Abstract

In printed circuit technology, tri-lead cables are used to interconnect among signal pins on the wiring side of a circuit board for making circuits complete which cannot be imbedded in the printed circuitry. They are also used to make engineering changes and to upgrade a board in the field. The tri-lead cable consists of one signal conductor and two ground conductors that are encapsulated in a dielectric material to provide the desired impedance. The connector portion consists of a tuning fork contact connected to the signal conductor and another tuning fork contact connected to the two ground conductors.

Connector Extraction Device

In printed circuit technology, tri-lead cables are used to interconnect among signal pins on the wiring side of a circuit board for making circuits complete which cannot be imbedded in the printed circuitry. They are also used to make engineering changes and to upgrade a board in the field. The tri-lead cable consists of one signal conductor and two ground conductors that are encapsulated in a dielectric material to provide the desired impedance. The connector portion consists of a tuning fork contact connected to the signal conductor and another tuning fork contact connected to the two ground conductors. The tuning fork contacts and the end portions of the conductors to which they are connected are removably retained in a pluggable housing which facilitates the plugging of the tuning fork contacts onto the signal pins and ground rails on the circuit board.

Damage to a signal pin or to the tuning fork contacts, or making an engineering change, or upgrading the circuit board, may call for the removal of the tri-lead cable from the housing. The tuning fork contacts have barbs on their ends which latch onto ledges inside the housing. It becomes essential that the tuning fork contacts be unlatched and the cable removed from the housing without any damage being done to the conductor wires.

A hand-held camming device is shown which comprises a body portion 1 having two lever arms 2 extending therefrom which drive the two tuning fork connecto...
