Has reinforcement between the port of the tooth of the broach shape of the coil baffle plate on the described skeleton and skeleton chamber wall.

One end and the upper yoke of described train wheel bridge, arm-tie fasten as one by fastening bolt and nut, the other end of described lower plate, arm-tie and lower yoke fasten as one by fastening bolt and nut, insulating part is equipped with at the two ends of described fastening bolt respectively, described insulating part comprises insulation cushion and insulating case, insulation cushion is between the end of lower plate and fastening bolt, the periphery of fastening bolt also is with insulated tube, and insulating case is between fastening bolt and insulated tube.

Described train wheel bridge and lower plate all are the L type, and the upper surface of described train wheel bridge has screw, and lower plate has oval shape through hole.

The good effect that the utility model had is: because the upper and lower side of described skeleton has the coil baffle plate, not only strengthened the rigidity of skeleton, prevent that foreign object strike from producing distortion, and can be against on the coil baffle plate of skeleton around the upper and lower side of the coil of skeleton periphery, can prevent that loosening phenomenon from appearring in coil, and the coil baffle plate of skeleton is between coil and clamping plate, make coil and clamping plate to separate, avoided the phenomenon of coil discharge during use, insulation effect is good, again owing to the coil baffle plate on the short side relative on the skeleton is the broach shape, not only be convenient to the terminals outlet of coil, and can play the effect of heat radiation, the utility model reliability height, coefficient of safety height, and long service life.
