Description

  The present invention is a residential distribution board that is configured by attaching a rail and a device mounting panel to a base, and arranging a main breaker / branch breaker on the rail and the device mounting panel, and using the base bottom attached to a wall surface. It relates to the base structure.

  A residential distribution board comprises a base body, a cover body, and a cover body, and an electrical device such as a main breaker or a branch breaker is arranged on the housing. For example, as shown in the figure, the arrangement is such that the main breaker is arranged on the left side, and the branch breakers corresponding to the number of circuits are arranged in stages on the right side of the main breaker. The electrical devices are connected by conductor bars and electric wires. As for the base, a through hole for entering the residential distribution board from the wall surface is provided on the bottom surface, and side walls are erected on the four sides of the bottom surface. This side wall was formed so as to cover the side surface of the circuit breaker.

Moreover, there was a distribution board as described in Patent Document 1.
JP-A-8-237820

  In the distribution board for houses using the above-mentioned housing, when connecting conductor bars and electric wires to the main breaker / branch breaker, the side wall of the base is in the way, and the work is done in a narrow space. Therefore, there is a drawback that work efficiency is poor.

  Moreover, in the distribution board as described in patent document 1, although workability | operativity of an electric wire connection is improved, preparation of the apparatus takes time, and the distribution board for houses was also expensive.

  An object of the present invention is to provide a residential distribution board base structure that greatly improves the efficiency of connection work of electric wires to a breaker terminal with a simple structure. Has a through hole for entering the residential distribution board, and a side wall is erected on the periphery, and the side wall is lower than the position of the terminal portion provided on the side surface of the main breaker / branch breaker. It forms so that it may become.

  In the present invention, the base is provided with a through-hole for entering a residential distribution board on the bottom surface, and a side wall is erected on the periphery, and the side wall is provided on the side surface of the main breaker / branch breaker. Because the wiring space is secured at the same height as that of the main breaker / branch breaker terminals, the conductor bars and wires are connected to the terminals. Efficiency can be greatly improved.

  The base structure of the residential distribution board according to the present invention will be described with reference to the accompanying drawings of FIGS.

  The residential distribution board 1 is configured by arranging electrical devices such as a main breaker 3 and a branch breaker 4 in a housing 2. The housing 2 is attached to the base body 7 having the through hole 5 on the bottom surface and the opening 6 on the front surface, the cover body 8 surrounding the front surface opening 6 of the base 7, and the breakers 3 and 4. It is comprised with the cover body 11 which provided the window which exposes the operation handle 9, the display 10, etc., and also covers the front surface with the door body 12.

  A rail 13 and a device mounting panel 14 are attached to the base 7. Electrical devices such as the main breaker 3 and the branch breaker 4 are placed on the rail 13 and the device mounting panel 14. As an example of the arrangement of the electrical equipment, as shown in FIG. 1, the main breaker 3 is arranged on the left side, and the branch breakers 4 corresponding to the number of circuits are arranged in stages on the right side of the main breaker 3. The electrical devices are connected by a conductive bar 15 or an electric wire.

  The main breaker 3 and the branch breaker 4 form terminal portions for connecting the conductive bars 15 and the electric wires. A commercial power supply is connected to the power supply side terminal 3a of the main breaker 3, and the power supply side terminal 4a of the branch breaker 4 is energized from the load side terminal 3b of the main breaker 3 by the conductor bar 15. An electric wire connected to each load device is connected to the load side terminal 4 b of the branch breaker 4, and is output from the residential distribution board 1 through the through hole 5 of the base 7.

  The residential distribution board 1 according to the present invention is of a type called an exposure type that is attached with the bottom surface of the base 7 in close contact with the wall surface. The side walls 16 erected on the four sides of the base 7 protrude from the wall surface to the front surface. The side wall 16 of the base 7 increases the efficiency of connection work from the load side terminal 3b of the arranged main breaker 3 to the power source side terminal 4a of the branch breaker 4 and from the load side terminal 4b of the branch breaker 4 to the load device. In order to improve, the side wall 16 is formed to the height H at which the terminal portion is exposed in the state viewed from the side surface of the residential distribution board 1.

  When the side wall of the base is formed higher than the terminal part of the breaker as in the case of a conventional case, the hand hits the side wall during power distribution work to the breaker, and work in a small gap between the breaker and the side wall However, in the residential distribution board 1 of the present invention, since the side wall 16 is formed lower than the terminal portion of the breaker, it can be smoothly operated without interfering with the connection operation to the terminal portion. It is.

It is a perspective view which shows the base structure of the distribution board for houses concerning this invention. It is the front view (a) which shows the state which attached the cover body to the distribution board for houses, and also the front view (b) which shows the state which attached the door body. It is a principal part enlarged view in FIG. It is a side view in FIG.
