Wherein, said contact both sides are provided with the contact chimb.
Wherein, the quantity of said contact knife is 2, and the quantity of said groove is 2.
Wherein, the quantity of said contact knife is 3, and the quantity of said groove is 3.
The beneficial effect of the utility model:
The height of chimb can be higher than contact, and then chimb has further increased the contact knife contact area, and the both sides of chimb are provided with reed.Chimb and reed play a protective role to contact, also contact knife are played spacing effect simultaneously.
