Low intermodulation RF coaxial connector

Abstract

The invention relates to the field of cable connector, which is use to solve the technical problem to provide low intermodulation radio frequency coaxial connector. The material of inner and outer positive connector is antimagnetic brass; the material of conductor of negative connector is beryllium copper or tin bronze; the material of connector of conductor of negative connector is antimagnetic brass, and the material of connector of conductor of positive connector is antimagnetic brass; the plating coats of outer conductor metal part of negative positive connector are copperized silverplating plating ternary alloy, and the plating coats of inner conductor metal part of negative positive connector are silverplating, and the component of said ternary alloy, copper: 50%-65%, tin: 30-45%, zinc: 5-10%. The invention can improve the three-level intermodulation property of product, and when the radio frequency coaxial connector matches with corresponding radio frequency coaxial cable, the single channel communication system can have great physical property and electricity property, and it with low intermodulation index can used in multi-channels communication system.

Description

Technical field: [0001] The invention relates to the field of cable connectors, in particular to a radio frequency coaxial connector. Background technique: [0002] RF coaxial connectors are used in the radio frequency circuits of military equipment and radio electronic instruments. They play the role of connecting coaxial cables or electronic equipment and transmitting electrical performance. They are indispensable components in radio frequency circuits. [0003] As shown in Figure 1, a complete set of radio frequency coaxial connectors is composed of a male connector 10 and a female connector 20. The structures of the male connector 10 and the female connector 20 correspond to each other. The outer conductor and the inner and outer conductors of the female connector can be closely connected to each other to achieve reliable electrical contact. The inner conductor of the male connector is generally a pin type, and the inner conductor of the female connector is generally mad...
