下面将结合附图对本申请的技术方案进行清楚、完整的描述，显然，以下所描述的实施例是本申请一部分实施例，并非全部实施例。The technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only part of the embodiments of the present application, not all of the embodiments.
参考图1至图9描述本申请实施例的电机1000，该电机1000具体为无刷电机，应用于空调器等家用电器设备上，下面以具体示例对电机1000进行说明。A motor 1000 according to an embodiment of the present application is described with reference to FIGS. 1 to 9 . Specifically, the motor 1000 is a brushless motor, which is applied to household electrical appliances such as air conditioners. The motor 1000 is described below with reference to a specific example.
参照图1和图2所示，本申请实施例提供的电机1000，包括定子组件100和端盖200，定子组件100包括定子铁芯（附图未示出），通过在定子铁芯上注塑形成塑封外壳110，塑封外壳110沿定子组件100的轴向的一端敞开形成安装口101，定子组件100内侧限定出与安装口101连通的安装腔102，安装腔102用于容纳转子组件（附图未示出），转子组件转动设于安装腔102内，端盖200的中部位置设有轴承槽，用于安装转子轴承，端盖200装配到位后覆盖于安装口101，并通过转子轴承能够对转子组件进行支撑，使转子组件能够稳定运转。1 and 2 , the motor 1000 provided in the embodiment of the present application includes a stator assembly 100 and an end cover 200. The stator assembly 100 includes a stator core (not shown in the drawings). A plastic-encapsulated shell 110 is formed by injection molding on the stator core. One end of the plastic-encapsulated shell 110 along the axial direction of the stator assembly 100 is open to form an installation opening 101. An installation cavity 102 connected to the installation opening 101 is defined on the inner side of the stator assembly 100. The installation cavity 102 is used to accommodate a rotor assembly (not shown in the drawings). The rotor assembly is rotatably arranged in the installation cavity 102. A bearing groove is provided in the middle position of the end cover 200 for installing a rotor bearing. After the end cover 200 is assembled in place, it covers the installation opening 101 and can support the rotor assembly through the rotor bearing, so that the rotor assembly can operate stably.
图1所示为电机1000装配完成后的结构示意图，可以理解的是，电机1000还包括有线束300，线束300可以由电源线、信号线等导线组成，线束300需要穿过塑封外壳110进入到内部，使线束300能够与安装腔102内的电路板等部件进行电连接，因此实施例中在塑封外壳110上设置出线口131，便于线束300通过出线口131进行出线。Figure 1 is a schematic diagram of the structure of the motor 1000 after assembly. It can be understood that the motor 1000 also includes a wiring harness 300. The wiring harness 300 can be composed of conductors such as power lines and signal lines. The wiring harness 300 needs to pass through the plastic shell 110 to enter the interior so that the wiring harness 300 can be electrically connected to components such as circuit boards in the installation cavity 102. Therefore, in the embodiment, a wire outlet 131 is set on the plastic shell 110 to facilitate the wiring harness 300 to be discharged through the wire outlet 131.
结合图2可理解到，塑封外壳110位于安装口101处的端面为第一端面111，塑封外壳110的周壁沿所述定子组件100的轴向延伸形成凸出于第一端面111的凸缘130，凸缘130整体大致呈环状，出线口131设置在凸缘130上，使线束300能够从凸缘130的内侧穿过出线口131引出到外侧。而且在出线口131处设有线夹400，线夹400与出线口131匹配，通过线夹400能够夹紧导线。此外，塑封外壳110的外周壁设有安装脚120，通过安装脚120与电器设备连接，方便安装电机1000。In conjunction with FIG. 2 , it can be understood that the end face of the plastic-encapsulated housing 110 located at the installation port 101 is the first end face 111, and the peripheral wall of the plastic-encapsulated housing 110 extends along the axial direction of the stator assembly 100 to form a flange 130 protruding from the first end face 111. The flange 130 is generally annular in shape, and the outlet port 131 is arranged on the flange 130, so that the wiring harness 300 can be led out from the inner side of the flange 130 through the outlet port 131 to the outside. Moreover, a wire clamp 400 is provided at the outlet port 131, and the wire clamp 400 matches the outlet port 131, and the wire can be clamped by the wire clamp 400. In addition, the outer peripheral wall of the plastic-encapsulated housing 110 is provided with a mounting foot 120, which is connected to the electrical equipment through the mounting foot 120, so as to facilitate the installation of the motor 1000.
