Embodiment 1

[0013] refer to figure 1 , in an embodiment of the non-contact radio frequency coaxial connector described below, the non-contact connector has a metal cylinder 1 with an open end and a small hole at the bottom of the other end, the opening surface of the metal cylinder 1 A piece of metal sheet 3 smaller than the opening size of the metal cylinder is placed. The metal sheet 3 is not in direct contact with the inner wall of the metal cylinder 1. The size of the metal sheet 3 will vary according to the working frequency of the coaxial RF connector and the metal cylinder. Size is adjusted, the metal sheet 3 is connected with a metal wire 2 leading to the bottom of the metal cylinder 1, usually this metal wire 2 can be straight or curved, and the metal wire 2 passes through the metal cylinder 1 The small hole at the bottom constitutes a coaxial transmission line structure, and the connection device 6 that is convenient to connect with the coaxial cable or other electromagnetic wav...

Embodiment 2

[0015] refer to figure 2 , in an embodiment of the non-contact radio frequency coaxial connector described below, the non-contact radio frequency coaxial connector has a structure similar to that of Embodiment 1, the difference is that the central inner wire 2 is connected in series The inductance or capacitance 7 with concentrated parameters is mentioned. As for the choice of inductance or capacitance in the specific scheme, and the determination of the value depends on the requirements for the operating frequency, bandwidth, and size of the connector.

Abstract

An embodiment of the invention discloses a forming scheme of a non-contact radio-frequency coaxial connector which can be used in the communication field, and can also enable radio-frequency signals in a coaxial transmission system to be interconnected and intercommunicated under the condition of not needing conductor direct mechanical contact. When one end of the non-contact radio-frequency coaxial connector adopting the scheme is connected with a coaxial cable or other microwave circuits such as microstrip lines and strip lines and the like, and the other end serving as a connection end face is close to and connected with another non-contact radio-frequency coaxial connector assembled in the same way, even if inner and outer metal conductors forming the two connectors are not in direct electrical contact, the transmission lines at the two sides or the radio-frequency signals of the circuit are allowed to realize mutual transmission through the two non-contact radio-frequency coaxial connectors. Compared with the contact radio-frequency connector frequently used at present, the non-contact radio-frequency coaxial connector is better in reliability and weatherability, and more convenient to use in field projects.

Description

technical field [0001] The present invention relates to a transmission mode of electromagnetic wave signals in the technical field of communication, and in particular relates to a radio frequency coaxial connector capable of interconnection and intercommunication of electromagnetic wave signals without direct physical contact of conductors. Background technique [0002] In electronic systems and electronic equipment, people use radio frequency coaxial cables extensively to communicate high-frequency signals between equipment and equipment, modules and modules, and equipment and modules, and the connections between cables and these equipment modules are mostly through radio frequency Connectors are implemented. [0003] The RF coaxial connectors currently used by people, such as N-type connectors, SMA connectors, etc., are all contact RF connectors, that is, the inner and outer conductors of the two coaxial connectors to be connected need to be mechanically mated. Stable rad...
