Abstract

To test some machines, it is necessary to power down, remove the safety cover, attach the test wires, reinstall the safety cover and power up. After the test procedure is finished, the above must be reversed to remove the test wiring. The present power input quick connect and disconnect plug has a plastic portion 26 which slides over the terminal which has the connecting screws therein. The holes 10 in the plastic portion 26 are arranged to index with the screw contacts when correctly in place. The wiring 12 of the power is brought in to the selected ones of a plurality of banana plugs 15.

Power Input Quick Connect and Disconnect Plug

To test some machines, it is necessary to power down, remove the safety cover, attach the test wires, reinstall the safety cover and power up. After the test procedure is finished, the above must be reversed to remove the test wiring. The present power input quick connect and disconnect plug has a plastic portion 26 which slides over the terminal which has the connecting screws therein. The holes 10 in the plastic portion 26 are arranged to index with the screw contacts when correctly in place. The wiring 12 of the power is brought in to the selected ones of a plurality of banana plugs 15. The connector is internally wired so that the plungers 5, all 10 of which are simultaneously cammed to the down position which puts the end of the plunger in physical electrical contact with the terminal exposed through the opening 10 in the base plate 26. The plungers 5 are normally spring loaded in the upward position and are moved down by operation of the cam handle 14 which operates the cam 16 to essentially press the fulcrum lever 28 downward so that the plunger 5 is depressed, overcoming the spring loading in the upward direction. It should be appreciated that the particular connection can be made to the terminal board by pulling up on the cam handle 14, thereby completing the connections which are wired into the banana plugs
15. Some of the banana plugs 15 that do not have wiring input thereto are just redundant in some situa...
