Quick-blind-mating floating-type-mounted RF coaxial connector and connecting method thereof

Abstract

The invention discloses a quick-blind-mating floating-type-mounted RF coaxial connector and a connecting method thereof. The RF coaxial connector comprises a socket and a plug. The socket comprises an inner conductor jack, an insulator, a socket outer conductor, a floating sleeve, a spring and a mounting panel. The plug comprises a plug outer conductor, an inner conductor inserting pin, an elastic collar and a mounting board. The elastic collar is connected with an engaging trough in an adapted engaging manner. The inner hole linear section of the socket is in insertion fit with the outer cycle linear segment of the plug. According to the RF coaxial connector, on the condition that the plug is inserted into the socket, two reference surfaces are superposed, thereby forming a theoretical zero clearance and ensuring continuity of capacitance. Furthermore a specific engagement structure is utilized, thereby eliminating radial clearance and preventing axial endplay clearance in a stationary state in insertion. Furthermore the quick-blind-mating floating-type-mounted RF coaxial connector and the connecting method have advantages of small size, compact structure, low reflection coefficient, low voltage standing wave, full-band linear voltage standing-wave ratio, excellent shielding efficiency, etc.

Description

technical field [0001] The invention relates to a radio frequency coaxial connector, in particular to a radio frequency coaxial connector with fast blind insertion and floating installation and a connection method. Background technique [0002] Coaxial connectors can be roughly divided into threaded, bayonet, push-in and other types according to the way of plug and socket connection. The push-in floating installation coaxial connector, due to the advantages of quick plug-in, floating blind plug, and modular intensive installation, has developed BMA type and OSSP type since its inception. Dozens of well-known companies such as Tyco in the United States, Radiall in France, and Huber+Suhner in Switzerland have developed quick-plug, floating RF coaxial connectors. Among them, Tyco of the United States, Radiall of France, and Huber+Suhner of Switzerland have an annual supply volume of more than 2 million sets, and have been successfully used in various military weapon systems an...

AI Technical Summary

Problems solved by technology

[0004] The frequency of use of the push-in floating installation coaxial connector is not high, the BMA type is 18GHz, the OSSP type is 28GHz, and the electrical performance is relatively poor (radio frequency leakage, voltage standing wave ratio)

It can only meet the use requirements of general civilian equipment, and cannot be used in modern communication high-tech equipment

At present, connectors with working frequency in the millimeter wave band are basically limited to thread mechanism connectors, such as APC3.5 series, APC2.4 series, SK series, and 1.0 series; Not high enough to achieve fast blind mating and modular floating installation
