Description

[0002] An electric motor mainly consists of two parts: the stator and the rotor, and may also include other accessories. The stator is part of the motor's magnetic circuit, housing the stator windings and generating a rotating magnetic field when three-phase alternating current is applied. For DC motors, the stator also includes the main magnetic poles and brush assembly. The rotor is the other part of the motor's magnetic circuit, housing the rotor windings in the core slots. Through a commutator and sliding contact with the brushes, it receives direct current from the outside, generating electromagnetic torque to rotate the motor. In AC motors, the rotor windings induce current in the rotating magnetic field generated by the stator, interacting with the magnetic field to produce electromagnetic torque.

[0003] After the stator winding is completed, the stator winding leads need to be connected to the controller, power supply, etc. In some commercially available motors, the stator winding leads are connected to the external power supply, controller, etc., via wires or conductive plates. During motor assembly, workers typically need to additionally use screws to secure the wires or conductive plates to achieve conductivity. This design requires workers to spend considerable time connecting the wires, impacting assembly efficiency.

[0004] For example, Chinese patent application CN201910635480.1 discloses a motor wiring structure, specifically stating that "the support frame is divided into a first support frame and a second support frame; the conductive sheet includes a conductive substrate and several conductive heads; the conductive substrate is wrapped by the first support frame; the end of the insulating frame has a groove; the first support frame has fixed pins that are inserted into the grooves at the end of the insulating frame; the first support frame also has fixed protrusions; the second support frame has through holes that are fixed to the first support frame; the second support frame has conductor posts with conductor holes; the tail ends of several windings are connected to the conductive heads of the conductive sheet; and the head ends of several windings are led out of the motor through the conductor holes in the conductor posts." In this design, the conductive sheet and windings are fixedly connected by screws, requiring workers to spend considerable time wiring, thus affecting assembly efficiency. Utility Model Content

[0030] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0031] Example 1

[0032] Please refer to Figures 1 to 5 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is a connector assembly structure.

[0033] In this design, the lead-out end of the stator winding 114 is wound around the first terminal 136, and the second terminal 24 is disposed inside the first housing 21. The first housing 21 is assembled on the base 137, and the first terminal 136 and the second terminal 24 are soldered together. The wire 213 can be directly inserted into the connector 20 to lead out the wiring of the stator winding 114. This design facilitates wiring and makes assembly more convenient.

[0034] This application provides a stator for easy wiring, including a connector 20 and a frame 10; a stator winding 114 is disposed on the frame 10; the connector 20 includes a base 137, a first housing 21, a first terminal 136, and a second terminal 24; the base 137 is formed on the frame 10; the first terminal 136 is disposed on the base 137; the second terminal 24 is embedded in the first housing 21; the first housing 21 is fastened to the base 137; the terminal of the second terminal 24 is exposed on the first housing 21; a wire 213 is inserted into the connector 20 and is conductive to the terminal of the second terminal 24; the lead end of the stator winding 114 is connected to the first terminal 136; the pin end of the second terminal 24 extends from the first housing 21 and is connected to the first terminal 136. The frame 10 is manufactured using injection molding. The base 137 is directly injection molded onto the frame 10, and the first terminal 136 can be directly injection molded onto the frame 10 or assembled by a plug-in method. The first housing 21 has a wiring hole 22, through which the core of the wire 213 can be inserted. The core is conductive to the second terminal 24. This design makes assembly very convenient. After the winding machine finishes winding, the enameled wire is stripped, and then the exposed enameled wire is wound around the first terminal 136. The second terminal 24 is bent and assembled into the first housing 21 by press fitting. When the first housing 21 is assembled on the base 137, the first terminal 136 passes through the second terminal 24, and then the first terminal 136 and the second terminal 24 are welded together to ensure contact quality. Preferably, a wire clamp is provided at the wiring hole 22; the wire clamp clamps the wire 213 to prevent the wire 213 from falling off. The wire clamp can be a butterfly clamp, elastic clamp, spring clip, etc. The wire clamp can be set on the first housing 21 by screws or glue. In this embodiment, each connector is correspondingly connected to the corresponding wire 213.

