Stack bus bar, claims again composite bus bar, and low-inductance bus is that a kind of multi-layer compound structure connects row, has Low ESR, anti-interference, good reliability, the succinct feature of connection.
Stack bus bar is normal adopts a kind of inserting terminal syndeton, realize more convenient with other components and parts, be connected more reliably, but this will solve the problem that inserting terminal is connected with stack bus bar.Under prior art, often adopt the mode of soldering that inserting terminal is welded on stack bus bar, stack bus bar red copper used belongs to the material that thermal conductivity coefficient is very large.The Welding Structure of traditional stack bus bar inserting terminal is as Fig. 5, both positive and negative polarity copper bar is drawn respectively a welding pin, one end of welding pin is connected with copper bar, the other end and copper bar disconnect, and laterally have 2 apertures in welding pin, and the anodal copper bar of take is as shown in Figure 6 example, welding pin place has aperture and is respectively h1, h2, h1 hole from copper bar close to, h2 hole from copper bar away from, and reduced heat-conducting section between h1 hole and h2 hole.During actual welding, because h2 hole can complete welding from the thermally conductive pathways of copper bar away from slightly reluctantly, and h1 hole due to from copper bar too close to, heat-conducting section is larger, the temperature of pad is delivered to rapidly on copper bar scatters and disappears, and is difficult to reach at pad place welding fusing point; If improve the temperature at pad place, because master row insulating film has certain heat resisting temperature, during welding, heat transmission easily makes dielectric film be subject to high temperature to damage inefficacy.
Summary of the invention
The utility model object is to provide a kind of Welding Structure for stack bus bar inserting terminal, guarantees that the performance of stack bus bar is not damaged when meeting welding requirements.
In order to solve these problems of the prior art, the technical scheme that the utility model provides is:
A kind of Welding Structure for stack bus bar inserting terminal, stack bus bar comprises anodal copper bar, negative pole copper bar, external insulation film, intermediate insulating film, intermediate insulating film is arranged between anodal copper bar and negative pole copper bar, external insulation film sticks on anodal copper bar, the outer surface of negative pole copper bar, external insulation film and intermediate insulation film edge press together realizes edge sealing, on the both positive and negative polarity copper bar of laminated bus bars, be provided with welding pin, in welding pin, be provided with jack, inserting terminal is with needle-like pin, the needle-like pin of inserting terminal is through the jack in welding pin and be close to copper bar setting, both sides in the welding pin of each copper bar are respectively equipped with vertical bar shaped pin, vertical bar shaped pin is connected with copper bar, between the remainder of welding pin and copper bar, there is space.
After this stack bus bar hot pressing, implement again welding, while implementing welding, pad heat can not scatter and disappear rapidly, when pad reaches welding fusing point and completes welding, the temperature being delivered on copper bar can be higher than the tolerable temperature of laminated bus bars upper nonconductive Film, can not damage dielectric film, when guaranteeing welding effect, prevent the problems such as dielectric film damage yet, improve product quality.
The pin widths W of the vertical bar shaped pin that in addition, draw welding pin both sides and pin length L are according to the requirement adjustment of stack bus bar current capacity.The vertical bar shaped pin that draw welding pin both sides meets current-carrying requirement, when guaranteeing welding effect, also can not affect the current capacity of stack bus bar.
Than solution of the prior art, the utility model advantage is:
The utility model has been described a kind of Welding Structure for stack bus bar inserting terminal, this Welding Structure is equivalent to welding pin independent, make to have certain interval between welding pin surrounding and copper bar, prevent scattering and disappearing fast of pad place heat, only by vertical bar shaped pin, this welding pin and copper bar are coupled together, by make welding pin meet the current capacity of stack bus bar to the length and width adjustment of described vertical bar shaped pin, guarantee that Welding Structure of the present utility model can not cause harmful effect to stack bus bar performance simultaneously.So, can guarantee that the temperature of welding pin can not scattered and not disappeared rapidly, make to reach fast welding fusing point requirement, and busbar hot pressing implements welding after closing again, do not damage dielectric film, do not affect the current capacity of inserting terminal.
