Description
(1) technical field
The technical field that this patent is related to is：Threephase asynchronous, specially using the one of vacuum pressure impregnation technique
Plant scattered joint between embedding low-voltage three phase asynchronous motor lead wire and winding wire.
(2) background technology
With the continuous improvement of motor manufacturing technology, dissipating embedding low voltage motor has the wound stator key unshakable in one's determination as motor
Part, its impregnated insulating paint handling process is progressively immersed to vacuum pressure impregnation (abbreviation VPI dipping lacquers) transition from common, uses
VPI dipping lacquers have wound stator unshakable in one's determination, can improve the insulated paint inside wound stator iron core and be impregnated with degree, make machine winding
Globality is improved, and the thermal diffusivity of motor, NBC protective performance (protection against the tide, waterproof, mould proof) are improved.
VPI paint-dipping process, has wound stator iron core to vacuumize not yet dipping lacquer, makes work exactly in special equipment
Part internal air gap is in negative pressure state, then the insulated paint of dipping is injected in impregnating vessel, due to the effect of negative pressure, insulated paint meeting
Sufficiently entering has at each unshakable in one's determination solid gap of wound stator, releases after vacuum, then insulated paint is imposed it is certain just
Dipping lacquer is more abundant inside pressure, winding, including insulated paint is full of between the lead wire insulating barrier internal core on winding, finally
By special drying device to dipped insulated paint have wound stator iron core dry, insulated paint cure hard, entirely have around
Group stator core will become the solid entirety of an air-gap-free.
The negative interaction of VPI paint-dipping process is easily to make have the lead wire on wound stator iron core to be hardened, particularly lead wire
Larger (the generally higher than 50mm of sectional area2) in the case of it is more serious.Lead wire, which is hardened, influences the synthesis assembling of motor, motor dress
Timing, dipped insulated paint has wound stator iron core to be pressed into support, and lead wire needed through support line outlet in wire connection cavity
Wiring is carried out with the binding post on connecting plate, because wiring cavity space is limited, wiring position is not known, it is desirable to which lead wire should softness
It is easy to threading to install, particularly when lead wire sectional area is larger, it is desirable to higher, has winding to determine through what VPI paint-dipping process was handled
Sub- iron core lead wire is difficult the matching requirements for meeting motor.
Before VPI paint-dipping process occurs, dissipating embedding low pressure has wound stator most common dipping lacquer mode unshakable in one's determination to immerse, specifically
Way is：There is the wound stator preheating unshakable in one's determination Jing Guo certain time certain temperature, be immersed into one in the insulated paint under normal pressure
Fix time, then by drop paint drying, complete the insulation processing for having wound stator unshakable in one's determination.There is winding to determine during due to dipping lacquer at ambient pressure
Sub unshakable in one's determination internal space can not all be discharged, therefore have wound stator impregnability unshakable in one's determination typically using immerse mode dipping lacquer,
Motor globality can be influenceed by certain, and lead wire is during dipping lacquer due to the effect without negative pressure and malleation, lead wire
Internal general not to have insulated paint entrance, or the insulated paint entered is seldom, the lead wire situation that is hardened is not protruded, when motor is assembled not
It can be affected.
(3) content of the invention
Lead wire is that motor has a wound stator part unshakable in one's determination, is one section of single-core cable being connected with winding end line,
This cable is made up of the zinc-plated copper wire of multiply and outer layer insulation, and zinc-plated copper wire is general compared with thin and quantity is more, and outer layer insulation is general
It is made up of the soft class heat resistant rubber such as silicon rubber, therefore motor lead is soft before winding dipping lacquer.
The tie point of winding end and lead wire termination is exactly motor leading and connecting wire terminal, and general every motor has 3 or 6
Root lead wire, just has at 3 or joint at 6, the general requirement of joint is firm and reliable connection, and resistance is low, PROCESS FOR TREATMENT accordingly
Simply.
Conventional lead wire joint technique typically has two kinds：The first is welding, mainly there is solder brazing or melting welding, is embodied
Method is：Cable socket is removed into the core that insulating barrier exposes certain length first, winding termination removes enamel-covered wire coat of paint, will gone
Winding termination and the lead wire core for falling insulated part are hinged, butt end of having one's hair trimmed, by solder brazing or melting welding by termination
Weld, then insulating sleeve carries out insulation processing on welding position bag insulating tape set；Second is crimping, mainly passes through a company
Winding termination is crimped together by adapter with lead wire core two parts, then the insulating sleeve on crimping position bag insulating tape set.
Using conventional lead wire joint processing technique, either welding is still crimped with connecting tube, and stator winding is carried out
During VPI dipping lacquers, insulated paint can all enter lead wire core internal voids at winding joint, and by baking and curing, lead wire becomes
Obtain stone, it is not flexible, difficulty is brought to motor assembling, VPI paint-dipping process is promoted and encounters resistance.
By analysis, the reason for lead wire is hardened, it is very big with lead wire joint relation, whether weld or use connecting tube
Crimping mode, joint is all that an insulated paint leads to inside lead wire core to enter to paint passage, is soaked when there is wound stator iron core
When not in insulated paint, it is exposed at outside insulated paint, enters from lead wire free end because lead wire free end is generally erected state
It is impossible to enter insulated paint, therefore joint just enters to paint passage into unique one, blocks this passage, also just solves
The problem of cable is hardened.
The present invention is a kind of motor leading and connecting wire terminal, and the adapter body is a copper pipe, and copper pipe middle part is blocked provided with one,
During implementation, joint two ends are inserted into lead wire termination and winding end respectively, then wire barrel two ends are crimped through hydraulic tongs pressing mold,
The joint can realize that winding terminal and lead wire end are obstructed in copper pipe, and lead wire insulation outside inside lead wire core with connecing
Obstructed at head, when having wound stator iron core progress VPI dipping lacquers, the joint can block insulated paint to enter lead wire line by joint
Core inner, it is to avoid lead wire cable is hardened because of dipping lacquer.
