Abstract

The invention discloses a polarity-variable confluence wire connector for transmitting pulse large current into a vacuum chamber, and relates to the field of pulse power electric energy transmission. Comprising two wiring terminals, a wiring terminal connecting rod, a variable connecting rod, a transition module and a busbar. The wiring terminal is a bridge for connecting a load coil in the vacuum cabin and a pulse current device outside the vacuum cabin; the busbar is used for converging the output current of each discharge module of the pulse large-current device and separating the current outflow end from the current return end of the coaxial cable; and the wiring terminal connecting rod, the variable connecting rod and the transition module are connected with the busbar and the wiring terminal, and are parts for realizing current polarity conversion at the same time. In a vacuum chamber with a relatively high vacuum degree, the confluence wire connector can be used as a connection bridge between a pulse large-current device outside the vacuum chamber and a load coil inside the vacuum chamber; output coaxial cables of all discharge modules of the pulse large-current device outside the vacuum cabin can be connected with input and output ends of a load coil in the vacuum cabin.
