Description
Technical Field
The utility model belongs to the technical field of the electronic component technique and specifically relates to a fire-resistant electromagnetic wire.
Background
Magnet wires (magnet wires) are insulated electrical wires used to make coils or windings in electrical products. Also known as winding wire. Magnet wires must meet a variety of requirements for use and manufacturing processes. The former includes its shape, specification, ability to work at high temperature for a short time and a long time, and to withstand strong vibration and centrifugal force at high speed in some occasions, withstand corona and breakdown at high voltage, resist chemical corrosion under special atmosphere, etc.; the latter includes the requirements of being subjected to stretching, bending and abrasion during winding and inserting, swelling, erosion and the like during dipping and drying; however, when a short circuit occurs inside the magnet wire, a fire is easily caused in a short time, and a large area is damaged.
Disclosure of Invention
To the not enough of existence among the above-mentioned prior art, the utility model aims to provide a fire-resistant electromagnetic wire.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a refractory magnet wire, comprising: including sinle silk subassembly and mica tape, the mica tape twine in on the sinle silk subassembly, the sinle silk subassembly includes diolame and a plurality of sinle silk, the diolame wrap up in the sinle silk outside, the sinle silk is formed by the coiling of stranded wire.
Preferably, the wire is a copper wire.
Preferably, the envelope is a polyimide film.
Preferably, the mica tape is a synthetic mica tape.
Adopt above-mentioned scheme, the beneficial effects of the utility model are that:
the utility model designs a fire-resistant electromagnetic wire, and the wire core assembly is wrapped by the mica tape, so that the electromagnetic wire can not be directly burnt through the mica tape after short circuit occurs inside the electromagnetic wire, the mica tape has flame-retardant property, the burning occurrence time can be prolonged, the transformer can still work when a fire disaster occurs, and more time is won for rescue; through the arranged envelope, the wire core is in an insulation state with the outside.
