Abstract

The embodiment of the invention discloses a cavity filter. The cavity filter comprises a cavity body, a cover plate and an in-connector conductor, wherein the in-connector conductor is arranged in the cavity body and passes through the cavity body or the cover plate to connect a signal transfer point of an external circuit board of the cavity filter; the in-connector conductor comprises an elastic part; and the elasticity function of the elastic part is used for eliminating the relative position error between the in-connector conductor and the signal transfer point of the circuit board, ensuring good contact between the in-connector conductor and the signal transfer point of the external circuit board of the cavity filter, and avoiding the deformation damage of the circuit board in an installation process.

Description
