Although not shown, the DC bus bar 80 is similarly fixed to the insulating support 110 in the vertical direction.
The bus 120 is, for example, a bus drawn from the ground or supplied from a power supply device (not shown).

  Next, attachment of the distribution board unit will be described with reference to the drawings. FIG. 6 shows a case where the DC distribution board unit 40 is attached. The DC distribution board unit 40 is placed on the induction support unit 100 and pushed into the back. Then, the male connector 61 on the back surface of the DC distribution board unit 40 and the female connector 62 in the insulating partition 90 are connected.

  At the time of connection, as shown in FIG. 4, the connection guide 612 of the male connector 61 is inserted into the guide hole 623 formed in the collar portion 622 of the female connector 62 and guided. In such a situation, it is continuously pushed in, and as shown in FIG. 5A, the connection pin 613 is fixed and electrically connected to the pin receiver 627. As a result, the bus 120, the DC bus bar 80, the female connector 62, and the male connector 61 are coupled and electrically connected to the internal circuit via the electric wire portion 614.

  Such connection is the same even when the AC distribution board unit 30 is added. The AC distribution board unit 30 is placed on the induction support unit 100 and pushed into the back. Then, the male connector 51 on the back surface of the AC distribution board unit 30 and the female connector 52 in the insulating partition 90 are connected. As a result, the bus 120, the AC bus bar 70, the female connector 52, and the male connector 51 are coupled and electrically connected to the internal circuit via the electric wire portion 514.

  As described above, in the unit type distribution board of this embodiment, the AC distribution board unit 30 is electrically connected to the AC bus bar 70 simply by inserting the AC distribution board unit 30 into the rack body 10. Since it is electrically connected to the DC bus bar 80 simply by being inserted into the rack body 10, the expansion work is facilitated.

  Further, the connection positions are mechanically determined in advance so that the AC distribution board unit 30 is connected to the AC connection section 50 and the DC distribution board unit 40 is connected to the DC connection section 60. Therefore, it is not necessary to consider where to be installed by humans, and simply connecting the AC distribution board unit 30 or the DC distribution board unit 40 is connected. However, expansion work has become easier.

  Further, an AC female connector 52 and a DC female connector 62 are arranged side by side in one additional space 11, and the female connector 51 is connected to the back of the AC distribution board unit 30. Since the female connector 61 is arranged at a different position on the rear surface of the distribution board unit 40, it can be properly installed regardless of whether the distribution board unit 30 for AC or the distribution board unit 40 for DC is added. It is easy to use.

The unit type distribution board of this embodiment has been described above. This embodiment has been described as having a two-wire AC / DC bus bar. However, a structure using a three-wire AC bus bar may be used.
Moreover, it is good also as a unit type distribution board which has a bus bar only for a two-wire type alternating current, only a three-wire type alternating current, or a two-wire type direct current. These structures are appropriately selected.
