Description
Technical field
The utility model relates to a kind of wiring ejector of hollow-cup motor winding leading-out wire.
Background technology
The winding leading-out wire of existing hollow-cup motor is drawn with one piece of single-sided circuit board, and this structure has several defect:
1, lead-out wire is directly welded on the pad of circuit board plane, and cause lead-out wire to bear and larger pull power, the stress of pad is very concentrated in addition, if the lead-out wire of motor is often torn or motor is in the large environment of vibrations and very easily ruptures;
2, this circuit board is single sided board, and plate face area is very little, causes the very little not easy heat radiation of copper disc area that plate face is arranged, welding improper is be easy to cause copper bar to come off; Because the little pad of board area is too tight, the arrangement of pad cannot be accomplished completely rationally, and motor winding is needing longer cross-line with during welding circuit board, and winding the end of a thread needs to add extra insulating sleeve otherwise understands short circuit, and this sleeve pipe often can wipe iron core because of it; Original structure board pads is little, and is close to winding, causes the status requirement at winding the end of a thread coating removal position very high, more difficult operation;
3, the copper bar on circuit board is very thin, and the flow conductivity difference of copper bar can not bear larger electric current, and this can the range of application of serious limiting motor, and also easily to cause that the motor feels hot poor with overload capacity simultaneously;
4, outside circuit board be exactly the casing of metal, because space is little, the pad on circuit board and copper bar, distance metal chassis is very near, and creepage distance is short, is easy to cause motor withstand voltage bad after welding, and bears withstand voltage ability, and fail safe is bad;
5, process operability is poor, scrappage is higher, and because hollow-cup motor diameter is less, inner space is little, existing structure be first circuit board is adhered to iron core end face after carry out bonding wire again, operate cumbersome, and have the scrappage of about 5%.
Summary of the invention
In order to solve the problem, the utility model provides a kind of wiring ejector of hollow-cup motor winding leading-out wire, simple and reasonable, reduce the stress of winding leading-out wire welding position, increase copper bar current capacity, and raising electrical machine insulation ability that can be very large, fitting operation is simple, add the reliability of motor, fail safe, improve the manufacturability of motor.
For achieving the above object, concrete scheme of the present utility model is:
A kind of wiring ejector of hollow-cup motor winding leading-out wire, comprise double face annular wiring board, be buckled in the annular insulating end cap of wiring board, three Hall part fixed fields are circumferentially evenly equipped with in the side plate face of wiring board, three place's copper bars are provided with in another lateral plates of wiring board, wiring board is provided with the plate face of copper bar towards insulated end cover, wiring board is provided with the plate face of Hall part fixed field back to insulated end cover, three notches are evenly equipped with in the cylindrical circumferential edge of wiring board, three cable-through holes are provided with at the edge of wiring board, three location notchs are evenly equipped with in the inner circle circumferential edge of wiring board, a circle flange is provided with at the cylindrical of insulated end cover, end face along flange is evenly equipped with three teeth, three teeth of flange are embedded in three wiring board notches respectively, one end of three lead-out wires of motor winding is fixedly welded on three place's copper bars of wiring board respectively, the other end 90 ° of three lead-out wires of motor winding is bending to be passed along three cable-through holes of circuit plate respectively, three winding the end of a thread of motor winding are embedded in three wiring board location notchs respectively.
The utility model beneficial effect:
1, adopt double sided board to increase wiring board area, arrangement large area copper bar, increases copper bar current capacity;
2, secondly lead-out wire has welded rear 90 ° of cable-through holes bent through on circuit board, reduces the stress of welding position;
3, insulating end plate is designed, for the protection of welding position and the storage lead-out wire of projection, and raising electrical machine insulation ability that can be very large;
4, this circuit board for receiving lead-out wire reinstalls casing after can directly welding, and simple to operate, does not substantially have scrappage;
5, solder pad arrangements is reasonable, and motor winding is saving time with during welding circuit board, and winding the end of a thread, without the need to adding extra insulating sleeve, can well avoid iron core by the problem of wiping;
6, circuit board has the location notch of winding the end of a thread, and pad locations is reasonable, makes the position relationship of the phase place of the winding of motor and lead-out wire thereof more stable, make the position of Hall more accurate in conjunction with 2;
7, bonding pad area large and and isolated by insulating end plate between winding, the status requirement at winding the end of a thread coating removal position is reduced, easily operates;
8, not only increase the reliability of motor, fail safe, also improve the manufacturability of motor.
