Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of motor structure, and particularly relates to a stator assembly and a motor. BACKGROUND

[0002] In the manufacturing system of a compressor, a motor is a core driving component, and the performance and reliability of the motor directly determine the working efficiency and service life of the whole machine. A mainstream electromagnetic structure composed of a stator and a rotor is generally used in the motor. The stator is a static part, and its core function is to generate a rotating magnetic field. The stator is usually composed of a laminated silicon steel sheet, and copper wire windings are embedded in the slots of the stator core. These winding coils are arranged according to a specific number of poles and a specific number of phases, and finally form a ring-shaped current path on the stator core, which is the basis for realizing the conversion of electric energy into mechanical energy.

[0003] After the winding is completed, a key process is to lead out the beginning and end of the winding copper wire to connect with the external power supply or controller. At present, the end of the winding copper wire itself is appropriately lengthened as a physical "lead-out wire". The advantage of this method is that the structure is simple, and the material cost is low, and no additional connecting parts are needed. However, the lead-out wire directly made of enameled copper wire has a relatively thin diameter and soft texture, and does not have enough rigidity and shape retention ability. During the processes of stator winding, transfer and subsequent assembly, these slender wire ends are in a free state and are easily affected by inertia, vibration or air flow to produce uncontrolled swinging. The physical form cannot be fixed at the predetermined and accurate spatial position by itself, but presents a random posture, which directly leads to the fact that the lead-out wires cannot automatically present in a neat and accurate position when they need to be connected to the next connection link. A large number of manual intervention links are introduced on the production line, and the workers need to identify these swinging wire ends one by one, and use manual methods to straighten and collect them, and accurately insert them into the plastic wiring buckle or wire slot installed at the end or near the stator. The above process seriously depends on workers, and directly drags the overall production rhythm. Especially on the modern high-speed production line with compact design rhythm, this bottleneck effect is further magnified, and becomes a significant obstacle to the improvement of production capacity.

[0004] To address the problems caused by direct leads, a separate "lead assembly" is pre-connected to the end of the winding copper wire. This assembly typically contains lead wires with a larger cross-sectional area and stronger insulation. This method enhances the mechanical strength of the lead end, making the wire shape relatively easier to control. The lead assembly itself is still a loose component outside the stator body. Before the stator flows into subsequent processes, it must be firmly bound to the support. Operators need to use materials such as cable ties and ropes to manually bind the lead assembly to the designated position on the stator shell. In practice, workers often need to hold the lead assembly in place with one hand while binding it with the other, which is difficult, slow, consumes production time, and increases labor costs.

[0005] Whether using directly extended copper wires as lead wires or adding independent lead wire assemblies, the existing process still relies on intensive manual operation in the lead wire installation stage. This not only greatly reduces the automation level of the compressor motor stator production section, making it difficult to integrate into a fully automated unmanned production line, but also directly leads to the extension of production cycle time, the reduction of overall production efficiency, and quality fluctuations caused by differences in human operation due to the inherent speed limitations and variability of manual operation. Summary of the Invention

[0006] The purpose of this invention is to provide a stator assembly and motor that solves the problem that in the production process of stator assemblies, the winding copper wires and lead wires need to be manually bound with wires during the interconnection process, which is time-consuming and leads to a reduction in production cycle time.

DETAILED DESCRIPTION

[0020] The present application will be further described below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the convenience of description, only the parts related to the present application are shown in the drawings, but not all the structures.

[0021] In the description of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0022] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0024] Currently, compressors contain motors, and the mainstream structure of motors includes stators. The copper wires winding inside the stator are looped around a support. Usually, the ends of the copper wires are extended directly as leads for the electronic structure. However, these leads are typically quite thin and tend to swing back and forth during processing, making it impossible to fix them in the preset position. Manual connection is required before proceeding to the next process, where each copper wire is inserted into a plastic clip at the end. This results in low automation of the compressor production line, delays production cycle, and reduced production efficiency. Alternatively, lead wire assemblies can be installed at the ends of the winding copper wires to connect them to the leads. However, after installing the lead wire assemblies, they still need to be tied to the stator support. This manual tying process is time-consuming, and errors in the tying position can occur, requiring manual adjustment and placement. This process also reduces production efficiency.

[0025] To solve the above problems, such as Figures 1 to 10 As shown, the present invention provides a stator assembly, on the inner side of which a rotor is mounted. The stator assembly and the rotor are installed together inside the motor. The assembly includes a stator bracket 1 and a lead-out member 2 mounted on the stator. A winding 3 is wound around the stator bracket 1 and the stator. A lead-out wire is provided inside the winding 3. The lead-out wire is electrically connected to the lead-out member 2. A first fixing part 4 is mounted on the lead-out member 2. A second fixing part 5 is provided on the stator bracket 1. The first fixing part 4 and the second fixing part 5 are engaged by a plug-in connection or by a snap-fit ​​connection.

