High-voltage high-power servo controller busbar

Abstract

The invention provides a high-voltage high-power servo controller busbar. The busbar comprises a positive busbar (1), a negative busbar (5), upper insulating stand columns (3), lower insulating stand columns (2), an insulator (4) and an insulating support (6), the positive busbar (1) is used for connecting and conducting the positive electrodes of the components, and the negative busbar (5) is used for connecting and conducting the negative electrodes of the components; a plurality of pins respectively extend out of the positive busbar (1) and the negative busbar (5) and are used for conducting components and supplying power to the components; the insulator (4) is used for separating the positive busbar (1) from the negative busbar (5) to prevent short circuit caused by connection of busbars with different poles; the upper insulating stand columns (3) and the lower insulating stand columns (2) are used in pairs to support and fix the busbar; and the insulating support (6) is used for supporting and fixing a pin at the end part of the busbar, and a hole is formed in the insulating support (6) and is used for being connected and fixed with the main shell. Wiring is simplified, the cost is reduced, and the reliability is high.

Description

technical field [0001] The invention belongs to the technical field of spacecraft control, and in particular relates to a reliable bus bar of a servo controller. Background technique [0002] With the development of spacecraft control technology towards high precision and intelligence, there are more and more components inside the controller, and the wiring is becoming more and more complicated. In the preparation work, the time cost and price cost brought by the production of cables , labor costs, and reliability issues cannot be ignored. Excessive and long cables will add additional resistance and inductance to the system, causing the electrical circuit to fail to achieve the expected function, especially in environments where large-capacity capacitors are used.

Problems solved by technology

[0002] With the development of spacecraft control technology towards high precision and intelligence, there are more and more components inside the controller, and the wiring is becoming more and more complicated. In the preparation work, the time cost and price cost brought by the production of cables , labor costs and reliability issues cannot be ignored. Too many and too long cables will add additional resistance and inductance to the system, causing the electrical circuit to fail to achieve the expected function, especially in environments where large-capacity capacitors are used.

At the same time, a large number of terminals take up a lot of space, and it is more difficult to realize wire welding in the controller, which cannot adapt to the complex installation environment inside the controller.

In addition, it is extremely difficult to achieve a one-to-many electrical connection using cables

In the assembly process, the complex wiring work puts high demands on the assemblers. Even so, there is a high risk of wiring errors. The damage of components and the failure of the controller will bring higher development costs.

The outer diameter of the integrated multi-strand cables is difficult to estimate, making it difficult to accurately reserve the position and path for the cables in the early design, which can easily lead to crowded cables and small-radius bends during installation, both of which can easily lead to The damage of the cable brings extremely high unreliability factors to the system
