Abstract
The invention discloses a filter shell body, comprising a first shell body, a second shell body and a heat radiation sheet; the first shell body and the second shell body are connected; a round of inner wall is arranged in the first shell body; the inner wall and the wall of the first shell body form an inserting slot; first jacks are symmetrically opened on the wall of the first shell body close to the bottom surface; first joint holes are arranged at the upper parts of the first jacks; second jacks are symmetrically opened on the inner wall close to the bottom surface; the second jacks are opened on the face corresponding to the first jacks; second joint holes are arranged at the upper parts of the second jacks; third jacks are symmetrically opened on the second shell body close to the bottom surface; and third joint holes are arranged at the upper parts of the third jacks. Through the mode, according to the filter shell body of the invention, the filter shell body is unnecessarily fixedly connected by a nut; the space occupied by the filter product is reduced; meanwhile, the assembly efficiency is improved; and the production cycle of the product is shortened.
Description
Technical field
The present invention relates to a kind of electric elements, particularly relate to a kind of casing of filter.
Background technology
Filter is that one is passed through undamped as far as possible for useful signal, to the radio-frequency devices that unwanted signal is decayed as far as possible; Generally be located at signal transmitting and receiving device or the circuit part of communication equipment, to realize the selection index system of communication device signal.
Usually, filter is primarily of filter cavity and cover plate composition, be provided with multiple resonant rod in filter cavity, it is relative with described resonant rod that tuning screw one end penetrates cover plate, by the distance between adjustment means adjustment tuning screw and resonant rod to reach required radio-frequency (RF) index.
Need above cover plate during installation to stay certain space to give prominence to the part of cover plate for holding described nut, pad and tuning screw, the space causing whole filter product to take increases, and then cause the space of whole radio system also to increase, during manual assembly, should assembling nut, assemble pad again, greatly reduce the efficiency of assembling of product, thus extend life cycle of the product.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of casing of filter.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of casing of filter, comprising: the first housing, the second housing and fin, and described first housing is connected with described second housing;
A circle inwall is provided with in described first housing, a slot is formed between the wall of described inwall and described first housing, on the wall of described first housing, close bottom surface place symmetry offers the first jack, described first jack top is provided with the first nipple orifice, on the face that on described inwall, close bottom surface place is corresponding with described first jack, symmetry offers the second jack, described second jack top is provided with the second nipple orifice, described second housing offers the 3rd jack near bottom surface place symmetry, 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 a preferred embodiment of the present invention, the wall of described second housing matches with described slot.
In a preferred embodiment of the present invention, described first jack, described second jack and described 3rd jack are in same level.
In a preferred embodiment of the present invention, the height of described inwall is lower than the height of the wall of described first housing.
In a preferred embodiment of the present invention, the difference in height of the wall of described inwall and described first housing is the thickness of described second housing end face.
In a preferred embodiment of the present invention, described first nipple orifice, described second nipple orifice and described 3rd nipple orifice match.
