  • Patent number: 5404276
    Abstract: An RFI through-let for screening signals transmitted between different components, for instance circuit boards, of which one component is arranged in a screened space, includes signal-transmission through-let capacitors which are mounted in a screen plate intended to be positioned in a rectangular opening in the side-wall of the screened space. The screen plate is comprised of a front part which includes a rectangular, generally flat plate having tongues or tabs disposed along the sides thereof and also having a central, rectangular hollow, and a holding part which is soldered firmly in the vicinity of the hollow of the front part. The holding part includes a flat plate whose long sides are bent to form guide flanges which extend perpendicularly downwards away from the front part, along a first line corresponding to the long sides of the opening, and along a second line downwardly of the first line are further bent inwardly towards one another.

  • Patent number: 5329066
    Abstract: A coaxial cable through-let for screening signals transmitted between two mutually adjacent, screened spaces includes a coaxial cable having electrical contact devices at each end thereof for signal transmission, and a screening plate which surrounds the cable and which is intended to be positioned between the two spaces in recesses provided in mutually facing side-walls thereof. The screening plate comprises two substantially identical plate-halves, each of which includes a flat, rectangular plate having resilient tongues disposed along three sides thereof, and a centrally placed hollow, wherein the heights of the hollows correspond to half the distance between the spaces. An opening for accommodating the coaxial cable is arranged centrally in the hollow, and the two plate-halves are soldered together at their mutually facing hollows and also in the opening at the screen of the coaxial cable at a part from which the cable sheath has been stripped.
