Description

Technical Field

[0001] The invention relates to the technical field of aluminum enameled wires, in particular to an aluminum enameled wire for an air-conditioning compressor with an anti-oxidation coating. Background Art

[0002] Enameled aluminum wire is a main type of winding wire, consisting of a conductor and an insulating layer. The bare wire is annealed and softened, then painted and baked multiple times. Aluminum enameled wire is a material that plays a key role in air-conditioning compressors. During operation, air-conditioning compressors are in a certain temperature and humidity environment and may be exposed to air. Without an anti-oxidation coating, the aluminum conductor of the aluminum enameled wire is easily oxidized with oxygen in the air to form aluminum oxide on the surface. Aluminum oxide is an insulating substance that increases the resistance of the enameled wire, reduces its electrical conductivity, and affects the normal operation of the air-conditioning compressor. The anti-oxidation coating can effectively isolate the aluminum conductor from oxygen, prevent the occurrence of oxidation reactions, and ensure the long-term stability of the electrical conductivity of the aluminum conductor.

[0003] In air-conditioning compressors, aluminum enameled wire is used as the winding of the motor. It can form a specific coil structure by winding. The shape of the aluminum enameled wire is generally cylindrical. However, the cylindrical enameled wire is only combined by friction when winding. When affected by external vibration, temperature change and other factors, relative sliding and dislocation are prone to occur, thus affecting the stability and reliability of the circuit.

[0004] In addition, when the aluminum enameled wires slide relative to each other, the contact between the enameled wires becomes loose, and air and moisture are easily retained in the gaps between the enameled wires, which increases the chance of the anti-oxidation layer coming into contact with external corrosive factors, making the anti-oxidation layer more susceptible to erosion, thereby reducing its anti-oxidation effect. In view of this, we propose an air-conditioning compressor aluminum enameled wire with an anti-oxidation coating. Summary of the invention

[0005] The object of the present invention is to provide an air-conditioning compressor aluminum enameled wire with an anti-oxidation coating to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides an air-conditioning compressor aluminum enameled wire with an anti-oxidation coating, comprising an aluminum core body, wherein two adjacent layers of aluminum core bodies wound into a coil are defined as a No. 1 aluminum wire and a No. 2 aluminum wire, and a protruding clamping structure and a concave receiving structure are provided on the aluminum core body. When the aluminum core body is wound, the protruding clamping structure of the No. 1 aluminum wire is adapted to be inserted into the concave part of the concave receiving structure of the No. 2 aluminum wire, so that the aluminum core bodies on the adjacent two sides are clamped and fixed;

[0007] The protruding clamping structure is provided with a fastening mechanism, and the protruding clamping structure is limited by the deformation force of the fastening mechanism.

[0008] As a further improvement of the technical solution, the protruding clamping structure includes a plurality of protrusions fixedly connected to the outer wall of the aluminum core body, and the protruding ends of the protrusions are trapezoidal.

[0009] As a further improvement of the technical solution, the recessed receiving structure includes a groove formed between two of the protrusions, and the interior of the groove is snap-fitted with the protrusion.

[0010] As a further improvement of the technical solution, the aluminum core body and the outer wall of the protrusion are both wrapped with an anti-oxidation layer, and the anti-oxidation layer is a silicone resin paint layer.

[0011] As a further improvement of the technical solution, the outer wall of the anti-oxidation layer is wrapped with an insulating layer, and the insulating layer is a polyester resin paint layer.

[0012] As a further improvement of the present technical solution, the fastening mechanism includes a No. 1 metal sheet fixedly connected to both sides of the inner wall of the groove insulating layer on the No. 1 aluminum wire, and the insulating layer at the protruding end of the bump of the No. 2 aluminum wire is fixedly connected to two No. 2 metal sheets, and the two No. 2 metal sheets are symmetrically arranged at both ends of the insulating layer.

[0013] As a further improvement of the technical solution, a pad is fixedly connected to the outer wall of the smooth area of ​​the aluminum core body, and the diameter of the pad is smaller than the diameter of the protrusion.

[0014] As a further improvement of the technical solution, the pad and the protrusion are both made of aluminum alloy material, and the first metal sheet and the second metal sheet are made of beryllium bronze material.

