By doing so, the upper lid 14 can be shared with any of the bases 13. Reference numeral 51 is a notch that avoids the peripheral edge 52.

The inner unit 3 is attached inside the housing 1. In the embodiment, the internal unit 3 is composed of a main switch 30 and a plurality of branch switches 31, which are attached to a mounting plate 32 by screws 29, and the mounting plate 32 holds the body 40 with the screws 40 and the body 9 fitted therein. It is attached by the part 41. 3
3 is an input-side terminal portion of the master switch 30, 34 is an output-side terminal portion thereof, 35 is an L-shaped feed bar, 36
Is a terminal section 49 on the input side of the branch switch 31 which is composed of three neutral bars and a pair of voltage bars and which are arranged in two rows.
Connect to. Note that 100 V can be input by connecting the neutral bar and the voltage bar, and 200 V can be input by connecting the pair of voltage bars. 36 '(FIG. 6) is a connecting piece for connecting the bar 36 and the terminal portion 49, 37
Is a terminal on the output side of the branch switch 31, and 38 is a terminal 37 on the output side of the lower row of the branch switch 31 and the opening 6 for wiring.
It is a wiring space for connecting with the branch switch 31 and the side wall 2
It is formed by a gap with 1.

As shown in FIG. 3, the wiring 26 is wired in the housing 1 through the wiring duct 2 and the wiring opening 6, and the input line of the master switch 30 is connected to the input terminal 33 to branch and open and close. The load output line of the switch 31 is connected to the output terminal portion 49 of the branch switch 31. Reference numeral 39 denotes a wiring bottom side opening provided at the bottom of the body 9 and closed by a knockout plate. As shown in FIG.
It is used when the wiring 46 is pierced through. Reference numeral 47 denotes a wiring opening formed in the base 13 of the wiring duct 2 and closed by a notch plate, which opens when the wiring 46 is constructed.

According to this embodiment, the wiring duct 2 is attached to the mounting surface 4, the hook receiving portion 7 of the housing 1 is moved so as to approach the mounting surface 4, and the housing of the wiring duct 2 is moved. It is hooked on the body hooking portion 8 and temporarily fixed, and then the housing 1 is attached to the mounting surface 4 for construction. Further, the inner unit 3 is mounted in the housing 1. Note that the inner surface 3 may be attached to the housing 1 and then the housing 1 may be temporarily fixed to the wiring duct 2 and the mounting surface 4 may be attached.

By hooking the hook receiving portion 7 and the housing hooking portion 8 in this manner, the wiring duct 2 and the wiring opening 6 can be made to communicate with each other, so that the housing 1 and the wiring duct 2 are connected. Can be easily attached to the mounting surface 4, and the mounting workability can be improved. Further, since the hook receiving portions 7 are provided on both sides of the wiring opening 6, the wiring 26 does not get in the way of the wiring opening 6, the wiring 26 can be concealed reliably, and the connection of the wiring duct 2 is stable. You can improve your sex.

Further, the housing 1 has a body 9 having the mounting portion 5, locking pieces 8 and 8 ', and a side wall 21 on the periphery thereof, and an engaging portion 10 for locking the locking piece 8. The cover 11 covers the front opening of the body 9 and the hook receiving portion 7 is provided in the vicinity of the locking piece 8. Therefore, by bringing the hook receiving portion 7 and the locking piece 8 close to each other, It is possible to simplify the structure of the molding die.

The housing hooking portion 12 has a dovetail-like shape, the hooking receiving portion 7 is a dovetail groove recessed in the outer surface of the side wall 21, and the locking piece 8 is formed on the front end side of the dovetail groove bottom. Since it is a hook shape, it is easy to take a shape in which the locking piece 8 is also molded at the molding part of the mold for forming the dovetail groove, so that the molding mold can be further simplified. In the present invention, the housing 1 is fixed to the mounting surface 4 and the hook receiving portion 7 thereof is provided.
Alternatively, the housing hooking portion 12 of the wiring duct 2 may be hooked, or the wiring duct 2 may be hooked and then attached to the mounting surface.

According to the distribution board of the first aspect, the wiring duct is attached to the mounting surface, and the hook receiving portion of the housing is hooked on the housing hanging portion of the wiring duct to temporarily fix the housing. Either attach it to the mounting surface, or fix the case to which the internal unit is attached to the mounting surface, and hook the hooking part of the case of the wiring duct to the hooking part. As described above, by hooking the hook receiving portion and the housing hook portion, the wiring duct and the wiring opening can be made to communicate with each other, so that the housing and the wiring duct can be easily attached to the mounting surface. Therefore, there is an effect that the mounting workability can be improved.

According to the distribution board of claim 2, in claim 1, since the hook receiving portions are provided on both sides of the wiring opening, the wiring does not interfere with the wiring opening and the wiring is not disturbed. The concealment can be ensured, and the stability of the connection of the wiring duct can be improved. According to the distribution board of claim 3, claim 2
In, the casing has a body having the mounting portion, a locking piece, and a side wall on the periphery, and an engaging portion for locking the locking piece to cover the front opening of the body. Since the hook receiving portion is provided in the vicinity of the locking piece, it is possible to simplify the structure of the molding die of the housing by bringing the hook receiving portion and the locking piece close to each other. .

According to a fourth aspect of the distribution board, in the third aspect, the housing hooking portion has a dovetail shape, and the hooking receiving portion has a dovetail groove shape recessed on the outer surface of the side wall.
Since the locking piece is a hook shape formed on the front end side of the dovetail-shaped bottom portion, it is easy to take a shape in which the locking piece is also molded at the molding portion of the mold forming the dovetail groove, so that the molding die is much more The mold can be simplified.
