Abstract
The present invention relates to a multi-tap having a switch button including a current display function, and more particularly, to a multi-tap including a main body having one or more sockets and a main locker for on / off control of terminals formed on one end of the main body, Wherein the main rocker switch unit comprises: a push button provided to be exposed to an outer surface of the main body and to be turned on / off by a pressing operation of the user's finger and having a transparent window formed on the surface pressed by the finger; A display unit provided on a back surface of the transparent window of the push button, and a current sensor for measuring a current flowing into the terminal by a current sensor and displaying the measured current on the display unit in real time. And a switch housing for accommodating the push button, the display unit, and the control unit.

Description
The present invention relates to a multi-tap, and more particularly to a multi-tap having a switch button including a current display function.
1, the conventional multi-tap has a structure in which the main power switch 20 blocks all the positive electrodes, and when the switch is turned on, the
Generally, most of the multi-taps are designed to operate safely at a maximum of 16A or less. However, since the amount of electricity actually used is not displayed outside, the user can not know whether the current state is below 16A. Accordingly, the current consumption of the electronic devices connected to the multi-tap can not be grasped and the current is overused. As a result, various accidents such as fire caused by the overload cause damage to human life and property.
Even if the electric device is not actually used, even if the electric cord is plugged into the outlet, each electric device consumes minute quiescent current, which is a main cause of electric waste.
In addition, most of the products having a quiescent current shutdown function are expensive, or the quiescent power shutdown function can be used only in computer peripherals, which hinders efforts to spread the quiescent current across the country. The standby current interruption function is a structure in which peripheral devices are connected to a relay output terminal when the main computer is turned off, so that the life of the electric device is shortened due to frequent on / off operations.
The object of the present invention is to provide a multi-tab provided with a button having a current display function in the main body.
Another object of the present invention is to provide a multi-tap including a button having a current display function capable of alarming in real time through the display unit or by sound when the control unit measures the current temperature of the terminal and the current temperature becomes the reference temperature or more will be.
Other objects of the present invention can be achieved by the detailed description of the present invention described with reference to the accompanying drawings.
In order to achieve the above object, a multi-tap having a button having a current display function according to the present invention includes a main body having one or more sockets, a main body provided at one end of the main body, And a main rocker switch portion for simultaneously controlling on / off of a main terminal formed in the socket,
The main rocker switch unit includes:
A push button provided on the outer surface of the main body to turn on / off a switch terminal connected to the main terminal by a pressing operation of the user's finger, a push button having a transparent window formed on the surface pressed by the finger, A control unit attached to a back surface of the display unit to measure a current flowing into the terminal including the current sensing sensor and to display the measured current on the display unit in real time, And a control unit stacked in order, and a switch housing having one end of the switch terminal exposed to the outside so as to be connected to the main terminal.
The display unit may display at least one of the magnitude of the current and the magnitude of the current power in the form of a numerical value or a bar graph.
If the current exceeds the reference current, the controller may alarm or warn the user by a character or status change through the display unit.
The controller may measure a current temperature of the terminal and may alarm in real time through the display unit or by sound when the current temperature exceeds the reference temperature.
According to the present invention, since the amount of electricity used is displayed in real time by the display unit of the multi-tap, a part or all of the electric device is cut off before the overcurrent, Since the standby current can be visually confirmed, the user is prompted to switch off immediately, and the electric waste can be remarkably reduced.
In addition, by using the conventional button cap as a display window as it is, there is an advantage that a new function of current display can be simply added by applying minimal change to a conventional product.

According to this embodiment, since the present invention measures the current generated at the terminal of the multi-tap and displays it through the
In addition, according to the multi-tab according to the present invention, the
In addition, the conventional multi-tap as shown in Fig. 1 has a breaking characteristic, for example, the switch must be shut off within 8-10 seconds at 30A, and the switch should be shut off within 1 hour at 15A. There is a bimetallic type terminal inside the switch. Generally, the allowable current of the multi-tap is 16A maximum, so it can not be used anymore. According to the conventional multi-tap, after the terminal is detached, it is known that the allowable current value is exceeded, so that many inconveniences and electric safety remain in the blind spot. Therefore, as in the present invention, if the current consumption can be sensed in real time and the safe use of electricity can be induced, a lot of losses can be reduced.
Referring back to FIG. 2, the
The display of the magnitude of the current by the numerical value or the bar graph of the
If the current exceeds the reference current, the controller may alarm or warn the user by a character or status change through the display unit. That is, when the current use amount exceeds the reference current value, the buzzer sounds to warn the user, thereby preventing the electric accident.
In addition, in one embodiment of the present invention, the
As a problem of a conventional conventional multi-tap, a fire occurs in a flame generated between a plug terminal and an electrode terminal due to dust. Even if the current is not used a lot, the ignition is caused by dust and moisture. That is, the current alone can not prevent an electric accident. In addition, a temperature rise may occur due to contact resistance between the plug terminal and the multi-tap terminal. In addition, there may be a problem of heat generation due to the use of low-grade materials which are not covered by regulations when manufacturing terminals. When three such factors are used, namely dust, contact resistance, and bad terminals below the specification, the risk of electrical accidents increases even though the rated current is used. Therefore, as in the embodiment of the present invention, if the correlation between the current and the temperature of the electrode terminal of the multi-tap is continuously monitored through the

Various modifications may be made by those skilled in the art. It is to be understood that, although the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will not.
