Description

Technical Field

[0001] This utility model relates to busbar connection structure, specifically to a high-voltage, high-current busbar connection structure and an electronic device containing the structure. Background Technology

[0002] In high-voltage power distribution cabinets, the output of high voltage and high current requires the parallel connection of multiple modular power supplies. The current is mainly carried by copper busbars. When the voltage is high (greater than 1000V), traditional copper busbars are used as carriers for current carrying. However, a large creepage distance is required between copper busbars of different polarities, which occupies a large volume. But with the development of needs, users require power density to be higher and power volume to be smaller. In addition, there are many electrical components in high-power cabinets and the connections are complex. In order to output a larger current in a limited space, increase insulation performance, and improve the reliability of power distribution equipment, it is necessary to improve the busbar connection structure for high voltage and high current. Summary of the Invention

[0003] This utility model is proposed in view of the above-mentioned problems, and its purpose is to provide a new type of high-voltage high-current busbar connection structure and electronic equipment containing the structure, so as to realize high-current connection in a compact space and effectively and reliably transmit high current.

[0004] To achieve the above objectives, this utility model provides a novel high-voltage, high-current busbar connection structure, the technical solution of which is as follows:

[0005] A high-voltage, high-current busbar connection structure includes an electrical connector, a busbar strip, a busbar, and a cable. The busbar strip is characterized by threaded holes at both ends, and the busbar is a stacked busbar containing at least two layers of busbar plates of different polarities. Each layer of busbar plate has an insulating pad on its surface, and each layer of busbar plate has corresponding electrical connection terminals and mounting holes. The cable is fixedly connected via the terminals, and the busbar strip is fixedly connected via screws to the threaded holes of the busbar strip through the mounting holes. The other end of the busbar strip is fixedly connected to the electrical connector via a screw through a threaded hole.

[0006] Furthermore, all the different polarity busbars mentioned are made of copper.

[0007] On the other hand, this utility model also provides an electronic device, including a chassis and a high-voltage, high-current busbar connection structure as described in the above solution.

[0008] Furthermore, the electrical connector in the high-voltage, high-current busbar connection structure is fixed to the side panel of the chassis; the stacked busbar in the high-voltage, high-current busbar connection structure is also fixed to the side panel of the chassis via insulating support columns, ensuring a certain spatial distance between the stacked busbar and the chassis, thereby improving the insulation performance between the stacked busbar and the chassis.

[0009] The beneficial effects of adopting the above-described technical solution in this utility model are as follows:

[0010] This high-voltage, high-current busbar connection structure adopts a stacked busbar design to solve the input and output current convergence of multiple current modules, saving space. The stacked busbar, being an integrated type, features high reliability and high insulation characteristics. The busbars are connected to the stacked busbars using screws, improving ease of maintenance and operation. The overall structure is rationally designed and convenient to use. Within a limited space, it enables high-voltage, high-current convergence while ensuring insulation performance and solving the problem of connecting multiple power supplies.
