A kind of flexible overlapping bus row; Butterfly pad and transformation of the way screw that it comprises anodal copper bar, negative pole copper bar and connects two copper bars; Described anodal copper bar, negative pole copper bar form by plurality of thin sheet copper coin stack combinations; Described butterfly pad, transformation of the way screw connect thin slice copper coin group, and described anodal copper bar, negative pole copper bar offer busbar connection hole.
Detailed technical scheme: a kind of flexible overlapping bus row; Butterfly pad and transformation of the way screw that it comprises anodal copper bar, negative pole copper bar and connects two copper bars; Described anodal copper bar, negative pole copper bar form by plurality of thin sheet copper coin stack combinations; Described butterfly pad, transformation of the way screw connect thin slice copper coin group; Described anodal copper bar, negative pole copper bar offer busbar connection hole, and the outer surface of described anodal copper bar, negative pole copper bar has sticked dielectric film, and described laminar copper coin is the high flexibility sheet copper.
Than solution of the prior art, the utility model advantage is:
1. the described flexible overlapping bus of the utility model row is by anodal copper bar, negative pole copper bar and the butterfly pad that connects two copper bars, and transformation of the way screw constitutes.Compare the inductance that can effectively reduce by two interpolars with single thicker copper coin or flexible one pole copper; And being flexible coupling of flexible overlapping bus row can improve the shock resistance of connection; Eliminate thermal expansion to connecting loosening influence, and this flexible overlapping bus row improves the area of dissipation of copper bar greatly, made this copper bar can pass through bigger electric current; Increase the utilance of copper coin, reduced the waste of resource;
2. the flexible overlapping bus row that the utility model provided connects laminated bus bars; Structure is very compact; It not only can possess characteristics such as normal stack bus row's Low ESR, low inductance; And can reduce system noise and electromagnetic interference and radio frequency interference, and realized flexibly connecting and do not have thermal expansion and be connected between laminated bus bars, improved connective stability.
