[0002] Wrapped wire is a type of electromagnetic wire. It is an insulated wire used for coils or windings in electrical products. It is mainly used in motors, electrical appliances, instruments, transformers, etc., and produces electromagnetic effects by winding coils. Once the insulating material on the surface of the wrapped wire is worn, its high-voltage resistance will be greatly reduced, resulting in safety hazards during use. Therefore, wrapped wires with higher voltage levels need to have excellent wear resistance. In addition, the mechanical properties of the wrapped wire are also key indicators to measure its quality. The higher the mechanical strength, the less likely the wrapped wire is to be damaged by external forces. Therefore, it is necessary to develop high-voltage and high-strength glass fiber tape insulated wrapped wires.

[0003] After searching, it was found that the application number is CN202020673565.7, a tensile-resistant wrapped wire. This tensile-resistant wrapped wire uses a polytetrafluoroethylene composite tape to wrap the outside of the conductor layer, and a polytetrafluoroethylene film to wrap the outside of the polyimide layer. High temperature bonding is adopted, and the two are tightly combined. The insulation structure is simple, the design is reasonable, the temperature performance is good, and it is highly flame retardant. It adopts a double-layer wrapping structure, the cable surface is smooth and flat, and it has excellent wear resistance and cutting resistance, and has high mechanical strength. It has good resistance to environmental stress cracking and has strong resistance to longitudinal cutting and friction; however, the tensile-resistant wrapped wire still has shortcomings in wear resistance and extrusion resistance, which need to be improved.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In the utility model:

[0021] Example 1: Reference Figure 1-4 A high-voltage resistant and high-strength glass fiber tape insulated wrapped wire comprises an outer sheath 1, a polyester filler 101, a copper core wire 102, an inner sheath 103 and a glass fiber tape 3. The outer ring of the outer sheath 1 is wound with the glass fiber tape 3, and the glass fiber tape 3 is spirally arranged. The inner part of the outer sheath 1 is provided with a copper core wire 102, and there are three copper core wires 102, which are equidistantly arranged. The outer ring of the copper core wire 102 is fitted with the inner sheath 103, and the polyester filler 101 is filled between the inner part of the outer sheath 1 and the outer ring of the inner sheath 103.

The outer ring of the outer sheath 1 is respectively provided with a pressure-resistant buffer mechanism to resist external pressure, and a limiting and anti-shifting mechanism to prevent deflection and wear can be provided.

[0022] Reference Figure 1-4, further, the pressure-resistant buffer mechanism is composed of a high-temperature resistant sheath A2, a pressure-resistant sheath 201 and a high-temperature resistant sheath B202;

[0023] The outer ring of the outer sheath 1 is fitted with a high-temperature resistant sheath A2, the outer ring of the high-temperature resistant sheath A2 is fitted with a pressure-resistant sheath 201, and a high-temperature resistant sheath B202 is fitted between the outer ring of the pressure-resistant sheath 201 and the inner ring of the glass fiber belt 3, and the surfaces of the inner and outer rings of the pressure-resistant sheath 201, the inner ring of the high-temperature resistant sheath B202 and the outer ring of the high-temperature resistant sheath A2 are all wavy. The materials of the high-temperature resistant sheath A2 and the high-temperature resistant sheath B202 are both cross-linked polyethylene, and the material of the pressure-resistant sheath 201 is foam rubber. When the staff uses the winding wire to wind the designated stator and winds the winding wire inside the designated stator, it will generate extrusion pressure on the high-temperature resistant sheath A2, the pressure-resistant sheath 201 and the high-temperature resistant sheath B202. At this time, the wavy pressure-resistant sheath The surfaces of the inner and outer rings of 201, the inner ring of the high-temperature resistant sheath B202 and the outer ring of the high-temperature resistant sheath A2 will disperse the extrusion force to the surroundings, so that the extrusion force is evenly distributed. At the same time, the compression-resistant sheath 201 made of foam rubber with impact resistance, high elasticity and good mechanical strength can prevent the winding wire from being bent at a large angle and causing damage to the internal copper core wire 102. At the same time, it can protect the copper core wire 102 from being squeezed and damaged by large pressure, thereby improving the overall compression buffering effect of the winding wire. At the same time, the cross-linked polyethylene material high-temperature resistant sheath A2 and high-temperature resistant sheath B202, which are heat-resistant, corrosion-resistant and have low thermal conductivity, will not cause the cable to be affected by high temperature and cause safety hazards when subjected to external high temperature.

