Radio frequency connector interface structure

Abstract

The embodiment of the invention discloses a radio frequency connector interface structure. The connector comprises a plug connecting end and a socket connecting end. The plug connecting end comprisesa plug inner conductor and a plug outer conductor wrapping the plug inner conductor. The plug inner conductor comprises a first contact section a second transmission section and a third reinforcing section in which the diameters are gradually increased, a conical structure of the first contact section realizes effective contact with a socket connecting end; the plug outer conductor comprises a connecting front part, a convex fixing part and an extending tail part in sequence corresponding to the plug inner conductor; a sealing ring is arranged between the connecting front part and the convex fixing part, an inclined guide block used for preventing deformation of an opening of the socket connecting end is arranged at the connecting position of the convex fixing part and the extending tail part, and the connecting front part, the convex fixing part and the extending tail part wrap the outer surface of the second transmission section and the outer surface of the third reinforcing sectionrespectively. According to the scheme, by optimizing the interface structure, the wall thickness of the outer conductor reaches 0.4 mm, and the problem of reliability caused by too small interface wall thickness of SSMC series connectors is solved.

Description

Technical field [0001] The embodiment of the present invention relates to the technical field of radio frequency connectors, in particular to an interface structure of a radio frequency connector. Background technique [0002] Modern electronic system equipment is becoming more and more miniaturized. SSMC series connectors are mainly used for small space and low RF signal transmission and insertion. This series of products can be applied to the military connector market. [0003] SSMC series radio frequency connectors have a plug screw socket with a hexagonal size of 4mm, which is only 50% of the SMA connector commonly used in the market (the screw socket has a hexagonal size of 8mm), and is a miniaturized SMA product commonly used in the market. The hexagonal size of the screw sleeve is 62.5% of 6.4mm. It has the advantages of small size and light weight. [0004] However, due to its small size, it also brings the reliability of the SSMC series of RF connectors. The wall thicknes...
