Abstract
The utility model relates to an isolation type multilayer coil. The isolation type multilayer coil comprises a first copper piece, an insulating film and a second copper piece, wherein the insulating film is disposed between the first copper piece and the second copper piece, and the insulating film pastes the first copper piece and the second copper piece by dry glue. The isolation type multilayer coil is capable of carrying large currents and simple in production process.
Description
Technical field
The utility model relates to magnetic element, relates in particular to a kind of isolated lattice coil.
Background technology
In the large electric current multi-turn product of exploitation, require small product size more and more less, also just need to satisfy under the equal current situation, use copper sheet to replace enamel-cover circle line, but use copper sheet the difficulty of multi-turn must occur making.
Therefore, how to provide a kind of and can carry large electric current, the simple isolated lattice coil of production technology is the problem that needs solve.
The utility model content
In order to solve the problems of the prior art, the utility model provides a kind of isolated lattice coil.
The utility model provides a kind of isolated lattice coil, comprise the first copper sheet, dielectric film and the second copper sheet, described dielectric film is arranged between described the first copper sheet and described the second copper sheet, and described dielectric film is by doing described the first copper sheet of glue and described the second copper sheet.
Isolated lattice coil provided by the utility model can carry large electric current and production technology simple.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use among the embodiment, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the constitutional diagram of the isolated lattice coil of the utility model.
Fig. 2 is the structure chart of the isolated lattice coil of the utility model.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is carried out clear, complete description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
Be illustrated in figure 1 as the constitutional diagram of isolated lattice coil.Wherein, figure (a) is the schematic diagram of the first copper sheet 10, and figure (b) is the schematic diagram of dielectric film 20, and figure (c) is the schematic diagram of the second copper sheet 30, and figure (d) is the first copper sheet 10, the second copper sheet 30 and the schematic diagram of dielectric film 20 by solder joint 50 welding.This isolated lattice coil comprises the first copper sheet 10, dielectric film 20 and the second copper sheet 30, and dielectric film 20 is arranged between the first copper sheet 10 and the second copper sheet 30, and dielectric film 20 is by dried glue 40(40 ') stickup the first copper sheet 10 and the second copper sheet 30.The center of the first copper sheet 10, dielectric film 20 and the second copper sheet 30 has the hole of formed objects.The pin side of the first copper sheet 10 has bending type the first long and narrow perforate.The pin side of the second copper sheet 30 has bending type the second long and narrow perforate.The first long and narrow perforate and the second long and narrow perforate are staggered.Dielectric film 20 has rectangular opening, and the area of rectangular opening is greater than the first long and narrow perforate and the second long and narrow perforate sum.The rectangular opening place of dielectric film in the present embodiment, uses filamentary silver with the short circuit means of spot welds as solder joint 50 spot welding.
Be illustrated in figure 2 as the structure chart of isolated lattice coil.The surface of this isolated lattice coil comprises high temperature gummed tape 60, is wrapped in the surface of the first copper sheet 10 and the second copper sheet 30.
Isolated lattice coil provided by the utility model relies on first tool fixture to use Instant cement with the individual pen copper sheet, dielectric film, and individual pen copper sheet bonding, and then use filamentary silver with the short circuit means of spot welds, use at last high temperature gummed tape that two circle copper sheets are coated.Use this scheme greatly to reduce the production difficulty of product, and improve the efficient of product, and reliability, can solve the copper sheet multi-turn and connect, and reduce the connection of product external windows position, so effective saving cost, reduce package dimension, and improve and produce line production efficiency, and product reliability.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model embodiment.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation of the spirit or scope that do not break away from the utility model embodiment, realize in other embodiments.Therefore, the utility model embodiment will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
It below only is the preferred embodiment of the utility model embodiment; not in order to limit the utility model embodiment; all within the spirit and principle of the utility model embodiment; any modification of doing, be equal to replacement, improvement etc., all should be included within the protection range of the utility model embodiment.
