Abstract: Disclosed is a plug and receptacle connector arrangement for interconnecting a printed circuit board with a multi-conductor flat cable. The receptacle assembly includes terminals of the tuning fork type, and a housing which is mounted to an edge of a printed circuit board. The plug assembly includes a plurality of U-shaped channels having two parallel spaced-apart cable engaging walls joined by a common bight portion. One end of the bight portion comprises a plug terminal contact surface which is received by the tuning fork receptacle terminals. At the opposing end of the terminal, each wall cable engaging includes an insulation displacement termination portion for interconnection to the flat cable. Right angle and straight (in-line) embodiment of the invention are disclosed. The connector arrangement is particularly advantageous when used in a vibrating environment of an automobile or other moving vehicle.
