  • Publication number: 20040104787
    Abstract: A filter assembly for use in the CATV industry includes a circuit formed by components mounted upon at least one circuit board with a plurality of paths or traces on the board connecting each section of the circuit to a member at ground potential. The grounding member may be a grounding bus on the circuit board which is in contact with a housing wherein the circuit board is mounted, or the paths may extend from a circuit component to contact the housing directly. The paths are kept to a very short length, preferably not more than 2.5 millimeters and in no case longer than 5 millimeters. This avoids the presence of inductive and/or resistive parasitics in the paths, thereby avoiding the degradation of performance typical in comparable prior art filter circuits, particularly at higher frequencies, e.g., above about 300 MHz. In the preferred embodiment grounding buses in the form of elongated strips extend along opposite edge portions of the board.

  • Patent number: 6733336
    Abstract: The present invention provides a connector used to interconnect a hard-line coaxial cable to an equipment port. The connector of the present invention essentially comprises a main connector body in which the various connecting and sealing members are housed, and a compression body attached to the connector body for axial, sliding movement between first and second terminal positions relative to the connector body. The port side of the connector includes a conductive pin extending axially outwardly therefrom that is adapted to be inserted into the port provided in the equipment box, and an axially extending bore is formed though the distal end (cable side) of the connector and compression bodies for receiving the central conductor of the hard-line cable therein.

  • Patent number: 6106333
    Abstract: A connector for making a non-linear connection between a female-type electrical receptacle and a coaxial cable having a male pin-type end connector includes a body defining an internal cavity therein and defining first and second passages that extend into the cavity. The cavity is elongate and defines a longitudinal axis along which an elongate conductor is disposed in the cavity, the conductor having a pin-receiving hole aligned with the first passage such that a pin-type end connector inserted into the first passage can engage the hole in the conductor. The conductor has a portion that extends through the second passage and projects out from the body and defines a pin for insertion into a female-type receptacle.
