Universal double-end connector for testing high-frequency filter device packaged by contact pin

The invention relates to a universal double-end joint for testing a pin-packaged high-frequency filter device. The universal double-end joint comprises an outer conductor, a first inner conductor and a second inner conductor, the outer conductor is in a circular tube shape, the first inner conductor and the second inner conductor are both circular tube-shaped components and are coaxially arranged at the two ends of the outer conductor respectively, and one end of the first inner conductor and one end of the second inner conductor are closed and abut against each other. The second inner conductor is coaxially provided with a jack at one end away from the first inner conductor, and the first inner conductor is coaxially provided with a jack or a pin at one end away from the second inner conductor. A first insulating medium is filled between the first inner conductor and the outer conductor, a second insulating medium is filled between the second inner conductor and the outer conductor, and the outer conductor,
