Description

  The present invention relates to a distribution board configured by connecting a main breaker and a branch breaker with conductive bars such as a main bar and a branch bar, respectively.

  The distribution board 31 is configured by arranging electrical devices such as a main breaker (not shown) and a branch breaker 32 in a cabinet 33 and connecting the main breaker and the branch breaker 32 with a conductive bar. The conductive bar mainly includes a main bar 34 connected to the main breaker and a branch bar 35 connected to the branch breaker 32. The main bar 34 is provided with a terminal hole for connection to the main breaker at the end, and the branch bar 35 is provided with a connection hole 36 at a connection portion with the main bar 34. When the distribution board 1 is manufactured or when the branch breaker 32 is replaced after the distribution board 1 is installed, a tap hole 37 is provided in the main bar 34 at a position facing the connection hole 36 of the branch bar 35 each time. I was processing. The connection hole 36 of the branch bar 35 and the tap hole 37 of the main bar 34 are made to face each other, and the connection screw 38 is inserted and fastened to each.

In addition, as shown in Patent Document 1, when connecting a branch breaker to a branch bar, a method of using a substrate is also considered in order to fill an error in a hole position.

  However, in the above-mentioned conventional distribution board, tapping of the branch bar has to be performed each time, and the work for producing the distribution board and the work for replacing the branch breaker have become very complicated. . In addition, the branch breaker has various dimensions depending on the model, and it is necessary to perform tapping of the main bar at the mounting position in consideration of the dimension of the branch breaker, and the work is further complicated.

  Further, in the method using the substrate, it is necessary to manufacture parts separately, the manufacturing cost is increased, the parts are small, and management is troublesome.

  Therefore, the present invention has an object to provide a distribution board that can easily perform a production work of a distribution board and a replacement work of a breaker, and its structure is assumed to be connected to a branch bar in the main bar. A long hole is provided at the position, and the branch bar is formed with a tap hole at a position facing the long hole provided in the main trunk bar, or the branch bar is assumed to be connected to the main bar. In the main bar, tap holes are formed at positions facing the long holes provided in the branch bar, and the main bar and branch bar are each inserted with a connection screw in the long hole and tap hole. It is characterized by being connected to each other.

  In the distribution board according to the present invention, the main bar is provided with a long hole at a position assumed to be connected to the branch bar, and the branch bar is provided at a position facing the long hole provided in the main bar. A tapped hole is formed, or the branch bar is provided with a long hole at a position assumed to be connected to the main bar, and the main bar is tapped at a position facing the long hole provided in the branch bar. Holes are formed, and the main bar and branch bar are configured by inserting connection screws through the long holes and tap holes, respectively, so that they can be easily assembled even when branch breakers with different dimensions are arranged. With this structure, the distribution board can be easily manufactured and the branch breaker can be replaced, and the workability can be greatly improved.

  A distribution board according to the present invention will be described with reference to the accompanying drawings of FIGS.

  In the distribution board 1, electric devices such as a main breaker (not shown) and a branch breaker 3 are arranged in a cabinet 2, and these electric devices are connected by a conductive bar 4. The conductive bar 4 includes a main bar 5 connected to the main breaker and a branch bar 6 connected to the branch breaker 3.

  The main bar 5 is sized in consideration of the distance between the terminals of each phase to which the main bar 5 is connected in accordance with the main circuit breaker to be connected. The main bar 5 is provided with a terminal hole that is fixed to a terminal portion of the main breaker 5 by a terminal screw at the end. In addition, a long hole 7 is provided in a substantially central portion of the main bar 5.

  The branch bar 6 is sized in consideration of the distance between terminals to which the branch bar 6 is connected in accordance with the branch breaker 3 to be connected. The branch bar 6 is provided with a terminal hole 9 fixed to the terminal portion 3a of the branch breaker 3 by a terminal screw 8 at one end, and a tap hole 10 connected to the main bar 5 at the other end.

  A main breaker is arranged, and the main bar 5 is connected to the terminal portion of the main breaker. A branch bar 6 is connected to the terminal portion 3a of the branch breaker 3, and it is applied from the lower side of the main bar 5, and the long hole 7 of the main bar 5 is opposed to the tap hole 10 of the branch bar 6, Each of the connection screws 11 is inserted and fastened.

  Although not shown, a long hole may be provided at a position of the branch bar that is assumed to be connected to the main bar, and a tap hole may be provided in the main bar at a position opposite to the long hole. Similar to the distribution board shown in FIGS. 1 to 3, a branch bar is applied to the tap hole of the main bar, and a connection screw is inserted into the tap hole and the long hole, respectively, and is fastened and fixed. At this time, the arrangement position of the branch breaker can be adjusted within the range of the long holes provided in the branch bar.

  The arrangement position of the conductive bars is not limited to the main bar 5 having the same height as shown in FIG. 2, but the main bar 12 is arranged at different heights as shown in FIG. Alternatively, the one corresponding to the installation position of the main bar 12 may be used. Modifications can be made as appropriate without departing from the spirit of the present invention.

  In the state where the main breaker is arranged and the main bar 5 is connected to the terminal portion of the main breaker, if the branch breaker 3 to which the branch bar 6 is connected is arranged, the size of the branch breaker 3 varies depending on the model. The branch bars 6 are not arranged on the main bar 5 with a certain rule so that they are equally spaced. In the present invention, since the connection hole between the main bar 5 and the branch bar 6 is the long hole 7, the branch bar 6 can be fixed at an arbitrary position within the range of the long hole 7. When the distribution board 1 is manufactured or when the branch breaker 3 is replaced after the distribution board 1 is installed, a great effect can be obtained.
