JPH1064627A - Power cord device - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain a power cord device with its high reliability capable of being easily identified by permitting a luminescent element to go out when a power supply side connection plug slips off from a connection device. SOLUTION: Luminescent elements 3, 3A are lit when a power cord device is connected, and the luminescent elements 3, 3A go out by opening a switch device 4 or a switch device 4A. If a power supply side connection plug 6 slips off from a connection device 7 or is removed, the luminescent elements 3, 3A go out similarly. Thus, operational safety of the power cord device can be improved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power cord device used for connecting a personal computer, OA equipment, and household electric appliances.

[0002]

2. Description of the Related Art In a conventional power cord device, when a large number of power cords are connected to a connection device such as a tap or an outlet, to remove a target power cord, each power cord is visually traced and confirmed. I had to.

[0003]

In the prior art, when the number of power cords is large, or when there is an obstacle on the way and it is impossible to track the power cord, it is necessary to disconnect the power cord and check. . According to the present invention, a required power cord can be distinguished by turning on or off a light emitting element such as a lamp, so that the power cord is not accidentally unplugged or easily identified even when the power is disconnected. It is an object of the present invention to provide a power cord device capable of performing the above-described operations.

[0004]

According to the power cord apparatus of the present invention, a first power source is turned on by an induced voltage applied to a main circuit.
, A first switch connected in series with the first light emitting element to open and close a lighting circuit of the light emitting element, a first switch, the first light emitting element, and a main circuit. A connection device, a power supply side connection plug fitted and connected to the connection device, a device side connection plug for connecting the power side connection plug and the load device via a connection cord, and a second device attached to the device side connection plug. A second light-emitting element connected in series with the first light-emitting element and turned on by an induced voltage applied to the main circuit; and a second light-emitting element attached to the device-side connection plug and connected in series with the second light-emitting element. And a second switch for opening and closing the lighting circuit.

[0005]

Next, an embodiment of a power cord device according to the present invention will be described. In FIG. 1, the light emitting element 3 is a device that uses, for example, an LED (light emitting diode) or the like, and is turned on by an induced voltage applied to a main circuit. The switch 4 is a device that uses a push button switch or the like and is connected in series with the light emitting element 3 to open and close a lighting circuit of the light emitting element 3 as shown in FIG.

[0006] The connection device 7 is, for example, a tap or an outlet, and includes a switch 4, the light emitting element 3, and a main circuit. The power supply side connection plug 6 is, for example, a plug or the like, and is fitted and connected to the connection device 7 via the main circuit terminal 6A. The device side connection plug 5 is a plug or the like provided on the device side, and is a device for connecting the power supply side connection plug 6 and the load device via the connection cord 8.

The light-emitting element 3A is an illuminating device attached to the device-side connection plug 5 and connected in series with the light-emitting element 3 and turned on by an induced voltage applied to the main circuit. Is a device for opening and closing a lighting circuit of the light emitting elements 3 and 3A connected in series with the light emitting element 3A.

FIG. 2 is a side view of the power supply side connection plug 6, which is provided with an auxiliary circuit terminal 6B for connecting to the series circuit of the switch 4 and the light emitting element 3 of the connection device 7. FIG. 3 is a front view of FIG.

Since the present embodiment is constructed as described above, when the power cord device is connected, the light emitting elements 3, 3
A is on, and the light emitting elements 3, 3A are turned off by opening the switching device 4 or the switching device 4A. Also, when the power supply side connection plug 6 is disconnected from the connection device 7 or is removed, the light emitting elements 3 and 3A are similarly turned off.

As described above, the switching device 4 or the switching device 4
By opening A, the connection state between the power supply side connection plug 6 and the connection device 7 can be determined, so that it is possible to eliminate the error that the power supply side connection plug 6 is accidentally pulled out. Also, when the power supply side connection plug 6 is disconnected from or removed from the connection device 7, the light emitting elements 3, 3A are similarly turned off.
It can be easily identified.

It goes without saying that the present invention can be applied to all devices having a power cord.

[0012]

According to the present invention, the operational safety of the power cord device can be improved.