[0015] As a further improvement of the technical solution, the protruding clamping structure, the recessed receiving structure and the fastening mechanism are provided in multiple groups and are evenly arranged on the outer wall of the aluminum core body.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the aluminum enameled wire for air-conditioning compressor with an anti-oxidation coating, the protrusion on the No. 2 aluminum wire is aligned with the groove of the No. 1 aluminum wire, and then the No. 2 aluminum wire is squeezed. Under the action of external force, the protrusion on the No. 2 aluminum wire is clamped into the groove of the No. 1 aluminum wire, so that the winding of the aluminum core body is tighter, and the No. 1 aluminum wire and the No. 2 aluminum wire in the folded and fitted area of ​​the aluminum core body during winding can be tightly combined and will not easily loosen or spread out, which can effectively prevent the No. 1 aluminum wire and the No. 2 aluminum wire from sliding relative to each other.

[0018] 2. In the air-conditioning compressor aluminum enameled wire with an antioxidant coating, the folding area of ​​the aluminum core body is tightly fitted by clamping the protruding clamping structure and the recessed receiving structure, which can effectively prevent corrosive factors such as air and moisture from entering the gap between the folding areas of the aluminum core body, reducing the chance of the antioxidant layer contacting external corrosive factors, thereby better protecting the antioxidant layer and making it less susceptible to erosion, thereby improving the anti-oxidation effect of the aluminum core body.

[0019] 3. In the air-conditioning compressor aluminum enameled wire with an anti-oxidation coating, when the bump on the No. 2 aluminum wire is clamped into the groove on the No. 1 aluminum wire, the No. 1 metal sheet and the No. 2 metal sheet move elastically, so that the No. 1 metal sheet and the No. 2 metal sheet can clamp the bump and press against the inner wall of the groove respectively. The additional clamping force makes the bump on the No. 2 aluminum wire more stable in the groove on the No. 1 aluminum wire, and is not easy to loosen or fall out, thereby further improving the stability of the connection between the two bumps and the groove.

[0034] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] See also Figure 1-Figure 9 As shown, the present embodiment provides an air-conditioning compressor aluminum enameled wire with an anti-oxidation coating, including an aluminum core body 100, and the adjacent two layers of the aluminum core body 100 wound into a coil are defined as a No. 1 aluminum wire and a No. 2 aluminum wire, and a protruding clamping structure 200 and a recessed receiving structure 300 are provided on the aluminum core body 100. When the aluminum core body 100 is wound, the protruding clamping structure 200 of the No. 1 aluminum wire is adapted to be inserted into the recessed part of the recessed receiving structure 300 of the No. 2 aluminum wire, so that the aluminum core bodies 100 on the adjacent two sides are clamped and fixed, and the protruding block 210 on the No. 2 aluminum wire is aligned with the groove 310 of the No. 1 aluminum wire where it is in contact with it, and the protruding clamping structure 200 and the recessed receiving structure 300 are provided, so that the aluminum core body In the folding area of ​​the body 100, the recessed receiving structure 300 on the No. 1 aluminum wire can be clamped with the protruding clamping structure 200 on the No. 2 aluminum wire, so that the No. 1 aluminum wire and the No. 2 aluminum wire can be closely fitted, so as to avoid relative sliding and looseness between the No. 1 aluminum wire and the No. 2 aluminum wire when the aluminum core body 100 is wound. A fastening mechanism 400 is provided on the protruding clamping structure 200, and the protruding clamping structure 200 is limited by the deformation force of the fastening mechanism 400. When the protruding clamping structure 200 is clamped with the recessed receiving structure 300, the fastening mechanism 400 is driven to move elastically, and the protruding end of the protruding clamping structure 200 is fixed, thereby improving the stability of the connection between the protruding clamping structure 200 and the recessed receiving structure 300.

