RF coaxial connector

The innovation relates to an RF coaxial connector with a coaxial cable in an outer conductor sleeve arranged inner conductor rod and with at least one for supporting and centering the inner conductor rod Insulating body provided in the outer conductor sleeve.

V \ [ From DE-PS 647 15-3, DE-AS 1 204 294 and DE-PS 1 640 711 insulating material bodies are already known which serve to support and center inner conductors with respect to an outer conductor surrounding the inner conductor in a sleeve-like manner and in which only webs extend between the inner conductor and outer conductor, so that a relatively low-material support body is obtained, which hardly disturbs the homogeneity of the HF line. However, the known support bodies are designed so that the inner conductor can slide out of the grip of the support body. An absolutely safe centering of the inner conductor in the outer conductor is not guaranteed.

The task of the present innovation is therefore to provide an RF coaxial connector of the type mentioned in such a way that with the least possible material design of the insulating body nevertheless reliable centering and support of the inner conductor rod in the outer conductor sleeve is achievable.

According to the innovation, this problem is solved by that as an insulating body a ring-like completely enclosing the rod and resting on the rod

The flat sides 6 of the webs 5 extend parallel to the axis 7 of the inner conductor bar 1. The length of the webs in the radial direction is dimensioned so that the webs 5 with their free ends 8 on the outer conductor sleeve 9 support.

The inner conductor rod 1 is thereby reliably centered in the outer conductor sleeve 9 and that of the layer and the webs 5 forms existing insulating material only a minor disturbance in the course of the inner conductor bar 1 and the outer conductor sleeve 9 RF coaxial line.
