Abstract

The invention discloses a high-voltage coaxial cable joint and aims to solve the problem that an existing high-voltage coaxial cable joint is likely to cause sparks when large current flows and is inaccurate to connect and position. The high-voltage coaxial cable joint consists of a cable male connector and a cable female connector. The connection reliability is improved by disposing a metal spring on the contact surface of the cable male connector and the cable female connector. The positioning accuracy is improved by installing an auxiliary positioning ring on the outer insulator of a high-voltage coaxial cable. Thus, the overall connection effect of the high-voltage coaxial cable joint is improved. The high-voltage coaxial cable joint realizes the high-voltage potential contact betweenthe inner conductor connecting body and the female connecting body of the cable male connector, and the elastic connection of the ground potential contact between a male connector nut and a female connector flange, so as to avoid partial contact in case of eccentric installation . The high-voltage coaxial cable joint solves the sparks when the pulsed large current flows, enhances a connection effect, and is suitable for high-voltage coaxial cables of different radial sizes, and is improved in universality.

Description

technical field [0001] The invention relates to the technical field of high-power pulse driving sources, in particular to a high-voltage coaxial cable joint. Background technique [0002] The needs of national defense and industrial applications have prompted the development of high-power pulse drive source technology in the direction of solid-state and modularization. These applications include high-power microwaves, high-power pulsed lasers, material surface treatment, industrial waste gas and wastewater treatment, and food sterilization and disinfection. The use of high-voltage coaxial cables to realize the connection between solid-state modules can provide convenient conditions for module debugging and device integration; therefore, the development of high-voltage coaxial cable matching connectors with excellent performance is of great significance to the debugging and operation of the device . The single-core or multi-core connectors of the existing high-voltage cables...
