Description

Technical Field

[0002] Radio frequency coaxial connector (hereinafter referred to as RF connector) is generally considered to be a component installed on a cable or installed on an instrument, as a component for electrical connection or separation of transmission lines. It belongs to mechatronics products. Simply put, it mainly plays a bridging role. Compared with other electronic components, the development history of RF connectors is relatively short. The UHF connector that appeared in 1930 was the earliest RF connector. During the Second World War, due to the urgent needs of the war, with the development of radar, radio stations and microwave communications, medium-sized series such as N, C, BNC, TNC were produced. After 1958, miniaturized products such as SMA, SMB, SMC appeared. In 1964, the US military standard MIL-C-39012 "General Specification for Radio Frequency Coaxial Connectors" was formulated. Since then, RF connectors have begun to develop in the direction of standardization, serialization and generalization.

[0003] However, the connectors currently in use cannot be used in the marine environment, which has high temperatures, high humidity, strong corrosion from seawater splashing and salt spray, long sunshine hours, high solar radiation, and frequent typhoons. Most of the current assembly structures are gap fits, and the gaps are prone to water ingress when used in humid areas, outdoors, or underwater environments. The entire cable assembly may not work properly or may cause a risk of short circuiting the equipment or impurities or excess material may enter the product. In addition, current RF cable assemblies are subject to repeated bending and dragging, and the core wires in the core-shooting coaxial connectors are prone to axial shrinkage, which may easily cause the RF cable assembly to have a risk of poor contact with its matching connector.
