By using above-mentioned technical proposal, between binding post and insulation sleeve die casting fix, realize between the two firm
Connection, the conduction and insulating properties of junction block are more reliable.
Further, second hold-down bolt is fixedly connected with insulating cord close to one end of the first hold-down bolt；
First hold-down bolt coaxially offers the threading hole passed through for insulating cord, and the insulating cord passes through threading hole simultaneously
The fastening bolt being threadedly attached on insulation sleeve is fixed.
By using above-mentioned technical proposal, the cable being electrically connected with coil and brush holder is compressed and is contradicted by the second hold-down bolt
On binding post, then insulating cord is passed through to the threading hole of the first hold-down bolt, it will be in the first hold-down bolt precession through-hole and with the
One thread segment is threadedly coupled；Finally insulating cord is tensed and is threadedly attached in the fastening bolt on insulation sleeve and is fixed, is realized
To the tensioning function of the second hold-down bolt, the generation of the second hold-down bolt loose phenomenon is reduced, to improving the second compression
Stability of the bolt to cable pressuring action.
In conclusion the utility model has the advantages that：
1. insulation division and wire connecting portion are used, to generate the effect for facilitating motor wiring；
2. bulge loop is used, to generate the stable connection for improving binding post and insulation sleeve；
3. using insulating cord, threading hole and fastening bolt, make to improve the second hold-down bolt and be compressed to cable
Stability.
