Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a power line bar for a residential distribution board that connects a main breaker and a plurality of branch breakers.

[Background Art] Some residential power distribution boards connect a plurality of branch breakers to one main breaker using two power line bars, one on the charging side and the other on the grounding side. However, in conventional power line bars,
The shape of the one used on the charging side and the one used on the grounding side are different, so there are always two
In addition to having to prepare various types of power line bars, the wiring work can be time-consuming.

[Purpose of the invention] The present invention was devised in view of these points, and its purpose is to make the one used on the charging side and the one used on the grounding side the same shape. It is possible to provide a power line bar on the distribution board.

[Disclosure of the invention] The present invention provides a power line bar for connecting the charging side and the grounding side, which consists of a main piece and a plurality of branch pieces extending from both side edges of the main piece. The branch piece extending from one side edge and the branch piece extending from the other side edge of the main piece are both line-symmetrical with the axis of symmetry being a line perpendicular to the main piece at the longitudinal center of the main piece. At the same time, each branch piece is formed into an L-shape that extends in a direction perpendicular to one surface of the main piece and then bends to the side, and the charging side and the grounding side are turned inside out. It is characterized by the fact that the main pieces are arranged offset in the longitudinal direction, and by turning the same shape upside down, it can be used on both the charging side and the grounding side. It is something.

The present invention will be described below in detail based on the illustrated embodiment. FIG. 1 shows a distribution board, in which a main breaker 11 and a plurality of branch breakers 12, four in the illustrated example, are installed in a case 10. is installed. Of the four branch breakers 12, three are arranged in parallel, and the other one is connected to the main breaker 1.
1, and between the row of three branch breakers 12 and the row of the main breaker 11 and the branch breakers 12 adjacent thereto, two power line bars 1, 1 are installed so as to face each other. It is set up as follows.

The main breaker 11 and branch breaker 12 are
It is connected by the two power line bars 1,1. The two power line bars 1, 1 for the charging side connection and the grounding side connection both extend from the main piece 2 and both side edges of this main piece 2 in a direction perpendicular to the surface of the main piece 2, and then extend laterally. It consists of a plurality of L-shaped branch pieces 3 extending from each other, and the tip of each branch piece 3 is connected to each terminal part of the main breaker 11 or branch breaker 12, and the power line bar on the charging side 1
Even if the power line bar 1 is on the ground side, the branch piece 3 that extends from one side edge of the main piece 2 and is connected to the main breaker 11 and the branch breaker 12 is connected to the main piece 2 in the longitudinal direction. Branch pieces 3 extending from both ends and extending from the other side edge and connected to the three branch breakers 12 extend from both longitudinal ends and the longitudinal center of the main piece 2. It is becoming. In other words, not only the branch piece 3 extending from one side edge of the main piece 2 but also the branch piece 3 extending from the other side edge of the main piece 2 are perpendicular to the main piece 2 at the longitudinal center of the main piece 2. The power line bar 1 on the grounding side is simply turned over and shifted in the longitudinal direction with respect to the power line bar 1 on the charging side. They have exactly the same shape, but are placed in the same position.

In addition, each branch piece 3 is L-shaped, and
Since the pair of power line bars 1, 1 are in a reverse relationship with each other, when the pair of power line bars 1, 1 are placed facing each other and shifted in the longitudinal direction, the insulation distance between both power line bars 1, 1 is At the same time, as is clear from FIGS. 5 and 6, the distance L between the breakers 11 and 12 arranged on both sides of the power line bars 1 and 1 can be reduced.

[Effect of the device] As described above, in the present invention, the branch piece extending from one side edge of the main piece and the branch piece extending from the other side edge of the main piece both extend in the longitudinal direction of the main piece. Because they extend from positions that are line symmetrical with the axis of symmetry being the line perpendicular to the main piece at the center, the relationship between what is used on the charging side and what is used on the grounding side is simply reversed. Since it is possible to use products with the same shape, and only one type needs to be prepared, manufacturing is easy and connection work between breakers is also easy. Furthermore, each branch piece is formed in an L-shape that extends in a direction perpendicular to one surface of the main piece and then bends to the side. Since the breakers are arranged offset in the longitudinal direction, it is possible to increase the insulation distance between the power line bars on the charging side and the grounding side, and at the same time, the distance between the breakers connected to each other by the power line bars can be increased. can be made smaller.
