Bus connection structure

Abstract

The invention provides a bus bar connection structure, which aims to solve the technical problems of guaranteeing the connection strength while preventing drop. In order to solve the technical problems, the technical scheme provided by the invention is that the bus bar connection structure comprises a first bus bar (1) and a second bus bar (2), and is characterized in that the first bus bar (1) and the second bus bar (2) are provided with a plurality of bosses (3) and a plurality of corresponding through holes (4) for tight fit, wherein at least two tight fit parts are arranged between each boss (3) and the corresponding through hole (4).

Description

technical field [0001] The invention relates to a connection structure of a bus bar. Background technique [0002] The so-called bus bar refers to the copper bar or aluminum bar that connects the main switch in the electric cabinet and the switches in each branch circuit in the power supply system. The connection between the space and the high-power components has the same function as the wire. The specific use of busbars or cables depends on the electrical occasion and environment. During the use of the existing busbars, multiple busbars will be stacked together. The reason why such a structure is used is that multiple terminals of circuit components such as IGBTs are on the same plane. In order to facilitate this The laminated busbar structure is used for the connection of components with similar terminals on a plane; and for the connection between each busbar in the laminated busbar, the main connection methods currently used are clamping, riveting, tight Coordination a...

During the use of the existing busbars, multiple busbars will be stacked together. The reason why such a structure is used is that multiple terminals of circuit components such as IGBTs are on the same plane. In order to facilitate this The laminated busbar structure is used for the connection of components with similar terminals on a plane; and for the connection between each busbar in the laminated busbar, the main connection methods currently used are clamping, riveting, tight Coordination and other connection methods; the busbar pressure riveting connection structure in the prior art has the following disadvantages: because the busbar is made of copper or aluminum plate, the material hardness is small, and it will be deformed when it is subjected to other external forces after connection, so the connection between the busbar cannot be guaranteed. between the connection strength, there will be falling off
