Sleeve 2, preceding conducting ring 3, rear conducting ring 4, forward and backward conducting ring hot jacket is on sleeve 2, and entire collector ring hot jacket is on motor shaft 1；
As shown in Fig. 2, 10 one end of preceding conducting bolt screws in preceding conducting ring 3, the other end is connected with corresponding copper bar 11, in energization situation
Under, it is contacted by the threaded engagement between preceding conducting bolt and preceding conducting ring, plays current lead-through；It is led after as shown in figure 3,
Conducting ring 4 after 12 one end of electric bolt passes through preceding conducting ring 3 and screws in, the other end is connected with corresponding copper bar 11, in energization situation
Under, it is contacted by the threaded engagement between rear conducting bolt and rear conducting ring, plays current lead-through.
The main problem existing for structure that is connected and fixed of existing copper bar and conducting ring is：Between conducting ring and conducting bolt
Conduction is carried out by threaded engagement, and cooperation causes to lead there are gap between the internal thread of conducting ring and conducting bolt external screw thread
Contact that effect is bad, and conducting bolt current density is higher between electric bolt and conducting ring, when galvanization easily causes conducting ring mistake
Heat makes 13 insulation performance of insulating sleeve be deteriorated, and stick in so as to cause 13 aging of insulating sleeve being socketed on conducting wire bolt
On conducting bolt, the service life of collector ring is seriously affected, and existing connection structure is complex, and assembly process is more,
Assembly is welded with conducting ring mostly, can not simply complete independent disassembling, and repair dismounting is inconvenient.
