Fig.

The one-touch branch bus connecting device 300 is a connecting device for connecting the main bus 10 and the branch bus 20, and is a device for connecting the main bus 10 and the branch bus 20. The one- A connecting nut in which the nut 13 of Fig. 6 and the fixing spring 12 are coupled to the main bus bar 10 formed with grooves (grooves of C shape) on one side of the main bus bar 10 And is inserted into the groove of the L-shaped booth bar and fixed by the fixing spring 12.

Here, the main bus bar 10 is formed in a structure in which a side opening is formed in one side of an L-shaped bus bar.

The spring 12 is positioned between the groove inner side surface of the main bus bar 10 and the nut 13 and is larger than the hole of the nut 13 so that the nut 13 is fixed in the groove of the main bus bar 10.

The nut 13 is inserted into a side opened in the groove of the main bus bar 10 and has a hole in the same direction as the groove forming direction and has a larger diameter than the groove.

On the other hand, the branch bus bar 20 has a hole for connecting to the main bus bar 10 at the same position as the groove position of the main bus bar 10.

One-touch compression cam 31 and one-touch connection compression bolt 30 as shown in Figs. 7 to 8 are fixed by one-touch compression cam fixing pin 34 and an operation hole 40 of one- The spring safety cover 32 and the high-strength spring 33 are connected to each other

The one-touch branch bus connecting device 300 of the present invention is constructed by connecting the one-touch connecting bolt 30, the high-strength compression spring 33, the spring safety cover 32, the elliptical one- 34, and the one-touch connection nut is inserted into the groove of the L-shaped booth bar and fastened to the one-touch connection bolt 30

In order to solve the problems that have arisen in the prior art, the present invention has been made so that the main bus bar 10 is formed into an L-shaped bar shape and a C-shaped groove formed on one side, It is possible to provide a one-touch connection structure in which the temperature rise of the bus bar is suppressed as much as possible,

As described above, the main bus bar 10 is formed in the lower portion of the L-shaped bus bar so as to have a C-shaped groove, so that the connecting nut 13 of Fig. 6 can be fixedly connected Touch branch connection device 300 is connected to the connection point of the main bus 10 and the branch bus 20 by a constant pressure so as to be fixed at one-touch by fixing the main bus 10 and the branch bus 20 to the connection position of the branch bus 20, It prevents the overheating due to the connection failure by maintaining the constant connection state without loosening and also protects the internal devices of the distribution panel and prevents fire and accidents due to overheating

At this time, the main bus bar 10 is manufactured in a structure in which the vertical and horizontal bus bars are formed in the L-shaped bus bar and the C-shaped groove is formed. The spring 13 for inserting the nut 12) Install the lock.

After the branch bus bar 20 is installed, the high-strength compression spring 33 and the compression spring cover 32 are inserted and the connection bolt 30 is turned so as to be closed on the bottom surface of the C groove. When the connecting lever of the one-touch spring compression cam 31 is rotated by 90 degrees, the rotation is performed with the one-touch cam holding pin 34 as the center axis.

At this time, as the elliptical compression cam 31 compresses the spring 33 while rotating, the main bus 10 and the branch bus 20 are compressed and compressed by the compression cam 31 and the high-strength compression spring 33 .

The main bus line 10 is L-shaped, the front surface is fixed to a predetermined size, and when the capacity of the switchboard is increased, the capacity of the current is regulated by adjusting the size of the rear surface, so that it can be installed at a constant size regardless of the current size.

The connecting nut 13 that enters the C-shaped molding machine is of the form having a dry hair and an edge, and has a spring 12 on the bottom surface and a screw in the central hole to connect the connecting bolt

The spring safety cover 32 is provided at the both ends of the compression spring 33 and the main spring 10 and the branch bus 20 are connected to each other so that the spring safety cover 32 has sufficient strength at one- .

The head of the connecting bolt 30 is formed in a square or circular shape, and a hexagonal wrench and a + screwdriver can be used at the center, and a compression cam fixing pin 34 It is preferable that the hole is machined so that the one-touch spring compression cam 31 can be installed.

The fixing bolt 34 is provided at the intermediate hole of the connecting bolt 30 so that the one-touch spring compression cam 31 can be installed.

The high-strength compression spring 33 is compressed by the elliptical projecting portion formed at the position away from the center axis of the one-touch compression cam fixing pin 34 in the compression cam 31 so that the main bus bar 10 and the branch bus bar 20 are compressed, .

Thus, in the one-touch connection structure of the main bus line 10 and the branch bus line 20 of the switchboard (high and low voltage switchboard, transformer, motor, distribution board), the branch busbar 20 is connected to the main busbar 10, A nut 13 having a spring 12 is inserted into the C-shaped groove of the main bus bar 10 and fixed to a position to be connected. After the branch bus bar 20 is installed, the bolt 30 and the compression spring The compression spring 33 and the safety cover 32 are combined and lightly tightened. Then, when the connecting lever of the elliptical one-touch spring compression cam 31 is rotated by 90 degrees, the high-intensity compression spring 33 are compressed, the branch bus bar 20 is compressed and connected by one-touch.

By applying the one-touch connection method of screws and a spring-integrated type in this way, the branch bus bar 20 can be easily assembled, the connection part is not loosened even in vibration and wobbling, And the flow of current is improved.

At this time, since it is possible to connect the main bus bar 10 and the branch bus bar 20 without machining of the main bus bar, it is possible to easily assemble the non-professional barber to improve the productivity, reduce the manufacturing cost, improve the competitiveness, It can be expected to prevent the electric fire accident caused by the arc and overheating of the contact part caused by the contact, and to prevent damage to the power distribution board and property damage.
