Filter port connecting structure

The invention discloses a filter port connecting structure which comprises a cavity, a port structural body is installed in the cavity, a resonator is installed on the port structural body, the resonator is located in the cavity, a cover plate is installed on the top of the cavity, a connector base is installed on the top of the cover plate, a connector is installed in the connector base, and the connector is located in the cavity. The connector is provided with a connector PIN, the connector PIN is wrapped with an insulating sleeve, and the bottom of the connector PIN is inserted into the port structure body. The structure of the cavity can be directly used for conducting signals, the number of parts is reduced, and cost is reduced; meanwhile, the port does not need to be welded, the connector PIN needle can be directly inserted into the port structure body to form capacitive coupling, and the connector PIN needle is used for conducting signals, so that the welding risk is avoided, and the stability and the