需要说明的是，考虑到随着搭载电机1000的家用电器等产品应用场景愈为广泛，电机1000应用环境的多样性也随之增加，因此在电机1000设计过程中需要关注在淋雨等严苛工况下的防水问题，避免出线口131位置进水而造成电机1000性能下降甚至无法正常工作。基于此，本申请实施例针对线夹400与出线口131的装配结构进行优化，有效提高电机1000的密封性，降低电机1000出现进水的现象，提升电机1000运行可靠性。It should be noted that, considering that the application scenarios of products such as household appliances equipped with motor 1000 are becoming more and more extensive, the diversity of the application environment of motor 1000 is also increasing. Therefore, in the design process of motor 1000, attention should be paid to the waterproof problem under harsh working conditions such as rain, so as to avoid water ingress at the outlet 131, which may cause the performance of motor 1000 to decline or even fail to work normally. Based on this, the embodiment of the present application optimizes the assembly structure of wire clamp 400 and outlet 131, effectively improves the sealing of motor 1000, reduces the phenomenon of water ingress into motor 1000, and improves the operating reliability of motor 1000.
参照图2和图7所示，可以理解的是，在一些实施例中，线夹400为弹性件，优选采用具有弹性的材料制作而成，具体可以是硅胶或橡胶材质，线夹400可以夹紧穿过出线口131的导线，多条电线形成线束300，线束300通过接线端子310连接成一体，线夹400对每条电线进行固定，使线束300整体得到定位。线夹400安装在出线口131内，通过挤压线夹400，使线夹400变形并与出线口131内壁紧密贴合形成密封结构，从而使线夹400与塑封外壳110之间得到有效的密封，这样线夹400既可以固定线束300，也可以起到密封作用。Referring to FIG. 2 and FIG. 7 , it can be understood that in some embodiments, the wire clamp 400 is an elastic member, preferably made of an elastic material, specifically silicone or rubber. The wire clamp 400 can clamp the wire passing through the outlet 131. Multiple wires form a wire harness 300, and the wire harness 300 is connected as a whole through the wiring terminal 310. The wire clamp 400 fixes each wire so that the wire harness 300 is positioned as a whole. The wire clamp 400 is installed in the outlet 131. By squeezing the wire clamp 400, the wire clamp 400 is deformed and closely fits with the inner wall of the outlet 131 to form a sealing structure, so that the wire clamp 400 and the plastic housing 110 are effectively sealed, so that the wire clamp 400 can not only fix the wire harness 300, but also play a sealing role.
以图9所示的实施例为示例进行说明，图9示出未装配端盖200状态的示意图，可以理解的是，凸缘130的上端面为第二端面132，线夹400朝向端盖200的端面为第三端面401，线夹400的高度大于出线口131的高度，当线夹400装配到出线口131内，第三端面401相对于第二端面132凸出，也就是说，在未装配端盖200的状态下，线夹400的上端面处于凸缘130的端面，两者之间具有高度差。由于硬度较小，端盖200与线夹400之间存在过盈量，在端盖200与凸缘130连接并装配到位后，端盖200对线夹400的上端面产生挤压，在压力作用下使线夹400发生形变，线夹400会向四周挤压出线口131的内壁，从而使线夹400与出线口131的接触面贴合更紧密，形成更加有效的密封结构，提高线夹400与定子组件100之间的密封性，有效降低电机1000在出线口131位置出现进水的风险，提升电机1000运行可靠性。The embodiment shown in FIG. 9 is used as an example for explanation. FIG. 9 shows a schematic diagram of a state where the end cover 200 is not assembled. It can be understood that the upper end face of the flange 130 is the second end face 132, and the end face of the wire clamp 400 facing the end cover 200 is the third end face 401. The height of the wire clamp 400 is greater than the height of the wire outlet 131. When the wire clamp 400 is assembled into the wire outlet 131, the third end face 401 protrudes relative to the second end face 132. That is to say, when the end cover 200 is not assembled, the upper end face of the wire clamp 400 is at the end face of the flange 130, and there is a height difference between the two. Due to the low hardness, there is an interference fit between the end cover 200 and the wire clamp 400. After the end cover 200 is connected to the flange 130 and assembled in place, the end cover 200 squeezes the upper end surface of the wire clamp 400, causing the wire clamp 400 to deform under the action of pressure. The wire clamp 400 will squeeze the inner wall of the wire outlet 131 in all directions, so that the contact surface of the wire clamp 400 and the wire outlet 131 fits more closely, forming a more effective sealing structure, improving the sealing between the wire clamp 400 and the stator assembly 100, and effectively reducing the risk of water ingress into the motor 1000 at the wire outlet 131, thereby improving the operating reliability of the motor 1000.
