Patent number: 5425120Abstract: A strain relief boot (10) in combination with a connector (15). The strain relief boot (10) has a body (11) having a rigid portion (12) and a flexible portion (13). A center bore (14) extends through the body (11) and the connector (15) is slidingly disposed in the center bore (14). The body (11) has an inner wall (20) surrounding the center bore (14). A plurality of spaced-apart ribs (21) are formed on the inner wall (20) of the rigid portion (12). Each rib (21) has a top surface (22) and a pair of adjoining sidewalls (23). The ribs (21) extend inwardly into the center bore (14) and grip the connector (15) with a friction fit, retaining the strain relief boot (10) on the connector (15).Type: GrantFiled: March 7, 1994Date of Patent: June 13, 1995Assignee: The Whitaker CorporationInventors: Matthew A.
