Description
Technical field
The utility model relates to compressor apparatus technical fields, can be improved punching utilization rate and guarantor more particularly, to one kind
Demonstrate,prove the stator module of Joint Reliability.
Background technique
Compressor is a kind of driven fluid machinery that low-pressure gas is promoted to high pressure gas, is the heart of refrigeration system.
It is operated after compressing with piston to it, to exhaust from the refrigerant gas of air intake duct sucking low-temp low-pressure by motor
The refrigerant gas of high temperature and pressure is discharged in pipe, provides power for refrigeration cycle.
Common compressor includes a motor unit, and motor unit has a stator and a rotor, rotor
It is rotatably installed near stator, further includes a crankshaft, a connecting rod and a piston.Coil is wound on stator, it is fixed
The magnetic line of force is generated between son and rotor, in the case where energization, magnetic flux, which changes, rotates rotor.
However, existing stator module, because lead-out wire lacks protection, it is low poor with Joint Reliability that there are punching utilization rates
The problem of.
Therefore, a kind of stator module that can be improved punching utilization rate and guarantee Joint Reliability is designed, is just seemed very
It is necessary.
Utility model content
The utility model is to overcome in the prior art, and existing stator module is low there are punching utilization rate and connector can
By the problem of property difference, a kind of stator module that can be improved punching utilization rate and guarantee Joint Reliability is provided.
To achieve the above object, the utility model uses following technical scheme:
A kind of stator module, including stator, the coil on stator and the coil lead on coil；The stator
If being laminated by dry plate motor stamping, each motor stamping in a ring, is equipped with several on the inner ring of each motor stamping
Groove, the coil lead are fixedly connected with coil, and coil lead end is equipped with connector.
In the utility model, motor stamping calculates flux density according to forehead, designs forehead width, determines outer shape size,
Punching utilization rate is improved, the forehead width is the distance between motor stamping upper groove bottom end and motor stamping edge.In addition,
Coil lead, using the connection type for adding soldering again is first crimped, increases the reliability of coil lead end fitting with coil.This
Utility model has the characteristics that can be improved punching utilization rate and guarantees Joint Reliability.
Preferably, the groove on each motor stamping is in U-shape, bottom portion of groove is arc, and the width of bottom portion of groove is big
In the width of slot opening.
Preferably, the distance between each groove bottom end and the edge of motor stamping are 18mm-20mm.
Preferably, the institute on each motor stamping inner ring is fluted along the distribution of motor stamping inner ring even circumferential, it is each
The opening of groove is equipped with symmetrical stopper.The stopper being equipped at each slot opening can be to the line being located on groove
Circle, plays better position-limiting action.
Preferably, being successively arranged polyester casing and membrane casing outside coil lead.Polyester set is used outside coil lead
Pipe plus membrane casing, duplicate protection coil lead are not worn, it is ensured that the security performance of stator module.
Preferably, connector exterior is equipped with heat-shrinkable T bush.Coil lead uses the connection for first crimping and adding soldering again with coil
Mode, connector external application heat-shrinkable T bush shrink protection, can effectively ensure that the reliability of connector.
Preferably, coil is located in the groove on stator.
Therefore, the utility model has the following beneficial effects: (1) motor stamping calculates flux density according to forehead, forehead is designed
Width determines outer shape size, improves punching utilization rate；(2) polyester casing is used to add membrane casing outside coil lead, it is dual
Coil lead is protected not wear, it is ensured that the security performance of stator module；(3) coil lead uses first to crimp with coil adds soldering again
Connection type, connector external application heat-shrinkable T bush shrink protection, can effectively ensure that the reliability of connector.
Detailed description of the invention
Fig. 1 is a kind of structure top view of the utility model；
Fig. 2 is a kind of structure sectional view of the utility model；
Fig. 3 is a kind of structural schematic diagram of the motor stamping in the utility model.
In figure: stator 1, coil 2, coil lead 3, motor stamping 4, groove 5, connector 6, stopper 7.
Specific embodiment
The utility model is further described with specific embodiment with reference to the accompanying drawing:
Embodiment: stator module as shown in Figure 1 to Figure 3, including stator 1 and are set to coil at coil 2 on stator
On coil lead 3；If the stator is laminated by dry plate motor stamping 4, each motor stamping in a ring, each motor
Several grooves 5 are equipped on the inner ring of punching, the coil lead is fixedly connected with coil, and coil lead end is equipped with connector
6。
Wherein, as shown in figure 3, the groove on each motor stamping is in U-shape, bottom portion of groove is arc, bottom portion of groove
Width is greater than the width of slot opening.Institute on each motor stamping inner ring is fluted along motor stamping inner ring even circumferential point
Cloth, the opening of each groove are equipped with symmetrical stopper 7.The stopper being equipped at each slot opening can be recessed to being located at
Coil on slot plays better position-limiting action.Four top corner edges of each motor stamping are stepped.Each vertex
It is equipped with fixation hole.The left and right sides edge of each apex angle is equipped with the notch of " W " shape.
In addition, being successively arranged polyester casing and membrane casing outside coil lead.Polyester casing is used to add outside coil lead
Membrane casing, duplicate protection coil lead are not worn, it is ensured that the security performance of stator module.Connector exterior is equipped with heat-shrinkable T bush.
Coil lead shrinks protection using the connection type for adding soldering again, connector external application heat-shrinkable T bush is first crimped with coil, can be effective
Guarantee the reliability of connector.
In addition, coil is located in the groove on stator.
