Patent ID: 7484997

Claim:
A coaxial plug-in connector for fitting to a coaxial cable, the coaxial plug-in connector comprising: an inner conductor part having an outer periphery, and including N detent hooks with N greater than or equal to 2 on said outer periphery, said detent hooks spaced apart from each other evenly in peripheral direction; an outer conductor part; and an insulating part including an axial through-hole for passing through the inner conductor part, wherein said through-hole includes an edge dividing said through-hole in the axial direction into a first section with a first diameter and into a second section with a second diameter which is greater than the first diameter, the first diameter being smaller and the second diameter being greater than the outer periphery of the inner conductor part which is defined by outer surfaces of the detent hooks on a respective maximum radial elevation thereof, that in addition the insulating part has on its periphery 2n+(N−1) recesses with n greater than or equal to 1, said recesses spaced apart from each other evenly in the peripheral direction, and overlap respectively both the first section and the second section of the through-hole in the axial direction and are formed such that the wall of the through-hole is able to be deflected radially outwards elastically in the region of each recess.
