[0002] In the power system, the busbar connects the various current-carrying branch circuits in the distribution device, and plays the role of collecting, distributing and transmitting electrical energy.

[0003] However, in the prior art, when the distance is far and the busbar length is insufficient, and it is necessary to splice with the remaining busbars, the busbars can only be welded and then continued to be laid, so that the welding process is long and the welding process may be unstable, which is not conducive to practical application. Utility Model Content

At the same time, the welding process may also be unstable, which is not conducive to practical application.

[0005] The technical solution of the utility model is as follows: a bus duct connection structure that is easy to expand, including a connecting pipe, a connecting block is fixedly connected to the inside of the connecting pipe, a clamping block is equidistantly fixedly connected to one side of the connecting block, a connecting piece is equidistantly fixedly connected to the side of the connecting block away from the clamping block, the connecting piece is used in conjunction with the clamping block, a nut is fixedly connected to one side of the clamping block, a bolt is rotatably connected to the inside of the connecting pipe, the bolt is slidably connected to the clamping block, and the bolt is threadedly connected to the nut.

[0006] Through the above technical solution, when the busbar distance is not long enough, one end of the device is fixed to the busbar, and the connecting piece is inserted into the interior of the clamping block. The bolt is turned so that the nut drives one side of the clamping block to shrink, so that the clamping block can fit tightly with the corresponding connecting piece, so that the connecting piece can be electrically connected to the clamping block, and then quickly connected, while avoiding the complicated operation and uncertainty of welding.

[0007] As a preferred embodiment, threaded holes are provided on both sides of the connecting pipe, a first limiting hole is provided on the outer side of the clamping block and on one side of the nut, and a second limiting hole is provided on the outer side of the connecting plate. The first limiting hole, the second limiting hole and the threaded hole are used in conjunction with each other.

[0008] Through the above technical solution, by passing the limiting screw through the threaded block and the first limiting hole and the second limiting hole in sequence, the connecting piece and the clamping block can be fixedly connected and cannot be separated.

[0009] As a preferred embodiment, a first flange is fixedly connected to the outer side of the connecting pipe, and a second flange is fixedly connected to the outer side of the connecting pipe and located on one side of the first flange, and the first flange and the second flange are used in combination.

[0010] Through the above technical solution, the first flange and the second flange can be connected to each other through screws.

[0011] As a preferred implementation, one end of the connecting pipe is fixedly connected to a sealing strip, and a sealing groove is provided on a side of the connecting pipe away from the sealing strip.

[0012] Through the above technical solution, the sealing groove and the sealing strip are used in conjunction with each other, thereby increasing the sealing performance between the connecting pipes.

[0013] As a preferred implementation, the connecting piece is electrically connected to the corresponding clamping block inside the connecting block.

[0014] Through the above technical solution, the connecting piece is electrically connected to the corresponding card-connecting block, so that the transmission operation can be performed thereon.

[0015] As a preferred implementation, the bolts, nuts, connecting blocks and connecting pipes are all made of insulating materials.

[0016] Through the above technical solution, since the bolts, nuts, connecting blocks and connecting pipes are all made of insulating materials, the possibility of leakage is avoided.

[0017] Compared with the prior art, the advantages and positive effects of the utility model are:

[0018] In the utility model, when the distance between the busbars is not long enough, one end of the device is fixed to the busbar, the connecting piece is inserted into the inside of the clamping block, and the bolt is rotated so that the nut drives one side of the clamping block to contract, so that the clamping block can be closely fitted with the corresponding connecting piece, so that the connecting piece can be electrically connected to the clamping block, and then the connection is quickly made, while avoiding the complex operation and uncertain factors of welding;

[0019] By passing the limiting screw through the threaded block and the first limiting hole and the second limiting hole in sequence, the connecting plate and the clamping block can be fixedly connected so that they cannot be separated. The sealing groove and the sealing strip are used in conjunction to increase the sealing between the connecting pipes. At the same time, the first flange and the second flange can be connected to each other by the screw. BRIEF DESCRIPTION OF THE DRAWINGS
