Plate-to-plate concentration mounting type RF coaxial connector

Abstract

The invention discloses a plate-to-plate intensive assemblage coaxial connector, comprising two sockets and a commutator. A first flange and a second flange with different axial lengths are arranged on the peripheral planes of the two ends of the commutator; a groove is arranged on the side wall at the bottom of the opening of the socket; when the commutator is inserted into the socket, the first flange is located in the groove, the second flange clings to the inner side wall of the corresponding socket opening. Because the first flange, the second flange and the groove matching the first flange are provided, the plugging and pulling forces become varied, the commutator is left on one of the circuit boards when being pulled away, thereby, the operation time is saved and ineffective plugging and pulling actions reduced; in addition, the lockup between the shells is used to largely increase the plugging and adapting frequency. By taking advantage of the clearance between the commutator shell and the insulator thereof, the commutator deviates in the opening upon incorrect medium condition, as a result, the position is corrected automatically and the purpose of direct plugging and adapting is achieved.

Description

technical field [0001] The invention relates to a coaxial connector, in particular to a high-density mounting type radio frequency coaxial connector applied between printed circuit boards. Background technique [0002] At present, with the development of communication technology, the volume of various military and civilian microwave communications, mobile communications and precision testing instruments tends to be miniaturized and miniaturized. For this reason, higher requirements are put forward for the coaxial connectors used in these devices, especially the high-density mounted radio frequency coaxial connectors between circuit boards. [0003] A general coaxial connector is composed of a plug male connector (abbreviated as a plug) and a socket female connector (abbreviated as a socket). Most of the existing common coaxial connectors use threaded connectors or quick-plug connectors. Among them, the threaded connector is to connect the screw sleeve by screwing, so that i...

AI Technical Summary

Problems solved by technology

However, after careful analysis of the structure of the above-mentioned coaxial connector, it is found that: (1) The flanges at both ends of the outer conductor of the male connector have the same structure, and they are all inserted directly into the opening of the corresponding female connector shell. The locking between the connectors is realized by the cooperation between the curved inner cavity of the insulator and the spherical surface of the insulator, but due to the influence of the insulating material, it is easy to wear between the curved inner cavity of the insulator and the spherical surface of the insulator. The connector will be damaged under the number of mating times, that is, its service life is short

(2) Since the insulators and insulators of the female and male connectors need to be processed into spherical surfaces, this will cause inconvenience in processing and high overall cost

(3) There is an expansion joint on the inner conductor of the male connector, so that it has a certain degree of elasticity, so that although the contact performance with the inner conductor of the female connector is better, it will intensify the wear between the two at the same time

(4) Due to the different inner surface structures at both ends of the male connector insulator, it is necessary to install female connectors with different structures on each circuit board, which limits its use to a certain extent.

However, the above phenomenon will undoubtedly increase the workload of the operator, and it will take time and effort to plug and unplug, making the work efficiency low; Its working reliability and service life
