Description

{Multi-tap Having Button with Current Display Function}

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 button 21 mounted on the mounting groove 25 of the switch housing 24 And a small power bulb 22 attached to the cap 22 is lit. As an example, a multi-tap in which a main switch is included in a drawing 1 of Patent No. 10-1407104 is disclosed.

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.

Registration No. 10-1407104 (published on June 13, 2014)

FIG. 2 is a plan view schematically showing an appearance according to various current display forms of a multi-tap having a button having a current display function according to one embodiment of the present invention. FIG. 3 is a cross- FIG. 4 is a block diagram of a multi-tap control unit including a button having a current display function according to one embodiment of the present invention. An embodiment of the present invention will be described in detail with reference to FIGS. 2 to 3. FIG.

First, referring to FIG. 2 (a), an appearance form according to various embodiments of the multi-tab of the present invention is shown. According to the present invention, a multi-tap having a button having a current display function according to the present invention includes a main body 100 and a main rocker switch unit 200.

The main body 100 is provided with at least one socket 102 so that the socket 102 can insert the plug. The structure and shape of the socket 102 may be variously modified depending on the shape of the plug. The shape may also be changed depending on the voltage used.

The main rocker switch unit 200 is formed at one end of the main body 100 and controls on / off the main terminals formed on the socket 102 at the same time. An auxiliary switch 104 may be provided for each socket 102 for safety so that the terminal of each socket 102 can be separately controlled when the main rocker switch unit 200 is turned on.

The main rocker switch unit 200 includes a push button 210, a display unit 220, a control unit 230, and a switch housing 240, do.

The push button 210 is provided to be exposed to the outer surface of the main body 100 and turns on / off the switch terminal 252 connected to the main terminal by the pressing operation of the user's finger, A transparent window is formed.

The display unit 220 is installed on the rear side of the transparent window of the push button 210 and displays a predetermined content according to a control command to the control unit 230. The displayed contents include the current current size, The calculated current power, the magnitude of the current voltage, the magnitude of the current temperature, and the like can be displayed in various forms.

The controller 230 measures the current flowing into the terminal by the current sensor 232 and displays the magnitude of the current and / or the magnitude of the power calculated by the measured current on the display unit 220 in real time. The present invention is configured to display the magnitude of the current and / or the power. Hereinafter, the function of displaying the magnitude of the current will be mainly described. However, Alternatively, or in combination.

4, the controller 230 senses a current flowing into the current sensor 232, converts the current into a digital signal through an A / D converter 234, and outputs the current signal through a signal processor 236 The size of the current and / or the magnitude of the current power calculated according to the magnitude of the current current may be displayed in the form of a decimal character or other form and displayed on the display unit 220.

The switch housing 240 includes a push button 210, a display unit 220 and a control unit 230 which are stacked in order and one end of the switch terminal 252 is exposed to the outside so that the one end of the switch terminal 252 can be connected to the main terminal. And the push button 210 is freely turned on and off by the user's hand in the switch housing 240. [

According to this embodiment, since the present invention measures the current generated at the terminal of the multi-tap and displays it through the display unit 220 mounted on the back surface of the push button 210, the user can check it at any time. Therefore, the user can check the current amount (electricity usage) displayed on the multi-tap in real time, so that the user can use the electricity only within the allowable current range of the multi-tap, thereby preventing the overload of the multi- The waste of electric power can be remarkably reduced.

In addition, according to the multi-tab according to the present invention, the display unit 220 is mounted on the back surface of the push button 210 so that the display contents of the display unit 220 are displayed externally through the transparent window of the push button 210 Therefore, the present invention can be easily applied to the switch portion of the multi-tap of the type shown in FIG. 1, so that the conventional simple design element is intact and the current consumption . ≪ / RTI >

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 display unit 220 may display the magnitude of the current measured by the current sensor 232 in the form of a numerical value or a bar graph. As shown in FIG. 2 (a), various display devices such as a seven-segment (FND), an LCD, and an LED may be used in the case of a numerical value display. As shown in FIGS. 2 (b) and 2 (c), a display device such as an LED or an LCD may be used in the form of a bar graph (or bar). In this case, the shape of the bar may be formed either in the longitudinal direction or in the lateral direction. The length of the rod varies depending on the length of the rod. The length of the rod before the current value exceeds the reference current is displayed in a normal green or blue color. The rod is displayed in red from a length exceeding the reference current, The display device may be configured to display different colors depending on the display mode.

The display of the magnitude of the current by the numerical value or the bar graph of the display unit 220 is not limited to this, and may be variously displayed by characters such as high, middle, and low as shown in FIG. 2 (d) It should also be considered that the indication of the current magnitude is included in the scope of the present invention.

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 controller 230 measures a current temperature of the terminal, and can alarm in real time through the display unit or by sound when the current temperature becomes the reference temperature or more. FIG. 5 shows a state in which electrode terminals of a brass material are connected in parallel as an internal structure of a general multi-tap. The electrode terminal of the brass component (brass color) is connected in parallel with the plug socket of the socket. As the current used increases, the temperature of the electrode terminal also rises.

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 push button 210, unexpected electric accident can be drastically reduced.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. 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.
