Integrated structure and integrated installation method of interconnection bar and printed circuit board

Abstract

The invention discloses an interconnecting strip and printed-circuit board integrated structure and an integrated installing method. The interconnecting strip and printed-circuit board integrated structure comprises a printed-circuit board, an insulating supporting part, an interconnecting strip and a bus bar. A plurality of grooves are formed in the insulating supporting part at intervals, a plurality of sections of bus bar bolt holes are formed inwards in the outer side edge of the insulating supporting part, the bus bar bolt holes correspond to and are communicated with the grooves, and each groove is internally and vertically provided with a through hole. The interconnecting strip is formed by bending a first connecting strip and a second connecting strip, the first connecting strip penetrates through the through holes to be connected with the printed-circuit board, and the second connecting strip is arranged inside the grooves of the insulating supporting part. The bus bar is connected with the second connecting strip through a fastener. According to the interconnecting strip and printed-circuit board integrated structure and the integrated installing method, cable connection between the bus bar and the printed-circuit board is omitted, installation is reliable and convenient, the installation space is effectively saved, the electric assembling time is shortened, the electric assembly difficulty is lowered, and the whole module is lightened.

Description

technical field [0001] The invention relates to the field of spacecraft power supplies, in particular to an integrated structure of an interconnection bar and a printed circuit board and an integrated installation method. Background technique [0002] Improving the power density of power supply controllers is the development trend of spacecraft power supplies today. Compared with previous spacecraft, current power supply controllers have higher requirements in terms of volume, weight, heat consumption, and mechanical properties. Therefore, in the design process of the power controller, the relationship between the controller structure and the printed circuit board and power circuit transmission should be fully considered. In the design of a modular power controller, how to achieve effective high-power transmission between each module will determine whether the entire system can operate efficiently. [0003] At present, in the high-power transmission design of the modular po...

Problems solved by technology

This method uses wires as the final connection medium between the main circuit and the bus bar, which can well realize the interconnection function between each module and the bus bar. However, due to restrictions on safety, derating, and device layout, the wiring of the power module wires Complicated and human-influenced, these will inevitably lead to increased weight of the controller, long assembly time, and difficulty in debugging and disassembly
