Description

Technical Field

[0001] The utility model belongs to the technical field of braided film-covered wires, and particularly relates to a braided film-covered wire with corrosion resistance effect. Background Technique

[0002] The braided film-covered wire, also known as film-covered wire or Mylar wire, is an electromagnetic wire with a synthetic film or other material film coated on the surface of a wire or enameled stranded wire as an insulating layer. The braided film-covered wire is based on LITZ wire, enameled stranded wire, etc., with an additional layer or multiple layers of Mylar film or other synthetic films to increase the insulation voltage and shielding performance of the wire;

[0003] Its structure generally includes an internal wire or stranded wire and an external insulating layer. The insulating layer can be a single-layer or multi-layer film, such as PET (polyethylene terephthalate), ETFE (ethylene-tetrafluoroethylene copolymer), PI (polyimide), etc. The specific material depends on application requirements and performance requirements. Due to its excellent performance, the braided film-covered wire is widely used in high-frequency transformers, high-power transformers, magnetic rings and other fields. Especially in high-end electronic devices such as medical equipment, inverters, high-frequency inductors and transformers, wireless chargers, etc., during the long-term use of the braided film-covered wire, the insulating material ages rapidly, resulting in a significant reduction in the overall strength of the braided film-covered wire, causing cracks on the surface of the braided film-covered wire, and then losing the original protection performance of the braided film-covered wire, thus increasing the risk of corrosion of the braided film-covered wire. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a braided film-covered wire with corrosion resistance effect, aiming to solve the problem that during the long-term use of the above-mentioned braided film-covered wire in the prior art, the insulating material ages rapidly, resulting in a significant reduction in the overall strength of the braided film-covered wire, causing cracks on the surface of the braided film-covered wire, and then losing the original protection performance of the braided film-covered wire, thus increasing the risk of corrosion of the braided film-covered wire.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A braided film-covered wire with corrosion resistance effect, including a wire core and an insulating layer wrapped on the surface of the wire core, and a support layer is wrapped outside the insulating layer;

[0006] A braided layer is wrapped outside the support layer, an outer protection layer is wrapped outside the braided layer, reinforcing ribs are connected to the outer side wall of the support layer, and the braided layer is composed of transverse copper wires, longitudinal copper wires and high molecular fiber filaments.

[0007] Preferably, for the braided film-covered wire with corrosion resistance effect of the utility model, the reinforcing ribs are in an interlaced winding structure, and the reinforcing ribs are made of polyester fiber material.

[0008] Preferably, for the braided film enameled wire with corrosion resistance effect of the present utility model, the horizontal copper wires and the vertical copper wires are woven in a crisscross manner.

[0009] Preferably, for the braided film enameled wire with corrosion resistance effect of the present utility model, the high molecular fiber filaments pass through the gaps at the joints of the horizontal copper wires and the vertical copper wires and are woven in a crisscross manner.

[0010] Preferably, for the braided film enameled wire with corrosion resistance effect of the present utility model, a waterproof film is coated on the inner side of the outer protective layer close to the braided layer, and a reserved cavity is provided on the inner side of the outer protective layer close to the waterproof film.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] By arranging a support layer with reinforcing ribs on the surface of the insulating layer, the overall strength and corrosion resistance of the enameled wire are improved. At the same time, the anti-twisting performance of the braided film enameled wire is enhanced by adopting a braided layer in a crisscross manner. In addition, high molecular fiber filaments are used to ensure that there are no gaps at the crisscross positions of the braided layer, thereby reducing the braided gaps and preventing the penetration of corrosive media, and further enhancing the corrosion resistance of the braided film enameled wire.
