Description
Technical Field
The utility model relates to an inductor insulation grid, and belongs to the technical field of inductors.
Background
In the production and processing of the magnetic ring inductor, the winding coil and the inductor box need to be insulated and isolated; preventing the friction and the skin breakage between the enameled wire and the inductance box from causing the short circuit burn-in fault. Conventional insulation is achieved by using tape, with two layers wound around the winding coil. An isolation layer is formed on the coil, and a square film is placed at the bottom of the inductance box before the coil is placed in the inductance box, so that an isolation effect is achieved.
The isolation scheme has the following problems: the adhesive tape needs to be wound on two layers of coils, so that the processing time is long, the cost is high, and the production efficiency is low; the wound coil is heavy, and the product has the risk of falling due to the loss of hands in the wrapping process; the wound coil is heavy and can cause wrist injury after long-time wrapping; the circular film placed at the bottom of the inductance box is not easy to center, and once the circular film deviates, the enamel wire skin can be worn to cause short circuit.
A foldable annular inductor insulating protective film is mentioned in patent 2022203956591, which plays a role in isolating and protecting between an inductor and an inductor box. When the inductor works, heat is generated in the inductor coil because of the magnetic material loss of the magnetic core and the copper resistance loss of the winding coil, the voltage endurance capacity, the mechanical strength and the effective service life of the insulating material are reduced due to the increase of the temperature of the inductor, and even the phenomenon of burn-in occurs. Therefore, the inductor is placed inside the inductor box, and then the heat conducting silica gel is filled and sealed, so that the purpose is to rapidly transfer the heat generated by the inductor to the inductor box through the heat conducting silica gel to be emitted. Although the insulating film can be used for starting insulation, the heat dissipation effect is greatly reduced. Because this patent scheme uses the polyester film to wrap up the inductor completely, reaches the purpose of keeping apart with the inductance box, so the heat of inside need conduct to the polyester film when giving off, and then conduct to the heat conduction glue, finally conduct to the inductance box through the heat conduction glue (the heat conduction glue does not play direct heat conduction and connects the purpose of inductor and inductance box, has well spaced the polyester film). Since the thermal conductivity of the polyester film is very low, but only 0.2W/mK, the thermal conductivity of the thermal conductive silica gel is 1.0W/mK, so the thermal conductive effect is greatly reduced.
