Technical Field

The utility model relates to an enameled wire field, in particular to 200 level anti enameled copper round wires of buckling.

Background

With the rapid development of the domestic electronic industry, enameled wires are widely applied to various fields, and with the continuous upgrading of domestic products, people have increasingly high requirements on high-quality enameled wires. The enameled wire is a main variety of winding wires and consists of a conductor and an insulating layer, and a bare wire is annealed and softened and then is subjected to painting and baking for multiple times. However, it is not easy to produce a product which meets both the standard requirements and the customer requirements, and it is affected by the quality of raw materials, process parameters, production equipment, environment, and other factors, so the quality characteristics of various enameled wires are different.

Currently, a part of the enameled wires is used as signal wires for controlling mechanical actions of the machine, such as rotation and movement. When the mechanical part is mechanically operated, the enameled wire is often bent and cannot be restored to the original shape, so that the enameled wire is locally uneven, and the electrical performance is affected.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a 200 level anti enameled copper round wire of buckling, it has the advantage that can make the enameled wire resume deformation after buckling.

the utility model provides a 200 level anti bending enameled copper round wire, includes copper core, insulating paint layer, soft protective layer, bending resistance folding layer and the outer cladding layer that from inside to outside successive layer set up, insulating paint layer evenly sets up in the surface of copper core, bending resistance folding layer comprises a plurality of elastic wires, the mutual crisscross cooperation of elastic wire forms the anti bending net of cladding on soft protective layer, the outer cladding layer cladding is on bending resistance folding layer and with bending resistance folding layer and external separation.

By adopting the technical scheme, the insulating paint layer protects the copper core, and the copper core is prevented from being in contact with the outside to generate electric leakage or short circuit. Because the anti-bending net is coated on the soft protective layer, when external force acts on the enameled copper round wire to enable the copper core and the soft protective layer to be subjected to bending deformation, the part of the anti-bending net on the inner side of the bending is compressed, and the part of the anti-bending net on the outer side of the bending is stretched. When the external force acting on the enameled round copper wire disappears, the internal stress of the anti-bending net can restore the deformation of the anti-bending net, so that the deformation of the copper core and the soft protective layer is driven to restore.

Further setting: the soft protective layer is made of soft materials, and a plurality of bubbles are uniformly distributed in the soft materials.

By adopting the technical scheme, when the bending-resistant folded layer and the outer cladding layer are bent, the soft materials on the inner side and the outer side of the bending can be extruded to deform, and the phenomenon that the bending-resistant folded layer and the outer cladding layer directly extrude the copper core to cause the copper core to deform is avoided.

Further setting: the outer cladding layer is provided with a plurality of reinforcing ribs in the length direction of the copper core.

By adopting the technical scheme, when the outer cladding layer is bent under the action of external force, the reinforcing rib on the inner side of the bending is extruded to transmit the force to the whole reinforcing rib, the reinforcing rib on the outer side of the bending is stretched to transmit the force to the whole reinforcing rib, the whole reinforcing rib is deformed to reduce the local bending radian, and the phenomenon that the copper core is plastically deformed by the overlarge bending radian to cause local unevenness and influence on electrical performance is avoided.

Further setting: the outer cladding layer and the reinforcing ribs are made of waterproof resin.

Through adopting above-mentioned technical scheme, waterproof resin has better waterproof performance, can also provide certain intensity for the copper core.

Further setting: an electric shielding net is arranged between the insulating paint layer and the soft protective layer.

Further setting: the electric shielding net is made of aluminum wires or copper wires.

Through adopting above-mentioned technical scheme, the electric shield net can keep apart copper core and external world, and the electric shield net of knowing the metal and making by the gaussian law makes electric shielding layer both sides become two isolated electromagnetism areas relatively, influences each other with the external world when avoiding inside copper core to produce alternating magnetic field.

Further setting: the insulating paint layer is a polyurethane insulating coating.

Further setting: the temperature grade of the polyurethane insulating coating is 200 grades.

By adopting the technical scheme, the polyurethane insulating coating can ensure that the surface of the enameled wire is uniform and smooth, has no burrs and high temperature resistance level and is insulated from the outside.

To sum up, the utility model discloses following beneficial effect has:

1. when the external force applied to the copper round wire to bend the copper round wire disappears, the bending-resistant layer can recover the deformation of the copper round wire, and the phenomenon that the local unevenness of the enameled wire affects the electrical performance is avoided;

2. the reinforcing ribs and the soft protective layer can avoid the risk of plastic deformation caused by local excessive bending of the enameled wire;

3. simple and stable structure and convenient production.

Detailed Description

A200-grade bending-resistant enameled round copper wire is shown in figure 1 and comprises a copper core 1, an insulating paint layer 2, an electric shielding net 3, a soft protective layer 4, a bending-resistant layer 5 and an outer cladding layer 6 which are arranged layer by layer from inside to outside.

Copper core 1 is the copper round wire, and insulating paint layer 2 evenly sets up in the surface of copper core 1, and is made by insulating material, and insulating paint layer 2 is polyurethane insulation coating in this embodiment, and this polyurethane insulation coating's temperature rank is 200 grades. The polyurethane insulating coating can ensure that the surface of the enameled wire is uniform and smooth, has no burrs and high temperature resistance level and is insulated from the outside.

The electric shielding net 3 is coated on the insulating paint layer 2 and is made of aluminum wires or copper wires. The electric shielding net 3 can isolate the copper core 1 from the outside, and the electric shielding net 3 made of metal can be known by the Gaussian theorem to enable two sides of the electric shielding layer to become two relatively isolated electromagnetic regions so as to avoid the mutual influence between the inside copper core 1 and the outside when the inside copper core 1 generates an alternating magnetic field.

The soft protective layer 4 is coated on the surface of the insulating paint layer 2 and is made of soft material, and a plurality of bubbles are uniformly distributed in the soft material. In this embodiment, the soft material is sponge rubber. The sponge rubber is a porous structure material with pores distributed throughout the whole material, and has small density and excellent elasticity and flexibility. When the bending-resistant folded layer 5 and the outer cladding layer 6 are bent, the soft materials on the inner side and the outer side of the bend are extruded to deform, and the phenomenon that the bending-resistant folded layer 5 and the outer cladding layer 6 directly extrude the copper core 1 to cause the copper core 1 to deform is avoided.

The bending-resistant layer 5 is composed of a plurality of elastic threads 51, a plurality of auxiliary threads are arranged and matched with each other in a staggered manner to form a bending-resistant net 52, and the bending-resistant net 52 is coated on the soft protective layer 4 and separates the bending-resistant layer 5 from the outside. When an external force acts on the enameled round copper wire to cause bending deformation on the copper core 1 and the soft protective layer 4, the part of the anti-bending net 52 on the inner side of the bending is compressed, and the part of the anti-bending net 52 on the outer side of the bending is stretched. When the external force applied to the enameled round copper wire disappears, the internal stress of the bending-resistant net 52 will restore the deformation of the bending-resistant net 52, so as to drive the copper core 1 and the soft protection layer 4 to restore the deformation.

The outer cover 6 is made of a waterproof material, and in the present embodiment, the outer cover 6 is made of a waterproof resin. The outer cladding 6 is integrally provided with a plurality of reinforcing ribs 61 in the length direction of the copper core 1, the number of the reinforcing ribs 61 is six in the present embodiment, and the reinforcing ribs are also made of waterproof resin and are all uniformly arranged around the axis of the copper core 1.
