Abstract

The invention discloses an air-tightness joint with double female ends which comprises an inner conductor at the center, an insulating medium coaxially sleeved outside the inner conductor, and an outer conductor with a stepped hole type inner cavity. The insulating medium is arranged in the stepped hole of the outer conductor and is coaxially arranged together with the outer conductor; a fixing block is connected to an opening part of a stepped hole of the outer conductor in a close fit manner; the fixing block and the step surface of the stepped hole form axial limitation at two ends of the insulating medium. The air-tightness joint with double female ends has a simple structure, good air tightness, strong environment tolerance, reliable mechanical performances, excellent electric performances and high assembling efficiency, and is suitable for production on a large scale.

Description
