Abstract
The invention discloses a connection structure of an overload protection terminal casing for a motor stator. The connection structure comprises a terminal casing arranged above the motor stator and connected with the stator windings inside the motor stator via conducting wires, three wire holes respectively formed on the top cover of the terminal casing, metal connectors arranged on the lateral surfaces of the terminal casing, and an overload protector arranged between the top cover at one end of the terminal casing and the bottom plate of the terminal casing. The terminal casing comprises the top cover, the bottom plate and three insert slots formed between the top cover and the bottom plate, and a tilted boss formed on the bottom plate inside the insert slot on the right side. The tilted boss and the bottom plate form an inclined slope, so as to avoid the deviation during the process of manufacturing the terminal, ensure the firmer connection between the terminal and the terminal casing without falling off, reduce the rework rate and improve the work efficiency and reliability.
Description
Technical field
The invention belongs to a kind of motor stator structure, be specifically related to a kind of in the terminal shell lead connect the syndeton of the overload protection terminal shell of firm motor stator.
Background technology
Compressor is the important composition parts that air conditioner, refrigerator etc. utilize the household electrical appliance of cooling cycle system work.The moving piston of compressor (rolling piston or reciprocating piston) changes mechanical energy into the pressure ability under the drive of motor, realize the compression to the compresser cylinder inner refrigerant.The rotation of motor through corresponding component under the current field effect convert electrical energy into rotary machine can, for the running of compressor provides power.Therefore, motor is the vitals of compressor, and its behavior in service directly influences the function performance of compressor.
In general, motor is made up of stator and rotor two parts, and stator and rotor are made up of the iron core that the folded collection of silicon steel sheet forms respectively.Single stator lamination is circular, and the stator core that is made up of the folded collection of lamination is cylindric.Rotor is cylindric, and rotor directly is pressed on the bent axle and inserts in the cylinder cavity of stator core, has air-gap to be separated by between rotor and the stator.Embed the winding of enamelled wire coiled on the stator, stator winding produces magnetic field when source current passes through outside.Rotor interacts with stator field when having electric current to pass through, and the generation electromagnetic torque also rotates in stator.
For the bigger air conditioner of capacity, the necessary bigger compressor electric motor of adapted capacity, compressor electric motor power is generally about 1.5 kilowatts.The overload protection terminal shell that also must have overload protection function for the terminal shell of the bigger compressor electric motor institute adapted of capacity.
Shown in Fig. 1～3; Insulating frame 4 under the connection below the motor stator 3 of prior art; Insulating frame 2 in the connection on motor stator 3; Above motor stator 3, be provided with the overload protection terminal shell 1 that is connected with power line, connect by lead 5 between the stator winding in overload protection terminal shell 1 and the motor stator 3.
Overload protection terminal shell 1 comprises top cover 6 and base plate 7, forms three slots 10 between top cover 6 and the base plate 7, and the slot on the left side connects the main coil of motor, and middle slot connects the secondary coil of motor, and the slot on the right is a common port.Bottom surface in three slots 10 form respectively three semicircular protruding 11, protruding 11 pairs of lead-out wires have guide effect.On top cover 6, form three fairleads 8 respectively, be provided with metal connecting sheet 9 in the side of terminal shell 1, between the top cover 6 of an end of terminal shell 1 and base plate 7, be provided with overload protective device 13, slot inner bottom plating 7 on the right forms perpendicular steps 12 with protruding 11.
But the syndeton of the overload protection terminal shell of the motor stator of prior art connects in the operation at the terminal shell, because public terminal connection power is not tight, causes terminal to come off, and has to carry out operation again, and production efficiency is descended.And, in case coming off, terminal just might flow into the next stage assembling, get into compressor inside and cause burn-down of electric motor.
Summary of the invention
The present invention proposes in order to overcome shortcoming of the prior art, purpose provide a kind of in the terminal shell lead connect the syndeton of the overload protection terminal shell of firm motor stator.
Technical scheme of the present invention is: a kind of syndeton of overload protection terminal shell of motor stator; Comprise that the terminal shell is installed in the top of motor stator; Connect by lead between the stator winding in terminal shell and the motor stator; On top cover, form three fairleads respectively, be provided with metal connecting sheet, between the top cover of an end of terminal shell and base plate, be provided with overload protective device in the side of terminal shell.
The terminal shell comprises top cover and base plate, forms three slots between top cover and the base plate, and slot inner bottom plating on the right forms inclined platform.The gradient of inclined platform is about 1:3～5, and inclined platform and base plate form the slope.Top cover in the terminal shell, base plate, fairlead, slot, convexity and inclined platform integrated injection molding.
The syndeton of the overload protection terminal shell of motor stator of the present invention changes the vertical boss in the common port slot on the right into inclined platform; Thereby avoided terminal to add the deviation that occur man-hour; All the time guaranteed simultaneously firm more, the difficult drop-off of being connected of terminal with the terminal shell; Reduce rework rate, improved operating efficiency and reliability.
