A radio frequency coaxial connector (simply referred to as an RF connector) is generally considered to be a component attached to a cable or mounted on an instrument as a component to which a transmission line is electrically connected or separated. It belongs to a mechatronic product. In brief, it mainly acts as a bridge. A common type of rf coaxial connector, which has been widely used in communication equipment and the like, includes a receptacle and a plug that are inserted into each other, and generally the receptacle has a single elastic contact, while the receptacle has a single outer conductor, and the elastic contact of the receptacle makes 360 ° contact with the outer conductor of the plug to form a single electrical signal path. However, although such a single signal channel can conduct an electrical signal, it cannot achieve multi-channel electrical signal conduction in a narrow space, and thus cannot achieve miniaturization of the cabinet. In addition, even if the integration of multiple signal channels is realized, it is necessary to solve the problem that the rf coaxial connector or the PCB circuit board is damaged due to the different axes generated when the plug is mated with the receptacle, i.e., the mating of multiple signal channels.
