DETAILED DESCRIPTION OF THE INVENTION Hereinafter, a switchboard connecting apparatus according to the present invention will be described with reference to the drawings.

1 is a perspective view showing a connection device for a switchboard according to the invention, Figure 2 is a cross-sectional view showing a connection device for a switchboard according to the invention.

The switchboard connection apparatus according to the present invention basically has a bus bar 100 and a connection member 200 fixed to one side of the bus bar 100 and a charity bus bar fixed to the other side of the connection member 200. It consists of 300.

The bus bar 100 is one side connected to the output of the parking short-circuit in the switchgear to induce power, has a rectangular bar or panel shape formed with a first spiral hole 101 at a predetermined interval along the longitudinal direction, It is connected to the charity bus bar 300 through the connection member 200 described in detail below.

The connection member 200 is for electrically connecting the busbar booth 100 and the charity busbar 300 to each other. For this purpose, the first cylindrical part 210 coupled to the busbar busbar 100 and the own ship The second cylindrical portion 220 is coupled to the busbar 300.

The first cylindrical portion 210 has a cylindrical shape in which one side is opened, and a first connecting ring 211 is provided at an inner central portion of the other side, and an outer circumferential surface thereof is the first spiral hole 101 of the bus bar 100. As it has a structure that is coupled to the spiral to maintain a bus bar 100 fixed state.

The second cylindrical portion 220 has the same shape as the first cylindrical portion 210, that is, a second connection having a cylindrical shape with one side open to the inner central portion of the other side facing the first connecting ring 211. As the ring 221 is provided and the outer circumferential surface is helically coupled to the second spiral hole 301 formed in the charity busbar 300, the ring 221 is fixed to the charity busbar 300. It has a size that can be inserted into the first cylindrical portion (210).

Herein, the connection structure between the first and second cylindrical portions 210 and 220 may include the first and second abutments 212 and 222 provided at the first and second connection rings 211 and 221 provided therein, respectively. It is made by interposing a spring 10 between the first and second advents 212 and 222, and according to such a structure, the first or second cylindrical portion 210 or 220 is the bus bar 100 or the own ship. As the spiral is coupled to the busbar 300, the spring 10 is not twisted even when each cylindrical portion is rotated, and the busbar 100 and the charity busbar 300 are within the elastic force or the restoring force of the spring 10. It may be spaced apart or in close contact with each other.

The charity bus bar 300 is connected to the bus bar 100 to supply the power distributed to the auxiliary circuit breaker in the switchboard, and the first cylindrical part 210 is the first spiral hole of the bus bar 100. It has a rectangular bar or panel shape in which the second helix hole 301 is formed to helix coupled to the outer circumferential surface of the second cylindrical portion 220 that can be drawn out of the first helix hole 101 in the state fixed to the 101, As it may be coupled to the second cylindrical portion 220 and then may be in close contact with the busbar 100 by the restoring force of the spring 10, the busbar 100 is electrically connected to the busbar 100 by the connecting member 200. In addition to being connected, it can be reconnected in a state spaced apart from the bus bar 100 through the elastic force and the restoring force of the spring 10, and consequently, the connection part with the bus bar 100 by absorbing an external shock such as an earthquake. This will not be broken.

In addition, on the other side of the first and second cylindrical parts 210 and 220, that is, the center of the outer side of the closed surface, the grooves 213 and 223 having a positive shape are formed, respectively, so that the first and second tools 2 Cylindrical portion (210, 220) to facilitate the rotation in the first and second spiral holes (101, 301), more specifically, the bus booth bar 100 and the charity busbar 300 Is inserted into the first spiral hole 101 on the opposite side to which the second contact portion 101 is contacted, and then the second cylindrical portion 220 having a diameter smaller than that of the first cylindrical portion 210 is inserted. After fixing by rotationally coupling to 101, the second cylindrical portion 220 penetrating through the first spiral hole 101 is pulled to rotate in part to the second spiral hole 301 of the charity bus bar 300 to be fixed. Installation may be completed by rotating the second cylindrical portion 220 with a driver in one state.

Furthermore, in order to improve work efficiency when the plurality of connection members 200 are installed in the busbar bar 100 and the charity busbar 300, the busbar bar 100 and the charity busbar 300 may be replaced. A gap maintaining member (not shown in the drawing) may be used to space a predetermined distance from each other, and thus, each time the connection member 200 is installed, the bus bus bar 100 and the charity bus bar 300 may be separated by external force. When the second cylindrical portion 220 is exposed from the bus booth 100 in the spaced apart space, the second cylindrical part 220 is pulled and connected according to the mentioned process of installing the charcoal booth 300. Installation of the member 200 is completed.

In addition, a plurality of departure preventing grooves 214 are formed in the inner circumferential surface of the first cylindrical portion 210 along the longitudinal direction, and a protruding piece inserted into the detachment preventing groove 214 at one end of the outer circumferential surface of the second cylindrical portion 220. 224 is provided to prevent the separation of the second cylindrical portion 220 from the first cylindrical portion 210 as much as possible. In this case, the first and second cylindrical portions 210 and 220 are individually separated. Since the second cylindrical portion 220 is coupled to the second spiral hole 301 in the process of fastening the first cylindrical portion 210 to the first spiral hole 101 because it cannot be rotated.
