[0059] In addition, in the embodiment, the bus bar end cover 110 is provided with strip-shaped through holes 114 with the same number of teeth in the circumferential direction. Taking the stator with 12 teeth as an example, 12 strip-shaped through holes 114 are provided, and the outer circumferential surface of the strip-shaped through hole 114 is flush with the outer circumferential surface of the bus bar end cover 110. The bus bar clamps 115 of the V-phase bus bar 112 and the W-phase bus bar 113 are exposed in the strip-shaped hole, and the visual appearance presents a suspended state.

[0060] Please refer to Figures 1-12 The working principle of the compression motor stator insulation end cover assembly 100 is as follows:

[0061] The compression motor stator insulation end cover assembly 100 comprises a bus bar end cover 110 and an insulation skeleton 130. The bus bar end cover 110 and the insulation skeleton 130 are detachably connected, and when applied to the compressor motor stator, the insulation skeleton 130 is connected with the stator core 210 of the compressor stator.

[0062] When the bus bar end cover 110 is arranged, the bus bar end cover 110 comprises an end cover body 111, a V-phase bus bar 112 and a W-phase bus bar 113. The end cover body 111 is provided with a plurality of strip-shaped through holes 114 filled with potting glue 101 around the axis thereof. The V-phase bus bar 112 and the W-phase bus bar 113 are arranged in the end cover body 111, and the bus bar clamps 115 of the V-phase bus bar 112 and the W-phase bus bar 113 correspondingly extend into a strip-shaped through hole 114. That is, by this way, the V-phase bus bar 112 and the W-phase bus bar 113 are connected to the end cover body 111 by injection molding, and a plurality of strip-shaped through holes 114 are arranged on the end cover body 111, and the bus bar clamps 115 of the V-phase bus bar 112 and the W-phase bus bar 113 correspondingly extend into the strip-shaped through hole 114.

[0063] When the insulation framework 130 is configured, the insulation framework 130 comprises a framework body 131, a neutral point busbar 132, a U-phase busbar 133 and a plurality of terminal connectors 134; the neutral point busbar 132 and the U-phase busbar 133 extending around the axis of the framework body 131 are arranged in the framework body 131; the plurality of terminal connectors 134 are connected with the framework body 131 and are arranged at intervals around the axis of the framework body 131, the neutral point busbar 132 and the U-phase busbar 133 are connected with the corresponding terminal connectors 134, and each terminal connector 134 extends into a corresponding strip-shaped through hole 114 and is connected with a corresponding busbar clamp 115; through such a setting mode, the neutral point busbar 132 and the U-phase busbar 133 are arranged in the framework body 131 in an injection-molded manner, and the terminal connectors 134 can also be connected with the framework body 131 in an injection-molded manner, and when the terminal connectors 134 are configured, part of them protrude towards the direction of the end cover body 111 and extend into the corresponding strip-shaped through hole 114;

[0064] When the above-mentioned busbar end cover 110 and the insulation framework 130 are connected, the framework body 131 and the end cover body 111 are detachably connected, and based on the above-mentioned structure, according to a predetermined wiring rule, the terminal connectors 134 are connected with the wire heads 212 or the wire tails 213 of the coils 211 extending into the strip-shaped through holes 114, or the terminal connectors 134 are connected with the U-phase wires, the V-phase wires or the W-phase wires extending into the strip-shaped through holes 114.

[0065] In the above-mentioned structure, when the terminal connectors 134, the U-phase busbar 133, the V-phase busbar 112, the W-phase busbar 113 and the neutral point busbar 132 are configured, the terminal connectors 134, the U-phase busbar 133, the V-phase busbar 112, the W-phase busbar 113 and the neutral point busbar 132 can all be arc-shaped metal pieces made of copper plates, which are surface-plated with tin, and then are assembled into the end cover body 111 and the framework body 131 respectively and are connected through injection molding; and the end cover body 111 and the framework body 131 are injection-molded products made of engineering plastics;

