Abstract
The invention discloses a directly-welded wound stator of a direct current brushless motor, and relates to a wound stator of a motor. In an ordinary wound stator of the direct current brushless motor, after the winding or embedding of enameled wires is finished, the enameled wires are welded with flexible conductors and then led out, and after the welding, the enameled wires and the flexible conductors are required to be wrapped in an insulating way and outgoing lines of the leading-out flexible conductors are required to be bound, so efficiency is low; and the led-out conductors of the wound stator are required to be connected with a controller. The directly-welded wound stator is characterized in that: the end face of a left insulating bushing is provided with conducting strips which are electrically connected with corresponding windings; and the conducting strips are welded with a control circuit board, and are plastically packaged into a whole with the left insulating bushing in an injection molding way as inserts. The conducting strips are directly plastically packaged on the bushing, wound enameled wires are directly wound on the conducting strips, and then the conducting strips are directly welded to the control circuit board, so a welding link is reduced and assembly efficiency is improved; and the conducting strips are directly welded with the control circuit board, so the product has high reliability and a small volume.
Description
Technical field
The present invention relates to a motor lines stator.
Background technology
Traditional general dc brushless motor line stator all is to adopt the line stator to draw after welding with flexible conductor behind intact line or the intact line of embedding at enamelled wire, and the lead after drawing is connected with controller again.Two pads are arranged from the line stator to controller, and enamelled wire and the welding of flexible conductor also have being connected of flexible conductor and controller line plate.See from version and mainly to have following defective:
1, enamelled wire and draw between the flexible conductor welding and welding after will the insulate outlet colligation of wrapping and lead-out wire, the operating time is long, efficient is lower.
2, need once be connected again between line stator lead-out wire and the controller, increase unreliable factor.
Summary of the invention
The technical problem that the present invention will solve and the technical assignment of proposition are that the prior art scheme is improved and improved, and a kind of directly welded dc brushless motor line stator are provided, to reach easy to connect, the high purpose of reliability.For this reason, the present invention takes following technical scheme.
A kind of directly welded dc brushless motor line stator; Comprise stator core, winding, be coated at the left and right insulating bushing of stator core; It is characterized in that: described left insulating bushing end face is provided with corresponding winding electric and connects conducting strip; Described conducting strip and control circuit board welding, described conducting strip is integral through injection moulding and left insulating bushing plastic packaging as inserts.On lining directly plastic packaging conducting strip; The winding enamelled wire can adopt QA directly welded enamelled wire, will be directly on conducting strip around the enamelled wire behind the intact line, and conducting strip is soldered directly on the control circuit board more then; Reduce the welding link; Improve efficiency of assembling, and conducting strip is direct and the control circuit board welding, good reliability.Motor lines stator and control circuit board are integrated, and volume greatly reduces, and product reliability is good.
As the further of technique scheme improved and replenish, the present invention also comprises following additional technical feature.
The head of conducting strip is the lining connecting portion that is embedded in the left insulating bushing, and the afterbody of conducting strip is the control circuit board connecting portion that is connected with control circuit board, and described lining connecting portion is provided with the blend stop of symmetry.The setting of blend stop avoids conducting strip from insulating bushing, to extract.
After the blend stop of conducting strip lining connecting portion is oblique formation is set and pulls out thorn.Improve the connection reliability of conducting strip and insulating bushing.
The width of the lining connecting portion of conducting strip is greater than the width of control circuit board connecting portion.
The control circuit board connecting portion is " worker " font.Be convenient to welding.
The middle part of conducting strip is the winding connecting portion, and described winding connecting portion is established the lead positive stop strip of symmetry, the oblique setting of described positive stop strip, big outer little winding link slot in forming.In big outer little winding link slot can avoid winding when inserting control circuit board, to damage and the disengaging of winding connecting line.
Overhanging end and control circuit board welding behind the control circuit board connecting portion insertion control circuit board of conducting strip.
Described conducting strip is zinc-plated copper sheet.
Be provided with spacer between described stator core end face and the right insulating bushing inner face; Described spacer has the iron core slot identical with stator core; The inner ring of spacer is provided with a plurality of Location resilient pieces that extend internally, and the inner face of a plurality of Location resilient pieces forms the centring ring concentric with stator core.Location resilient piece tool elasticity, convenient for assembly, reduce the thrust when assembling, avoid the deformed damaged of stator, the centring ring of spacer is concentric with stator core, and the realization stator core is reliably located.Location resilient piece and fixing bracket body interference fit are in motor operation course, because of Location resilient piece has elasticity; Can keep being connected with fixing bracket body all the time; Avoid producing and rock, on the other hand, the effect assurance stator that spacer had just played reverse thrust after stator was seated is in axial position.
Beneficial effect: will be directly on conducting strip around the enamelled wire behind the intact line, conducting strip is soldered directly on the control circuit board more then, reduces the welding link, improves efficiency of assembling, and conducting strip directly welds good reliability with control circuit board.Motor lines stator and control circuit board are integrated, and volume greatly reduces, and product reliability is good.
