Embodiment

For reaching above-mentioned purpose and effect, the purpose that the utility model adopted, technical feature of structure with and effect, the existing drawing explains in detail that with regard to the preferred embodiment of the utility model its characteristic and function are following, understand in order to do profit fully.

See also Fig. 1 and shown in Figure 2, be the modular filter structure three-dimensional exploded view and the profile of the utility model.The modular filter structure of present embodiment includes an insulation shell 1; Three groups of

splicing ears

21,22,23; Four filter coils 31; And four chip type filter elements 32.Yet the utility model can comprise many group splicing ears, a plurality of filter coil, reach a plurality of chip type filter elements, is not limited to above-mentioned quantity.

Insulation shell 1 is when one-body molded; Be provided with in regular turn first fixed wall 11, second fixed wall 12 and the 3rd fixed wall 13 of arranging, and be separated out at first accommodation space 15 between this first fixed wall 11 and this second fixed wall 12 and second accommodation space 16 between this second fixed wall 12 and the 3rd fixed wall 13.
