Abstract: The present disclosure provides a plug connector, including: a mounting plate including a first side having an electrical component area; a first electrical component cavity and a second electrical component cavity arranged in the electrical component area; a first electrical component arranged in the first electrical component cavity and a second electrical component arranged in the second electrical component cavity. The plug connector further includes a groove, a sealing ring arranged in the groove and a fixing plate arranged on the first side, wherein the sealing ring is arranged between the fixing plate and the mounting plate. The plug connector can provides a waterproof function during a floating insertion of a mating connector.

Abstract: Disclosed is a circular filter assembly, relating to the field of wireless communication. The circular filter assembly includes: a dielectric filter and a dielectric waveguide circulator. The dielectric waveguide circulator is provided with at least three end portions. An end of the dielectric filter is connected to one of the end portions. A cascade matching window is disposed at a connection between the dielectric filter and the end portion, and the cascade matching window is used for adjusting impedance of the circular filter assembly. The dielectric waveguide circulator and the dielectric filter are integrally formed. By integrally forming the dielectric waveguide circulator and the dielectric filter, connecting members between the dielectric waveguide circulator and the dielectric filter can be reduced. In addition, the cascade matching window is added to perform impedance adjustment, to obtain the same standing wave indicator as a conventional connection using a connector.