以硅胶材料的线夹400为示例进行说明，结合图9可理解到，线夹400通过注塑工艺成型，实施例中第三端面401相对于第二端面132凸出的高度为h，满足：h≥0.5mm，也就是说第二端面132与第三端面401的高度差需要满足大于等于0.5mm，例如，高度差可以为0.5mm、1mm等，使端盖200能够对线夹400产生足够大的挤压力，有利于提高密封性，大大提高防水性能。可理解到，若高度差过小时，线夹400产生的形变量过小而影响线夹400与出线口131之间的密封性。Taking the wire clamp 400 made of silicone material as an example, it can be understood in conjunction with FIG9 that the wire clamp 400 is formed by an injection molding process. In the embodiment, the height of the third end face 401 relative to the second end face 132 is h, which satisfies: h ≥ 0.5 mm, that is, the height difference between the second end face 132 and the third end face 401 needs to satisfy a height difference greater than or equal to 0.5 mm. For example, the height difference can be 0.5 mm, 1 mm, etc., so that the end cap 200 can generate a sufficiently large extrusion force on the wire clamp 400, which is conducive to improving the sealing and greatly improving the waterproof performance. It can be understood that if the height difference is too small, the deformation amount generated by the wire clamp 400 is too small to affect the sealing between the wire clamp 400 and the outlet 131.
需要说明的是，实施例中线夹400的弹性模量为e，满足1.2MPa≤e≤5.4MPa（兆帕）。可理解到，对弹性件施加一个外界作用力，弹性件会发生形变，弹性模量理解为单向应力状态下应力除以该方向的应变。材料在弹性变形阶段，其应力和应变成正比例关系，其比例系数称为弹性模量，根据弹性模量可衡量材料产生弹性变形难易程度的指标，其值越大，使材料发生一定弹性变形的应力也越大，即材料刚度越大，亦即在一定应力作用下，发生弹性变形越小，能够反映材料抵抗弹性变形能力的指标。通过将线夹400的弹性模量设置满足1.2MPa≤e≤5.4MPa的条件下，使线夹400具有较佳的弹性形变能力，线夹400受挤压的情况下与塑封外壳110结合更紧密。可根据不同材料及应用密封性的要求选择具体的弹性模量值，例如，线夹400为硅胶材料时弹性模量e可以是1.2 MPa、2MPa等，线夹400为橡胶材料时弹性模量e可以是3 MPa、4MPa、5.4MPa等，具体不作限定。It should be noted that the elastic modulus of the wire clamp 400 in the embodiment is e, which satisfies 1.2MPa≤e≤5.4MPa (megapascals). It can be understood that when an external force is applied to the elastic part, the elastic part will deform, and the elastic modulus is understood as the stress under unidirectional stress divided by the strain in that direction. In the elastic deformation stage of the material, its stress and strain are in a positive proportional relationship, and its proportional coefficient is called the elastic modulus. According to the elastic modulus, the index of the ease of elastic deformation of the material can be measured. The larger its value, the greater the stress that causes a certain elastic deformation of the material, that is, the greater the material stiffness, that is, under a certain stress, the smaller the elastic deformation, which can reflect the material's ability to resist elastic deformation. By setting the elastic modulus of the wire clamp 400 to meet the condition of 1.2MPa≤e≤5.4MPa, the wire clamp 400 has better elastic deformation ability, and the wire clamp 400 is more tightly combined with the plastic shell 110 when it is squeezed. The specific elastic modulus value can be selected according to the sealing requirements of different materials and applications. For example, when the wire clamp 400 is made of silicone material, the elastic modulus e can be 1.2 MPa, 2 MPa, etc., and when the wire clamp 400 is made of rubber material, the elastic modulus e can be 3 MPa, 4 MPa, 5.4 MPa, etc., without specific limitation.
