Patent number: 6926547Abstract: An arc quenching electrical connector has a male pin terminal which inserts longitudinally into a receptacle or terminal having a gassing wall engaged concentrically about the receptacle. During “hot unplugging” of the electrical connector, an arc is carried between a tip of the male pin and a contact surface of a leading end of the receptacle. The gassing wall extends over and is directly engaged to a portion of the contact surface. Because the gassing wall is also preferably an electrical insulator, the arc communicates electrically with the exposed contact surface and is biased directly against the gassing wall. The gassing wall, when heated by the adjacent arc, quenches or reduces the energy of the arc by releasing gas which eliminates arc erosion of the terminals.Type: GrantFiled: December 10, 2001Date of Patent: August 9, 2005Assignee: Delphi Technologies, Inc.Inventors: Thomas J.

Patent number: 6925757Abstract: A cable drive assembly for opening and closing a sliding vehicle door has first and second drums that are drivingly connected to each other via a tension spring that biases the drums in opposite directions. The drums include a catch that holds the first and second drums in a cocked condition where the spring is tensioned to provide slack in a closed loop cable to facilitate inserting a traveler attached to the cable into a track. The cocked drums are manually rotated in a drum housing in one direction to move the traveler and insert it into the track. After the traveler is inserted, the cocked drums are manually rotated in the opposite direction. This releases the catch so that the tensioned spring takes up the slack in the closed loop cable.Type: GrantFiled: April 25, 2003Date of Patent: August 9, 2005Assignee: Delphi Technologies, Inc.Inventors: William L.
