Self-adhesive mica tape winding wire

Abstract

The invention discloses a self-adhesive mica tape winding wire, which belongs to the technical field of motor accessories. The winding wire comprises a conductor and an insulator combined outside the conductor. The insulator comprises a first mica tape wound outside the conductor; a film and the first mica tape which are wound outside the conductor in turn; a packaging layer combined outside the conductor by sintering or hot sealing and the first mica tape wound outside the packaging layer; a second mica tape and the first mica tape which are wound outside the conductor in turn; the second mica tape, a third mica tape and the first mica tape which are wound outside the conductor in turn; the film, the second mica tape and the first mica tape which are wound outside the conductor in turn; or the packaging layer combined outside the conductor by sintering or hot sealing and the second mica tape and the first mica tape which are wound outside the packaging layer in turn. The winding wire is characterized in that the outside lateral surface of the first mica tape is combined with a self-adhesive layer. Most ideally, the self-adhesive property is favorable for the shaping of a coil; and environmental influences are avoided and process steps in a manufacturing process are reduced.

Description

technical field [0001] The invention belongs to the technical field of motor accessories, in particular to a self-adhesive mica tape wrapping wire. Background technique [0002] The structure of the mica tape wrapping wire in the prior art generally has the following several types: the one is to wrap polyimide film or wrap polyester film outside the flat conductor such as copper or copper-clad aluminum, and then wrap the polyimide film on the polyimide Amine film or polyester film is wrapped with mica tape. Because the mica tape wrapping wire of this structure does not have self-adhesive properties, it is not conducive to the shaping of the coil during use, which makes installation and use difficult; the second is to wrap polyimide on the flat conductor of copper or copper-clad aluminum. Amine film, polyester film or mica tape, and then wrap mica tape outside, and then wrap single-layer or double-layer glass filament outside the mica tape, and dip it in paint, add self-adhe...
