Patent ID: 8043117

Claim:
A coaxial plug connector comprising an outer conductor part, an inner conductor part, a dielectric which holds the inner conductor part within and coaxial with the outer conductor part at a predetermined axial position, and a plug-side end for plugged electrical and mechanical connection of the inner conductor part and the outer conductor part to a respective inner conductor part and outer conductor part of a complementary coaxial plug connector, wherein the dielectric has an axial channel with a predetermined first radial diameter within which the inner conductor part is arranged, at or spaced apart from the plug-side end of the dielectric, the first radial diameter of the channel tapers in the direction of the plug-side end from the first predetermined radial diameter to a second predetermined radial diameter, wherein the inner conductor part has at least one first diameter and one second diameter smaller than the first diameter and smaller than the second predetermined radial diameter of the channel of the dielectric, wherein the first diameter of the inner conductor part is chosen so that the inner conductor part fits within the first predetermined radial diameter of the channel and simultaneously, the first diameter of the inner conductor part is larger than the second predetermined radial diameter of the channel, forming a shoulder at an outer side of the inner conductor part at the point at which the first diameter of the inner conductor part gives way to the second diameter of the inner conductor part, wherein said shoulder is arranged at the outer side of the inner conductor part in the axial direction such that the inner conductor part is situated at the predetermined axial position within the outer conductor part when the shoulder of the inner conductor part rests against the taper of the radial diameter of the channel of the dielectric, having at least one elevation provided on an outer side of the inner conductor part and, on an inner side of the dielectric which faces toward the channel, at least one recess is arranged and configured such that the elevation on the inner conductor part locks with the recess in the dielectric when the inner conductor part is pushed axially into the channel of the dielectric as far as the predetermined axial position.
