fixed iron core 1, fixed iron core 1 can set up in the compressor, makes coil structure can be applied to in the compressor, fixed iron core 1 can with the size that the compressor inner space corresponds, thereby makes fixed iron core 1 can arrange in the inner space of compressor. The fixed iron core 1 may be rectangular parallelepiped, or a rectangular parallelepiped fixed iron core 1

And the coil unit 2 can be wound on the fixed iron core 1, so that the coil unit 2 is fixed on the fixed iron core 1. In the present embodiment, the coil unit 2 is a three-phase coil, so that the coil unit 2 can be more adapted to the function of the compressor. Of course, in other alternative embodiments, the type of the coil unit 2 may be adjusted according to actual needs. The two ends of the coil unit 2 can be provided with a wire inlet end 21 and a wire outlet end 22 which are abutted against the wire outlet end 3 of the compressor, and both the wire inlet end 21 and the wire outlet end 22 are abutted against the wire outlet end 3 in the compressor, so that the wire inlet end 21 and the wire outlet end 22 can be located in the same area with the wire outlet end 3 in the compressor, a space unit in the compressor can be saved, and the condition of space waste caused by separation of the coil unit 2 and the wire outlet end 3 is avoided.

The insulating sleeve 4 can be sleeved on the wire inlet end 21 and the wire outlet end 22. In this embodiment, the wire inlet end 21 and the wire outlet end 22 extend along a straight line, so that the insulating sleeve 4 sleeved on the wire inlet end 21 and the wire outlet end 22 can be sleeved along the extending direction of the wire inlet end 21 and the wire outlet end 22, and the range of the insulating sleeve 4 can be enlarged. Of course, in other alternative embodiments, the extending directions of the wire inlet end 21 and the wire outlet end 22 may be adjusted according to actual needs, so that the extending direction of the insulating sleeve 4 is adjusted accordingly.

In this embodiment, after the coil structure is placed in the compressor, the compressor is turned on and off, when the compressor vibrates, the wire inlet end 21 and the wire outlet end 22 are displaced relative to the wire outlet end 3 to generate friction, and since the insulating sleeve 4 is sleeved on the wire inlet end 21 and the wire outlet end 22, the insulating sleeve 4 is arranged between the wire inlet end 21 and the wire outlet end 3 and between the wire outlet end 22 and the wire outlet end 3 to insulate the wire inlet end 21 and the wire outlet end 3. Even when the insulation protection paint of the wire inlet end 21 and the wire outlet end 22 falls off due to friction, the insulation sleeve 4 sleeved on the wire inlet end 21 can still protect the wire inlet end 21 from contacting the wire outlet end 3, and correspondingly, the insulation sleeve 4 sleeved on the wire outlet end 22 can also protect the wire outlet end 22 from contacting the wire outlet end 3, thereby generating a protection effect on the wire inlet end 21 and the wire outlet end 22.

The PU or plastic material has better insulating property and lower cost, so that the cost of the insulating sleeve 4 using the PU or plastic is lower and the insulating sleeve can be prepared on a large scale, and the cost of the coil structure can be reduced on the premise of ensuring that the coil structure in the compression is not conducted with the outlet end 3 by mistake.

Specifically, the insulating sleeve 4 may be fitted over the outlet terminal 3 abutting against the inlet terminal 21 and the outlet terminal 22 of the coil unit 2. The insulation sleeve 4 can insulate the outside of the outlet end 3 of the compressor, and on the premise that the inlet end 21 and the outlet end 22 are sleeved with the insulation sleeve 4, the insulation sleeve 4 is also sleeved outside the outlet end 3 which is in contact with the insulation sleeve 4 outside the inlet end 21 and the outlet end 22, namely, the insulation sleeve 4 on the inlet end 21 and the outlet end 22 is abutted against the insulation sleeve 4 on the outlet end 3, so that the insulation between the coil unit 2 and the outlet end 3 is further ensured.

Specifically, the line inlet end 21 may extend along the direction of the long side of the fixed iron core 1, so that the line inlet end 21 may extend along the linear direction, and extend along the direction of the long side of the fixed iron core 1, so that the line inlet end 21 may be extended as long as possible, and the range of the insulating sleeve 4 for sleeving the line inlet end 21 may be increased. The insulating sleeve 4 sleeved on the line inlet end 21 can extend to the bending region of the line inlet end 21, so that the insulating sleeve 4 sleeved on the line inlet end 21 can not block other winding regions, thereby avoiding the influence of the insulating sleeve 4 on the winding of the coil unit 2.

Specifically, the outlet end 22 may extend along the direction of the long side of the fixed core 1, so that the outlet end 22 may extend along a straight line direction, and extend along the direction of the long side of the fixed core 1, so that the outlet end 22 may be extended as long as possible, and the range of the insulating sleeve 4 for sleeving the outlet end 22 may be increased. The insulating sleeve 4 sleeved on the outlet end 22 extends to the bending area of the outlet end 22, so that the insulating sleeve 4 sleeved on the outlet end 22 can not block other winding areas, and the influence of the insulating sleeve 4 on the winding of the coil unit 2 is avoided.

Specifically, the cross-sectional shape of the insulating sleeve 4 may be a circular ring shape, wherein the radius of the inner circular ring corresponds to the outer diameter of the coil unit 2, that is, the inner diameter of the insulating sleeve 4 is similar to the outer diameter of the center line of the coil unit 2, so that the insulating sleeve 4 and the line segment unit are better adapted. The thickness of the circular ring in the cross section of the insulating sleeve 4 is the thickness of the insulating sleeve 4, and can be adjusted according to actual needs.

Specifically, the coil unit 2 may extend along the direction of the length, width, and height of the fixed iron core 1, that is, when the coil unit 2 is wound on the fixed iron core 1, the line segment unit middle lines are all right angles when changing directions, so as to be more adaptive to the fixed iron core 1.
