In this way, the utility model relates to a wave filter casing, this wave filter casing need not the nut and carry out fixed connection, have reduced the space that the wave filter product occupy, have improved assembly efficiency simultaneously, have shortened product production cycle.
Description
Technical field
This utility model relates to a kind of electric elements, particularly relates to a kind of casing of filter.
Background technology
Wave filter is that one is passed through the most undamped for useful signal, the radio-frequency devices decayed garbage signal as far as possible；Typically it is located at signal transmitting and receiving device or the circuit part of communication equipment, to realize the selection of communication device signal.
Generally, wave filter is mainly made up of filter cavity and cover plate, being provided with multiple resonant rod in filter cavity body, it is relative with described resonant rod that tuning screw one end penetrates cover plate, by the distance between regulation instrument regulation tuning screw and resonant rod to reach required RF index.
The part staying certain space to highlight cover plate for accommodating described nut, pad and tuning screw is needed above cover plate during installation, the space causing whole wave filter product to take increases, and then cause the space of whole radio system also to increase, during manual assembly, nut should be assembled, assemble pad again, greatly reduce the efficiency of assembling of product, thus extend life cycle of the product.
Utility model content
This utility model is mainly solving the technical problems that provide a kind of casing of filter.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: a kind of casing of filter, including: the first housing, the second housing and fin, described first housing is connected with described second housing；
A circle inwall it is provided with in described first housing, a slot is formed between four walls of described inwall and described first housing, symmetrical at the bottom surface on four walls of described first housing offer the first jack, described first jack top is provided with the first nipple orifice, on face corresponding with described first jack at bottom surface on described inwall, symmetry offers the second jack, described second jack top is provided with the second nipple orifice, described second housing is symmetrical at bottom surface offers the 3rd jack, and described 3rd jack top is provided with the 3rd nipple orifice；
Described fin runs through described first jack, described second jack and described 3rd jack.
In one preferred embodiment of this utility model, four walls of described second housing match with described slot.
In one preferred embodiment of this utility model, described first jack, described second jack and described 3rd jack are in same level.
In one preferred embodiment of this utility model, the height of described inwall is less than the height of four walls of described first housing.
In one preferred embodiment of this utility model, the thickness that difference in height is described second housing end face of four walls of described inwall and described first housing.
In one preferred embodiment of this utility model, described first nipple orifice, described second nipple orifice and described 3rd nipple orifice match.
In one preferred embodiment of this utility model, described fin matches with described first jack, described second jack and described 3rd jack.
The beneficial effects of the utility model are: this utility model one casing of filter, and this casing of filter is fixedly connected without nut, decrease the space that wave filter product takies, improve efficiency of assembling simultaneously, shorten life cycle of the product.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of casing of filter of this utility model.
In accompanying drawing, the labelling of each parts is as follows: 1, the first housing；2, the second housing；3, fin；4, inwall；5, slot；6, the first jack；7, the second jack；8, the 3rd jack；9, the first nipple orifice；10, the second nipple orifice；11, the 3rd nipple orifice.
Detailed description of the invention
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus protection domain of the present utility model is made apparent clear and definite defining.
Referring to Fig. 1, this utility model embodiment includes: a kind of casing of filter, including: the first housing the 1, second housing 2 and fin 3, described first housing 1 is connected with described second housing 2.
It is provided with a circle inwall 4 in described first housing 1, the height of described inwall 4 is less than the height of four walls of described first housing 1, the thickness that difference in height is described second housing 2 end face of four walls of inwall 4 described in the present embodiment and described first housing 1 so that described first housing 1 is smooth with described second housing 2 upper surface when mounted.
Forming a slot 5 between four walls of described inwall 4 and described first housing 1, four walls of described second housing 2 match with described slot 5, and described slot 5 is for described first housing 1 and the connection of described second housing 2 and fixes.
Symmetrical at the bottom surface on four walls of described first housing 1 offer the first jack 6, on face corresponding with described first jack 6 at bottom surface on described inwall 4, symmetry offers the second jack 7, described second housing 2 is symmetrical at bottom surface offers the 3rd jack 8, described first jack 6, described second jack 7 and described 3rd jack 8 are in same level so that described fin 3 can preferably pass described first jack 6, described second jack 7 and described 3rd jack 8.
Described first jack 6 top is provided with the first nipple orifice 9, described second jack 7 top is provided with the second nipple orifice 10, described 3rd jack 8 top is provided with the 3rd nipple orifice 11, and described first nipple orifice 9, described second nipple orifice 10 and described 3rd nipple orifice 11 match, for erection joint.
Described fin 3 runs through described first jack 6, described second jack 7 and described 3rd jack 8, described fin 3 matches with described first jack 6, described second jack 7 and described 3rd jack 8, described fin 3 has not only acted as the effect of heat radiation, has simultaneously worked as fixing described first housing 1 and the effect of described second housing 2.
Compared with prior art, this utility model one casing of filter, this casing of filter is fixedly connected without nut, decreases the space that wave filter product takies, improves efficiency of assembling simultaneously, shorten life cycle of the product.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in scope of patent protection of the present utility model.