可以理解的是，实施例中线夹400的硬度为c，满足：30HA≤c≤70HA，具体硬度可根据实际应用场景需求来设定，通过硬度可以反映出线夹400的抗压能力，硬度越小，线夹400越容易发生形变，反之硬度越大，线夹400越不容易发生形变，硬度过小或过大均会影响线夹400与塑封外壳110之间的密封性能。线夹400发生形变时，线夹400的侧壁与安装槽210的侧壁会形成过硬配合的结合力，线夹400采用不同的硬度，其与端盖200的结合力也会发生变化。例如，线夹400为硅胶材料时硬度可以是30HA、40HA等，线夹400为橡胶材料时硬度可以是60HA、70HA等，具体不作限定。It can be understood that the hardness of the wire clamp 400 in the embodiment is c, which satisfies: 30HA≤c≤70HA. The specific hardness can be set according to the actual application scenario requirements. The hardness can reflect the compressive resistance of the wire clamp 400. The smaller the hardness, the easier it is for the wire clamp 400 to deform. On the contrary, the greater the hardness, the less likely it is for the wire clamp 400 to deform. Too small or too large hardness will affect the sealing performance between the wire clamp 400 and the plastic package shell 110. When the wire clamp 400 is deformed, the side wall of the wire clamp 400 and the side wall of the mounting groove 210 will form a strong matching bonding force. The wire clamp 400 uses different hardness, and its bonding force with the end cover 200 will also change. For example, when the wire clamp 400 is made of silicone material, the hardness can be 30HA, 40HA, etc., and when the wire clamp 400 is made of rubber material, the hardness can be 60HA, 70HA, etc., and there is no specific limitation.
需要说明的是，结合图6可理解到，端盖200的边缘沿周向折弯形成有环形的安装槽210，凸缘130与安装槽210过盈配合，使端盖200与凸缘130连接进行紧固，从而使第一端盖200能够快速装配到定子组件100上，无需额外采用辅助部件进行固定，操作简便，端盖200装配到位后，安装槽210的底面与第二端面132抵接，在压力作用下使线夹400发生形变并与塑封外壳110形成密封。It should be noted that, in combination with Figure 6, it can be understood that the edge of the end cover 200 is bent along the circumferential direction to form an annular mounting groove 210, and the flange 130 is interference fit with the mounting groove 210, so that the end cover 200 and the flange 130 are connected and fastened, so that the first end cover 200 can be quickly assembled to the stator assembly 100 without the need for additional auxiliary components for fixing, and the operation is simple. After the end cover 200 is assembled in place, the bottom surface of the mounting groove 210 abuts against the second end surface 132, and the wire clamp 400 is deformed under the action of pressure and forms a seal with the plastic shell 110.
此外，参照图6所示，线夹400的外周壁向外延伸形成有限位部420，当线夹400固定于出线口131时，限位部420的两侧可卡接于凸缘130的外侧壁，限位部420的上侧可卡接于端盖200的外侧壁，能够在定子组件100的径向上防止线夹400出现偏移，提高线夹400装配结构的稳定性。In addition, referring to Figure 6, the outer peripheral wall of the wire clamp 400 extends outward to form a limiting portion 420. When the wire clamp 400 is fixed to the wire outlet 131, the two sides of the limiting portion 420 can be clamped to the outer side wall of the flange 130, and the upper side of the limiting portion 420 can be clamped to the outer side wall of the end cover 200, which can prevent the wire clamp 400 from being offset in the radial direction of the stator assembly 100 and improve the stability of the assembly structure of the wire clamp 400.
