Patent number: 5868588Abstract: An electrical wedge connector with a sleeve and a one-piece wedge. The wedge has a rearward extension extending at one lateral side. When the wedge is fully inserted into the sleeve, the rear end of the wedge is substantially located inside the sleeve. However, the rearward extension extends past the rear end of the sleeve to provide a grasping surface. The rearward extension is preferably collapsible.Type: GrantFiled: April 23, 1997Date of Patent: February 9, 1999Assignee: Framatome Connectors USA, Inc.Inventors: Richard Chadbourne, Armand T.