[0036] In the existing air-conditioning compressor, aluminum enameled wire is used as the winding of the motor, and a specific coil structure can be formed by winding. The shape of the aluminum enameled wire is generally cylindrical. However, the cylindrical enameled wire is only combined by friction when winding. When it is affected by external force vibration, temperature change and other factors, it is easy to slide and dislocate relative to each other, thereby affecting the stability and reliability of the circuit; therefore, a protruding clamping structure 200 and a recessed receiving structure 300 are provided, so that when the aluminum core body 100 is wound, the recessed receiving structure 300 on the No. 1 aluminum wire in the folding and bonding area of ​​the aluminum core body 100 can be clamped with the protruding clamping structure 200 on the No. 2 aluminum wire, so that the No. 1 aluminum wire and the No. 2 aluminum wire in the folding and bonding area of ​​the aluminum core body 100 can be tightly combined and will not easily loosen or spread out. Compared with the cylindrical aluminum enameled wire that is only wound by friction, this clamping structure provides a more reliable connection, and can effectively prevent relative sliding between the aluminum core bodies 100 when they are pulled by external forces, vibrations, etc.;

[0037] In addition, when the aluminum enameled wires slide relative to each other, the contact between the enameled wires becomes loose, and air and moisture are easily retained in the gaps between the enameled wires, which increases the chance of the anti-oxidation layer contacting with external corrosive factors, making the anti-oxidation layer more susceptible to erosion, thereby reducing its anti-oxidation effect; therefore, when the aluminum core body 100 is pulled by external force, the clamping method between the protruding clamping structure 200 and the recessed receiving structure 300 makes the folding area of ​​the aluminum core body 100 fit more closely, which can effectively prevent corrosive factors such as air and moisture from entering the gaps between the aluminum core bodies 100. Compared with the situation where the folding area of ​​the aluminum core body 100 has loose contact due to relative sliding, this clamping method greatly reduces the chance of the aluminum core body 100 contacting with external corrosive factors, thereby better protecting the aluminum core body 100, making it less susceptible to erosion, and significantly enhancing the anti-oxidation effect of the aluminum core body 100;

[0038] Furthermore, in order to prevent the protruding clamping structure 200 on the No. 2 aluminum wire from falling out of the recessed receiving structure 300 on the No. 1 aluminum wire when the aluminum core body 100 is pulled, a fastening mechanism 400 is provided. When the protruding clamping structure 200 and the recessed receiving structure 300 are clamped, the fastening mechanism 400 is driven to undergo elastic deformation, so that the fastening mechanism 400 generates a reaction force. The additional force generated can clamp the protruding end of the protruding clamping structure 200. This additional force makes the clamping between the protruding clamping structure 200 and the recessed receiving structure 300 more secure, effectively preventing loosening or falling out due to external force during use, and greatly improving the stability of the connection.

[0039] The aluminum core body 100 is made more stable during winding. Figure 4-Figure 6As shown, the specific structure of the protruding clip-on structure 200 is further disclosed. The protruding clip-on structure 200 includes a plurality of protrusions 210 fixedly connected to the outer wall of the aluminum core body 100. The protruding ends of the protrusions 210 are trapezoidal. When the trapezoidal protruding ends are subjected to force, their inclined sides can disperse the force to a larger area, making the stress distribution more uniform, reducing local stress concentration, and reducing the risk of damage to the protrusions 210 due to excessive stress. When winding, the protrusions 210 are inserted into the recessed portion of the recessed receiving structure 300, thereby making the connection between the enameled wires tighter and more stable.

[0040] Considering the stability of the bump 210 during insertion, Figure 4-Figure 6 As shown, the specific structure of the recessed receiving structure 300 is further disclosed. The recessed receiving structure 300 includes a groove 310 formed between two protrusions 210. The interior of the groove 310 is snap-fitted with the protrusion 210. When the aluminum core body 100 is wound, the two folded areas of the aluminum core body 100 are fitted together, and the protrusion 210 on the No. 2 aluminum wire is aligned with the groove 310 of the No. 1 aluminum wire where it fits. Then, the No. 2 aluminum wire is squeezed. Under the action of external force, the protrusion 210 on the No. 2 aluminum wire can be snapped into the groove 310 of the No. 1 aluminum wire, so that the winding of the aluminum core body 100 is more tightly combined and not easy to loosen or spread out.

