Description

Desk-mounted multi-tap {desk-mounted multi-tap}

The present invention relates to a desk-mounted multi-tap, and more specifically, to supply power to various electrical and electronic devices by simply inserting and supporting it vertically into a wire hole formed on a work or study desk used in an office or residential building. This is about a desk-mounted power strip that can be used.

Due to the influence of industrialization and the development of technology, various types of electrical and electronic devices (hereinafter referred to as 'electrical and electronic devices') have become widespread. As a result, it is necessary to receive and distribute output from outlets buried in the walls of offices or residential buildings. As a means, multi-taps of various structures are used.

Most of these power strips are structured to have multiple outlets in a single casing for distributing AC power. They are mainly used on the floor indoors or outdoors, so there is a high risk of electric shock during use if there is water on the floor, but they are also used as desks for work or study. When using a computer, monitor, keyboard, mouse, modem, printer, and various electrical devices, you have no choice but to use a power strip.

However, conventionally, when using a typical multi-tap on a desk, the wires such as power lines or communication lines are not organized on the back of the desk and are often twisted and messy, and when used on the floor, connecting and disconnecting the plug is inconvenient. There is a problem, and if exposed to moisture, there is a high risk of accidents such as electric shock.

Accordingly, as an example of a desk-mounted multi-tap that can be used by supporting it in the wire hole of the desk top and to which the power plug of an electric device can be connected, Registered Patent No. 10-1373215 (Reference 1) shows that it is installed in the wire hole formed on the desk. A power strip has been suggested.

However, the multi-tap proposed in Reference 1 has a short body that protrudes from the bottom of the main body, so it is easily separated when the body of the main body is simply inserted into the wire hole of the desk, and the plurality of plug insertions are formed only on the upper surface of the main body. For cramped

When placing the PC main body on the floor to secure space on the desk top or using a fan or heater around the desk, there is the hassle of having to unnecessarily drag and connect the plug of an electrical device into the plug insertion part of the main body exposed at the top of the desk. Not only that, but if the wires of electrical devices placed on the floor are short, it is impossible to use a multi-tap and its functionality is also extremely limited.

In particular, when the conventional desk-mounted multi-tap, including Reference 1, is used by connecting the plugs of a plurality of various electrical and electronic devices, the actual total current amount of the electrical and electronic devices cannot be checked in real time, making it difficult for the user to estimate the appropriate amount of usage.

Therefore, when a plurality of electrical and electronic devices are connected to a conventional desk-mounted multi-tap and power is supplied to the electrical and electronic devices at the same time, an overcurrent breaker is installed to cut off the main power when heat is generated in excess of the maximum allowable current of the conventional desk-mounted multi-tap. However, in this configuration, in case of overheating due to exceeding the maximum allowable current, the overcurrent breaker suddenly operates without warning and cuts off the main power, which not only causes failure of the electrical and electronic devices in use, but also prevents the user from performing document work through a PC, etc. If it is impossible to deal with it, the problem of losing data arises.

In addition, if the conventional desk-mounted multi-tap is not firmly fastened and the center of gravity is not aligned while supplying power to electrical and electronic devices, and the desk-mounted multi-tap is tilted, there is an unstable problem in that the desk-mounted multi-tap is in an unstable support state.

Reference 1: Registered Patent No. 10-1373215

Therefore, in order to solve the problems of the prior art, the present invention allows the user to use the actual power of the electrical and electronic device in use by simply inserting it vertically into a wire hole formed on a work or study desk and using it in a simple mounted state.

In addition, the present invention outputs warning information so that the user can recognize when the actual power used exceeds the maximum allowable power, encouraging the user to adjust the connection and usage of electrical and electronic devices, and even after outputting the warning information, the maximum allowable power is exceeded. The purpose is to provide a desk-mounted power strip that cuts off the power if the state is maintained for a set period of time.

In addition, the present invention is a desk-mounted type that detects if the center of gravity is not aligned and tilts while supplying power to electrical and electronic devices using a desk-mounted multi-tap, and cuts off the main power supplied to the electrical and electronic devices when the tilted state is maintained for a set period of time.

A plurality of plug sockets 120 are provided in succession at equal intervals. At this time, for example, 3 to 5 plug sockets 120 may be provided at regular intervals along the longitudinal direction, that is, the top and bottom of the support 111. In addition, the support 111 may be further provided with a plurality of USB sockets 130 for supplying power to various electrical and electronic devices, and this degree of design change also falls within the scope of the present invention.

The plug socket 120 has a general structure in which a plug terminal insertion hole is formed and a ground terminal is provided, and the USB socket 130 may have a general structure into which a USB terminal can be inserted.

Of course, it goes without saying that the plug socket 120 and the USB socket 130 can be provided in various combinations at various positions on the head 110 and the support 111 as needed. In addition, the USB socket 130 is used to supply direct current power to electrical and electronic devices, and USB can generally be divided into USB Type-A, USB Type-B, and USB Type-C depending on its form. Accordingly, the head 110 or the support 111 can be equipped with a plurality of different types of USB sockets 130 in various combinations as needed.

