What 3. this utility model passed through to alternate in mounting seat is provided for installing the installing hole of inductance and is used for
The mounting blocks of electric capacity are installed, so prevent two inductance from producing mutual interference signal, it is to avoid the stability of filter circuit is made
Become impact, electric capacity is installed between inductance so that the inner space that housing installed by wave filter is fully used so that filtering
The integrated level of device circuit is high so that the installing space that needs in a device of wave filter is little.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the front view of Fig. 1.
Fig. 3 is the structural representation of this utility model lid.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment further illustrates to the technical scheme in this utility model.
Referring to the drawings 1,2,3, this utility model includes installing housing and lid 1, installs housing by mounting seat 2 and fixing
Installation cylinder 3 in mounting seat 2 forms；Mounting seat 2 be circular plate structure, mounting seat 2 with diameter greater than mounting cylinder
The diameter of body 3, and mounting seat 2 with install cylinder 3 bottom surface the center of circle overlap；Mounting seat 2 is provided with for installing inductance
