Patent ID: 8414327

Claim:
A coaxial connector extending along a longitudinal axis, the coaxial connector comprising: a body that is oriented along the longitudinal axis; and a central contact mounted in the body with interposition of insulation positioned in the body, wherein the insulation comprises three distinct portions: a front portion, a rear portion, and a middle portion connecting between the front portion and the rear portion along the longitudinal axis of the coaxial connector, the front, middle and rear portions being made of different dielectric materials, a first interface between the front portion and the middle portion of the insulation presents at least a fraction that extends obliquely relative to the longitudinal axis of the coaxial connector, a second interface between the middle portion and the rear portion of the insulation presents at least a fraction that extends obliquely relative to the longitudinal axis of the coaxial connector; both the fraction of the first interface that extends obliquely relative to the longitudinal axis and the fraction of the second interface that extends obliquely relative to the longitudinal axis, being not collinear with electric field lines that extend radially within the coaxial connector, avoid creating avalanches of electrons in a vacuum and also avoid accumulating charge at the first interface and the second interface; and a portion of the insulation, in particular the rear portion of the insulation, is configured to exert a holding action on an insulation of a coaxial cable which is mounted into the rear portion and the central contact.