The support 111 on which the plug socket 120 is provided may have various pillar shapes such as a triangular pillar, a pentagonal pillar, and a hexagonal pillar in addition to the square pillar shape. For example, in addition to one side of the support 111, the support 111 may also have a plug socket ( 120) may be further provided at equal intervals up and down.

Meanwhile, the power distribution unit 150 distributes AC 220V household power, which is the main power source, supplied through a power supply plug 101 connected to an outlet on an indoor wall, to the plug socket 120, USB socket 130, etc. At this time, the main power supplied through the power supply plug 101 is AC 220V, the same as the commercial power supplied to the plug socket 120.

This power distribution unit 150 can be built inside the head 110 or the support 111, and distributes the main power in the form of AC 220V household power to a plurality of plug sockets 120, and transforms and rectifies the main power. So, for example, it is converted into DC 5V USB power and distributed to a plurality of USB sockets 130.

Such a power distribution unit 150 can be configured to include a typical small SMPS (Switched Mode Power Supply), and through this SMPS, main power can be converted into alternating current and direct current power of various sizes.

Meanwhile, the input terminal of the power distribution unit 150 is provided with a control switch 160 that can turn on and off the main power input to the power distribution unit 150, and the control switch 160 controls the control unit 170.

At this time, the control switch 160 can be composed of a semiconductor switching element, a relay, and various other switches, and the main power supplied to the power distribution unit 150 can be controlled on and off through control of these switching elements or relays. there is.

This control unit 170 may be composed, for example, of a microcomputer (micom), which is an adapter unit (which has a transforming and rectifying function like a normal adapter) to convert the main power supplied through the power supply plug 101 into driving power. It is supplied and driven through 172, and this adapter unit 172 is built inside the head 110 or support 111.

Meanwhile, a power monitoring unit 180 is further provided at the input terminal of the power distribution unit 150 to monitor the actual power of the main power supplied to the power distribution unit 150 in real time. Although the power monitoring unit 180 is shown only at the front end of the control switch 160, it is not limited to this and can be installed at various locations where the main power can be monitored.

This power monitoring unit 180 may be configured, for example, as a current transformer. In this case, the detected current value is the actual total amount supplied in real time to the plug socket 120 and the USB socket 130 through the power distribution unit 150. It means the amount of current. Accordingly, the desk-mounted multi-tap 100 is supported on the wire hole 12 formed in the top 10 of the work or study desk 1 used in an office or residential building, and electrical and electronic devices are connected to a plurality of plug sockets 120. ) and the USB socket 130, the actual power of the electrical and electronic device can be calculated using the current detection value detected by the current transformer, which is the power monitoring unit 180. For example, if the current detection value is 2A, the actual power of 440W can be calculated by multiplying by 220V.

At this time, the power monitoring unit 180 may be composed of an instrument current transformer or various configurations that perform the same function. For example, in the case of an instrument current transformer, the current signal in analog form is transmitted to a microcomputer having an A/D converter function. The actual current value is input to the control unit 170 and converted into a digital signal to calculate the numerical actual current value, and the actual current value is multiplied by a voltage (for example, 220V) to calculate the actual power used.

Meanwhile, a display unit 190 is provided on the upper side of the head 110 to display the actual power used as a ratio or numerical value to the maximum allowable power. At this time, the display unit 190 is preferably composed of an LED module 192 in which a plurality of LEDs 192a are maintained at equal intervals and mounted on an LED substrate 192b.

This display unit 190 is controlled by the control unit 170 and can light up the plurality of LEDs 192a in proportion according to the ratio of the actual power used to the set maximum allowable power. That is, the control unit 170 divides the actual power used through the power monitoring unit 180 by the maximum allowable power to calculate the ratio (%) of the actual power used and turns on the plurality of LEDs 192a proportionally.

For example, as shown in (a) of FIG. 4, when the display unit 190 is made of an LED module 192 in which eight LEDs 192a are mounted on an LED board 192b, the maximum allowable limit of the desk-mounted multi-tap 100 is If the power is 2000W and the current actual power is 1500W, the ratio of the actual power to the maximum allowable power is 75%, so as shown in (b) of FIG. 4, 6 of the 8 LEDs 192a are used. By turning it on, users can easily check that there is more room for additional use of electrical and electronic devices. In this case, the control unit 170 calculates the ratio of actual power used and proportionally calculates the number of LEDs 192a to be turned on to control the lighting of the LEDs 192a. Each of the LEDs 192a may be made of a two-color LED capable of selectively outputting red and green. In this case, if the actual power used is less than the maximum allowable power, the plurality of LEDs 192a are turned green according to the ratio. It turns on, and when the actual power used exceeds the maximum allowable power, the LED 192a blinks in red as shown in (c) of FIG. 4 to warn the user.