需要说明的是，参照图2所示，实施例中线夹400设有三个卡槽410，三个卡槽410与线夹400一体成型，装配时可将导线从线夹400的顶壁放入卡槽410内，在线夹400装配到出线口131处产生形变后，能够将导线夹400紧在卡槽410内，且形成有效的密封结构，避免水从卡槽410处进入电机1000内部。It should be noted that, referring to Figure 2, in the embodiment, the wire clamp 400 is provided with three slots 410, and the three slots 410 are integrally formed with the wire clamp 400. During assembly, the wires can be placed into the slots 410 from the top wall of the wire clamp 400. After the wire clamp 400 is assembled to the wire outlet 131 and deformed, the wire clamp 400 can be tightly fitted into the slots 410, and an effective sealing structure can be formed to prevent water from entering the interior of the motor 1000 from the slots 410.
参照图7所示，图7中示出线夹400的另一种实施例，该实施例中线夹400设有过线孔（附图未示出），线夹400的外侧壁凸出形成线束套430，线束套430与过线孔连通，且线束套430与线夹400一体成型，装配过程中，线束300穿过线束套430和过线孔后，利用扎带将线束套430扎紧，使线束套430将线束300箍紧，实现线束300和线夹400之间的密封，同时线夹400装配到位后发生形变也进一步在过线孔处形成密封，具有较佳的密封性能。Referring to Figure 7, Figure 7 shows another embodiment of the wire clamp 400. In this embodiment, the wire clamp 400 is provided with a wire through hole (not shown in the figure), and the outer wall of the wire clamp 400 protrudes to form a wire harness sleeve 430, the wire harness sleeve 430 is connected to the wire through hole, and the wire harness sleeve 430 and the wire clamp 400 are integrally formed. During the assembly process, after the wire harness 300 passes through the wire harness sleeve 430 and the wire through hole, the wire harness sleeve 430 is tightened with a cable tie so that the wire harness sleeve 430 tightens the wire harness 300 to achieve a seal between the wire harness 300 and the wire clamp 400. At the same time, the wire clamp 400 is deformed after being assembled into place to further form a seal at the wire through hole, and has better sealing performance.
考虑由于线夹400具有一定的柔性，线束300与线夹400之间存在结合力不高的问题，线束300在受到外力作用时容易出现松动、拉脱的风险。因此，本申请实施例的电机1000通过在塑封外壳110的第一端面111靠近出线口131处设置固线结构103，利用固线结构103将线束300进行固定，使线束300得到有效固定，这样通过线夹400与固线结构103配合能够满足线束300密封和固定的需求，使线束300受到外力作用时大大降低线束300出现松动、拉脱的风险，提升了电机1000的可靠性。Considering that the wire clamp 400 has a certain flexibility, there is a problem of low bonding strength between the wire harness 300 and the wire clamp 400, and the wire harness 300 is prone to loosening and pulling off when subjected to external force. Therefore, the motor 1000 of the embodiment of the present application is provided with a fixed wire structure 103 at the first end face 111 of the plastic package shell 110 near the wire outlet 131, and the wire harness 300 is fixed by the fixed wire structure 103, so that the wire harness 300 is effectively fixed. In this way, the wire clamp 400 cooperates with the fixed wire structure 103 to meet the sealing and fixing requirements of the wire harness 300, so that the risk of loosening and pulling off of the wire harness 300 when subjected to external force is greatly reduced, thereby improving the reliability of the motor 1000.
参照图2和图3所示，在一些实施例中，固线结构103为形成于塑封外壳110的第一端面111的第一凸台140，第一凸台140上设有三个第一线槽141，三个第一线槽141间隔排列于第一凸台140的上端面，每个第一线槽141与线束300的单条导线匹配，也即是，通过三个第一线槽141可以同时固定三条导线。当然，第一线槽141的数量可根据线束300的导线数量进行设定，也可以设置四个或更多，不作具体限定。2 and 3, in some embodiments, the wire fixing structure 103 is a first boss 140 formed on the first end surface 111 of the plastic package housing 110, and three first wire grooves 141 are provided on the first boss 140. The three first wire grooves 141 are arranged at intervals on the upper end surface of the first boss 140, and each first wire groove 141 matches a single wire of the wire harness 300, that is, three wires can be fixed at the same time through the three first wire grooves 141. Of course, the number of the first wire grooves 141 can be set according to the number of wires of the wire harness 300, and four or more can also be set, without specific limitation.