[0035] Preferably, the first housing 21 is provided with a wiring hole 22, and the wiring end of the second terminal 24 is bent to form a clamping opening 29, into which the wire 213 is inserted; the welding end of the second terminal 24 has a forked portion 26; the first terminal 136 passes through the forked portion 26. The size of the wiring hole 22 is adapted to the wire 213. The second terminal 24 is elastic, and the clamping opening 29 can be formed by stamping. When the wire core of the wire 213 is inserted into the clamping opening 29, the clamping opening 29 can clamp the wire core. The clamping opening 29 can be V-shaped or straight. The forked portion 26 is formed by a process, and the forked portion 26 can be annular or forked. This design can ensure the conductivity between the first terminal 136 and the second terminal 24, and the contact area between the first terminal 136 and the second terminal 24 is larger, resulting in a stronger weld. The bending of the end of the second terminal 24 is more conducive to layout, making it easier for the first terminal 136 to pass through the second terminal 24. The second terminal 24 is also bent in the middle, a design that allows it to be secured within the first housing 21, preventing it from becoming loose. The first set of wires 213 is connected to the gear switch, and the second set is connected to the starting capacitor. Wires 213 have multiple cores, with the first wire 213 connected to the stator winding 114 via the first connector 20. Wires 213 extend from the wiring hole 22 and are then soldered to the terminal of the second terminal 24. This structure conceals the soldering point, providing better insulation and safety.

[0036] Preferably, a terminal groove 210 is provided inside the first housing 21; a limiting strip 211 is formed on the inner wall of the terminal groove 210; the bent second terminal 24 is embedded in the terminal groove 210, and the limiting strip 211 presses against the side edge of the second terminal 24. A limiting part 212 is formed by the protrusion of the side of the second terminal 24. When the second terminal 24 is pressed into the terminal groove 210, the limiting strip 211 presses against the limiting part 212 on the side edge of the second terminal 24. This design allows the second terminal 24 to be firmly stuck in the first housing 21 and not to come loose.

[0037] Preferably, a mounting groove 133 is formed on the base 137; a first terminal block 135 is disposed in the mounting groove 133, and the first terminal 136 is inserted into the first terminal block 135; a first limiting edge 134 is provided on the mounting groove 133; a second limiting edge 23 is provided on the side of the first shell 21; the bottom of the first shell 21 is embedded in the mounting groove 133; the first terminal block 135 supports the first shell; the first limiting edge 134 presses against the second limiting edge 23. The first terminal block 135 is injection molded in the mounting groove 133, and the first terminal 136 can be directly inserted into the first terminal block 135. This design makes the assembly of the first terminal 136 very convenient and accurate. Of course, the first terminal 136 can also be injection molded together with the first terminal block 135, which provides higher structural strength. The pins of the second terminal 24 are soldered to the first terminal 136. A stator winding 114 is wound on the frame 10 by a winding machine. The first housing 21 is pushed into the mounting groove 133. At this time, the first limiting edge 134 presses against the second limiting edge 23, fixing the first housing 21 within the mounting groove 133. Simultaneously, the pins of the first terminal 136 and the second terminal 24 come into contact with each other. After winding is completed, the robotic arm welds the first terminal 136 and the second terminal 24 together. This design eliminates the need for manual wiring, resulting in higher production efficiency. When the connector 20 needs maintenance, the first housing 21 can simply be pulled out of the mounting groove 133, making the assembly and disassembly of the connector 20 very convenient. The first terminal holder 135 supports the first housing 21. The first terminal holder 135 is injection molded within the mounting groove 133. The first terminal 136 can be installed in the first terminal holder 135 via insertion or injection molding, resulting in higher structural robustness.

[0038] Preferably, the groove wall of the mounting groove 133 forms a fitting opening with the first limiting edge 134, and the second limiting edge 23 is fitted into this fitting opening. Alternatively, the first limiting edge 134 can extend from the opening of the mounting groove 133, pressing against the second limiting edge 23. Specifically, this embodiment has two mounting grooves 133. In the first mounting groove 133, the fitting opening is formed between the groove wall of the mounting groove 133 and the first limiting edge 134. In the second mounting groove 133, the first limiting edge 134 extends from the opening of the mounting groove 133, pressing against the second limiting edge 23. Both designs can secure the first connector 20, preventing it from loosening and facilitating assembly.

[0039] Preferably, the frame 10 includes an upper wire frame 110 and a lower wire frame 130; the upper wire frame 110 and the lower wire frame 130 are closed on the inner core 120; a plurality of first winding plates 111 are formed on the upper wire frame 110; a plurality of second winding plates 131 are formed on the lower wire frame 130, and the first winding plates 111 and the second winding plates 131 are closed to form a winding post 113; a first limiting post 121 on the inner core 120 passes through the winding post 113; a first fitting groove 141 in the outer core 140 is fitted together with the first limiting post 121. The structure of the first fitting groove 141 and the first limiting post 121 can be dovetail-shaped or wedge-shaped. When the upper winding frame 110 and the lower winding frame 130 are embedded in the inner core 120, the upper winding frame 110 and the lower winding frame 130 are closed together. After the first winding plate 111 and the second winding plate 131 are closed, a winding post 113 is formed, and the stator winding 114 is wound on the winding post 113. The first fitting groove 141 in the outer core 140 is fitted together with the first limiting post 121, so that the upper winding frame 110, the inner core 120, the lower winding frame 130, and the outer core 140 can be assembled together without loosening. The mounting groove 133 can be set on the upper winding frame 110 or the lower winding frame 130. Before winding, the upper wire frame 110, inner iron core 120, and lower wire frame 130 are assembled together. After winding is completed, the winding machine winds the stator winding pins 25 onto the first terminal. Then, the outer iron core 140 is pressed onto the first limiting post 121 of the inner iron core 120, so that the upper wire frame 110, inner iron core 120, lower wire frame 130, and outer iron core 140 are assembled into a whole.