[0026] By installing the first fixing part 4 on the lead-out piece 2 and arranging the second fixing part 5 on the stator support 1, the step of establishing the connection relationship between the lead-out piece 2 and the stator support 1 is simplified, the production efficiency is improved, and the production rhythm is shortened, and it needs to be particularly pointed out that the first fixing part 4 and the second fixing part 5 of the application are connected in the form of insertion, but are not limited to the form of insertion, and can also be connected in the form of mortise and tenon or buckle. Compared with the form of binding, the connection time can be reduced, the goal of quick fixing can be achieved, the connection processing time is shortened, and at the same time, due to the simple connection process, the above-mentioned connection forms can be operated by machines instead of manual operation. In the connection process, a simple mechanism with telescopic ability can be used to cooperate the first fixing part 4 and the second fixing part 5, the production rhythm is shortened, the production efficiency is improved, and the stator support 1 and the lead-out piece 2 can be directly connected in the form of insertion.

[0027] The lead-out piece 2 comprises an adapter 21 and an adapter wire 22, one end of the adapter wire 22 is inserted into the adapter 21, the other end of the adapter wire 22 is connected with a lead-out wire, and the first fixing part 4 is arranged on the adapter wire 22. The first fixing part 4 of the application is arranged on the adapter wire 22, and the adapter wire 22 shown in the application comprises three groups, the three groups of adapter wires 22 are arranged in the same group of adapters 21, and the three groups of lead-out wires can be fixed through the connection of the first fixing part 4 and the lead-out wire. The first fixing part 4 can be connected with the second fixing part 5 while fixing the lead-out wire, and multiple functions are integrated on the first fixing part 4, so that the function integration of the first fixing part 4 is more concentrated.

[0028] The adapter wire 22 is bound with a fixing rope 6, and the first fixing part 4 is also bound in the fixing rope 6. Usually, the adapter wire 22 is provided with three groups of fixing ropes 6, and the fixing rope 6 closest to the stator support 1 can be used with a group of fixing ropes 6, so that the modification degree of the application is reduced, and the difficulty of modification is reduced. It needs to be particularly pointed out that the fixing rope 6 of the application can also be a binding member such as a cable tie, and the same effect of the fixing rope 6 can also be achieved.

[0029] The second fixing part 5 of the application is integrally formed with the stator support 1, which can improve the connection cost of the second fixing part 5 and the stator support 1 and improve the structural connection strength.

[0030] The end of the first fixing part 4 away from the second fixing part 5 is provided with a binding end, the binding end is circumferentially recessed to form a binding groove 7, the fixing rope 6 is wound in the binding groove 7, and the second fixing part 5 abuts the lower side of the binding end. In order to avoid the fixing rope 6 from moving back and forth along the radial direction of the first fixing part 4, the fixing rope 6 is arranged in the binding groove 7, so that the fixing rope 6 can be fixed in the binding groove 7, and the fixing rope 6 is prevented from moving back and forth.

[0031] As Figure 11As shown, a plurality of limiting protrusions 8 can be arranged in the circumference of the binding end, and a binding material such as a fixing rope 6 is bound between the limiting protrusions 8, and anti-skid lines 9 are arranged on the surface between the limiting protrusions 8, which can avoid the fixing rope 6 from moving along the axis of the first fixing portion 4, and the limiting protrusions 8 can avoid the fixing rope 6 from separating from the first fixing portion 4, thereby limiting the fixing rope 6.

[0032] For the stator support 1 of the multi-phase motor having a plurality of outgoing wires, the position of the second fixing portion 5 is located in the middle of the outgoing wires, which can avoid the outgoing distance of a single outgoing wire being too long, reduce the resistance, and reduce the material usage.

[0033] Embodiment one As shown in Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 10 , the second fixing portion 5 is formed with a second plug-in hole 51, and the first fixing portion 4 is plugged into the second plug-in hole 51, in order to reduce the plugging difficulty, the first plug-in hole 43 and the first fixing portion 4 are both main bodies, and it is particularly noted that the shapes of the second plug-in hole 51 and the first fixing portion 4 are the same and are not limited to a cylinder, and the cross section can also be other shapes, and the second plug-in hole 51 and the first fixing portion 4 are in interference fit, thereby connecting the first fixing portion 4 and the second fixing portion 5.

[0034] The first fixing portion 4 is provided with a first tapered head 41, and the front end of the first tapered head 41 is provided with a first deformation groove 42, and the first deformation groove 42 is open towards the second fixing portion 5.

