Problems solved by technology

Antennas, antennas and feeders between antennas and equipment are exposed to space and are vulnerable to lightning strikes. The existing technology generally prevents lightning pulses from invading radio equipment from antennas and antenna feeders by installing independent lightning arresters, and installing independent lightning arresters requires lightning protection. The transfer between the equipment, the arrester and the antenna feeder cable will inevitably cause transmission loss, and at the same time increase the total investment of the equipment; at the same time, the magnetic field generated by the existing arrester when it is turned on will affect the surrounding electronic components In order to prevent this effect, a shielding protective shell is usually set up. The shielding protective shell traditionally used is made of metal, but it has many shortcomings such as high density and poor corrosion resistance, which cannot meet the increasing demand for electromagnetic shielding materials in modern society. high requirements

Abstract

The invention discloses a radio frequency connector with lightning protection function, which comprises a radio frequency connector body, a lightning protection device and a cable connector sequentially connected from left to right; Body and lightning protection circuit; the outer surface of the lightning protection device is equipped with a shielding protection shell, and the lightning receptor is installed outside the shielding protection shell; the shielding protection shell is made of electromagnetic shielding material; the electromagnetic The shielding material is prepared by mixing modified epoxy resin and metal foam. The invention connects the lightning protection device with the radio frequency connector and the cable connector to form a radio frequency connector with lightning protection function. The radio frequency connector not only has the function of convenient connection and reduced installation, but also has a reasonable structure and strong practicability , to avoid unnecessary damage caused by work in lightning weather conditions.

Description

technical field [0001] The invention relates to the field of radio frequency connectors, in particular to a radio frequency connector with lightning protection function. Background technique [0002] RF connector cable assembly is a widely used connection between radio equipment and between equipment and antennas. It is understood that various existing RF connector cable assemblies are composed of RF connectors and cables, which only have connection functions and no anti-corrosion Thunder function. Antennas, antennas and feeders between antennas and equipment are exposed to space and are vulnerable to lightning strikes. The existing technology generally prevents lightning pulses from invading radio equipment from antennas and antenna feeders by installing independent lightning arresters, and installing independent lightning arresters requires lightning protection. The transfer between the equipment, the arrester and the antenna feeder cable will inevitably cause transmissio...
