High power radio frequency connector capable of quickly locking and separating

Abstract

The present invention relates to a high power radio frequency connector capable of quickly locking and separating, a plug comprises a fixing ring, a collar, a sheath, a back-up ring, a large spring, asmall spring, a thread sleeve and a housing, the back-up ring is pressed and arranged on the housing, the thread sleeve connects the plug integrally, locking steel balls are evenly distributed in a circumferential hole of the fixing ring, outer side contacts with the sheath, and inner side contacts a bevel A on the collar, the large spring is mounted on inner side of the back-up ring, and the small spring is mounted on outer side of the back-up ring, the pre-pressure of the large spring is higher than that of the small spring, the sheath presses the locking steel balls in the fixing ring under press of the large spring and the small spring, a part pressing the locking steel balls at front end of the collar comprises the bevel A and a bevel B, and grooves are provided at front end of the butt joint interface of the socket. The invention has advantages of small butt joint locking force and separation unlock force, rapid butt joint and locking; large interface maintenance force, convenient locking and separation, high reliability, excellent mechanical and electrical property.

Description

technical field [0001] The invention belongs to the technical field of electrical connectors, and relates to a connection mechanism with fast locking and separation functions. The connection mechanism is mainly used in the field of high-power radio frequency connectors, especially for high-power radio frequency connectors. Background technique [0002] High-power RF connectors, because of their large size and high third-order intermodulation index, currently have threaded locking structures. Through this threaded connection, the plug and the socket are pressed against each other to ensure the coincidence of their electrical reference planes. For example, in the products disclosed in patents such as US5088937, DE3117320, and EP0867978A2, threaded connection locking methods are respectively adopted. Through this threaded connection, the plug and the socket are pressed against each other to ensure the coincidence of their electrical reference planes. This connection and lockin...

AI Technical Summary

Problems solved by technology

This connection and locking method has at least the following defects: 1) It cannot be quickly plugged and unplugged, and the docking and separation are quite laborious, and the assembly efficiency is low; 2) A minimum distance for placing assembly tools must be left between the plug and the plug, and the installation density is low. , cannot be arranged in high density

[0003] The RF coaxial connectors described in patents such as CN 1185765C and other patents solve the above two problems well, but they are limited to low-power signal transmission
