Abstract
The utility model discloses a kind of conducting ring electricity ejector of motor, solve on the one hand that existing electric motor winding end is compact, the narrow and small difficult problem causing wiring difficulty of wiring space.Solve on the other hand contact resistance that conducting ring and lead-out wire contact area cause not greatly, the problem such as serious of generating heat.The utility model, when ensureing that conducting ring insulation property are constant, increases the contact area of conducting ring and lead-out wire, reduces heating, ensures its electric property.
Description
Technical field
The utility model relates to a kind of conducting ring electricity ejector, particularly the conducting ring electricity ejector of motor.
Background technology
For the motor that winding overhang is compact, when connecting conducting ring, there will be following problem: (1) conducting ring and lead-out wire contact area deficiency cause loose contact; (2) insulating material wrapped is damaged when welding conducting ring and lead-out wire; (3) insufficient space causes connecting conducting ring and lead-out wire difficulty.
Utility model content
The utility model provides a kind of conducting ring electricity ejector of motor, solve on the one hand that existing electric motor winding end is compact, the narrow and small difficult problem causing wiring difficulty of wiring space, solve on the other hand contact resistance that conducting ring and lead-out wire contact area cause not greatly, the problem such as serious of generating heat.
The utility model is overcome the above problems by following scheme:
Conducting ring electricity ejector comprises insulating barrier and the tin solder being connected conducting ring and lead-out wire of conducting ring, lead-out wire, coated with conductive ring, insulating barrier comprises the polyimide film glass low resin mica tape half-stack package three layers of conducting ring and lead-out wire junction, alkali-free glass fibre band half-stack package is two-layer, the polyimide film glass low resin mica tape half-stack package four layers of the coated with conductive ring outside junction, alkali-free glass fibre band half-stack package one deck.
The contact-making surface of conducting ring and lead-out wire junction is warded off full by tin solder.
Conducting ring is fixed on the stator support of wound stator core end, is fixed by screw and packing ring by pressing plate.
The utility model is when winding overhang insufficient space, adopt the structure of bolted+tin welding, avoid the problem easily loosened when different metal threaded connection is cold and hot to be changed, save attaching nut and improve operability when insufficient space, ensure electrical connection contact area simultaneously, solve conducting ring and lead-out wire connectivity problem well.
The utility model utilizes Medium frequency induction welding machine, welds with lead-out wire junction conducting ring.Tin solder fusing point is low, and Medium frequency induction welding machine firing rate is fast, can ensure that the insulating material on conducting ring is injury-free; Adopt bolt to carry out fastening, side weld edge fit is fastening simultaneously.
The utility model, when ensureing that conducting ring insulation property are constant, increases the contact area of conducting ring and lead-out wire, reduces heating, ensures its electric property.
Accompanying drawing explanation
Fig. 1 is winding overhang structural representation of the present utility model;
Fig. 2 is conducting ring of the present utility model and lead-out wire connection diagram.
Embodiment
Conducting ring electricity ejector comprises insulating barrier and the tin solder being connected conducting ring 3 and lead-out wire 5 of conducting ring 3, lead-out wire 5, coated with conductive ring 3, insulating barrier comprises the polyimide film glass low resin mica tape half-stack package three layers of conducting ring and lead-out wire junction, alkali-free glass fibre band half-stack package is two-layer, the sequence number 1 polyimide film glass low resin mica tape half-stack package four layers of the coated with conductive ring outside junction, sequence number 2 alkali-free glass fibre band half-stack package one deck.
Be fixed at sequence number 3 conducting ring and have wound stator core end and before being connected with sequence number 5 lead-out wire, sequence number 1 polyimide film glass low resin mica tape half-stack package four layers is used along conducting ring (removing and lead-out wire junction), sequence number 2 alkali-free glass fibre band half-stack package one deck, ensures its insulation property.Secondly the three-phase conducting ring after wrapping is fixed on sequence number 8 stator support of winding overhang successively, sequence number 9 pressing plate is installed, is fixed with sequence number 10 screw and sequence number 11 packing ring, makes conducting ring be fixed on winding overhang.Again, its contact-making surface full is warded off at conducting ring and lead-out wire junction sequence number 4 tin solder, sequence number 6 bolt is adopted to be connected fastening conducting ring and lead-out wire with sequence number 7 packing ring, weld conducting ring and lead-out wire simultaneously, side weld connects heating edge and tin solder is incorporated space, unnecessary tin solder is extruded by fastening bolt simultaneously, thus ensure that contact area.
The connection of conducting ring and lead-out wire adopts on the one hand welds fastening, and another aspect adopts bolted.Medium frequency induction welding machine is adopted during welding, tin solder is adopted to weld, ensure that welding temperature is in 220 DEG C (tin solder fusing point) left and right, can ensure on the one hand not damage the sequence number 1 polyimide film glass low resin mica tape and sequence number 2 alkali-free glass fibre band wrapped, ensure on the other hand to be heated evenly.At conducting ring and lead-out wire junction polyimide film glass low resin mica tape half-stack package three layers after welding, alkali-free glass fibre band half-stack package is two-layer, brush quick-drying paint.Now, both ensured the insulation property of conducting ring, ensured again that the insulating material that conducting ring has been wrapped was injury-free.This method of attachment increases the contact area of conducting ring and lead-out wire, reduces heating, ensures the electric property of motor.
The utility model adopts Medium frequency induction welding machine, ensures to be heated evenly; Adopt tin solder, ensure that the insulating barrier wrapped is injury-free; Before welding scolding tin material is warded off the contact-making surface of full conducting ring and lead-out wire, side weld edge fit is fastening, ensures that the contact area of conducting ring and lead-out wire is enough large.The utility model connects conducting ring and lead-out wire well when winding overhang insufficient space.
