Definitions

  • the present invention relates to an improved antenna board assembly for facilitating the interconnection of 5 antenna and cable signals to the tuner section of a television receiver, and to improvements in wire receptacles and switches.
  • the VHF tuner of a television receiver is designed to receive unbalanced 75 ohm signals.
  • many antenna leads for broadcast receivers supply balanced 300 ohm signals. Consequently, television receivers intended for broadcast transmissions customarily include a so-called balun transformer connected between the antenna terminals and the VHF tuner for transforming balanced 300 ohm signals to unbalanced 75 ohm signals.
  • cable signals are normally unbalanced 75 ohm signals capable of being coupled directly to the VHF tuner. Adapting a particular receiver from one type of reception to the other normally requires a wiring change in the receiver or use of an additional coupling device or some other inconvenient modification. Similarly, when a television receiver is moved from place to place, the disconnection and connection of antenna leads from the commonly used screw terminals is an inconvenience.
  • connections are made between the tuner section, the balun transformer, and the antenna lead terminals. Further connections may be required if the receiver is designed to receive a cable signal.

Terminals of the cable connector are connected to conductors of a tuner cable extending from the board assembly to the television tuner section. Moreover, one of the cable terminals is provided with means for supporting the tuner cable.
  • circuit means including a switch is coupled between the tuner cable and wire receptacles for controlling the interconnection of the antenna leads with the tuner cable.
  • the circuit means includes a transformer, and transformer leads are attached by crimping to the spring terminals of the wire receptacles and to one of the switch terminals. The other switch terminal is crimped to a wire conductor leading to a terminal of the cable connector.
