  An inner unit mounting plate with an inner unit consisting of a main breaker, a conductive bar connected to the main breaker, and a plurality of branch breakers connected to the conductive bar, etc. is stored in the main body with the front open and inside the back plate In the distribution board, which is fixed and closed with a cover and the main body is fixed to the wall surface, slide mechanisms are provided at the four corners of the inner unit mounting plate so that it can be pulled out to the front side of the main unit. Is fixed so that it can be engaged and disengaged at a position where it is stored in the main body and a position where it is pulled out from the main body. Further, when the inner unit mounting plate is pulled out to the front side of the main body, the wire insertion hole of the load-side terminal of the branch breaker is formed so as to be positioned in front of the front end of the side plate of the main body.

  First Embodiment A distribution board according to a first embodiment of the present invention will be described with reference to the accompanying drawings of FIGS.

  The distribution board 1 comprises a main body 2 in which a side plate 2b is erected on the entire circumference of a rectangular back plate 2a to form a front surface and a cover 3 that closes the front surface opening of the main body 2. The main breaker 4, a conductive bar (not shown) connected to the main breaker 4, a plurality of branch breakers 5 connected to the conductive bar 4, and the front breaker so as not to touch the conductive bar and the branch breaker An internal unit comprising a load name display plate 6 for displaying the connection load 5 is attached to the internal unit mounting plate 7, and the internal unit mounting plate 7 is provided with slide mechanisms 8 at four corners and inside the back plate 2 a of the main body 2. It is fixed to and is retractable.

  The slide mechanism 8 includes a support member 9 having a U-shaped guide portion 9 a formed in the front-rear direction, a rail 10 having a U-shaped cross section that slides along the guide portion 9 a of the support member 9, and the opposite of the rail 10. A regulation pin 11 that is inserted into a long hole 10a formed in the longitudinal direction of the two pieces to regulate the slide width of the rail 10, and a support member 9 is rotatably supported so as to support the lower surface of the rail 10. The first roller 12 and the second roller 13 rotatably supported by the support member 9 so as to contact the inner side surface of the rail 10, the inner machine mounting plate 7 is fixed to the tip of the rail 10, A support member 9 is fixed to the back plate 2 a of the main body 2 so that the inner unit mounting plate 7 can slide in the front-rear direction with respect to the main body 2. The first roller 12 is provided only in the slide mechanism 8 on the lower left and right sides, and a low friction member 14 made of a resin material is formed at a portion where the rail 10 and the support member 9 are in sliding contact with each other to reduce frictional resistance. Is attached.

In these slide mechanisms 8, upper and lower two support members 9 are connected to each other, and a locked portion 16 to which a handle lever 15 provided on two opposite sides of the inner unit mounting plate 7 is engaged and disengaged is provided at an intermediate portion. Is formed. The handle lever 15 is a handle portion 17 to be put on when sliding the inner unit mounting plate 7, and a lever portion that is pivotally supported by the handle portion 17 with a shaft portion 18a as a fulcrum so as to be engaged and disengaged. 18b, a locking portion 18c that is formed on the opposite side of the lever portion 18b with respect to the shaft portion 18a and interlocks with the operation of the lever portion 18b, and a biasing spring 19 that biases the locking portion 18c in the locking direction. It is formed. Then, the handle lever 15 is put on the handle portion 17 and pushes the lever portion 18b inward with the fingertip, thereby turning the shaft portion 18a as a fulcrum to open the locking portion 18c outward, and the fingertip from the lever portion 18b. When released, the locking portion 18c is closed inward by the force of the biasing spring 19. The locked portion 16 includes a first locking surface 16a on which the inner surface of the locking portion 18c is locked at a position where the inner unit mounting plate 7 is housed on the back plate 2a side of the main body 2, and an inner unit mounting plate. A second locking surface 16 b is formed on the outer surface of the locking portion 18 c at a position where 7 is pulled out from the main body 2.

  In the distribution board 1 formed in this way, the inner side surface of the locking portion 18c of the handle lever 15 is the locked portion 16 at the position where the inner unit mounting plate 7 is pushed into the back plate 2a side of the main body 2 and stored. When the wiring is performed on the load side terminal 5a of the branch breaker 5, the inner unit mounting plate 7 is pulled out from the main body 2 to perform the work. In order to pull out the internal unit mounting plate 7, first, the cover 3 is removed from the main body 2, and then the handle levers 15 on both the left and right sides are held, and the lever portion 18b is pushed with a fingertip to release the locking portion 18c. When the inner unit mounting plate 7 is pulled out as it is and the finger is released from the lever portion 18b at the position where it is stopped, the locking portion 18c is rotated inward by the force of the urging spring 19, and the outer surface of the locking portion 18c. Is fixed by being locked to the second locking surface 16 b of the locked portion 16. At this time, the inner unit mounting plate 7 is drawn out to a position where the wire insertion hole 5b of the load side terminal 5a of the branch breaker 5 is in front of the front end of the side plate 2b of the main body 2. Thereby, it is possible to work without limitation of gutter space at the time of wiring work to the load side terminal 5a. Note that the wiring to the load side terminal 5a is drawn into the main body 2 from the wiring hole 2c formed in the back plate 2a of the main body 2. When the wiring is completed, the handle lever 15 is held again, and the lever portion 18b is pushed with the fingertip to release the locking portion 18c and pushed into the back plate 2a side of the main body 2. Then, the finger is separated from the lever portion 18b at the position where the inner unit mounting plate 7 abuts, and the locking portion 18c is locked to the locked portion 16. After the wiring is completed, the inner unit mounting plate 7 is screwed to the support member 9 with the fixing screw 20, and finally the front opening of the main body 2 is covered with the cover 3.

  In this embodiment, the inner unit mounting plate is formed so as to be pulled out horizontally forward, but as shown in FIG. 5, the inner unit mounting plate 7 may be formed so as to be pulled out obliquely downward. Accordingly, when the distribution board 1 is disposed near the ceiling, the distance between the upper row branch breakers 5 and the ceiling can be increased, so that the wiring to the upper row branch breakers 5 is facilitated, and FIG. As shown in FIG. 2, the inner unit mounting plate 7 may be formed so as to be pivotable in the vertical direction with the pivot shaft 21 as a fulcrum, so that the work can be done by looking at the wire insertion hole of the load side terminal 5a of the branch breaker 5. As a result, wiring becomes easier.

  Further, the drawer structure of the internal unit mounting plate is not limited to the slide mechanism. For example, as shown in FIG. 7, one end of the substantially I-shaped arm 40 is pivotally attached to the four corners of the internal unit mounting plate 7. At the same time, the multiple ends can be attached to the back plate 2a of the main body 2 so that they can be pulled out. Similarly, the arm 60 can be pulled out by a substantially triangular arm 50 as shown in FIG. 8, or bendable as shown in FIG. It may be possible to pull it out.

  In the present embodiment, the first roller 12 is provided only on the lower slide mechanism 8, but may be provided only on the upper slide mechanism 8 or may be provided on all the slide mechanisms 8. However, the second roller may be provided only in either the upper or lower slide mechanism. Further, other shapes and structures can be appropriately changed and implemented without departing from the spirit of the present invention.