需要说明的是，参照图3和图4所示，每个第一线槽141的槽体设有一个折弯段142，使第一线槽141整体呈L形状的槽体，第一线槽141的一端端口位于凸台靠近出线口131的侧壁，另一端端口位于第一凸台140的另一侧壁，图3所示实施例中，折弯段142的折弯角度为90°，可理解到，将导线对应放入第一线槽141后，导线会沿第一线槽141折弯形成弯曲线体，也就是说，第一线槽141的槽体并非直形槽，这样有利于增加导线与槽体之间的摩擦阻力，使导线不容易脱离第一线槽141。It should be noted that, referring to Figures 3 and 4, the groove body of each first wire groove 141 is provided with a bending section 142, so that the first wire groove 141 is an L-shaped groove body as a whole. One end port of the first wire groove 141 is located on the side wall of the boss close to the outlet 131, and the other end port is located on the other side wall of the first boss 140. In the embodiment shown in Figure 3, the bending angle of the bending section 142 is 90°. It can be understood that after the wire is placed in the first wire groove 141, the wire will be bent along the first wire groove 141 to form a curved wire body. In other words, the groove body of the first wire groove 141 is not a straight groove, which is conducive to increasing the friction resistance between the wire and the groove body, so that the wire is not easy to escape from the first wire groove 141.
值得指出的是，第一线槽141的折弯段142数量不限于一个，也可以设置两个或多个折弯段142，折弯角度也不限于90°，例如，通过折弯段142可形成U形状的槽体，或通过两个折弯段142配合形成S形状的槽体，折弯角度范围可以在90°至180°内，需要说明的是，当折弯形成180°时，导线形成两段相互平行的线体。可理解到，折弯段142的数量越多，折弯角度越大，导线与槽体之间的摩擦阻力越大，导线也难以脱离第一线槽141，每条导线固定在相应的第一线槽141后，能够使整个线束300得到更有效的固定，大大降低线束300出现松动、拉脱的风险。It is worth pointing out that the number of the bending sections 142 of the first wire groove 141 is not limited to one, and two or more bending sections 142 may be provided, and the bending angle is not limited to 90°. For example, a U-shaped groove body may be formed by the bending section 142, or an S-shaped groove body may be formed by the cooperation of two bending sections 142. The bending angle range may be between 90° and 180°. It should be noted that when the bending is formed at 180°, the wire forms two parallel wire bodies. It can be understood that the more the number of bending sections 142 and the larger the bending angle, the greater the friction resistance between the wire and the groove body, and the wire is difficult to detach from the first wire groove 141. After each wire is fixed in the corresponding first wire groove 141, the entire wire harness 300 can be more effectively fixed, greatly reducing the risk of the wire harness 300 becoming loose or pulled off.
继续参照图3所示，实施例中，每个第一线槽141的侧壁分别设有多个凸筋143，多个凸筋143沿线槽的长度方向间隔设置，具体可以是，多个凸筋143在相对两侧壁上交错分布，凸筋143的数量可根据槽体的长度进行设定，不作具体限定。可理解到，凸出的凸筋143能够与槽体内的导线抵接，使导线与第一线槽141产生过盈配合的装配结构，进一步增加导线的牢固性。Continuing to refer to FIG. 3 , in the embodiment, the side walls of each first wire slot 141 are respectively provided with a plurality of convex ribs 143, and the plurality of convex ribs 143 are arranged at intervals along the length direction of the wire slot. Specifically, the plurality of convex ribs 143 are staggeredly distributed on the opposite side walls, and the number of convex ribs 143 can be set according to the length of the slot body, and is not specifically limited. It can be understood that the protruding convex ribs 143 can abut against the wire in the slot body, so that the wire and the first wire slot 141 have an interference fit assembly structure, further increasing the firmness of the wire.
