Abstract

The invention discloses a coaxial cable and an end part connecting method thereof which relate to the technical field of cable connection, and solve the problem that the conventional coaxial cable adopts an end part bifurcation connection leading-out mode, and a lead-out cable wire easily breaks at a bifurcation point due to the electromagnetic force under the condition of ultra-strong pulse current through-flow, so that the reliability of the cable is influenced. The main technical scheme of the present invention is that a connecting end part comprises a low-voltage connecting end and a high-voltage connecting end, the low-voltage connecting end comprises an outer conductor which is partially exposed and stripped from an inner insulating layer, and the high-voltage connecting end is a partially exposed inner conductor; an outer conductor snap ring comprises a first fixing sleeve ring and a first supporting sleeve ring, wherein the fixing sleeve ring sleeves the low-voltage connectingend, the outer conductor of the low-voltage connecting end is connected between the first fixing sleeve ring and the first supporting sleeve ring in a pressing mode, and the outer conductor of the low-voltage connecting end is electrically connected with the first fixing sleeve ring.

Description

technical field [0001] The invention relates to the technical field of cable connection, in particular to a coaxial cable and an end connection method thereof. Background technique [0002] A coaxial cable refers to a cable that has two concentric conductors, and the conductor and shield share a single axis. The most common coaxial cable consists of copper conductors separated by insulating material, on the outside of the inner insulating material is another layer of ring conductor and its insulator, and then the whole cable is covered by a sheath of PVC or Teflon material . Generally, coaxial cables are used for the transmission of ultra-high power pulse energy under high voltage and high current conditions. The coaxial cable is mainly confined between the inner and outer conductors due to the armored outer conductor in the form of a wrapped central conductor. , so the external electromagnetic interference is small, and it is mainly used in the field of pulse power in som...
