Further improvement of the present invention is: described lug plate, inductance and electric capacity quantity are 2, and are symmetrically distributed in the upper surface of body respectively, spaced, with the upper surface of body to have the notch being used for fixing former three suitable.Intrinsic end cap shape is used for fixing EMC element, makes mechanical strength higher, more firmly.The symmetrical structure scope of application is wider, and versatility is stronger.
Further improvement of the present invention is: described copper sheet one is in peach-shaped, and described top apex place is earth point, and to reserve opening suitable with body upper surface.Structure is simple, is convenient to welding, and does not affect the connection of other elements.
Further improvement of the present invention is: described copper sheet one is identical with the quantity of electric capacity with inductance with the quantity of copper sheet two, and is symmetrically distributed in the outer ring of annulus, corresponding with the installation site of inductance and electric capacity.Decide the shape of conducting strip according to EMC number of elements, realize versatility preferably, manufacturing process is simple.
Further improvement of the present invention is: described intercell connector cut-off part minimum spacing meets >=0.8mm, effectively avoids short circuit problem.
Further improvement of the present invention is: the rectangular shape of described intercell connector, more simple relative to arc intercell connector processing technology, cuts off more convenient.
The invention has the beneficial effects as follows: EMC element and carbon brush be not same, in motor operation course, carbon brush spot temperature can be higher, and EMC element and carbon brush be not same, the higher temperature of carbon brush can not affect EMC element, can reduce EMC component temperature class requirement.
