Description

Technical Field

[0001] This invention relates to the field of enameled wire technology, specifically to a pressure-resistant and wear-resistant enameled wire. Background Technology

[0002] Enamelled wire is a type of metal conductor coated with insulating varnish, also known as electromagnetic wire. It is mainly used for winding electromagnetic coils. It consists of two parts: a conductor such as copper or aluminum and an insulating layer. It is made through processes such as annealing and softening, multiple coatings, and baking. It has good mechanical, chemical, electrical, and thermal properties and is a key raw material for electromagnetic windings in products such as motors, household appliances, and electronic instruments.

[0003] For example, Chinese Patent Application No. 202222284601.2 discloses an enameled wire that, radially from the inside out, comprises a conductor, a first primer layer, a middle varnish layer, and a topcoat layer. The first primer layer accounts for 5%-15% of the volume, the second primer layer accounts for 25%-35%, and the middle or topcoat layer is a corona-resistant layer, accounting for 35%-65% of the volume. This invention improves the reliability of the insulation system by setting up a first primer layer, a second primer layer, a middle varnish layer, and a topcoat layer, wherein the corona-resistant layer is either the middle or topcoat layer, and by rationally configuring the volume proportions of each layer, thus mitigating losses caused by partial discharge.

[0004] However, the enameled wires described above have poor compressive strength and abrasion resistance during use, and are easily scratched or damaged during transportation due to handling and stacking. Therefore, those skilled in the art have provided a compressive strength and abrasion resistance enameled wire to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to provide a pressure-resistant and wear-resistant enameled wire to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A pressure-resistant and wear-resistant enameled wire includes a built-in core, an insulating varnish layer on the outside of the built-in core, a rubber pressure-resistant layer on the outside of the insulating varnish layer, a reinforcing skeleton mechanism on the outside of the rubber pressure-resistant layer, a high-hardness ceramic layer on the outside of the reinforcing skeleton mechanism, a nylon wear-resistant sleeve on the outside of the high-hardness ceramic layer, multiple heat dissipation holes for the core inside the rubber pressure-resistant layer, multiple cutting indicators on the outside of the nylon wear-resistant sleeve, and a reinforcing and limiting mechanism inside the high-hardness ceramic layer.

[0008] The reinforced skeleton mechanism includes a reinforced fiber mesh layer, the inner wall of which is fixed with a plurality of positioning reinforcing ribs, and the two ends of the reinforced fiber mesh layer are fixed with connecting positioning blocks, the two ends of which are provided with connecting positioning grooves.

[0009] As a further aspect of the present invention: the outer wall of the rubber compression-resistant layer is provided with an arc-shaped groove, the size of which is adapted to the size of the positioning reinforcing rib. The rubber compression-resistant layer is wrapped around the inner core and the insulating varnish layer. The rubber compression-resistant layer can absorb a certain amount of impact energy and resist bending to prevent excessive deformation. The outer side of the rubber compression-resistant layer is wrapped with a reinforcing fiber mesh layer. The beginning and end connection parts of the reinforcing fiber mesh layer are provided with connecting positioning blocks and connecting positioning grooves. The corresponding connecting positioning blocks are movably inserted into the connecting positioning grooves and bonded and fixed. The reinforcing fiber mesh layer forms a mesh structure through fiber reinforcement material, which evenly disperses stress and enhances the overall compression resistance. The positioning reinforcing ribs on the inner wall of the reinforcing fiber mesh layer not only play a reinforcing role, but also, the positioning reinforcing ribs are inserted into the pre-set arc-shaped grooves of the rubber compression-resistant layer, which can ensure a tight connection between the reinforcing fiber mesh layer and the rubber compression-resistant layer. The outer side of the reinforcing skeleton structure is wrapped with a high-hardness ceramic layer. The high-hardness ceramic layer can improve surface hardness and wear resistance. The nylon wear-resistant sleeve on the outside of the high-hardness ceramic layer provides basic wear-resistant protection and can reduce wear caused by external friction.

[0010] As a further embodiment of the present invention: the size of the connecting positioning block is adapted to the size of the connecting positioning groove, and the reinforcing fiber mesh layer is specifically installed between the rubber compression layer and the high-hardness ceramic layer.