[0041] Considering that the aluminum core body 100 needs to improve its anti-oxidation performance when in use, such as Figure 4 and Figure 7 and Figure 8 As shown, the outer walls of the aluminum core body 100 and the bump 210 are both wrapped with an anti-oxidation layer 101, and the anti-oxidation layer 101 is a silicone resin paint layer. The silicone resin paint layer can form a tight protective film on the surface of the aluminum core body 100 and the bump 210, blocking oxygen and water vapor in the air from direct contact with the aluminum material, thereby greatly slowing down the occurrence of oxidation reaction, and the silicone resin paint layer has a certain hardness and wear resistance, which can protect the aluminum core body 100 and the bump 210 to better resist external wear in daily use, ensuring that the anti-oxidation layer 101 always covers the surface of the aluminum material.

[0042] In order to ensure the safety of the aluminum core body 100 when in use, Figure 4 and Figure 7 and Figure 8 As shown, the outer wall of the anti-oxidation layer 101 is wrapped with an insulating layer 102, and the insulating layer 102 is a polyester resin paint layer. The polyester resin paint has good insulation properties and can effectively prevent the conduction of current between the aluminum core body 100 and other conductive objects, thereby avoiding the risk of leakage and short circuit.

[0043] In order to enhance the stability of the connection between the protruding snap-fit ​​structure 200 and the recessed receiving structure 300, as shown in FIG. Figure 5 and Figure 6 As shown, the specific structure of the fastening mechanism 400 is further disclosed. The fastening mechanism 400 includes a No. 1 metal sheet 410 fixedly connected to both sides of the inner wall of the insulating layer 102 of the groove 310 on the No. 1 aluminum wire, and two No. 2 metal sheets 420 are fixedly connected to the insulating layer 102 at the protruding end of the protrusion 210 of the No. 2 aluminum wire, and the two No. 2 metal sheets 420 are symmetrically arranged at both ends of the insulating layer 102. When the protrusion 210 on the No. 2 aluminum wire is clamped into the groove 310 on the No. 1 aluminum wire, the protrusion 210 on the No. 2 aluminum wire squeezes the No. 1 metal sheet 410, and the No. 1 metal sheet 410 is squeezed and deformed. The reaction force of the No. 1 metal sheet 410 is applied to the outer wall of the protrusion 210 on the No. 2 aluminum wire, so that the No. 1 metal sheet 410 can be tightly fastened. By clamping the bump 210 on the No. 2 aluminum wire, the extra clamping force makes the bump 210 on the No. 2 aluminum wire more stable in the groove 310 on the No. 1 aluminum wire, and it is not easy to loosen or fall out. When the bump 210 on the No. 2 aluminum wire moves, it drives the No. 2 metal sheet 420 to move and squeeze and clamp with the inner wall of the groove 310 on the No. 1 aluminum wire. The elastic force of the No. 2 metal sheet 420 further improves the stability of the connection between the bump 210 on the No. 2 aluminum wire and the groove 310 on the No. 1 aluminum wire; and the thickness of the No. 1 metal sheet 410 and the No. 2 metal sheet 420 is moderate, which can ensure that the No. 1 metal sheet 410 and the No. 2 metal sheet 420 can produce sufficient elastic deformation when squeezed, and have sufficient strength to withstand the squeezing force.

[0044] Considering that the smooth area of ​​the aluminum core body 100 is not provided with the protruding clamping structure 200 and the recessed receiving structure 300, when the protruding clamping structure 200 and the recessed receiving structure 300 are clamped, the smooth area of ​​the aluminum core body 100 also needs to be closely fitted, such as Figure 4 and Fig. 9 As shown, a cushion block 500 is fixedly connected to the outer wall of the smooth area of ​​the aluminum core body 100, and the diameter of the cushion block 500 is smaller than the diameter of the protrusion 210. When the two end areas of the aluminum core body 100 are wound and bonded, the protruding clamping structure 200 and the recessed receiving structure 300 of the clamping area are clamped and bonded. The cushion block 500 is provided to ensure that when the protruding clamping structure 200 and the recessed receiving structure 300 are clamped, the smooth area of ​​the aluminum core body 100 can be tightly bonded, and the air can be effectively prevented from entering the smooth area of ​​the aluminum core body 100, which greatly reduces the aluminum core body. 100 reduces the risk of oxidation due to contact with air, and the pad 500 can play a supporting and balancing role, so that when the aluminum core body 100 is subjected to external force, the pad 500 can share the external force with the protruding clamping structure 200 and the recessed receiving structure 300, thereby reducing the deformation and damage risks of the aluminum core body 100 at the clamping part and improving the stability of the entire structure. The outer wall of the pad 500 is also coated with an anti-oxidation layer 101 and an insulating layer 102 to prevent the pad 500 from oxidation and rusting, and to prevent current from being conducted between the pad 500 and other components.

