Patent number: 7963796Abstract: A bridge connector configured to electrically and mechanically couple adjacent circuit boards. The connector includes a connector housing that has a mating side configured to interface with board surfaces of adjacent circuit boards when mounted thereon. The housing includes a contact-receiving slot that at least partially defines a restricted space. The connector also includes a bridge contact that is held within the slot and the restricted space. The bridge contact has a pair of contact ends that are spaced apart from each other and project from the mating side. The contact ends are inserted into corresponding through-holes of the adjacent circuit boards when the housing is mounted thereon. The bridge contact is sized and shaped relative to the restricted space to float within the slot such that the bridge contact at least one of shifts and pivots therein.Type: GrantFiled: October 29, 2009Date of Patent: June 21, 2011Assignee: Tyco Electronics CorporationInventors: Matthew Sypolt, James Lee Fedder
