The depth of groove little by little increases deep, formation rigid-flexibility transition section towards right-hand member direction；The bus-bar body left part lower end is formed with first
Breach, two backing plates are installed in the first breach, and two backing plates are separately fixed in two cavitys, two backing plate lower ends are made
There is the second breach to be matched with the first breach, two contact wire's joint wire clamps are disposed side by side on the first breach and the second breach
In, and respectively positioned at the lower section of two backing plates, and the jaws of contact wire's joint wire clamp bottom is corresponding with the contact line jaw,
And by the second breach both ends of the surface limit contact wire's joint wire clamp along line direction vibration.
The side lower of the bus-bar body right part rigid-flexibility transition section is equally spacedly formed with through hole,
The through hole is provided with bolt between the groove on each through hole.
The section external dimensions of the bus-bar body is consistent with the section external dimensions of existing single line bus-bar.
The utility model has the advantage that compared with prior art and effect：
1) overall structure is simple, consistent with existing single line bus-bar suspension size, is easy to the replacing and installation of existing line.
2) current-carrying capacity is big and the method for clamping of double joint contact line is reliable and stable, double jaw distances and flexible double contact line distances
It is identical, line eccentric wear can be avoided contact with, reversed.
3) gradual conversion of the rigidity to flexibility is realized, makes motorcycle pantograph more steady by electricity in rigid-flexibility transition area,
Extend pantograph service life, reduce the abrasion of joint contact line, improve and flowed.
4) body uses aluminium alloy extruded one-shot forming, and dimensional accuracy is high, mature production technology, simple.
