Description
Technical Field
The utility model relates to the technical field of electrical elements, in particular to a foldable annular inductance insulation protective film.
Background
In the production and processing of the magnetic ring inductor, the winding coil and the inductance box need to be insulated and isolated, so that the phenomenon that the enameled wire and the inductance box are rubbed and broken to cause short circuit and burn-in faults is prevented. The traditional insulation isolation uses adhesive tapes, two layers of adhesive tapes are wound outside a winding coil to form an isolation layer on the coil, and a square film is placed at the bottom of an inductance box before the coil is placed in the inductance box, so that an isolation effect is achieved. This isolation measure has the following problems: the adhesive tape needs to be wound on the coil by two layers, so that the processing time is long, the cost is high, and the production efficiency is low; circular film that inductance box bottom was placed is difficult for centering, in case the skew can cause the wearing and tearing of enameled wire skin to lead to the short circuit.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a foldable annular inductance insulation protective film which can effectively play a role in isolation and protection between an inductor and an inductance box, and is simple in process, low in cost and convenient to operate.
In order to achieve the purpose, the annular inductance insulation protection film capable of being formed in a folding mode comprises a wall film I, a wall film II and a bottom film, wherein the wall film I and the wall film II are identical in size and are rectangular, the bottom film is circular, the bottom film is located between the wall film I and the wall film II, and the wall film I and the wall film II are parallel; the left side and the right side of the bottom membrane are respectively connected with the middle parts of the wall membrane I and the wall membrane II integrally; the size of the bottom film is matched with the size of the bottom of the annular inductor; the lengths of the wall film I and the wall film II are more than half of the perimeter of the bottom film; the widths of the wall films I and II are matched with the height of the annular inductor.
Further, the material of the protective film is polyester or polyimide.
The utility model has the beneficial effects that: the three part of protection film, wall membrane I, wall membrane II use basement membrane and wall membrane I, wall membrane II's tie point to stand up upwards as the bending point, and wall membrane I, wall membrane II encircle into tubbiness each other, place annular inductance wherein, its compare with prior art, there are following advantages: the production efficiency is high, compared with the traditional adhesive tape and a pad film, the operation working hour can be saved, and particularly, the working hour is saved more remarkably for the production of inductors in large batch; the material cost is low, and compared with the traditional combined wrapping process of a film and an adhesive tape, only one protective film is needed; the reliability is better, but folding forming's inductance insulation protection film adopts 0.1mm thickness PET or PI material, keeps apart the inductor all around with the partial complete of inductance box contact, and the shaping back is indeformable, not squint, and insulating effect is better.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in figure 1, the ring-shaped inductance insulation protective film capable of being folded and formed is characterized in that a protective film 1 is composed of a wall film I11, a wall film II12 and a bottom film 13 and is formed by cutting a protective film raw material. The wall film I11 and the wall film II12 are same in size and are rectangular, the bottom film 13 is circular, the bottom film 13 is positioned between the wall film I11 and the wall film II12, and the wall film I11 is parallel to the wall film II 12. The left and right sides of the bottom film 13 are respectively connected with the middle parts of the wall film I11 and the wall film II12 integrally. The size of the bottom film 13 matches the size of the bottom of the toroidal inductor 2. The length of the wall film I11 and the wall film II12 is more than half of the circumference of the bottom film 13. The widths of the wall films I11 and II12 match the height of the toroidal inductor 2.
The protective film 1 with the structure takes the connection points of the wall film I11, the wall film II12 and the bottom film 13 as bending points, and then the wall film I11 and the wall film II surround to form a barrel shape, as shown in fig. 2, the annular inductor 2 can be placed when the protective film is used, the sizes can ensure that two sides of the wall film I and two sides of the wall film II are overlapped, the bottom film 13 can be just placed in the annular inductor, and the heights of the wall film I11 and the wall film II12 are consistent with the height of the annular inductor 3.
As shown in fig. 3 and 4, during production and assembly, the protective film 1 is placed on the inductance box 3, the toroidal inductor 2 is placed, the toroidal inductor 2 presses the bottom film 13 and sinks to the bottom of the inductance box 3, two sides of the protective film 1 are naturally folded and formed to form a completely wrapped protective film cavity, the toroidal inductor 2 and the inductance box 3 are completely isolated, and therefore the effect of protecting insulation is achieved. The material of the protective film 1 is polyester or polyimide.
The protection film 1 formed in a folding mode is simple in structure, convenient to operate, time-saving, labor-saving, high in reliability, low in cost, easy to popularize and apply and high in practical value.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes which can be made within the knowledge of those skilled in the art without departing from the gist of the present invention are within the scope of the claims of the present invention.
