[0003] Patent document CN218828285U discloses an inner conductor, a coaxial cable and a microwave device, belonging to the field of microwave transmission. The inner conductor includes a first inner conductor, a second inner conductor and an internal elastic member.

The internal elastic member is arranged in the recess, and the two ends of the internal elastic member are connected with the first inner conductor and the second inner conductor respectively. The elastic force of the internal elastic member makes the mating end face of the first inner conductor abut against the mating end face of the second inner conductor. The coaxial cable includes an outer conductor, a dielectric layer and an inner conductor. The outer conductor, the inner conductor and the dielectric layer are connected by two independent parts, and the connection part can swing around the axis, so that the entire coaxial cable can absorb a certain amount of torsional deformation, thereby avoiding deformation or damage of the inner conductor under the action of torsional force. Moreover, the above design does not affect the transmission performance of the coaxial cable.