[0045] In order to prevent the fastening mechanism 400 from breaking when the protruding engaging structure 200 and the recessed receiving structure 300 are engaged, Figure 6 and Fig. 9 As shown, the pad 500 and the protrusion 210 are both made of aluminum alloy material. The aluminum alloy has good electrical conductivity, which matches the electrical conductivity of the aluminum core body 100, and can effectively conduct current to ensure that the electrical connection between the enameled wires is stable and reliable. Good electrical conductivity can reduce energy loss and improve circuit efficiency. In addition, the aluminum alloy has high strength and can withstand the pressure and friction generated during the winding process. When the protrusion 210 is inserted into the groove 310, the protrusion 210 can effectively resist the action of external force to prevent deformation or damage, thereby ensuring that the connection between the enameled wires is firm and reliable.

[0046] The first metal sheet 410 and the second metal sheet 420 are made of beryllium bronze material, which has extremely high strength and hardness. When the protrusion 210 applies a squeezing force, this high strength can effectively resist the external force and prevent the metal sheet from breaking easily. At the same time, beryllium bronze also has good elasticity. When the first metal sheet 410 and the second metal sheet 420 are squeezed, the first metal sheet 410 and the second metal sheet 420 can undergo moderate deformation and store a certain amount of elastic potential energy. This elasticity enables the first metal sheet 410 and the second metal sheet 420 to fit tightly with the protrusion 210 and generate a reaction force to tightly clamp the protrusion 210.

[0047] In order to ensure the stability of the connection between the protruding snap-fit ​​structure 200, the recessed receiving structure 300 and the fastening mechanism 400, as shown in FIG. Figure 1 As shown, there are multiple groups of protruding snap-fit ​​structures 200, recessed receiving structures 300 and fastening mechanisms 400, which are evenly arranged on the outer wall of the aluminum core body 100. The multiple groups can disperse the external force to different positions to avoid stress concentration in one place. When the aluminum core body 100 is subjected to external forces such as stretching, bending or torsion, the multiple groups of connection structures jointly bear these forces, so that the stress on each connection point is reduced, thereby improving the stability of the overall connection.

[0048] Working principle: When the aluminum core body 100 needs to be wound, the aluminum core body 100 is wound so that the folded area of ​​the aluminum core body 100 is fitted, and the protrusion 210 on the second aluminum wire is aligned with the groove 310 of the first aluminum wire where it fits, and then the second aluminum wire is squeezed. Under the action of external force, the protrusion 210 on the second aluminum wire can be clamped into the groove 310 of the first aluminum wire, so that the winding of the aluminum core body 100 is tighter;

[0049] And when the protrusion 210 on the No. 2 aluminum wire is clamped into the groove 310 on the No. 1 aluminum wire, the protrusion 210 on the No. 2 aluminum wire squeezes the No. 1 metal sheet 410, and the No. 1 metal sheet 410 is squeezed and deformed. The reaction force of the No. 1 metal sheet 410 is applied to the outer wall of the protrusion 210 on the No. 2 aluminum wire, so that the No. 1 metal sheet 410 can tightly clamp the protrusion 210 on the No. 2 aluminum wire. The additional clamping force makes the protrusion 210 on the No. 2 aluminum wire more stable in the groove 310 on the No. 1 aluminum wire, and it is not easy to loosen or fall out. When the protrusion 210 on the No. 2 aluminum wire moves, it drives the No. 2 metal sheet 420 to move and squeeze and clamp with the inner wall of the groove 310 on the No. 1 aluminum wire. The elastic force of the No. 2 metal sheet 420 further improves the stability of the connection between the protrusion 210 on the No. 2 aluminum wire and the groove 310 on the No. 1 aluminum wire.
