[0041] The invention provides a motor and a compressor.

[0042] Reference Figures 1 to 3 The motor comprises an insulating support 1, a terminal seat 2, a crimping terminal 3, a protrusion 4 and a lead shell 5. The terminal seat 2 is arranged on the insulating support 1, and has a plurality of terminal cavities 21 distributed at intervals in the terminal seat 2, each terminal cavity 21 is provided with a crimping terminal 3, the lead shell 5 is plugged with the terminal seat 2, and the lead shell 5 is provided with a plug-in terminal 7 inserted into the terminal cavity 21; the protrusion 4 is arranged on the terminal seat 2, and when the lead shell 5 is plugged with the terminal seat 2, the protrusion 4 is clamped and fixed with the lead shell 5.

[0043] Specifically, the insulating support 1 is annular, and the terminal seat 2 is embedded in the outer peripheral wall of the insulating support 1. The two can be fixed by welding or bonding, or they can be integrated with the insulating support 1. The top wall of the terminal seat 2 is open as a socket 22 of each terminal cavity 21, and the crimping terminal 3 is arranged in the terminal cavity 21. The lead shell 5 has a connecting cavity, the terminal seat 2 can be inserted into the connecting cavity, and the inner wall of the lead shell 5 can wrap the outer wall of the terminal seat 2. The plug-in terminal 7 is plate-shaped and extends in the vertical direction. It is fixed on the bottom wall of the connecting cavity and is arranged one by one with the crimping terminal 3. A protrusion 4 can be set on the front side of the terminal seat 2, so that when the lead shell 5 is plugged into the terminal seat 2, when the plug-in terminal 7 is inserted into the terminal cavity 21 and cooperates with the crimping terminal 3, the protrusion 4 can form a snap connection with the lead shell 5, thereby fixing the lead shell 5 and the terminal seat 2 together.

[0044] By providing the protrusion 4 on the terminal seat 2, it can be clamped and fixed with the lead shell 5 when the lead shell 5 is plugged into the terminal seat 2. At this time, the plug-in terminal 7 will be inserted into the terminal cavity 21 to form a match with the crimping terminal 3, so that the lead shell 5 can be quickly plugged into the terminal seat 2 and the two can be assembled. In this way, the assembly process of the lead shell 5 and the terminal seat 2 can be effectively simplified, the assembly efficiency of the two can be improved, and the overall assembly efficiency of the motor can be improved, ensuring that the production rhythm of the motor remains stable.

[0045] Reference Figure 3 and Figure 4 In some embodiments of the present invention, two protrusions 4 are arranged at intervals. The side of the protrusion 4 that is inserted into the lead housing 5 has a connecting slope 41. The inner side of the lead housing 5 is provided with a plug chamfer 52, which is adapted to the connecting slope 41. The lead housing 5 has a snap-fit ​​notch 51 that snaps with the protrusion 4.

[0046] Specifically, the protrusion 4 is block-shaped and is arranged on the outer side wall of the terminal block 2 away from the insulating bracket 1. The side channel of the protrusion 4 is chamfered to form a connecting inclined surface 41, and the connecting inclined surface 41 is arranged toward the side where the lead shell 5 is inserted. A corresponding snap-fit ​​notch 51 is opened on the lead shell 5 to smoothly form a snap-fit ​​with the protrusion 4, thereby improving the assembly stability of the lead wire assembly and the terminal shell 24. The specific inclination angle of the connecting inclined surface 41 and the number of protrusions 4 can be designed according to the actual size of the terminal block 2, and this application does not limit this.

[0047] Reference Figure 3 , Figure 4 and Figure 5 In some embodiments of the present invention, the motor includes a guide column 6. The guide column 6 is arranged on the side of the lead shell 5 opposite to the plug-in chamfer 52, and the lead shell 5 is plugged with the terminal block 2. The side close to the plug-in chamfer 52 is wrapped around the outside of the terminal block 2, and the side close to the guide column 6 is connected by inserting the guide column 6 into the terminal cavity 21. The side of the guide column 6 is provided with a limiting chamfer 61 facing the terminal block 2. Two guide columns 6 are distributed at intervals. The depth of the limiting chamfer 61 is greater than the plug-in chamfer 52. Specifically, the depth of the limiting chamfer 61 toward the lead shell 5 is greater than the plug-in chamfer 52, that is, the distance between one end of the limiting chamfer 61 facing the shell top of the lead shell 5 and the shell top is less than the distance between one end of the plug-in chamfer 52 facing the shell top of the lead shell 5 and the shell top.

