Abstract
The invention discloses a connecting structure of an terminal shell of a motor stator. The terminal shell comprises a top cover and a soleplate; three slots are formed between the top cover and the soleplate; the bottom surfaces inside the slots respectively form three inclined bosses upwards; the inclined bosses and the soleplate form an inclined slope; the terminal shell is formed by injection moulding integrally. The connecting structure of the invention changes the vertical boss of the slot to the inclined boss, thus avoiding the misalignment appearing during the processing of the end; simultaneously, the connecting structure always ensures the normal connection of the end and the terminal shell, reduces the connection difficulty of the end and the terminal shell, leads the connection of the end and the terminal shell to be firmer, reduces the rework rate and improves the working efficiency.
Description
Technical field
The invention belongs to a kind of motor stator structure, be specifically related to a kind of syndeton of terminal shell of 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.
The household electrical appliance that power is slightly little like window air conditioner, wall-hanging air conditioner etc., adopt monophase machine mostly.Be not with the enamelled wire winding on the monophase machine rotor, the electric current in the rotor is not supplied with by external power, but induce by stator field.Induced current and former magnetic field interaction make rotor rotation.
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 is provided with the terminal shell 1 that is connected with power line above motor stator 3, connected by lead 5 between the stator winding in terminal shell 1 and the motor stator 3.Terminal shell 1 comprises top cover 6 and base plate 7, forms three slots 8 between top cover 6 and the base plate 7, the end face three slots 8 in form respectively three semicircular protruding 10,10 pairs of lead-out wires of convexity have guide effect.Bottom surface in three slots 8 forms three boss 9 respectively, and boss 9 forms step with base plate 7.On top cover 6, form fairlead 12 respectively, form flange 11 respectively at the two ends of top cover 6.
But, the syndeton of the terminal shell of the motor stator of prior art, in the terminal shell connected operation, because the terminal bad order, the outstanding terminal of lead-out wire was long, made between terminal and the terminal shell often can't normally be connected, and portioned product need return line and process.And, cause waste in man-hour and fraction defective to rise owing to connect the normally connection of slot position that needs terminal aligned with terminal shell in the operation.
Summary of the invention
The present invention proposes in order to overcome shortcoming of the prior art, and purpose provides a kind of syndeton of terminal shell of motor stator.
Technical scheme of the present invention is: a kind of syndeton of terminal shell of motor stator, and the terminal shell is installed in the top of motor stator, is connected by lead between the stator winding in terminal shell and the motor stator; The terminal shell comprises top cover and base plate, forms three slots between top cover and the base plate, and wherein the centre is provided with a slot; Both sides respectively are provided with a slot; Bottom surface in three slots forms three inclined platforms respectively, and gradient is 1:3～5, and inclined platform and base plate form the slope.On top cover, form three fairleads respectively.
Terminal shell integrated injection molding.
The syndeton of the terminal shell of motor stator of the present invention changes the vertical boss in the slot into inclined platform; Thereby avoided terminal to add the deviation that occur man-hour; Simultaneously guaranteed that all the time terminal is connected with the normal of terminal shell, reduced terminal and the difficulty that the terminal shell is connected, made terminal more firm with being connected of terminal shell; Reduce rework rate, improved operating efficiency.

Embodiment
With embodiment the syndeton of the terminal shell of motor stator of the present invention is elaborated with reference to the accompanying drawings:
In the accompanying drawings, identical parts use identical label.
Shown in Fig. 4～6, the terminal shell 13 in the syndeton of the terminal shell of motor stator of the present invention is installed in the top of motor stator 3, is connected by lead 5 between the stator winding in terminal shell 13 and the motor stator 3.Terminal shell 13 comprises top cover 14 and base plate 15; Form three slots between top cover 14 and the base plate 15; Be provided with a slot 18 wherein, both sides respectively are provided with a slot 17, and it is along the electrical axis direction; Middle slot 18 is lower than two side slots 17, low in the middle of promptly being, that both sides are high " recessed " font structure.Bottom surface in each slot in three slots 17,18 upwards respectively forms the inclined platform 16 that increases of the gradient from left to right, forms three inclined platforms altogether.The gradient of three inclined platforms 16 that bottom surface in slot 17,18 forms is about 1: 3～and 5, inclined platform 16 and base plate 15 formation slopes.On top cover 14, form three fairleads 20 respectively.
The syndeton of the terminal shell of motor stator of the present invention changes the vertical boss in the slot into inclined platform; Thereby avoided terminal to add the deviation that occur man-hour; Simultaneously guaranteed that all the time terminal is connected with the normal of terminal shell, reduced terminal and the difficulty that the terminal shell is connected, made terminal more firm with being connected of terminal shell; Reduce rework rate, improved operating efficiency.
