Description

[0001] STRUCTURE FOR BONDING BUS BARS [0002]

The present invention relates to a structure for joining a bus bar.

Distribution boards are electric devices that distribute electricity to large residential areas such as factories, buildings and apartments, and also prevent electric accidents by blocking overcurrents and protect load devices.

The conventional distribution board includes a main wiring breaker capable of drawing power from the power source side and interrupting the circuit, a plurality of main bus bars connected to the load side terminals of the main wiring breaker, a plurality of branching portions for distributing power from the main wiring breaker to the load side And a branch booth connected between the main busbar and the terminal portion of the branching interrupter for branching the current path from the main busbar.

Such conventional distribution boards require so-called tapping (TAP) processing for forming a thread surface on the inner circumferential surface of the hole and for drilling holes for screwing the main busbar and the branch busbar to each other. Further, The process is complicated and mass production is difficult.

Further, since the conventional distribution panel requires a large number of manual processes, it takes a long time to manufacture and requires a lot of manpower, resulting in an increase in cost. In addition, the conventional distribution board has a problem in that it can not flexibly cope with such changes due to hole machining and tapping of the main bus bar and branch booth bars in the case of a change such as addition of circuit during use, manufacture, or field installation .

1 is a view schematically showing a structure for joining a bus bar according to an embodiment of the present invention. FIG. 2 is a side view showing a state in which a bus bar bar, a charger bus bar, and a bushing are coupled to each other in the structure for joining a bus bar according to an embodiment of the present invention. Figure 3 is a more detailed view of a bushing in a structure for joining a bus bar according to an embodiment of the present invention. 4 is a side view of a circuit breaker connection coupled to a terminal of a circuit breaker in a bus bar coupling structure according to an embodiment of the present invention.

1 to 4, a structure 1000 for joining a bus bar according to an embodiment of the present invention includes a bus bar bar 100, a charger bus bar 200, and a bushing 300, And may further include a breaker connection part 500.

Meanwhile, in the case of a distribution board, a plurality of circuit breakers 10 and 20, a structure 1000 for a bus bar coupling, a bus bar support board, and the like may be included, and the components of such a distribution board may be embedded in the enclosure, have. And, the enclosure can include a bottom plate on which the components are disposed and an upper lid that is connected to the bottom plate and covers the components.

The bus bar bar 100 is a part extending in one direction and is electrically connected to the load side terminal part of one of the circuit breakers 10. The bus bar bar 100 is formed of an electrical conductor and is arranged to correspond to an alternating current phase and a neutral (N), respectively. For example, the bus bar bar 100 may be disposed so as to be spaced apart from each other for R-phase, S-phase, T-phase and neutral (N) of alternating current.

The charger bus bar 200 is formed to extend in a direction intersecting the bus bar bar 100 and is disposed so as to correspond to the power source side terminal portion of the other breaker 20 and is connected to the other bus breaker 20, And functions to electrically connect the bar 100.

For example, if the other breaker 20 is a three-phase four-wire breaker, four charger bus bars 200 are connected, and if the other breaker 20 is a three-phase three-wire breaker, The bar 200 may be connected.

The bushing 300 is interposed between the main bus bar 100 and the main bus bar 200 to maintain a distance between the main bus bar 200 and the main bus bar 100, And the remaining portion of the bushing 300 may be in contact with each other through the bushing 300 and the remaining portions may be spaced apart from each other by a distance corresponding to the thickness of the bushing 300 between the main bus bar 100 and the main bus bar 200 Can be maintained.

As described above, since the bus bar assembly 100 according to the present embodiment is spaced apart from the bus bar bar 100 by the bushing 300, the structure can be more stably The bus bars 100 and 200 can be coupled.

Also, it is possible to easily maintain the space without bending the booth bars 100 and 200 separately from the booth bar 100 and the booth bar 200 at a predetermined interval.

The bushing 300 may be formed to be larger than the width of the charger booth bar 200 so that the insertion groove 310 into which the charter booth bar 200 can be inserted may be formed have.

For example, as shown in FIG. 3, both ends of the bushing 300 may be protruded to form an insertion groove 310 in which the interior of the bushing 300 is embedded. As shown in FIG. 2, The width of the charger bus bar 200 can be inserted into the insertion groove 310 in an engaging manner.

As a result, it is possible to restrict the movement of the charger bus bar 200 in the width direction with respect to the charger booth part 100, so that the reliability of the combination of the bus bars 100 and 200 can be further increased.

In the bus bar fitting structure 1000 according to the present embodiment, the bus bar bar 100, the charger bus bar 200, and the bushing 300 may be coupled to each other through screws 400 in the longitudinal direction. That is, the screw 400 can be coupled in a longitudinal direction while sequentially passing through the charger bus bar 200, the bushing 300, and the bus bar bar 100.

As a result, the bus bars 100 and 200 can be easily coupled through a simpler structure, and disassembly and replacement can be made easier.

The breaker connection part 500 is a part bent in a downward direction from the terminal of the circuit breaker 10 and coupled to the end of the bus bar 100. The breaker connection part 500 can couple the breaker 10 and the bus bar 100 to each other Lt; / RTI >

4, the circuit breaker connection part 500 is formed to be bent downwardly so that the circuit breaker connection part 500 can be bent in a downward direction without separately machining the bus bus bar 100, It may be easy to install the battery 200.

5 is a perspective view showing a structure for joining a bus bar according to another embodiment of the present invention.

5, in the structure 2000 for joining a bus bar according to another embodiment of the present invention, the bushing 300 is formed such that the bus bar bar 100 and the charger bus bar 200 extend in the extending direction It can be inserted through.

That is, the bus bar bar 100 may be installed through the bushing 300 along one direction, and the charger bus bar 200 may be installed through the bushing 300 along the direction intersecting the direction.

This makes it possible to more reliably and firmly couple the busbars 100 and 200 with each other, thereby further enhancing the reliability of the busbars 100 and 200.

The main configuration of the bus bar fitting structure 2000 according to another embodiment of the present invention is the same as the main configuration of the bus bar fitting structure 1000 according to an embodiment of the present invention except for the above- The detailed description of the overlapping portions will be omitted.
