Patent number: 7891882Abstract: A re-terminable, no-crimp ST-type optical connector assembly includes a spring-loaded ferrule holder assembly and a reusable activation system for termination of the assembly. The optical connector can be terminated by a suitable cam activation tool. The connector includes a housing, such as a bayonet, matable to a mating adapter, a backbone retained within a rear of the housing, a ferrule holder provided within the backbone, and a cam provided between the ferrule holder and the backbone. The ferrule holder includes an alignment key exposed to mate with a cam activation tool to lock rotation of the ferrule holder relative to other connector components. The cam includes a cam activation cutout at a front face thereof that mates with a cam activation tool interface to enable rotation of the cam between de-activated and activated positions, the cam activation cutout also receiving the alignment key of the ferrule holder therethrough.Type: GrantFiled: February 1, 2010Date of Patent: February 22, 2011Assignee: Panduit Corp.Inventors: Gregory L. Kuffel, Samuel M. Marrs, Shaun P. Brouwer, Robert T. Fitzpatrick, Phillip J. Irwin, Matthew M. Wagner

Patent number: 7806600Abstract: An improved, reversibly terminable fiber stub connector assembly is provided that can be readily and positively terminated in the field using simple termination tools. This allows repositioning or replacement of fiber optic cable field fibers if termination is not acceptable in performance. The tool may be a hand-held tool, or used in conjunction with a connector support structure to provide simplified and expeditious field termination of fiber optic cables. The cam tool can include a throughbore that enables connection of a patchcord to the stub fiber of the connector during or shortly after termination without removal of the termination tool. Accordingly, field testing of the connection can be made at the site of termination.Type: GrantFiled: February 28, 2008Date of Patent: October 5, 2010Assignee: Panduit Corp.Inventors: Samuel M. Marrs, Jerry A. Wiltjer, Shaun P. Brouwer

Publication number: 20090044709Abstract: A tool for installing a metal locking tie is disclosed. The tool includes a tension mechanism and a ball set and cut-off mechanism. The tension mechanism tensions the metal locking tie wrapped around a bundle. The ball set and cut-off mechanism includes a guide block and a shear block that engages the guide block. Once the tool tensions the metal locking tie, a ball set and cut-off handle is manually activated to push the guide block and the shear block forward in the tool thereby setting a ball in a metal locking tie head and shearing a portion of the tensioned metal locking tie.Type: ApplicationFiled: October 24, 2008Publication date: February 19, 2009Applicant: PANDUIT CORP.Inventors: Lawrence A.

Patent number: 6918704Abstract: A tunable fiber optic connector is disclosed. The connector includes a ferrule assembly comprising a ferrule and a ferrule holder for receiving the ferrule therein. The ferrule holder has a plurality of splines on the periphery of a front surface thereof, and a spring bears against a rear surface of the ferrule holder and applies a forward biasing force to the ferrule assembly. The connector also includes a housing having a central bore extending therethrough in which the ferrule assembly is located. The housing has at least one tuning arm within the bore for engaging the ferrule assembly, and the tuning arm allows the ferrule assembly to be tuned inside the housing without disengaging the ferrule assembly from the tuning arm. A method of assembling a tunable fiber optic connector is also disclosed.Type: GrantFiled: January 30, 2003Date of Patent: July 19, 2005Assignee: Panduit Corp.Inventors: Samuel M. Marrs, Gregory L.

Patent number: 6647197Abstract: The present invention is directed to a latch and guide rail arrangement that facilitates the insertion and removal of a module into and from a cable management system. This arrangement includes a latch arm assembly provided on a module and a guide rail assembly provided within an enclosure. As the module is inserted into the enclosure, the latch arms of the latch arm assembly mate with the guides of the guide rail assembly to lockingly engage the module with the enclosure. To remove the module from the enclosure, the latch arms are acted upon to release the arms from their mating relationship with the guides. With the present invention, modules can be replaced with great ease. Further, because the latch assembly is provided within the module itself, the latch assembly does not take up valuable space in the horizontal and vertical directions within the enclosure. As a result, the space within the enclosure can be fully utilized to accommodate the greatest number of connectors.Type: GrantFiled: June 2, 2000Date of Patent: November 11, 2003Assignee: Panduit Corp.Inventors: Samuel M. Marrs, Robert R. Brown, John J. Bulanda
