Millimeter wave coaxial connector with novel insulating support structure

Abstract

The invention discloses a millimeter wave coaxial connector with a novel insulating support structure. An insulating medium support is a circular solid sheet; the side face of the insulating medium support is provided with a notch; an inner hole is formed in the center of the insulating medium support; a groove is formed on a central conductor; the outer diameter of the groove is the same as the diameter of the inner hole in the center of the medium sheet, and is slightly smaller than the outer diameters of other parts of the central conductor; the medium sheet is the same as the groove on the central conductor in thickness; the central conductor is pushed into the central position from the notch in the side face of the solid medium sheet, and two parts can be fixed together by using the groove; the medium sheet is clamped in a groove in the inner cavity of an outer conductor, so that the central conductor and the outer conductor keep coaxial with each other; the dielectric constant of a medium is reduced by forming an opening in the medium sheet, so that the using frequency is increased; and annular grooves are formed at the two ends of the medium sheet, so that electric transition between a solid medium and an air medium is realized. The method is a novel method for realizing the millimeter wave coaxial connector.

Description

Technical field [0001] The invention belongs to the field of microwave communication, and relates to a millimeter wave coaxial connector, particularly a millimeter wave coaxial connector realized by a novel insulator supporting structure. Background technique [0002] The radio frequency coaxial connector is an important transmission element in the microwave field. It has the characteristics of wide frequency bandwidth, convenient and reliable connection, superior performance, and low cost. It is widely used in microwave communication equipment, instrumentation and weapon systems. With the development of modern communication technology in recent years, the technical requirements for radio frequency coaxial connectors have become higher and higher. The millimeter wave coaxial connector is developed on the basis of the radio frequency coaxial connector. Although their design principles are similar, the millimeter wave connectors have high frequency of use, small size, and high pre...
