Cavity filter and connecting structure included therein

A cavity filter, comprising:

• a filter body;
• a terminal insertion port provided in the filter body as a hollow space;
• and
• a terminal portion, provided in the terminal insertion port, and is configured to electrically connect an electrode pad, provided above the filter body, to an RF (radiofrequency) signal connector which is spaced apart from the electrode pad and provided below the terminal insertion port,
• wherein the terminal portion comprises a cylinder-shaped terminal body,
• wherein a first end of the terminal portion is in contact with the electrode pad, and a second end of the terminal portion, provided on an opposite side of the first end, is coupled to the RF signal connector, and
• wherein the terminal body comprises at least one cut out portion formed on a side wall of the terminal body,
• wherein the cavity filter further comprises an insertion slot support portion which protrudes from a wall of the terminal insertion port to support a bottom surface of the terminal body, and
• wherein the cavity filter further comprises a reinforcement plate supported by the insertion slot support portion, and the reinforcement plate supports at least a part of a lower surface of the terminal body.
