Description
Technical field
The present invention relates to a kind of electric elements more particularly to a kind of casing of filter.
Background technique
Filter is a kind of by the useful signal RF device for passing through, decaying as far as possible to garbage signal as undamped as possible
Part；The general signal transmitting and receiving device or circuit part for being set to communication equipment, to realize the selection index system of communication device signal.
In general, filter is mainly made of filter cavity and cover board, multiple resonant rods, tuning are equipped in filter cavity body
It is opposite with the resonant rod that screw rod one end penetrates cover board, by adjust tool adjust the distance between tuning screw and resonant rod with
Reach required RF index.
It needs to stay certain space for accommodating the prominent cover board of the nut, gasket and tuning screw above cover board when installation
Part causes entire filter product the space occupied to increase, and then the space of entire radio frequency system is caused also to increase, artificial to fill
Timing should assemble nut, assemble gasket again, greatly reduce the assembly efficiency of product, to extend life cycle of the product.
Summary of the invention
The invention mainly solves the technical problem of providing a kind of casing of filter.
In order to solve the above technical problems, one technical scheme adopted by the invention is that: a kind of casing of filter, comprising: the
One shell, second shell and cooling fin, the first shell are connected with the second shell；
It is equipped with a circle inner wall in the first shell, forms one between the inner wall and four walls of the first shell and inserts
Slot, symmetrically offers the first jack on four walls of the first shell at bottom surface, and first jack top is equipped with the
One nipple orifice symmetrically offers the second jack on face corresponding with first jack at bottom surface on the inner wall,
Second jack top is equipped with the second nipple orifice, and the second shell symmetrically offers third jack, institute at bottom surface
Third jack top is stated equipped with third nipple orifice；
The cooling fin runs through first jack, second jack and the third jack.
In a preferred embodiment of the present invention, four walls of the second shell are matched with the slot.
In a preferred embodiment of the present invention, first jack, second jack and the third jack are same
On one horizontal plane.
In a preferred embodiment of the present invention, height of the height of the inner wall lower than four walls of the first shell.
In a preferred embodiment of the present invention, the difference in height of four walls of the inner wall and the first shell is described the
The thickness of two housing top surfaces.
In a preferred embodiment of the present invention, first nipple orifice, second nipple orifice and the third connector
Hole matches.
In a preferred embodiment of the present invention, the cooling fin and first jack, second jack and described
Third jack matches.
The beneficial effects of the present invention are: a kind of casing of filter of the present invention, the casing of filter are fixed without nut
Connection, reduces filter product the space occupied, while improving assembly efficiency, shortens life cycle of the product.