[0024] Reference Figure 1-4 , further, the position limiting and anti-shifting mechanism is composed of a position limiting slot 105 and a position limiting strip 203;

[0025] The inner ring of the high temperature resistant sheath A2 is fixedly installed with a limit card strip 203, and there are four limit card strips 203, which are arranged equidistantly in a trapezoidal shape. The outer ring of the outer sheath 1 is embedded with a limit card slot 105, and there are four limit card slots 105, which are arranged equidistantly in a trapezoidal shape, and the limit card strip 203 is fitted and slidably arranged on the inner side of the limit card slot 105. When the staff uses the winding wire to wind the designated stator and winds the winding wire inside the designated stator, the high temperature resistant sheath A2 will be limited to the inner side of the limit card slot 105 by the limit card strip 203 of the inner ring, so that the high temperature resistant sheath A2 is always firmly fitted with the outer ring of the outer sheath 1, and it will not easily rotate when bending to cause friction and wear, so that the outer sheath 1 can protect the internal copper core wire 102 for a longer time, and improve the effect of stable anti-displacement wear between the outer sheath 1 and the high temperature resistant sheath A2.

[0026] Reference Figure 1-3 , further, the limiting mechanism is composed of a limiting groove 104;

[0027] The inner circle of the outer sheath 1 is embedded with a limiting groove 104, and there are three limiting grooves 104, which are arranged equidistantly in an arc shape, and the inner sheath 103 is arranged on the inner side of the limiting groove 104 in a fitting contact manner. When the staff uses the winding wire to wind the designated stator and winds the winding wire inside the designated stator, the inner sheath 103 of the outer circle of the copper core wire 102 will be squeezed and fitted between the limiting groove 104 of the inner circle of the outer sheath 1. When the winding wire is bent, the copper core wire 102 will always be on the inner side of the limiting groove 104, which can avoid the displacement of the inner sheath 103 during bending and the friction with the outer sheath 1 to cause wear, thereby improving the anti-wear effect between the outer sheath 1 and the inner sheath 103.

[0028] Embodiment 2:

[0029] like Figure 4 , 5 As shown, in addition to the embodiment in which the inner ring of the high temperature resistant sheath A2 is fixedly installed with a limit card strip 203, there are four limit card strips 203, and they are arranged around in a trapezoidal shape and are equidistant, the outer ring of the outer sheath 1 is embedded with a limit card slot 105, there are four limit card slots 105, and they are arranged around in a trapezoidal shape and are equidistant, and the limit card strip 203 is fitted and slidably arranged on the inner side of the limit card slot 105, there is another embodiment in which the inner ring of the high temperature resistant sheath A2 is fixedly installed with a limit card strip 203, there are four limit card strips 203, and they are arranged around in a trapezoidal shape, the outer ring of the outer sheath 1 is embedded with a limit card slot 105, there are four limit card slots 105, and they are arranged around in a trapezoidal shape and are equidistant. The limiting card strip 203 is arranged in a wavy shape, and the limiting card strip 203 is arranged in a slidable manner on the inner side of the limiting card slot 105. When the staff uses the winding wire to wind the designated stator and winds the winding wire inside the designated stator, the high temperature resistant sheath A2 will contact the inner wall of the limiting card slot 105 with a larger area through the limiting card strip 203 of the inner ring, thereby generating greater friction for stable limiting, so that the high temperature resistant sheath A2 is always firmly fitted with the outer ring of the outer sheath 1, and will not easily rotate when bending to cause friction and wear. Compared with the first embodiment, the limiting effect is better.

[0030] Working principle: First, the staff uses the wrapping wire to wind the designated stator. When the wrapping wire is wound inside the designated stator, it will generate extrusion pressure on the high temperature resistant sheath A2, the pressure resistant sheath 201 and the high temperature resistant sheath B202. At this time, the wavy inner and outer rings of the pressure resistant sheath 201, the inner ring of the high temperature resistant sheath B202 and the outer ring of the high temperature resistant sheath A2 will disperse the extrusion pressure to the surroundings, so that the extrusion pressure is evenly distributed. At the same time, the pressure resistant sheath 201 made of foam rubber with impact resistance, high elasticity and good mechanical strength can avoid the large-angle bending of the wrapping wire, which may cause damage to the internal copper core wire 102, and protect the The copper core wire 102 will not be squeezed and damaged by large pressure. The cross-linked polyethylene high-temperature resistant sheath A2 and high-temperature resistant sheath B202, which are heat-resistant, corrosion-resistant and have low thermal conductivity, will not cause the cable to be affected by high temperature and cause safety hazards when subjected to external high temperature. Then, the high-temperature resistant sheath A2 will be limited to the inner side of the limiting groove 105 by the limiting card strip 203 of the inner ring, so that the high-temperature resistant sheath A2 is always firmly fitted between the outer ring of the outer sheath 1. Finally, the inner sheath 103 of the outer ring of the copper core wire 102 will be squeezed and fitted between the limiting groove 104 of the inner ring of the outer sheath 1. When the wrapped wire is bent, the copper core wire 102 will always be in the limiting groove

[0031] The inner side of 104 can prevent the inner sheath 103 from displacement and friction with the outer sheath 1 when bending, and will not easily rotate when bending to cause friction and wear, so that the outer sheath 1 can protect the internal copper core wire 102 more permanently.
