Coaxial shunt and current detection system

A coaxial shunt, configured to measure a high-frequency current signal in an assisted manner, comprising:

• an outer conductor, an accommodating cavity being formed inside the outer conductor;
• a resistor body, received in the accommodating cavity;
• a central shaft conductor, the outer conductor, the resistor body, and the central shaft conductor each being of cylindrical structures and coaxially arranged from outside to inside, the center shaft conductor penetrating through the outer conductor, and both ends of the resistor body being electrically connected to the outer conductor and the center shaft conductor, respectively;
• and
• an insulating filler, arranged in the accommodating cavity to fill gaps among the outer conductor, the resistor body, and the center shaft conductor, wherein
• an insulating connector is arranged between the outer conductor and the central shaft conductor, and the insulating connector is mechanically connected to both the outer conductor and the center shaft conductor to fix relative positions between the center shaft conductor and the outer conductor, and transfers an external force of the center shaft conductor received to the outer conductor;
• and/or the center shaft conductor and the resistor body are flexibly electrically connected to buffer the external force of the center shaft received.
