CONNECTING BRACKET OF DISTRIBUTION PANEL AND DISTRIBUTION PANEL HAVING THE SAME}

The present invention relates to a distribution bracket and a distribution panel provided with the same, and more particularly, to a distribution panel connection bracket and a distribution panel having the same, which can easily electrically connect the bus bar and the magnetic line disposed perpendicular to each other in the distribution panel.

In general, the distribution panel is a device for supplying and cutting off power drawn from the outside by electrically connecting the main circuit breaker, the auxiliary circuit breaker, and the circuit breaker to the inner panel having the enclosure.

These distribution boards are equipped with busbars to electrically connect the respective breakers.

That is, one side is composed of a bus bar (bus booth bar) connected to the output terminal of the main circuit breaker to induce power, and a own ship (charity bus bar) connected to the bus bar and supplying the divided power to each auxiliary circuit breaker.

Specifically, the bus bar and the magnetic line cross each other to be interconnected by fixing with fastening means such as bolts or screws.

However, in the conventional connection fastening method as described above, a gap is generated in the connection part by the assembly step of the buses and the own ships, and the bending position of the buses and the ships is bent downward to compensate for the gap. There was a problem that the unnecessary work process is accompanied because it is fixed by the fastening means.

In addition, in order to fasten with bolts, etc. at the connection location point of the mother ship and the own ship, each of the fastening holes must be drilled in advance. If each fastening hole is not located in a straight line, the fastening work cannot be performed. There was a problem of this deterioration.

In particular, when the arrangement of the circuit breakers are differently arranged or replaced, the inconvenience of having to dismantle and assemble all the fastening means coupled to the bus and the own ship occurs.

In order to solve this problem, various connecting members and brackets for connecting the mother ship and the own ship have been developed.

However, the connection brackets for the distribution panel of the related art have a complicated structure and are difficult to assemble, and not only have difficulty in working, but also require many processes to manufacture, and thus have difficulty in applying to actual products.

When the brackets are coupled, the space occupied by the side portion 112 and the fastening portion 130 increases in the horizontal direction in which the plurality of buses 310 are disposed, and thus the distance between the buses 310 must be increased. The transverse size of becomes large as a whole.

However, as shown in FIG. 5 (b), the first wing part 115 and the second wing part 125 are formed on the bottom part 111 and the cover part 120, and the first wing part ( In the structure of coupling the 115 and the second wing portion 125 to the fastening portion 130, when the bracket is coupled to the bus bar 310, the side portion 112 in the horizontal direction in which a plurality of bus bar 310 is disposed Since the space occupied by the fastening part 130 is reduced, the distance between the buses 310 can be reduced, so that the horizontal size of the distribution panel can be reduced as a whole.

In addition, the present invention is to mount the bracket only to the mother bus 310 without the need to bend or modify the magnetic line 320 electrically connected to the mother bus 310, and when the magnetic line 320 is coupled to the bracket and the mother bus 310 and Since the magnetic lines 320 are electrically connected to each other, the electrical connection between the bus line 310 and the magnetic lines 320 may be more easily performed at the distribution panel.

In addition, even if the thickness of the bus line 310 is changed, if the distance between the bottom portion 111 and the cover portion 120 is adjusted, the bus line 310 can be easily coupled to the bus bar coupling part 100. have.

The present invention is easy to manufacture because the bus bar coupling portion 100 and the charcoal coupling portion 200 constituting the connection panel for the panel board may be cut after pressing using a press or the like.

In addition, it is easy to connect and couple the bus 310 and the ship 320 to the bus coupler 100 and the char coupler 200, the workability is good, and the structure is simple, easy to assemble in the field It works.

As shown in FIG. 4, the switchboard of the present invention having the connection bracket as described above includes a case, a bus bar 310 disposed inside the case and connected to the main circuit breaker, and disposed in the case and connected to the auxiliary circuit breaker. It includes a connected magnetic line 320, and a connecting bracket for electrically connecting the bus line 310 and the magnetic line 320 by the bus bar coupling unit 100 and the char line coupling unit 200.

Compared to the first embodiment, the second embodiment has a difference in the fastening unit 130, and will be described with reference to this.

In the second embodiment, the fastening part 130 is integrally connected to the receiving part 110.

The fastening part 130 is formed of four, protruding in the horizontal direction extending from both sides of the bottom surface 111 and both sides of the end portion of the side portion 112.

That is, like the first wing portion 115 of the first embodiment, a total of four fastening portions 130 are formed.

The fastening part 130 includes a first bent part 136, a second bent part 137, and an elastic part 138.

The first bent portion 136 is bent in the same direction as the side portion 112 on both sides of the bottom portion 111.

The second bent portion 137 is bent in the direction in which the bus bar 310 is disposed in the first bent portion 136.

The elastic part 138 is bent at the second bent part 137 to elastically press the cover part 120 in contact with the other surface of the bus bar 310 toward the bus bar 310.

As the first bent portion 136 or the second bent portion 137 is bent by an external force, the fastening portion 130 closely couples the cover portion 120 to the other surface of the bus line 310.

Looking at the process of coupling the bus bar 310 to the bus bar coupling portion 100 using the bracket of the second embodiment in more detail, as shown in Figure 7 (a) the fastening portion 130 is the receiving portion ( In the horizontal direction.

That is, the first bent portion 136 is formed in the same direction as the bottom surface portion 111, and the second bent portion 137 and the elastic portion 138 are bent, respectively.

Thereafter, as shown in FIG. 7B, the bus bar 310 is disposed in the seating groove 113, and the cover part 120 is stacked and disposed thereon.

Thereafter, as shown in FIG. 7C, the first bent portion 136 is bent in the direction in which the cover portion 120 is stacked.

As the first bent portion 136 is bent, the second bent portion 137 is disposed adjacent to the cover portion 120, and the elastic portion 138 is in contact with the cover portion 120. It becomes more and more compressed.

When the bending of the first bent portion 136 by the external force is completed, the cover portion 120 is in close contact with the other surface of the bus bar 310 by the elastic restoring force generated while the elastic portion 138 is compressed. As a result, the bus bar 310 is tightly coupled between the cover part 120 and the bottom part 111.

As described above, in the second embodiment, by bending the fastening part 130 without the bolt 131 or the nut 132, the bus bar 310 may be easily coupled to the bus bar coupling part 100.
