Embodiment Construction

[0020] The present invention will be further described below through embodiments in conjunction with the accompanying drawings.

[0021] An embodiment of the present invention is as figure 1 The three-dimensional diagram of the press-fit radio frequency coaxial connector is shown. The coaxial connector is composed of a dielectric body 3 , an inner conductor 2 , a metal boss base 5 , a dielectric pressing block 1 , a fastening screw 6 and a metal cover plate 4 . A semicircular groove is opened on the metal boss base 5 and embedded in the dielectric body 3 . The dielectric body 3 retains the part embedded in the base of the metal boss, and the rest is cut off, which is semicircular after cutting. The inner conductor 2 is embedded in the dielectric body, and the lower half of the U-shaped groove formed on the inner conductor 2 is embedded in the semicircular dielectric body. The height of the U-shaped groove is slightly greater than the thickness of the core material of the comp...

Abstract

The invention discloses a radio frequency coaxial connector crimped and connected with a composite material strip line, belongs to the technical field of radar antenna feeders, and solves the problems of easy assembly and reliable connection with the composite material strip line. The radio frequency coaxial connector includes a dielectric body, an inner conductor, a metal boss base, a dielectric pressure block, fastening screws and a metal cover, wherein a semicircular groove is opened on the metal boss base, and a semicircular groove is embedded in the groove. medium body. The inner conductor in the coaxial connector has a U-shaped groove and is embedded in a semicircular dielectric body. The height of the groove is slightly greater than the thickness of the stripline interlayer printed board made of composite material. The coaxial connecting body fastens the metal cover plate, medium pressure block, composite material strip line, and metal boss base through fasteners to realize crimping connection. When the invention is connected with the strip line waveguide, welding operation is avoided, and the assembly is simple and convenient. The invention can be widely used in radar and communication systems, and is especially suitable for lightweight antenna feeder systems based on composite materials.

Description

technical field [0001] The invention belongs to radar antenna feeder technology. Background technique [0002] The existing composite material stripline structure (a stripline of PMI foam dielectric board with low loss and lightweight structure, patent application number: 201711293021.7) consists of shielding layer, PMI foam board, printed board, PMI foam board, shielding layer Composition, due to the soft texture of PMI foam, it brings great difficulties to the reliable connection of the RF coaxial connector and the structure. [0003] The existing RF coaxial connector structure is usually for printed board stripline (a semi-coaxial microstrip combined RF transmission line structure, patent application number: 201910657732.0) or air dielectric stripline form. For composite material striplines, the inner conductor of the coaxial connector needs to conduct simultaneously with the upper and lower metal layers of the printed board sandwich to effectively transmit radio frequen...