[0011] As a further embodiment of the present invention: the reinforcing limiting mechanism includes a return spring, one end of the return spring is connected to a limiting pad, a positioning reinforcing block is fixed on one side of the limiting pad and extends through the other side, a limiting connecting post is fixed on one side of the limiting pad, and a limiting connecting sleeve is movably sleeved on the outer side of the limiting connecting post.

[0012] As a further aspect of the present invention: the limiting connecting sleeve and the high-hardness ceramic layer are fixedly connected. The high-hardness ceramic layer has a through hole inside to accommodate the movement of the positioning reinforcement block. The return spring inside the high-hardness ceramic layer provides elastic force to push the limiting pad, allowing the positioning reinforcement block on one side of the limiting pad to penetrate the high-hardness ceramic layer and extend into the preset positioning groove of the reinforcing fiber mesh layer. The outer side of the positioning reinforcement block has a chamfer, which will not affect the normal installation of the reinforcing fiber mesh layer. One end of the limiting connecting column moves within the limiting connecting sleeve and plays a guiding role, preventing the positioning reinforcement block from tilting. By supporting and limiting the outer wall of the reinforcing fiber mesh layer through the positioning reinforcement block, the connection stability of the reinforcing fiber mesh layer is improved.

[0013] As a further aspect of the present invention: a positioning groove is provided inside the reinforcing fiber mesh layer, the size of which is adapted to the size of the positioning and reinforcing block.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. This device is equipped with a reinforcing skeleton mechanism. The reinforced fiber mesh layer forms a mesh structure through fiber reinforcement materials, which evenly disperses stress and enhances the overall compressive strength. The high-hardness ceramic layer can improve surface hardness and wear resistance. The nylon wear-resistant sleeve provides basic wear-resistant protection and can reduce wear caused by external friction. Without affecting the flexibility and bending resistance of the enameled wire, it can enhance the compressive strength and wear resistance of the enameled wire and protect the internal metal conductor and insulating varnish film.

[0016] 2. By setting up a reinforcement and limiting mechanism, the positioning reinforcement block is prevented from tilting. The positioning reinforcement block supports and limits the outer wall of the reinforcing fiber mesh layer, which improves the connection stability of the reinforcing fiber mesh layer, ensures that the reinforcing fiber mesh layer is firmly connected to the wire body, prevents displacement during use, and the entire installation process will not damage the original insulation layer of the enameled wire.

[0024] The reinforced frame mechanism 4 includes a reinforcing fiber mesh layer 41. Multiple positioning reinforcing ribs 42 are fixed to the inner wall of the reinforcing fiber mesh layer 41. Connecting positioning blocks 43 are fixed to both ends of the reinforcing fiber mesh layer 41. Connecting positioning grooves 44 are formed at both ends of the connecting positioning blocks 43. An arc-shaped groove is formed on the outer wall of the rubber compression-resistant layer 3, the size of which matches the size of the positioning reinforcing ribs 42. The rubber compression-resistant layer 3 is wrapped around the inner core 1 and the insulating varnish layer 2. The rubber compression-resistant layer 3 can absorb a certain amount of impact energy and resist bending to prevent excessive deformation. The reinforcing fiber mesh layer 41 is wrapped around the outer side of the rubber compression-resistant layer 3. Connecting positioning blocks 43 and connecting positioning grooves 44 are provided at the beginning and end connection points of the reinforcing fiber mesh layer 41. The corresponding connecting positioning blocks 43 are movably inserted into the connecting positioning grooves 44. The reinforced fiber mesh layer 41 is bonded and fixed, forming a mesh structure through fiber reinforcement material, which evenly disperses stress and enhances the overall compressive strength. The positioning reinforcing ribs 42 on the inner wall of the reinforced fiber mesh layer 41 not only play a reinforcing role, but also fit into the pre-set arc-shaped groove of the rubber compressive layer 3, which can ensure a tight connection between the reinforced fiber mesh layer 41 and the rubber compressive layer 3. The outer side of the reinforcing skeleton mechanism 4 is wrapped with a high-hardness ceramic layer 5, which can improve surface hardness and wear resistance. The nylon wear-resistant sleeve 6 on the outer side of the high-hardness ceramic layer 5 provides basic wear-resistant protection and can reduce wear caused by external friction. The size of the connecting positioning block 43 is adapted to the size of the connecting positioning groove 44. The reinforced fiber mesh layer 41 is specifically installed between the rubber compressive layer 3 and the high-hardness ceramic layer 5.

