Abstract
The utility model discloses a filter port coupling tuning mechanism. The filter port coupling tuning mechanism comprises an adjusting nut, a tuning cover plate and an adjusting block. The adjusting nut passes through the tuning cover plate and enters the cavity of a filter; a spring is arranged between the adjusting nut and the adjusting cover plate; the spring is fixed on the adjusting cover plate; and the adjusting block and the lower end of the adjusting nut are fixedly connected. The advantages are as follows: the installation debugging is simple, the coupling amount of a port can be changed according to different bandwidth performance requirements of the filter under the condition that the cover plate is not dismounted, the consistency is good, the production efficiency is improved, and the cost is reduced.
Description
Technical field
The utility model belongs to the band pass filter field for communication system base station, is specifically related to a kind of port of wave filter coupling tuning mechanism.
Background technology
Along with the development of the communication technology, communication standard, frequency range are more and more, and more and more higher to the module miniaturization in system, integrated requirement, a product needed is supported the performance requirement of different frequency range, different bandwidth.
For the filter of different frequency range, different bandwidth, coupling amount between resonance frequency, resonator, the coupling amount of port all need to accomplish tunable, the above two tuning methods is quite ripe and varied, tuning common way for port coupling amount need to be taken filter cover board apart, change height and the tap shape of feed, thereby reach desirable port coupling amount, but the method significantly affecting production efficiency, increase cost, and the consistency of port of wave filter coupling is difficult to ensure card.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of device of conveniently adjusted port of wave filter coupling amount, to enhance productivity, reduces production costs.
For achieving the above object, the utility model has adopted following technical scheme:
One port of wave filter coupling tuning mechanism, comprises adjusting nut, tuning cover plate and regulating block, adjusting nut enters in filter cavity through tuning cover plate, between adjusting nut and adjusting cover plate, be provided with shell fragment, shell fragment is fixed on and regulates on cover plate, and regulating block is fixedly connected with the lower end of adjusting nut.
As the further optimization of such scheme, described regulating block is shaped as rectangle, cylindrical or hexagonal cylindricality.
The beneficial effects of the utility model main manifestations is: its Installation and Debugging are simple, can, in the situation that not tearing cover plate open, change the coupling amount of port according to the performance requirement of filter different bandwidth, and high conformity, has improved production efficiency, has reduced cost.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model one embodiment.
Fig. 2 is that the utility model one embodiment is applied in the structural representation in filter.
Wherein 1 is regulating block, the 2nd, and adjusting nut, the 3rd, tuning cover plate, the 4th, connector, the 5th, dress resonant column screw, the 6th, resonant column, the 7th, filter cavity, the 8th, cover screw, the 9th, shell fragment.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, the utility model is done more specifically to describe.
As illustrated in fig. 1 and 2, one port of wave filter coupling tuning mechanism, comprise adjusting nut 2, tuning cover plate 3 and regulating block 1, adjusting nut 2 enters in filter cavity 7 through tuning cover plate 3, between adjusting nut 2 and adjusting cover plate 3, is provided with shell fragment 9, and shell fragment 9 is fixed on and regulates on cover plate 3, regulating block 1 is fixedly connected with the lower end of adjusting nut 2, and described regulating block 1 is shaped as cylindrical.
In the present embodiment, mainly go deep into the next tuning different port coupling amount of the degree of depth of filter cavity 7 inside by regulating block 1, the shell fragment 9 being fixed on tuning cover plate 3 cooperates secured adjusted piece with adjusting nut 2.
In Fig. 2, this radio-frequency unit comprises a base station integrated filter, one is installed on joint connector above of tuning cover plate 34, port resonant column 6 and a mechanical tuning device as shown in Figure 1, the mechanical tuning device of the present embodiment is between joint connector 4 and port resonant column 6, change the coupling amount of port by regulating adjusting nut 2 to adjust the degree of depth that regulating block 1 gos deep into filter cavity 7, determine coupling amount afterwards by adjusting nut 2 on tuning cover plate 3 and shell fragment 9 by fixing regulating block 1.
Be understandable that; for those of ordinary skills; can be equal to replacement or be changed according to the technical solution of the utility model and utility model design thereof, deduce other combining structure, and all these changes or replacement all should be belonged to the protection range of the utility model claim.
