CAVITY FILTER WITH CONNECTING STRUCTURE CONNECTED BETWEEN SLIDER AND DRIVING DEVICE

摘要

A cavity filter includes a slider, a driving device, and an adapter. The slider is used to slide relative to and couple with a plurality of resonators located in the cavity filter to adjust a resonating frequency of the cavity filter. The driving device is used to drive the slider slide relative to the plurality of resonators and includes a shaft having a free end. The adapter is installed between the slider and the driving device and rotateably connected to the free end of the shaft with a gap configured between the free end and the adapter.

1. A cavity filter, comprising:
a slider, sliding relative to and coupled with a plurality of resonators located in the cavity filter to adjust a resonating frequency of the cavity filter; a driving device, driving the slider to slide relative to the plurality of resonators, the driving device comprising a shaft parallel to the slider, the shaft comprising a free end; and an adapter, installed between the slider and the driving device and rotateably connected to the free end of the shaft with a gap configured between the free end and the adapter, the gap absorbing vibrations of the free end, allowing the slider to move on an even keel during adjustment of the resonating frequency.
