This programme adopts single cord as connecting line, so just makes the connection between upper clip, lower clamping piece and single cord very firm.In addition, because this programme has adopted the setting of ramp and lower inclined plane especially, make the displacement that is not easy to produce mutual left and right directions between upper clip and lower clamping piece.The angle of inclination of this programme refers to the angle between ramp (lower inclined plane) and horizontal plane.
Preferably, the angle of inclination of described ramp and described lower inclined plane is 20 °.
Preferably, described single cord comprises a core and a coating that is coated on described core outside, and the material of described core is T2 red copper, and the material of described coating is tin.By the setting of coating, increase the corrosion resistance of single cord, antioxygenic property.The Chinese trade mark corresponding to T2 red copper is T2, and the international trade mark is C1100, belongs to current material.
Preferably, the diameter of described single cord is 0.289 inch (7.3406 millimeters).
Preferably, the material of described upper clip and described lower clamping piece is copper.
In the utility model, above-mentioned optimum condition can combination in any on the basis that meets this area general knowledge, obtains each preferred embodiment of the present utility model.
Positive progressive effect of the present utility model is: by utilization of the present utility model, reduced capacitor complete set of equipments because connect overheated, the clean electrical distance in unreliable junction of causing and the hidden danger causing such as reduced, increased reliability and the fail safe of capacitor.
