Patent number: 7632116Abstract: A connector having a first connector portion with a first connection interface and a guide projection is disclosed. The connector also has a second connector portion with a second connection interface configured for insertion into the first connection interface. The connector also has a lever having a guide channel configured to receive the guide projection. The lever is linearly movably connected to the second connector portion and is positionally biased away from the second connector portion. While the guide projection is within the guide channel, movement of the lever from a fully positionally biased location with respect to the second connector portion initiates a change in a state of connection between the first connector portion and the second connector portion.Type: GrantFiled: February 12, 2008Date of Patent: December 15, 2009Assignee: Tyco Electronics AMP Korea Ltd.Inventors: Chul-Sub Lee, Kun-Taek Lim, Gi-Chan Kwon
