Patent number: 6254410Abstract: Described is a connector in which a plug can be pulled out of a receptacle without producing stress in the connector itself or a circuit board on which the connector is mounted. The plug is inserted into the receptacle so that the side wall of the plug makes contact with the interior wall of the receptacle. When the plug and the receptacle are coupled, a fitting space is formed therebetween. When compressed air is injected into this fitting space, the plug will be pushed up by a rise in the air pressure and therefore the plug can be pulled out of the receptacle. The use of air pressure in the fitting space to pull out the plug is advantageous because it can be implemented without producing biased stress in the plug or the receptacle.Type: GrantFiled: May 19, 1999Date of Patent: July 3, 2001Assignee: International Business Machines CorporationInventors: Masahiko Sugiyama, Yasushi Yoshikawa