[0048] Specifically, the guide post 6 is fixed to the side of the lead housing 5 in the vertical direction, and a chamfer is set at one end away from the lead housing 5 as a limit chamfer 61, and a chamfer is also set at the inner side of the lead housing 5 and close to the opening as a plug chamfer 52. The apex of the wrapped portion 53 of the lead housing 5 wrapped around the outside of the terminal block 2 is higher than the apex of the guide post 6, and the apex of the guide post 6 is higher than the apex of the plug chamfer 52.

[0049] The following will introduce the plugging process of the lead shell 5 in combination with the dimensions of the limiting chamfer 52 and the plugging chamfer 61 in this embodiment. Because during the plugging process of the lead shell 5, the side with the snap-in notch 51 will be subjected to a greater force and there may be a risk of bursting. In this embodiment, the inclination amplitude of the plugging chamfer 52 is set consistent with the connecting bevel 41 of the protrusion 4, so that the two are complementary when they are connected together, avoiding excessive outward squeezing of the lead shell 5 by the outer wall of the terminal seat 2 when the lead shell 5 wraps the terminal seat 2. At the same time, the depth of the limiting chamfer 61 is increased to reduce the force on the wrapped portion 53 of the lead shell 5 at the same transverse cross-sectional position. Please refer to the details. Figure 5 During the insertion of the lead shell 5, the lead shell 5 as a whole will first contact the terminal seat 2, that is, the wrapping portion 53 is wrapped around the outside of the terminal seat 2 and inserted. When the insertion depth a is reached, the limit chamfer 61 of the guide column 6 contacts the terminal seat 2 and is inserted between the inner wall of the terminal seat 2 and the crimping terminal 3. After continuing to insert to a depth b, the plug-in chamfer 52 contacts the connecting inclined surface 41 of the protrusion 4. After being inserted to a certain depth, the protrusion 4 will pass over the plug-in chamfer 52 and be snapped into the corresponding snap-in notch 51, thereby realizing the plug-in fixation of the lead shell 5 and the terminal seat 2.

[0050] In the process of the protrusion 4 passing over the plug chamfer 52, because the depth of the limiting chamfer 61 is greater than the plug chamfer 52, the force on the wrapped portion 53 with the same cross section as the limiting chamfer 61 is greatly reduced, and the force-bearing length of the wrapped portion 53 is reduced as a whole, thereby effectively reducing the possibility of the lead shell 5 being broken and damaged during the plugging process. When the lead shell 5 is wrapped and inserted into the terminal seat 2, the plug-in terminal 7 is plugged into the crimping terminal 3 and fixed by other guide positions, which can not only accurately insert once, but also avoid damage.

[0051] Reference Figure 6 In some embodiments of the present invention, the crimping terminal 3 includes a terminal frame 32 and a terminal block 33. The terminal frame 32 is arranged in the terminal cavity 21; the terminal block 33 is arranged on a side of the terminal frame 32 close to the socket 22, and the terminal block 33 is inclined to form a guide inclined surface 31 that slides with the plug-in terminal 7.

[0052] Specifically, the terminal frame 32 is U-shaped, and a through hole is provided at the bottom thereof for the lead wire to be inserted therein. The terminal block 33 is plate-shaped, and one side thereof is fixed to the side of the terminal frame 32 close to the socket 22 as a fixed side, and the other side is extended downwardly as a free side, and an upwardly extending avoidance groove can be provided in the middle of the free side to avoid the lead wire. A triangular reinforcement block can also be provided on the side of the terminal block 33 away from the socket 22 to improve the overall strength of the terminal block 33.

[0053] Reference Figure 2In some embodiments of the present invention, the terminal block 2 includes a terminal shell 24 and a plurality of partitions 25. The terminal shell 24 is fixed to the insulating bracket 1, and the lead shell 5 is wrapped around the outside of the terminal shell 24, and the matching surface between the two is an arc surface. The plurality of partitions 25 are distributed in the terminal shell 24 at intervals, and a terminal cavity 21 is formed between two adjacent partitions 25.

[0054] Specifically, the terminal shell 24 is in the shape of an elongated strip and hollow inside. The partition 25 is arranged in the vertical direction and fixed in the terminal shell 24 at equal intervals along the length direction of the terminal shell 24. The lower side of the partition 25 is fixedly connected to the inner lower wall of the terminal shell 24, and the upper side of the partition 25 extends toward the socket 22. Two partitions 25 can be provided to form three terminal cavities 21 in the terminal shell 24. A crimping terminal 3 is correspondingly arranged in each of the three terminal cavities 21, which respectively correspond to the three-phase outlet terminals of U, V, and W. The terminal frames 32 of the three crimping terminals 3 can be integrated, and a notch is provided on the corresponding partition 25 for the terminal frame 32 to be inserted, and a terminal block 33 is correspondingly arranged in the portion of the terminal frame 32 located in the terminal cavity 21.
