Inserted sheet described above and casing are that integrated punching is shaping.
Locking terminal described above comprises substrate and stretches out from substrate both sides and the tabs of bending, and between substrate and two tabs, form slot, inserted sheet stretches into and is locked at inside slot.
One end of ground wire described above arranges locking terminal, and the other end arranges wired ear.
Casing two ends described above all respectively circumference offer some ventilation holes, and the position of a ventilation hole is wherein provided with inserted sheet.
Inserted sheet described above stretches out from the inwall of ventilation hole and extends inside ventilation hole.
The direction that inserted sheet described above extends inside ventilation hole is circumference.
The utility model compared with prior art, has following effect:
1) casing offers some ventilation holes, the position of a ventilation hole is wherein provided with inserted sheet, inserted sheet is connected with casing, ground wire is electrically connected by locking terminal and inserted sheet, structure is simple, assembling is efficient, solves ground wire screw and motor coil winding overhang in the problem of casing internal creepage distance deficiency, adds space and the end height of the shaping of motor coil winding outer rim simultaneously;
2) inserted sheet and casing are that integrated punching is shaping, and production technology is simple, and cost is low, and structure is reliable;
3) locking terminal comprises substrate and stretches out from substrate both sides and the tabs of bending, and between substrate and two tabs, form slot, inserted sheet stretches into and is locked at inside slot, and structure is simple, connects reliable;
4) inserted sheet stretches out from the inwall of ventilation hole and extends inside ventilation hole, and the direction that inserted sheet extends inside ventilation hole is circumference, and structure is simple, effectively utilizes the position inside ventilation hole, makes the connection between inserted sheet and locking terminal convenient.