[0025] In one embodiment of the present invention, the reinforcing limiting mechanism 8 includes a return spring 81, one end of which is connected to a limiting pad 82. A positioning reinforcing block 83 penetrating the other side is fixed to one side of the limiting pad 82. A limiting connecting post 84 is fixed to one side of the limiting pad 82. A limiting connecting sleeve 85 is movably sleeved on the outer side of the limiting connecting post 84. The limiting connecting sleeve 85 is fixedly connected to the high-hardness ceramic layer 5. A through hole is opened inside the high-hardness ceramic layer 5 to accommodate the movement of the positioning reinforcing block 83. The return spring 81 inside the high-hardness ceramic layer 5 provides elastic force to push the limiting pad 82, allowing the limiting pad 82 to move. One side positioning reinforcement block 83 penetrates the high-hardness ceramic layer 5 and extends into the pre-set positioning groove of the reinforced fiber mesh layer 41. The outer side of the positioning reinforcement block 83 is chamfered so as not to affect the normal installation of the reinforced fiber mesh layer 41. One end of the limiting connecting column 84 moves in the limiting connecting sleeve 85 and plays a guiding role to prevent the positioning reinforcement block 83 from tilting. The positioning reinforcement block 83 supports and limits the outer wall of the reinforced fiber mesh layer 41, thereby improving the connection stability of the reinforced fiber mesh layer 41. The inside of the reinforced fiber mesh layer 41 is provided with a positioning groove, the size of which is adapted to the size of the positioning reinforcement block 83.

[0026] The working principle of this invention is as follows: This device is equipped with a reinforcing skeleton mechanism 4. A rubber compression-resistant layer 3 is wrapped around the inner core 1 and the insulating varnish layer 2. The rubber compression-resistant layer 3 can absorb a certain amount of impact energy and resist bending to prevent excessive deformation. A reinforcing fiber mesh layer 41 is wrapped around the outside of the rubber compression-resistant layer 3. A connecting positioning block 43 and a connecting positioning groove 44 are provided at the beginning and end connection parts of the reinforcing fiber mesh layer 41. The corresponding connecting positioning block 43 is movably inserted into the connecting positioning groove 44 and bonded and fixed. The reinforcing fiber mesh layer 41 is... The fiber-reinforced material forms a mesh structure, which evenly disperses stress and enhances the overall compressive strength. The positioning reinforcing ribs 42 on the inner wall of the reinforced fiber mesh layer 41 not only play a reinforcing role, but also, when the positioning reinforcing ribs 42 are inserted into the pre-set arc-shaped grooves of the rubber compressive layer 3, they can ensure a tight connection between the reinforced fiber mesh layer 41 and the rubber compressive layer 3. The outer side of the reinforcing skeleton structure 4 is wrapped with a high-hardness ceramic layer 5, which can improve surface hardness and wear resistance. The nylon wear-resistant sleeve 6 on the outer side of the high-hardness ceramic layer 5 provides basic wear resistance. Abrasion protection can reduce wear caused by external friction. Without affecting the flexibility and bending resistance of the enameled wire, it can enhance the compressive strength and abrasion resistance of the enameled wire and protect the internal metal conductor and insulating varnish film. With the reinforcement limiting mechanism 8, after the reinforcing fiber mesh layer 41 is installed between the high-hardness ceramic layer 5 and the rubber compression-resistant layer 3, the return spring 81 in the high-hardness ceramic layer 5 provides elastic force to push the limiting pad 82, so that the positioning reinforcement block 83 on one side of the limiting pad 82 penetrates the high-hardness ceramic layer 5 and extends to the reinforcing fiber mesh layer 41. The pre-set positioning groove and the chamfered outer side of the positioning reinforcement block 83 will not affect the normal installation of the reinforcing fiber mesh layer 41. One end of the limiting connecting post 84 moves within the limiting connecting sleeve 85 and plays a guiding role, preventing the positioning reinforcement block 83 from tilting. The positioning reinforcement block 83 supports and limits the outer wall of the reinforcing fiber mesh layer 41, improving the connection stability of the reinforcing fiber mesh layer 41, ensuring that the reinforcing fiber mesh layer 41 is firmly connected to the wire body, preventing displacement during use, and the entire installation process will not damage the original insulation layer of the enameled wire.