[0035] Since the front end of the first fixing portion 4 is the first tapered head 41, during the plugging of the first fixing portion 4 into the second plug-in hole 51, the outer wall of the second plug-in hole 51 and the first tapered head 41 will be deformed, in order to avoid the risk of the deformation of the outer wall of the second plug-in hole 51 and the first tapered head 41 being too large and causing breakage, the first deformation groove 42 is arranged in the radial direction of the first tapered head 41, which can make the first tapered head 41 contract inwardly during the entering process of the first tapered head 41, and when the first tapered head 41 passes through the second plug-in hole 51, the first deformation groove 42 in the first tapered head 41 will be expanded again, and the flange on the upper side of the first tapered head 41 will abut against the lower side of the limiting boss, and an annular protrusion is usually arranged in the second plug-in hole 51, which usually has a certain height to provide limiting force.

[0036] A second deformation groove 52 is arranged on the second insertion hole 51, and the opening of the second deformation groove 52 faces the first fixing part 4. During the insertion of the first tapered head 41, the second deformation groove 52 is expanded, so that the first tapered head 41 can be smoothly inserted. After the first tapered head 41 passes the limiting boss, the second deformation groove 52 is contracted inward, so that the limiting boss can abut against the upper side of the first tapered head 41.

[0037] By slotting the first tapered head 41 or the second insertion hole 51 or both, the difficulty of inserting the first fixing part 4 into the second insertion hole 51 can be reduced, and the fixation of the second fixing part 5 to the first fixing part 4 can be realized after the insertion, thereby reducing the difficulty of insertion. The second fixing part 5 of the application is integrally formed with the stator support 1, which can improve the connection cost of the second fixing part 5 and the stator support 1 and improve the structural connection strength.

[0038] Embodiment two As shown in Figure 3 , Figure 4 , Figure 8 and Figure 9 , the first fixing part 4 is provided with a first insertion hole 43, and the second fixing part 5 is inserted into the first insertion hole 43. In this embodiment, the first fixing part 4 is a structure with a hole, and the second fixing part 5 is a column structure. The first fixing part 4 is sleeved on the outer side of the second fixing part 5, thereby realizing the quick connection of the first fixing part 4 and the second fixing part 5. The first fixing part 4 and the second fixing part 5 are both column structures, which can reduce the difficulty of insertion and facilitate processing and forming.

[0039] The top of the second fixing part 5 is provided with a second tapered head 53, and the front end of the second tapered head 53 is provided with a third deformation groove 54. The opening of the third deformation groove 54 faces the first fixing part 4. During the mutual approach and insertion of the first fixing part 4 and the second fixing part 5, the second tapered head 53 is contracted inward by the third deformation groove 54 in the first fixing part 4 under the pushing of the limiting boss on the inner side of the first fixing part 4, so that the second fixing part 5 can be inserted into the first fixing part 4. After the second tapered head 53 passes the limiting boss, the third deformation groove 54 is expanded, and the lower edge of the second tapered head 53 abuts against the upper side of the limiting boss, so that the first fixing part 4 and the second fixing part 5 can be finally installed and locked in place, and the first fixing part 4 and the second fixing part 5 can be stably connected.

[0040] The first insertion hole 43 of the present invention is provided with a fourth deformation groove 44. The opening of the fourth deformation groove 44 faces the second fixing part 5. After the limiting boss in the first fixing part 4 contacts the second conical head 53, the first fixing part 4 will open along the fourth deformation groove 44, so that the second conical head 53 can be inserted into the first fixing part 4. After the second conical head 53 passes through the annular limiting boss, the opening of the fourth deformation groove 44 returns to its original state, so that the limiting boss can be engaged with the lower side of the second conical head 53, thereby realizing the connection between the first fixing part 4 and the second fixing part 5.

[0041] The third deformation groove 54 and the fourth deformation groove 44 of the present invention can exist simultaneously or independently. By providing the third deformation groove 54 and the fourth deformation groove 44, deformation is avoided during the docking process of the first fixing part 4 and the second fixing part 5. The third deformation groove 54 and the fourth deformation groove 44 can make the first fixing part 4 and the second fixing part 5 more malleable.

[0042] In Embodiment 1 and Embodiment 2, the first fixing part 4 and the second fixing part 5 are made of elastic material. When the first conical head 41 and the second conical head 53 abut against each other, the first fixing part 4 and the second fixing part 5 can undergo elastic deformation and eventually return to their original shape to achieve the connection between the first fixing part 4 and the second fixing part 5.

[0043] The second insertion hole 51 of the present invention can be injection molded on the stator support 1 as a through hole that is closed at one end or open on both sides. Different forms of stator support 1 can be adapted to different forms of second insertion holes 51.

[0044] In Embodiment 1 and Embodiment 2, the inner diameter of the limiting boss is 1mm, while the diameter of the first insertion hole 43 and the second insertion hole 51 is 2mm, so that the first fixing part 4 and the second fixing part 5 can lock each other after the connection is completed.

[0045] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here.
