There is a difference in the structure of the two sub-frames, and usually multiple sets of molds are required for injection molding. In the actual implementation process, the mold cost is relatively high.

[0020] Combined with Figure 1-4 As shown, the technical solution is further described. The stator coil insulating skeleton includes a skeleton body 1, and a first connecting member 2 and a second connecting member 3 which are arranged on the skeleton body 1 in sequence along the circumferential direction. An angle A is set between the first connecting member 2 and the second connecting member 3. The first connecting member 2 is provided with a first accommodating cavity 4 which matches the second connecting member 3. When the two skeleton bodies 1 are arranged relative to each other, the second connecting member 3 between the two skeleton bodies 1 can be matched and extended into the first accommodating cavity 4 to connect the two skeleton bodies 1 to each other.

[0021] The present application provides a stator coil insulation frame, including a frame body, and a first connector and a second connector sequentially arranged on the frame body in a circumferential direction. By setting an angle A between the first connector and the second connector, the first connector is provided with a first accommodating cavity matching the second connector, so that after the two frame bodies are relatively arranged and relatively rotated by a degree corresponding to the angle A, the second connector between the two frame bodies can be matched and extended into the first accommodating cavity, so that the two frame bodies are connected to each other, and the two frame bodies share a set of molds, without using multiple sets of molds, which greatly reduces the production cost of the stator, and has the advantages of simple structure, easy assembly, and easy promotion and implementation.

[0022] In the actual implementation process, the second connecting member is provided with a second accommodating cavity. By providing a hollow second accommodating cavity, the consumption of resin raw materials during the injection molding process can be reduced, and the manufacturing cost of the insulating frame can be further saved.

[0023] The cross-sectional shape of the second connecting member is the same as the cross-sectional shape of the first accommodating cavity. When the two skeleton bodies 1 are arranged relative to each other, after the two skeleton bodies 1 are relatively rotated by an angle corresponding to the angle A, the second connecting member 3 between the two skeleton bodies can be matched and extended into the first accommodating cavity 4 to connect the two skeleton bodies 1 to each other. The two skeleton bodies share a set of molds without the need to use multiple sets of molds, which greatly reduces the production cost of the stator and has the advantages of simple structure, easy assembly, and easy promotion and implementation.

[0024] Preferably, a winding assembly 5 for winding is provided between the first connecting member 2 and the second connecting member 3, and the winding assembly 5 includes a first winding groove 50 provided between the first connecting member 2 and the second connecting member 3, a protrusion 51 extending along the height direction of the skeleton body 1 and away from the first connecting member 2, and a second winding groove 52 provided on the protrusion 51 and connected to the first winding groove 50.

[0025] Preferably, the first winding groove 50 is perpendicular to the second winding groove 52 .

[0026] Preferably, the first winding groove 50 includes a straight portion 500 arranged along the radial direction of the skeleton body 1 , and an arcuate portion 501 arranged on the straight portion 500 and away from the axis of the skeleton body 1 .

[0027] During the actual implementation, a winding assembly is provided, and the first winding groove and the second winding groove cooperate to allow the wire to be wound around the skeleton body, thereby improving the winding stability of the insulating skeleton.

[0028] Preferably, a limiting convex edge 6 is provided along the inner wall of the bottom of the first accommodating cavity 4. When the second connecting member 3 between the two skeleton bodies 1 matches and extends into the first accommodating cavity 4, the limiting convex edge 6 can abut against the second connecting member 3 to limit the movement of the second connecting member 3 along the height direction of the first accommodating cavity 4.

[0029] During the actual implementation process, by setting a limiting convex edge, the convenience of assembly between the two skeleton main bodies is improved. When the two are against each other at the limiting convex edge, the assembly can be completed, which makes it easier to judge the assembly progress and improves the convenience of assembly.

[0030] Preferably, the cross-section of the skeleton body 1 is circular, the cross-sections of the first connecting member 2 and the second connecting member 3 are trapezoidal, and the widths of the cross-sections of the first connecting member 2 and the second connecting member 3 gradually increase from close to the axis of the skeleton body 1 to away from the axis of the skeleton body 1.

[0031] Preferably, an opening 7 is provided on one side of the first connecting member 2 close to the axis of the skeleton body 1 , and the opening 7 is communicated with the first accommodating cavity 4 .

[0033] The present application provides a stator coil insulation frame, including a frame body, and a first connector and a second connector sequentially arranged on the frame body in a circumferential direction. By setting an angle A between the first connector and the second connector, the first connector is provided with a first accommodating cavity matching the second connector, so that after the two frame bodies are relatively arranged and relatively rotated by a degree corresponding to the angle A, the second connector between the two frame bodies can be matched and extended into the first accommodating cavity, so that the two frame bodies are connected to each other, and the two frame bodies share a set of molds, without using multiple sets of molds, which greatly reduces the production cost of the stator, and has the advantages of simple structure, easy assembly, and easy promotion and implementation.