[0066] As can be known from the above-mentioned content, the neutral point busbar 132, the terminal connectors 134 and the U-phase busbar 133 extend around the axis of the framework body 131 in a specific arrangement order and are injection-molded into an integral structure with the framework body 131, which are commonly referred to as the former as the core piece in the industry; and the V-phase busbar 112 and the W-phase busbar 113 are made by the same process and are surface-plated with tin, and are injection-molded into an integral structure with the end cover body 111 in a specific arrangement order;

[0067] Therefore, through the above structural arrangement, during assembly, the coil 211 and the three-phase wire 220 are inserted into the corresponding strip-shaped channels and connected with the corresponding wire terminals 134, and then the corresponding assembly process is completed, thereby reducing the manual assembly process during assembly, and such an arrangement can also improve the insulation performance through the end cover body 111 and the framework body 131 and the potting glue 101 filled into the strip-shaped through holes 114. Therefore, the compression motor stator insulation end cover assembly 100 is applied to the compression motor stator 200 of the compression motor, which can reduce manual processes, improve production efficiency and product consistency, and also improve insulation protection performance.

[0068] Further, please refer to Figures 1-12 In this embodiment, when the end cover body 111 is connected with the framework body 131, the framework body 131 blocks all the strip-shaped through holes 114 close to one end of the framework body 131. Such an arrangement is to block the bottom of each strip-shaped through hole 114, thereby facilitating the filling of the potting glue 101 into the interior.

[0069] Based on the above structure, please refer to Figures 1-16 The framework body 131 is also provided with a plurality of wire posts 135, which are arranged at intervals around the axis of the insulation framework 130. Each wire terminal 134 is provided with a wire post 135 on one side around the axis of the insulation framework 130. The wire head 212 or the wire tail 213 of the coil 211 connected to the wire terminal 134 is wound around the corresponding wire post 135. Through the foregoing structural arrangement, when the wire head 212 or the wire tail 213 of the coil 211 is connected with the wire terminal 134, since the wire head 212 and the wire tail 213 of the coil 211 are riveted with the busbar or the U-shaped groove of the wire terminal 134, and then a stable low-resistance path is formed by using the soldering process. Before riveting with the U-shaped groove, the enameled wire must pass through the wire post 135, which is to lengthen the path of the soldering place and the coil 211 winding. During high-temperature soldering, high temperature can cause the enameled wire near the soldering place to burst, thereby preventing the burst enameled wire from being too close to the coil 211, which can reduce the insulation performance.

[0070] When the busbar end cover 110 and the insulating framework 130 are connected, the embodiment adopts the mode that the plurality of clamping grooves 136 are arranged on the outer periphery of the framework body 131 around the axis, the plurality of reverse buckles 116 are arranged on the end cover body 111 around the axis, and the framework body 131 is connected to the end cover body 111 by the mode that each reverse buckle 116 is clamped to a clamping groove 136. It should be noted that the number of clamping grooves 136 and clamping buckles is equal along the circumferential direction, that is, the stator structure is 12 teeth, that is, there are 12 clamping buckle points, so that the stress is evenly distributed to prevent warping.

[0071] Moreover, when the busbar end cover 110 and the insulating framework 130 are connected, in order to improve the connection efficiency of the framework body 131 and the end cover body 111, the end cover body 111 is provided with a boss 117 which is inserted into the end cover body 111, and the outer side of the boss 117 is provided with an arc chamfer 118, so as to play a role of assembly guide in this way.

[0072] Moreover, the boss 117 is provided with a plurality of wire grooves 119, each of which is used for the wire head 212 or the wire tail 213 of the coil 211 to pass through, and the wire groove 119 is an inverted V groove. The position of the wire groove 119 on the boss 117 corresponds to the vertical section of the wire head 212 and the wire tail 213, and the groove depth of the wire groove 119 is slightly higher than the height of one enameled wire diameter of the axial end face of the insulating framework 130, so as to make the vertical section of the wire head 212 and the wire tail 213 of the coil 211 smoothly slide into the wire groove 119 when the busbar end cover 110 is assembled, and the wire groove 119 can avoid interference with the wire head 212 and the wire tail 213 after assembly, and can also form a block with the insulating framework 130, so as to facilitate the filling of the potting glue 101 in the subsequent process.