[0040] Preferably, the first winding plate 111 has a first limiting plate 112 at its end; the second winding plate 131 has a second limiting plate 132 at its end; the first limiting plate 112 and the second limiting plate 132 overlap together. The overlap of the first limiting plate 112 and the second limiting plate 132 can position the stator winding 114, facilitating the winding machine to wind the wire on the winding post 113.

[0041] Preferably, in this embodiment, there are two connectors 20. The first connector 20 is connected to the gear switch; the second connector 20 is connected to the starting capacitor 27. The two connectors 20 work together to control the motor and facilitate motor starting. Both connectors are connected to the stator windings. A fuse is connected between the first and second connectors to improve motor safety.

[0042] Example 2

[0043] Example 2 includes the stator with easy wiring as in Example 1; the same parts will not be described again. Please refer to [link / reference needed] for details. Figures 6-8The oscillating motor shown includes a stator for easy wiring; a rotor 30; a front housing 31; a rear housing 32; a frame 10 with a stator winding 114; the rotor 30 passing through the frame 10; the front housing 31 fixed to the front of the frame 10, and the rear housing 32 fixed to the back of the frame 10; a first positioning plate 33 on the front housing 31 and a second positioning plate 34 on the rear housing 32 pressing against the outer periphery of the frame 10; the first end of the rotor 30 protruding from the front housing 31; and the second end of the rotor 30 protruding from the rear housing 32 and entering the oscillating mechanism 35. The connector 20 can be clamped by the front housing 31 and the rear housing 32, preventing the connector 20 from loosening and improving its stability. The stator is the stationary part of the motor, mainly composed of a stator core and a stator winding 114. The stator core is part of the motor's magnetic circuit and is used to house the stator winding 114. The stator winding 114 is supplied with three-phase alternating current, generating a rotating magnetic field. For a DC motor, the stator also includes the main magnetic poles and brush assembly. The rotor 30 is the rotating part of the motor, mainly composed of the rotor 30 core and rotor 30 windings. The rotor 30 core is another part of the motor's magnetic circuit. The rotor 30 windings slide in contact with the brushes through the commutator in the DC motor, receiving DC current from the outside and generating electromagnetic torque to rotate the motor. After the internal components such as the upper frame 110, inner core 120, lower frame 130, outer core 140, and rotor 30 are assembled, screws pass through the front housing 31, rear housing 32, and outer core 140 to assemble the frame 10, front housing 31, and rear housing 32 together. The first positioning plate 33 and the second positioning plate 34 cooperate to accurately position the installation positions of the front housing 31 and rear housing 32, ensuring good assembly precision. The oscillating mechanism 35 can be one of the following: crank-rocker mechanism, worm gear mechanism, single-link mechanism, four-link mechanism, cam mechanism, or gear transmission mechanism. A four-bar linkage consists of four components connected by hinges (revolute joints). The stationary link is called the frame, the link connected to the frame via revolute joints is called the connecting link, and the link not connected to the frame is called the connecting rod. Depending on whether the two connecting rods are cranks or rockers, four-bar linkages can be classified as double-crank mechanisms, crank-rocker mechanisms, and double-rocker mechanisms. A crank-rocker mechanism typically includes a crank and a rocker; the crank is the driving member and rotates at a constant speed, while the rocker is the driven member and oscillates back and forth at varying speeds. A worm gear mechanism transmits power and motion through the meshing of a worm wheel and a worm, featuring a large transmission ratio and self-locking properties. In electric fans, worm gear mechanisms are commonly used to provide stable transmission force, enabling the fan to oscillate smoothly. In this embodiment, the oscillation mechanism 35 is a worm gear mechanism. Gear transmission mechanisms transmit power and motion through the meshing of two gear teeth, featuring compact structure, high efficiency, and long service life.

[0044] In summary, the key design feature of this utility model is that the lead-out end of the stator winding 114 is wound around the first terminal 136, and the pin end of the second terminal 24 passes through the first housing 21 and is soldered to the first terminal 136. When connecting the wire 213, it is only necessary to insert the end of the wire 213 into the wiring hole 22 on the first housing 21 to make the connector 20 and the wire 213 conduct. This design makes wiring convenient and helps to improve the efficiency of motor assembly.