Of course, the display unit 190 can be made of an LCD in addition to the LED module, and displays the usage in the form of a bar according to the ratio of actual power used to the maximum allowable power, or displays the ratio of actual power used to the maximum allowable power as a %. You may.

Meanwhile, the head 110 is equipped with a buzzer 182, and the control unit 170 sounds a warning sound through the buzzer 182 when the actual power detected through the power monitoring unit 180 exceeds the set maximum allowable power. Outputs . This is to warn the user that electrical and electronic devices are excessively connected.

In addition, the control unit 170 outputs a warning sound through the buzzer 182, and if the actual power used exceeds the set maximum allowable power for a set time (for example, 5 minutes), the control switch 160 is turned off to cut off the main power supplied to the power distribution unit 150 and at the same time additionally outputs a warning sound through the buzzer 182. At this time, the buzzer 182 can be replaced with a normal speaker to output various announcements, and all design changes to this extent fall within the scope of the present invention.

In addition, a tilt detection unit 184 is further provided inside the head 110 or the support 111, so that when the desk-mounted multi-tap 100 is tilted more than a set angle while standing vertically, a tilt signal is generated and the control unit 170 ) is entered. This tilt detection unit 184 may be composed of various types of tilt switches as well as tilt sensors, and all design changes to this extent fall within the scope of the present invention.

The tilt signal detected by the tilt detection unit 184 is input to the control unit 170. According to this configuration, the control unit 170 outputs a warning sound through the buzzer 182 when a tilt signal is input from the tilt detection unit 184. This is to warn the user to properly use the desk-mounted multi-tap 100 by supporting it vertically on a desk, etc. In this case, the control unit 170 outputs a warning sound through the buzzer 182 when it detects that the actual power used through the power monitoring unit 180 exceeds the minimum standard value (for example, 1 mA). This is to determine that it is safe because power is not supplied to electrical and electronic devices through the desk-mounted multi-tap (100) when the actual power used is below the minimum standard. Accordingly, the control unit 170 does not output a warning sound through the buzzer 182 when the actual power detected through the power monitoring unit 180 is below the minimum standard value.

In addition, the control unit 170 outputs a warning sound through the buzzer 182 and turns on the control switch 160 when a tilt detection signal is input from the tilt detection unit 184 even during the set time (for example, 1 minute). By turning it off, the main power supplied to the power distribution unit 150 is cut off and at the same time, an additional warning sound is output through the buzzer 182.

This not only prevents fires in various electrical devices and smartphones that the user is using while going out, but is also effective in saving energy by blocking power use in an inclined state.

Hereinafter, an example of using a desk-mounted multi-tap according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5.

In order to use the desk-mounted multi-tap 100 of the present invention, the power supply plug 101 is connected to an indoor wall outlet or a multi-conductor center placed on the floor.

Thereafter, for example, the plugs of general home appliances such as laptop PCs, tabletop humidifiers, and audio devices that are used on the top plate 10 of the desk 1 but require a supply of household power (e.g., commercial power of AC 220V) are plugged into the plug socket. Connect to (120), and connect the USB terminal of portable home appliances such as smartphones, tablet PCs, or their batteries that require USB power supply to the USB socket (130).

In this state, when the main power switch 140 is operated to input main power into the power distribution unit 150, the power distribution unit 150 distributes commercial power and USB power to the plug socket 120 and USB socket 130. to provide.

Meanwhile, when the main power is turned on by manipulating the main power switch 140, the main power is also supplied to the adapter unit 172. The adapter unit 172 converts the main power into driving power and provides it to the control unit 170 to drive the control unit 170. The current detection value and slope signal are detected from the power monitoring unit 180 and the slope detection unit 184, and these current detection values and slope signals are input to the control unit 170.

Accordingly, the control unit 170 compares the actual use power monitored through the power monitoring unit 180 with the set maximum allowable power and turns on the plurality of LEDs 192a of the display unit 190 in proportion, and the actual use power is the maximum allowable power. If the power is exceeded, all LEDs 192a blink and a warning sound is output through the buzzer 182 to warn the user.

In addition, when a tilt detection signal is input through the tilt detection unit 184, the control unit 170 outputs a warning sound through the buzzer 182 so that the user can normally use the desk-mounted multi-tap 100 vertically, and then for a set time. If a tilt detection signal is input from the tilt detection unit 184 for (for example, 1 minute), the control switch 160 is turned off to cut off the main power supplied to the power distribution unit 150 and at the same time turn on the buzzer 182. An additional warning sound is output.

Of course, when the tilt detection signal is input through the tilt detection unit 184, the control unit 170 compares the actual use power detected through the power monitoring unit 180 with the minimum standard value (for example, 1 mA) to determine the actual use power. If it is above the minimum standard, a warning sound is output through the buzzer 182, and if it is below the minimum standard, the warning sound is not output through the buzzer 182.
