Document Type and Number:
WIPO Patent Application WO/2021/189788
Kind Code:
A1
Abstract:
The present invention relates to a novel SMA-type radio frequency coaxial connector, comprising a first housing, a connecting screw sleeve rotatably sleeved on the first housing, an inner conductor provided in the first housing, an insulation assembly for fixing the inner conductor in the first housing, a bushing provided in the first housing and located behind the inner conductor, and a second housing which is connected to a rear end of the first housing and is used for pressing the bushing into the first housing; the bushing comprises a bushing segment I and a bushing segment II which is formed by a rear end of the bushing segment I extending rearward in an axial direction of the connector, the inner diameter of the bushing segment I is less than the inner diameter of the bushing segment II, and welding through holes are respectively provided on the bushing segment I and the bushing segment II. When the connector is used for welding and assembling of a cable, an inner shield layer and an outer shield layer of the cable are respectively welded and fixed to the bushing segment I and the bushing segment II, greatly increasing the stability of the inner shield layer of the cable, being able to obtain a good electric performance index, the connector having a good high-frequency performance, and also being able to ensure the reliability of the connection.
