A non-floating blind-mate RF coaxial connector

Abstract

The invention discloses a floating-free and blind-mating type radio-frequency coaxial connector. The floating-free and blind-mating type radio-frequency coaxial connector comprises a plug connector and a socket connector, wherein head ends of the plug connector and the socket connector are respectively used as inserting ends; two plug casings are mounted on a plug flange; a first plug insulator, a second plug insulator and a pin contact element are all mounted in each plug casing; the head end of each plug casing is provided with a convex punching-packaging structure; two socket casings are mounted on a socket flange; a first socket insulator, a second socket insulator and a jack contact element are all mounted in each socket casing; an inner casing is mounted at the head end of each socket casing; a flared hole is formed in the head of each inner casing; the tail of each flared hole is in smooth transition with an inner hole of the corresponding inner casing. The working frequency of the floating-free and blind-mating type radio-frequency coaxial connector can reach 10GHz; by adopting a floating-free and blind-mating structural design, axial and radial malalignment can be automatically corrected within a certain range; the floating-free and blind-mating type radio-frequency coaxial connector has the characteristics of high reliability, vibration resistance and wide temperature region resistance; meanwhile, requirements on miniaturization and high-power transmission are met.

Description

technical field [0001] The invention belongs to the technical field of electronic information, in particular to a non-floating blind mating type radio frequency coaxial connector. Background technique [0002] A radio frequency connector is a component used in the radio frequency range, usually mounted on a cable or mounted on a system module. The connector is installed in the system and plays the role of power transmission and radio frequency signal transmission. In the ground environment, the radar equipment modules can be plugged and unplugged in multiple ways at the same time, so as to facilitate quick installation and disassembly. Due to the size and weight requirements of the system, the space of the module structure is limited, the connector needs to be miniaturized, and high-power radio frequency signals need to be transmitted in the connector. [0003] At present, the working interfaces of quick-plug RF connectors used in China can be listed in order of size from ...

AI Technical Summary

Problems solved by technology

SMP, SBMA and BMA RF connectors have low power capacity and cannot meet the requirements of the user system for the power capacity of the connector

The TMA type connector is a floating blind mating structure with large dimensions, which is difficult to meet the multi-channel high-density installation requirements in the user's specific space.

In addition, when the TMA-type connector is installed with a large number of channels, it will generate a force of more than several hundred Newtons on the mounting plate, which may cause deformation and distortion of the mounting plate.

The SBX type RF connector has a large power capacity, but the connector has a large size, low integration, and excessive weight, which cannot meet the requirements of miniaturization and high integration.
