Description

TECHNICAL FIELD

[0001] The utility model relates to an electromagnetic wire, in particular to a multi-core wear-resistant enameled wire. BACKGROUND

[0002] Enameled wire is a main variety of winding wire, which is composed of a conductor and an insulating layer. After the bare wire is annealed and softened, it is baked after being coated with paint for multiple times. However, it is not easy to produce a product that meets the standard requirements and customer requirements. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires are different, but they all have mechanical properties, chemical properties, electrical properties, and thermal properties.

[0003] As disclosed in the patent with application number 202322541535.7, a parallel multi-core composite enameled wire is provided. The wire cores are arranged in parallel, and each wire core is composed of an inner core and an insulating paint layer wrapped around the outer side of the inner core. An outer paint layer is wrapped around the outer side of the wire core. However, during use, the thickness of the outer paint layer of the wire core varies greatly, and the paint film is prone to breakage, which affects the reliability of the enameled wire. SUMMARY

[0004] The utility model aims to provide a multi-core wear-resistant enameled wire. It has the advantages of wear resistance and breakage prevention while having multiple wire cores.

[0005] The technical solution of the utility model is a multi-core wear-resistant enameled wire, which includes multiple groups of wire cores arranged in parallel and having insulating paint layers on the outer sides. An insulating fiber is arranged outside the wire cores to wrap the multiple groups of wire cores. A support layer is arranged on the outer side of the insulating fiber. A heat-conducting filler is arranged between the insulating fiber and the support layer. A wear-resistant sleeve is arranged outside the support layer.

[0006] In the aforementioned multi-core wear-resistant enameled wire, the insulating fiber is perpendicular to the axis direction of the wire core, and the insulating fiber is a ceramic fiber.

[0007] In the aforementioned multi-core wear-resistant enameled wire, the support layer has multiple arc-shaped clamping grooves corresponding to the insulating fiber, and a reinforcing rib is arranged between the arc-shaped clamping grooves.

[0008] In the aforementioned multi-core wear-resistant enameled wire, the support layer and the reinforcing rib on the support layer are made of rubber.

[0009] Compared with the prior art, the utility model reduces the required space by arranging multiple groups of wire cores arranged in parallel and having their axes on the same plane. The heat-conducting filler improves the heat dissipation effect, avoids heat accumulation, and prolongs the service life of the enameled wire. The arrangement of the insulating fiber and the wear-resistant sleeve makes the spacing between the wire cores more accurate. BRIEF DESCRIPTION OF DRAWINGS
