Abstract

The present invention relates to a dual-end floating coaxial radio frequency adapter. A semi-flexible coaxial line is connected between two radio frequency plug terminals at two ends of the adapter, the semi-flexibility of the semi-flexible coaxial line can meet the axial and radial floating requirements, the features of the semi-flexible coaxial line determines that the semi-flexible coaxial linecan meet the phase consistency which must be met by the adapter, the inner and outer conductors of the semi-flexible coaxial line are electrically connected with an inner conductor module and an outer conductor of the two radio frequency plug terminals, radio frequency signals can be transmitted in a thickness-equal insulation medium between the inner and outer conductors of the semi-flexible coaxial line, the equal distance between the inner and outer conductors of the semi-flexible coaxial line can be achieved depending on the insulation layer in an annular so that the problem of impedancechange caused by varying of cross sections is avoid, the voltage standing wave is good, and the transmission quality of the radio frequency signals is greatly improved.

Description

technical field [0001] The invention relates to a double-end floating coaxial radio frequency adapter. Background technique [0002] At present, the connection mode of the intermediate transfer part of various double-ended floating adapters is mainly a pin-hole-to-plug structure to achieve floating, such as figure 1 Shown is a structural diagram of a common double-ended floating adapter, in which the two sections of the inner conductor in the middle are connected through jacks and pins to achieve floating connection, and the outer conductor is also a combined plug-in structure. The mechanical floating structure of the conductor causes the cross-sectional size between the inner conductor and the outer conductor to change in the axial direction. The medium between the inner and outer conductors is used to transmit signals. Different cross-sections will cause different impedances for signal transmission, and impedance changes It leads to the change of voltage standing wave rat...
