action of the sensor are turned on and off of the equipment connected to the specific outlet, so only other outlets can be used. It cannot be used.

[0004]

[Means for Solving the Problems]

 The present invention solves such a problem, and a changeover switch is provided so that it can be used for an OA system or an electric device used alone.

[0005]

[Action]

 By changing over with the above-mentioned changeover switch, it changes into a tap suitable for an OA system and a tap suitable for an electric device used alone.

【Example】

Example 1. FIG. 1 shows an embodiment of the present invention, in which C ₁ , C ₂ and C ₃ are outlets forming a tap 1 and 2 is a current sensor connected in series with one specific outlet C ₁ as a current sensor. Relays 3 and ₃ are normally open contacts of the current relay 2 provided between the outlets C ₁ and C ₂ and C _3, and 4 is a changeover switch connected in parallel with the normally open contact. To switch between a normal tap and a tap suitable for the OA system. The plug to which AC100V is input is omitted.

First, a case of using as a tap suitable for an OA system will be described. The switch 4 is left in the illustrated state. By the way, in the OA system, for example, a personal computer main body is mainly connected to a floppy disk, a printer and the like. Therefore, the main body of the computer is the outlet C which is the master outlet.₁ To outlet C as a slave outlet₂ , C₃ Connect the above disks and printers to. By connecting in this way, when the power switch of the personal computer is turned on, the current relay 2 is energized, the contact 3 is closed, and the outlet C ₂ , C₃ The disks and printers connected to are also energized. When the power supply to the personal computer, disk, and printer is turned off after the work is completed, if the power switch of the personal computer is turned off, no current will flow to the current relay and contact 3 will return to the state shown in the figure. By outlet C₂ , C₃ Power is also turned off, and power can be turned off without operating the power switch of the disk or printer. Therefore, it is optimal when using multiple devices as a set, such as an OA system. Next, the case of using as an ordinary tap will be explained. When the switch 4 connected in parallel with the contact 3 is turned on, it becomes the same as the contact 3 being closed, and the outlet C₁ , C₂ , C₃ Can be used as independent items. Therefore, it is possible to connect devices that are not related to each other to each outlet.

FIG. 2 shows the switching state of the switch 4 by means of light emitters having different emission colors, and if 5 is a red light emitter and 6 is a blue light emitter, the tap is an OA system. When the switch 4 is in the state shown in the figure, the light emitter 5 is lit up. On the other hand, in the normal tap state, the switch 4 is ON, so that the light emitting body 6 is turned on.

FIG. 3 shows the switching state of the switch 4 by another means. For example, an illuminator 7 which is marked as ordinary for OA and is structurally divided from each other is used, and the tap is OA. When the tap is in the normal state, the portion 8 marked as OA is illuminated, and when the tap is in the ordinary state, the portion 9 marked as ordinary is illuminated.

[0010]

[Effect of the device]

 Since the present invention is configured as described above, one tap can be used in a state suitable for, for example, an OA system, or can be used as an ordinary tap by switching a switch. In addition, since the switch switching status can be visually confirmed, it is possible to visually recognize which state the tap is in. In the embodiment, the normally open contact has a contact, but it goes without saying that it can be made non-contact. Also, a semiconductor can be used instead of the current relay.
