Referring to the power distribution flow of the configuration of the present invention described so far, DC power (eg, 24V) is first input from the input terminal 120 provided on the rear panel 114 of the case 110.

The input DC power is supplied with negative (-) power to one side of the output terminal 130 by the first connection line 121a, and positive power is supplied by the second connection line 121b to the distributor and the breaker ( 160). After the distribution is regulated by the third power line 121c to the DC power supply (eg, 12V) set in each of the distributors and the breakers 160, the fourth connection line 121d is transferred to the output terminal 130.

Here, the power input through the second connection line 121b is measured via the current sensor 140 in the total amount of current.

Current sensor 140 in the present invention uses a form capable of reading the current of 1 ± 0.5 ~ 30 ± 0.5 A.

Information about the total amount of current measured by the current sensor 140 is transmitted to the display device 170, and at the same time, up to 5V power required for driving the display device 170 is supplied. As a detailed configuration for enabling this, a cable connector 142 and a plurality of cables 144 are included.

The cable connector 142 is connected to one side of the current sensor 140 and is electrically connected to the plurality of cables 144.

As shown, the display device 170 is configured to include a display unit 171, a circuit unit 173 for driving the display unit 171, and an operation switch 175.

The display unit 171 receives electrical signals related to the total amount of current measured from the current sensor (reference numeral 140 of FIG. 2) and displays the visual information.

As the display unit 171 according to the present invention, various components for outputting visual information may be used, but the total current amount and voltage can be easily displayed in Arabic numerals, as well as a low-cost 7-segment. (segment) is available.

The 7-segment is installed through the front panel 112, but is preferably provided to be further exposed to the outside so that the user can easily check the desired information from the front.

 The display unit 171 may be controlled to drive the circuit unit 173 mounted on the inner wall of the front panel 112. However, since the circuit unit 173 is the same as the well-known 7-segment driving PCB circuit, a detailed description thereof will be omitted.

The operation switch 175 in the display device 170 of the present invention uses a tack switch.

The tack switch is a switch having a single button of a push method, and implements a function set according to a click order by a user.

In the present invention, three functions are implemented through the circuit unit 173 and the display unit 171. One of the functions is to display the total amount of current, the second is to display the voltage, and the third is to switch to the power saving mode (ie, sleeping mode).

These functions may be sequentially implemented according to the click order of the operation switch 175, that is, the tack switch.

And when each function is implemented in accordance with the click order of the operation switch 175, in order to easily recognize the user, it may be provided with a plurality of LED units to emit light corresponding to the function.

The plurality of LED units 181, 183, and 185 are provided at one side of the display unit 171. In particular, the first (181) of the three LED unit shown is the total current amount display state, the second (183) is the voltage display state, the third (185) the power on / off state To inform. However, this form may be changed and applied little by little according to various embodiments.

In addition, when the plurality of LED units 181, 183, and 185 are implemented in different colors, the user may more easily check the current state of the power distribution panel.

Particularly, when the power distribution panel according to the present invention is in the power saving mode, the remaining LED units 181 and 183 and the display unit 171 except for the LED unit 185 indicating the power on / off state are turned off and unnecessary. Suppresses power consumption

The figure shows the back panel of the van.

Referring to FIG. 5 and FIG. 6, it can be seen that the LTE is configured with a slightly different layout structure than the above-described power distribution panel for LTE. It is.

Therefore, only the differences regarding the arrangement shape will be briefly described.

Referring to FIG. 5, it can be seen that the display device 170 having the same shape as that of the first embodiment is provided on one side on the front panel 112. However, the structure of the divider and the breaker 160 is disposed up and down, because it is a structure suitable for a large number of power distribution compared to the first embodiment described above.

That is, in the first embodiment, four distribution ports and four breakers 160 for four power distributions are provided, whereas in the second embodiment, ten distribution ports and ten for ten power distributions are provided. The breaker 160 is provided. To this end, each breaker 160 is disposed up and down.

Referring to FIG. 6, it is possible to check the appearance of the input terminal 120 and the output terminal 130 provided on the rear panel 114. In this case, as described above, the power distributed to ten In order to output, the output terminal 130 is disposed in a suitable structure.

In particular, in this case, a step 133 may be provided between the terminals in order to prevent a short problem between the output terminal 130a disposed above and the output terminal 130b disposed below.

FIG. 8 is a block diagram illustrating an operation flow of a display device in a power distribution panel having a total current amount display function according to first and second embodiments of the present invention.

Referring to FIG. 8, first, a power supply of DC 24V is received (ST10). This is possible by electrically connecting the input terminal. It is regulated by a DC 12V supply, while some are regulated by a DC 5V supply. In this case, the DC 12V power is distributed and then output to be supplied to external power equipment, and the DC 5V power is required to drive the display device.

However, the total power of DC 12V is measured by the current sensor (ST120).

Then, the measured total amount of current is transmitted as an electrical signal to the CPU of the circuit unit, and then output to the outside through the display unit (ie, the INDICATOR of FIG. 8).

At the same time, the voltage measured during the power distribution process is also transmitted as an electrical signal to the CPU of the circuit unit, and then output to the outside through the display unit (ie, the INDICATOR of FIG. 8).

In addition, the entire driving of such a display device is controlled by the operation (ie, KEY INPUT in FIG. 8) command of the operation switch being applied to the CPU of the circuit unit (ST30).

This signal flow allows the display device to output the total amount of current and voltage during the power distribution process in the form of visual information, which the user can easily identify.

As described above, according to the present invention, while performing stable power supply by distributing DC power, information on the total amount of current (or voltage) can be visually checked through simple operation as necessary. The result is less effort for the operator overseeing the power distribution situation.

In addition, according to the present invention, the display function can be switched to a power saving state by a simple switch operation, thereby preventing unnecessary power consumption.

It has been described with respect to the preferred embodiment of the power distribution panel having the current amount display function according to the present invention.