需要说明的是，凸筋143凸起的高度可根据导线的线径进行设定，避免凸筋143过高而对导线造成过度的挤压损伤。此外，实施例中第一线槽141的深度设置大于或等于1.5倍的导线的线径，能够进一步防止导线脱离第一线槽141，例如，第一线槽141的深度为导线的线径的3倍。It should be noted that the height of the convex rib 143 can be set according to the wire diameter of the wire to avoid excessive extrusion damage to the wire caused by the convex rib 143 being too high. In addition, in the embodiment, the depth of the first wire groove 141 is set to be greater than or equal to 1.5 times the wire diameter of the wire, which can further prevent the wire from escaping from the first wire groove 141. For example, the depth of the first wire groove 141 is 3 times the wire diameter of the wire.
以电源线的线束300为示例，线束300先固定在线夹400上，然后将各条导线对应固定到第一线槽141内，使线体折弯并通过凸筋143配合，达到过盈配合的目的，线束300中每条导线均得到固定，有效避免线束300出现松脱。Taking the wiring harness 300 of the power cord as an example, the wiring harness 300 is first fixed on the wire clamp 400, and then each wire is fixed to the first wire groove 141 accordingly, so that the wire body is bent and matched through the rib 143 to achieve the purpose of interference fit. Each wire in the wiring harness 300 is fixed, effectively preventing the wiring harness 300 from loosening.

Specifically, the wire fixing structure 103 is a second boss 150 formed on the first end surface 111 of the plastic package shell 110. The second boss 150 is provided with a second wire groove 151 and a fixing plate 160 covering the second wire groove 151. The fixing plate 160 can be used to compress the wire placed in the second wire groove 151, thereby playing a role in fixing the wire. Three second wire grooves 151 are provided on the second boss 150. The three second wire grooves 151 are arranged at intervals on the upper end surface of the second boss 150. Each second wire groove 151 matches a single wire, that is, three wires can be fixed at the same time through the three second wire grooves 151. Of course, the number of second wire grooves 151 can be set according to the number of wires in the wiring harness 300, and four or more can also be set without specific limitation.

The fixing plate 160 is provided with three protrusions 161 on the side facing the second boss 150. The three protrusions 161 correspond to the three second wire slots 151 one by one, and the number of protrusions 161 is set according to the number of second wire slots 151. In combination with FIG6 , it can be understood that after the wire is placed in the second wire slot 151, the fixing plate 160 is used to cover the second boss 150, and the protrusions 161 correspond to the wire located in the slot body, thereby playing the role of fixing the wire harness 300, enabling the entire wire harness 300 to be more effectively fixed, greatly reducing the risk of loosening and pulling off of the wire harness 300. It should be noted that the second wire slot 151 is arranged at an angle to facilitate the routing of the line, and the arrangement of the second wire slot 151 is not specifically limited.
继续参照图5所示，第二凸台150的上端面设有定位柱152，在固定板160的底面设有定位孔（附图未示出），通过定位柱152与定位孔配合对固定板160进行定位，使定位板能够实现快速装配。可理解到，在一些实施例中，可以在第二凸台150上设置定位孔，将定位柱152设置在固定板160，也能够达到配合定位的效果。Continuing to refer to FIG. 5 , a positioning column 152 is provided on the upper end surface of the second boss 150, and a positioning hole (not shown in the drawings) is provided on the bottom surface of the fixing plate 160. The fixing plate 160 is positioned by the positioning column 152 in cooperation with the positioning hole, so that the positioning plate can be quickly assembled. It can be understood that in some embodiments, a positioning hole can be provided on the second boss 150, and the positioning column 152 can be provided on the fixing plate 160, which can also achieve the effect of cooperative positioning.