[0073] Please refer to Figures 1-18 When the three-phase wire 220 is connected to the wire terminal 134, the embodiment adopts the mode that the U-phase wire, the V-phase wire and the W-phase wire are connected to one wire harness terminal 150 at one end extending into the corresponding strip-shaped through hole 114, and the wire harness terminal 150 is connected to the corresponding wire terminal 134 in the same strip-shaped through hole 114. Moreover, each strip-shaped through hole 114 is provided with a semi-cylinder 121, and the side surface of the wire harness terminal 150 is provided with a positioning groove 151 which is positioned and matched with the semi-cylinder 121.

[0074] The wire harness terminal 150 is made of copper plate stamping into an arc-shaped metal piece, and the surface is tin-plated; since the busbar end cover 110 needs to be assembled after the completion of the three-phase wire, in order to optimize the wiring efficiency, the wire harness terminal 150 is pre-riveted and welded at the wire harness end of the U-phase wire, the V-phase wire and the W-phase wire, and the wire harness terminal 150 is provided with an arc groove on both sides, which is in interference fit with the two semicylinders 121 arranged in the corresponding position in the strip-shaped through hole 114 of the busbar end cover 110 in the form of riveting, and the wire harness terminal 150 is in clearance fit with the wiring terminal 134, and the tin filling is filled in the later process.

[0075] Based on the above, Figures 1-18 The embodiment also provides a compression motor stator 200 and a compression motor using the compression motor stator 200.

[0076] The compression motor stator 200 comprises a stator core 210, three-phase wires 220 and the compression motor stator insulation end cover assembly 100; the stator core 210 is connected with the frame body 131, and the wire head 212 and the wire tail 213 of the coil 211 of the stator core 210 extend into the corresponding strip-shaped through hole 114 and are connected with the corresponding wiring terminal 134.

[0077] The three-phase wires 220 comprise U-phase wires, V-phase wires and W-phase wires, and the U-phase wires, the V-phase wires and the W-phase wires extend into the corresponding strip-shaped through hole 114 and are connected with the corresponding wiring terminal 134.

[0078] Based on the above, the compression motor stator insulation end cover assembly 100, the compression motor stator 200 and the compression motor have the following advantages:

[0079] The artificial process is reduced, and the production efficiency and product consistency are improved: when the compression motor stator 200 is assembled by using the compression motor stator insulation end cover assembly 100, the worker only needs to remove the paint of the wire head 212 and the wire tail 213 of the coil 211 and rivet them to the corresponding wiring terminal 134 or busbar after taking the completed winding stator from the winding machine, and does not need to thread the insulation tube for the enameled wire and does not need to untangle and bundle the enameled wire, and only needs to assemble the busbar end cover 110 to the insulation, so that the artificial process can be greatly reduced, the production efficiency and product consistency are improved.

[0080] In addition, compared with the prior art, the compression motor stator insulation end cover assembly 100 improves the integration degree of the insulation frame 130, and adds the busbar end cover 110 which is also highly integrated, uses the plastic packaging process instead of the complicated artificial process, fully utilizes the internal space of the injection molding part, reduces the number of product parts and process flow, improves the production efficiency, reduces the product difference degree caused by different methods of workers, and improves the consistency of products.

[0081] Improve the insulation performance: the neutral busbar 132 and U-phase busbar 133 are buried in the insulation skeleton 130, and are completely isolated from the outside, so as to meet the performance requirements of high-strength insulation; similarly, the V-phase busbar 112 and W-phase busbar 113 are also buried in the busbar end cover 110, and are completely isolated from the outside, so as to form high-strength insulation performance;

[0082] Furthermore, after the busbar end cover 110 is assembled to the insulation skeleton 130, the bottom of the strip-shaped through hole 114 on the busbar end cover 110 is blocked by the insulation skeleton 130, so that the strip-shaped through hole 114 forms a plurality of surrounding grooves with the same number of teeth, and the wire harness terminal 150, the wiring terminal 134 and the busbar clamp 115 in the surrounding grooves are filled with the filling glue 101 after the soldering process is completed, so as to completely wrap the wiring terminal 134 and the wire harness terminal 150, isolate them from the outside, and meet the performance requirements of high-strength insulation.
