Abstract
The utility model discloses a bent stacked bus bar, which comprises at least one bending structure and is composed of more than one copper bar layers and insulating layers superposed in sequence, wherein the insulating layers are arranged between the outer layer of the bus bar and each copper bar layer, a segmental structure is arranged at the bending site of the bus bar, and the corresponding copper bars in the adjacent bus bar segments at two sides of the bending site are connected in series via connectors. The bus bar provided in the utility model is formed by connecting a plurality of bus bar segments, the connecting sites are the bending sites of the bus bar. When the stacked bus bar is brought into operation,, the connection of the bending sites can be realized in more than one way, such as connecting adjacent bus bar segments via bent connectors or directly and integrally bending the copper bar connection end pieces of the bending structures on the copper bars in the bus bar segments, thus, the bending structures of insulators need to be manufactured when the bent stacked bus bar is processed. The bent stacked bus bar provided in the utility model can reduce production cost, and simplify production process; and can prevent the insulating layers from being cracked and detached due to stress concentration.
Description
Technical field
The utility model relates to folded shape busbar technical field, and the shape busbar is folded in especially a kind of bending.
Background technology
Existing folded shape busbar mostly is plate shaped greatly, be with stacked in regular turn insulating barrier by conduction copper column with positioning action, positive copper bar, the negative stacked multilayer stack that forms of copper bar, and between conduction copper column and busbar, be provided with the insulation chock, in actual use, for being electrically connected of the limited automatically controlled product in implementation space, need be to plate shaped folded shape busbar bending, Chinese patent application 200410047021.5 discloses a kind of three-dimensional low-inductance bus, existing manufacture method is that the copper bar that bending is good and the good insulating barrier that is shaped are by superimposed pressures of design sequence layer, this integrally formed folded shape busbar in use, the insulating barrier of corner is concentrated owing to stress and is come off easily, and this folded shape busbar on the make needs special-purpose insulating barrier mould, and cost of manufacture is higher.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure, folded shape busbar of being convenient to connect.
The technical solution of the utility model is: the shape busbar is folded in a kind of bending, comprise at least one bending structure, by the copper bar more than one deck and insulating barrier is stacked according to the order of sequence constitutes, insulating barrier is arranged between outer and each layer copper bar of busbar, busbar is a segmental structure at bending part, and the corresponding copper bar in the adjacent busbar section on bending part both sides is serially connected by connector.
Described connector is made of a connector that is provided with on the corresponding copper bar and a connecting bolt that corresponding connector tightens together, and described connector is provided with the connecting hole that penetrates for bolt.
Described connector is the copper bar connection dististyle that is set up in parallel in the lath-shaped at busbar section edge, and it is bending structure that at least one group of copper bar arranged side by side wherein connects dististyle.
It is positive and negatively alternately to be set up in parallel that described copper bar connects dististyle.
The interface that the copper bar of the opposed polarity at least one group in the described copper bar connection dististyle connects dististyle is in Different Plane to form plug-in docking structure.
It is in the same plane that one group of copper bar on the busbar section in the described two adjacent busbar sections connects dististyle, and the connection of the copper bar on Dui Ying another busbar section dististyle is the alternatively up and down setting with it.
The utility model is that the busbar by the polylith segmentation connects and composes, the junction is the bending place of busbar, can adopt multiple mode to realize the connection of bending place in the specific implementation, such as connecting adjacent busbar with the bending connector, one bends out the copper bar connection dististyle of bending structure on the perhaps direct copper bar in the segmentation busbar, when folding the shape busbar, the processing bending just do not need to make the bending structure of insulator like this, since the technology comparative maturity of plate stack shape busbar, and bending connector or copper bar are also realized than being easier to.Therefore adopt structure of the present utility model can reduce manufacturing cost, simplify manufacture craft; Can stress yet do not concentrate and cause the cracking of insulating barrier to come off.