需要说明的是，参照图6所示，实施例中固定板160采用塑料材质制作而成，利用端盖200将固定板160压紧在第二凸台150上，无需依靠额外的部件将固定板160进行固定，在端盖200装配完成后即可达到紧固固定板160的目的，并能够将导线压紧在第二线槽151内，结构设计更加合理，装配简便快捷。降低对线体产生损伤的风险。It should be noted that, as shown in FIG. 6 , the fixing plate 160 in the embodiment is made of plastic material, and the fixing plate 160 is pressed against the second boss 150 by the end cap 200 , and no additional components are required to fix the fixing plate 160 . After the end cap 200 is assembled, the fixing plate 160 can be fastened, and the wire can be pressed into the second wire slot 151 , so the structural design is more reasonable, and the assembly is simple and quick, which reduces the risk of damage to the wire body.
图7、图8和图9示出另一实施例的固线结构103，固线结构103为形成于塑封外壳110的第一端面111的固线柱170，固线柱170的数量为三根，三根固线柱170间隔排列在第一端面111靠近出线口131位置，可理解到，线束300在穿过出线口131后，直接将线束300缠绕三根固线柱170上，具体可以采用S形状等绕线方式依次缠绕三根固线柱170，通过线束300与固线柱170之间的摩擦，达到固定线束300的作用，有效避免线束300出现松脱。Figures 7, 8 and 9 show a wire fixing structure 103 of another embodiment. The wire fixing structure 103 is a wire fixing post 170 formed on the first end surface 111 of the plastic package shell 110. There are three wire fixing posts 170. The three wire fixing posts 170 are arranged at intervals on the first end surface 111 near the wire outlet 131. It can be understood that after the wire harness 300 passes through the wire outlet 131, the wire harness 300 is directly wound around the three wire fixing posts 170. Specifically, the three wire fixing posts 170 can be wound in sequence in an S-shaped winding method. The friction between the wire harness 300 and the wire fixing posts 170 can achieve the effect of fixing the wire harness 300, and effectively prevent the wire harness 300 from loosening.
需要说明的是，固线柱170的数量不限于三根，也可以设置两根固线柱170，将线束300依次缠绕在两根固线柱170上；也可以设置四个或更多的固线柱170，具体不作进一步限定。此外，固线柱170的高度大于或等于导线的线径的3倍，例如，固线柱170的高度可设置为5倍的导线的线径，使固线柱170具有足够的高度，可理解到，固线柱170的高度越大，线束300越不容易松脱，稳定性更佳。It should be noted that the number of the wire fixing posts 170 is not limited to three. Two wire fixing posts 170 may be provided, and the wire harness 300 may be wound around the two wire fixing posts 170 in sequence. Four or more wire fixing posts 170 may also be provided, and the specific number is not further limited. In addition, the height of the wire fixing post 170 is greater than or equal to 3 times the wire diameter of the wire. For example, the height of the wire fixing post 170 may be set to 5 times the wire diameter of the wire, so that the wire fixing post 170 has a sufficient height. It can be understood that the greater the height of the wire fixing post 170, the less likely the wire harness 300 is to loosen, and the better the stability.
本申请的实施例还提供一种电器设备（附图未示出），该电器设备可以是空调器等家用电器，电器设备采用上述实施例的电机1000作为驱动部件。The embodiments of the present application further provide an electrical device (not shown in the drawings), which may be a household appliance such as an air conditioner, and the electrical device uses the motor 1000 of the above embodiment as a driving component.

The wire clamp 400 is made of silicone or rubber material. The wire clamp 400 can clamp the wire passing through the wire outlet 131. The wire clamp 400 is squeezed to deform and fit tightly with the inner wall of the wire outlet 131 to form a sealing structure, thereby achieving an effective seal between the wire clamp 400 and the plastic housing 110. The wire clamp 400 can not only fix the wiring harness 300, but also play a sealing role, thereby effectively improving the sealing of the motor 1000, reducing the phenomenon of water ingress into the motor 1000, and improving the operating reliability of the motor 1000. In addition, by setting a wire fixing structure 103 near the wire outlet 131 of the plastic shell 110, the wire fixing structure 103 is used to fix the wire harness 300, so that the wire harness 300 is effectively fixed. In this way, the wire clamp 400 cooperates with the wire fixing structure 103 to meet the sealing and fixing requirements of the wire harness 300, so that the risk of loosening or pulling off of the wire harness 300 when the wire harness 300 is subjected to external force is greatly reduced.
