Description

[0001]
BACKGROUND OF THE INVENTION
The present invention comprises a main switch, a plurality of branch switches, a terminal block electrically connected to the primary side of the main switch, and a circuit breaker electrically connected to the terminal block. The present invention relates to a residential distribution board.
[0002]
[Prior art]
In the distribution board for residential use, if the distribution board is used when a lighting contract is made for each time zone, supply power to the load equipment that operates in the time zone corresponding to the lighting contract for each time zone. For this purpose, a switch unit for lighting contracts for different time zones that obtains power from the primary side of the main switch is provided inside the distribution board.
[0003]
Switch units for lighting contracts by time of day are: a terminal block that is electrically connected to the primary side of the main switch using electric wires, and a wiring block that is electrically connected to the terminal blocks using electric wires. It is comprised including the vessel.
[0004]
When a switch unit for lighting contracts by time zone is installed in the distribution board, it is opposite to the main switch of multiple branch switches as seen from the multiple branch switches in the distribution board case. A switch unit for lighting contracts according to time of day was arranged in the equipment installation space (hereinafter referred to as free space) provided on the side.
[0005]
FIG. 4 shows an example in which a switch unit for an electric lamp contract according to time zone is disposed in a case of a conventional distribution board. The connection between the main switch 3 and the switch unit 5 for the lighting contract by time zone is made by connecting the primary terminal of the main switch and the terminal block 51 in the switch unit 5 for the electric contract by time slot to the electric wire 16. However, it is necessary to change the length L according to the number of branch switches and to create the wires 16 by connecting them.
[0006]
The load equipment connected to the switch unit 5 for lighting contracts by time zone has various rated capacities. Depending on the amount of power used by the load equipment, the wire thickness and wiring for each time zone It was necessary to change the rated current of the circuit breaker. When processing the electric wire, as shown in FIG. 5, the covering on both ends of the electric wire 17 is peeled off to an appropriate length, and the insulating cap 18 and the crimp terminal 19 are attached each time according to the thickness and rating of the electric wire. Had to be bent into a U-shape and manufactured.
[0007]
Further, the electric wire 16 needs to have a thickness corresponding to the rated current of the circuit breaker 52 or the main switch 3 and normally has a thickness capable of energizing 30 A or more. In that case, the electric wire 16 needs to be long enough to straddle the plurality of branch switches 4 and has a large thickness, so that the cost of the electric wire material is high.
[0008]
[Problems to be solved by the invention]
[0009]
In the present invention, the above-mentioned various problems are improved, the type of conductors to be electrically connected does not depend on the number of branch switches, the assembly is easy, and the cost of housing for a lighting contract by time zone is low. The issue is to provide an electrical panel.
[0010]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention is built in a case of a distribution board, arranged on a main switch and one side of the main switch, and electrically connected to the secondary side of the main switch. A plurality of connected branch switches, and each pole of a primary terminal of the main switch disposed in a device mounting space on the other side of the main switch opposite to the other branch side where the plurality of branch switches are disposed A terminal block having the same number of poles as the main switch electrically connected by a copper bar, and wiring that is disposed in the device mounting space on the same side as the terminal block and is electrically connected to the terminal block The residential distribution board is configured such that the incoming circuit from the transformer is connected to the terminal block .

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0012]
FIG. 1 shows a configuration diagram of a distribution board according to the present invention. 1 is a distribution board, 2 is a distribution board case, 3 is a main switch, 4 is a multi-branch switch, 5 is a switch unit for lighting contracts according to time of day, 51 is a terminal block, 52 is a wiring breaker , 6 is a device mounting space provided on the opposite side of the branch switch from the main switch, 7, 8, 9, 10, 11 are copper bars, 12, 13, 14 are incoming wires from the transformer. .
[0013]
In the case 2 of the distribution board 1, a main switch 3, a plurality of branch switches 4 connected to the secondary side of the main switch 3, a switch unit 5 for lighting contracts according to time zones, A device mounting space 6 is provided for mounting a switch unit for a lighting contract by time zone. The device mounting space 6 is provided on the side surface where the plurality of branch switches 4 are not located when viewed from the main switch 3.
[0014]
The switch unit 5 for hourly electric power contracts provided in the device mounting space 6 includes a terminal block 51 and a circuit breaker 52 for wiring.
[0015]
The terminal block 51 and the power supply side terminal of the circuit breaker 52 are connected by copper bars 10 and 11 having connecting portions at both ends as shown in FIG.
[0016]
The terminal block 51 and the primary terminal of the main switch 3 are connected by copper bars 7, 8, and 9 as shown in FIG. Three terminals are provided at one end of the terminal block 51 so as to be uniquely connected to the primary side terminal of the main switch 3. The copper bar 7, the incoming wire 12 from the transformer, and the copper bar 8 are provided. And the incoming wire 13 from the transformer, the copper bar 9 and the incoming wire 14 from the transformer can be fastened together.
[0017]
Also, three terminals are provided at the other end of the terminal block 51 so that the power supply side terminal of the wiring breaker 52 can be connected by the copper bars 10 and 11. FIG. 1 shows a connection example in which a load device having a rated voltage of 200 V is connected, and connection is made to the circuit breaker 52 using both ends of the terminals of the terminal block 51.
[0018]
The copper bars 7, 8, and 9 shown in FIG. 2 can be connected with an appropriate clearance so that the insulation distance can be maintained when the terminal block 51 and the primary terminal of the main switch 3 are connected.
[0019]
The copper bars 7, 8, 9, 10, and 11 are designed assuming the maximum energized capacity, and the switch unit 5 for the lighting contract according to the time zone installed in the equipment installation space 6. The positional relationship with the main switch 3 is always constant without depending on the number of branch switches 4 of the distribution board 1. Therefore, as the number of branch switches 4 increases or decreases, the positions and lengths of the copper bars 7, 8, 9 connecting the main switch 3 and the terminal block 51 of the switch unit 5 for the hourly lighting contract. Since it doesn't change, you need only one type.
[0020]
Further, as in the case of connecting the terminal block 51 and the main switch 3 by using an electric wire, an appropriate amount of the electric wire coating is removed, an insulating cap is passed, and a crimping terminal is further attached by crimping. Can be omitted.
[0021]
Moreover, the switch unit 5 for the lighting contract according to the time zone is completely independent from the mounting part for disposing the main switch 3 and the branch switch 4 in the case 2 of the distribution board 1. For this reason, if the distribution board has a device mounting space 6, it can be easily retrofitted even when the distribution board is completed.
[0022]
