Filter assembly

摘要

An object of the present invention is to provide an improved and simplified filter assembly. The object is achieved by a dielectric rod (120, 610, 620) for a filter chassis (110). The dielectric rod (120, 610, 620) extends between a first end (121) and a second end (122). The dielectric rod (120, 610, 620) comprises a conductive element (150) placed at the first (end 121). The conductive element (150) is adapted to be in conductive contact with a first contact means (141) of the filter chassis (110). The dielectric rod further comprises a second fastening element (160) placed at the second end (122). The second fastening element (160) is adapted to be attached and detached to a first fastening element (131) comprised in the filter chassis (110), such that the dielectric rod (120, 610, 620) is replaceable in the filter chassis (110).

1. A dielectric rod for a filter chassis, the dielectric rod extending between a first end and a second end of the dielectric rod, the dielectric rod comprising:
a conductive element placed at the first end, wherein the conductive element is adapted to be in conductive contact with a first contact of the filter chassis; and a second fastening element placed at the second end; wherein the second fastening element is externally threaded for releasably engaging a corresponding internally threaded first fastening element of the filter chassis, to releasably mate the dielectric rod to the filter chassis such that the dielectric rod is replaceable in the filter chassis; wherein the second fastening element comprises a projecting element; wherein a longitudinal axis of the dielectric rod extends through the second fastening element and the conductive element; and wherein the conductive element comprises a second projecting element that is tapered in a direction away from the first end.
