Abstract
The utility model discloses a cross coupling metal sheet for a TE mode dielectric filter. The cross coupling sheet metal for the TE mode dielectric filter comprises two side wings and a metal sheet between the two side wings. The shape of the middle metal sheet is formed by digging a structure shaping like a Chinese character "ao" in the middle of the bottom of a structure shaping like a Chinese character "tu". The two side wings are in the same shape which is formed by removing a half horizontal stroke of a Chinese character "gong" at the top left corner and a horizontal stroke of the Chinese character "gong" at the bottom right corner. One end of each of the two side wings is vertically connected to each of the two sides of the middle metal sheet. The other end of each of the two side wings has a certain radian. The cross coupling metal sheet can enable a cross coupling metal component to be fixed more stably, and the cross coupling metal sheet is prevented from rotating.
Description
Technical field
The utility model relates to the microwave filter in wireless communication field, is specifically related to a kind of TE mould dielectric filter cross-couplings sheet metal.
Background technology
Develop rapidly along with wireless communication technology, operator is more and more higher to the performance requirement of filter, the TE mould dielectric filter of high Q value is widely used, can adopt simultaneously and there is the precipitous cross-couplings technology with external characteristic, generally with the cross-linked form of three chamber cross-couplings or four chambeies, be used as element circuit, in order to produce the outer transmission zero of required band, cross-couplings assembly must cut electromagnetic field, coupling metal parts need to TE mould medium periphery carry out around, if middle fixed mechanism adopts copper rod, the in the situation that of vibrations, pole can rotate, thereby destruction electric property.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide a kind of TE mould dielectric filter cross-couplings metal parts of being convenient to more effectively fix.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A mould dielectric filter cross-couplings sheet metal, comprises two flanks and two sheet metals that flanks are middle, and described intermediate metal film is shaped as and in the middle of the bottom of " protruding " font structure, cuts out a formed shape of " recessed " font; Two described flanks are same shape, for " work " word removes half horizontal stroke in the upper left corner and the half horizontal formed shape in the lower right corner, the both sides of the sheet metal in the middle of one end of two described flanks is vertically connected to, the other end of two described flanks has certain radian.
As the further optimization of such scheme, the surface of described sheet metal is coated with layer of metal copper or aluminium, prevents oxidized.
As the further optimization of such scheme, the other end cover of two flanks of described sheet metal has heat-shrinkable T bush, after described compression sleeve heating, can dwindle, and is then close on cross-couplings sheet metal.
The beneficial effects of the utility model main manifestations is: in TE mould dielectric filter, adopt cross-couplings sheet metal of the present utility model, make cross-couplings metal parts fixing more stable, prevent that cross-couplings sheet metal from rotating, and provides a kind of cross coupling structure of simple stable TE mould dielectric filter.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model will be further described.
As shown in Fig. 2,3 and 4, a kind of TE mould dielectric filter cross-couplings sheet metal 11 in the present embodiment, comprise two flanks 15 and two sheet metals 16 that flanks are middle, described intermediate metal film 16 is shaped as and in the middle of the bottom of " protruding " font structure, cuts out a formed shape of " recessed " font; Described two flanks 15 are same shape, for " work " word removes half horizontal stroke in the upper left corner and the half horizontal formed shape in the lower right corner, the both sides of the sheet metal 16 in the middle of one end of two described flanks 15 is vertically connected to, the other end of two described flanks 15 has certain radian.
The surface of described cross-couplings sheet metal 11 is coated with layer of metal copper or aluminium.
The other end cover of two flanks of described sheet metal has heat-shrinkable T bush 12, after described compression sleeve 12 heating, can dwindle, and is then close on cross-couplings sheet metal 11.
For making above-mentioned cross-couplings sheet metal 11 obtain stable fixing, the utility model has adopted following fixture: a kind of fixture of TE mould dielectric filter cross-couplings sheet metal 11, comprise insulation support body the first half 9 and insulation support body the latter half 10, described insulation support body the latter half 10 is a cuboid, the face of two opposition of described cuboid is provided with same draw-in groove 13, in the middle of cuboid one side perpendicular to draw-in groove 13 directions, be provided with the groove 4 of " fourth " font, opposite with the cuboid one side of the groove 4 of " fourth " font is also provided with draw-in groove 13, draw-in groove 13 in two described opposites is rectangular-shaped, the degree of depth sum of two draw-in grooves 13 is less than the thickness perpendicular to the cuboid one side of draw-in groove 13 directions, described insulation support body the first half 9 is identical with insulation support body the latter half 10, like this, when making insulating supporting mould, only needs a mould, provides cost savings and the time.
While using the utility model in actual conditions, first installing and being coupled on the breach 3 on chamber wall 2 with the aspectant draw-in groove in fluted place insulation support body the latter half 10, then by the intermediate metal film of cross-couplings sheet metal 11, the ledge near heat-shrinkable T bush 12 vertically embeds in the groove 4 of insulation support body the latter half 10, and then insulation support body the first half 9 is coupled to intermediate metal film 16 another ledges of cross-couplings sheet metal 11 by groove 4.
By using the cross-couplings sheet metal 11 of the present embodiment to coordinate with corresponding fixture, can prevent from being looped around the defect that TE mould medium sheet metal around rotates, simple in structure, easy to operate, reliable and stable.
By reference to the accompanying drawings the utility model preferred implementation is explained in detail above, but the utility model is not limited to above-mentioned execution mode, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.
