Description

Technical Field

[0001] The utility model relates to the technical field of enameled wires, in particular to a wear-resistant enameled wire. Background Art

[0002] Enameled wire is a main type of winding wire, consisting of a conductor and an internal insulating layer. The bare wire is annealed and softened, then painted and baked multiple times. The quality characteristics of enameled wire vary, but all have four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties.

[0003] For example, Chinese patent CN219891922U discloses a wear-resistant enameled wire, including a base layer, a built-in insulating layer arranged on the periphery of the base layer, a shielding layer arranged on the periphery of the built-in insulating layer, an anti-corrosion layer arranged on the periphery of the shielding layer, a flame retardant layer arranged on the periphery of the anti-corrosion layer, a wear-resistant layer arranged on the periphery of the flame retardant layer, and an outer protective layer arranged on the periphery of the wear-resistant layer; the wear-resistant layer includes a reinforcing strip, an inner layer, a wear-resistant strip and an outer layer, and the reinforcing strip and the wear-resistant strip are alternately arranged on the periphery of the inner layer in sequence. Although the above patent solves the problem of easy wear and increased safety hazards of the enameled wire after long-term use through the wear-resistant strip and the outer layer, the moisture-proof ability of the outside of the enameled wire is relatively low. When the wire body encounters moisture during use, water vapor easily enters the inside of the wire body, reducing the insulation inside the enameled wire, thereby causing the wire body to short-circuit. Utility Model Content

[0004] The utility model aims to solve the problems existing in the prior art and provides a wear-resistant enameled wire.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0012] Preferably, a buffer strip is clamped on one side of the clamping groove, and one side of the buffer strip is fixedly connected to the buffer layer.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. The moisture-proof protective layer of the utility model is compounded between the anti-aging protective layer and the waterproof isolation layer. The waterproof isolation layer is connected to the inner annular surface of the moisture-proof protective layer, and the anti-aging protective layer is connected to the outer annular surface of the moisture-proof protective layer.

The moisture-proof protective layer and the waterproof isolation layer are used in combination to reduce the influence of water vapor on the inside of the wire body, ensure the insulation inside the wire body, and thus improve the safety of the wire body when in use;

[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1, refer to Figure 1-4 As shown: a wear-resistant enameled wire, including a built-in insulating layer 7, the inner ring surface of the built-in insulating layer 7 is filled with a filling layer 2, a copper core 1 is inserted through the filling layer 2, and the outer ring surface of the built-in insulating layer 7 is compounded with a reinforcement auxiliary layer 8, the outer ring surface of the reinforcement auxiliary layer 8 is compounded with an anti-extrusion layer 6, the outer ring surface of the anti-extrusion layer 6 is compounded with a waterproof isolation layer 9, the outer ring surface of the waterproof isolation layer 9 is compounded with a moisture-proof protective layer 5, a waterproof coating is provided on one side of the waterproof isolation layer 9, the outer ring surface of the moisture-proof protective layer 5 is compounded with an anti-aging protective layer 4, the thickness of the moisture-proof protective layer 5 is the same as that of the anti-aging protective layer 4, the outer ring surface of the anti-aging protective layer 4 is compounded with a wear-resistant outer layer 3, the thickness of the wear-resistant outer layer 3 is 1.5 times that of the anti-aging protective layer 4, and the thickness of the waterproof isolation layer 9 is the same as that of the moisture-proof protective layer 5.

[0024] By filling the filling layer 2 inside the built-in insulating layer 7, the position of the copper core 1 inside the built-in insulating layer 7 can be limited, thereby improving the stability of the copper core 1 during use and reducing the displacement and deformation of the copper core 1. The waterproof isolation layer 9 can be used to provide waterproof protection for the inner ring surface of the moisture-proof protective layer 5, thereby preventing water vapor from entering the interior of the wire and interfering with the use of the copper core 1. The anti-aging protective layer 4 is wrapped around the outside of the moisture-proof protective layer 5 to reduce aging and damage of the moisture-proof protective layer 5 caused by ultraviolet radiation, thereby ensuring the moisture-proof effect of the moisture-proof protective layer 5 and improving the moisture-proof performance of the wire body. The wear-resistant outer layer 3 can be used to wrap and protect the outside of the anti-aging protective layer 4 to reduce the wear of the anti-aging protective layer 4.

[0025] Embodiment 2, as Figure 1-4 As shown, the thickness of the reinforcement auxiliary layer 8 is twice that of the built-in insulating layer 7, and the anti-extrusion layer 6 includes a connecting layer 601, a buffer strip 602 and a buffer layer 603. A snap-fit ​​groove is provided on one side of the connecting layer 601, and a buffer strip 602 is snapped on one side of the snap-fit ​​groove. One side of the buffer strip 602 is fixedly connected to the buffer layer 603.

[0026] The reinforcement auxiliary layer 8 can be used to wrap and protect the outside of the built-in insulating layer 7, reinforce the built-in insulating layer 7, and reduce damage to the built-in insulating layer 7, thereby ensuring the insulation protection effect of the built-in insulating layer 7 on the copper core 1 and the filling layer 2. The locking groove opened on one side of the connecting layer 601 can guide the connection between the connecting layer 601 and the buffer layer 603. The buffer strip 602 can assist the connection between the two sides of the buffer layer 603 and the connecting layer 601, thereby realizing the combination of the connecting layer 601 and the buffer layer 603 to form a complete anti-extrusion layer 6. The anti-extrusion layer 6 is used to improve the elasticity of the wire body and reduce the extrusion deformation and breakage of the wire body.

[0027] The use method and working principle of the device are as follows: first, a waterproof coating is arranged on the side of the waterproof isolation layer 9 close to the moisture-proof protective layer 5. The waterproof coating is made of waterproof paint. The wear-resistant outer layer 3 is made of silicone rubber. The wear-resistant outer layer 3 wraps the remaining structure of the wire body, so that the wear resistance of the wear-resistant outer layer 3 can be used to reduce the damage to the internal structure of the wire body. The surface of the anti-aging protective layer 4 is provided with a carbon black shading coating. The moisture-proof protective layer 5 is made of polyurethane material. The carbon black shading coating in the anti-aging protective layer 4 can be used to block the outside of the moisture-proof protective layer 5, which can reduce the damage of ultraviolet rays to the polyurethane in the moisture-proof protective layer 5. While ensuring the moisture-proof effect of the moisture-proof protective layer 5, the aging damage of the moisture-proof protective layer 5 to the moisture-proof protective layer 5 is reduced. The waterproof layer on the waterproof isolation layer 9 can prevent water from passing through the interior of the waterproof isolation layer 9, thereby preventing water vapor from entering the interior of the wire body and affecting the use of the copper core 1 inside the wire body. The anti-extrusion layer 6 is a three-layer structure. The connecting layer 601 is arranged on both sides of the buffer layer 603. The connecting layer 601 and the buffer layer 603 are connected by a buffer strip 602. The connecting layer 601 and the buffer layer 603 are both made of elastic materials. The three-layer structure is used in combination to improve the elasticity of the external wrapping material of the copper core 1, so that the external reinforcement auxiliary layer 8 can be wrapped and protected, the elasticity of the wire body can be increased, and the deformation caused by the extrusion of the wire body can be reduced. The reinforcement auxiliary layer 8 can be used to wrap and reinforce the outside of the built-in insulating layer 7 to reduce damage to the built-in insulating layer 7.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields.
