Novel anti-rotation sealed connector

Abstract

The invention discloses a novel anti-rotation sealed connector which comprises an inner conductor, an outer conductor and an insulator, wherein grooves are respectively radially arranged on the inner conductor, the outer conductor and the insulator, seal rings can be clamped into the grooves for completing sealing, anti-rotation barb and a fixed barb a are arranged on the outer diameter of the inner conductor, an anti-displacement barb is arranged on the outer diameter of a channel a, a fixed barb b is arranged on the bottom end surface of the channel a, and straight knurling is processed on the surfaces of the inner diameter and the outer diameter of the inner conductor as well as the inner diameter of the outer conductor, so that anti-rotation and sealing effects can be achieved and sealing performance can be thoroughly improved.

Description

technical field [0001] The invention relates to a connector, in particular to a novel anti-rotation sealed connector. Background technique [0002] The radio frequency coaxial connector is an electromechanical component mounted on the cable or installed on the instrument, which plays the function of transmission, electrical connection or separation, and is an indispensable key component of the coaxial transmission system. The current RF connectors have good broadband transmission characteristics and a variety of convenient connection methods, making them more and more widely used in satellite, radar, wireless and wired communications, aviation, aerospace and navigation. At present, there are high requirements for the structure, design, electrical, mechanical, environmental and other performance of RF connectors. In some special occasions (such as outdoor base stations, high temperature and high humidity environments, etc.), it is also required The lower mechanical propertie...

Problems solved by technology

Nowadays, connectors that only use a single rubber sealing ring at the electrical and mechanical interface to achieve the sealing effect have a high failure rate in high-low temperature and high-pressure environments, especially for high-power connectors.

The axial displacement and torsional risk of the inner conductor are also relatively high. It often occurs that the inner conductor is affected by the stress to cause axial floating when the product is installed on the device and exposed to the outside or aging, and the radial gap between the insulator and the outer conductor shrinks due to temperature changes. or expand to leak
