Embodiment 1

[0033] refer to figure 1 , there are two layers of copper plates, namely positive copper plate 2 and negative electrode copper plate 5, the size and thickness of the copper plate depends on the current passing through and the installation position of other components, usually the thickness is 0.8-10.0 mm, and the material is T2 Pure copper with semi-hardness, quarter-hardness or zero-hardness copper bars; copper plates are punched, bent, stretched, deburred, input / output terminals pressed, and welded with a thickness of 0.1 to 0.2 mm. Flexible copper bars 1 and 7 (also known as soft connections) made of one-hardness or zero-hardness copper foils, electroplating and other processes ensure that the input / output and external dimensions meet the requirements of connection and installation;

[0034] Between the positive electrode copper plate 2 and the negative electrode copper plate 5, a double-sided adhesive-containing insulating film 4 is used, that is, a film (such as PET) coat...

Embodiment 2

[0036] refer to figure 2 , is a single-layer flexible and rigid bus bar, which is connected together by copper plate 9 and flexible copper bar 8 by welding (such as silver welding, ultrasonic welding, tin welding, etc.), and the front and back of copper plate 9 are both made of single-layer The adhesive insulating film 10 is formed by thermally pressing and bonding a single layer of a film (such as PET) coated with a thermosetting epoxy resin adhesive.

Embodiment 3

[0038] refer to image 3 , is a soft-hard composite bus bar, which includes multiple layers arranged in sequence, namely: single-sided adhesive insulating film 11, flexible copper bars 12 and copper plates 13 welded on the same layer, double-sided adhesive insulating film 14, and welded on the same layer Flexible copper bar 15 and copper plate 16, double-sided adhesive insulating film 17, flexible copper bar 18 and copper plate 19 welded on the same layer, and single-sided adhesive insulating film 20, and then put the above multi-layers in order according to the process requirements In the pressing mold, pressurize and heat in the hot press, and solidify the epoxy resin according to the pressurized heating, heat preservation and cooling curves, and form a soft-hard combination similar to printed circuit boards at room temperature after cooling. bus bar.

Abstract

The invention discloses a flexible and rigid composite busbar and a manufacturing process. The flexible and rigid composite busbar comprises at least one layer of copper plate and flexible copper bars which are welded on an input end and an output end of the at least one layer of copper plate through a welding process, wherein the copper plates are separated from each other through double-sided glue-containing insulating film; the outer surfaces of the outermost copper plates are coated with a single-sided glue-containing insulating film; and the copper plates and the insulating films are laminated together through a heat fusion process, then arranged in a fixed clamping device and placed in a heat fusion pressing machine, and superimposed together after being subjected to pressurization, heating, heat preservation and cooling according to a process curve pattern. According to the flexible and rigid composite busbar and the manufacturing process, the copper plates are connected with the flexible copper bars to form the flexible and rigid composite busbar; by utilizing the scalability and rotatability of the flexible copper bars, the field assembly and the telescopic deformation caused by heating of the busbar can be freely adjusted so as to meet the requirements of connection in different directions.

Description
