Description

[0002] The alternating current motor is a device for converting alternating current into mechanical energy, which is widely used in industry and daily life. There are two common types: asynchronous motor and synchronous motor. Each type has its own unique working principle and characteristics. The asynchronous motor has a simple structure and low cost. It relies on electromagnetic induction principle. The rotor speed is slightly lower than the rotating magnetic field speed. The rotating magnetic field is generated by the stator winding, which makes the rotor rotate. It is widely used in fan, water pump and other equipment.

[0003] The alternating current motor outgoing line binding structure is mainly used to fix the outgoing lines together with insulating materials (such as binding tape, etc.) to prevent the outgoing lines from loosening and shifting.

When fixed with binding wires, the inside of the silicone tube and the surface of the power line are smooth. If the binding wire is too tight, it may cause the enameled wire to break. If the binding wire is too loose, it may cause the outgoing line to fall off, causing the motor to break, not to run, and short circuit fire, etc. serious safety problems, resulting in motor breakage, even due to poor contact of the line to produce electric spark, there is a risk of short circuit fire, which greatly threatens the safety of personnel and property, brings serious safety hazards and adverse consequences.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Reference Figures 1 to 2 This utility model provides an embodiment of an AC motor lead wire binding structure, including a stator core 1, which is the basic component of the motor and serves to support and fix the copper wire windings 2. Multiple copper wire windings 2 are arranged inside the stator core 1. The copper wire windings 2 are the part of the motor that realizes the mutual conversion of electrical energy and mechanical energy. A protector 3 is fixedly connected to the top of the outer side of one of the copper wire windings 2. The protector 3 can monitor the current during the operation of the motor and cut off the current in time when the current is too large. A power line 7 is detachably connected to one end of the copper wire winding 2 away from the stator core 1. The power line 7 and one end of the copper wire winding 2 are connected by welding. After welding, insulating tape is wrapped to ensure that the current can be smoothly transmitted from the power line 7 to the copper wire winding 2.

[0021] A silicone tube 4 is sleeved on the outer end of the copper wire winding 2 away from the stator core 1. The silicone tube 4 effectively prevents creepage caused by electric field concentration at the end of the copper wire winding 2 and avoids short circuit faults between the winding and surrounding metal parts. Multiple binding wires 5 are fixedly connected in a ring on the top of the stator core 1. The binding wires 5 wrap around and fix the silicone tube 4 to prevent the silicone tube 4 from shifting due to vibration. The inner wall of the binding wire 5 is in contact with the outer side of the silicone tube 4. The binding wires 5 can fix the silicone tube 4 and the internal power line 7. A polyester Mylar tape 6 is provided on the outer side of the power line 7 away from the copper wire winding 2. The polyester Mylar tape 6 wraps around the end of the power line 7 away from the copper wire winding 2 to prevent the power line 7 from falling out of the silicone tube 4.

[0022] The stator core 1 has a wire outlet groove 8 inside, which facilitates the entry and exit of the power cable 7. The inner wall of the wire outlet groove 8 is in contact with the outer side of the power cable 7 away from the copper wire winding 2, which can limit and guide the power cable 7. After the power cable 7 is fixed by the polyester Mylar tape 6, it is prevented from falling out of the wire outlet groove 8 by one of the binding wires 5. The power cable 7 is fixed by wrapping the polyester Mylar tape 6, and the power cable 7 after being fixed by the polyester Mylar tape 6 is fixed again by one of the binding wires 5. The double fixing method effectively prevents the power cable 7 from falling out of the wire outlet groove 8 during the operation of the motor due to vibration, rotation or other external forces.

[0023] Working principle: The power cord 7 is soldered to the enameled wire in the copper wire winding 2. After the soldering is completed, the solder joint is wrapped with insulating tape in multiple layers to prevent the solder joint from being exposed to the air and to prevent oxidation, moisture and other factors from affecting the stability of the electrical connection. Then, it is put into the silicone tube 4. The silicone tube 4 is soft and has excellent insulation performance, which can effectively disperse the electric field and avoid excessive concentration of the electric field at the end, which will cause creepage. This greatly enhances the insulation protection capability, prevents electric field creepage, and improves the insulation protection. The silicone tube 4 is fixed to the solder joint with the binding wire 5, which initially stabilizes the lead wire. At the same time, the silicone tube 4 is arranged in a ring.

[0024] After the silicone tubes 4 are bundled and arranged, up to the cable outlet 8, use polyester Mylar tape 6 to wrap one side of the power cord 7 two or three times. The adhesiveness of the polyester Mylar tape 6 can tightly bind the power cord 7 and prevent it from slipping out of the silicone tubes 4. Then use another binding wire 5 to fix it. With the tape wrapping and fixing, the power cord 7 will not fall out of the silicone tubes 4, making the overall structure stable and preventing displacement and falling off.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
